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 confirms that COX-2 inhibitors predispose people to cardiovascular disease

After nearly 13 years of study and intense debate, a pair of new papers from the Perelman School of Medicine, at the University of Pennsylvania have confirmed exactly how a once-popular class of anti-inflammatory drugs leads to cardiovascular risk for people taking it.

FDA approves Novartis’ Afinitor for treatment of renal angiomyolipomas and TSC

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.

Dark chocolate may reduce risk of cardiovascular disease

Chocolate, considered by some to be the "food of the gods," has been part of the human diet for at least 4,000 years; its origin thought to be in the region surrounding the Amazon basin. Introduced to the Western world by Christopher Columbus after his fourth voyage to the New World in 1502, chocolate is now enjoyed worldwide. Researchers estimate that the typical American consumes over 10 pounds of chocolate annually, with those living on the west coast eating the most. Wouldn't it be great if only chocolate were considered healthy?

Perivascular fat tissue may influence onset of atherosclerosis

Researchers at UC have confirmed that fat surrounding the outside of arteries in humans-particularly the left coronary artery-may influence the onset of coronary artery disease, or atherosclerosis, which is the leading cause of death in the U.S.

Large doses of vitamin C may moderately reduce blood pressure

Taking large doses of vitamin C may moderately reduce blood pressure, according to an analysis of years of research by Johns Hopkins scientists. But the researchers stopped short of suggesting people load up on supplements.

Therapeutic hypothermia reduces in-hospital deaths among sudden cardiac arrest patients

Forced body cooling known as therapeutic hypothermia has reduced in-hospital deaths among sudden cardiac arrest patients nearly 12 percent between 2001 and 2009, according to a Mayo Clinic study being presented at the upcoming American Academy of Neurology 2012 Annual Meeting in New Orleans.

Novel system for 3D reconstruction and examination of tissues at microscopic resolution

Researchers have developed a novel, easy-to-use system for three-dimensional (3D) reconstruction and examination of tissues at microscopic resolution, with the potential to significantly enhance the study of normal and disease processes, particularly those involving structural changes. The new approach, using conventional histopathological methods, is described in the May issue of The American Journal of Pathology.

Eye test to detect heart disease early

Scientists at the University of Edinburgh have developed the test which scans blood vessels in the retina at the back of the eyes. They are now launching a study involving more than 1,000 patients to see if the test is reliable.

First large study to examine age, gender and sibling history on stroke risk

If your brother or sister had a stroke, you may be at least 60 percent more likely to have one too, according to research reported in the American Heart Association journal Circulation: Cardiovascular Genetics.

Study provides guidelines on how to combine antiangiogenic drugs with nanotherapeutics

Combining two strategies designed to improve the results of cancer treatment - antiangiogenesis drugs and nanomedicines - may only be successful if the smallest nanomedicines are used. A new study from Massachusetts General Hospital (MGH) researchers, appearing in Nature Nanotechnology, finds that normalizing blood vessels within tumors, which improves the delivery of standard chemotherapy drugs, can block the delivery of larger nanotherapy molecules.

Bare platinum coils vs. newer gel-coated coils for aneurysm treatment

Approximately 6 million Americans have brain aneurysms, a condition that occurs when a weak or thin spot develops on a blood vessel in the brain causing it to balloon. Often, these do not cause symptoms and go undetected, but every year an estimated 30,000 Americans experience a ruptured aneurysm that bleeds into the brain causing a life threatening injury.

Successful aneurysm treatment may not improve quality of life

Patients with unruptured brain aneurysms have significant reductions in several areas of quality of life—especially physical functioning, reports a study in the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
