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)...

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...

Meet Ro-bat, Brown University's Robotic Bat Wing

submitted by: nsf
The strong, flapping flight of bats offers great possibilities for the design of small aircraft, among many other applications. By building a robotic bat wing, Brown University researchers have uncovered flight secrets of real bats. Bat wing project leader and NSF Graduate Research Fellow Joseph Bahlman says the faux flapper generates data that could never be collected directly from live animals, and may lead to improved aircraft efficiency and help in the design of small flapping aircraft.
