The Repertoire Of RNAs In Nerve Cell Processes
Neurons transcribe mRNAs in their cell bodies; a small fraction of these mRNAs then travel into dendrites where they are translated. This local translation provides a means for neurons to quickly alter the protein composition of synapses in response to a specific stimulus. To identify mRNAs localized to the dendrites of hippocampal neurons, Poon et al. [click link for full article] (Sat, 30 Dec 2006 00:01:40 GMT)
Ability Of Biomarkers To Predict Risk Of Heart Disease, Stroke Appears Limited
A study of the use of biomarkers to predict the risk of cardiovascular disease and death in an apparently healthy population has found that, even though some measurements are associated with future cardiovascular events, their usefulness for predicting risk in individuals may be limited. The report from the Framingham Heart Study appears in the New England Journal of Medicine. [click link for ... (Sat, 30 Dec 2006 03:01:40 GMT)
Study Identifies Glucose 'sensor' That Plays Dual Role In Glucose Metabolism And Fat Synthesis
In the study, glucose is shown to stimulate the activity of the Liver X Receptors (LXR) a and b, The LXRs act as sensors of dietary components, orchestrating the body's response to nutrients such as oxysterols (short-lived derivatives of cholesterol) and controlling gene expression linked to cholesterol and fat metabolism.

Exercise Response Varies With Genetics - Study Identifies Genes And Mutations Associated With Exercise Traits
Your parents may be to thank - or to blame - for how your body responds to exercise, and the genes responsible are slowly being identified. That’s one of the conclusions of research published by the American College of Sports Medicine (ACSM. [click link for full article] (Sat, 30 Dec 2006 17:01:40 GMT)
Genomic Variation Easier To Identify With 'Microinversions' Software
Computer scientists at the University of California, San Diego, and Brown University have created a software system that more accurately detects "microinversions," mutations that consist of tiny sequences of reversed DNA. The software gives biologists a powerful new tool to study genomic variation between and within species. The system is explained in the online edition of the Proceedings of the ...

Inflammatory Genes Linked To Salt-sensitive Hypertension
One key to your high blood pressure might just be your inflammatory genes. It may sound odd but mounting evidence suggests that inflammation, a part of the immune response implicated in diseases such as cancer, Alzheimer's and diabetes, may also help translate stress into high blood pressure.

Study Sheds New Light On Rare Immunodeficiency Disease
USC researchers have determined the 3-D atomic structure of the Apo2 protein, the first of the APOBEC enzyme family to be described. The protein structure has guided them to a new understanding of what goes wrong on a molecular level in a rare, but serious immunodeficiency syndrome. (Sun, 31 Dec 2006 16:02:40 GMT)
Release of sheep genome map a significant milestone for industry
Breeding the right sheep, whether it's for improved wool, more muscle, increased fertility or a better ability to cope with parasites, has been one of the sheep industry's greatest challenges. (Sun, 31 Dec 2006 18:19:54 GMT)
India youth power in the globalised world
India has to work hard in value addition techniques in its manufacturing industries, in honing core competency of skilled manpower, in procuring raw materials, and in upgrading capital equipment so that it becomes competitive in a globalised world. (Sun, 31 Dec 2006 21:12:14 GMT)
