Chronic kidney disease is becoming a global public health problem, which will usually cause uremia at the end stage of chronic kidney failure. So far, kidney transplant is the most effective and proper therapy for uremia, however, the short supply of matched donor kidney has been a persistent bottleneck for transplantation. HLA matching of HLA-A, -B and -DRB1 loci is very important for the allocation of kidney transplants. In this study, we investigated genotypes of HLA-A, -B and -DRB1 loci based on 1,464 uremia patients and 10,000 unrelated healthy individuals in Henan province of China, and compared the frequency distribution of these HLA alleles and corresponding haplotypes between patient and healthy groups...

The regionally endemic Galapagos Grouper, locally known as bacalao, is one of the most highly prized finfish species within the Galapagos Marine Reserve (GMR). Concerns of overfishing, coupled with a lack of fishing regulations aimed at this species raises concerns about the current population health. We assessed changes in population health over a 30-year period using three simple indicators: (1) percentage of fish below reproductive size (Lm); (2) percentage of fish within the optimum length interval (Lopt); and (3) percentage of mega-spawners in the catch...

Millions suffer from chronic vulvar pain (ie, vulvodynia). Vulvodynia represents the intersection of 2 difficult subjects for health care professionals to tackle: sexuality and chronic pain. Those with chronic vulvar pain are often uncomfortable seeking help, and many who do so fail to receive proper diagnoses. The current research developed a multidimensional assessment questionnaire, the Vulvar Pain Assessment Questionnaire (VPAQ) inventory, to assist in the assessment and diagnosis of those with vulvar pain...

BACKGROUND: Ciprofloxacin is a synthetic broad-spectrum antimicrobial agent of fluoroquinolone family. The aim of our investigation was to evaluate the role of oxidative damage and inflammation in nephrotoxic potential of Ciprofloxacin and protective effects of melatonin against its nephrotoxicity in male Wistar rats. METHODS: The animals were divided into six groups: Control, ciprofloxacin (100mg/kg/day, i.p), ciprofloxacin with three doses (2.5, 5 and 10mg/kg/day) of melatonin and a group which received ciprofloxacin (100mg/kg/day) plus vitamin E (100mg/kg/day) for 8 consecutive days...

BACKGROUND: Compensation for participating in research has been a fundamental element of the research apparatus despite concerns about its impact on incentivising participation. Researchers and research ethics boards acknowledge that compensation may prompt structurally vulnerable populations, such as people who use drugs (PWUD), to engage in research primarily out of financial need. Thus, institutional restrictions around compensation have been implemented. This study explores the ethical implications of compensation practices aimed at 'protecting' structurally vulnerable people living with HIV (PLHIV) who use drugs within the context of individuals' lived realities...

Some organic pollutants including polychlorinated biphenyls (PCBs), polybrominated diphenylethers (PBDEs) and hexachlorobenzene (HCB) have been banned from production and use in the UK for >30years but due to their toxicity and persistence are still of concern. However, due to their hydrophobicity they are present at very low concentrations and are difficult to measure in water, and so other matrices need to be sampled in order to best assess contamination. This study measured concentrations of ΣICES 7 PCBs (PCB congeners 28, 52, 101, 118, 138, 153 and 180) and Σ6 PBDEs (PBDE congeners 28, 47, 99, 100, 153, 154) and HCB in both bed-sediments and wild roach (a common pelagic fish) in the Thames Basin...

Abandoned and flooded mine networks provide underground reservoirs of mine water that can be used as a renewable geothermal energy source. A complete hydrochemical characterization of mine water is required to optimally design the geothermal installation, understand the hydraulic behavior of the water in the reservoir and prevent undesired effects such as pipe clogging via mineral precipitation. Water pumped from the Barredo-Figaredo mining reservoir (Asturias, NW Spain), which is currently exploited for geothermal use, has been studied and compared to water from a separate, nearby mountain mine and a river that receives mine water discharge and partially infiltrates into the mine workings...

Chemical speciation, reactivity, and bioavailability of trace metals in aqueous systems arestrongly influenced by dissolved organic matter (DOM). DOM is a mixture of diverse components, so a range of organic molecules potentially participates in the occurrence of dissolved trace metals. In this study, we investigated water quality variables that influence dissolved trace metal concentrations in natural and effluent water systems with a particular attention given to the relationship between DOM optical properties and dissolved copper and iron concentrations...

The world's leading environmental advisory institutions look to ecological theory and research as an objective guide for policy and resource management decision-making. In addition to the theoretical and broadly philosophical merits of doing so, it is therefore practically significant to clear up confusions about ecology's conceptual foundations and to clarify the basic workings of inferential methods used in the science. Through discussion of key moments in the genesis of the theoretical branch of ecology, this essay elucidates a general heuristic role of teleological metaphors in ecological research and defuses certain enduring confusions about work in ecology...

INTRODUCTION: HPV attributable cancers are the second most common infection-related cancers worldwide, with much higher burden in less developed regions. There are currently no country-specific estimates of the burden of these cancers in Nigeria just like many other low and middle income countries. METHODS: In this study, we quantified the proportion of the cancer burden in Nigeria that is attributable to HPV infection from 2012 to 2014 using HPV prevalence estimated from previous studies and data from two population based cancer registries (PBCR) in Nigeria...

When an esteemed elderly colleague needs assistance completing procedures safely, fellow health professionals have the responsibility to respond in order to mitigate risk to patients. There is a strong ethical basis for bringing the surgeon's declining capacity to his or her attention as well as to the attention of others. Ongoing capacity assessments could be one method for tracking diminished capacities among surgeons so that they can stop practicing surgery before putting patients at risk.

Though conventionally not considered standard of care, nonoperative management of patients with small bowel obstruction (SBO) without previous abdominal operations, so called "virgin abdomens," (VA) is presently being practiced. We aimed to determine outcomes of patients with VA undergoing operative and nonoperative management of SBO. A retrospective review of patients with SBO was performed; outcomes of patients with VA were analyzed. SBO with a VA was found in 103 patients over a 5-year period. With a mean follow-up of 4...

Excessively choosing immediate over larger future rewards, or delay discounting (DD), associates with multiple clinical conditions. Individual differences in DD likely depend on variations in the activation of and functional interactions between networks, representing possible endophenotypes for associated disorders, including alcohol use disorders. Numerous fMRI studies have probed the neural bases of DD, but investigations of large-scale networks remain scant. We addressed this gap by testing whether activation within large-scale networks during Now/Later decision-making predicts individual differences in DD...

Tropical cyclones can significantly damage the electrical power system, so an accurate spatiotemporal forecast of outages prior to landfall can help utilities to optimize the power restoration process. The purpose of this article is to enhance the predictive accuracy of the Spatially Generalized Hurricane Outage Prediction Model (SGHOPM) developed by Guikema et al. (2014). In this version of the SGHOPM, we introduce a new two-step prediction procedure and increase the number of predictor variables. The first model step predicts whether or not outages will occur in each location and the second step predicts the number of outages...

Acetylcholine (ACh) released at the vertebrate nerve-muscle synapse is hydrolyzed rapidly into choline (Cho), so endplate receptors (AChRs) are exposed to high concentrations of both of these structurally-related ligands. To understand how these receptors distinguish ACh and Cho, we used single-channel electrophysiology to measure resting affinities (binding free energies) of these and other agonists in adult-type mouse AChRs having a mutation(s) at the transmitter-binding sites. The aromatic rings of αY190, αW149 and αY198 each provide ∼50% less binding energy for Cho compared to ACh...

A small (7-11 μm long), dinoflagellate with thin amphiesmal plates was isolated into culture from a water sample collected in coastal waters off Yeosu, southern Korea, and examined by LM, SEM, and TEM, and molecular analyses. The hemispheric episome was smaller than the hyposome. The nucleus was oval and situated from the central to the episomal region of the cell. A large yellowish-brown chloroplast was located at the end of the hyposome, and some small chloroplasts extended into the periphery of the episome...
