Swiss researchers found that women who have transplanted kidney men, significantly increased the likelihood of transplant rejection. In its publication in the journal "The Lancet" scientists advised to use donor organs for transplant the same sex with patients.

Researchers from the University Hospital in Basel analyzed the outcomes 195 516 transplantations carried out from 1985 to 2004 in more than 400 European hospitals. It turned out that the most common reaction transplant rejection occurs when a woman male kidney transplant - 11% more average level during the first year, and by 8% - during the entire period of observation.

This is not the first evidence of the significance of sex donor and patient. Thus, when introducing female stem cells for men increased risk of reaction "against the owner of the transplant", but with the introduction of men's women - the risk of rejection transplanted cells.

The expert Connie Davis (Connie Davis) from the University of Washington in Seattle, the accumulated facts do not allow continue to ignore the reaction of the immune system to the transplant recipient from a donor of the opposite sex.

At the same time, the representative of British service Transplantology UK Transplant said that a similar study conducted in Britain, did not reveal the influence of gender on the outcome of transplants organs, therefore grounds for recruiting the "same" no transplant.

U.S. scientists discovered the mechanism "masking" simple herpes virus in the latent stage of the disease. This opens the way for a fundamentally new drugs to treat gerpeticheskoy infection.

It is known that herpes virus is in the nerve cells infected person constantly, but clinically disease manifests itself only in the aggravation of the period, ie active breeding causative agent. The rest of the time - latent period - viral genome does not play, viral proteins on its matrix is not synthesized, there are no manifestations of the disease, but the virus is resistant to any therapy. The only molecular product of the virus in that period - RNA transcript latent stage (latency associated transcript RNA, LAT RNA), whose function until now was unknown.

Exploring the functioning of herpes virus in the latent phase of the disease in mice, researchers from Duke University in North Carolina found that LAT RNA rapidly disintegrates into smaller nucleotides, named mikroRNK. They blocked the formulation of protein, activates the virus reproduction. Periods of aggravation occur when under the action of stress factors (such as hypothermia) on the human body-bearer virus begins to produce more information RNA than mikroRNK can block, and protein synthesis is resumed.

Currently, a team of researchers conducting tests of a new drug, binding mikroRNK to translate the virus in an active state when it may be cured antiviral drugs, such as aciclovir.
