Cardiovascular disease: diet, nutrition and emerging risk factors

Despite improvements in death rates from cardiovascular disease (CVD) around the world, CVD remains a leading cause of death and ill health in the UK, where death rates are amongst the highest in the world. Reducing death rates from this disease remains high on the Government’s agenda, yet attention to the classical risk factors may not provide all the answers.

Tissue engineering to grow bone, ligaments and cartilage

A future in which laboratory-grown organs and stimulated growth of muscle, bones and nerves could play a major role in treating medical conditions was revealed at a recent Tissue Engineering Symposium at Wake Forest University Baptist Medical Center.

Researchers discover mechanism by which tumours support their own growth

In a recent issue of the American Journal of Pathology, the Bremen researchers report their findings on a signalling molecule called "High Mobility Group Protein B1" (HMGB1). As a signal sent by tumour cells HMGB1 proteins induce sprouting of blood vessels that supply tumours with oxygen, thus promoting tumour growth.

Moderate levels of exercise may not be enough to control mild hypertension

Moderate levels of exercise may not be enough to control mild hypertension in men and women over age 55, the age group most at risk of later developing potentially fatal heart failure, a new four-year study reports. The findings by researchers at Johns Hopkins, to be published in the journal Archives of Internal Medicine online April 11, call into question the effectiveness of national guidelines on exercise for lowering blood pressure in older people.

The liver may produce most of the body's good cholesterol

Research in mice suggests that the liver may produce most of the body's "good" cholesterol, an unexpected finding that might one day help scientists develop new treatments to raise levels of this heart-protecting molecule in humans.

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.

Heart transplant patients benefit from new technology

New technology for cardiac transplant patients indicates a patient's risk of organ rejection with a simple blood test. News of this revolutionary testing method will be presented today at the International Society for Heart and Lung Transplantation's (ISHLT) Annual Meeting and Scientific Session in Philadelphia.

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.

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.

Method of gene therapy accurately corrects mutations in disease-causing genes

Harnessing the strength of a natural process that repairs damage to the human genome, a researcher from UT Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes.

Canada spends more on stem cell research

Canadian Justice Minister Irwin Cotler gave Canadian stem cell research an extra boost with the announcement of $5.3 million in annual funding.

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.

Natural killer cells could lead to new Hepatitis treatments

Researchers have discovered that natural killer T (NKT) cells, the immune system's sentinels, patrol the labyrinthine blood vessels of the liver for invaders or signs of tissue damage and demonstrate a dogged behavior not seen before in other T cells.

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.

Chemoembolization, first-line treatment for liver cancer

New research by Jeff Geschwind, M.D., director of interventional radiology and associate professor at Johns Hopkins University School of Medicine, has shown that liver cancer patients, most of whom have inoperable tumours, could benefit from chemoembolization, a nonsurgical treatment option that delivers a high-dose of chemotherapy to the tumour while decreasing blood flow through the arteries feeding the tumour, known as embolization.

Study shows connection of varicose veins to chronic pelvic pain

Research presented today at the Society of Interventional Radiology's 30th Annual Scientific Meeting found that 16 percent of women with varicose veins in their legs simultaneously had ovarian varicose veins -- a common but often under-diagnosed cause of chronic pelvic pain.

Blood pressure control suggests new approach to hypertension therapy

The kidneys have long been known to play a major role in many cases of high blood pressure, but a new study by researchers at Duke University Medical Center reveals that the body's control of blood pressure depends as much on other organs in the body.

Airway inflammation boosts infarction damage

Epidemiological studies show that the incidence of cardiovascular disease (CVD) complications are increased in long standing cases of asthma. Historically, the complications are often attributed to the chronic drug therapy used to treat asthma.
