Hey guys, remember the muscle shirts we wore in our teens and 20s? After the age of 40 that meager part of our wardrobes usually is obsolete. Yes, at the big 4-0 we begin to lose muscle, and by age 80 up to a third of it may be gone. It's an inevitable process of aging called sarcopenia. Why does sarcopenia happen and can it be stopped? A study conducted in mice with accelerated muscle loss at The University of Texas Health Science Center at San Antonio provides this insight: Less protection from antioxidants and more damage from oxidative stress results in impairment to cells' energy centers, which slowly leads to death of muscle cells. A team directed by Holly Van Remmen, Ph.
Moderate or high physical activity appears to be associated with a lower the risk of developing cognitive impairment in older adults after a two-year period. Thorleif Etgen, M.D., of Technische Universit√ t M√ nchen, Munich, and Klinikum Traunstein, Germany, and colleagues examined physical activity and cognitive function in 3, 903 participants (older than 55) from southern Bavaria, Germany between 2001 and 2003. At the beginning of the study, 418 participants (10.7 percent) had cognitive impairment. After two years, 207 (5.9 percent) of the remaining 3, 485 unimpaired study participants developed cognitive impairment. "The incidence of new cognitive impairment among participants with no, moderate and high activity at baseline was 13.
National Positive Ageing Strategy: Minister Aine Brady TD Invites Older People To Have Their Say, Ireland
The Minister for Older People and Health Promotion, Aine Brady TD said that she is beginning a series of meetings around the country to hear at first hand the views of older people on issues that affect them.

"Federal healthcare benefits are going unclaimed by an estimated 17, 000 Californians whose jobs were moved overseas or retirees whose pensions are being paid by the government after their former employers terminated their retirement plans, " the Los Angeles Times reports." "So far, less than a third of those in the state who could be eligible are getting the money that can pay as much as 80% of their healthcare costs." The federal government has launched a major effort "to find people who are eligible. The Internal Revenue Service, which is in charge of finding eligible recipients, will hold a series of meetings in states with low participation, including California, Georgia and New York.

A novel finding, described Feb. 4 on the Science Express Web site by teams from the National Cancer Institute, The University of Texas Health Science Center at San Antonio and the University of Toronto, offers a clue as to how genes can have what you might call multiple personalities. Genes are long strings of DNA letters, but they can be cut and spliced to make different proteins, something like the word "Saskatchewan" can have its middle cut out to leave the word "Swan, " its front, middle and end deleted to leave the word "skate, " or its front and back chopped off to make the word "chew." Thi's discovery reveals that the protein MRG15, which previously had been known to affect cell growth and aging, also directs the gene-splicing machinery.
