New Anatomy and Biotechnology Resources Published at

(PRWEB) January 28, 2012 is a Web 2.0 sciences social network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. currently contains over 1.3 million stories distributed among 75 categories. Over 75,100 users monitor nearly 8,200 journals covering the broad spectrum of sciences. They share circa 2,500 new articles every day. Since new science content is discovered in real-time, the delay between original publication and appearance at is no more than two days.’s Biology Sciences Category covers life and living organisms, including their structure, function, growth, origin, evolution, and distribution. Besides Anatomy and Biotechnology, its ten subsections include Genetics, Microbiology, Ecology, Environment, Agriculture, Forestry, Physiology and Zoology. This category currently contains 77,742 stories partly derived from 400 science journals publishing in these two disciplines.’s Anatomy Sciences Category deals with the shape and structure of organisms and their parts. It currently contains over 1,000 articles partly deriving from over 10 scientific anatomy journals. One of the latest additions shows that the relationship between shear rate and flow-mediated dilation (FMD) is altered by acute exercise. The aims of this study were to compare brachial artery endothelial function at rest and post-exercise in and to compare the data expressed as a percent change and normalized to shear rate. These aims are based on the fact that endothelial function is a predictor of cardiovascular health and is improved with exercise training, however, it is not clear how exercise acutely affects endothelial function. Results of this study show a weak relationship in flow-mediated dilation and shear rate after exercise. These data suggest that data recorded following aerobic exercise should not be normalized. Thus, endothelial function was attenuated after a continuous 30-minute aerobic exercise session. Another recently included article shows that sprint exercise enhances skeletal muscle p70S6k phosphorylation and more so in women than in men. Sprint exercise is characterized by repeated sessions of brief intermittent exercise at a high relative workload. However, little is known about the effect on mTOR pathway, an important link in the regulation of muscle protein synthesis. The authors tested the hypothesis that the activation of mTOR signalling is more pronounced in women than in men and conclude that repeated 30 seconds all-out bouts of sprint exercise separated by 20 minutes of rest increases Akt/mTOR signalling in skeletal muscle. They also measured that downstream signaling of mTOR was stronger in women than in men after sprint exercise indicated by the increased phosphorylation of p70S6k.’s Biotechnology Sciences Category covers the utilization of bacteria, yeasts and other biological substances for industrial and manufacturing processes. It currently contains over 5,200 articles partly deriving from over 25 scientific biotechnology journals. One recent article in this category covers biotransformation of ginsenosides Re and Rg1 into ginsenosides Rg2 and Rh1 by recombinant β-glucosidase. Ginsenosides Re and Rg1 were transformed by recombinant β-glucosidase (Bgp1) to ginsenosides Rg2 and Rh1. Using Bgp1 enzyme, almost all initial ginsenosides Re and Rg1 were converted completely to ginsenosides Rg2 and Rh. This is the first report of the conversion of ginsenoside Re to ginsenoside Rg2 and ginsenoside Rg1 to ginsenoside Rh1 using the recombinant β-glucosidase. Another recently included article in this category characterizes d-lactate dehydrogenase from Pediococcus acidilactici that converts phenylpyruvic acid into phenyllactic acid. The authors cloned the gene coding for d-lactate dehydrogenase (d-LDH) from Pediococcus acidilactici DSM 20284 and expressed it in E. coli. The recombinant enzyme was purified by nickel-affinity chromatography. It converted phenylpyruvic acid (PPA) to 3-phenyllactic acid maximally at 30°C and pH 5.5 with a specific activity of 140 and 422 U/mg for PPA and pyruvate.’s content is divided into “Popular” and “Upcoming” sections. While content in the “Upcoming” section is rarely older than a few minutes, the “Popular” section contains approved articles approved between 20 to 60 minutes after submission by users. All articles can easily be bookmarked with the AddThis Sharing tools which include the Google+1 button. The website provides an advanced search feature which suggests up to ten closely related articles for a search and also for a selected story. The latter list is sorted primarily by relevancy and secondarily by publishing date. This helps users compiling lists of related references for literature retrieval purposes.

Other features include a “Life Traffic Feed” which is helpful in watching the online traffic in real-time and a “Top Content” sidebar which includes the most actively read and shared articles available on the site. The included Google Translate gadget supports translating’s content into over fifty languages. offers users to stay updated with the latest inclusions and news in their favorite science topics by subscribing to one or more of the seventy-five RSS feeds which are available for every category. also maintains the new Twitter account @ScienceIndex_ for improving public exposure and inform their users about the latest developments in the sciences.
