1 Calorie Restriction Slows Aging and Illness

Carefully calculated calorie restriction is a way of life for some people who believe it can slow the aging process and offset certain cancers. Now, research from the U of Gothenburg has identified an enzyme that is key to the aging process - and supports the theory behind limiting calorie intake. "We are able to show that caloric restriction slows down aging by preventing an enzyme, peroxiredoxin (Prx1), from being inactivated. This enzyme is also extremely important in counteracting damage to our genetic material," says researcher Mikael Molin. Previous research had shown the health benefits of reducing sugar and proteins while maintaining vitamins and minerals. Calorie restriction slows aging by increasing production of Srx1, an enzyme that repairs Prx1.

A Gentler Technique

2 Age Not a Factor in Stem Cell Transplants

A study involving 372 patients aged 60 to 75 year olds with blood cancer found that age was not a factor in determining whether or not they should have stem cell transplantation. The technique, called the "mini-transplant" was developed at the Fred Hutchinson Cancer Research Center that uses low-dose radiation and chemotherapy so the patient’s immune system kills the cancer cells before the transplant which is easier on people over 60 than the usual levels. Patients with a less aggressive type of cancer had a 69 percent five-year survival rate compared to 23 percent in individuals with a more aggressive form. Having other health problems also played a role in survival rate but age was not which was shown by comparable survival rates between 60 to 64, 65 to 69, and 70 to 75 year olds.
