Could Spare Half of Women From Chemotherapy

Oncologists at the Duke Comprehensive Cancer Center are testing a new technique called gene expression profiling that subtypes each breast cancer tumor by its genetic defects so that doctors can tailor their treatment to inhibit that particular tumor.

The researchers believe the technique could spare millions of women from needlessly receiving toxic chemotherapy, and they are leading a national clinical trial to study gene profili

New analysis challenges results of previous research

Researchers from the Johns Hopkins Bloomberg School of Public Health, the Tyndall Centre for Climate Change Research at the University of East Anglia, the Earth Institute at Columbia University, and other institutions conclude that the increase in the incidence of malaria in East Africa parallels warming trends over the last several decades. The new findings challenge the results of a study, “Climate change and resurgence of malaria

Mental health experts at Cedars-Sinai shed light on seasonal affective disorder With the Holiday celebrations to attend and family gatherings to prepare for, the winter season can be a busy and joyful time of year. But for many, changes in light and temperature combined with the stresses of holiday events and heightened expectations can increase anxiety and cause depression. Seasonal Affective Disorder (SAD) is a mood disorder associated with depression episodes and related to seasona

A team of researchers at Virginia Commonwealth University (VCU) and the University of Pittsburgh Medical Center have linked an area of chromosome 10p to families with a history of bulimia nervosa, providing strong evidence that genes play a determining role in who is susceptible to developing the eating disorder.

The finding, gleaned from blood studies of 316 patients with bulimia and their family members, is the result of the first multinational collaborative genome-wide linkage scan to lo

Rush is first site in the Chicago area to obtain the stereotaxis technology and one of only two in the world with an emphasis on neurosurgical applications

Neurosurgeons at Rush-Presbyterian-St. Luke’s Medical Center have become the first in the Chicago area to use a radically new, magnetically controlled system to enter the brain and its vascular system to treat a variety of diseases without surgically opening up the skull and brain.

“Magnet-guided neurosurgery allows

Key step in process of developing targeted therapeutics to combat epilepsy

Scientists from Toronto’s Princess Margaret Hospital are able to depict for the first time how an important molecule called IP3 and its receptor interact to control calcium levels in cells, a process that is vital to normal brain function.

The study is published in this week’s edition of the international scientific journal Nature, and is a collaboration between scientists at Princess Margar
