Long-term use of NSAIDs cuts the risk for oral cancer in smokers by half but increases risk of cardiovascular problems

An analysis of 20 years of data on the health of over 900 adults has found that long-term use of traditional nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, cuts the risk for oral cancer in smokers by half.

Minimally invasive needle breast biopsies and sentinel node biopsies should be performed more routinely than they currently are

Physicians should strive to replace traditional, invasive procedures for diagnosing breast cancer with proven, less-invasive diagnostic methods, according to an international panel of breast cancer experts convened at the Keck School of Medicine of the University of Southern California.

New role for the blood protein serum amyloid P in the body's response to medical materials

Using a technique called proteomics, the researchers identified many of the blood proteins that stick (adsorb) to the surfaces of medical devices. Blood proteins that adsorb to the surfaces of materials unfold and can be recognized by the body, which then mounts a response against the device.

Deadly 1918 Spanish flue virus has been reconstructed and characterized

This research, reported in this week's issue of Science, is part of a larger research initiative being led by Adolfo Garcia-Sastre, PhD, Professor of Microbiology and Peter Palese, PhD, Professor and Chairman of Microbiology at Mount Sinai School of Medicine.

Cost-effectiveness of potentially life-saving implantable cardioverter defibrillators (ICD) is an important public health issue

The use of implanted defibrillators that keep the heart beating in proper electrical rhythm to prevent cardiac arrest appears to be cost-effective for those patients who receive a significant mortality reduction, according to researchers from Duke Clinical Research Institute (DCRI), Stanford University and the VA Palo Alto Health Care System, Calif. They analyzed eight clinical trials of the devices to arrive at their conclusion.

Students with higher levels of emotional intelligence achieve more academically

The emotional intelligence of students indirectly contributes to academic success in information technology studies, preliminary results from a study led by Virginia Tech researchers show.

Mechanism of X-chromosome dosage compensation in Drosophila

In Drosophila, like in humans, male cells have a single X chromosome, while female cells have two. Researchers have long debated over how X and autosomal chromosome gene expression is equalized between the sexes (generally regarding two different models, known as the activation model and the inverse model).

Largest systematic analysis of duplicated gene function to date

When Mother Nature creates an identical copy of a gene in an organism's genome, the duplicated copy is usually deleted, inactivated, or otherwise rendered nonfunctional in order to prevent genetic redundancy and to preserve biological homeostasis. In some cases, however, gene duplicates are maintained in a functional state.

Beta glucan may help treat skin disorders and remove fine lines and wrinkles

The fight against aging has received a scientific boost thanks to an innovative study done in part by a University of Alberta spin-off company--research that dispels a hard-held belief about the natural ingredient, beta glucan.

Cost-effective technique for reducing mercury emissions from coal-fired power plants

Researchers at Lehigh University's Energy Research Center (ERC) have developed and successfully tested a cost-effective technique for reducing mercury emissions from coal-fired power plants.

First direct clues about how the brain alters the state of consciousness during sleep

In the human brain, cells talk to one another through the routine exchange of electrical signals. But when people fall into a deep sleep, the higher regions of the brain - regions that during waking hours are a bustling grid of neural dialogue - apparently lose their ability to communicate effectively, causing consciousness to fade.

Healthy 3 and 4-year-olds drive flu epidemics

Current immunization policies recommend universal flu vaccination for children aged 6-23 months, but shots are advised for older children only if they have high-risk medical conditions.

Organosilicon compounds help improve lithium battery technology

With the help of new silicon-based compounds, scientists -- and patients -- are getting a significant new charge out of the tiny lithium batteries used in implantable devices to help treat nervous system and other disorders.

Microarray technology may help tailor breast cancer therapy

Microarray technology could be used to tailor therapy according to the individual, and prevent breast cancer patients from having to undergo painful unsuccessful therapies.

MRI may better enable physicians to plan care for infants with heart defects

Magnetic resonance imaging (MRI) techniques can provide real-time measurements of volume in a fetal heart, and may better enable physicians to plan care for infants with heart defects, according to a new study.

Grant for private, secure, electronic medical records search system

A Boston consortium has been awarded one of two national grants to form a CDC Center of Excellence in Public Health Informatics.

HeartMate XVE left ventricular assist device

Nine years ago this week, a team of University of Michigan doctors gave a dying heart patient a second chance at life by implanting a high-tech pump in his chest. The high-risk procedure was the first in Michigan performed using a new blood-pumping device called a HeartMate XVE left ventricular assist device, which helped the patient live until he received a heart transplant five weeks later.
