Grape Powder Supplementation Prevents Oxidative Stress–Induced Anxiety-Like Behavior, Memory Impairment, and High Blood Pressure in Rats

submitted by: ssalim
We examined whether or not grape powder treatment ameliorates oxidative stress–induced anxiety-like behavior, memory impairment, and hypertension in rats. Oxidative stress in Sprague-Dawley rats was produced by using L-buthionine- (S,R)-sulfoximine (BSO). Four groups of rats were used: 1) control (C; injected with vehicle and provided with tap water), 2) grape powder–treated (GP; injected with vehicle and provided for 3 wk with 15 g/L grape powder dissolved in tap water), 3)...

Factors predicting overweight in US kindergarteners

submitted by: glflor
BACKGROUND: Childhood overweight is a substantial public-health problem, but little is known about predictors of early childhood overweight. OBJECTIVE: We aimed to identify factors-alone and in combination-that predict kindergarten overweight. DESIGN: We analyzed nationally representative data from the Early Childhood Longitudinal Study-Birth Cohort, a longitudinal cohort study of 6800 children followed from birth through kindergarten. Multivariable logistic regression and recursive...

biosights: May 13, 2013 - Ventral lamellipodia plug the gaps

submitted by: JCB
When leukocytes enter or exit the blood stream, they leave small wounds both in and between the vascular endothelial cells, which must be quickly repaired so that the endothelium can maintain its barrier function. Martinelli et al. reveal that wounding causes a loss of tension in endothelial cells, inducing the formation of ventral lamellipodia that close the holes left by transmigrating leukocytes. This biosights episode presents the paper by Martinelli et al. from the April 29, 2013, issue...

Bacterial Aerotaxis

submitted by: mhrussel

Aerotaxis is the movement of an organism in response to environmental oxygen concentrations, either towards or away from a given oxygen concentration. Many bacteria are microaerophilic meaning they prefer environments with low oxygen content. Higher or lower O2 content than the optimum are considered a repellant and bacteria will navigate towards the optimum. This animation is an overview of studying aerotaxis in motile bacteria.

Glycolysis animation

submitted by: mhrussel

Glycolysis is a determined sequence of ten reactions involving ten intermediate compounds (one of the steps involves two intermediates). The intermediates provide entry points to glycolysis. This animation features the 3D protein structures of all ten enzymes as well as the enzyme substrate and products.
