Researchers use PET/CT for molecular imaging of the heart

For the first time, researchers used positron emission tomography (PET)/computed tomography (CT) for imaging the subcellar function of the heart - from its subcellular function to its morphologic appearance. The results of the study were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Obesity is associated with an impairment of coronary circulatory function

A team of University of California, Los Angeles researchers found that positron emission tomography (PET) can provide important information on the relationship between heart function and obesity. Their findings were reported at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Cyr61 gene transfer appears potent in stimulation of myocardial angiogenesis

French scientists, examining the possibility of using nuclear medicine with gene therapy to fight heart diseases, reported their findings at the Society of Nuclear Medicine's 52nd Annual Meeting June 18–22 in Toronto.

Elevated C-reactive protein can foil diet's ability to lower cholesterol

If you have high levels of C-reactive protein (CRP), a marker in blood for inflammation that is strongly associated with heart disease, trying to lower your LDL-cholesterol through modest diet changes alone may not work.

Researchers use novel cocktail of cells to coax muscle tissue to develop its own vascular network

For years, a major obstacle has dashed the hopes of creating "replacement parts" for the human body: the lack of an internal, nourishing blood system in engineered tissues. Without it, thicker tissues can't thrive, which has confined tissue engineering's practical application to thin skin, which can recruit blood vessels from underlying tissue.

Many pitfalls of aging result from either older stem cells or stem cells responding to their older environment

Older people are more prone to infections and have a higher risk of developing leukemia, and now researchers at Stanford University School of Medicine have one hint as to why that may be.

Patients who need PET/CT scans should avoid drinking coffee

Patients who need a positron emission tomography (PET)/computed tomography (CT) procedure to evaluate known or suspected malignancies should lay off the java, according to research by Medhat M. Osman, M.D., Ph.D., assistant professor in the department of internal medicine's division of nuclear medicine and director of PET at Saint Louis University Hospital.

Study finds better long-term outcomes when surgeons place a bypass graft to all the territories of the heart that have significantly blocked arteries

Pointing out that not all coronary artery bypass operations are performed the same way or have equivalent outcomes, cardiothoracic surgeons at Cedars-Sinai Medical Center have found that patients who have blockages of multiple coronary arteries and undergo "complete revascularization" - grafting of arteries to restore blood flow to all affected territories of the heart - have consistently better long-term survival rates than those who have "incomplete revascularization."

Faulty defibrillators may mean surgery for thousands of cardiac patients

Surgery to replace possibly faulty implanted cardiac defibrillators may now be on the cards for thousands of cardiac patients.

Fish only good for expectant mums if mercury level is low

For years medical experts have argued, as fish can be harmful as well as healthy, and what advice to give people, particularly pregnant women, about how much is safe to eat.

First blood test to help predict a patient's risk for ischemic stroke

The U.S. Food and Drug Administration (FDA) has approved the first blood test designed to help predict a patient's risk for ischemic stroke, the most common type of stroke and one of the nation's leading causes of long-term disability affecting approximately 700,000 people per year.

Study shows why thiazolidinediones cause edema and helps understand role of kidneys in hypertension

In related discoveries with far-reaching implications for treating diabetes and understanding hypertension, University of Utah researchers have learned why thiazolidinediones (TZDs), a major anti-diabetes drug, cause edema and also have found a new pathway critical to fluid metabolism. Identification of this pathway may help understand fundamental mechanisms of blood pressure control.

Cardiovascular researchers at the University of Oregon use new environmental chamber to investigate the body's response to stress

A new research tool will allow University of Oregon scientists to replicate an extreme range of environmental conditions in their quest to test and understand the human body's response to everyday stresses.

Bipolar disorder more prevalent and costly than believed

The incidence of bipolar disorder in the general population is considerably higher than earlier studies have indicated, resulting in significantly less productivity and more days lost from work compared to the better known major depressive disorder, according to preliminary findings from a national survey presented today at the Sixth International Conference on Bipolar Disorder.

High-volume medical centers better at treating cancer

Patients with certain complex cancers fare better under the care of doctors and hospitals that do the most of that kind of surgery, a new review of studies finds.

Yet another proven benefit of tight glucose control for those with type 1 diabetes

New study results confirm, for the first time, that intensive treatment of diabetic patients results in a significantly lower risk of heart disease. In fact, it can cut the risk of cardiovascular disease nearly in half.

Specific genetic linkages to bipolar disorder

Despite an intensive effort, researchers have yet to identify the genes that cause bipolar disorder, yet the practical benefits of such a discovery could reap rich rewards for those suffering from the mental illness.

Findings may help scientists improve the existing vaccine for yellow fever

In one of the first molecular studies of the human antibody response to yellow fever, Howard Hughes Medical Institute (HHMI) researchers and their colleagues have found the crucial bit of virus that people's immune systems need to spot and quash this often-fatal re-emerging disease.

Chronic insomnia medicines have not yet been rigorously evaluated for long-term use

Many of the medications widely used to manage chronic insomnia have not yet been rigorously evaluated for long-term use, according to an independent scientific panel convened this week by the National Institutes of Health.
