Researchers find gene that is important for the control of fundamental rhythms in nematode worms

University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping.

Discovery of new features of a key quality-control mechanism in our cells

Mutations in genes are the basis of evolution, so we owe our existence to them. Most mutations are harmful, however, because they cause cells to build defective proteins. So cells have evolved quality control mechanisms that recognize and counteract genetic mistakes.

20 percent of people with chronic hepatitis C who receive a liver transplant will develop advanced cirrhosis

A new study from the University of North Carolina at Chapel Hill School of Medicine may have found a way to identify those at greatest risk, thereby allowing doctors to decide who should receive treatment that could save the transplanted organ. The new findings appear in the October issue of the journal Liver Transplantation.

Specific gene on chromosome 15 regulates inflammation

A team of international researchers has discovered that a specific gene on chromosome 15 regulates inflammation, a finding with implications for a wide range of disorders, including cancer, cardiovascular disease, diabetes, obesity, Alzheimer's, and infections. The findings are published in the October 9 online issue of Nature Genetics.

Avian influenza and the U.S

If a virulent strain of avian influenza ever struck the U.S. poultry industry, this country probably would fare better than many other nations due to careful biosecurity procedures in force.

Cells inside the hair follicle are true multipotent stem cells

Using an animal model, a research team led by Yann Barrandon at the EPFL (Ecole Polytechnique Federale de Lausanne) and the CHUV (Lausanne University Hospital) has discovered that certain cells inside the hair follicle are true multipotent stem cells, capable of developing into the many different cell types needed for hair growth and follicle replacement.

The cocktail party problem

Known as "the cocktail party problem," the ability of the brain's auditory processing centers to sort a babble of different sounds, like cocktail party chatter, into identifiable individual voices has long been a mystery.

GRK5 protein plays important role in hypertension

Researchers at Jefferson Medical College have implicated a protein called GRK5 as having an important role behind essential hypertension, which affects more than 65 million Americans.

High blood glucose levels early in pregnancy deprive the embryo of oxygen

The babies of women with diabetes are two to five times more likely to develop birth defects than offspring of women without the disease.

First recordings from medial mammillary body cells in awake animals

It's often said that the key to Bill Bradley's basketball success was summed up in the title of the 1965 book by John McPhee, "A sense of where you are." Bradley always seemed to know where all nine other players were, where Bradley himself was in relation to the basket – and where the open spot was to be found for his stylized jump shot.

Johns Hopkins awarded $12 million to study how stem cell therapies can be used to treat hearts damaged by heart attack

Heart specialists at Johns Hopkins Heart Institute have been awarded more than $12 million from the National Heart, Lung, and Blood Institute (NHLBI) to study how stem cell therapies can be used to treat hearts damaged by heart attack or heart failure.

First conference focusing on assessing and improving the organizational environment and culture of academic medical centers

Rigorous course work, state of the art laboratories, relevant textbooks and demanding clinical rotations produce technically competent physicians. But surveys say that in addition to highly qualified care givers, we want doctors who are compassionate and know how to communicate well when caring for us and our loved ones

Use of the antibiotic amoxicillin during infancy appears to be linked to tooth enamel defects in permanent teeth

Dental fluorosis, a result of exposure to excessive fluoride during enamel formation, is one of the most common developmental enamel defects, according to background information in the article.

Discovery has implications for research on restoring mobility to people who have lost motor functions due to spinal cord injury

Yale School of Medicine researchers report in Science this week genetic evidence for the hypothesis that myelination, or formation of a protective sheath around a nerve fiber, consolidates neural circuitry by suppressing plasticity in the mature brain.

Research on cartilage erosion and bone abnormalities

While characteristic of osteoarthritis (OA), a degenerative joint disease that affects some 20 million Americans, cartilage erosion and bone abnormalities are also associated with many rare hereditary conditions.

Potential biomarker that could be used to predict who might develop hepatic fibrosis

Two new studies on Hepatitis C (HCV) patients who underwent liver transplants examined a potential biomarker that could be used to predict who might develop hepatic fibrosis, a formation of scar-like tissue that can lead to cirrhosis.

Lack of oxygen in body tissues creates a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung

What's more, the team demonstrated through studies in people and animals that inhalation of a 'souped up' form of nitric oxide, which targets red blood cells, reverses the blood abnormality to restore normal lung pressure.

Compounds secreted by frog skin are potent blockers of HIV infection

The findings could lead to topical treatments for preventing HIV transmission, and they reinforce the value of preserving the Earth's biodiversity.

Potential beneficial effect of copper orotate

As one of the services for patients with Alzheimer's disease, the Department of Psychiatry at the Saarland University Medical Center offers participation in a clinical phase II trial. This clinical trial aims to elucidate a potential beneficial effect of copper orotate (an organic copper salt), which is given together with a standard cholinesterase inhibitor.
