If you think the air outside is polluted, a new research report in the September 2009 issue of the journal Genetics might make you to think twice about the air inside our bodies too. That's because researchers show how about 3 percent of the air we breathe gets converted into harmful superoxides, which ultimately harm our muscles.

Gene identified in age-related hearing loss

Presbycusis, or age-related hearing loss, accounts for 30 percent of all hearing loss. So, why do some people lose their hearing as they get older but other people can still hear a pin drop?

Preventing age-related brain changes in older adults

Older adults who exercise regularly show increased cerebral blood flow and a greater number of small blood vessels in the brain, according to findings presented today at the annual meeting of the Radiological Society of North America (RSNA).

Insulin-Like Proteins Linked to Age-Related Bone Loss

A recent study conducted at Mayo Clinic suggests that high levels of one of the natural insulin-like proteins involved in regulating tissue growth and maintenance in the body, Insulin-Like Growth Factor Binding Protein-2 (IGFBP-2), also may be an indicator of low bone density and high rates of bone loss in older women and men.

New strategy for protecting aging Americans against infectious disease

Researchers at Oregon Health & Science University have uncovered new information about the body’s immune system in a study that suggests new strategies may be in order for protecting the country’s aging population against disease. The research is published in the current edition of the Proceedings of the National Academy of Science.

Fighting diseases of aging by wasting energy

By making the skeletal muscles of mice use energy less efficiently, researchers report in the December issue of Cell Metabolism, a publication of Cell Press, that they have delayed the animals’ deaths and their development of age-related diseases, including vascular disease, obesity, and one form of cancer.

Age-related macular degeneration could pave way for better treatment

harminka — Wed, 10 Oct 2007 13:35:54 -0500

Researchers at the University of Pennsylvania School of Medicine have created the first animal model of age-related macular degeneration (AMD) caused by a mutation known to produce disease in people, an important first step in developing treatments. The study appears in the October issue of Human Molecular Genetics.

Inflammatory marker linked to increased risk of age-related eye disease

harminka — Tue, 09 Oct 2007 07:16:51 -0500

High blood levels of C-reactive protein, a substance linked to inflammation, appear to be associated with an increased risk for age-related macular degeneration, according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Cell death in sparrow brains to provide clues in age-related diseases

harminka — Tue, 18 Sep 2007 06:14:08 -0500

A remarkable change takes place in the brains of tiny songbirds every year, and some day the mechanism controlling that change may help researchers develop treatments for age-related degenerative diseases of the brain such as Parkinson’s and dementia.

Zeaxanthin associated with reduced risk for age-related eye disease

Consuming higher levels of the yellow plant pigments lutein and zeaxanthin may be associated with a lower risk for age-related macular degeneration, according to a report in the September issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Novel approach to uncover genetic components of aging

People who live to 100 or more are known to have just as many—and sometimes even more—harmful gene variants compared with younger people.

Loneliness is bad for your health

Two University of Chicago psychologists, Louise Hawkley and John Cacioppo, have been trying to disentangle social isolation, loneliness, and the physical deterioration and diseases of aging, right down to the cellular level.
