Living sensor can warn of arsenic pollution

Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Rattlesnake-type poisons used by superbug bacteria to beat our defences

Colonies of hospital superbugs can make poisons similar to those found in rattlesnake venom to attack our bodies' natural defences, scientists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.

Health care professionals seeing more children with fatty liver disease; condition prevalent among Hispanics

As many as 2% to 5% of children older than age five -- most of whom are obese -- are thought to have nonalcoholic fatty liver disease, and the condition seems to be most prevalent among Hispanic children, the AP/San Mateo Daily Journal reports.

Oxidative stress: mechanism of cell death clarified

Dr. Marcus Conrad of the Institute of Clinical Molecular Biology and Tumor Genetics at the Helmholtz Zentrum Munchen has decrypted the molecular mechanism through which the death of cells is caused by oxidative stress.

New hope for treating common form of inherited neuromuscular disease

Treatments that ramp up production of the tiny "motors" that power cells may have promise for treating one of the most common forms of inherited neuromuscular disease, according to a report in the September Cell Metabolism, a Cell Press publication. Neuromuscular disorders caused by defects in those mitochondrial motors affect a large number of children and adults worldwide, but today remain without treatment, the researchers said.

Researchers find genetic proof on how osteoarthritis destroys cartilage

A team of orthopaedic researchers has found definitive, genetic proof of how the most common form of arthritis destroys joint cartilage in nearly 21 million aging Americans, according to a study published online Sept. 2 in the Journal of Bone and Mineral Research. The findings serve as an important foundation for the design of new treatments for osteoarthritis (OA), researchers said.

New discovery on growth factor - breakthrough for cancer research

A research team at the Ludwig Institute and Uppsala University has discovered an entirely new signal path for a growth factor that is of crucial importance for the survival and growth of cancer cells.

Factor Xa inhibitor Apixaban and antiplatelet therapy after acute coronary syndrome

Data from a phase II study of an investigational drug designed to block formation of blood clots show potential for added protection against a second heart attack or stroke among patients who are already taking state-of-the-art prevention therapy.

Discovery of tumour growth enzyme could lead to new cancer drugs

Scientists say a landmark study has revealed an enzyme which is vital to the growth of many cancers.

Anti-itching drug clemizole shows promise against hepatitis C

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.

The BEAUTIFUL study: Ivabradine and the reduction of cardiovascular events

The results of the much awaited BEAUTIFUL (morBidity-mortality EvAlUaTion of the If inhibitor ivabradine in patients with CAD and left ventricULar dysfunction) trial have shown that coronary artery disease (CAD) patients with left ventricular dysfunction (LVD) and a heart rate more than 70 bpm have a significantly higher risk of cardiovascular death and other cardiovascular events and in these patients (heart rate above 70 bpm) treatment with ivabradine further reduces the risk of the most important coronary events such as fatal and non-fatal myocardial infarction and coronary revascularisation by one third, even when these patients are already receiving optimal therapy.

Global study shows Telmisartan reduces outcome of cardiovascular death, heart attack or stroke

An international study led by Canadian researchers has found that telmisartan, a medication used to lower blood pressure, reduced the outcome of cardiovascular death, heart attack or stroke in people who are unable to tolerate a widely available and effective standard treatment.

Researchers devise means to create blood by discovering earliest form of human blood stem cells

Johns Hopkins researchers have discovered the earliest form of human blood stem cells and deciphered the mechanism by which these embryonic stem cells replicate and grow. They also found a surprising biological marker that pinpoints these stem cells, which serve as the progenitors for red blood cells and lymphocytes.

Study reveals how blood flow force protects against atherosclerosis

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology. By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the cause of clogged arteries that lead to heart attack and stroke, the authors said. The next set of studies, already underway, seeks to "tweak" the process with the goal of designing a new class of therapies.

Researchers discover key details of how rheumatoid arthritis destroys bone

Researchers have discovered key details of how rheumatoid arthritis (RA) destroys bone, according to a study published in the Aug. 22 edition of the Journal of Biological Chemistry. The findings are already guiding attempts to design new drugs to reverse RA-related bone loss and may also address more common forms of osteoporosis with a few adjustments.

ICMT enzyme shows potential as target in treating blood cancer

A discovery by a research team with the Sahlgrenska Academy at Gothenburg University in Sweden may lead to new treatments for blood cancer and other diseases. By stopping the production of a specific enzyme, ICMT, researchers were able to alleviate disease symptoms in mice with blood cancer.
