Nitric oxide synthase plays a role in peripheral vascular disease

The enzyme nitric oxide synthase plays a role in peripheral vascular disease, a common disease that impairs the mobility of 25 percent of people over the age of 50, according to a Yale study in the Proceedings of the National Academy of Sciences (PNAS).

UCI study helps identify one reason why women have lower stroke risk than men

Estrogen's role as an inhibitor of toxic-free radicals in cerebral blood vessels may be a key reason why premenopausal women have a lower stroke risk than men.

Coronary angioplasty increases risk of developing Alzheimer's disease

Boston University School of Medicine (BUSM) researchers have discovered that patients who have either coronary artery bypass graft surgery or coronary angioplasty are at an increased risk of developing Alzheimer's disease.

New drug CX717 can temporarily improve performance and reverse the effects of sleep deprivation

Research in monkeys suggests that a new drug can temporarily improve performance and reverse the effects of sleep deprivation on the brain, which would be a breakthrough in helping shift workers, health professionals, military personnel and others who must function at top performance in spite of sleep deficits.

Protein Sirt1 points to new therapies for type 2 diabetes

Opening the possibility of new therapies for type 2 diabetes, researchers at Washington University School of Medicine in St. Louis have found that a protein called Sirt1 enhances the secretion of insulin in mice and allows them to better control blood glucose levels. Their study appears in the August 17 issue of Cell Metabolism.

Researchers have found a signal that could lead to earlier detection and treatment of ovarian cancer

The Penn State team of scientists led by principal investigator Kathleen M. Mulder, Ph.D., professor of pharmacology, and working in conjunction with a researcher from the Center for Cancer Research, National Cancer Institute in Bethesda, Md., studied "km23," a protein that helps to direct protein traffic in the cell.

Family-based treatments are effective for substance abuse

Family-based treatments are effective for substance abuse and conduct disorders in children and adolescents, according to a new, ten-year research review released this week. The treatment also helps reduce the behavior problems associated with attention deficit hyperactivity disorder (ADHD) and shows promise in treating depression and anxiety.

Researchers find drug targets for treating metabolic syndrome

Ongoing studies by researchers at UT Southwestern Medical Center and other institutions have uncovered the biochemical basis of many of the factors contributing to what is known as the metabolic syndrome, suggesting potential new drug targets for treating the condition.

Alternative to Cox II inhibitors

After the failure of cox II inhibitors such as Vioxx, osteoarthritis patients and their doctors are faced with a lack of alternative therapies. The Orthokine-therapy means knee-injections of IL-1Ra protein, obtained from the patient's blood.

Firefly protein lets researchers monitor molecule known as IKK (for IKappa kinase) linked to cancer

Scientists have used a glowing protein from fireflies to observe the activity of a molecule that is an important target for new drugs to treat cancer, autoimmune diseases and several other disorders.

Study results reaffirm cyclin D1 as a candidate target for molecular therapeutic control of breast tumor development

For about a decade, scientists have recognized that many cases of hereditary breast cancer result from a mutation of a specific gene called BRCA1, which, in its normal state, helps keep tumor formation in check. About five to 10 percent of breast cancer cases arise from these genetic miscues, about half of which are linked to the abnormal functioning of BRCA1.

Scientists identify protein that may inhibit cellular movement

Scientists from the University of North Carolina at Chapel Hill School of Medicine and the UNC Lineberger Comprehensive Cancer Center have identified a protein that may inhibit cellular movement, or migration.

Research to investigate new drug for Parkinsons disease

Researchers at the University of Sydney have received a grant to investigate the potential of a new drug to treat the abnormal posture and balance that affects people with Parkinson's disease ultimately confining them to a wheelchair.

Potential new target for cannabis-derived drugs as a treatment of inflammatory bowel disease

Researchers investigating anecdotal evidence that cannabis relieves some of the symptoms of inflammatory bowel disease (IBD) have discovered a potential new target for cannabis-derived drugs for treatment of the disease.

Protein called cyclin D1 disrupts BRCA1's normal role as a cancer inhibitor

For about a decade, scientists have recognized that many cases of hereditary breast cancer result from a mutation of a specific gene called BRCA1, which, in its normal state, helps keep tumor formation in check. About five to 10 percent of breast cancer cases are linked to genetic miscues, about half of which are linked to BRCA1.

Controlling the expression of genes by turning them on or off could produce a drug for the treatment or cure of almost any disease

A new technique aimed at directly controlling the expression of genes by turning them on or off at the DNA level could lead to drugs for the treatment or cure of many diseases, say researchers at UT Southwestern Medical Center.

Researchers reveal secret of key protein in brain and heart function

Brown University biologists have solved the structure of a critical piece of synapse-associated protein 97 (SAP97) found in abundance in the heart and head, where it is believed to play a role in everything from cardiac contractions to memory creation. Results are published in The Journal of Biological Chemistry.

Cancer biology, pharmacology and engineering combine to create cancer smart bomb

Imagine a cancer drug that can burrow into a tumor, seal the exits and detonate a lethal dose of anti-cancer toxins, all while leaving healthy cells unscathed.

Single prenatal dose of methamphetamine enough to cause long-term neurodevelopmental problems in babies

In research published in the August issue of Free Radical Biology and Medicine, U of T pharmacy and pharmacology professor Peter Wells and his colleagues determined that exposing pregnant mice only once to methamphetamine led to delivery of offspring with long-term neurodevelopmental problems, including reduced motor co-ordination.
