Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
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.
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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
And, according to a second study published today by the same team, the difference doesn't appear to be related to Mexican-Americans' higher incidence of diabetes, which had been thought to raise their risk of a certain type of stroke.
The lack of a gene called LBP-1a in the mouse embryo prevents normal growth of blood vessels in the placenta. This finding suggests that a similar defect in humans could play a role in fetal growth retardation, infant mortality and spontaneous abortion.
In the largest and longest trial yet of a device called the Amplatzer ductal occluder, a duct that shunts blood flow away from the lungs during fetal development but sometimes fails to close after birth, was successfully closed in almost all patients, according to a new study in the Aug. 4, 2004, issue of the Journal of the American College of Cardiology.
