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

Angiogenesis inhibitor molecules defend against the development and spread of cancer

Research led by investigators at Beth Israel Deaconess Medical Center (BIDMC) helps explain how a group of angiogenesis inhibitor molecules serve as an important defense mechanism against the development and spread of cancer, offering key insights into why cancerous tumors grow at different rates among different individuals.

Potential treatments for neurofibromatosis

Scientists at the Indiana University School of Medicine are closing in on potential treatments for neurofibromatosis, a genetic disease that afflicts 100,000 Americans with nerve tissue tumors, some of which become cancerous.

Mitochondria - the energy factories in our cells - can sustain a cancer

University of Glasgow scientists have discovered how mitochondria - the energy factories in our cells - can sustain a cancer, reporting their findings in a new study published in Cancer Cell.

New understanding of the causes for symptoms of sickle cell disease

A new understanding of the causes for symptoms of sickle cell disease, a condition affecting one in every 600 African-Americans, has resulted from a study by researchers at Duke University Medical Center and Howard Hughes Medical Institute (HHMI). Their findings may lead to a new, more direct method for treating the disease, they said.

Physical traits, genetic test help with early diagnosis of aneurysm syndrome

A research team led by Johns Hopkins doctors has defined the physical traits and genetic basis of a new aortic aneurysm syndrome that is extremely aggressive and can cause death in early childhood. Early diagnosis of the syndrome and rapid surgical repair of the swollen aorta can save lives, the researchers report in the Jan. 30 advance online section of Nature Genetics.

Cardiac rehabilitation and secondary prevention protocols to imperative prevent recurrent heart attacks

Physicians should aggressively encourage patients to exercise and follow cardiac rehabilitation and secondary prevention protocols to prevent recurrent heart attacks, the American Heart Association recommends in its updated scientific statement on cardiac rehabilitation and secondary prevention of coronary heart disease.

Warfarin combined with NSAIDs or COX-2 inhibitors increased risk of upper gastrointentinal hemorrhage

Patients taking warfarin at the same time as selective COX-2 inhibitors or nonselective NSAIDs have an increased risk of hospitalization for upper gastrointestinal (GI) hemorrhage, according to Canadian researchers analyzing health care databases.

Invasive procedures do not necessarily improve survival for heart patients

Invasive procedures, often given to patients as soon as they are admitted to hospital with a life-threatening heart condition, do not necessarily improve survival, finds a study published on bmj.com today.

Heart patients with gastrointestinal complications should use low doses of aspirin combined with drugs that treat stomach ulcers

Physicians are challenged in treating heart patients who may be at high-risk for gastrointestinal bleeding from aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs). Factors that place patients at high-risk include a history of ulcers or gastrointestinal complications such as bleeding, increased age and congestive heart failure.

Research leads to new antiangiogenic drugs

Scientists have uncovered critical information that may lead to an urgently needed method for effective monitoring of antiangiogenic cancer therapies.

Macular degeneration patients benefit from self-management training

A 12-hour self-management program for individuals with advanced age-related macular degeneration (AMD) leads to lasting improvements in mood and function, especially in depressed patients, and decreases the development of clinical depression in AMD patients over time, according to a University of California, San Diego (UCSD) Shiley Eye Center study published in the January 2005 Archives of Ophthalmology.

Novel approach to bioengineer artificial skin for burn victims

Each year more than 45,000 Americans suffer burns serious enough to require a hospital stay, according to the American Burn Association. While the traditional therapy of using skin grafts to cover burn sites has improved, a number of problems including scarring, infection and poor adhesion remain.

Pegaptanib (Macugen) is an effective treatment for neovascular age-related macular degeneration

Results from two concurrent, prospective, double-blind, multi-center clinical trials show that pegaptanib (Macugen), an anti-vascular endothelial growth factor therapy, is an effective treatment for neovascular age-related macular degeneration (AMD), according to a paper in the Dec. 30 issue of the New England Journal of Medicine. Macugen was approved by the Food and Drug Administration on Dec. 17.

Brisk walks substantially improve blood vessel function both before and during the hours after eating a fatty meal

A 90-minute walk lowered triglycerides and improved blood vessel function in a small group of lean and obese men, and the benefits persisted into the following day, even after participants ate a fatty meal, according to a new study in the Dec. 21, 2004 issue of the Journal of the American College of Cardiology.

Timing of radiation and antiangiogenic therapy impacts treatment effectiveness

Agents designed to attack blood vessels that feed a growing tumor are effective against tumor growth in laboratory experiments. However, results of early clinical trials with these inhibitors have not yet exhibited the same success observed in animal models.

Macugen approved for the treatment of neovascular (wet) age-related macular degeneration (AMD)

Eyetech Pharmaceuticals and Pfizer have announced that the U.S. Food and Drug Administration (FDA) approved Macugen (pegaptanib sodium injection) for the treatment of neovascular (wet) age-related macular degeneration (AMD), an eye disease associated with aging that destroys central vision.

Study supports the use of the internal mammary artery in coronary artery bypass grafting

Long-term follow up with heart bypass patients treated in Veterans Affairs hospitals shows that 85 percent of left internal mammary artery grafts and 61 percent of vein grafts remain open (patent) after 10 years, and that these grafts are more likely to offer long-term success when they are attached to larger arteries on the heart, according to a new study in the Dec. 7, 2004 issue of the Journal of the American College of Cardiology.

Noninvasive test of blood flow response may reveal early coronary disease

Chest pain patients who have abnormal coronary blood vessel function also have less responsive blood vessels in their fingertips, suggesting that a type of fingertip probe could become a useful screening tool, according to a new study in the Dec. 7, 2004 issue of the Journal of the American College of Cardiology.
