Association between water consumption and body weight outcomes: a systematic review

submitted by: Rebecca
BACKGROUND Drinking water is often applied as a dietary means for weight loss and overweight/obesity prevention, but no evidence-based recommendation exists for this indication. OBJECTIVE We summarized the existing evidence on the association between water consumption and body weight outcomes in adults of any body weight status. DESIGN In a systematic review, we retrieved studies from 4 electronic databases (MEDLINE, EMBASE, CINAHL, and COCHRANE), cross-references by PubMed functions...

biosights: July 8, 2013 - Vinculin delivers a clutch performance

submitted by: JCB
At the leading edge of migrating cells, actin assembly and membrane protrusion are closely coupled with the formation of integrin-based focal adhesions that attach to the extracellular matrix. Thievessen et al. reveal that the focal adhesion protein vinculin acts as part of a molecular clutch that engages actin flow to coordinate actin and focal adhesion dynamics. This biosights episode presents the paper by Thievessen et al. from the July 8, 2013, issue of The Journal of Cell Biology and...

Diet, microbiota, and microbial metabolites in colon cancer risk in rural Africans and African Americans

submitted by: sjokeefe
Background: Epidemiologic studies have suggested that most cases of sporadic colon cancer can be attributed to diet. The recognition that colonic microbiota have a major influence on colonic health suggests that they might mediate colonic carcinogenesis. Objective: To examine the hypothesis that the influence of diet on colon cancer risk is mediated by the microbiota through their metabolites, we measured differences in colonic microbes and their metabolites in African Americans with a...

biosights: June 10, 2013 - Netrin Throws Anchor Cells into the Breach

submitted by: JCB
Cell invasion through basement membranes is crucial for both normal development and cancer metastasis but relatively little is known about the process because it is difficult to observe in vivo. By imaging the invasion of anchor cells during C. elegans development, Hagedorn et al. reveal that, after invadopodia-like structures form an initial breach in the basement membrane, localized netrin signaling helps generate a stable invasive protrusion that widens the gap and directs the cell across...

Echogram of the Red Sea

submitted by: apryl
This is a short clip intended for use at the KAUST SIGGRAPH booth in a series of video loops played during the convention. 62,000+ pixels wide, this image can be viewed in full resolution on the 40 Gigapixel tiled display wall at KAUST Visualization Laboratory. It is also annotated with sound clips that describe specific areas of the dataset as you bring them into view. Data provided by: Dr. Stein Kaartvedt, KAUST Professor, Marine Science Associate Director, Red Sea Research Center...
