Brenner Children's Hospital, part of Wake Forest University Baptist Medical Center, was recently invited to participate in the National Institutes of Health (NIH) Pediatric Heart Network. Brenner Children's Hospital will join 10 other children's hospitals in the nation conducting clinical trials on patients with heart defects.
As the dealth toll from the Dec. 26 earthquake and tsunami climbed above 200,000, a psychologist who just returned from Indonesia warned of a new danger among the survivors -- a mental health crisis.
General news and science reporters, editors, broadcasters and photographers are invited to The Johns Hopkins University School of Medicine Friday, Jan. 28, to hear six of the nation.s best-known biological scientists -- including Nobel laureates David Baltimore and Sydney Brenner -- at a symposium, "Toward the Third New Biology."
Timing is everything, it seems, even in science. A team led by Johns Hopkins scientists has unraveled the first step in translating genetic information in order to build a protein, only to find that it's not one step but two.
A new study on the determination of how livers are allocated for transplants examined the relationship between liver disease severity and quality of life, and found that the commonly used model for liver allocation is not a reliable indicator of general quality of life.
Research has found significant age differences between male and female Academy Award nominees and winners. This discrepancy may result from gender differences in actors' ages when they first begin their acting careers.
Emancipation Classical polyandry occurs when female breeds with several males who raise their offspring alone. Three evolutionary steps are crucial for this type of mating system. First, males take on care of eggs. Second, females become able to lay more eggs than a male can accommodate. Third, females compete with each other to lay clutches for several males. Successful polyandrous females have more offspring, thereby spreading characteristics that make for success in competition over males.
Researchers at the Johns Hopkins Bloomberg School of Public Health estimate that many rivers and streams in the United States contain a toxic antimicrobial chemical. Triclocarban, has been widely used for decades in hand soaps and other cleaning products, but rarely was monitored for or detected in the environment. The new findings suggest that triclocarban contamination is greatly underreported.
The Journal of Rehabilitation Research and Development (JRRD) has compiled a compendium of articles describing advances in limb loss and prosthetics research published in 2004. This research provides state-of-the-science knowledge, evidence-based rehabilitation practices, techniques, and devices that enable veterans and others with limb loss to improve their health outcomes, to participate in sports and leisure activities, and to perform the mundane activities of daily-living able-bodied people take for granted.
Major developments in biotech, genomics and stem cell research now offer exciting and far-reaching new opportunities for health care in conditions ranging from Alzheimer's and Parkinson's disease to genetic disorders. However the very pharmaceutical companies who could otherwise be expected to bring the relevant treatments to the market place are facing disturbingly turbulent conditions in their relations with policy makers, regulators and members of the public.
Older women who drink a moderate amount of alcohol each day may be helping to keep their minds sharp, according to researchers at Wake Forest University Baptist Medical Center and colleagues
University of Michigan researchers have developed a faster, more efficient way to produce a wide variety of nanoparticle drug delivery systems, using DNA molecules to bind the particles together.
A new study shows that millions of people who had little risk of gastrointestinal bleeding ended up getting prescriptions for Vioxx, Celebrex and other medicines in their class, known as COX-2 inhibitors.
Before drugs such as Vioxx and Celebrex were connected to heart attacks, there was concern that these drugs were over-used, often by patients unlikely to benefit from this type of medication. In the Archives of Internal Medicine, researchers show that most of the growth in the use of these drugs occurred in patients at little risk for side effects from the inexpensive medications that the costly COX-2 drugs were developed to replace.
To identify the best treatment for recurrent ovarian cancer, researchers at Yale School of Medicine are studying a technology called the Yale apoptosis assay in combination with another technology, which could double the response rate to existing drugs.
Researchers at Yale School of Medicine and over 60 collaborating research sites received a $33 million grant from the National Institutes of Neurological Disorders and Stroke (NINDS) to conduct a multi-center trial examining a novel approach for treating patients with stroke.
The Bayer Pharmaceuticals Corporation has given the 2004 Bayer Award to Raymond R. Russell, M.D., assistant professor of internal medicine in the section of cardiology at Yale School of Medicine.
A special supplement to the Society of Nuclear Medicine's Journal of Nuclear Medicine examines current and future uses of radionuclide therapy and its importance in medical practice and patient management.
Maureen A. Callaghan, MD, of Olympia, Wash. and Mohammad Wasay, MBBS, MD, of Karachi, Pakistan have been selected as the American Academy of Neurology's 2004 Advocates of the Year.
Monkeys get depressed, too, and scientists hope that studying them could lead to better treatments for depressed people. Researchers from Wake Forest University Baptist Medical Center will report new findings about patterns of depression in monkeys in the April issue of the Journal of Biological Psychology. The article is now available on-line.
While there are essentially no disparities in general intelligence between the sexes, a UC Irvine study has found significant differences in brain areas where males and females manifest their intelligence.
Results of large clinical trial -- Indiana University School of Medicine, University of Michigan and Johns Hopkins University researchers confirm that selective serotonin reuptake inhibitor antidepressants may hinder the effectiveness of tamoxifen.
A study showed that more physically fit women have better blood clotting profiles than unfit women. Three measures of the hemostatic (blood clotting) system previously linked to heart attacks were more positive for fit women, and "the bottom line is it's usually a blood clot that causes a heart attack," the lead researcher notes. The study also looked at hormone replacement therapy, which was less strongly related to the cardioprotective measures than fitness.
Reduced blood concentrations of a protein specific to fat tissue called adiponectin appear to indicate a significant risk of cardiovascular disease in one of the first studies to focus on risk of the disorder among patients with diabetes mellitus type 1, previously known as juvenile diabetes. Results of the study are published in the January issue of Diabetologia, a leading journal affiliated with the European Association for the Study of Diabetes.
The NHS recommends regular medication reviews for older patients, yet a study published on bmj.com today finds that home based monitoring does not keep older people out of hospital.
