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

Health-care workers should undergo preventive drug treatment if exposed to HIV on the job

Doctors, nurses and other health-care providers have worried about HIV exposure since the AIDS epidemic first began in the early 1980s. Since the virus that causes AIDS is transmitted through blood, a simple needle stick could infect anyone treating a patient.

Link between growth of blood vessels critical to spread of cancer and copper in our bodies

Growing new blood vessels from existing ones - a process called angiogenesis - is important in growth, development and wound healing. But it also enables the spread of tumors throughout the body, so researchers have been scrambling for ways to stop angiogenesis in the fight against cancer.

Common painkillers raise mens' risk of hypertension

Researchers in the United States believe that regular use of common painkillers such as Acetaminophen (paracetomol), ibuprofen and aspirin, increases the risk of high blood pressure and consequently heart disease in men.

Gene therapy shows promise as treatment for diseased lower limbs at risk for amputation

New research suggests that gene therapy is a safe treatment method to explore in patients whose lower limbs are at risk for amputation because of poor circulation caused by blocked blood vessels.

Why are African American women more likely than White women to die from breast cancer?

Why are African American women 1.5 to 2.2 times more likely than White women to die from breast cancer, despite their lower incidence of the disease? Is it solely because they have less access to medical care? Maybe not, according to a new analysis that will appear in an upcoming issue of the International Journal of Surgery.

Health care professionals should focus on women's lifetime heart disease risk

The 2007 Guidelines for Preventing Cardiovascular Disease in Women -- published today in a special women's health issue of Circulation: Journal of the American Heart Association -- also include new directions for using aspirin, hormone therapy and vitamin and mineral supplements in heart disease and stroke prevention in women.

Cancer breakthrough - first treatment to directly target tumor supply

For the first time, physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center in New York City have demonstrated in patients the ability of an antibody to directly target the blood supply of a wide variety of tumors, leaving healthy tissues unharmed.

FDA approves temporary limb salvage shunt

The U.S. Food and Drug Administration (FDA) has cleared for U.S. marketing a vascular shunt, a medical device that can help save the arms and legs of soldiers critically injured in combat as well as individuals in other trauma settings and emergency situations.

Stents benefit people at high risk of stroke due to blocked blood vessels in the brain

For the study, researchers in Beijing evaluated 213 people who had received a stent, which is an expandable wire form used to open up a narrowing or totally obstructed blood vessel.

New understanding of blood pressure gene could lead to new treatments

Research by scientists at UCL (University College London) has clearly demonstrated for the first time the structure and function of a gene crucial to the regulation of blood pressure. The discovery could be important in the search for new treatments for illnesses such as heart disease, the UK's biggest killer.

Dll4 signalling through Notchi regulates formation of tip cells during angiogenesis

All tissues, sick and healthy alike, need a blood supply to survive and grow. The key to many medical problems, like preventing tumour development, is therefore to obstruct the spread of the blood vessels. Research scientists at Karolinska Institutet have now discovered a heretofore unknown mechanism for how the body links together its blood vessels.

FoxOs shown to be potential new targets for cancer drugs

In an elegant, multiple-gene knockout experiment, a team of Boston scientists has discovered that a trio of molecules, called FoxOs, are fundamentally critical in preventing some cancers, maintaining blood vessel stability, and in keeping blood-forming stem cells healthy.

Lung neutrophils produce histamine in significant quantities

In a surprise finding, scientists have discovered that histamine, the inflammatory compound released during allergic reactions that causes runny nose, watery eyes, and wheezing, can be produced in large amounts in the lung by neutrophils, the white blood cells that are the major component of pus.

Stem cells derived from human amniotic fluid appear to offer many of the benefits of embryonic stem cells

...including the ability to grow into brain, muscle, bone and other tissues -- according to a study published in the Jan. 7 online edition on the journal Nature Biotechnology, the Washington Post reports.

Common-sense measures to stop ICU infections

Hospitals will quickly slash the rate of common, costly and potentially lethal catheter-related bloodstream infections in their intensive care units (ICUs) by using cheap, low-tech, common-sense measures like hand washing, timely removal of unneeded catheters, and use of sites other than the groin to place lines when possible, according to a report from safety experts at Johns Hopkins in the New England Journal of Medicine.
