Evaluation of urinary biomarkers for early detection of acute kidney injury in a rat nephropathy model.

Introduction: The implementation of novel, reliable biomarkers for the early and differential diagnosis of acute kidney injury (AKI) could greatly improve the timely treatment and prevention of disease progression, particularly since the current gold standards for detecting kidney injury such as serum creatinine (SCr) and blood urea nitrogen (BUN) lack sensitivity and specificity. We evaluated novel urinary kidney injury biomarkers focusing on early detection and better prediction of AKI with higher sensitivity and specificity.

Methods: In the rat, urinary biomarkers for kidney injury, i.

Tracking neonicotinoids following their use as cotton seed treatments.

Neonicotinoids are a leading class of insecticides on the global market, accounting for nearly 25%. They are widely used in both agricultural and residential settings. Causing neuron failure by irreversibly binding to the insect nicotinic acetylcholine receptor, neonicotinoids offer broad spectrum efficacy against a variety of pests.

Determination of uptake, accumulation, and stress effects in corn (Zea mays L.) grown in single-wall carbon nanotube contaminated soil.

Single-wall carbon nanotubes (SWNTs) are projected to increase in usage across many industries. Two studies were conducted using Zea L. (corn) seeds exposed to SWNT spiked soil for 40 d.

Total Mercury in Six Antarctic Notothenioid Fishes.

We analyzed white muscle samples from six species of Antarctic fish (suborder Notothenioidei) collected in 2011 from McMurdo Sound, Ross Sea, Antarctica, to assess levels of total mercury (THg). Gymnodraco acuticeps and Trematomus bernacchii exhibited the highest concentrations of THg followed by Trematomus pennellii, Trematomus nicolai, Trematomus newnesi and Pagothenia borchgrevinki, (71.3, 53.
