U.S. and Japanese researchers say papaya leaf extract has had an anti-cancer effect in laboratory tests.

Dr. Nam Dang of the University of Florida and colleagues in Japan say "tea" made from the dried leaves of the papaya plant fights lab-grown tumors -- including cancers of the cervix, breast, liver, lung and pancreas.

New Study Questions Benefits of Elective Removal of Ovaries During Hysterectomy PDF Print E-mail
Wednesday, 10 March 2010 00:00
Removal of the ovaries (bilateral oophorectomy) while performing a hysterectomy is common practice to prevent the subsequent development of ovarian cancer. This prophylactic procedure is performed in 55% of all U.S. women having a hysterectomy, or approximately 300,000 times each year. An article in the March/April issue of The Journal of Minimally Invasive Gynecology suggests that this procedure may do more harm than good.
Garlic may harbour cancer cure PDF Print E-mail

In a small pilot study, the test suggested that the more garlic people consumed, the lower the levels of the potential carcinogenic process were.

The research is all about body processes associated with nitrogen-containing compounds, scientists say. These processes include nitrosation, or the conversion of some substances found in foods or contaminated water into carcinogens.

Weed killer can turn male frogs into females, study finds PDF Print E-mail
Tuesday, 02 March 2010 00:00
Researchers in the United States say they have turned male frogs into females by exposing the amphibians to tiny amounts of atrazine, a weed killer widely used on corn fields in Canada and often found in water supplies in agricultural areas.

The chemically induced sex change occurred by dosing frogs at concentrations of the herbicide 50 per cent below Health Canada's guideline for drinking water.

Long-term cannabis use can double risk of psychosis PDF Print E-mail
Monday, 01 March 2010 00:00
Young people who smoke cannabis or marijuana for six years or more are twice as likely to have psychotic episodes, hallucinations or delusions than people who have never used the drug, scientists said on Monday.

The findings adds weight to previous research which linked psychosis with the drug -- particularly in its most potent form as "skunk" -- and will feed the debate about the level of controls over its use.

Vitamin D Deficiency Likely Among Many Patients Starting Dialysis PDF Print E-mail

Vitamin D deficiency is almost universal in patients with kidney disease with low blood albumin levels who begin long-term dialysis during the winter, according to the results of a study reported in the March issue of the Clinical Journal of the American Society of Nephrology.

"This research identifies risk factors for nutritional vitamin D deficiency in the dialysis population and may provide clues to its biology in this population," lead author Ishir Bhan, MD, MPH, from Massachusetts General Hospital in Boston, said in a news release.

The hope of music's healing powers PDF Print E-mail
Monday, 01 March 2010 00:00
Yes, yes, it hath charms to soothe a savage breast (or beast, if you prefer to repeat a common mistake). But researchers are finding that music may be an effective balm for many other afflictions: the isolation of conditions such as autism and Alzheimer's disease, the disability that results from stroke, the physical stress of entering the world too early.

The hope of music's curative powers has spawned a community in the United States of some 5,000 registered music therapists, who have done post-college study in psychology and music to gain certification. Active primarily in hospitals, nursing homes, special needs classrooms and rehabilitation units, music therapists aim to soothe, stimulate and support the development or recovery of abilities lost to illness or injury.

Vitamin D Linked to Lower Heart Risk PDF Print E-mail

Vitamin D supplements may not only help your bones, they may help protect your heart.

A new review of research on vitamin D and calcium supplements shows that people who take moderate to high doses of vitamin D have a lower risk of heart disease. Calcium supplements seemed to have little effect on heart disease risk.

Vitamin D is produced by the body in response to exposure to sunlight but is also commonly found in fortified dairy products and supplements. It is already known to play a critical role in calcium absorption and bone health, but a growing number of studies suggest that vitamin D supplementation may also lower the risk of heart disease.

A vast iceberg that broke off eastern Antarctic earlier this month could disrupt marine life in the region, scientists have warned.

They say the iceberg, which is 78km long and up to 39km wide, could have consequences for the area's colonies of emperor penguins.

The emblematic birds may be forced to travel further afield to find food.

The iceberg calved from the Mertz Glacier Tongue after it was hit by another huge iceberg, called B9B.

Derivatives of resveratrol -- found in red wine grapes -- may impede cancer cell development, U.S. researchers said.

The National Cancer Institute has teamed with a biotech firm to examine the potential benefit of resveratrol among cancer patients.
