International society agrees that the potential of stem cells derived from fat show promising clinical uses

While questions still remain about the nature and function of stem cells found in fat, a group of researchers and clinicians convened today in Pittsburgh at the Second Annual Meeting of the International Fat Applied Technology Society (IFATS) agreed that research should move forward with the ultimate goal of performing human clinical trials to test the cells' therapeutic potential for specific indications.

Balance between vasodilation and vasoconstriction in exercising muscle may change with age

The “fight or flight” mechanism is one of the best-known physiological responses. It increases our ability to respond to stressful situations. One way to look at exercise – physiologically -- is as a non-life-threatening example of a stressful situation.

High-tech isometrics helps persons on hypertension medication

Don’t try this at home, but a high-tech version of the muscle crowd’s hand-grip has demonstrated the ability to lower blood pressure, improve the flexibility of the carotid artery and heighten vasoactive sensitivity in people taking medication for hypertension.

New genomic, proteomic tools yield clues to exercise/diet effects on obesity, metabolic syndrome and diabetes

Applying the latest genomic and proteomic techniques has given researchers new clues for the interaction between exercise and diet, glucose metabolism and improvement in cardiovascular disease (CVD) risk factors.

Mechanical loading through exercise builds bone strength

Mechanical loading through exercise builds bone strength and this effect is most pronounced during skeletal growth and development, according to Charles H. Turner, professor in the Department of Orthopaedic Surgery and director of orthopaedic research at the Indiana University School of Medicine, Indianapolis.

Research helps to understand the basic mechanism that underlies how neurons communicate

Nerve cells with a mutant calcium channel don't communicate as effectively as those with a normal calcium channel, according Saint Louis University research that is published in the Proceedings of the National Academy of Sciences Online Early Edition the week of Oct. 4.

University of Florida researchers reveal secret lives of genes during spinal injury

The body attempts to heal a damaged spinal cord in much the same way it repairs skin after simple cuts and scrapes, an insight that may lead to new treatments for the thousands of people paralyzed each year because of spinal cord injuries, say scientists at the University of Florida Health Science Center.

Natural alternatives to osteoarthritis drug

The recall of Vioxx should come as a major sign of the need to look for safer alternatives for osteoarthritis treatment, according to the Director of the Australian Centre for complementary Medicine Education and Research (ACCMER), Professor Stephen Myers.

Spitting into a cup could someday be an alternative to blood testing

Researchers have identified the largest number of proteins to date in human saliva, a preliminary finding that could pave the way for more diagnostic tests based on saliva samples. Such tests show promise as a faster, cheaper and potentially safer diagnostic method than blood sampling, they say.

Neurologists have discovered a drug application smart enough to alleviate orthostatic hypotension

Mayo Clinic neurologists have discovered a drug application smart enough to alleviate orthostatic hypotension -- problems with sinking blood pressure when standing up from a sitting position -- without the unwanted effect of also causing patients' blood pressure to soar when lying down.

Boosting the blood count in conjunction with radiation therapy doesn't improve survival for head and neck cancer patients

Boosting the blood count – in effect, curing anemia – in conjunction with radiation therapy won't help patients with head and neck cancer fare any better than with radiation alone, says a national study led by Jefferson Medical College researchers.

A trial of beta-interferon-1a in inclusion-body myositis has failed to find benefit from the drug in this disease

A trial of beta-interferon-1a in inclusion-body myositis (IBM) has failed to find benefit from the drug in this disease. Beta-interferons counteract some of the activities of the immune system, which some experts believe is misguided in IBM.

Scientists have shown that the textbook explanation of how enzymes work is wrong

Their discovery may explain why attempts to make artificial enzymes have often been disappointing. Industry must now re-think the rationale for the design of biological catalysts and its approaches to drug design.
