Aggressive treatment of brain blood clots can produce a good outcome for many stroke patients

In the study, published in a recent issue of the journal Neurosurgery, 50 percent of stroke patients had little or no neurological disability one to three months after clot-dissolving medication was delivered directly to the site of the blockages, compared to 39 percent of patients with similarly good outcomes documented in a large national trial of intravenous (IV) drug treatment for stroke.

Computer cluster helps understand how human cells and organs work

This will ultimately lead to more effective ways of treating cardiovascular disease and cancer as well as other diseases. It will also eventually allow doctors to tailor treatment in a way specific to that patient rather than a ‘one-size-fits-all’ approach.

Potential new strategy for blocking tumor growth

Targeting a master molecule that helps cancer cells survive when blood oxygen levels are low may offer a potentially powerful strategy for blocking tumor growth, say researchers at The University of Texas M. D. Anderson Cancer Center.

New material, cellular perfluoroelastomers could revolutionise surgery and save lives

The proprietary material was originally developed by the Manchester based company to make artificial blood vessels, used to replace diseased arteries which can lead to heart attacks and strokes, and is capable of making significant improvements in surgery for vascular disease.

65 percent of America’s adults are overweight and 31 percent of adults are obese and at risk for chronic diseases

Government and private sector health experts now estimate that 65 percent of America’s adults are overweight and 31 percent of adults are obese and at risk for chronic diseases such as diabetes and hypertension. The link between obesity and hypertension is well known, but the exact nature of the association between the two disorders remains unclear.

African Americans suffer from cardiovascular diseases at a rate about five times higher than the rest of the U.S. population

African Americans suffer from cardiovascular diseases at a rate about five times higher than the rest of the U.S. population. In a new study, scientists may have found a culprit: a serious deficiency of nitric oxide, a small molecule vital in the regulation of blood flow and blood pressure.

Avastin study shows significant improvement in patients with metastatic colorectal cancer

Genentech, Inc. and Roche have announced that the New England Journal of Medicine published the first Phase III study of an anti-angiogenesis cancer therapy, showing that the addition of Avastin™ (bevacizumab) to the IFL chemotherapy regimen (5-FU/Leucovorin/ CPT-11) significantly extended survival in patients with first-line (previously untreated) metastatic colorectal cancer.

Innovative type of brain scan can determine where blockages of blood to the brain lie

It's a no-brainer that the brain needs a constant supply of blood to keep it going. But some medical conditions can block or reduce that life-giving flow. Whether it's a stroke, a clogged artery or a brain tumor, any situation where blood can't get to the whole brain can lead to death or permanent disability.

Stent methodologies for treating occluded arteries

Branch points in the arteries are a common area of atherosclerotic disease, resulting in the occlusion of both branches. These branch points can generally be defined as a main branch and a side branch, and, in treating the disease, the question of what is the optimal course of action, opening the main branch, the side branch, or both, remains uncertain.

Chocolate is good for your heart

UCSF scientists are publishing sweet results of a study examining chocolate's effects on blood vessel function in healthy people. The team reports that small daily doses of flavonoid-rich dark chocolate consumed over a two-week period improved blood vessels' ability to dilate, or expand.

Daily reduction in the flexibility of blood vessels maybe why heart attacks occur in the early morning

Mayo Clinic researchers have discovered a daily reduction in the flexibility of blood vessels, which may help explain why heart attacks and strokes occur most frequently in the early morning hours. The findings are published June 1 in Circulation: Journal of the American Heart Association.

American Heart reports on acute ischemic stroke and increased risk of bleeding in the brain

High blood levels of a cell-regulating protein in patients with acute ischemic stroke can identify those with an increased risk of bleeding in the brain, according to a report in today’s rapid access issue of Stroke: Journal of the American Heart Association.
