Genetic testing can be used to distinguish between ischemic and nonischemic forms of heart failure

Researchers at Johns Hopkins have shown that genetic testing can be effectively used to distinguish between heart failure patients who suffer from ischemic or nonischemic forms of the disease.

Sexual competition among males is evident at the molecular level, as well as at behavioral and physiological levels

In what could be termed a truly seminal discovery, researchers have shown that when females are more promiscuous, males have to work harder -- at the genetic level, that is. More specifically, they determined that a protein controlling semen viscosity evolves more rapidly in primate species with promiscuous females than in monogamous species.

Researchers find two locations in the human genome that may harbor genes that increase the risk of Alzheimer’s disease

Researchers at Columbia University Medical Center have found two locations in the human genome that may harbor genes that increase the risk of Alzheimer’s disease. If confirmed, they will be the first genes linked to Alzheimer’s disease since ApoE4 was discovered in 1993.

Autophagy may even provide a clue to the mythical fountain of youth

The cells of higher organisms have an internal mechanism for chewing up and recycling parts of themselves, particularly in times of stress, like starvation and disease. But nobody is quite sure yet whether this recently discovered process protects cells, or causes damage.

alpha4 may prove to be useful target for smoking addiction therapies

Nicotine is responsible for more than four million smoking-related deaths each year. Yet people still smoke. Why? One reason is the stranglehold of addiction, started when nicotine enhances the release of a neurotransmitter called dopamine

Cellular vehicle delivers drugs directly into cancer cells

Researchers at The University of Texas M. D. Anderson Cancer Center have perfected a delivery system for anticancer treatment that zeroes in on a tumor and becomes part of its supporting tissue.

Discovery of internal molecular clock that governs the metabolism of sugars and fats within the body

Researchers at the University of Pennsylvania School of Medicine have discovered that components of the internal molecular clock of mammals have an important role in governing the metabolism of sugars and fats within the body.

Sensor protein that identifies DNA breaks and activates the p53 cell-death program has been identified

DNA breaks from radiation, toxic chemicals, or other environmental causes occur routinely in cells and, unless promptly and properly repaired, can lead to cancer-causing mutations.

Sperm cells grown in laboratory culture

A team of researchers working with cells from mice has overcome a technical barrier and succeeded in growing sperm progenitor cells in laboratory culture.

Gene mutations responsible for causing cataracts in children, identified

Gene mutations responsible for causing cataracts in children have been identified by a team of University of Utah vision researchers. The discovery was reported in a recent issue of The Journal of Medical Genetics.

Genetic mutations could collectively raise bowel cancer risk

Cancer Research UK scientists at the University of Oxford have found that a number of genetic mutations could collectively raise bowel cancer risk, reporting their findings in the journal PNAS.

Discovery of a new blindness gene

The discovery by a Leeds University scientist of a new blindness gene could help to save the sight of thousands of sufferers of retinal disease which affects premature babies as well as people over 60.

Scientists have identified the gene which produces the hereditary Park8 variant of Parkinson’s

Research began when doctors discovered that various members of the same family had Parkinson’s. There are many kinds of Parkinson’s and some are hereditary.

Gene regulated by need to process proteins linked to enlargement of protein processing factory

Part of a cellular mechanism that regulates the folding of new proteins into their proper shapes also includes a genetic response that enlarges the factory where both protein folding and packaging of proteins occurs.

Possible treatment for the fatal lung disease idiopathic pulmonary fibrosis

They found that the anti-cancer drug imatinib mesylate — commercially known as Gleevec and produced by Novartis Pharmaceuticals — can target a gene critical to controlling the disease process. Previously, there had been no treatment and patients usually did not survive beyond three years of diagnosis. Now the treatment is undergoing clinical trials at Mayo Clinic.

Genetic link suggested in deaths from cardiac valve diseases

Deaths from cardiac valve diseases appear to run in families, suggesting a significant genetic component, according to a study published in Circulation: Journal of the American Heart Association.

Study results suggest that metronidazole and clindamycin differ in their effects on microbes in women with bacterial vaginosis

In the first study to directly compare the emergence of antibiotic resistance following topical treatment between two antibiotics routinely prescribed for a common vaginal infection, researchers from the Magee-Womens Research Institute have found antibiotic-resistant bacteria more likely to develop with the drug clindamycin than metronidazole.

Diabetic or obese patients suffering advanced heart failure have higher levels of fat embedded in their hearts

Heart failure, progressive and potentially fatal weakening of the heart muscle, is associated with both obesity and diabetes, but the mechanisms by which damage occurs are not well-understood, said senior author Heinrich Taegtmeyer, M.D., Ph.D., professor of cardiology.

Protein important to nerve development serves the dual purpose of stimulating the growth of blood vessels

The discovery opens the possibility that blood vessel growth (angiogenesis) one day may be induced, or stymied, for therapeutic use against heart disease, cancer, and other illnesses, according to Dean Y. Li, M.D., Ph.D., associate professor of internal medicine in the U of U School of Medicine's Division of Cardiology.

New rapid gonorrhea test that does not require collection

Potential antimicrobial resistance in the bacteria that cause gonorrhea can be detected without culturing the organism, thanks to a rapid test developed by researchers at Johns Hopkins.
