Issues On Cholesterol: Diet, Statins And Genetics

Genetic lipoprotein disorders are frequently seen in patients with premature coronary artery disease (CAD). An example of strong genetic predisposition is the disorder: familial hypercholesterolemia, where a single gene defect (the low density lipoprotein receptor) contributes to most of the familial expression of CAD.

Decipering Of Telomerase Structure Opens Door To New Cancer, Aging Treatments

Researchers at The Wistar Institute have deciphered the structure of the active region of telomerase, an enzyme that plays a major role in the development of nearly all human cancers. The landmark achievement opens the door to the creation of new, broadly effective cancer drugs, as well as anti-aging therapies. Researchers have attempted for more than a decade to find drugs that shut down telomerase - widely considered the No.

Water: Stressed-Out And Overheated

Water is the basis of all life on earth, yet freshwater animals and plants are being lost faster than in any other ecosystem. The dominant causes are the many stressors that affect lakes, rivers and wetlands globally: habitat loss, over-fishing, invasions by alien species, dams, over-abstraction, many forms of pollution and increasing salinity. Fresh waters are also highly sensitive to climate change which now exacerbates all these other problems.

Bone That Blends Into Tendons Created By Engineers Create
01.09.2008 04:24

Engineers at Georgia Tech have used skin cells to create artificial bones that mimic the ability of natural bone to blend into other tissues such as tendons or ligaments. The artificial bones display a gradual change from bone to softer tissue rather than the sudden shift of previously developed artificial tissue, providing better integration with the body and allowing them to handle weight more successfully. The research appears in the Proceedings of the National Academy of Sciences.

"Instructor" Molecule Discovered That Makes Blood Vessel Cells Form Tube-Like Structures
01.09.2008 04:24

How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific journal Blood, might be an important step towards using stem cells to build new organs.

9-Year Study Confirms That vCJD Can Be Transmitted Through Blood Transfusion In Humans

The findings underline the importance of precautions against vCJD transmission, such as the Government decision in 2004 to ban blood donations from anyone who had received a blood transfusion since 1980. The study published in Blood, the journal of the American Society of Hematology, looked at BSE transmission between sheep through infected blood with the aim of quantifying how vCJD - the human form of BSE - could be spread through transfusions.

Location, Location, Location Important For Genes, Too

Cells become cancerous mainly because they lose control of their growth. To better understand how this happens, a new study at Ohio State University's Comprehensive Cancer Center looks at four genes that help regulate cell growth in embryos and that contribute to cancer in adults. The genes - E2f1, E2f2, and E2f3a and E2f3b - are generally believed to work together to help control cell proliferation, a belief that comes from experiments using only cells.

Stanford Research Shows New Approach, Old Drug Show Promise Against Hepatitis C
01.09.2008 04:24
medicalnewstoday.com
The fight against the liver disease hepatitis C has been at something of an impasse for years, with more than 150 million people currently infected, and traditional antiviral treatments causing nasty side effects and often falling short of a cure. Using a novel technique, medical and engineering researchers at Stanford University have discovered a vulnerable step in the virus' reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine.

DNA Tubes With Programmable Sizes For Nanoscale Manufacturing Created By Caltech Scientists
01.09.2008 04:23
medicalnewstoday.com
Scientists at the California Institute of Technology (Caltech) have developed a simple process for mass producing molecular tubes of identical--and precisely programmable--circumferences. The technological feat may allow the use of the molecular tubes in a number of nanotechnology applications. The molecular tubes are composed of wound-up strands of DNA.
