A study of nearly 2,000 adults aged 18-90 found that higher education delayed the onset of depression by approximately ten years. This is because better physical health helps mitigate depression risk.
A study by Scott Coffey found that cocaine withdrawal symptoms are relatively mild and decrease steadily over time, with improvements in depression, anxiety, and energy levels.
A new study using a decision analysis model found that sildenafil was as cost-effective as kidney dialysis, cholesterol lowering medication or coronary artery bypass surgery. An editorial questions whether health insurance should cover treatment for erectile dysfunction when many Americans are not covered.
A new diet study, funded by Duke University Medical Center, aims to test the hypothesis that reducing fat intake can halt or slow diabetes progression. Participants will consume specially prepared foods with Olestra instead of real fat, allowing researchers to study a low-fat diet independently from a low-calorie diet.
Researchers at UCSD develop a new drug-combination therapy using tamoxifen and cisplatin, significantly improving survival rates for patients with metastatic melanoma. The treatment results in a 62% reduction in tumor recurrence after five years.
The National Sea Grant College Program has released a 70-page guide to salmon issues in the Pacific Northwest, providing basic resources for news media covering the salmon management debate. The guide lists Sea Grant-funded researchers, contact information for agencies and organizations, and web-based resources.
Scientists have created a novel dinucleotide molecule that appears to outlast existing treatments in cells. The integrase inhibitor has the potential to prevent HIV infection by blocking its ability to replicate in non-infected human cells.
Researchers at Carnegie Mellon University found that the human brain employs surprising economies of effort in problem-solving by minimizing mental workload. The study used fMRI scans to identify brain activation patterns for verbal and visual thinking strategies.
Scientists at UCSF deciphered a pattern of signals that determine the survival of T cells, the body's natural defense arsenal. The research identifies a new role for chemical messages between the immune system and a steroid hormone signal, which may control stress-induced hormone imbalance and autoimmune diseases.
Researchers at Duke University Medical Center developed a tumor-specific antibody, Y10, that targets mutated protein found only in cancer cells. This antibody can eradicate brain tumors in mice and has shown promise as a potential treatment for human patients.
Researchers have directly observed magnetic field line shrinkage or reconnection outflow during solar flares, resolving a long-standing mystery. The discovery sheds light on the behavior of magnetic fields in solar flares and their impact on space weather.
The Kaposi's sarcoma virus employs a novel strategy to evade the immune system by removing sentries on cell surfaces and shipping them for destruction. Researchers identified two viral genes that reduce MHC-1 proteins at the cell surface, allowing the virus to spread more widely.
Loren Acton, a former astronaut and solar physicist, has won the prestigious George Ellery Hale Prize for his outstanding contributions to solar astronomy. Acton's research focuses on understanding the Sun's behavior, shapes, colors, and motions.
A study found that residents of disadvantaged neighborhoods experience higher levels of depression due to the presence of disorder and social control breakdown. The researcher discovered that residents living in such areas report feeling distressed by high levels of crime, graffiti, and vandalism, as well as a lack of safety.
Patients with chronic heart failure who underwent exercise training showed significant improvements in left ventricular function and blood circulation, including increased stroke volume and reduced heart enlargement. Long-term exercise training was also associated with a reduction in total peripheral resistance.
Establishing stroke centers in hospitals can significantly improve outcomes for stroke patients by dedicating resources to diagnose and treat stroke patients within the critical 3-hour time period. The Brain Attack Coalition recommends primary and comprehensive stroke centers to provide emergency care and extensive care, respectively.
