Cancer Cures. Partial reversal of aging achieved in mice. Harvard scientists at Dana-Farber Cancer Institute say they have for the first time partially reversed age-related degeneration in mice, resulting in new growth of the brain and testes, improved fertility, and the return of a lost cognitive function.
In a report posted online by the journal Nature in advance of print publication, researchers led by Ronald A. DePinho, a Harvard Medical School (HMS) professor of genetics, said they achieved the milestone in aging science by engineering mice with a controllable telomerase gene. The telomerase enzyme maintains the protective caps called telomeres that shield the ends of chromosomes. As humans age, low levels of telomerase are associated with progressive erosion of telomeres, which may then contribute to tissue degeneration and functional decline in the elderly. By creating mice with a telomerase switch, the researchers were able to generate prematurely aged mice. Importantly, the animals showed no signs of developing cancer.

Medicinal Herbs. Rapamycin, >99%, 200mg-5g (Sirolimus) - BIOTANG Inc. Rapamycin, also known as sirolimus, is especially useful in kidney transplants.
It prevents activation of T cells and B-cells by inhibiting their response to interleukin-2 (IL-2). Unlike the similarly named tacrolimus, sirolimus is not a calcineurin inhibitor, but it has a similar suppressive effect on the immune system. Sirolimus inhibits the response to interleukin-2 (IL-2), and thereby blocks activation of T- and B-cells. In contrast, tacrolimus inhibits the secretion of IL-2. The mode of action of sirolimus is to bind the cytosolic protein FK-binding protein 12 (FKBP12) in a manner similar to tacrolimus. References: Which Naturals Are Backed By Serious Science? - Health. Elixir of life discovered on Easter Island. Proof the FDA is suppressing the cure for cancer After 10 Years' Work, Scientists Unveil Detailed 3-D Map of Virus That Causes the Common Cold.
After more than a decade of work, scientists have completed a 3-D atomic-scale map of a virus that causes the common cold.
It's the largest virus ever mapped. The map could help scientists re-engineer the virus for gene therapy, as well as to create possible treatments for cancer and other ailments. Robotic systems, an advanced x-ray, and years of patience made it possible. The human adenovirus family, which is responsible for a host of ailments ranging from colds to gastrointestinal disorders, is quite good at making us sick because adenoviruses can infect many types of cells. For several years, scientists have tried to use adenoviruses as a vector to carry therapeutic genes into cells, mostly for treating cancer and cardiovascular disease.
It's not the first virus to have its structure mapped with x-ray crystallography; scientists have been doing that for some time now. The adenovirus presented a problem, however. Emotional Freedom Techniques (EFT) : How to Practice Emotional Freedom Techniques (EFT)
