Friday, October 24, 2008, 07:00 PM: Life Extension with Jerry Emanuelson
Jerry will be talking about his 25+ year experience with life extension treatments, including hormone injections, his longevity doctor, what treatments to ask a doctor for, how to find and guide a doctor, an interesting example of the 'medical priesthood vs. empowered patient' conflict as more healthcare treatments are about prevention/enhancement, getting his DNA scanned with deCODEme and opensourcing his genome on the SNPedia.com, and more.

Stress

The fat on your belly may be there because of stress in your everyday life, and researchers think they may know how to get rid of it.
Studies of mice and monkeys show that repeated stress — and a high-fat, high-sugar diet — release a hormone, neuropeptide Y, that causes a buildup of abdominal fat.

A burn is not only an injury on the outside: it also involves great mental stress, which impacts healing.
Even though few people suffer burns in Sweden, about 16 per 10,000 inhabitants, burn treatment occupies a unique position in health care. First, a major burn is one of the worst injuries a person can suffer and still survive. Second, burns require long, difficult, and expensive treatment.
"We found that not only the size of the injury, but also the patient’s personality and how the individual copes with the event can affect the occurrence of itching and nightmares after the injury."
The occurrence of frequent nightmares often was clearly related to chronic stress, which means that the occurrence of nightmares can be used as a so-called screening question for stress following injury.

Chronic psychological stress is associated with accelerated shortening of the caps, called telomeres, on the ends of chromosomes in white blood cells -- and thus hasten their demise. Telomeres promote chromosome stability, Dr. Elissa S. Epel at the University of California, San Francisco, and her colleagues explain. Telomeres shorten with each replication of the cell, and cells cease dividing when telomeres shorten sufficiently.

New results challenge the view that a good night's sleep can leave behind a dense bloom of brain cells in the morning. Prior studies had found that sleep-deprived rodents grow fewer new neurons than well-rested animals, suggesting that sleep somehow promotes the birth of brain cells, called neurogenesis. But that might not be the case: researchers report instead that lack of sleep likely cuts into neurogenesis by triggering a harmful stress response.
