Todos os Santos Bay (BTS) is the 2nd largest bay in Brazil and an important resource for the people of the State of Bahia. We made measurements of radon and radium in selected areas of the bay to evaluate if these tracers could provide estimates of submarine groundwater discharge (SGD) and flushing times of the Paraguaçu Estuary and BTS. We found that there were a few areas along the eastern and northeastern shorelines that displayed relatively high radon and low salinities, indicating possible sites of enhanced SGD...

BACKGROUND: Continuous renal replacement therapies (CRRTs) either as continuous venovenous hemofiltration (CVVH) or hemodiafiltration (CVVHD) are used frequently in critically ill children. Many clinical variables and technical issues are known to affect the result. The factors that could be modified to increase the survival of renal replacement are sought. As a contribution, we present the data on 104 patients who underwent CRRT within a 7-year period. MATERIALS AND METHOD: A total of 104 patients admitted between 2009 and 2016 were included in the study...

We reviewed advances in therapeutics for both Friedreich ataxia and Machado-Joseph disease. Various clinical trials have been carried out, mainly for Friedreich ataxia; however, the therapeutic reports from these trials have not provided much evidence for success. Some interesting clinical trials have been reported, and further developments are expected. Regenerative therapy using umbilical cord mesenchymal stem cells and a therapeutic study investigating a new pathomechanism in animal and/or cell culture studies were reported...

Molecular techniques are widely used in the field of parasitology to identify the genetic profile of the microbiological agents. Microsatellite typing studies are comprised of the amplification of polymorphic markers to analyze the fragment sizes using bioinformatics tools. Current methods need fluorescently labeled primers and size markers to obtain fragment peaks in ABI PRISM® systems and due to low discrimination power of gel-electrophoresis, it is not possible to differentiate primer-dimers from small fragments In the present study, we designed a new method for fragment analysis studies, which reduce the time by eliminating the classical PCR, the gel-electrophoresis and the preparation steps of fragment analysis...

INTRODUCTION: Measuring unlabeled ligand receptor binding kinetics is valuable in optimizing and understanding drug action. Unfortunately, deriving equations for estimating kinetic parameters is challenging because it involves calculus; integration can be a frustrating barrier to the pharmacologist seeking to measure simple rate parameters. Here, a well-known tool for simplifying the derivation, the Laplace transform, is applied to models of receptor-ligand interaction. The method transforms differential equations to a form in which simple algebra can be applied to solve for the variable of interest, for example the concentration of ligand-bound receptor...

Unilateral spatial neglect is a neuropsychological syndrome often observed in right hemisphere stroke patients. The symptoms differ from subject to subject. A few rehabilitation approaches, e.g. prism adaptation, have demonstrated some effect in reducing the symptoms, but the underlying mechanisms are still largely unclear. Recently, neural models have been proposed to qualitatively describe cortical lesions, the resulting neglect symptoms and the effects of treatment. However, these predictions are qualitative and cannot be used to compare different hypotheses or to interpret symptoms at individual subjects level...

BACKGROUND: Speckle-type POZ protein (SPOP) is an E3 ubiquitin ligase adaptor protein that functions as a potential tumor suppressor, and SPOP mutations have been identified in ~10% of human prostate cancers. However, it remains unclear if mutant SPOP proteins can be utilized as biomarkers for early detection, diagnosis, prognosis or targeted therapy of prostate cancer. Moreover, the SPOP mutation sites are distributed in a relatively short region with multiple lysine residues, posing significant challenges for bottom-up proteomics analysis of the SPOP mutations...

#10
Steven D Collins, John C Abbott, Nancy E McIntyre
Citizen-science databases have been used to develop species distribution models (SDMs), although many taxa may be only georeferenced to county. It is tacitly assumed that SDMs built from county-scale data should be less precise than those built with more accurate localities, but the extent of the bias is currently unknown. Our aims in this study were to illustrate the effects of using county-scale data on the spatial extent and accuracy of SDMs relative to true locality data and to compare potential compensatory methods (including increased sample size and using overall county environmental averages rather than point locality environmental data)...

CONTEXT: Kidney transplantation from donors with expanded criteria has increased the pool of kidneys at the cost of a higher risk of short and long-term graft dysfunction. The main issue lies in determining which kidneys will offer acceptable function and survival compared with the risk represented by surgery and subsequent immunosuppression. OBJECTIVE: The objective of our article is to review the current evidence on the tools for predicting the functionality of kidney transplantation from cadaveric donors with expanded criteria and determining the validity for their use in standard practice...

Bimetallic hollow, porous noble metal nanoparticles are of broad interest for biomedical, optical and catalytic applications. The most straightforward method for preparing such structures involves the reaction between HAuCl4 and well-formed Ag particles, typically spheres, cubes, or triangular prisms, yet the mechanism underlying their formation is poorly understood at the atomic scale. By combining in situ nanoscopic and atomic-scale characterization techniques (XAFS, SAXS, XRF, and electron microscopy) to follow the process, we elucidate a plausible reaction pathway for the conversion of citrate-capped Ag nanospheres to AgAu nanocages; importantly, the hollowing event cannot be explained by the nanoscale Kirkendall effect, nor by Galvanic exchange alone, two processes that have been previously proposed...

BACKGROUND: The second cause of blindness in the world is glaucoma that begins with visual impairments and, in many cases, ends with irreversible visual loss. Primary open-angle glaucoma (POAG) is the most common type of glaucoma, which causes irreversible optic nerve damage in adults. Glaucoma shows an unknown etiology, but there is strong evidence regarding the role of genetic factors in disease establishment. For determination of the role of MYOC gene mutations in the development of POAG in Zahedan, Iran, screening of this gene was performed...

Radek Ptak
Prism adaptation (PA) has been successfully applied in the rehabilitation of spatial neglect, with significant transfer to classic neglect tests and activities of daily living. However, well-controlled studies were unable to replicate these findings, and recent reports suggest that PA may affect selectively visuo-motor symptoms. Here, a patient with pure left neglect dyslexia was tested before, immediately after, and 24 h after PA. Despite a significant adaptation aftereffect adaptation had no effect omissions, substitutions and letter-based errors...

This study proposes a new type of calcium phosphate (CaP) scaffolds with a continuously gradient macro/microporous structure using the ceramic/camphene-based 3D extrusion process. Green filaments with a continuously gradient core/shell structure were successfully produced by extruding a bilayered feedrod comprised of a CaP/camphene mixture lower part and a pure camphene upper part. The extruded filaments were then deposited in a controlled manner to construct triangular prisms, followed by the assembly process for the production of CaP scaffolds with a gradient core/shell structure...
