Study Identifies A Key Molecular Switch For Telomere Extension By Telomerase

Researchers at the University of Illinois at Chicago College of Medicine describe for the first time a key target of DNA damage checkpoint enzymes that must be chemically modified to enable stable maintenance of chromosome ends by telomerase, an enzyme thought to play a key role in cancer and aging.

Their findings are reported online in Nature Structural and Molecular Biology.

Telomeres are the natural ends of chromosomes, consisting of specialized DNA-and-protein structures that protect chromosome ends and ensure faithful duplication of chromosomes in actively dividing cells. An essential player in telomere maintenance is an enzyme complex called telomerase. Without telomerase, telomeres become progressively shorter each time the cell divides.

Revision Of Federal Nursing Home Quality Reporting System: Nursing Home Quality Scorecards Don't Tell The Whole Story

The scoring system government agencies use to rate nursing home quality does not provide an adequate evaluation because they do not take into account the degree of cognitive impairment of their patient populations and whether facilities include a specialized dementia unit according to a new study.

Focusing on statistics from Minnesota, researchers from Indiana University School of Medicine and the Regenstrief Institute report on the inadequacy of quality of care indicators for nursing home residents with behavioral and psychological systems related to dementia in a study published in the November 2011 issue of the Journal of the American Medical Directors Association.

Sex A Significant Predictor Of Happiness Among Married Seniors

elder coupleThe more often older married individuals engage in sexual activity, the more likely they are to be happy with both their lives and marriages, according to new research presented in Boston at The Gerontological Society of America's (GSA) 64th Annual Scientific Meeting.

This finding is based on the 2004 General Social Surveys, a public opinion poll conducted on a nationally representative sample of non-institutionalized English and Spanish-speaking person 18 years of age or older living in the U.S. The data analysis was conducted by Adrienne Jackson, PT, PhD, MPA, an assistant professor at Florida Agricultural and Mechanical University.
