Alzheimer's marker amyloid beta 42 linked to brain damage

Researchers at Washington University School of Medicine in St. Louis have linked a potential indicator of Alzheimer's disease to brain damage in humans with no signs of mental impairment.

Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.

University at Buffalo to receive $4.9 million in stem cell research funds from New York State

The University at Buffalo will receive $4.9 million in funding to conduct research on stem cells, part of a new investment in stem cell research announced yesterday by New York State Governor David A. Paterson.

Tiny samples could yield big predictive markers for pancreatic cancer

A handful of proteins, detected in incredibly tiny amounts, may one day help doctors distinguish between a harmless lesion in the pancreas and a potentially deadly one, say researchers at Fox Chase Cancer Center.

Teenage stress carries forward to adulthood

Most of us remember our teenage years with a mix of fondness and relief. Fondness for the good memories, and relief that all that teenage stress, angst and drama - first love, gossip, SATs, fights with parents - is behind us.

Researchers create gene circuit that permits precise tuning of a gene's expression in a cell

Researchers have crafted a gene circuit that permits precise tuning of a gene's expression in a cell, an advance that should allow for more accurate analysis of the gene's role in normal and abnormal cellular function.

Salt could be 'nature's antidepressant' according to new research

Most people consume far too much salt, and a University of Iowa researcher has discovered one potential reason we crave it: it might put us in a better mood.

Small molecules block cancer gene

Finding molecules that block the activity of the oncogene Stat 3 (signal transducer and activator of transcription) required screening literally millions of compounds, using computers that compared the structure of the cancer-causing gene to those of the small molecules, said a Baylor College of Medicine researcher in a report that appears in the current online issue of the journal PLoS One (Public Library of Science ONE).

Simple test helps predict heart attack risk

The use of common and readily available screening tests - like the ankle brachial index (ABI) - along with traditional risk scoring systems - such as the Framingham Risk Score - has the potential to prevent devastating heart attacks in thousands of individuals who are not originally thought to be at high risk (according to Framingham alone), say researchers at the Society of Interventional Radiology's 34th Annual Scientific Meeting.

'Seeing' stem cells helps in fight against peripheral arterial disease

Interventional radiologists are fitting together the puzzle pieces of how to use stem cells to create new or more blood vessels to treat peripheral arterial disease (PAD) in those individuals with extensively narrowed or clogged arteries.

Scientists discover key molecules that inhibit viral production

The research, led by Professor Donny Strosberg of Scripps Florida, was published on March 4, 2009, in the Journal of General Virology's advance, online edition, Papers in Press.

SOX9 protein may be a potential target for melanoma treatment

In a new study released today, researchers have shown that a specific protein plays an important role in inhibiting the development and spread of melanoma tumors in mouse and in human skin models.

Discovery of new mechanism the malaria parasite uses to enter human red blood cells

Virginia Commonwealth University Life Sciences researchers have discovered a new mechanism the malaria parasite uses to enter human red blood cells, which could lead to the development of a vaccine cocktail to fight the mosquito-borne disease.

Saving limbs with drug-eluting stents

Attempts to treat critical limb ischemia in peripheral arterial disease (PAD) patients with below-the-knee angioplasty are still thwarted by restenosis (the re-narrowing of the artery at the site of angioplasty or stenting), the need for repeat treatments and the continued progression of atherosclerotic disease, leading to tissue death (gangrene) and amputation.

Extra workplace decibels increase risks of work-related accidents and road collisions

The majority of the 650,000 employees from Quebec's manufacturing sector - specifically those working in metallurgy and sawmilling - are exposed to noise levels that exceed governmental norms.

Interventional treatment can be recommended as first-line treatment for 'silent killer'

Endovascular or endograft repair, a minimally invasive interventional radiology treatment that uses stent grafts to treat abdominal aortic aneurysms (AAA), has low re-intervention rates that are comparable to those reported for open surgical repair-and can be recommended as first-line treatment, according to a study released at the Society of Interventional Radiology's 34th Annual Scientific Meeting.
