Sanitizers better than handwashing

Hand sanitizers containing ethanol have been proven to work better against the common cold than washing hands with soap and water in a new study.

Researchers from the University of Virginia School of Medicine, Charlottesville and Dial Corporation, Scottsdale, Arizona found sanitizers containing both ethanol and organic acids were significantly more effective in removing rhinovirus, the known cause of approximately 30 to 35 per cent of common cold cases in adults.
Investigators R B Turner, J L Fuls, and N D Rodgers found the ethanol hand sanitizer removed approximately 80 per cent of detectable rhinovirus from hands while soap and water removed 31 per cent.

The researchers said: “The ethanol-containing hand disinfectants were significantly more effective than hand washing with water or with soap and water for removal of detectable rhinovirus for the hands in this study”.

“Furthermore, a formula containing organic acids and ethanol resulted in residual activity that significantly reduced virus recovery from the hands and rhinovirus infection for up to 4 hours after application.”

Turmeric may delay liver damage and cirrhosis
Adding a pinch of turmeric in your meal can delay the liver damage that eventually causes cirrhosis, says a new research.

The researchers found that curcumin, one of the principal components of the Indian spice turmeric, seems to delay the liver damage that eventually causes cirrhosis.

Curcumin, which gives turmeric its bright yellow pigment, has long been used in Indian Ayurvedic medicine to treat a wide range of gastrointestinal disorders.

It was earlier shown that it has anti-inflammatory and antioxidant properties, which may be helpful in combating disease.

The research team wanted to find out if curcumin could delay the damage caused by progressive inflammatory conditions of the liver, including primary sclerosing cholangitis and primary biliary cirrhosis.

Both the conditions, which can be sparked by genetic faults or autoimmune disease, cause the liver’s plumbing system of bile ducts to become inflamed, scarred, and blocked.
This leads to extensive tissue damage and irreversible and ultimately fatal liver cirrhosis.
The authors point out that current treatment for inflammatory liver disease involves ursodeoxycholic acid, but its long term effects remain unclear.

The other alternative is a liver transplant.
They said that curcumin is a natural product, which seems to target several different parts of the inflammatory process, and as such, may therefore offer a very promising treatment in the future.

High dietary phosphate may up skin cancer risk
A new study by researchers at Emory University School of Medicine has shown that a high intake of phosphates can contribute to tumour growth in skin cancer.

The researchers applied dimethylbenzanthracene, a carcinogen found in cigarette smoke, to the skins of mice, followed by another chemical that stimulates cell growth.

Feeding these mice a high phosphate diet (1.2 per cent by weight) increased skin papilloma number by 50 per cent compared with a low phosphate diet (0.2 per cent).
Skin papillomas are the initial stage of skin cancer development, which may progress to full carcinoma.

“This is a very well established model for the initiation and progression of cancer, and the effects of many physiological conditions on cancer initiation have been measured this way,” said senior author George Beck, assistant professor of medicine (endocrinology) and a member of the Winship Cancer Institute, Emory University.
