Salmonella disease in sub-Saharan Africa, and to specifically estimate the burden of bloodstream infections caused by the key pathogen, Salmonella enterica serovar Typhi. TSAP has achieved this ambitious target, finding high incidences of typhoid fever in both rural and urban populations in several countries in sub-Saharan Africa. The results of TSAP will undoubtedly dictate the direction of future typhoid fever research in Africa, and at last provides a key piece of the disease burden jigsaw puzzle. With the dawn of new Vi conjugate vaccines against Salmonella Typhi, the next priority for the typhoid community must be providing the required data on these vaccines so they can be licensed and provided to those in high-risk groups and locations across sub-Saharan Africa.The Typhoid Fever Surveillance in Africa Program (TSAP) was established in 2009 to fill the data void concerning invasive  Salmonella disease in sub-Saharan Africa led the World Health Organization (WHO) in 2008 to call for a continent-wide approach in generating more accurate disease incidence and antimicrobial susceptibility data. In 2009, the Bill & Melinda Gates Foundation provided the International Vaccine Institute funding to launch the Typhoid Fever Surveillance in Africa Program (TSAP). The aim of TSAP was to fill the data void regarding invasive Salmonella disease in sub-Saharan Africa and specifically to estimate the burden of bloodstream infections caused by the key typhoidal pathogen, Salmonella enterica serovar Typhi. TSAP was established to provide these data from 13 sentinel sites in 10 countries in sub-Saharan Africa. It was predicted that TSAP would provide contemporary information to assess whether disease incidence was sufficient to warrant the introduction of preventive measures, such as vaccination.The paucity of epidemiologic data regarding invasive Salmonella disease found that South-Central and East-Central Asia experienced the highest incidences of typhoid fever, with >100 cases per 100 000 person-years of observation [Prior global estimates for the burden of invasive ervation . The priervation .Clinical Infectious Diseases will undoubtedly influence the direction of future typhoid fever research in Africa and outline many key observations regarding typhoid fever epidemiology on this continent. In addition to high incidence rates, the focal (site-specific) nature of the disease in Africa will have substantial implications on the impact of potential intervention strategies. In the supplement article by Cruz and coauthors, it is shown that the incidence of typhoid fever in Ghana was substantially different between adjacent urban and rural areas [The findings and study methodology described in this supplement of al areas . Indeed,Salmonella spp. circulating in sub-Saharan Africa  [Salmonella Typhi and nontyphoidal Salmonella isolates in some locations. These data are largely reflective of other observations in further sites in Africa and Asia [Salmonella Typhi genomics work, also published in 2015, has shown the spread of the H58 lineage into Africa from Asia, predicting that antimicrobial resistance is a problem that is likely to increase over time [An additional key TSAP finding was the substantial prevalence of drug resistance and multidrug-resistant strains of invasive bmitted) . Notablyand Asia –9. Howevver time .Salmonella disease in remote settings with poor water quality and sanitation, where high disease burdens may now be anticipated. An inability to detect patients in remote settings results not only in an underestimation of the burden of invasive Salmonella disease, but also the associated disease severity and mortality. Ongoing investments by the Bill & Melinda Gates Foundation and other donors will hopefully yield better diagnostic tests that can be used at the point of care without the need for cumbersome and insensitive blood culture methods [The work presented in this supplement should raise the awareness of typhoid fever in rural locations in Africa, and follow-up studies should be conducted in other rural settings that were not sampled through TSAP. However, further studies, such as this and other typhoid fever studies, are confounded by the available diagnostic testing methods . Current methods .Salmonella disease is most prevalent in underprivileged communities with poor quality water supplies and limited sanitation. Often these communities are overcrowded and have restricted access to medical care. Preventive vaccination holds particular potential in reaching marginalized populations. However, in 2011, the Gavi Alliance stated that no financial support would be provided to countries supporting the introduction of the presently available Vi polysaccharide vaccines due to insufficient data on disease burden and limited vaccine efficacy in children aged <2 years. The lack of Gavi subsidy, combined with suboptimal performance of Vi polysaccharide vaccines, led to only very limited use of these vaccines. Five years later, 2 typhoid Vi conjugate vaccines indicated for use in children aged ≥2 years have been licensed in India, and several more are in development [Invasive elopment . Two preSalmonella disease, the research community must communicate not only the disease burden but also the effectiveness of vaccination, and the country-specific risk factors necessary to identify target groups/areas. Current research efforts are aimed at developing models that predict risk factors across sub-Saharan Africa to facilitate the assessment of possible Salmonella disease burden. However, such models can never replace real disease burden data in at-risk countries and communities, and it is unlikely that health ministries will approve mass vaccination programs on the basis of modeling data alone. Therefore, we again highlight the need for functional diagnostic tests and sustained disease surveillance alongside the genomic tracking of organisms and genes facilitating antimicrobial resistance.Possible future vaccination strategies in Africa include preemptive, responsive (in the case of an outbreak), and food handler immunization . HoweverSalmonella disease research is the identification of sites in Africa and Asia with consistently high burdens of disease for which water, sanitation, and hygiene (WASH) improvements can be implemented in conjunction with, or in comparison to, mass vaccination. Such studies would begin to quantify a more precise measure of the impact of WASH on disease incidence, and determine the extent of vaccination coverage alongside WASH improvements required for location-specific elimination of invasive Salmonella disease. Such data on the impact of the interventions will provide the most compelling case for decision makers to act upon.Perhaps the most critical next activity in invasive Salmonella disease as a public health priority on the African agenda. With the dawn of Vi conjugate vaccines and now-reliable incidence figures in Africa, the typhoid fever community really now needs to tackle the political issues surrounding typhoid fever immunization if we truly believe that regional elimination is a tangible target.In conclusion, data from the TSAP program have firmly positioned invasive


Stiffened plantar soft tissues break down easily  and these microscopic tears will heap together and develop into a large ulcer. In the USA, 85% of all non-traumatic amputations in diabetes patients arise from non-healing ulcers . In fact, foot ulceration is one of the major causes of hospitalization among the DM patients. 15% of the DM population are threatened by high ulceration risk during their life time (Aziz nather’s book). These findings elucidate the need of early identification of degenerating plantar soft tissue to prevent problematic tissue rupture, especially to diabetic and elderly patients. Non-invasive in vivo assessment that enables direct measurement of tissue’s mechanical response is therefore required. In order to differentiate between normal and pathological tissue, a stiffness reference is needed.The objective of this study is to conduct a multivariate analysis on the data of plantar tissue stiffness to a better understanding on the influences and the use of these parameters to predict the healthy tissue stiffness of these individuals.100 healthy subjects were recruited from National Seoul University (SNU) hospital for the experiment.During stiffness measurement , indentoTissue behavior was characterized via K, stiffness constant.Multiple linear regression of soft tissue stiffness was performed on several plantar locations. The independent variables are gender , bodyweight, height, BMI and age. Multiple analysis was chosen to study the combined effects of the independent variables on tissue stiffness.However, moderately strong relationship was found on the combined effects of these independent variables as shown in Table This suggest that the decision to ignore the influence of gender, age, bodyweight, height and body mass index on plantar soft tissue stiffness should be carefully considered. The combined effect of these independent parameters may subtly influence the accuracy of the study analysis.


The stone marten is a widely distributed mustelid in the Palaearctic region that exhibits variable habitat preferences in different parts of its range. The species is a Holocene immigrant from southwest Asia which, according to fossil remains, followed the expansion of the Neolithic farming cultures into Europe and possibly colonized the Iberian Peninsula during the Early Neolithic . However, the population genetic structure and historical biogeography of this generalist carnivore remains essentially unknown. In this study we have combined mitochondrial DNA (mtDNA) sequencing (621 bp) and microsatellite genotyping (23 polymorphic markers) to infer the population genetic structure of the stone marten within the Iberian Peninsula. The mtDNA data revealed low haplotype and nucleotide diversities and a lack of phylogeographic structure, most likely due to a recent colonization of the Iberian Peninsula by a few mtDNA lineages during the Early Neolithic. The microsatellite data set was analysed with a) spatial and non-spatial Bayesian individual-based clustering (IBC) approaches , and b) multivariate methods [discriminant analysis of principal components (DAPC) and spatial principal component analysis (sPCA)]. Additionally, because isolation by distance (IBD) is a common spatial genetic pattern in mobile and continuously distributed species and it may represent a challenge to the performance of the above methods, the microsatellite data set was tested for its presence. Overall, the genetic structure of the stone marten in the Iberian Peninsula was characterized by a NE-SW spatial pattern of IBD, and this may explain the observed disagreement between clustering solutions obtained by the different IBC methods. However, there was significant indication for contemporary genetic structuring, albeit weak, into at least three different subpopulations. The detected subdivision could be attributed to the influence of the rivers Ebro, Tagus and Guadiana, suggesting that main watercourses in the Iberian Peninsula may act as semi-permeable barriers to gene flow in stone martens. To our knowledge, this is the first phylogeographic and population genetic study of the species at a broad regional scale. We also wanted to make the case for the importance and benefits of using and comparing multiple different clustering and multivariate methods in spatial genetic analyses of mobile and continuously distributed species. In continuous populations, genetic structure vary from a single identifiable group of individuals, with gene flow only restricted by the distance among them, to an unknown number of subpopulations separated by barriers to gene exchange ,2. SpeciMartes foina, Erxleben, 1777) is one of the most widely distributed mustelids in Eurasia )The phylogeography of the stone marten in the Iberian Peninsula is compatible with a single recent colonization of the region, possibly in the early Holocene, followed by population expansion sometime later. In turn, its contemporary genetic structure is characterized by a significant pattern of IBD and an apparent differentiation of the populations at the extreme of an NE-SW axis. To our knowledge, this is the first phylogeographic and population genetic study of the stone marten at broad regional scale. This case study also shows the usefulness of comparing and integrating multiple different techniques in the analysis of spatial genetic structure of mobile and continuously distributed species. Comprehensive analyses and tests of isolation by distance and clinal variation are an essential complement to clustering methods aiming to identify distinct genetic units, in particular due to the difficulties of the latter approaches in dealing with populations under IBD.The genetic breaks detected in the Iberian stone marten population seemed largely related to the major river basins in the peninsula. However, linear barriers are only one of the multiple ways of how landscapes can influence gene flow .

The development of technological routes to convert lignocellulosic biomass to liquid fuels requires an in-depth understanding of the cell wall architecture of substrates. Essential pretreatment processes are conducted to reduce biomass recalcitrance and usually increase the reactive surface area. Quantitative three-dimensional information about both bulk and surface structural features of substrates needs to be obtained to expand our knowledge of substrates. In this work, phase-contrast tomography (PCT) was used to gather information about the structure of a model lignocellulosic biomass (piassava fibers).The three-dimensional cellular organization of piassava fibers was characterized by PCT using synchrotron radiation. This technique enabled important physical features that describe the substrate piassava fibers to be visualized and quantified. The external surface area of a fiber and internal surface area of the pores in a fiber could be determined separately. More than 96% of the overall surface area available to enzymes was in the bulk substrate. The pore surface area and length exhibited a positive linear relationship, where the slope of this relationship depended on the plant tissue.We demonstrated that PCT is a powerful tool for the three-dimensional characterization of the cell wall features related to biomass recalcitrance. Original and relevant quantitative information about the structural features of the analyzed material were obtained. The data obtained by PCT can be used to improve processing routes to efficiently convert biomass feedstock into sugars. Biomass is the only domestic, sustainable, and renewable primary energy fuel source in the near term. Alternative energy initiatives have now rekindled enormous interest in the development of new and cost-effective processes for converting plant-derived biomass to liquid fuels. This combined effort is global, serious, and hopefully long lasting. A major component of the current focus on alternative energy is associated with environmental issues, particularly with the huge effect of the usage of fossil fuels on the carbon cycle and greenhouse gas emissions. Although initially debates raged, the promise and appropriateness of biofuels are now clearly apparent.A biorefinery is envisioned to contain four major sections: feedstock harvest and storage, thermochemical pretreatment, enzymatic hydrolysis, and sugar fermentation to ethanol or other fuels. Existing biomass conversion schemes typically rely on a combination of chemical and enzymatic treatments. A pretreatment step is usually conducted to reduce recalcitrance by depolymerizing and solubilizing hemicellulose and lignin. In addition, pretreatment typically breaks down the rigidity of biomass and decreases the physical barriers to mass transport . HoweverCellulase enzymes must bind to the surface of substrate particles before hydrolysis of insoluble cellulose can occur. The three-dimensional structure of such particles (including their microstructure) and the size and shape of cellulase enzyme(s) are the main limiting factors in the enzymatic hydrolysis of lignocellulosic biomass ,3. CelluThe external surface area of a material is closely related to the particle shape and size and has been estimated by laser diffraction and electron microscopy techniques -11. ConvThe gross surface area of a material is generally measured by its sorption of nitrogen, argon, or water vapor . The mosRecently, conventional tomography  was used to explore the three-dimensional microstructure of sugarcane bagasse particles . This noIn this decade, the use of X-ray phase imaging techniques including phase-contrast tomography (PCT) has attracted extensive attention from scientific and technological communities . The intAttalea funifera) were used as a model material [The anatomy of plant cell walls was investigated using PCT to gain a deeper understanding of the cellular organization. In this context, piassava fibers , while the second peak originates from pores with surface area between 5,600 and 6,800 pixels squared . Similar bimodal distributions of biomass features have been observed at different scales. For instance, Wang et al. [et al. [Figure g et al.  and Moon [et al.  reportedTo examine the distribution of surface areas of individual pores, Figure Because direct physical contact between an enzyme and substrate is required for hydrolysis, the amount of surface area available for such contact strongly affects the reaction rate ,4. In thet al. [Many researchers have suggested that particle length affects enzyme access to cellulose microfibrils ,24,25. Het al.  recently2/g, which is the same order of magnitude as that obtained from PCT. However, this area was calculated based on the adsorption cross section of the nitrogen molecule. Therefore, the value obtained from nitrogen isotherms surely overestimates the surface area of a substrate accessible to enzymes [For comparison purposes, nitrogen adsorption measurements were obtained to determine the surface area of the fibers by the BET method. This method measures both the interior and exterior surface areas where a nitrogen monolayer is adsorbed by a sample. The surface area of the fibers determined by the BET method was 0.6379 mX-ray tomography combined with imaging processing techniques provides information about each physical feature separately , so the relationship between different parameters can be also obtained. Figure Besides the pore surface area and size, the effect of cell wall thickness on the structural recalcitrance of the lignocellulosic biomass is also discussed . To explExtracting the three-dimensional features of bulk particles can provide extremely valuable information to better understand the substrate and consequently biomass recalcitrance. PCT combined with image processing enabled us to extract individual physical features of the internal lumens of piassava fibers and also to estimate gross characteristics such as the area available to react with enzymes. Many questions such as why it is difficult for some plants, or portions of plants, to release their sugars and what structural features change to render pretreated biomass digestible can be thoroughly investigated using the approach described in this work. By answering these questions, insights to develop more efficient pretreatment processes and less recalcitrant substrates will be provided.PCT allowed us to directly visualize the bulk and three-dimensional cell wall architecture in biomass. The imaging and processing techniques used here gave reliable measurements of the surface area of individual pores, pore length, and distance to cell wall edge, which are the parameters required to increase knowledge of structural biomass recalcitrance. In this context, plant cell walls from piassava fibers were used as a model to examine what is currently known about cell wall structures related to biomass.Three-dimensional imaging revealed the complex and heterogeneous cellular structure of the piassava fibers. Structural features were visualized and the textured external surface could also be resolved because of the extremely high sensitivity of PCT. Statistically relevant information on the surface area, length, and number of pores in bulk biomass was obtained from the tomograms.Quantitative analyses revealed that the surface area of individual pores in piassava fibers exhibited a bimodal distribution. Structural features  could be determined separately, allowing the relationship between different parameters to be determined. A positive linear relationship was found between pore surface area and length.The total accessible surface area of the piassava fibers directly measured by PCT was of the same order of magnitude as that obtained by the BET method. However, using PCT, the external surface of individual fibers and available surface area of the bulk material at the micrometer scale could be obtained separately. It could be confirmed, therefore, that the external surface of the fiber has only a minor contribution to the gross available surface area.This investigation is an important step towards understanding the influence of structural and morphological characteristics on biomass recalcitrance. Using PCT, important outstanding questions in the area of recalcitrance and deconstruction of biomass can be clarified, which will provide new insights to obtain more efficient substrates and pretreatment processes. Future experiments will concentrate on strategic feedstocks for ethanol production in large-scale biorefineries such as sugarcane bagasse and corn stover.3 [Piassava fibers extracted from the leaves of a palm tree native to the state of Bahia in the northeast region of Brazil were used in this work as model lignocelluloses . The fib3 . The fib3 .et al. was applied [The cellular organization in the piassava fibers was studied by PCT using synchrotron radiation. Measurements were performed at the imaging setup of the BAMline at the German storage ring BESSY (Berliner Elektronenspeicherring - Gesellschaft für Synchrotronstrahlung m.b.H.), operated by the HZB  . During  applied .The evaluation of tomographic volume was focused on the cell wall organization. Voxels were identified as belonging either to pores or plant cell walls by applying an intensity threshold based on their gray level. Information on the number of intercellular spaces (pores) and their geometric properties was extracted from tomograms using a commercial code. The distribution of cell wall thickness was also obtained using ImageJ software.


We noticed an error in one of our presented analyses. One mismatched brain image was accidentally included in the voxel-based-morphometry (VBM) analysis. Thus, arousal and valence values were consecutively not properly assigned to the morphological brain data of the other included participants. Of three analyses implemented in this study , only the VBM analysis was affected but the others remain untouched. Therefore, we re-conducted the whole VBM analysis with the correct allocation of data. The corrected results showed changes in the whole-brain and regional correlations compared to the originally presented results. However, the correlations in the expected areas of the original manuscript remain significant for arousal and valence difference scores.p < 0.001 uncorrected level, and the ROI analysis still showed significant correlations with gray matter intensities in the right SFG (BA9).Fortunately, these results do not impact the main implications and neither invalidate the conclusions derived from the study nor introduce differing directions of inference.

An essential step in the discovery of molecular mechanisms contributing to disease phenotypes and efficient experimental planning is the development of weighted hypotheses that estimate the functional effects of sequence variants discovered by high-throughput genomics. With the increasing specialization of the bioinformatics resources, creating analytical workflows that seamlessly integrate data and bioinformatics tools developed by multiple groups becomes inevitable. Here we present a case study of a use of the distributed analytical environment integrating four complementary specialized resources, namely the Lynx platform, VISTA RViewer, the Developmental Brain Disorders Database (DBDB), and the RaptorX server, for the identification of high-confidence candidate genes contributing to pathogenesis of spina bifida. The analysis resulted in prediction and validation of deleterious mutations in the SLC19A placental transporter in mothers of the affected children that causes narrowing of the outlet channel and therefore leads to the reduced folate permeation rate. The described approach also enabled correct identification of several genes, previously shown to contribute to pathogenesis of spina bifida, and suggestion of additional genes for experimental validations. The study demonstrates that the seamless integration of bioinformatics resources enables fast and efficient prioritization and characterization of genomic factors and molecular networks contributing to the phenotypes of interest. The identification of genomic variations contributing to specific phenotypes of direct medical relevance is an ultimate goal of numerous studies in human genetics. The development of solid weighted hypotheses on the functional effects of a sequence variant is an essential step for gaining insights into a genetic architecture of a disease and for the efficient planning of experiments. However, as the volume and complexity of biological information increases, it demands sophisticated analytical workflows involving multitude of steps for extraction of actionable knowledge. In the past years much attention in the bioinformatics literature was given to data integration A number of excellent bioinformatics platforms and tools have been developed in the recent years to support various steps of analysis of high-throughput data and prioritization of genomic variants , using whole genome next generation sequence (NGS) data for affected patients and their parents. We show advantages of an integrated approach for both hypothesis-based and discovery-based methods for identification and prioritization of genetic factors contributing to complex developmental phenotypes. The presented example also serves as a proof of concept for the integration of various computational resources for the high-throughput analysis of genomic variants.We have integrated the following analytical resources developed by four groups: (1) VISTA RViewer The approach supports multiple entry points for annotation and analysis of translational data , as well as batch queries via Web-based user interfaces or Web-services see . The folThe sections below will describe the components of the integrated distributed analytical pipeline in more details.VISTA RViewer In the LYNX - VISTA integrative system, RViewer plays a dual role, both calculating a number of functional parameters used by LYNX in further analysis, and visualizing a set of genomic regions with prioritized variant provided to a user as an output of the system. In particular, it finds a genomic position of a submitted by a user variant , associates it with UCSC isoforms, calculates deleteriousness of the non-synonymous coding SNPs using Polyphen2 http://lynx.ci.uchicago.edu) is an integrated bioinformatics platform and a knowledge extraction engine for annotation and analysis of high-throughput biomedical data inter alia associated pathways, diseases, phenotypes, molecular interactions, Gene Ontology categories, toxicogenomic information displayed according to the user preferences. All information related to the objects is easily accessible via user interface and available for download in tab-delimited, XML or JSON formats (Web Services).Lynx  as initially developed in the gene prioritization tool PINTA Developmental Brain Disorders Database (DBDB). In a lot of cases the analysis of translational data requires integration of the domain- and project specific data . Significant amount of this information is already integrated into the Lynx knowledge base. However, the described analytical pipeline can be customized to integrate additional information resources (e.g. public databases and private collections) to meet the user requirements. Here we present the integration of the information from the Developmental Brain Disorders Database (DBDB) https://www.dbdb.urmc.rochester.edu/home) is a publicly available, curated on-line repository of genes, phenotypes, and syndromes associated with human neurodevelopmental disorders DBDB (http://raptorx.uchicago.edu) RaptorX  The systems described above provide complementary services for identification and characterization of causative factors and molecular mechanisms associated with phenotypes of interest. While they all act as individual entry points for the end users to start the analysis, the implemented integrative tools provide an environment for seamless data transfers between the systems. Following are a few examples of the interfaces built towards integrating these systems:Lynx and RViewer. After entering a list of genes, genetic variants (SNPs) or regions (CNVs) in the Lynx system, the users are provided with the interface to submit these datasets to RViewer for the annotations of the genomic regions including variants, transcription factor binding sites, experimental and computational enhancers and many others. The annotations data for transcription factor binding sites and enhancers is periodically fetched from the RViewer and integrated into the Lynx knowledge base and is used for the enrichment analysis of the genes of interest.Lynx and DBDB. The richly curated data in DBDB make possible providing weights to the genes of interest for particular phenotypes. These data can be used in Lynx's networks based prioritization interface. DBDB also provides direct links to the Lynx's single gene and multi-gene annotation pages.Lynx and RaptorX. Lynx provides a novel interface for submission of protein sequences directly to RaptorX, thus creating capabilities for RaptorX to predict the structure and binding site for high-confidence genes flawlessly.Spina bifida is a common congenital birth defect with an average worldwide prevalence of one case per 2000 births. It manifests itself as failed closure of the embryonic neural tube In our study the Laboratory of Neurogenetics and Development  performed the whole genome sequencing for four patients with spina bifida, and four parents with normal phenotype from the same consanguineous family. The resulting SNPs were analyzed using both discovery-based, and hypothesis-based approaches for identification of the genetic factors contributing to the birth defect phenotype. The analysis included the following steps  in the exonic and UTR regions of both the patients and unaffected parents genes  in SLC19A1 placental folate transporter in general population is 30∶25∶45 The reconstruction has shown that SLC19A1 protein has a typical MFS membrane transporter architecture with N- and C-terminus domains containing six trans membrane helices each in-silico simulation and energy minimization study of the mutation (see Text S1 in 3 to 541 Å3) and 28% decrease in the surface area of the cleft (from 442 Å2 to 328 Å2) , VISTA , and RaptorX . In the spina bifida example, the DBDB knowledge base was used as a source of domain-specific neurodevelopmental data. The resulting combined knowledge base may be used for extensive annotation of data and the results of analyses by these multiple resources. Another advantage offered by the described platform is the seamless integration of tools that supports the workflows spanning across the contributing resources see . DatasetThe following types of analysis are currently integrated: RViewer provides an extensive annotation of genomic intervals of interest ; Lynx enrichment analysis allows the user to identify biological functions and phenotypes over-represented in the user datasets; Lynx network-based gene prioritization predicts high-confidence genes contributing to disease phenotypes; RaptorX server gives predictions of the 3D protein structure for protein sequences without close homologs in PDB, solvent accessibility, and disordered regions thus facilitating understanding of protein-ligand interactions.We are working on the expansion of the array of available analytical services integrated in the described environment, specifically to provide access to additional domain-specific resources (e.g. cancer and cardiovascular studies). As the volume and complexity of biological information continues to increase, the seamless integration of bioinformatics platforms will offer a practical solution for the needs of biomedical studies.Materials S1Supporting text, figures and table.

Obstructive sleep apnea (OSA) syndrome is a prevalent condition characterized by repeated episodes of obstruction of the upper airway, leading to intermittent hypoxemia and important endothelial and anatomical dysfunctions that cause cardiovascular and cerebrovascular disease. The finding of the relationship between OSA and hypertension, especially resistant hypertension (RHT), has increased the interest in therapeutic strategies that affect renal sympathetic activity in these patients. The observational studies published until now demonstrated that renal denervation therapy can reduce the severity of OSA syndrome. Renal sympathetic denervation (RDN) could be a future therapeutic possibility for conditions other than RHT, such as atrial fibrillation, heart failure, obesity, and OSA syndrome, where renal sympathetic system plays an important physiological role. The aim of this review was to elucidate the implications of renal sympathetic activity in OSA syndrome. The apnea-hypopnea sleep (AHS) syndrome was firstly described in 1976 by Guilleminault et al. [The apnea-hypopnea index (AHI) is used to measure the severity of obstructive apnea. Diagnosis is defined as an AHI > 5 accompanied by disease-related symptoms .OSA syndrome and its relationship with HT have been well established . An incrHT is a major public health issue worldwide, not only because of its high prevalence , but also because of the impact on cardiovascular morbidity and mortality. Population studies have reported that one-third of the hypertensive patients develop apnea-hypopnea sleep (AHS) syndrome and that 40% of patients with AHS syndrome are hypertensive .It has been observed that OSA syndrome is present in 75% of patients diagnosed with RHT; nevertheless, its prevalence is much lower (38%) in hypertensive patients with controlled blood pressure (BP) . CardiovThe increase of sympathetic activity is involved in the development, management, and the evolution of the hypertensive state of patients with OSA syndrome. It implies that sympathetic deactivation can be seen as a goal of treatment. Small observational studies published so far reported that RDN can decrease the severity of OSA syndrome. RDN therapy is having an important role in the treatment of other diseases apart from HT; in fact, beneficial effects of RDN therapy in diseases other than HT where the renal sympathetic system plays an important role have been reported, such as atrial fibrillation, heart failure, obesity, or diabetes. The aim of this review was to elucidate the implication of renal sympathetic activity on the OSA syndrome.Many physiopathological factors have been described involved in the development of AHS syndrome. Some of the factors that promote the collapse of the upper airway are the narrowing of this airway, excessive loss of muscle tone, and defective upper airway protective reflexes mediated by overstimulation of sympathetic nervous system –16.(1)Intermittent hypoxia due to apnea and hypopnea triggers an excess of sympathetic activity by the activation of the carotid chemoreceptors; it leads to direct vasoconstriction and the subsequent stimulation of the renin-angiotensin-aldosterone system (RAAS) as well as increased levels of endothelin and angiotensin II. Activation of the renin-angiotensin axis produces fluid retention due to sodium reabsorption; it seems to lead to edema in the peripharyngeal walls, which predisposes to upper airway obstruction , 19.(2)β1 adrenoreceptors; this increases the circulating volume when sodium retention increases, and renal blood flow decreases through the α1 adrenoreceptors.The increase in the sympathetic tone in patients with OSA syndrome produces renal activation of the autonomic nervous system. The kidneys are connected to the brain by afferent and efferent pathways. Hyperactivity of the autonomic nervous system stimulates renin release from the juxtaglomerular apparatus, then activating  Renal afferent activation determines an increase of the sympathetic activity in the central nervous system (CNS), involving the vascular system, heart, and the other peripheral organs, leading to HT and its degree of severity .(3)Sympathetic hyperactivity reduces the dilating effect of the upper airway muscles mediated by the genioglossal nerve and predisposes to pharyngeal obstruction . Excess (4)The physiological stimuli associated with apnea produce the formation of endogenous vasoactive substances and decrease the levels of nitric oxide, a potent vasodilator. It has been demonstrated that the use of CPAP during the night increases the circulatory levels of nitric oxide. Ischemic and reperfusion events associated with apnea lead to endothelial injury .The neurophysiological factors involved in the development of HT in patients with AHS syndrome are interacting with each other . IncreasSymplicity HTN-1, HTN-2, and HTN-3 trials are the most relevant studies concerning the clinical use of RDN therapy –32. The Nevertheless, the Symplicity HTN-3 study which enrolled 535 randomized patients with a 6-month follow-up was not able to confirm the results previously obtained. There was no significant between-group difference in the change in office blood pressure at 6 months. This finding has questioned its efficacy. However, the responses with regard to systolic and diastolic blood pressure were significantly greater in the denervation group than in the sham-procedure group. It seems to be demonstrated that RDN therapy reduces renal sympathetic secretion and leads to a systemic decrease in sympathetic tone.Some small studies have demonstrated a significant decrease of AHI in patients with OSA syndrome after undergoing RDN; this can explain the relationship between HT, OSA syndrome, and excess sympathetic tone. RDN has the potential effect of decreasing sympathetic overactivity in patients with OSA syndrome .The first studies demonstrating this relationship were carried out in animal models. RDN decreased BP rises and the incidence of secondary arrhythmias, during postapneic periods in OSA syndrome models. This decreased the susceptibility of these animal models to develop atrial fibrillation . FurtherA recent meta-analysis published by Shantha and Pancholy  includedn = 10), it showed relevant results. AHI was measured in the 10 patients by polysomnography, before and 6 months after undergoing RDN. The authors reported a decrease in the severity of OSA syndrome in the patients after RDN, although without statistical significance due to the small size of the sample. The authors also reported that RDN therapy significantly decreased BP levels and improved the glycemic control of patients [Three of these studies were carried out in Europe, where the RDN technique is more accepted. Of the five studies, that of Witkowski et al. evaluated specifically the role of RDN in the AHI, BP, and glycemic control. Although the number of patients involved in the study was small , described by Sullivan et al. in 1981, is the treatment of choice for sleep apnea in hypertensive patients . It imprMontesi et al.  carried The mechanisms of the association between BP and daytime sleepiness could be related to the arousals, which occur at the end of the respiratory events, coinciding with repeated BP surges. Intermittent ischemic episodes increase BP by the activation of type I angiotensin II receptor. It seems that overactivation of the renin-angiotensin axis occurs independently of other factors . RDN couAlthough the hypotensive effect of CPAP seems to be moderate, decreases of 5 mm Hg in DBP reduce the risk of cerebrovascular accidents by 42% and all cardiovascular events by 31% .Significant decrease of BP only 3 weeks after onset of CPAP treatment reinforces the importance of studying and treating OSA syndrome in patients with RHT.CPAP is the treatment of choice in the management of patients with OSA; its use in the treatment of RHT is becoming increasingly more widespread. The important implications of morbidity in OSA syndrome make it necessary to seek new therapies that intervene in the physiological mechanisms related to cardiovascular events in these patients. Nowadays, it has been demonstrated that RDN improves the severity of OSA syndrome in patients with RHT. In this respect, RDN treatment could be considered in patients with excess sympathetic tone. Nevertheless, further clinical trial should be required before renal denervation can be applied to the study of OSA and other conditions such as obesity hypertension.


Longitudinal functional imaging studies of stroke are key in identifying the disease progression and possible therapeutic interventions. Here we investigate the applicability of real-time functional optoacoustic imaging for monitoring of stroke progression in the whole brain of living animals.The middle cerebral artery occlusion (MCAO) was used to model stroke in mice, which were imaged preoperatively and the occlusion was kept in place for 60 minutes, after which optoacoustic scans were taken at several time points.in-vivo as a localized hemodynamically-compromised area adjacent to the region of stroke-induced perfusion deficit.Post ischemia an asymmetry of deoxygenated hemoglobin in the brain was observed as a region of hypoxia in the hemisphere affected by the ischemic event. Furthermore, we were able to visualize the penumbra The intrinsic sensitivity of the new imaging approach to functional blood parameters, in combination with real time operation and high spatial resolution in deep living tissues, may see it become a valuable and unique tool in the development and monitoring of treatments aimed at suspending the spread of an infarct area. Scans were made preoperatively for later comparison to post-operative scans and as a control. Infarct volume analysis was performed after the last in-vivo scan by means of histology after sacrificing the animal.In this study, real-time MSOT imaging The non-invasive optoacoustic scans were performed in vivo by acquiring whole-brain tomographical datasets formed from coronal slices imaged at 15 different excitation wavelengths between 710 and 850 nm. The system used was a cross-sectional small animal MSOT scanner, which uses a 64-element ultrasonic array for real-time 2D scanning All animals were treated in accordance with FELASA guidelines and the study was approved by local government . This study saw seven mice  operated upon and scanned; the mice were anesthetised with 1.5% isoflurane  vaporized in pure oxygen; scans were made preoperatively for later comparison to post-operative scans and as a control.Following the initial validation scan, the MCAO procedure in-vivo scan was performed. After 60 min of ischemia, the filament was retracted, the wound closed, and the animal allowed to survive for 24 hours. After 24 h, a final MSOT scan was performed under anesthesia.During occlusion, a second 2 and the local absorption coefficient −1. The reconstructed images are subsequently spectrally unmixed, using a linear regression method 2 in the brain. For every data point in the reconstructed images, the algorithm uses least-squares to match the recorded optoacoustic spectrum to the known absorption spectra of Hb and HbO2. This results in distribution maps of the two states of hemoglobin, which are regarded as the dominant absorbers in biological tissue. Spectral unmixing is essentially performed on a per-pixel basis by solving the set of linear equations:The tomographic optoacoustic data recorded at each wavelength were reconstructed by interpolated model-matrix inversion Additional analysis using single wavelength images was performed. The isosbestic point of hemoglobin is close to 790 nm, thus signals recorded at this wavelength are closely related to the total cerebral blood volume (CBV). In order to analyze overall trends in the study, two areas were compared pre-, during, and post-ischemia at this wavelength. The comparison made was ratios of the mean value of a region of interest (ROI) in the ischemic cortex to the mean of its contralateral counterpart . The size of the area of Hb-asymmetry and the associated signal strength therefore appear to be closely related to the histological infarct volume. Some mice appear to show little or no Hb signal in the cortex even after reperfusion  for the monitoring of stroke progression following MCAO in the whole brain of living mice. The The ratios between hemispheres demonstrate different longitudinal behavior in different areas of the brain. While cortex ratios dropped during ischemia for all mice, returning to nearly normal values after reperfusion, similar ratios in the striatum areas increased for all mice during artery occlusion and remained elevated at 24 h following reperfusion. It was previously confirmed that, due to the less pronounced reduction of blood flow in the penumbral region, autoregulatory dilation of the local cerebral circulation leads to an increase of CBV Indeed, the investigation into potential treatments for stroke necessitates non-invasive longitudinal studies. Here, through non-invasive functional MSOT imaging, it was possible to visualize the penumbra as a localized hypoxic area in the brain. Potential future studies could investigate the how different treatments affect the development of this hypoxic area, and thus limit the spread of the necrotic core. From a technical perspective, it would be ideal to simultaneously capture true three-dimensional MSOT data from the entire brain, which is a subject of our ongoing investigations. This would further allow achieving isotropic resolution in the imaged region, reduce out-of-plane image artifacts and lead to overall improvement of the data quantification abilities.In summary it has been shown that, although the ischemic lesion was not directly detectable using MSOT, an adjacent localized region with characteristic hemodynamic disturbance was detected throughout the brain that most certainly reflects the ischemic penumbra. The unique capacity to monitor the penumbra development non-invasively and longitudinally without the introduction of contrast agents demonstrates further potential for investigating the ability of acute stroke therapies aimed at limiting the lesion size. Finally, the intrinsic sensitivity of MSOT to functional blood parameters, in combination with real time operation and high spatial resolution in deep tissues, may see it become a valuable and unique tool in functional stroke studies.


Although the measles vaccine has been part of routine national childhood vaccination programs throughout Europe, measles remains a public health concern. High numbers of cases and outbreaks have occurred throughout the European continent since 2011, and an increasing number of cases have been reported in Turkey since 2012. During a recent measles outbreak in Turkey, 2 pregnant women contracted measles prior to delivering preterm infants at Hacettepe University Hospital. Measles virus genomic RNA and IgM antibodies against measles were detected in the cord blood of infants and mothers in both cases. The infants were treated with intravenous immunoglobulin (IVIG) and vitamin A. Transient thrombocytopenia was present in 1 infant and treated with an additional dose of IVIG and vitamin A. The infants were discharged, without complications, within 10 days of birth. The successful treatment of these cases suggests that infants who have been exposed to, or infected with, measles may benefit from cotreatment of vitamin A and IVIG. Prior to the introduction of measles vaccination programs, a majority of individuals contracted the measles virus early in childhood and developed lifelong immunity; thus, measles infection during pregnancy was an unusual event. The distribution of infected individuals has shifted to older age groups in the vaccine era, with proportionately more adolescent and young adults affected owing to a lack of complete vaccination coverage as well as primary and secondary vaccine failure. The potential risk for measles infection in women of childbearing age has therefore increased . MaternaAt the end of 2011, measles resurged throughout Turkey and further increased during 2012 through May 2013. At the time of this publication, 4,172 cases have been reported, constituting an epidemic. In this case report, we describe 2 preterm infants who contracted measles during this epidemic and their successful treatment with combined IVIG and vitamin A.Two mothers who had contracted measles during an outbreak gave birth to preterm infants at Hacettepe University Hospital in Ankara, Turkey, in February 2013. We describe both cases and their course of treatment below and in 1/7 weeks, because of fetal distress, from a 38-year-old mother with measles pneumonitis. She was born on the sixth day after her mother's exanthema necessitated noninvasive ventilation because of severe pneumonia  was delivered by caesarean section at 34neumonia . The motμL and had dropped to 44,000/μL after 4 days (3/kg thrombocyte transfusion. The newborn was discharged in a good condition on the tenth day.Cord blood and serum samples were collected from the infant and mother soon after delivery. An enzyme-linked immunosorbent assay (ELISA) indicated the presence of measles-specific IgM and IgG antibodies in the mother. The infant's serum was positive by ELISA for the presence of measles specific IgM but negative for the presence of IgG antibodies. However, RNA extracted from cord blood mononuclear cells for use in a measles virus-specific reverse transcriptase-PCR assay indicated the presence of measles virus . On her r 4 days . ThromboA preterm female infant (weight 2630 g) was delivered by vaginal route from a 27-year-old mother with measles pneumonitis at 36 weeks, on the fourth day after her mother's exanthema had disappeared. The mother's medical history indicated that she had received only 1 dose of the measles vaccine, and the serum obtained 1 month previously was negative by ELISA for antimeasles IgG and IgM. The infant showed no clinical signs of the disease at birth.Cord blood and serum samples were collected from the infant and mother soon after the delivery and serum specimens were tested for the presence of measles-specific IgM, IgG, and RNA as described above. The infant's serum was positive by ELISA for both measles-specific IgM and IgG antibodies. Measles-virus-specific RNA extracted from cord blood mononuclear cells was positive as well . The infThe widespread availability of the 2 dose measles vaccine program has led to a marked decrease in the incidence of measles and resulted in less natural boosting of antibody levels. However, depending on the schedule of immunization, immunity declines in late childhood and adolescence leading to gaps in the immunity of adults. Further, measles outbreaks may occur in susceptible individuals despite widespread childhood vaccination . Indeed,Primary protection against infectious diseases at birth is provided mainly by maternal antibodies and several factors determine the amount of maternal antibodies in young infants. The coverage of universal immunization programs influences the amount of maternal antibodies and a higher level of coverage reduces the probability of natural antibody boosting. Infants of vaccinated women were born with significantly fewer antibodies compared to infants of naturally immune women. Because increased childbearing age is directly related to the prolongation of the time between childhood vaccination and childbirth, maternal antibodies are prone to be low. The rate of decay of maternal antibodies after birth determines the duration of protection in infants , 9–11. YThe effect of measles during pregnancy on the fetus has been the focus of several studies. Limited data is available regarding the spectrum of neonatal illness, but it can range from mild to rapidly fatal forms. Early studies have documented adverse fetal outcomes including increased mortality during the first two years of life, and it appears that the mortality rate of congenital measles is higher in preterm than in full-term infants , 8. InteThe low morbidity of recent cases of congenital measles may reflect the effects of prophylactic immunoglobulin . These tIn conclusion, the two cases of congenital measles reported here highlight the need to improve immunization strategies for adolescents and young adults, which could decrease the incidence of maternal measles. Additionally, the survival of these preterm infants suggests that cotreatment with vitamin A and IVIG is a successful strategy for vulnerable individuals who have low levels of protective measles antibodies.


Taenia solium brain parenchymal cysts leads to an acute pericystic host inflammatory response and blood brain barrier breakdown (BBB), commonly resulting in seizures. Naturally infected pigs, untreated or treated one time with praziquantel were sacrificed at 48 hr and 120 hr following the injection of Evans blue (EB) to assess the effect of treatment on larval parasites and surrounding tissue. Examination of harvested non encapsulated muscle cysts unexpectedly revealed one or more small, focal round region(s) of Evans blue dye infiltration (REBI) on the surface of otherwise non dye-stained muscle cysts. Histopathological analysis of REBI revealed focal areas of eosinophil-rich inflammatory infiltrates that migrated from the capsule into the tegument and internal structures of the parasite. In addition some encapsulated brain cysts, in which the presence of REBI could not be directly assessed, showed histopathology identical to that of the REBI. Muscle cysts with REBI were more frequent in pigs that had received praziquantel  than in those that were untreated . Similar results were found in the brain, where 20.7% of 29 cysts showed histopathology identical to muscle REBI cysts in praziquantel-treated pigs compared to the 4.3% of 47 cysts in untreated pigs. Closer examination of REBI infiltrates showed that EB was taken up only by eosinophils, a major component of the cellular infiltrates, which likely explains persistence of EB in the REBI. REBI likely represent early damaging host responses to T. solium cysts and highlight the focal nature of this initial host response and the importance of eosinophils at sites of host-parasite interaction. These findings suggest new avenues for immunomodulation to reduce inflammatory side effects of anthelmintic therapy.Cysticidal drug treatment of viable  Taenia solium. Although cysts can be found anywhere in the body, they develop mostly in the muscles, subcutaneous tissues, and brain. Almost all the symptoms in humans, most commonly seizures, are the consequence of involvement of the brain Neurocysticercosis (NCC) is an infection of the central nervous system with metacestodes (cysts) of the cestode Viable cysts in the brain show little or no pericystic inflammation. However, the host begins to react to the degenerating cyst during the natural course of the infection or as a result of anthelmintic treatment, and an intense inflammation commonly ensues T. solium and infection results in cysts that commonly develop in the brain and muscle, similar to human infections. Pigs and humans have similar histopathological changes in brain and muscle, indicative of parasite damage and inflammatory response surrounding the cyst The pig is the natural intermediate host of T. solium infected pigs and cysts of other species of cestodes used in animal model infections T. solium cysts, their histological equivalents in encapsulated brain cysts, their association with praziquantel treatment and the why REBI are dyed with EB.Pericystic inflammation is characteristic of the host response to degenerating cysts in Detection and analysis of cysts containing REBI was performed as part of a study described earlier of the usefulness of injecting the dye to delineate BBB dysfunction in treated and untreated pigs. The methods employed for treatment, EB injection, treatment and collection of samples have been reported Three subsets of specimens were collected shortly after necropsy: non-encapsulated muscle cysts, encapsulated muscle cysts and encapsulated brain cysts; the term capsule refers to pericystic tissue composed by host inflammatory cells, collagen and blood vessels. All specimens destined for histopathological studies were immediately fixed in 10% neutral buffered formalin  for 24–30 hr and paraffin-embedded for sectioning. Serial sections (4 µm in thickness) were mounted on poly-L-Lysine-coated slides  and stained with hematoxylin and eosin (H&E) as well as Masson's trichrome stain for histological analysis. Slides were examined with a light microscope  and photographed with a calibrated camera  using AxioVision software . Encapsulated muscle and brain cysts were classified by gross examination as clear or EB dyed.Some non encapsulated muscle cysts, excised after EB injection and necropsy, exhibited one or more clearly visible small, round foci of superficial EB infiltrated regions (REBI). These cysts, devoid of the capsular host tissue, were selected and processed as above to define the histological characteristics of the focally stained areas.Since gross identification of a cyst with REBI is not possible when the cyst surface is obscured from view by a capsule, a histological approach was taken to determine the capsular inflammation associated with these regions. For this, 10 muscle cysts in paraffin blocks with diffuse EB stained capsules and a limited region in the cyst wall suggestive of REBI were examined histologically to determine the presence of REBI and the capsular inflammation associated with these regions. As a rule, 50 serial sections, which included the entire encapsulated cyst, were examined; three cysts were identified that showed histopathology identical to REBI. To identify brain cysts with identical histopathogy to REBI, every encapsulated brain cyst was serially sectioned.An adaptation of a previously reported scheme for grading cellular infiltrates and cyst wall damage was used to characterize the extent of the inflammatory infiltrates and cyst destruction associated with REBI The cells responsible for EB uptake that constituted REBI were investigated taking advantage of the light EB presence in REBI in deparaffinized, unstained sections, as observed by bright field microscopy, and red autofluorescence of EB The frequencies of cysts with REBI were compared between groups with the Fisher's exact and Chi-square tests. Differences with p-values≤0.05 were considered statistically significant. Statistical analyses were performed using Stata 11 .Taenia solium”, with Dr. Armando Gonzalez as principal investigator. The study protocol was approved by the Animal Ethics and Wellbeing Committee of the University. The Laboratory Animal Care and Use Guidelines on Training is registered with the National Institutes of Health and follows their guidelines. In addition it follows the guidelines of the Royal Society for the Prevention and Cruelty to Animals, the British Veterinary Association, the Fund for Replacement of Animals in Medical Experiments, the Universities Federation for Animal Welfare and Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research. The study was registered with both Universidad Peruana Cayetano Heredia and Universidad Nacional Mayor de San Marcos.Animal experiments were performed at the Facultad de Medicina Veterinaria, Universidad Nacional Mayor de San Marcos, Lima, Peru, under the protocol “Evaluación de la permeabilidad vascular en cerebro y músculo de cerdos naturalmente infectados con T. solium and anthelmintic treatment in pigs While investigating the association between disruption of the BBB and inflammation due to infection by The proportion of REBI in muscle cysts was determined by inspecting all the harvested cysts from only the right hind leg. REBI containing cysts were detected in the muscles in 6 of 8 infected pigs assessed; in three pigs muscle cysts were not evaluated. Six of 3172 cysts (0.2%) from untreated pigs had REBI, whereas the corresponding frequencies of REBI in cysts from PZQ-treated pigs were 126 of 2750 cysts (4.6%) from the PZQ48 group and 119 of 986 cysts (12.1%) in the PZQ120 group, both of which were significantly higher . Among the treated groups (those studied at 48 h and 120 h post-treatment), the proportion of cysts was higher at 120 hr compared to 48 hr  . These dNon-encapsulated muscle cysts with REBI were sectioned through the involved regions for histological examination to characterize the pathological changes associated with the BBB disruption represented by the REBI. H&E staining revealed that REBI co-localized to focal regions of inflammatory infiltrate of varied intensities that penetrated the cyst wall . CellulaSerial sections of deparaffinized, unstained REBI in non encapsulated muscle cysts were examined under light and fluorescence microscopy to identify and co-localize EB with the cells involved in EB uptake. A subpopulation of inflammatory cells in REBI demonstrated a light blue cytoplasm  and exhiREBI were evident in non-encapsulated muscle cysts only because their capsules had been stripped away in the process of collecting cysts. Therefore, the histopathology of the capsule contiguous to REBI could not be directly evaluated. However, systematic sequential sectioning see  and histAll 151 encapsulated brain cysts were processed and analyzed . None ofMore encapsulated cysts with REBI histopathology were found in the brains of the PZQ120 group than in the UT (p<0.005) and PZQ48 group (p<0.01). The number of cysts with REBI histopathology was not statistically different in the PZQ48 group compared to the number in the untreated group, but the number of cysts with REBI histopathology was significantly higher in all treated than in untreated pigs p<0.05; .The capsules of the 8 brain cysts with REBI histopathology showed focal regions of very intense inflammation extending into the wall and body of the cyst at the inflammatory site, which was the only part of the parasite affected . ContiguSerial sections of both brain and muscle encapsulated cysts with REBI histopathology confirmed that the cyst wall outside the involved regions was normal, lacked inflammatory cells and was undamaged, while the surrounding capsules demonstrated varying degrees of inflammation.The identification of the EB-containing cells in encapsulated brain cysts with REBI histopathology was performed in the same way as for REBI characterized in non- encapsulated muscle cysts. Similar to the muscle cysts with REBI, encapsulated brain cysts with REBI histopathology also had blue dyeing in a proportion of the cells indicating uptake of EB . FurtherEosinophils that had taken up EB were present in capsules with a broad range of inflammatory responses but, in general, the proportion of eosinophils increased as the inflammation score went from moderate  to intenT. solium cysts, which we found are circumscribed regions of BBB disruption associated with inflammatory responses. Furthermore, regions with identical histopathology were identified in encapsulated muscle and brain cysts.The major findings of this work are recognition, description and characterization of focal regions of Evans blue infiltration (REBI) on the surface of Although previous studies examined untreated and treated pigs and described focal eosinophilic-rich inflammation directed to cysts As noted above, REBI are sites of an early effective, damaging host response to the cyst. We can base this conclusion on a number of features of the REBI. Firstly, the inflammation associated with the REBI is limited to small focal, circumscribed region(s) on the tegument of affected cysts and contrasts with the general inflammatory response seen in the majority of degenerating cysts. Secondly, the frequency of cysts with REBI increases following praziquantel treatment, which triggers inflammatory responses to viable cysts. Thirdly, the timing of the appearance of REBI at 5 days is similar to the time frame in which humans develop symptoms/seizures following initiation of treatment, generally occurring within the first week post-treatment. The number of REBI cysts is a minority of the total number of cysts; one reason for the low frequency may be because the cysts were sampled at one point in time in the course of an evolving process, which may not be the optimal time for the development of REBI in all cysts. Another potential reason for the low frequency of REBI could be the relatively low efficacy of a single dose of praziquantel – only a proportion of cysts may have been damaged of killed. Whether REBI represent the only initial or early response or a special type of response can only be ascertained through prospective analysis of cysts in treated animals over an extended period of time.REBI can only be directly visualized on cysts devoid of their capsules; our initial discovery of REBI containing cysts occurred in the process of harvesting muscle cysts extruded from their capsules for other experiments The inflammatory response in swine with NCC has been described by a number of investigators T. solium capsules may also be activated, leading to albumin ingestion along with EB. Other molecules that are carried by albumin may also be important in facilitating uptake of EB. Why some eosinophils take up EB and some do not is unclear but may have to do with factors such as differing activation states of eosinophils in REBI at the time of EB injection.Eosinophils predominate in these inflammatory infiltrates , 2I, at Since our methods are not sufficiently quantitative to determine the amount of EB present in tissues, we cannot determine the contribution of eosinophil uptake to total EB staining. However, a notable observation was that we did not find other cells containing EB, nor did we see extracellular EB or EB near vessels, which might be expected after disruption of the vascular barrier. Also, we found no evidence that the wall of the cyst itself was dyed with EB. Thus, the uptake of EB was predominantly, if not exclusively, by eosinophils.T. solium cysts in pig muscles Schistosoma mansoni and S. haematobium, Eosinophils are known to play an essential role in the cytotoxic response to helminth parasites and were identified in the inflammatory infiltrate around viable In humans, cysticidal treatment incites an intense inflammation as noted clinically by seizures and the new appearance of pericystic edema and enhancement


The cytolethal distending toxin (Cdt) is a heterotrimeric holotoxin produced by a diverse group of Gram-negative pathogenic bacteria. The Cdts expressed by the members of this group comprise a subclass of the AB toxin superfamily. Some AB toxins have hijacked the retrograde transport pathway, carried out by the Golgi apparatus and endoplasmic reticulum (ER), to translocate to cytosolic targets. Those toxins have been used as tools to decipher the roles of the Golgi and ER in intracellular transport and to develop medically useful delivery reagents. In comparison to the other AB toxins, the Cdt exhibits unique properties, such as translocation to the nucleus, that present specific challenges in understanding the precise molecular details of the trafficking pathway in mammalian cells. The purpose of this review is to present current information about the mechanisms of uptake and translocation of the Cdt in relation to standard concepts of endocytosis and retrograde transport. Studies of the Cdt intoxication process to date have led to the discovery of new translocation pathways and components and most likely will continue to reveal unknown features about the mechanisms by which bacterial proteins target the mammalian cell nucleus. Insight gained from these studies has the potential to contribute to the development of novel therapeutic strategies. Representative examples include: Aggregatibacter actinomycetemcomitans (AaCdt); Campylobacterjejuni (CjCdt); Escherichia coli ; Haemophilius ducreyi (HdCdt); Helicobacterhepaticus (HhCdt); Providencia alcalifaciens (PaCdt); Shigella boydii (SbCdt) and Shigella dysenteriae (SdCdt)  and Javiana (SejCdt), carry only the cdtB gene and employ alternative strategies to intoxicate susceptible target cells .

There are five general groups of retrograde cargoes: (i) cargo sorting receptors; (ii) integral membrane proteases; (iii) SNAREs  [Delivery of protein toxins from endosomes to the Golgi apparatus is a common process but is not as clearly understood as endocytosis. Toxin trafficking takes advantage of the secretory pathways of the cell which function in the routine enzymatic modification and distribution of secretory cargo to organelles and the extracellular space. Cargo is either earmarked for degradation in the lysosomal degradation pathway or recycling in the retrograde pathway.

The endosome contains vacuolar and tubular domains. The tubular endosomal network (TEN) is part of the TGN that represents the last Golgi cisternae and is the primary sorting structure of the retrograde pathway because it contains a relatively high degree of membrane curvature and low lumenal volume ,59. ThesHdCdtB subunit undergoes retrograde transport. Based on the results of experiments using Brefeldin A, a well-known inhibitor of the transport of proteins between the ER and the Golgi apparatus, it was found that an intact Golgi complex is required for cell intoxication by the HdCdt and EcCdt [HdCdtB, modified to contain a sulfation site, was labeled with 35S following the intoxication of cells grown in the presence of Na235SO4.

TPseudomonas exotoxin A, the study of Cdt translocation is in its infancy. Part of the challenge in elucidating the precise molecular details of Cdt trafficking is the unique aspects of this subclass of AB toxins. Unique properties exhibited by some or all of the species-specific Cdts are translocation by a late endosomal pathway, ER processing possibly by an atypical non-ERAD pathway and directed transport to the nucleus due to the presence of an atypical NLS sequence. Conclusions based on the results of multiple independent investigations suggest that the various species-specific Cdts require different membrane receptors, interact differently with membrane lipids, exhibit different target cell specificities and inhibit different cell pathways thereby further complicating efforts to elucidate the details of toxin trafficking. It is well established that toxins supply versatile tools for probing the complex functions of the Golgi apparatus and ER [Retrograde transport of toxins via the Golgi apparatus and ER requires a complex cascade of supporting protein chaperones, protein complexes, small GTPases and unidentified components. The process is complicated further by observations that various toxins have evolved to hijack different components of the TGN and ER protein processing machinery.

To date, choroidal blood flow reduction in highly myopic eyes appears to be related to the development of choroidal neovascularization secondary to local reduction of arterial flow. Instead, no evidence of choroidal neovascularization was found in subjects with low or moderate myopia. The authors' aim has been to encourage new studies regarding the potential role of chronic retinal venous congestion in the pathogenesis of choroidal neovascularization. In December 2011, a 54-year-old woman with moderate bilateral myopia had a sudden block upon swallowing while she was eating. Subsequently (January 2013) metamorphopsia in the left eye revealed macular degeneration with choroidal neovascularization. The related echo-color Doppler study of the neck veins, performed in November 2014, showed an atypical left jugular insufficiency associated with homolateral hypertension of the superior ophthalmic veins. This singular case highlights the necessity to further investigate the potential role of chronic alterations of intra- and extracranial venous drainage in the disruption of choroidal flow in myopic patients. Maculopathy is one of the most important complications of myopia; the severity of this condition is associated with increased axial length and increased age . LikewisIn December 2011 a 54-year-old woman, suffering from a bilateral spherical equivalent refraction of −5.2 diopters, experienced a violent pain in the jugular notch that was transmitted to the head, after an episode of a sudden block upon swallowing, while she was eating. Since this episode, she experiences pain while coughing and generally with every Valsalva maneuver. In January 2013, metamorphopsia in the left eye revealed macular degeneration with CNV. Optical coherence tomography (OCT) best describes the situation Figures  and 2.http://dx.doi.org/10.1155/2015/960950).A magnetic resonance imaging of the head and a neurological assessment were performed with negative results. In November 2014, she was brought to our attention to assess her intra- and extracranial venous vessels. ECD evaluation of neck veins in the supine position revealed atypical anterior jugular veins (AJVs) of increased size with normal valve leaflets in the proximal segment of the right vein and incontinence on the left side. The right AJV exhibited normal behavior during the Valsalva maneuver with temporary blocking of the outflow, whereas the left AJV revealed significant reflux from the confluence with the subclavian vein to the distal segment (J3) of the IJV through the anterior and common facial veins   through the AFV and the nasofrontal vein. In the sitting position, we only observed the reflux during the Valsalva maneuver, involving the proximal segment of the left AJV. The transcranial approach through the supracondylar window revealed spontaneous reflux in the left inferior petrosal sinus in the supine and sitting positions .We believe this case report is interesting because it focuses on the potential role of chronic retinal venous congestion related to the impairment of extracranial outflow in the pathogenesis of CNV. To date, studies have focused on extrinsic mechanisms involved in CNV, such as the excessive elongation of the eyeball in patients with high myopia, thereby stretching the choroid, reducing arterial flow due to the increase in vascular resistance, and resulting in the release of vascular endothelial growth factor (VEGF) , 4. SimiLeft and right anterior jugular veins (AJV) during a normal breathing and at Valsalva manoeuvre. The right vein shows a normal outflow with temporary blocked flow during the Valsalva. Along the left vein we see a spontaneous reflux during the normal breathing with a massive increase evoked from the Valsalva also interesting the homolateral anterior facial vein ( L AFV).


Improved gait efficiency is one of the goals of therapy for children with cerebralpalsy (CP). Postural insoles can allow more efficient gait by improvingbiomechanical alignment. The aim of the present study was to determine the effect of the combination ofpostural insoles and ankle-foot orthoses on static and functional balance inchildren with CP. A randomized, controlled, double-blind, clinical trial. After meeting legalrequirements and the eligibility criteria, 20 children between four and 12 yearsof age were randomly allocated either to the control group (CG) (n=10) or theexperimental group (EG) (n=10). The CG used placebo insoles and the EG usedpostural insoles. The Berg Balance Scale, Timed Up-and-Go Test, Six-Minute WalkTest, and Gross Motor Function Measure-88 were used to assess balance as well asthe determination of oscillations from the center of pressure in theanteroposterior and mediolateral directions with eyes open and closed. Threeevaluations were carried out: 1) immediately following placement of the insoles;2) after three months of insole use; and 3) one month after suspending insole use.The EG achieved significantly better results in comparison to the CG on the TimedUp-and-Go Test as well as body sway in the anteroposterior and mediolateraldirections. Postural insoles led to an improvement in static balance among children withcerebral palsy, as demonstrated by the reduction in body sway in theanteroposterior and mediolateral directions. Postural insole use also led to abetter performance on the Timed Up-and-Go Test. Maintaining thecenter of gravity of the body over the support base is a complex skill. The clinicalstate of CP includes neuromuscular deficits, such as the loss of selective motor controland changes in muscle tone, leading to an imbalance between agonist and antagonistmuscles, compromised coordination, sensory abnormalities, and muscle weaknessStudies are currently underway to determine whether postural insoles can produce similareffects to those achieved with ankle-foot orthoses. The findings suggest that posturalinsoles are capable of reorganizing the tonus of muscle chains and exerting an influenceon postural control through correction reflexes, thereby acting on muscle proprioceptionand resulting in changes in the ascending proprioceptive chainsThe aim of the present study was to determine the effect of the combination of posturalinsoles and ankle-foot orthoses on static and functional balance in children withCP.This study received approval from the Human Research Ethics Committee of UniversidadeNove de Juho (UNINOVE), São Paulo, SP, Brazil under protocol number 436960 and wascarried out in compliance with Resolution 196/96 of the Brazilian National Board ofHealth. The study is registered with Registro Brasileiro de ensaios clínicos - REBECunder process number RBR6d342s (ensaiosclinicos.gov.br). The legal guardians agreed tothe participation of the children by signing a statement of informed consent. Aprospective, analytical, randomized, controlled, double-blind, clinical trial wasconducted in the Movement Analysis Laboratory, UNINOVE .Individuals with CP were recruited from the physical therapy clinics of UNINOVE, Brazil.There were no important changes to the methods after trial commencement. Among the 33children recruited for the present study, ten did not fulfill the eligibility criteriaand three refused to participate. Thus, the sample was made up of 20 children with CP,ten of whom were randomly allocated to the control group (CG) and ten to theexperimental group (EG).The inclusion criteria were a diagnosis of spastic diplegic CP and classification aslevels of I or II of the Gross Motor Function Classification System (GMFCS)The exclusion criteria were as follows: surgical procedures or the administration ofphenol in the previous 12 months; neurolytic block in the previous six months; cognitiveor visual impairment that could have interfered with the performance of the procedures;and ankle deformities that were non-reducible to neutral.The primary outcome was oscillations in the center of pressure (COP). As no previousstudies were found on the effects of proprioceptive postural insoles on body sway,the sample size was calculated based on a study in which the effect of ankle-footorthoses on body sway was investigated. Roque et al.The participants were randomly allocated to the different groups using cards enclosedin sequentially numbered opaque envelopes. This process was carried out by a memberof the team who was not involved in the recruitment process or development of thestudy. The control group (CG) wore insoles without corrective elements (placeboinsoles) and the experimental group (EG) wore insoles with corrective elements. Thus, the conditions for a blind study for the placebo effect ofthe insole in the CG were satisfied. The examiners and guardians were unaware of thedifferences between the two types of insole and were blinded to the allocation of thechildren to the different groups.-,,The following standardized assessment tools were used for the evaluation of balanceand functional mobility at baseline and after three months of insole use: BergBalance Scale-The Berg Balance Scale (BBS) consists of 14 items that simulate activities of dailyliving. Each item receives a score ranging from zero (inability to perform taskwithout assistance) to 4 (ability to perform task independently). The total rangesfrom 0 to 56 points, with higher scores denoting greater independence,The Timed Up-and-Go Test (TUG) quantifies functional mobility by the time (inseconds) required for a child to stand up from a standardized chair with arm rests,walk three meters, turn around, return to the chair, and sit down again,The Six-Minute Walk Test is a reliable measure for the assessment of physical fitnessand functional mobility that quantifies the distance (in meters) an individualtravels in six minutes. This test was performed based on the recommendationsestablished by the American Thoracic SocietyThe GMFM-88 is a measure used to quantify gross motor function in individuals withCP. The test consists of observational measures that evaluate motor function throughitems distributed among six dimensions: A) lying down and rolling; B) sitting; C)crawling and kneeling; D) standing; and E) walking, running, and jumping. The itemsin each dimension receive a score of 0 to 3 points, with higher scores denotingbetter performanceStatic balance was evaluated using a force plate , whichallows stabilometric analysis through the recording of oscillations in the COP. Thesampling frequency was 50 Hz captured by four piezoelectric sensors located at theextremities of the platform (400 × 600 mm). The data were recorded and interpretedusing the SWAY program (BTS Engineering) and all data were processed using theSMART-D program (BTS Engineering). This system constitutes a board that integratesthe capture and analysis programs regarding kinetic data ,kinematic data, and electromyographic data. Thus, all the data are synchronized. Forthe evaluation of static balance, the child was instructed to remain in a quietstanding position on the platform with arms alongside the body, gaze fixed on a pointmarked at a distance of one meter at the height of the glabellum, with anunrestricted foot base, and heels in alignment. The foot base was unrestrictedbecause the distance between the feet was not standardized based on height, age, andfoot size. Readings were made under three conditions: 1) barefoot; 2) in shoeswithout insoles; and 3) in shoes with insoles . Underall three conditions, the children were evaluated with eyes open and eyes closed.Evaluations took place on two occasions: immediately after placement of the insolesand after three months of insole use. The order of the different conditions wasdetermined randomly to avoid normalization of the behavior of the sample. Under eachcondition, displacement from the COP was determined on the x (anteroposterior) and y axes.. Postural insoles arecomposed of three layers. The aim of the surface layer is to absorb perspiration andprovide comfort. The middle portion is made up of ethylene-vinyl acetate measuring 3mm in thickness. The lower portion is made up of material formed by cotton fibers andresin measuring 1 mm in thickness and contains shims and wedges made ofethylene-vinyl acetateThe insoles were prepared by a physical therapist in the city of Sorocaba, SP,Brazil, who used the base insoles and corrective elements fabricated by Podaly(r)The Kolmogorov-Smirnov test demonstrated normal data distribution. Thus, parametrictests were performed, and the data were expressed as mean and standard deviation.Two-way ANOVA with the Bonferroni post-hoc test was used to compare the effects ofinsole use on functional mobility . The dependent variable wasthe distance travelled on the test and the fixed independent variables were insole(barefoot and insole), group (EG and CG), and group-treatment interactions. Similarmodels were run for the other variables. The effect size was calculated consideringthe mean difference between evaluation times  and groups (EG vs. CG). A p-value <0.05 indicateda statistically significant result. The data were organized and tabulated using theStatistical Package for Social Sciences (v.19.0).The inter-group analysis demonstrated no significant differences immediately followingthe placement of the postural insoles with corrective elements in the EG and placeboinsoles without corrective elements in the CG, with the exception of the shorter timerequired to execute the TUGT in the EG. In the intra-group analysis, no significantdifferences were found in either group immediately after placement of the insoles.During the evaluations conducted after three months of insole use, no significantdifferences were found in any of the variables in either group in the comparison of thebarefoot and shoes + insoles conditions, demonstrating that the performance of thechildren was similar with and without insoles after three months of insole use for sixhours per day. In the intra-group analysis, the EG demonstrated significant reductionsin the time required to execute the TUGT as well as in body sway in the anteroposteriorand mediolateral directions with eyes open. No significant differences in any othervariables were found in the EG and no differences were found in any of the variables inthe CG after three months of insole use.When intragroup analysis was performed considering the three conditions , significant differences were only found in theEG group on the TUGT  andanteroposterior sway with eyes closed .Changes in balance and functional mobility are important to the rehabilitation ofchildren with CP. The present findings suggest that postural insoles lead toimprovements in static balance and mobility and contribute toward a better understandingand integration of therapeutic resources employed in physical rehabilitation applied topediatric neurology.Children with CP exhibit delayed development in terms of balance and stability incomparison to normal children. According to Liao and HwangThere are no previous studies on improvements in balance and functional mobility inpatients with CP following the use of proprioceptive insoles. However, a number ofstudies have demonstrated the benefits of such insoles in terms of other aspects.Palluel et al.The present findings suggest that postural insoles cause a change in sensorialafference, stimulating a postural reaction that favors a better biomechanical alignmentof the body and permits more efficient function, especially with regard to balance. Oneof the hypotheses for this improvement is supported by the findings described by Ceci etal.Gan et al.Nobre et al.Postural insoles led to an improvement in static balance among children with cerebralpalsy, as demonstrated by the reduction in body sway in the anteroposterior andmediolateral directions. The use of postural insoles also led to improved performance onthe Timed Up-and-Go Test.
