The scientific study of the nature of disease and its causes, processes, development, and consequences. Also called pathobiology.
Australia’S GPs are older, more likely to be female and write fewer prescriptions than they did a decade ago. – It’s not only the patients in GP surgeries who are getting older, according to two new reports released today by the Australian Institute of Health and Welfare and the Australian General Practice Statistics and Classification Centre, an AIHW collaborating unit located at the University of Sydney.
A promising new chemotherapy target for a deadly form of leukemia has been discovered by researchers at the Stanford University Medical Center, US. – Cancer researchers at the Stanford University School of Medicine have discovered a promising new chemotherapy target for a deadly form of leukemia. Their discovery hinges on a novel “double agent” role for a molecular signal that regulates cell growth.
A landmark study conducted in London, Canada at The University of Western Ontario and Lawson Health Research Institute shows that a routinely practiced knee surgery is ineffective at reducing joint pain or improving joint function for sufferers of osteoarthritis. – Arthroscopic surgery for osteoarthritis of the knee provides no additional benefit to optimized physical and medical therapy, revealed by researchers in a study published in the New England Journal of Medicine (NEJM) issue of Sept. 11, 2008.
There may be a way to directly create cancer stem cells in the lab so you don?t always have to purify these rare cells from patients in order to study them directly. – With a bit of genetic trickery, researchers at the Stanford University School of Medicine have turned normal skin cells into cancer stem cells, a step that will make these naturally rare cells easier to study.
Researchers identify protein that fuels ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle. – A protein that stimulates blood vessel growth worsens ovarian cancer, but its production can be stifled by a tiny bit of RNA wrapped in a fatty nanoparticle, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Journal of the National Cancer Institute.
Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002. Higher levels of education were associated with better cognitive health. – Higher levels of health education improved cognitive health among older Americans. Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002.
21% errors in pathology reports by previous unidentified pathologist in Miramichi Hospital, New Brunswick, Canada, reported by Dr. Rosemary Henderson, pathologist. – An additional review of pathology reports in Miramichi Hospital, New Brunswick is completed by Dr. Rosemary Henderson, pathologist. This review included 227 cases of prostate and breast cancer biopsies from 2004-2005. The results indicated that 18 percent of the cases had incomplete results and three percent of the cases were misdiagnosed.
Mayo Clinic analysis of two decades of autopsy results shows prevalence of coronary disease rising after the year 2000. – A Mayo Clinic analysis of two decades of autopsy results shows a long-term decline in the prevalence of coronary disease has ended and the disease may be on the upswing. The findings appear in today’s issue of Archives of Internal Medicine.
UK researchers identified more than 7 new genetic links to prostate cancer, 2 of which would be included in a new diagnostic test aimed at spotting men at risk from this disease. – 7 new sites in the human genome identified that are linked to men’s risk of developing prostate cancer, revealed by Cancer Research UK funded scientists at the Institute of Cancer Research and University of Cambridge.
DNA sequencing establishes high throughput genetic sequencing as powerful tool for pathogen discovery; technology enables improvements in screening for transplant safety. – In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, link the discovery of a new arenavirus to the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia in April 2007.
