Candida Endophthalmitis
submitted by babmellir2059 12 minutes ago - Topic: Health
While Candida causes only 6 % of all culture-positive endophthalmitis cases, the visual consequences of delayed or inappropriate treatment can be devastating. Most cases are endogenous, arising from hematogenous spread during candidemia. These cases manifest either as chorioretinitis alone or also with vitritis. Early infection may be asymptomatic so all candidemic patients should be screened...



Mapping contaminated soils: using remotely-sensed hyperspectral data to predict pH
submitted by orreboso 12 minutes ago - Topic: Agriculture
This study assessed the feasibility of remote mapping and, thus, monitoring of soils contaminated by acid mine drainage. We report on the use of laboratory and airborne spectroscopy to determine pH. Reflectance spectra were obtained for rock and soil samples collected at our test site, the abandoned Brukunga Pyrite Mine in South Australia, using a laboratory-based Analytical Spectral Devices In...

Malaysian weedy rice shows its true stripes: wild Oryza and elite rice cultivars shape agricultural weed evolution in Southeast Asia
submitted by ponyombele 13 minutes ago - Topic: Biology
Weedy rice is a close relative of domesticated rice (Oryza sativa) that competes aggressively with the crop and limits rice productivity worldwide. Most genetic studies of weedy rice have focused on populations in regions where no reproductively compatible wild Oryza species occur (North America, Europe, northern Asia). Here we examined the population genetics of weedy rice in Malaysia, where w...

Ocean circulation model predicts high genetic structure observed in a long-lived pelagic developer
submitted by ponyombele 13 minutes ago - Topic: Biology
Understanding the movement of genes and individuals across marine seascapes is a long-standing challenge in marine ecology, and can inform our understanding of local adaptation, the persistence and movement of populations, and the spatial scale of effective management. Patterns of gene flow in the ocean are often inferred based on population genetic analyses coupled with knowledge of species’...

Human-aided and natural dispersal drive gene flow across the range of an invasive mosquito
submitted by ponyombele 13 minutes ago - Topic: Biology
Human-aided transport is responsible for many contemporary species introductions, yet the contribution of human-aided transport to dispersal within non-native regions is less clear. Understanding dispersal dynamics for invasive species can streamline mitigation efforts by targeting routes that contribute disproportionally to spread. Because of its limited natural dispersal ability, rapid spread...



Novel molecular approach demonstrates turbid river plumes reduce predation mortality on larval fish
submitted by ponyombele 13 minutes ago - Topic: Biology
Turbidity associated with river plumes is known to affect the search ability of visual predators and thus can drive “top-down” impacts on prey populations in complex ecosystems; however, traditional quantification of predator-prey relationships (i.e., stomach content analysis) often fail with larval fish due to rapid digestion rates. Herein, we use novel molecular genetic methods to quantif...

Genomic atolls of differentiation in coral reef fishes (Hypoplectrus spp, Serranidae)
submitted by ponyombele 13 minutes ago - Topic: Biology
Because the vast majority of species are well-diverged, relatively little is known about the genomic architecture of speciation during the early stages of divergence. Species within recent evolutionary radiations are often minimally diverged from a genomic perspective, and therefore provide rare opportunities to address this question. Here, we leverage the hamlet radiation (Hypoplectrus spp, br...


Comparative landscape genetics of two river frog species occurring at different elevations on Mount Kilimanjaro
submitted by ponyombele 13 minutes ago - Topic: Biology
Estimating population connectivity and species’ abilities to disperse across the landscape is crucial for understanding the long-term persistence of species in changing environments. Surprisingly, few landscape genetics studies focused on tropical regions despite the alarming extinction rates within these ecosystems. Here, we compared the influence of landscape features on the distribution of...

Knowledge and attitudes to vitamin D and sun exposure in elite New Zealand athletes: a cross-sectional study
submitted by bibi 13 minutes ago - Topic: Health
Sun safety and vitamin D status are important for prolonged health. They are of particular interest to those working with athletes for whom for whom safe sun practices maybe limited. The aim of this cross-sectional study was to describe the attitudes of elite New Zealand athletes to both vitamin D and sun exposure. 110 elite New Zealand outdoor athletes volunteered to participate in an intervie...


Do physical activity and sedentary behavior relate to cardio-metabolic risk factor clustering in indigenous Siberian adults?
submitted by majtobo3521 14 minutes ago - Topic: Biology
To investigate whether having multiple risk factors for cardio-metabolic disease is associated with objectively measured physical activity or sedentary behavior within a sample of Yakut (Sakha) of Siberia. This cross sectional study involved 63 Yakut adults (32 men) who were measured for cardio-metabolic risk factors. Free living physical activity and sedentary behavior were calculated from wai...

Alleviating climate change impacts in rural Bangladesh: a PROMETHEE outranking-based approach for prioritizing agricultural interventions
submitted by jmgobreil 16 minutes ago - Topic: Environment
This paper presents a PROMETHEE multicriteria outranking-based approach for prioritizing agricultural interventions to alleviate climate change on a farm basis. The drought-prone areas of Rajshahi and flood-saline-prone areas of Barisal in rural Bangladesh were chosen as case studies. A number of existent agricultural interventions have been comparatively evaluated upon several diversified crit...


MicroRNA expression profile in exosome discriminates extremely severe infections from mild infections for hand, foot and mouth disease
submitted by ohjarth 23 minutes ago - Topic: Health
Changes of miRNAs in exosome have been reported in different disease diagnosis and provided as potential biomarkers. In this study, we compared microRNA profile in exosomes in 5 MHFMD and 5 ESHFMD as well as in 5 healthy children. Different expression of miRNAs in exosomes across all the three groups were screened using miRNA microarray method. Further validated test was conducted through quant...

Fighting an uphill battle": experience with the HCV triple therapy: a qualitative thematic analysis
submitted by ohjarth 23 minutes ago - Topic: Health
Hepatitis C virus (HCV) infections are a severe burden on public health worldwide, causing mortality rates triple that of the general population. Since 2011, for both therapy-naive and therapy-experienced genotype 1 patients, the first generation of direct acting antivirals (DAAs), i.e., the protease-inhibitors (PI) telaprevir and boceprevir have been added to existing dual therapies. The thera...

Simulation-guided design of serological surveys of the cumulative incidence of influenza infection
submitted by ohjarth 23 minutes ago - Topic: Health
Influenza infection does not always cause clinical illnesses, so serological surveillance has been usedto determine the true burden of influenza outbreaks. This study investigates the accuracy of measuringcumulative incidence of influenza infection using different serological survey designs. We used a simple transmission model to simulate a typical influenza epidemic and obtained the seropreval...

Nasal high-frequency oscillation ventilation in neonates: a survey in five European countries
submitted by chorlisd88 24 minutes ago - Topic: Health
Nasal high-frequency oscillation ventilation (nHFOV) is a non-invasive ventilation mode that applies an oscillatory pressure waveform to the airways using a nasal interface. nHFOV has been shown to facilitate carbon dioxide expiration, but little is known about its use in neonates. In a questionnaire-based survey, we assessed nHFOV use in neonatal intensive care units (NICUs) in Austria, Switze...
