A new study by UC Berkeley scientists finds that male sweat contains a chemical called androstadienone, which increases cortisol levels and affects women's hormonal balance. The study suggests that inhaling this chemical could be used to raise cortisol levels in patients with diseases like Addison's disease.
A new study found that patients who received aprotinin during coronary artery bypass graft surgery had a higher risk of death over five years compared to those who did not receive the drug. The study, published in JAMA, also found that safer alternatives like aminocaproic acid and tranexamic acid were available.
A new study finds that immigration has contributed to declines in interracial marriages in the US, particularly among Hispanic and Asian Americans. Education plays a key role in defining who participates in interracial marriages, with highly educated individuals more likely to cross racial lines to marry. African American intermarriage...
Studies by LA BioMed researchers found that close contacts of patients with CA-MRSA infection may be at higher risk of acquiring an infection. The findings suggest that CA-MRSA strains are more transmissible than traditional S. aureus strains, emphasizing the need for cautious treatment and contact isolation.
A study found 5 genetic variations associated with the risk of nonfatal venous thrombosis in postmenopausal women, highlighting potential new targets for prevention and treatment. The findings suggest that genetic factors may play a significant role in the development of this condition.
The Pediatric Exclusivity Program has generated over 300 pediatric studies and labeling changes for more than 115 products. The program's economic return is highly variable among products, with blockbuster medications producing substantial profits while others yield modest returns.
Aging animals show reduced AMPK activity in skeletal muscle, leading to decreased mitochondrial function and increased intracellular fat content. This decline contributes to insulin resistance and type 2 diabetes.
Researchers found that housekeepers' perceived levels of exercise positively impacted their health, with significant weight loss and improved blood pressure. The study suggests the placebo effect plays a role in exercise's benefits.
A recent study suggests that overactive bladder is less common in Finland than previously thought. The condition was identified in 6.5% of men and 9.3% of women, with urinary frequency and nocturia being more prevalent among those with the condition.
Renowned nutrition expert Dr. Irwin Rosenberg emphasizes the need for more research on vitamins and minerals, highlighting the limitations of current evidence. He advocates for standardized regulations on multivitamin products to ensure customer safety and informed marketing.
Researchers discover xanthine oxidoreductase (XOR) as a key player in early fat cell development, suggesting potential for new obesity treatment. XOR inhibition blocks fat formation and improves metabolic outcomes in mice.
A study published in the Journal of the National Cancer Institute found that women with breast cancer who received growth factors during chemotherapy had a higher risk of developing leukemia or myelodysplastic syndrome. The absolute risk is small, but it should be considered when making treatment decisions.
A new report by the European Society for Medical Oncology warns that Europe's aging population is driving a major increase in cancer cases and deaths. The report estimates that there were 3.2 million new cancer cases diagnosed in 2006, with lung cancer remaining the leading cause of death.
A new study found that hairy cell leukemia survivors have an increased risk of developing certain cancers, including Hodgkin lymphoma and thyroid cancer. Meanwhile, a new test may be able to identify patients with a specific type of gene mutation that indicates an inherited form of colorectal cancer or potential response to certain drugs.
A study by Durham University found that nearly two-thirds of English mortgage holders have almost all their savings tied to their home. This means nearly a quarter are taking a diversified approach, balancing investments between home ownership and other financial portfolios.
Researchers have developed a novel approach for the direct synthesis of polymeric nanocapsules with surface elements that can recognize specific target cells. The method uses disk-shaped monomers with polymerizable groups, which link together to form hollow spheres with uniform sizes and tailored surfaces.
A recent study finds that human population size and affluence are the primary drivers of environmental stressors, whereas urbanization, economic structure, and age of population have limited impact. The researchers used global average productivity to compare environmental tradeoffs and human-induced stressors in the environment.
Researchers at the University of Rochester found that playing action video games for 30 hours per week improved spatial resolution and visual acuity. The study showed significant improvements in identifying letters presented in clutter, even beyond the part of the visual field where players typically engage with the game.
The new guidelines emphasize the importance of treating both diabetes and cardiovascular diseases simultaneously. The guidelines recommend using stress testing and echocardiography to confirm a diagnosis of valvular heart disease, and emphasize the need for precise risk stratification before treatment decisions are made.
