Two critical characteristics of breast cancer that are important to treatment can be identified by measuring gene expression in the tumor, a research team led by scientists at the University of Texas M. D. Anderson Cancer Center reports in Lancet Oncology online.
In a finding that could have profound implications for AIDS vaccine design, researchers led by a team at the NIAID have generated an atomic-level picture of a key portion of an HIV surface protein as it looks when bound to an infection-fighting antibody. Unlike much of the constantly mutating virus, this protein component is stable and — more importantly, say the researchers — appears vulnerable to attack from this specific antibody, known as b12, that can broadly neutralize HIV.
Sleep disturbances common in older people can lead to an increased risk of falling during waking hours, according to research published in the latest issue of The Journal of Gerontology: Medical Sciences (Vol. 62A, No. 1). In a special section devoted to sleep disorders, this edition of the journal features four separate reports on the topic.
Johns Hopkins cardiologists are calling for an expansion of the criteria widely used by physicians to detect and assess a postmenopausal woman’s chances of developing cardiovascular disease, the leading cause of death among women in the United States.
UM entomologist Jerry Bromenshenk and his team at Bee Alert Technologies Inc. has been enlisted to find out what’s bugging the bees –the leading pollinator of humanity’s crops. A mysterious ailment called Colony Collapse Disorder is causing agricultural honeybees nationwide to abandon their hives and disappear.
Led by researchers at Weill Cornell Medical College in New York City, an international group of scientists has pinpointed a specific genetic relationship as the cause of dangerous iron overload in persons with a form of the inherited blood disease, beta-thalassemia.
Scientific breakthrough: What caused the extinction of the woolly rhinoceros ten thousand years ago from an area in Europe covering the coasts of the Arctic Ocean in the north to the coasts of the Mediterranean in the south?
Obesity and its many related health hazards have become a serious and growing problem worldwide. While environmental and lifestyle factors play a key role in the development of obesity, genetic variation may determine an individual’s susceptibility to weight gain and to the rise of obesity-related health risks.
The entire Latin America region needs to take preventive measures to prepare for what promises to be a ?difficult year? for dengue fever following an outbreak of the mosquito-borne infection in Paraguay, United Nations health officials have warned.
University of Iowa researchers have learned more about a genetic variation that is a small risk factor for a mild form of schizophrenia yet also is associated with improved overall survival.
