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.

Short-term exercise significantly increases insulin action

Carefully controlling the amount of food and drink that formerly sedentary, overweight people ingest during and after short-term exercise has a significant impact on insulin action.

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.

Prognostic factors influencing survival in patients with brain metastases identified

Allos Therapeutics has announced the presentation of new findings from its Phase 3 clinical trial of the investigational radiation sensitizer Efaproxyn (efaproxiral) in patients with brain metastases.

A revolutionary approach to angiogenesis could make cancer treatment more effective at killing tumours

Dr. Olivier Feron and his team from the University of Louvain Medical School in Brussels have turned the whole concept of targeting tumour blood vessels on its head. Instead of the conventional approach of trying to starve tumour cells of the blood supply they need to grow, they are doing the opposite – opening up the tumour blood supply to allow better access for cancer drugs and more effective radiotherapy.

Clusters of genes within human aortas appear to predict risk for atherosclerosis

Duke University Medical Center researchers have identified specific clusters of genes within human aortas that appear to predict with great specificity which patients may be at highest risk for developing atherosclerosis, as well as the severity of the disease.

Guidant announces plans to initiate vulnerable plaque study

Guidant has announced plans to conduct a study designed to increase clinical understanding of “vulnerable” plaques – lipid-rich coronary lesions that suddenly rupture – that may cause most heart attacks.

Findings have implications for understanding psychiatric and neurological disease that affect the hippocampus

Spatial memory is more vulnerable than object recognition memory when damage occurs in the brain’s memory processing center, the hippocampus, according to memory specialists at the University of California, San Diego (UCSD) School of Medicine

Pneumonia could be treatable by the oral antibiotic amoxicillin rather than injectable penicillin

Pneumonia - one of the world’s deadliest diseases for young children in developing countries - could be treatable by the oral antibiotic amoxicillin rather than injectable penicillin, with implications for better health outcomes and reduced costs

Stress response proteins offer a promising target for a novel drug guidance system

Their study, published in the September issue of the journal Cancer Cell, demonstrates how researchers can find protein tags that are unique to cancer cells and then tweak a drug delivery system to zero in on those tags and destroy the cells.

World's most powerful magnetic resonance imaging machine for human studies

The University of Illinois at Chicago unveiled today the world's most powerful magnetic resonance imaging machine for human studies, capable of imaging not just the anatomy but metabolism within the brain.

Vanilla may become a drug to treat sickle cell disease

In addition to its popular role in flavoring ice cream, fudge and cake frosting, vanilla may have a future use as a medicine. Recent laboratory research has strengthened the possibility that a form of vanilla may become a drug to treat sickle cell disease.

New culprit behind the brain injury suffered by stroke victims

Researchers have uncovered a new culprit behind the brain injury suffered by stroke victims. Their new study, published in the Sept. 17 issue of Cell, links brain cell damage to a rise in brain acidity following the oxygen depletion, or ischemia, characteristic of stroke.
