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.

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.

Researchers discover new mechanism responsible for blood vessel tumors that cause facial deformities

Researchers have discovered a new mechanism responsible for the growth of blood vessel tumors that can cause facial deformities in infants and young children, paving the way for an antibody-based treatment to remove cells that fuel the tumors’ growth.

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.

Discovery of key molecular step which allows cancer cells to move to different parts of the body

Researchers at The University of Texas M. D. Anderson Cancer Center have figured out a key molecular step by which a cancer cell can unhook itself from the mesh weave of other cancer cells in a tumor, and move away to a different part of the body - the process, known as metastasis, that makes cancer so dangerous.

Understanding how kidneys absorb protein from urine will help fight kidney disease in diabetics

A team of University of Queensland researchers led by Dr Philip Poronnik, a senior lecturer in the School of Biomedical Sciences, is unravelling the molecular processes in the kidney which retrieves proteins.

Research findings may help stave off full-blown diabetes

A new study by researchers at Joslin Diabetes Center sheds light on the key mechanisms by which new pancreatic beta cells normally form in response to insulin resistance. These findings may some day help researchers devise ways of staving off full-blown diabetes.

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.

Drug combo may have a greater impact on cancer development

Cancer researchers have long suggested that new targeted drugs may work best when paired with other therapies. In a new study published today in Cancer Research, scientists have taken some of the first steps to demonstrate this synergy in mouse and cell line models.

Benefit of using clot-busting drug tissue plasminogen activator (tPA) for ischemic stroke

An independent review of data from a landmark clinical trial has validated the benefit of using the clot-busting drug tissue plasminogen activator (tPA) for ischemic stroke, when given within three hours of symptom onset under a strict treatment protocol.

FDA approves stent that treats blockages in the main blood vessel leading to the brain

The U.S. Food and Drug Administration has approved a stent for use in opening blocked arteries in the neck. The new stent is intended to prevent stroke by treating blockages in the carotid artery, the main blood vessel leading to the brain.

Study suggests that patients with pulmonary arterial hypertension may benefit from Thelin therapy

Encysive Pharmaceuticals today announced the presentation of data from a clinical study of Thelin(TM) (sitaxsentan) in pulmonary arterial hypertension (PAH), at the European Society of Cardiology Annual Congress in Munich.

Alcohol in moderation maintains a healthy heart and reduces tissue damage following a heart attack

For years researchers have tried to determine why the French have such a lower rate of cardiovascular disease, given the amount of fat consumed in their diets.

Researchers explain dual effects of ginseng

In work that emphasizes the need for stronger regulations of herbal drugs, an international team of MIT scientists and colleagues has unraveled the yin and the yang of ginseng, or why the popular alternative medicine can have two entirely different, opposing effects on the body.

Surgery for angina in the elderly provides long-term mortality

Elderly people who undergo surgery or angioplasty to treat chest pain fare just as well long-term as those treated with medication, researchers report in Circulation: Journal of the American Heart Association.

Researchers to conduct a series of studies on human circulation

Penn State College of Medicine researchers recently were awarded a five-year, $7 million grant from the National Heart, Lung and Blood Institute of the National Institutes of Health to conduct a series of studies on human circulation.

FDA clears device to remove blood clots from the brain in patients experiencing an ischemic stroke

An ischemic stroke occurs when a blood vessel in the brain is blocked by a blood clot which can impair brain function and cause severe disability or death. Of the 700,000 annual strokes in the US, approximately 83 percent (or 581,000) are ischemic. The Merci Retriever is a novel therapy that removes clots, restores blood flow and offers hope for ischemic stroke patients with no other options.
