Washington, March 6 : Researchers at the Stanford University School of Medicine have compiled a list of 93 common mutations of the AIDS virus, which are associated with drug resistance.

The researchers, who carried out this work in collaboration with the World Health Organization and seven other laboratories, say that the list can be used to track future resistance trends throughout the world.

London, Mar 6 (ANI): A cure for scurvy - disease resulting from a deficiency of Vitamin C - was discovered nearly 50 years before physician James Lind came up with a treatment.

A newly discovered handwritten book has pointed that Ebot Mitchell concocted a remedy in 1707 - some 46 years before Lind realised vitamin C could cure the condition.

According to the newly discovered tome, the disease which was the scourge of sailors for centuries could be cured with the help of extracts from various plants mixed with a plentiful supply of orange juice, white wine or beer.

Had the remedy been known earlier in the 18th century, it could have saved thousands of lives, reports The Telegraph.

Washington, Mar 6: A research team led by an Indian origin scientist has shed light on how stem cells turn into blood cells.

Stem cells are the building blocks of every organ and tissue in the body. They have a unique ability to become any type of cell in the body including bone, muscle and blood cells.

Dr. Mick Bhatia, director of the McMaster University Stem Cell and Cancer Research Institute claim to have identified a particular cell pathway, known as the noncanonical Wnt that prompts stem cells to specialize and become blood cells.

Washington, Mar 6 : Challenging a recent study, an Arizona nutritionist has claimed that vitamin C does not reduce the effectiveness of chemotherapeutic drugs in cancer treatment.

A study published in Cancer Research concluded that vitamin C, given to mice or cultured cells treated with common anti-cancer drugs, reduces the anti-tumour effects of the chemotherapeutic agents.

Jack Challem, a personal nutrition coach and nutrition author from Tucson, Arizona, pointed out two main problems with the study.

Washington, Mar 6: Routine intake of green tea can help promote healthy teeth and gums, according to a new study.

The study analyzed the periodontal health of 940 men, and found that those who regularly drank green tea had superior periodontal health than subjects that consumed less green tea.

"It has been long speculated that green tea possesses a host of health benefits," said study author Dr. Yoshihiro Shimazaki of Kyushu University in Fukuoka, Japan.

Washington, Mar 6 : Older women exposed to high levels of family violence during lifetimes are likely to have poor health, according to a new study.

In the study involving African American women aged 50 years or older, the researchers found that exposure to family violence, be it intimate partner violence or elder maltreatment, worsens their physical and mental health.

The authors suggest that a holistic approach to caring for older women should include greater awareness by clinicians of current and past violence exposure and the negative effects it may have on the health status of these women.
