Research reported today should provide relief to women who are worried after a relative's breast cancer diagnosis. The study in the open access journal BMC Cancer shows that a family history of breast cancer does not give a useful indication of the likelihood that a woman will develop it herself at an early age.
A new fossil discovery- the first of its kind from the whole of the Antarctic continent- provides scientists with new evidence to support the theory that the polar region was once much warmer.
The discovery by an international team of scientists is published today (**Embargoed until 00.01 BST Wednesday 23 July**) in Proceedings of the Royal Society B. It involved researchers from the University of Leicester, North Dakota State University, the British Geological Survey, Queen Mary University of London, and Boston University.
BOSTON, Mass. (July 23, 2008)— Ever since the human genome was sequenced less than 10 years ago, researchers have been able to access a dizzying plethora of genomic information with a simple click of a mouse. This digitizing of genomic data—and its public access—is something that would have been unthinkable a generation earlier.
Drug abuse accounts for a third of the deaths behind Scotland's higher mortality rate, according to a study published on bmj.com today.
We are continuously bombarded with messages about the dangers of too much sun and the increased risk of melanoma (the less common and deadliest form of skin cancer), but are these dangers real, or is staying out of the sun causing us more harm than good?
Two experts debate the issue on BMJ.com today.
Women with sexual dysfunction caused by the use of antidepressants experienced a reduction in adverse sexual effects with use of sildenafil, commonly known as the erectile dysfunction medication Viagra, according to a study in the July 23/30 issue of JAMA.
Human immunodeficiency virus (HIV) care and treatment programs in resource-limited settings must aggressively address tuberculosis (TB) and the emerging multidrug-resistant TB epidemic to save patient lives and to curb the global TB burden, a major cause of death for persons with HIV, according to an article in the July 23/30 issue of JAMA.
ANN ARBOR, Mich. — If an influenza pandemic hits the United States, acute care hospitals are likely to be overwhelmed. Nursing homes may then be expected to assist with the patient overflow, but a new study in the Journal of the American Medical Association suggests that many are not prepared for such a task.
CLEVELAND – Researchers at Case Western Reserve University have developed a technique that has the potential to deliver cancer-fighting drugs to diseased areas within hours, as opposed to the two days it currently takes for existing delivery systems.
Using laboratory mice, drug delivery time from injection to the cancer cells was reduced from two days to mere hours. Using this as a model for potential human use, cancer patients may someday soon receive the benefits of cancer-fighting drugs within hours of injection.
Papers delivered at three conferences in the US and Europe this summer report on new research at the University of Southern California Viterbi School of Engineering studying interactions of children with Autism Spectrum Disorders (ASD) with bubble-blowing robots.
The preliminary studies, by Professor Maja Matarić and PhD student David Feil-Seifer of the USC Interaction Laboratory, confirm what has been widely reported anecdotally: that ASD children in many cases interact more easily with mechanical devices than with humans.
Volunteering for environmental protection activities can be physically and mentally sustaining for older people, according to the latest issue of Public Policy & Aging Report (PPAR). In fact, this demographic group is in a unique position to have a noticeable impact on its surroundings.
INDIANAPOLIS – Although a growing body of research supports a link between effective communication and patient, family and physician satisfaction, doctors, including oncologists and other specialists who frequently care for terminal patients, do not routinely receive training in end-of-life conversations during medical school, residency training, or after they start to practice medicine.
BIRMINGHAM, Ala. – Proven combinations of medicines and the introduction of new anti-arthritis drugs have significantly improved the treatment of rheumatoid arthritis (RA), according to guidelines issued by the American College of Rheumatology and co-authored by physicians at the University of Alabama at Birmingham (UAB).
Lead author Kenneth Saag, M.D., M.Sc., a professor in the UAB Division of Clinical Immunology and Rheumatology, said the new guidelines update strategies for treating RA with the goal of preventing joint damage and disability.
BOZEMAN – Montana State University microbiologist Matthew Fields spends his days studying a microscopic world that most people take for granted.
Fields studies the physiology and behavior of microbes – the tiny organisms that have inhabited virtually every square inch of the earth's surface for the past four billion years.
"Microbes have global impact," Fields said. "They grow fast and in large numbers, and there is always power in numbers."
