'Pinball protons' created by ultraviolet rays and other causes can lead to DNA damage

Researchers have known for years that damaged DNA can lead to human diseases such as cancer, but how damage occurs--and what causes it--has remained less clear. Now, computational chemists at the University of Georgia have discovered for the first time that when a proton is knocked off one of the pairs of bases that make up DNA, a chain of damage begins that causes "lesions" in the DNA. T...

Inactivation of Contaminating Templates in PCR Using High Intensity Ultraviolet Light

Amplification of DNA through the polymerase chain reaction (PCR) is a highly sensitive method capable of copying millions of DNA molecules from just a single molecule. Because of the extreme sensitivity of this method, any carry-over product from previous reactions can result in false positiv...

Reducing TB With Ultraviolet Light

TB is a potentially fatal disease caused by bacteria. It can attack any part of the body but usually targets the lungs.// Researchers say beginning in the 1940s with the discovery of antiviral drugs, the disease slowly started to disappear in the United States. However, it began to reappear in the 1980s when the HIV epidemic surfaced. Researchers say TB is a co-infection of HIV.However, the inci...

Skin Cancer Risk Increases With Ultraviolet-B Radiation Exposure

A new study published in the December 21 issue of the Journal of the National Cancer Institute says that exposure to ultraviolet B (UV-B) radiation reduces the ability // to repair the chromosomal damage caused to the skin and hence increases the risk of developing basal cell carcinoma and squamous cell carcinoma. UV radiation is the commonest cause of skin cancer and is responsible for...

Ultraviolet B (UVB) Radiation Reduces Risk of 16 Types of Cancer in U.S.

A study published this week in Anticancer Research confirms that solar UVB irradiance is associated with reduced risk of 16 sites of cancer, apparently through production// of vitamin D. These cancers include 6 sites of gastrointestinal cancers, 3 cancers of female sites, 3 urogenital cancers, 2 types of lymphomas, and 2 upper aerodigestive tract cancers. The analysis examined age-adj...

Suntan Helps to Prevent the Cancerous Effects of Ultraviolet Rays

A recent research has found that a suntan is the bodys best effort to deflect the known cancerous effects of ultraviolet (UV) light .Researchers at the Harvard-affiliated Dana Farber Cancer Institute in Boston have conducted a series of experiments and found that a suntan helps prevent the body from the cancerous effects of ultraviolet rays.However, they maintain that this finding sho...
