Blood Vessel News and Research

Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

New technique to view labeled tumor cells in 'real' time

A breakthrough technique that allows scientists to view individually-labeled tumor cells as they move about in real time in a live mouse may enable scientists to develop microenvironment-specific drugs against cancer, researchers report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Researchers create tiny, implantable device that captures and kills cancer cells in the bloodstream

In a new tactic in the fight against cancer, Cornell University researcher Michael King has developed what he calls a lethal "lint brush" for the blood -- a tiny, implantable device that captures and kills cancer cells in the bloodstream before they spread through the body.

High phosphorus levels in blood linked to coronary calcification in chronic kidney disease

For patients with moderate chronic kidney disease (CKD), higher levels of phosphorus in the blood are associated with increased calcification of the major arteries and heart valves - which may contribute to the increased risk of cardiovascular disease in patients with CKD, reports a study in the Journal of the American Society of Nephrology (JASN).

New approaches to prevent blood clots

The largest study ever to examine the preventive use of blood-thinning medication to help prevent deadly blood clots in patients with cancer undergoing chemotherapy presented December 7 during the 50th Annual Meeting of the American Society of Hematology in San Francisco, CA.

Biomarkers in blood could aid diagnosis of two severe and debilitating forms of malaria

Canadian researchers have identified protein biomarkers that shed new light on the development of two severe and debilitating forms of malaria.

Scientists show that endothelial cells give rise to blood stem cells

Stem cell researchers at UCLA have proven definitively that blood stem cells are made during mid-gestational embryonic development by endothelial cells, the cells that line the inside of blood vessels.

ACE inhibitor calcium channel blocker combo drug shown to reduces heart attacks

While doctors are urged to start with a diuretic-based strategy to control patients' high blood pressure, an international blood pressure study shows a different single-pill drug combination is more effective at preventing heart-related events such as heart attacks and strokes.

Portable eight-slice CT in ER increases chance of stroke survival and recovery

New research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment.

More evidence on why the Mediterranean diet is good for heart

Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research.

Exercise helps blood flow in senior brains

Older adults who exercise regularly show increased cerebral blood flow and a greater number of small blood vessels in the brain, according to findings presented today at the annual meeting of the Radiological Society of North America (RSNA).

Multitasking proteins driving cell behavior

A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics - that the proteins driving cell behavior are doing so much multitasking that it would be near impossible to group them according to a few discrete functions.

Novel target for therapeutics against Staphylococcus aureus

Researchers at the Texas A&M Health Science Center Institute of Biosciences and Technology, and the University of Edinburgh have uncovered how a bacterial pathogen interacts with the blood coagulation protein fibrinogen to cause methicillin-resistant Staphylococcus aureus (MRSA) infections, a finding that could aid in developing therapeutics against the potentially deadly disease.

Advanced CT scans 100 percent accurate in checking for clogged arteries

In a development that researchers say is likely to quell concerns about the value of costly computed tomography (CT) scans to diagnose coronary artery blockages, an international team led by researchers at Johns Hopkins reports solid evidence that the newer, more powerful 64-CT scans can easily and correctly identify people with major blood vessel disease and is nearly as accurate as invasive coronary angiography.

Mechanisms of cardiovascular disease and cancer give clues to new therapies

Cardiovascular conditions leading to heart attacks and strokes are treated quite separately from common cancers of the prostate, breast or lung, but now turn out to involve some of the same critical mechanisms at the molecular level.

Angioplasty safer in community hospitals when team has more experience

Heart experts at Johns Hopkins have evidence that life-saving coronary angioplasty at community hospitals is safer when physicians and hospital staff have more experience with the procedure.

Neck arteries of obese children and teens look more like those of 45-year-olds

Researchers used ultrasound to measure the thickness of the inner walls of the neck (carotid) arteries that supply blood to the brain. Increasing carotid artery intima-media thickness (CIMT) indicates the fatty buildup of plaque within arteries feeding the heart muscle and the brain, which can lead to heart attack or stroke.

Nanomatrix stent coating designed to mimic natural endothelium

A nanomatrix for stent coating designed at the University of Alabama at Birmingham (UAB) mimics natural endothelium, the substance that lines blood vessels, and promises the potential to prevent post-operative tissue scaring along the blood vessel wall, greatly reducing the possibility of future thrombosis, or blockage at the stent site.

Joyful music has a healthy effect on blood vessel function

Listening to your favorite music may be good for your cardiovascular system.

Medicine, math and engineering combine to reveal how sepsis and less severe infections occur

It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.

Drug-eluting better than bare metal stents in diabetics

Drug-eluting stents reduced the risk of revascularization, heart attack and death in diabetics as compared with bare-metal stents in the largest observational comparison, researchers reported at the American Heart Association's Scientific Sessions 2008.
