A large clinical trial found that tamoxifen does not increase cardiovascular risk in healthy women or those with coronary heart disease. Women who received tamoxifen had the same rate of cardiovascular events as those receiving a placebo, regardless of prior heart problems.
Local Gypsy minority self-governments drive local development efforts, improving socio-economic conditions and strengthening intracommunity social ties. These initiatives benefit not only Roma but also other ethnic Hungarians, fostering a more pluralistic, democratic society.
Researchers at Ohio State University have created a new way to map ocean currents using a single video camera with special software, comparing favorably to expensive electronic sensors. This method could help scientists better understand erosion and develop effective management strategies.
Research at Ohio State University found that having a same-sex friend present during a stressful event can increase cholesterol levels in women, countering previous studies on the benefits of social support. The study involved 40 healthy college-aged women who gave a speech with and without a friend.
A genetic defect in the alpha-1 antitrypsin gene is associated with a threefold increased risk of developing sporadic colorectal cancer. Carriers who smoke have a significantly higher risk of developing this type of cancer compared to non-smokers.
Scientists have discovered that ancient underground fractures in Ohio soil can contaminate water supplies quickly, posing a threat to the state's groundwater. Research suggests that these fractures allow contaminated water to bypass purification and travel through the soil, potentially endangering water sources.
Scientists aim to develop novel optical imaging technique to capture detailed images of large numbers of brain neurons. The project, led by Leif H. Finkel, brings together experts in bioengineering, neuroscience and physics to overcome limitations of current techniques, enabling study of neural network activity changes with learning.
Researchers found that half of patients admitted to hospital with life-threatening symptoms of heart failure had diastolic heart failure, a previously under-studied disorder. The study emphasizes the need for further research into treatment options for this common form of heart failure.
A new study found that women are more likely to exercise if they have social support from family, while men need the support of friends. The study also revealed that students who believe in their ability to participate in exercise regularly tend to be more active.
A new program at the University of North Carolina at Chapel Hill aims to eliminate health disparities between blacks and whites. Researchers will focus on prostate cancer, high blood pressure, and sexually transmitted diseases, with a goal of finding ways to reverse the effects of racial disparities.
A Yale researcher found that brain activity is consistently present in the background, contradicting cognitive theories. The study highlights the need for a more holistic approach to understanding brain function and bridging the gap between psychiatric and neuroscientific views.
The article highlights the need to shift from aggressive treatment to palliative care in hospitals and healthcare facilities, improving quality of life for dying patients. Strategies can be implemented to reduce suffering by involving a multidimensional approach to care.
A study confirms that preventive occupational therapy can aid older persons in staying healthier and more independent. The research found that participants who received individualized treatment by an occupational therapist sustained 90% of therapeutic improvements after six months of non-intervention.
A new study by NC State University professor Dr. John L. Hubisz found significant errors in widely used middle school physical science textbooks, including incorrect statements about Newton's first law of motion and the equator's location. The study also criticized textbook layout, exercises, and the lack of clear authors.
Scientists have found a link between the combination of two widely used agricultural pesticides and Parkinson's disease in mice. The study, led by Deborah Cory-Slechta, suggests that everyday environmental factors may play a role in the development of the disease.
A new study suggests that scenario-based counseling can help patients seek hospital care sooner after a heart attack, potentially improving survival rates. The intervention teaches patients to recognize the diversity of symptoms and address emotional responses to a heart attack threat.
The American Geophysical Union has named Robert C. Cowen its award for sustained achievement in science journalism, recognizing his 50-year career as a science writer and editor at The Christian Science Monitor. The award honors Cowen's contribution to the public understanding of science.
A study found that weight loss lowered high-normal blood pressure in overweight adults, but only a small percentage maintained substantial weight loss over three years. Another study discovered that scuba diving increases the risk of brain lesions due to decompression illnesses and heart abnormalities.
A new study published in JAMA found that steroid hormone drug fludrocortisone does not alleviate symptoms of chronic fatigue syndrome (CFS), particularly neurally mediated hypotension (NMH). Researchers recommend further testing of other drugs or drug combinations to benefit CFS patients with NMH.
At the American Astronomical Society meeting, NSF highlighted recent breakthroughs in adaptive optics, revealing a solar-system-sized disk around a massive protostar. The NOAO Deep Wide-Field Survey also captured 300,000 faint galaxies over a vast area, creating the first three-dimensional map of the universe.
A Johns Hopkins Children's Center study failed to link autistic children's sensory fixation to brain damage, contradicting long-held theories. The study found that the cerebellum's balance regulation function operates normally in high-functioning autistic children.
Researchers at University of Wisconsin-Madison have identified the genetic basis of Alexander disease, a rare and devastating childhood brain disorder. The discovery confirms mutations in the GFAP gene as the cause, leading to an abnormal protein buildup that damages the nervous system.
A new study found that deaf children who receive cochlear implants at a young age have better speech recognition skills than those who wait longer. The research suggests that early implantation is crucial for language development and can improve communication skills in children with hearing impairments.
