A new study by scientists at Fred Hutchinson Cancer Research Center provides insight into why some men develop aggressive prostate cancer that becomes resistant to hormone-withdrawal therapy, a common form of treatment.
Parts of the human brain think about the same word differently, at least when it comes to prepositions, according to new language research in stroke patients conducted by scientists at Purdue University and the University of Iowa.
Jack E. Dixon, Professor and Dean of Scientific Affairs at the University of California, San Diego School of Medicine, has been selected to receive the 2005 ASBMB-Merck Award in recognition of his outstanding contributions to research in biochemistry and molecular biology. Dr. Dixon will present his award lecture on protein tyrosine phosphatases at 4:45 p.m. on Sunday, April 3 at the American Society for Biochemistry and Molecular Biology (ASBMB) Annual Meeting in San Diego.
There's a reason why we listen to music on the FM dial of our radios - it just sounds better than it does on AM. And this reason also holds true for cochlear implants and hearing aids. UC Irvine School of Medicine researchers have found that improving frequency modulation, or FM, reception on cochlear implants and hearing aids may increase the quality of life for the millions of Americans who use these devices.
Rice University bioengineer Antonios Mikos has been awarded the prestigious Marshall R. Urist Award by the Orhopaedic Research Society for his cutting-edge research in tissue regeneration. Mikos, the John W. Cox Professor of Bioengineering, professor of chemical engineering and director of Rice's Center for Excellence in Tissue Engineering, is a pioneer in fabricating synthetic materials with tailored chemistries for specific tissue-engineered repair of orthopaedic injuries.
The workshop is designed to educate participants on the challenges and importance of getting accurate and timely information to the public during a crisis.
Many people with fibromyalgia and other chronic pain conditions fear that activity will make their pain worse. But new research suggests they may be able to be more active than they think - - without suffering from increased pain.
Researchers are investigating how air travel can be adapted to ease its impact on the environment.
Jumping on that treadmill or bike is not only good for one's health, but also can help significantly reduce depression, researchers at UT Southwestern Medical Center have found..The first study to look at exercise alone in treating mild to moderate depression in adults aged 20 to 45 showed that depressive symptoms were reduced almost 50 percent in individuals who participated in 30-minute aerobic exercise sessions three to five times a week.
Whole-body CT screening may lead to an estimated average increase in life expectancy of only six days, at a cost of $151,000 per life-year gained.
Each year, more than 600,000 people in the U.S. suffer from pulmonary embolism, and 60,000 cases are fatal. Most pulmonary emboli occur when a blood clot breaks free from the leg and travels to the lung. Performing CT venography of the legs in cases of suspected pulmonary embolism can increase detection of thromboembolic disease by 20 percent.
A new technique devised by UC Irvine researchers can greatly facilitate the development of vaccines against infectious diseases such as smallpox, malaria and tuberculosis. Because the new technique can synthesize a large number of proteins very quickly, it has potential to accelerate vaccine development, particularly crucial in the fight against bioterrorism.
Surprising findings in the Journal of the American College of Cardiology show the basic biochemical composition of heart valves in patients with congestive heart failure are markedly different than those with healthy hearts. This may explain the mixed success of surgery to repair valve dysfunction in these patients. The new study suggests that changes in the valves themselves may contribute to the problem of mitral regurgitation, or failure of the valves to close properly.
By age six, children of overweight mothers are fifteen times more likely to be obese than children of lean mothers. The research, at The Children's Hospital of Philadelphia and the University of Pennsylvania, showed the strength of genetic influences, and suggests that efforts to prevent obesity should focus on such children at risk, preferably by four years of age.
Lack of the enzyme, acetyl CoA carboxylase 2 or ACC2, appears to turn the adipose or fat cells of mice into fat burners, explaining in part why the animals can eat more and weigh less than their normal counterparts, said Baylor College of Medicine researchers.The report that appears online today in the Proceedings of the National Academy of Sciences.
For the first time, researchers have automatically grouped fluorescently tagged proteins from high-resolution images of cells. This technical feat opens a new way to identify disease proteins and drug targets by helping to show which proteins cluster together inside a cell. Developed by Carnegie Mellon University, the approach outperforms existing visual methods to localize proteins inside cells, says Robert F. Murphy, whose report is in an upcoming issue of the Journal of Biomedicine and Biotechnology.
Primary-care physicians who encourage their patients to let them know about bothersome side effects of prescribed medications -- and who address such problems promptly -- can reduce the chances that patients will be harmed by the medications, according to a new study by researchers in Boston.
For the first time, sociologists have mapped the romantic and sexual relationships of an entire high school over 18 months, providing evidence that these adolescent networks may be structured differently than researchers previously thought. The results showed that, unlike many adult networks, there was no core group of very sexually active people at the high school.
The best strategy for minimizing future influenza morbidity and mortality would be to concentrate vaccinations in school children and high-risk groups, according to a new research commentary by scientists at Emory University. The alternative vaccine plan is based on mathematical models and on influenza field studies.
A large clinical trial of a novel HIV vaccine has begun enrolling volunteers at sites in North America, South America, the Caribbean and Australia. Organizers are seeking 1,500 participants.The trial is co-funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), and the pharmaceutical company Merck & Co. Inc.
Excessive weight can bring with it many medical problems, including insulin resistance and often type 2 diabetes. Biliopancreatic diversion surgery for severely obese patients leads to more improved insulin sensitivity when compared to gastric bypass surgery.
Researchers from the Johns Hopkins Bloomberg School of Public Health found that living in a disadvantaged urban neighborhood can increase male residents' risk of contracting HIV. The study related disadvantaged neighborhoods to stress and stress to increased injection drug use in male study participants.
Adults under the age of 50 who have chronic pain may be less able to cope with their condition and more prone to associated depression than their elders, a new study suggests. And the same "generation gap" pattern exists among both blacks and whites, though previous studies have shown blacks experience more pain and more pain-related negative effects than whites.
Mission controllers cross their fingers whenever the Sun is stormy and their spacecraft have to fly over the South Atlantic. There, even satellites in low orbits suffer many hits by atomic bullets from the Sun. Troublesome faults occur in electronic systems and astronauts see flashes in their eyes. The Earth's magnetic field, which shields our planet against charged atomic particles coming from outer space, is curiously weak in that region.
Ultra-realistic surround sound is a step closer for everyone thanks to a new method that will cheaply and efficiently compute the way individuals hear things.The research could have applications in areas ranging from wearable computers to hearing aids.
