Discovered a new virus, provokes cancer

Scientists have found another virus, provokes cancer - one of the types of retroviruses can cause prostate cancer, which kills about 10% of men, to identify the author of an article published in the journal Proceedings of the National Ac

The Nobel Prize in medicine for 2008 was awarded for the discovery of the role of human papillomavirus in cervical cancer development. The opening of communication between the virus and the tumor has paved the way for successful treatment - enough vaccine for the virus to 95% to provide protection against cancer. This is reported by RIA Novosti.

A new study by a group of scientists from Columbia University in New York and the University of Utah, found a link between the murine leukemia virus ksenotropnym (xenotropic murine leukemia virus-related virus - XMRV) and prostate cancer.
"Our findings provide evidence of communication XMRV with malignant tumor cells," - says the article.

Ila Singh and her colleagues surveyed more than 300 samples of cancerous tissue and found in more than a quarter of the samples virus XMRV. The virus is more likely to be detected in cases of aggressive tumors, and that the viral proteins occur in cancer cells.

Virus XMRV, according to genetic data, which refers to the type of gamma-retroviruses. This type of viruses cause leukemia, sarcoma, and in many animal species, but hitherto not been known to cause cancer in humans.

Menthol cigarettes quickly addictive

The cooling flavor menthol cigarettes causes faster drug addiction

U.S. doctors have found the body of smokers prefer menthol cigarettes with additives, and gets more nicotine and carbon monoxide.

Even if a person smokes fewer cigarettes per day, menthol contributes to the development thrust to "nicotine stick" because of what was expected of such a tobacco product is twice more difficult to refuse.

Clean air affects the length of life - scientists

Reducing air pollution has contributed to an average of five months of life expectancy of people in dozens of American cities over the past two decades

Researchers from Brigham Young University and Harvard University (USA) came to this conclusion based on data from the change in air quality and life expectancy for the period from 1980 to 2000 in 51 American city, including Washington.



Taking into account the impact on life expectancy of other factors such as population changes, income and education, as well as migration and smoking, they concluded that clean air contributes significantly to increased life expectancy.



The researchers concluded that, overall, the country life of citizens has increased from 1980 to 2000 an average of 2.72 years and five months of this period due to improved air quality, transmit medicinews.ru.

Our investments are paying off," - said the study's lead author Arden Pope, an epidemiologist and professor of economics at Brigham Young University. He added that the reduction of pollution in large cities has become "a major, national, natural experiment."
