Prevalence and physiological predictors of sleep apnea in patients with heart failure

Obstructive sleep apnea (OSA) and central sleep apnea (CSA) are not markedly decreased in heart failure (HF) patients managed with beta-blockers and spironolactone, reports a study in the March issue of Journal of Cardiac Failure, published by Elsevier.

Rarefaction for gene discovery

Researchers at Purdue University have found a way to save time, money and a little frustration in searches for specific genes that shed light on the biological processes associated with all forms of life.

Discovery of method to neutralize tumor growth in embryonic stem cell therapy

Researchers at the Hebrew University of Jerusalem have discovered a method to potentially eliminate the tumor-risk factor in utilizing human embryonic stem cells. Their work paves the way for further progress in the promising field of stem cell therapy.

Understanding why non-smokers develop lung cancer among research projects funded by Canadian Cancer Society

A new BC-based study aimed at understanding the genetic basis of lung cancer in people who have never smoked is being funded for approximately $379,000 by the Canadian Cancer Society.

Mushrooms may boost the body's natural immune system

The potential for mushrooms to fight influenza is being examined following United States research suggesting the body's natural immune response against viral infections and tumours is boosted through the consumption of white button mushrooms.

CT scans increase cancer risk estimates in multiply-imaged emergency department patients

Physicians should review a patient's CT imaging history and cumulative radiation dose when considering whether to perform another CT exam, according to researchers at Brigham and Women's Hospital, Boston, MA, and Washington University School of Medicine, St. Louis, MO.

Elevated level of certain protein in urine linked to increased risk for blood clots

Preliminary research suggests that higher than normal levels of the protein albumin in urine is associated with an increased risk for blood clots in the deep veins of the legs or lungs (venous thromboembolism; VTE), according to a study in the May 6 issue of JAMA, the Journal of the American Medical Association.

Study shows beneficial effects statins may have on gastrointestinal disorders

The commonly used prescription statin drugs may have a protective effect in the prevention of liver cancer and lead to a reduction in the need for gallbladder removals, according to two studies published in Gastroenterology.

Research shows why certain atherosclerotic lesions can turn deadly

A common misconception about arterial plaque is that it inevitably leads to a heart attack or a stroke. New research at Columbia University Medical Center, however, sheds light on why so few plaques in any given individual actually cause a problem. Furthermore, the research has identified a key protein that may promote the conversion from benign to dangerous plaques.

Estrogen plays a key role in how the brain processes sounds

The findings, published in today's issue of The Journal of Neuroscience, show for the first time that a sex hormone can directly affect auditory function, and point toward the possibility that estrogen controls other types of sensory processing as well.

Drugs designed to tackle endoplasmic reticulum stress might be useful in treating heart disease

Researchers say they have evidence to explain what separates your average blood vessel plaque from those that are at high risk for triggering the development of dangerous - even fatal - blood clots.

Research highlights importance of socializing over food

Sharing a meal in good company can stimulate the appetite - particularly among hospitalized seniors - according to a new University of Montreal study published in The Gerontologist.

New DEAR1 gene predicts local recurrence in early-onset breast cancer

A newly discovered gene known as DEAR1 is mutated in breast cancer and is an independent predictor of local recurrence-free survival in early-onset breast cancer, a research team headed by scientists at The University of Texas M. D. Anderson Cancer Center reports in the journal PLoS Medicine.

Scientists coax skin cells to behave like muscle cells and vice versa

Even cells aren't immune to peer pressure. Scientists at the Stanford University School of Medicine have now shown that skin cells can be coaxed to behave like muscle cells - and muscle cells like skin cells - solely by altering who they hang out with: the relative levels of the ingredients inside the cell.

Scientists create human monoclonal antibody that neutralizes the Hepatitis C virus

Taking aim at a leading cause of liver failure in the United States, a team of scientists at the Massachusetts Biologic Laboratories (MBL) of the University of Massachusetts Medical School (UMMS) has developed a human monoclonal antibody that neutralizes the Hepatitis C virus (HCV).

Snippet of RNA helps make individuals alike

"No two people are alike." Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are.

Researchers target telomeres to attack tumors

Hoping to develop more effective long-term attacks on cancer, researchers at the Indiana University School of Medicine are conducting the first human tests of a breast cancer drug regimen that includes a compound meant to force cancer cells to grow old and die.

Potential molecular target for new schizophrenia treatments

A study on schizophrenia has implicated machinery that maintains the flow of potassium in cells and revealed a potential molecular target for new treatments. Expression of a previously unknown form of a key such potassium channel was found to be 2.5 fold higher than normal in the brain memory hub of people with the chronic mental illness and linked to a hotspot of genetic variation.

Small molecules might block mutant protein production in Huntington's disease

Molecules that selectively interfere with protein production can stop human cells from making the abnormal molecules that cause Huntington's disease, researchers at UT Southwestern Medical Center have found.
