Discovery of new gene FANCM sheds light on repair of damaged DNA

National Institute on Aging (NIA) researchers have discovered a new gene, FANCM, which sheds light on an important pathway involved in the repair of damaged DNA.

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.

Loss of a gene called p63 accelerates aging in mice

Researchers have discovered that the loss of a gene called p63 accelerates aging in mice. Similar versions of the gene are present in many organisms, including humans. Therefore, the p63 gene is likely to play a fundamental biological role in aging-related processes.

Study shows more obesity-related arthritis among baby boomers

Baby-boomers have spent more years living with more obesity than the previous generation, researchers at Beth Israel Deaconess Medical Center (BIDMC) have found. Although it may be too early to tell whether this will lead to a rise in arthritis rates, the study shows more obesity-related arthritis among baby boomers compared to the previous generation.

Decline in energy production by mitochondria appears to be a key problem leading to insulin resistance

A detectable decline in energy production by mitochondria - the organelles that are the cell's furnace for energy production - seems to be a key problem leading to insulin resistance, and thus to type 2 diabetes, according to studies by Howard Hughes Medical Institute researchers.

Key toxin could provide for world's first treatment for Alzheimer's

Dr Karen Cullen at Sydney University’s Institute for Biomedical Research is part of a collaborative team which has identified a key component in the progression of Alzheimer’s disease, a finding which may produce the world’s first effective treatment to combat the debilitating effects of the disease.

Calcium fights prostate cancer

Calcium, more familiar in its role as one of the building blocks of the body, is being enlisted as a tool in the fight against prostate cancer.

Folates best at preventing Alzheimer's disease

According to results from a long-term study on aging, adults who eat the daily recommended allowance of folates significantly reduce their risk of developing Alzheimer's disease.

Early menstruation is not by itself a risk factor for later obesity

Although overweight girls are more likely to start their periods earlier than their peers who are at or below normal weight, early menstruation is not by itself a risk factor for later obesity, according to a long-term study released this week.

Vitamin B reduces risk of developing Alzheimer's disease

Adults who eat the daily recommended allowance of folates - B-vitamin nutrients found in oranges, legumes, leafy green vegetables and folic acid supplements - significantly reduce their risk of developing Alzheimer's disease, according to results from a long-term National Institute on Aging study of diet and brain aging.

Genes interact with behavior to affect how well people move

Genes can keep elderly people from benefiting equally from exercise, no matter how much effort they expend, according to research findings published in today's (Aug. 10) Journal of the American Medical Association.

New study points to new treatments for some forms of Lou Gehrig's disease

A new study indicates that mutant Cu/Zn superoxide dismutase (SOD1) enzymes that are associated with an inherited form of Lou Gehrig's disease cause the protein to become sticky in tissues. Partial unfolding of the mutant protein can expose hydrophobic residues that may promote abnormal interactions with other proteins or membranes in the cell.

Cancer causing potential of the sex hormones

The cancer causing potential of the sex hormones used in hormone therapy has been known since the 1930s, say researchers and women's health advocates in the Journal of Epidemiology and Community Health.

Assisted living and in-home care increase as nursing home beds decline

Even with the U.S. population rapidly aging, a smaller proportion of elderly and disabled people live in nursing homes today compared to 1990. Instead, far more depend on assisted living residences or receive care in their homes, according to a study published in the August 2005 issue of the Journal of Applied Gerontology.

Airline pilots have an increased risk of nuclear cataracts

Airline pilots have an increased risk of nuclear cataracts [common type of cataract, associated with aging] compared with non-pilots, and that risk is associated with cumulative exposure to cosmic radiation, according to a study in the August issue of Archives of Ophthalmology.

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.

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.

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.
