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

Signs of atherosclerosis seen in apparently healthy young adults

Young adults who seem to be healthy, but have a clustering of heart disease risks factors known as metabolic syndrome, tend to have signs of thickening of their carotid artery walls, which is an early indication of atherosclerosis, according to a new study in the Aug 2, 2005, issue of the Journal of the American College of Cardiology.

Arf gene prevents excessive growth of blood vessels in the developing eye

A gene better known for its role in preventing cancer also plays a key role in the developing embryo, where the gene prevents excessive growth of blood vessels, according to investigators at St. Jude Children's Research Hospital.

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

Stress test has less effect on blood vessels when hormone cortisol is blocked

Negative effects of the hormone cortisol on the inner lining of blood vessels, the endothelium, may explain how stressful events trigger heart attacks and other cardiovascular problems, according to a new study in the July 19, 2005, issue of the Journal of the American College of Cardiology.

New research suggests that accumulation of amyloid-beta peptides in cerebral blood vessels causes vascular damage in Alzheimer's disease

New research suggests that accumulation of amyloid-â peptides in cerebral blood vessels, as opposed to the brain itself, may be a more important pathological mediator of Alzheimer's disease. Two independent yet related articles describe such findings in the August issue of The American Journal of Pathology.

Chronic Obstructive Pulmonary Disease (COPD) rates in women skyrocket

The death rate for one of the most lethal diseases in North America has skyrocketed for women in the last 20 years, and a team of researchers from the University of British Columbia and the B.C. Centre of Excellence for Women's Health wants to find out why.

New discovery could help in the fight against cancer

University of Michigan researchers have figured out one more component in cancer cells' aggressive growth - and hope that knowledge can help kill the cells.

New finding has potentially major implications for anti-angiogenic therapy

Scientists supported by the National Institute of Dental and Craniofacial Research (NIDCR) have added a key new piece to the puzzle of how tumor cells induce new blood vessels to form and fuel their abnormal growth, a well-known process called angiogenesis.

New compound ruboxistaurin may decrease vision loss in diabete

A multicenter international study chaired by a Joslin Diabetes Center investigator and reported in the July issue of the American Diabetes Association's journal Diabetes brings hopeful news to the 18 million people in the United States -- and millions more worldwide -- with type 1 or type 2 diabetes.

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

Congenital central hypoventilation syndrome (CCHS) offers clues to SIDS, sleep apnea

Imagine raising a child who stops breathing when falling asleep - and has to be reminded to visit the bathroom after drinking a Big Gulp. That's the dilemma faced by parents of children born with congenital central hypoventilation syndrome (CCHS).

Lack of a blood clotting protein may protect against clogged arteries

Reporting in the July 18 issue of The Journal of Experimental Medicine, a group of scientists in Wurzburg, Germany show that the lack of a blood clotting protein may protect against clogged arteries with no risk of excessive bleeding.

Catchers' mitts do not adequately protect players' hands from injury

"We found signs of early blood vessel damage that could lead to significant symptoms and could end a player's career," said T. Adam Ginn, M.D., chief resident in orthopaedics at Wake Forest Baptist, and one of the study's researchers. "The gloves' current design does not protect the hand from trauma."

Insulin resistance drug with anti-inflammatory effects reduces risk factors

A drug, which reduces insulin resistance and also may have anti-inflammatory and other effects on blood vessels, lowered cardiovascular risk factors in patients with diabetes more than another diabetes medicine, even though both drugs improved blood sugar control equally, according to a new study (PDF) in the June 21, 2005, issue of the Journal of the American College of Cardiology.
