Survival estimates across five life stages of redfin () exposed to simulated pumped-storage hydropower stressors.

The global prevalence of pumped-storage hydropower (PSH) is expected to grow exponentially as countries transition to renewable energy sources. Compared to conventional hydropower, little is currently known regarding PSH impacts on aquatic biota. This study estimated the survival of five life stages (egg, two larval stages, juvenile and adult) of redfin (European) perch () following passage through a PSH facility during the pumping phase.

Millennial scale persistence of organic carbon bound to iron in Arctic marine sediments.

Burial of organic material in marine sediments represents a dominant natural mechanism of long-term carbon sequestration globally, but critical aspects of this carbon sink remain unresolved. Investigation of surface sediments led to the proposition that on average 10-20% of sedimentary organic carbon is stabilised and physically protected against microbial degradation through binding to reactive metal (e.g.

Mortality events resulting from Australia's catastrophic fires threaten aquatic biota.

The consequences of the 2019-2020 bushfires in Australia were also devastating for the aquatic biota. Following abnormal rainfall events in burnt areas, widespread mortality events including fish and invertebrates were recorded in estuarine and freshwater systems. Such negative impacts on aquatic resources highlight the need to include these ecosystems in bushfire recovery plans.

High prevalence of disability and HIV risk among low socioeconomic status urban adults, 17 U.S. cities.

Background: In the United States, approximately 10% of adults 18-64 years are disabled. However, there is scarce literature on the associations between disability and HIV risk.

Objective: To assess disability prevalence and its associations to health and HIV risk factors among low socioeconomic status (SES) (≤high school education or ≤ poverty guidelines) urban adults.

Subacute Gummy Vitamin Overdose as a Rare Manifestation of Child Neglect.

We present a case of a 20-month-old girl who presented to the emergency department with anorexia, progressive weakness, and lethargy who was found to have severe hypercalcemia (20.7 mg/dL) and vitamin D hypervitaminosis. Further questioning revealed that this was secondary to a subacute toxic ingestion of "L'il Critters" calcium and vitamin D3 gummy vitamins that were being administered by the patient's mother multiple times a day for several weeks or even months.

Predictors and Prevalence of Pain and Its Management in Four Regional Cancer Hospitals in India.

Purpose: More than 1 million new occurrences of cancer are diagnosed in India annually. Among patients with cancer, pain is a common and persistent symptom of the disease and its treatment. However, few studies to date have evaluated the prevalence of pain and the adequacy of pain management in Indian hospitals.

Duration of the Presence of Infectious Zika Virus in Semen and Serum.

Zika virus (ZIKV) has recently caused a large epidemic in the Americas that is associated with birth defects. Although ZIKV is primarily transmitted by Aedes mosquitoes, ZIKV RNA is detectable in blood and semen of infected individuals for weeks or months, during which sexual and other modes of transmission are possible. However, viral RNA is usually detectable longer than infectious virus is present.

Multiple factors predict physical performance in people with chronic liver disease.

Objective: The aim of this study was to assess whether physical performance correlates with metabolic and inflammatory measures in research subjects with chronic liver disease.

Design: This is a prospective, descriptive cohort study correlating performance on a 6-min walk test with cardiorespiratory variables, metabolic measures (glucose [GLU], C-peptide insulin, and lipids), liver enzymes (aspartate aminotransferase and alanine aminotransferase), and the proinflammatory cytokine interleukin-8 (IL-8).

Results: This study enrolled 51 subjects (18 women) with chronic liver disease: 41% (n = 21) with nonalcoholic fatty liver disease and 59% (n = 30) with hepatitis C virus.

Isolation of a highly thermal stable lama single domain antibody specific for Staphylococcus aureus enterotoxin B.

Background: Camelids and sharks possess a unique subclass of antibodies comprised of only heavy chains. The antigen binding fragments of these unique antibodies can be cloned and expressed as single domain antibodies (sdAbs). The ability of these small antigen-binding molecules to refold after heating to achieve their original structure, as well as their diminutive size, makes them attractive candidates for diagnostic assays.
