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

Drinking wine or beer has same result: higher blood pressure

Whether the drink of choice is a frosty beer or a full-bodied red wine, the effect is the same – higher blood pressure, according to research reported in Hypertension: Journal of the American Heart Association.

Nanoparticles reveal tiny cancerous tumors

Specially designed nanoparticles can reveal tiny cancerous tumors that are invisible by ordinary means of detection, according to a study by researchers at Washington University School of Medicine in St. Louis.

Getting coronary bypass patients back on their feet sooner

Often after coronary bypass graft surgery, patients suffer more pain in their leg than any other part of the body. The pain is due to the harvesting of a healthy blood vessel from the leg to construct the bypass graft. Traditionally, the vein was removed with a long incision that may stretch from ankle to groin. Many patients may not be aware there is an alternative.

Cardiac stem cells come closer to clinic

The laboratory of MDA grantee Kenneth Chien at the University of California-San Diego announced in a recent issue of Nature that its researchers have discovered in the hearts of mice, rats and humans a new type of stem cell that can become a mature cardiac cell.

Fifteen-year hunt uncovers gene behind pseudothalidomide syndrome

A team of scientists from Colombia, the United States and elsewhere has successfully completed a 15-year-plus search for the genetic problems behind the very rare Roberts syndrome, whose physical manifestations often include cleft lip and palate and shortened limbs that resemble those of babies whose mothers took thalidomide during pregnancy.

THC in marijuana may prevent hardening of the arteries

A study by Dr. Francois Mach, University Hospital Geneva, Switzerland, and colleagues has found that low doses of the main active ingredient in marijuana slowed the progression of hardening of the arteries in mice, but some experts are stressing that the finding does not mean people should smoke marijuana in hopes of getting the same benefit.

Gene therapy shows effect in heart patients

The first double-blind, placebo-controlled randomized trial of VEGF gene injections into the heart muscle of patients with coronary artery disease with the intention of spurring growth of new blood vessels showed significant effects on heart wall motion, although blood flow was not significantly better in treated patients, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Researchers have identified a new clinical syndrome

Researchers have identified a new clinical syndrome that produces serious and sometimes fatal symptoms in a variety of seemingly unrelated diseases. The syndrome, described in the April 6 issue of the Journal of the American Medical Association, is caused by hemolysis, the destruction of red blood cells.

Dallas heart study researchers find no link between Lp(a), calcium

The latest findings from the historic Dallas Heart Study have ruled out one of the most prominent explanations of why elevated levels of a fat-carrying protein called "lipoprotein(a)" lead to increased risks for heart attacks among whites but not among African-Americans.

First evidence that preeclampsia can leave a persistent and potentially fatal imprint in the pulmonary circulation of the fetus

Children born of mothers who had preeclampsia during their pregnancy are more likely to have pulmonary hypertension than similar children born from normal pregnancies, according to a study conducted in Bolivia by Swiss and Bolivian researchers.

Gene mutation protecting against malaria linked to prostate cancer incidence in African-American men

Research from the University of Cincinnati College of Medicine suggests that the 60 percent greater incidence of prostate cancer among African-American men is related to a gene mutation developed generations ago in West Africa as nature's way of providing protection from the malaria infection endemic in that part of the world.

Immune cells in the liver travel in the liver's blood vessels with surprising speed and agility

Scientists at New York University School of Medicine viewing the actual journey of immune cells in the liver have found that these cells travel in the liver's blood vessels with surprising speed and agility.

Implantable medical device that lowers blood pressure

Doctors at the University of Rochester Medical Center are the first in the nation to implant an investigational medical device that lowers blood pressure by activating the body's natural blood pressure regulation systems.

Cranberry juice may help protect against heart disease

Protection against a wide variety of diseases is among the many benefits of a diet high in whole fruits and vegetables. Cranberries over the years have been identified with preventing or ameliorating urinary tract infections and playing a positive role gum disease, ulcers and even cancer.

Aspirin safer than Warfarin for treating blocked arteries

National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH), have shown for the first time that aspirin works as well as warfarin in reducing blood clotting. Until now doctors have lacked good evidence for choosing one therapy over the other.

Marker for new blood vessel formation in tumors

In a paper in this month's freely-available online global health journal PLoS Medicine, Roland Haubner and colleagues describe how a compound they have developed can be used together with highly sensitive positron emission tomography (PET) scanning to measure the amount of new blood vessel growth in some tumors.

Discovery of key molecule that controls the growth, spread and survival of pancreatic cancer cells

Pancreatic cancer kills 30,000 Americans every year. Not only is there no cure, but there are no effective treatments. That may change if a new finding by Mayo Clinic researchers continues to show promise.

Beneficial effects of Alpha-Linolenic acid in walnuts

The recently-announced USDA dietary guidelines stress the need for consumers to be more aware of the benefits of polyunsaturated essential omega-3 fatty acids in order to achieve a healthy diet. Many people look to fish, such as salmon, for omega-3s, but plant sources such as walnuts are also specifically noted in the USDA recommendations.

Active brains stave off Alzheimer's signs

Mice who keep busy playing with toys also keep their brains and bodies active; more importantly, they also have lower levels of the peptides and brain plaques associated with Alzheimer's disease, compared to mice raised in environments not "enriched" with chew toys, running wheels,and tunnels, according to a new study in the 11 March issue of the journal Cell.

First genetic marker to help identify ruptured brain aneurysm

Mayo Clinic researchers have discovered a genetic marker that may pave the way for a fast, inexpensive blood test to predict one type of deadly stroke that strikes 30,000 people in the United States annually.
