The National Institute of Dental and Craniofacial Research, part of the National Institutes of Health, has begun supporting an innovative, three-year study to compile the first full catalogue of genes found in oral biofilms, the sticky bacteria-laden films that form on our teeth and gums.
Most young Black adolescents appear to believe that their Black peers use drugs more than White or Hispanic teens, when in reality studies show that fewer Black youth use alcohol or other drugs than do youth of other ethnic groups, a Penn State researcher says.
Pharmaceutical drug companies spend upward of $25 billion per year on promoting new drugs and distributing free samples to doctors, but new research shows such marketing devices have little impact on physicians and their prescribing behavior.
Measuring bone marrow fat (BMF) along with bone mineral density (BMD) can better predict weakening of bones than either test done alone, a new study indicates.
Not only can positron emission tomography (PET) help evaluate treatment for gastrointestinal stromal tumors (GIST) by revealing biologic changes such as how the tumor processes the fuel that makes it grow, but CT can indirectly reveal biologic changes as well by analyzing the tumor's density, say researchers from The University of Texas M. D. Anderson Cancer Center in Houston.
While the federal government ponders the ethical implications of therapeutic cloning, California is blazing a trail to the future. The Golden State has caught the attention of stem-cell scientists across the world as it takes its first steps toward becoming, thanks to Proposition 71, a destination of choice for stem-cell research, with government support to the tune of $3 billion.
University of Minnesota researchers will present the promising results from adult umbilical cord blood studies for patients with cancers of the blood and bone marrow. These studies' findings provide solutions to the problems outlined in recently published studies in the New England Journal of Medicine (NEJM).
Cigarette smoke, whether first- or second-hand, complicates the careful cellular choreography of wound healing, according to a paper by University of California, Riverside researchers that was included in the 2004 Press Book of the 44th Annual Meeting of the American Society For Cell Biology (ASCB).
Drawing on experiments with blue jays, a team of University of Minnesota researchers has found what may be the evolutionary basis for impulsive behavior. The work may help explain why so many modern-day humans find it so hard to turn down an immediate reward--for example, food, money, sex or euphoria--rather than investing and waiting for a bigger reward later.
When a community finds that water it relies on for drinking or recreation contains E. coli (Escherichia coli), a bacterium found in the feces of warm-blooded animals that indicates fecal contamination, residents and officials naturally want to find the cause and fix it -- quickly. But several testing methods using E. coli to identify the sources of fecal contamination were less accurate in field application than previously reported, according to a recent US Geological Survey (USGS) report.
ASM Press announces the latest edition of its textbook Cellular Microbiology. Geared towards scientists and graduate students, the 2nd edition of this publication will serve as an invaluable reference for understanding this relatively new field of scientific research.
Terrorists might use it to mask their messages: it's called data hiding - the subject of a new book by Ali Akansu, PhD, professor of electrical and computer engineering at New Jersey Institute of Technology (NJIT).
The Cochrane Collaboration reports that the October 2004 review, 'Interactive Health Communication Applications for people with chronic disease' (1) contains errors. The authors are currently re-analysing their data and will be resubmitting their results to The Cochrane Library (2) in the future. It is expected that the revised results will be published in April 2005.
The combination of two pills -- thalidomide and dexamethasone -- may be an effective alternative to the intravenous chemotherapy commonly prescribed to patients with multiple myeloma, according to a large collaborative study conducted by the Eastern Cooperative Oncology Group and led by a Mayo Clinic investigator. More than 15,000 Americans are diagnosed annually with multiple myeloma, an incurable cancer of the bone marrow.
To examine advances in genomic medicine as well as ethical concerns, the New York Academy of Sciences. Genomic Medicine Discussion Group Section is sponsoring a meeting, Genetic Studies in Special Populations, on Wednesday, December 8 at Rockefeller University, Welch Hall.
researchers at the Stanford University School of Medicine have developed a technique that can virtually eliminate this life-threatening complication, known as graft-versus-host disease, without compromising the transplanted cells' effectiveness against cancer.
Beginning today, Endo Pharmaceuticals Inc. will initiate commercial shipments of the first and only single-dose epidural injection that can provide up to 48 hours of pain control to help ease pain for people undergoing major surgery in the United States.
Babies who never sleep on their stomachs don't learn behaviors that may lessen their risk of sudden infant death syndrome (SIDS), researchers at Washington University School of Medicine in St. Louis have found. Even so, the researchers caution that infants should always be placed on their backs to sleep.
Diabetics with mental disorders do not have as good blood sugar control as diabetics without mental illness and are more likely to suffer diabetes complications than diabetics without mental illness.
Blacks and poor individuals are more likely to be donors while whites and wealthier individuals are more likely to be recipients of many types of transplant organs, according to a new study in the November 2004 issue of the American Journal of Medicine.
A new approach to aircraft scheduling that uses computer models could allow a safe increase in airport throughput and reduce pollution. The system under development would, for the first time, provide runway controllers with advice, based on state-of-the-art computer models, on the most efficient, safe sequence in which aircraft can take-off.
Crunched for time, many parents are sending their children off to school without breakfast, but a trial program instituted in a Pennsylvania school may not only feed those in a rush, but better provide for those entitled to free and reduced price meals, according to Penn State researchers.
Sea urchin eggs, a common model for human fertility research, create a protein shield just minutes after fertilization. In Developmental Cell, Brown University biologists reveal their discovery of an enzyme that generates hydrogen peroxide, a free radical critical to this protective process. The finding illuminates a survival mechanism shared across species.
Data on tipifarnib (R115777), a compound under investigation by Johnson & Johnson Pharmaceutical Research & Development, L.L.C. for the treatment of elderly patients with newly diagnosed poor-risk acute myeloid leukemia (AML), were presented at the 46th annual meeting of the American Society of Hematology (ASH).
New research from the University of Pittsburgh shows it is not easy for the human body to adjust to dramatic time changes as experienced by those who work shifts or whose travel takes them across time zones.
