The Anatomy and
Biotechnology Sciences are two of the key categories
covered by the
Sciences Social network ScienceIndex.com. The users of
the website monitor nearly 190 scientific journals publishing
in these two disciplines. ScienceIndex.com was 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.

ScienceIndex.com 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. ScienceIndex.com 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
ScienceIndex.com is no more than two days.

ScienceIndex.com'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.

ScienceIndex.com'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.

ScienceIndex.com'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 ?-glucosidase. Ginsenosides Re and Rg1 were
transformed by recombinant ?-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 ?-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.

ScienceIndex.com'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 ScienceIndex.com "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 ScienceIndex.com's
content into over fifty languages.

ScienceIndex.com 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. ScienceIndex.com also
maintains the new Twitter account @ScienceIndex_ for improving
public exposure and inform their users about the latest
developments in the sciences.
