Cancer-resistant mouse discovered
November 27, 2007 08:55 AM - University of Kentucky

A mouse resistant to cancer, even highly-aggressive types, has been created by researchers at the University of Kentucky. The breakthrough stems from a discovery by UK College of Medicine professor of radiation medicine Vivek Rangnekar and a team of researchers who found a tumor-suppressor gene called "Par-4" in the prostate.

The researchers discovered that the Par-4 gene kills cancer cells, but not normal cells. There are very few molecules that specifically fight against cancer cells, giving it a potentially therapeutic application.

High glycemic index diet may boost diabetes risk
November 27, 2007 08:30 AM - Reuters

NEW YORK (Reuters Health) - Regular consumption of foods with a high glycemic index appears to increase the risk of type 2 diabetes in African-American and Chinese women, according to the results of two studies published Monday.

Glycemic index refers to how rapidly a food causes blood sugar to rise. High-glycemic index foods, like white bread and potatoes, tend to spur a quick surge in blood sugar, while low-glycemic index foods, such as lentils, soybeans, yogurt and many high-fiber grains, create a more gradual increase in blood sugar.

CHICAGO (Reuters) - Pregnant women are receiving more high-tech imaging exams, exposing their babies to higher doses of radiation than a decade ago, a study said on Tuesday.

While the levels of radiation exposure are low, they carry a slight risk of harm to the developing fetus, said study author Elizabeth Lazarus, a professor of diagnostic imaging at the Warren Alpert School of Medicine at Brown University in Providence, Rhode Island.

BRUSSELS (Reuters) - Agricultural powerhouses France and Germany sought on Monday to break the deadlock that has kept genetically modified crops out of most of Europe, saying rules must be changed to ease their approval.

"This authorization process of GMOs is highly unsatisfactory and worrying, it cannot stay like this," German Agriculture Minister Horst Seehofer told reporters on arriving for a meeting of EU farm ministers.

Transcranial magnetic stimulation effective in treating major depression

PHILADELPHIA – Researchers at the University of Pennsylvania School of Medicine and other study sites have found that transcranial magnetic stimulation (TMS) – a non-invasive technique that excites neurons in the brain via magnetic pulses passed through the scalp – is a safe and effective, non-drug treatment with minimal side effects for patients with major depression who have tried other treatment options without benefit.

GE says CT scan has clearer images, cuts radiation
November 26, 2007 03:10 AM - Reuters

CHICAGO (Reuters) - A new high-definition CT scanner from GE Healthcare is producing clearer images of the body's internal organs, bones and soft tissue while reducing potentially cancer-causing radiation exposure compared with older machines, the company said on Monday.

GE Healthcare, a $17 billion unit of General Electric Co, said its new high-definition CT scanner is under U.S. regulatory review and it hopes to launch the product sometime in 2008.

GE Healthcare is showcasing the new technology at the annual meeting of Radiological Society of North America here this week.
