A study by researchers at the University of Pennsylvania found that 52% of resident physicians self-prescribe medications, with 42% obtained from hospital sample closets or pharmaceutical company representatives. The practice raises concerns about lost professional objectivity and potential conflicts-of-interest.
BioNumerik Pharmaceuticals has discovered a new non-toxic platinum protecting agent, BNP7787, which substantially reduces the toxicity of platinum-type anticancer drugs. Preclinical studies show that BNP7787 increases cisplatin's antitumor activity while protecting against kidney toxicity, vomiting, and bone marrow toxicities.
A new study found that forest fragmentation allows large predators like raccoons and opossums to target ground-nesting songbirds, leading to a decline in some species. The researchers discovered that small forest fragments have a higher incidence of predation from large species, which can lead to dramatic effects on reproductive success.
David J. Kupfer, a renowned psychiatrist, received the Rhoda and Bernard Sarnat International Prize in Mental Health for his groundbreaking research on mental health treatment. His work has improved understanding of recurrent mood disorders, depression, and the relationship between biological rhythms, sleep, and depression.
A new ultrasonic scanner developed by Penn State researchers can image the interior of a material as it responds to temperature changes. The device was used to study a laminate material called PEEK, which is widely used in various consumer products, and demonstrated its ability to detect defects and monitor internal structure changes.
Researchers at Thomas Jefferson University have developed a method to reverse dangerous cerebral vasospasms. The treatment involves administering a drug that dilates cerebral blood vessels, reversing constricting effects within 30 minutes.
The Healthy Heart Handbook for Women provides women with a personal action plan to reduce major risk factors and prevent cardiovascular diseases. Key statistics reveal that many women are at risk due to smoking, high blood pressure, and obesity, highlighting the importance of making lifestyle changes.
The Institute of Medicine has elected 55 new members, bringing the total active membership to 574. The newly elected members include experts in various fields such as medicine, public health, and social sciences, who will contribute to ongoing studies on health policy issues.
Recent study examines over 100 gamma-ray bursts, finds no evidence supporting synchrotron shock model. Researchers analyze low-energy spectra to determine burst causes.
Researchers found that zebra mussel larvae die in Lake George water within a week due to low calcium levels. However, adult mussels thrive in the same conditions. The discovery provides hope for protecting the lake's ecosystem from invasive species like zebra mussels.
Researchers found that smoke directly penetrates seeds, triggering germination, and that various factors influence the process, including charred wood, Nitrogen dioxide, and soil moisture levels. The study suggests fire behavior has a significant impact on post-fire ecosystems.
Researchers at Brown University have discovered that bats can resolve sonar images with a higher quality and wider variety of orientation tasks than previously thought. Bats can process overlapping echo delays as little as two microseconds apart, resolving objects as close together as three-tenths of a millimeter.
