Anti-bacterial additive widespread in U.S. waterways
Many rivers and streams in the United Statesare believed to contain a toxic antimicrobial chemical whoseenvironmental fate was never thoroughly scrutinized despite large scaleproduction and usage for almost half a century, according to ananalysis conducted by researchers at the Johns Hopkins Bloomberg Schoolof Public Health. The chemical, triclocarban, has been widely used fordecades in han...Scientists identify genetic pathways essential to RNA interference
A research team based at Massachusetts General Hospital (MGH) has identified 80 new genes essential to the process of RNA interference (RNAi), a powerful new research tool for inactivating genes in plants or animals. They used the RNAi process itself to find new genes that participate in the gene-silencing mechanism, which someday may help to fight human disease. The report will appear in the jou...Opposing fat metabolism pathways triggered by a single gene
Regulating metabolism of fat is an important challenge for any animal, from nematodes to humans. Central players in the regulatory network are the nuclear hormone receptors (NHRs), which are transcription factors that turn on or off a set of target genes when bound by specific lipid molecules. In the premier open-access journal PLoS Biology, Keith Yamamoto and colleagues show that the nuclear hor...Scientists identify genetic pathways essential to RNA interference

The body attempts to protect itself from HIV infection via the innate immune system. Defensins are proteins found in cells, which have been shown to have anti-HIV activity. However, the mechanism by which the defensins control HIV infection has not been known. Appearing online on February 17 in advance of publication in the March 1 print edition of the Journal of Clinical Investigation, Theresa C...Assess the In Vivo Activation of Signal Transduction Pathways with PathDetect Reporting Systems

It has now been found that consumption of hot or cold beverages before recording the body temperature can lead to can lead to drastic fluctuations in temperature measurement. // Consuming a cold beverage or hot beverage was found to hamper the restoration of body temperature to baseline levels by 15 and 23 minutes respectively. Nurses at the University of Virginia Health System have...Gas Masks Don't Always Fit an Emergency
Before the national anxiety over bioterrorism drives you to buy a gas mask at the nearest army surplus store, take a deep breath and brace yourself for what experts say about them -- most of it is not good. One could never know where the exposure is; you'd have to wear the mask at all times. //Even if you could stand to do that, the risks to your health would probably be higher than the l...Traditional Guedel Individually Bagged Oropharyngeal Airways
