Certain gene variation associated with better mobility for older individuals who exercise

Older individuals with a certain gene variation who exercise are less likely to develop mobility limitations than individuals without the gene variation, according to a study in the August 10 issue of JAMA: The Journal of the American Medical Association.

Important breast cancer discovery

Scientists at the McGill University Health Centre (MUHC) have made an important discovery that will advance our understanding of how the female hormone estrogen causes growth of breast cancer cells. The research, in collaboration with scientists at the Institut de Recherches Cliniques de Montreal (IRCM) identifies 153 genes that respond to estrogen and one in particular that can be used to halt the growth of breast cancer cells.

Quality of the doctor-patient relationship can greatly affect patients' medication use

Patients who trust their doctors are more likely to stick to their prescription medicines, even if they face high out-of-pocket costs, a new study finds. But patients who have lower levels of trust in their physicians, or who have depression-like symptoms, are much more likely to skip doses or refills when costs become a problem for them.

Current clinical practice guidelines are not written with older adults with multiple illnesses in mind

The aging of the population and the increasing prevalence of chronic diseases pose challenges to the development and application of clinical practice guidelines (CPGs), according to background information in the article. In 1999, 48 percent of Medicare beneficiaries aged 65 years or older had at least 3 chronic medical conditions and 21 percent had 5 or more.

Biochemists reveal the first structural details of microcompartments

UCLA biochemists reveal the first structural details of a family of mysterious objects called microcompartments that seem to be present in a variety of bacteria. The discovery was published Aug. 5 in the journal Science.

Faster and more objective way to examine the surfaces of fossilized teeth

Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors.

Placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases as embryonic stem cells

Routinely discarded as medical waste, placental tissue could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cells and available now as an early online publication in Stem Cells Express.

High insulin levels increase inflammatory markers and beta-amyloids

Moderately elevated levels of insulin increase the levels of inflammatory markers and beta-amyloid in plasma and in cerebrospinal fluid, and these markers may contribute to Alzheimer's disease, according to a new study posted online today from Archives of Neurology, one of the JAMA/Archives journals.

Latest findings on aspirin resistance

Treatment failures occur with any drug and aspirin is no exception. Evidence is growing that some people will not respond to the anti-coagulant action of aspirin and the drug will not protect against cardiovascular events despite its regular intake.

Findings do not support the hypothesis of increased risk of nontargeted infectious disease hospitalization after childhood vaccination

New research does not support a belief that children receiving multiple vaccines increase their risk of hospitalization for a nontargeted infectious disease, according to a study in the August 10 issue of JAMA: The Journal of the American Medical Association.

Majority of Americans believe that vaccines are the best hope for controlling the global AIDS epidemic

But while most of those surveyed felt it personally important to help support HIV vaccine research, a majority expressed reluctance to support a friend or family member's participation in an HIV vaccine clinical trial.

Researchers look at how we understand visual images

The figure is famous: a deceptively simple line drawing that at first glance resembles a vase and, at the next, a pair of human faces in profile. When you look at this figure, your brain must rapidly decide what the various lines denote. Are they the outlines of the vase or the borders of two faces? How does your brain decide?

Non-melanoma skin cancers in young adults has increased significantly in the last three decades

"Because non-melanoma skin cancers generally occur in persons after 50, very little attention has been paid to their incidence in younger adults and children," says Leslie Christenson, M.D., Mayo Clinic dermatologist and lead investigator of the study.
