At this public symposium, which will take place during the 143rd annual meeting of the National Academy of Sciences, a panel of experts will discuss the impact of scientific approaches to validating evidence -- such as fingerprints, DNA, photographs, and memory -- on the U.S. justice system.
A report in the Journal of Orthopaedic Research suggests a better way to repair tears to the anterior cruciate ligament (ACL), a knee injury suffered by more than 100,000 Americans each year, particularly girls. Hospital Boston surgeon Martha Murray, MD reports that a collagen gel, enriched with blood platelets, can stimulate natural healing of a partial ACL tear, encouraging the body's cells to fill in the defect and restore mechanical strength to the ligament.
Researchers at Mayo Clinic have narrowed the search for effective prostate cancer biomarkers (genetic variations that point to a specific disease or condition), identifying changes in the expression of genes of the whole genome closely correlated to prostate cancer development and progression.
The American Physiological Society, with the support of the National Institute of Diabetes and Digestive and Kidney Disease and the National Institute of General Medical Sciences, is providing a total of $90,000 in fellowships to underrepresented minority students to attend APS scientific conferences, including Experimental Biology 2006 (EB) in San Francisco April 1-5. The program aims to retain qualified minority students in physiology and other biomedical sciences by offering networking and career opportunities.
For more than a decade space-based radar instruments have been routinely observing ocean surface phenomena including wind, waves, oil slicks, even the eyes of hurricanes. Now - employing the same principle as police speed guns - satellite radar has also begun to enable direct measurements of the speed of the moving ocean surface itself.
Bernard Fisher, M.D., the renowned clinical cancer researcher whose career has been dedicated toward improving survival as well as quality of life for women with breast cancer, will receive the American Association for Cancer Research Award for Lifetime Achievement in Cancer Research.
Amgen (NASDAQ: AMGN), the world's largest biotechnology company, today announced the U.S. Food and Drug Administration (FDA) has approved every-three-week dosing of Aranesp. (darbepoetin alfa) for the treatment of chemotherapy-induced anemia (low red blood cell count) in patients with non-myeloid malignancies.
Each year at its Annual Meeting, the American Association for Cancer Research gives special recognition to distinguished individuals whoseefforts and dedication have helped to increase awareness about the importance of cancer research.
Bolstered by recent laboratory findings, researchers at the University of Rochester Medical Center are embarking on a National Institutes of Health-funded clinical study to better understand the deceptive role environmental lead exposure plays in bone maturation and loss. The clinical trial is the latest in a growing body of research that is putting yet one more notch in the belt of diseases attributed to lead, and this time, researchers say, its target is older adults at risk for osteoporosis.
A new mouse model technology has been developed to enable investigators to induce melanoma with specific cancer 'antigens' - the targets of vaccines against cancer.
Elsevier, a world-leading healthcare and scientific publisher, announced today the launch of its new drug tracking and analysis tool, Inteleos. To meet the demanding requirements of business intelligence, market research and business development professionals, Elsevier has developed a database of over 8,000 drugs and 1,200 pharmaceutical and biotech companies.
A breakthrough self-assembly technique for growing replacement cartilage offers the first hope of replacing the entire articular surface of knees damaged by arthritis. The technique, developed at Rice University's Musculoskeletal Bioengineering Laboratory, is described in this month's issue of the journal Tissue Engineering. In follow-up research, Rice's team has used rabbit cells to grow the entire articular surface of the distal femur.
Government policies in Burma that restrict public health and humanitarian aid have created an environment where AIDS, drug-resistant tuberculosis, malaria and bird flu (H5N1) are spreading unchecked, according to a report by researchers at the Johns Hopkins Bloomberg School of Public Health. In that report, the authors document the spread of these infectious diseases, which if left unchecked, could pose a serious health threat to other Southeast Asia nations and the world.
This international multidisciplinaryconference is aimed at exploring the discovery and production of microbially derived natural products, which since the discovery of penicillin and other antibiotics in the mid-1900s have become a mainstay of the pharmaceutical industry.
Men with prostate cancer generally make treatment decisions based on differences in the information they receive rather than their own preferences, according to a new review.
Weight training significantly improves the quality of life of women recently treated for breast cancer, according to a new study.
With Mars and moon again targets, Ball State-Marquette study shows Soviet-US minus 6-degree bedrest decline produced the same swift drop in the cardiorespiratory system's ability to support exercise as astronauts experienced on a 17-day spaceflight. In the first "head-to-head" comparison in the history of spaceflight, the Journal of Applied Physiology paper reported a 10 percent drop. Since spaceflight and bedrest yield similar results, astronaut safety and earthbound medical applications can be developed in either environment.
In an effort to fight high rates of diabetes and obesity, chemists are exploring a variety of sugar alternatives -- including new artificial sweeteners and sweetness enhancers -- to satisfy America's demand for sweet flavor with fewer health risks. These and other taste-related topics will be discussed by some of the world's top experts during a three and one-half day symposium, "Sweetness and Sweeteners," March 27-30, in Atlanta at the national meeting of the American Chemical Society.
Researchers are using an innovative, multi-functional sensing tool to investigate adenosine triposphate (ATP) release and its role in cystic fibrosis. The ATP study marks the first application of a novel sensing system developed by a research team led by Christine Kranz at the Georgia Institute of Technology.
Grape seed extract lowered the blood pressure of patients who participated in a UC Davis study of the benefits of the supplement on people with high blood pressure.
A light-sensitive, self-assembled monolayer that provides unique control over particle interactions has been developed by scientists at the University of Illinois at Urbana-Champaign. Particles coated with the monolayer change their surface charge and chemistry upon exposure to ultraviolet light.
Psychologists wanting to help old people safely cross the street and otherwise ambulate around this busy world have found that from age 70 and up, safe walking may require solid "executive control" (which includes attention) and memory skills. For the old, slow gait is a significant risk factor for falls, many of which result in disabling fractures, loss of independence or even death.
Using principles of green chemistry, scientists are designing materials and processes that provide the maximum benefits of nanotechnology while minimizing potential hazards. Green nanochemistry will be featured during a four-day symposium, "Nanotechnology and the Environment," March 26-29, at the 231st national meeting of the American Chemical Society, the world's largest scientific society. The symposium will also address applications of nanotechnology in medicine, electronics and energy.
Researchers have developed "custom" nanoparticles that show promise of providing a more targeted and effective delivery of anticancer drugs than conventional medications or any of the earlier attempts to fight cancer with nanoparticles. The nanoparticles also have the potential to reduce side effects associated with chemotherapy by avoiding healthy cells, the researchers say. Their study will be presented March 26 in Atlanta at the 231st national meeting of the American Chemical Society.
In diverse ecosystems, packed with wildly different species, evolution whizzes along. As different species accumulate mutations, some adapt particularly well to their environment and prosper. It happens in marine sediments, mountain forests - and, as a new study from The Wistar Institute illustrates, in precancerous tumors, too.
