Blood Vessel News and Research

RSS

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

Heart bypass gets new source for replacement blood vessels

The search for a stable, renewable source of blood vessels, especially for potential use in heart bypass surgery, has reached a milestone at the State University of New York at Buffalo.

ACE inhibitors not needed for many heart disease patients

Many heart disease patients who are already receiving state-of-the-art therapy do not benefit from additional treatment with angiotensin converting enzyme (ACE) inhibitors, according to results of a new study funded by the National Heart, Lung, and Blood Institute (NHLBI).

Walnut supplementation favorably affects cholesterol and other lipids that are signs of cardiovascular risk

A Penn State study has shown that a diet rich in alpha-linolenic acid from walnuts, walnut oil and flaxseed oil not only lowered bad cholesterol but also decreased markers for blood vessel inflammation in men and women representative of typical Americans at cardiovascular risk.

Second successful human ovarian to arm transplant in the world

A new study finds surgery to transplant an ovary to the upper arm is feasible and preserves hormonal function in women undergoing treatment for cervical cancer.

Protein important to nerve development serves the dual purpose of stimulating the growth of blood vessels

The discovery opens the possibility that blood vessel growth (angiogenesis) one day may be induced, or stymied, for therapeutic use against heart disease, cancer, and other illnesses, according to Dean Y. Li, M.D., Ph.D., associate professor of internal medicine in the U of U School of Medicine's Division of Cardiology.

Scientists have found that a protein present in normal body tissues can prevent tumour growth

A team led by Dr Dave Bates, British Heart Foundation Lecturer, and Dr Steve Harper, Senior Research Fellow in the Microvascular Research Laboratories, in the Department of Physiology at Bristol University, have discovered that a type of vascular endothelial growth factor (VEGF) found in normal tissue, including blood, can prevent cancers from growing.

New evidence to explain why mental function becomes less efficient with ageing

Dementia and milder forms of loss of mental ability affects millions of older people every year, but the causes are unclear. Previous research using brain scanning has shown that brain shrinkage and changes in the brain's white matter 'wiring', are associated with mental function slowing down in old age.

Study supports earlier findings, and even showed a significantly higher prevalence of periodontal diseases in cardiac patients

Research is racing to help healthcare professionals further understand how periodontal diseases are linked to cardiovascular disease.

Potential new treatment strategy against metastatic cancer cells

A team of scientists at The Scripps Research Institute has identified a potential treatment strategy against metastatic cancer cells that has never been tried before.

Two hearts are better than one for toddler

Camila Gonzalez now has two hearts beating separate rhythms inside her tiny chest. At 22 months of age, she became the youngest child in the United States to receive a donor’s heart while also retaining her original one.

Breakthrough discovery in treating narrowed arteries

A breakthrough discovery by Heart and Stroke Foundation researcher Dr. Michael Kutryk that harnesses the body’s own natural defenses to fight narrowing of the arteries has been recognized as “a glimpse into the future” and “potentially one of the biggest advances in cardiology to date”.

Investigational drug for pulmonary hypertension may improve the quality of life for patients with scleroderma and lupus

An investigational new drug for pulmonary hypertension may improve the quality of life for thousands of patients with scleroderma, lupus, and other associated connective tissue diseases, according to research presented this week at the American College of Rheumatology Annual Scientific Meeting in San Antonio, Texas.

Researchers stimulate the body to repair tissue damaged by peripheral arterial obstructive disease

Duke University Medical Center researchers have shown that they can stimulate the body to produce its own naturally occurring growth factors to promote blood vessel growth into tissue damaged by peripheral arterial obstructive disease (PAOD).

New research points to potential new treatments for sickle cell disease

New research from the University of North Carolina at Chapel Hill reveals why red blood cells from people with sickle cell disease are stickier than healthy red cells, pointing the way to potential new treatments for sickle cell disease.

Biomedical engineers receive $11.5 million to study how white blood cells navigate

We all know the power of touch: A whack on the skull – or a hug – can convey more information than other forms of communication ever can. It turns out the same is true inside our bodies

Study raises important questions about the use of drugs that promote or prevent angiogenesis

Dartmouth Medical School cardiology researchers have discovered a new mechanism for what drives the growth of muscle tissue in the lining of injured heart vessels that can eventually lead to blockage.

Researchers discover mechanism that may help to explain how angiogenesis inhibitors work on normal, blood vessel-forming endothelial cells

Northwestern University researchers have discovered a mechanism that may help to explain how angiogenesis inhibitors work on normal, blood vessel-forming endothelial cells, but not on insidious, aggressive melanoma cells that masquerade as endothelial-like cells by forming their own vascular networks, called "vasculogenic mimicry."

Research shows C. botulinum uses SONO to detect nitric oxide

A deadly bacterium's defense against a mortal molecular enemy illuminates the origins and structure of a vital protein involved in human cell signaling, University of Texas Medical School scientists report in Science Express.

Women with the Polycystic Ovary Syndrome (PCOS) are at greatest risk for diabetes and coronary artery disease

A new position statement issued today by the American Association of Clinical Endocrinologists (AACE) states that women with the Polycystic Ovary Syndrome (PCOS) are at greatest risk for diabetes and coronary artery disease.

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.
