Connection found between allergic diseases and autoimmune diseases

A new study by researchers at Children's Hospital and Regional Medical Center and the University of Washington (UW) identifies a connection between allergic diseases such as atopic dermatitis, also known as eczema, and autoimmune diseases. The study was published in the April 1, 2007 edition of Nature Immunology.

Research holds promise for new techniques for pancreas cell manipulation

Replacing faulty or missing cells with new insulin-making cells has been the object of diabetes research for the last decade. Past studies in tissue culture have suggested that one type of pancreas cell could be coaxed to transform into insulin-producing islet cells.

Possible therapeutic target for Duchenne muscular dystrophy

In the April 1st issue of Genes & Development, Dr. Bruce Spiegelman (Dana Farber Cancer Institute) and colleagues identify a key genetic component of and possible therapeutic target for Duchenne muscular dystrophy.

Circadian genes may be involved in bipolar disorder

Disrupt the gene that regulates the biological clocks in mice and they become manic, exhibiting behaviors similar to humans with bipolar disorder, UT Southwestern Medical Center researchers have found.

Erectile dysfunction drugs may be better than nitroglycerin in protecting the heart after a severe heart attack

During a heart attack, the heart is deprived of oxygen, which can result in significant damage to heart muscle and tissue. After the attack, most patients require treatment to reduce and repair the damage and improve their chances of survival.

Nicotine use is highly addictive in primates

Tobacco dependence is the leading cause of mortality in Canada. Although most smokers express a desire to stop smoking, only a small number are able to succeed.

Study shows PanK2 enzyme within mitochondria is triggered by the first step in fatty acid breakdown

Just as homes have smoke detectors, cells have an enzyme that responds to a buildup of fatty acids by triggering the production of a key molecule in the biochemical pathway that breaks them down, according to investigators at St. Jude Children's Research Hospital. This provides the cell energy while reducing the chance that excess fatty acids will accumulate.

Fighting influenza with 40,000 blood samples

Four million people die every year from respiratory diseases such as viral influenza. For elderly people in particular, an infection can be dangerous. What is more, the flu vaccine is not as effective with this risk group as it is with younger people.

Novavax's pandemic flu vaccines show promise

Novavax, Inc.'s novel virus-like particle (VLP) vaccines have been shown to be effective in generating protection against pandemic influenza as well as cross protection against different strains of the virus in pre-clinical studies, according to data presented at the Phacilitate Vaccine Forum.

Modified skin cells that may help protect cultured skin substitutes from infection

Cincinnati burn researchers have created genetically modified skin cells that, when added to cultured skin substitutes, may help fight off potentially lethal infections in patients with severe burns.

Inhibiting a particular cancer-causing gene improves radiation effectiveness

Inhibiting a particular cancer-causing gene can enhance the cell-killing effects of radiation, a team of radiation oncologists and cancer biologists at the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia has found.

Potential for first diagnostic DNA test to guide antidepressant treatment

Treatment of depression is difficult for both patients and for psychiatrists. While there are numerous drugs available that work, finding the right one -- or right combination -- is, at times, a matter of trial and error.

Insulin receptor stops progression of Alzheimer's disease

Stimulation of a receptor in the brain that controls insulin responses has been shown to halt or diminish the neurodegeneration of Alzheimer's disease, providing evidence that the disease can be treated in its early stages, according to a study by researchers at Rhode Island Hospital and Brown Medical School.

Reactive oxygen species in cancer cells

A biochemical alteration that has long been viewed as an adverse aspect of tumor biology may turn out to be a deadly double-edged sword for the cancer cells themselves.

Discovery of a new gene that stimulates the growth of natural bypasses

World Congress of Cardiology Report - Researchers from the Max-Planck-Institute for Heart and Lung Research (MPI) in Bad Nauheim, Germany, have identified a gene, whose therapeutic use may be beneficial for patients suffering from obstructive arterial diseases.

The heart can heal itself

World Congress of Cardiology Report - Despite the dramatic advances in the care of patients with cardiovascular diseases that have occurred in the second half of the 20th century, heart failure (HF) is the most common cause of death in developed nations.

Mature muscle fibers can revert to become cancerous

Mature muscle fibers, rather than their less-developed neighbors, are the tissues that turn malignant in a soft-tissue cancer that strikes children and teens, researchers at UT Southwestern Medical Center and Children's Medical Center Dallas have found.

The endocannabinoid system controls key epileptogenic circuits in the hippocampus

The same brain machinery that responds to the active substance in marijuana provides a central "on-demand" protection against seizures, researchers have found. They said their discoveries suggest that the "endocannabinoid" system might constitute a prime target for drugs against seizures of epilepsy and other neurodegenerative diseases.

Altering fatty acid levels in diet may reduce prostate cancer growth rate

UCLA researchers found that altering the fatty acid ratio found in the typical Western diet to include more omega-3 fatty acids and decrease the amount of omega-6 fatty acids may reduce prostate cancer tumor growth rates and PSA levels.
