Researchers have discovered a new anti-inflammatory drug, NCX-2216, that effectively removes excess amyloid protein from the brains of mice with Alzheimer's-like memory disorders. The nitro-NSAID also activates immune cells called microglia, which may help remove amyloid before it hardens into toxic plaques.
A recent study by Mayo Clinic researchers found that patients with alcoholic-liver disease are at a higher risk of developing confusion and delirium after liver transplant surgery. The study, which included 87 patients, revealed that the length of sobriety before surgery is directly correlated to the severity of these complications.
Children exposed to two or more pets during their first year of life were on average 66-77% less likely to develop allergic antibodies, a significant finding that challenges current understanding of allergy development.
Scientists have found tiny bugs living inside mealybugs, which could aid in pest control efforts. The discovery also reveals a complex relationship between the insects and their bacteria, potentially leading to new methods of species identification.
A U.Va. study is investigating the effectiveness of echinacea in treating colds by standardizing extracts from the plant. The researchers plan to recruit approximately 450 subjects and administer three different concentrations of echinacea constitutents to test their impact on viral replication and inflammatory responses.
Scientists have gained valuable insights into AIDS by studying the simian immunodeficiency virus in monkeys. Researchers are now exploring ways to vaccinate against HIV transmission and eliminate latent viruses.
The LSU Museum of Natural Science is part of a $4 million grant to compare DNA sequences of 500 bird species. The goal is to understand the history of avian diversity and reconstruct the evolution of bird behavior, morphology, and ecology.
A study by National Space Biomedical Research Institute found that amino acid supplements can maintain protein synthesis rates and body mass during bed rest, a model for muscle loss in space. The supplements also showed potential in reducing muscle atrophy in elderly, burn patients, and those after major operations.
Researchers at the University of Illinois at Urbana-Champaign have found several new pieces to the puzzle of high-temperature superconductors by imaging the copper-oxide plane. They discovered that the surface behavior is different from when buried inside the crystal, offering additional insight into high-temperature superconductors.
A new study demonstrates that pig cells can be transplanted into children with type 1 diabetes without the need for immunosuppressive drugs, resulting in some patients being off insulin. The use of embryonic stem cells and novel preservation methods also holds promise for increasing the availability of viable cells for transplantation.
A USF/UCLA study shows that healthy humans who smoke marijuana alter the expression of marijuana receptors on immune cells in their blood. The findings suggest that cannabinoids might benefit someone with chronic inflammatory disease but not those with a chronic infectious disease like HIV infection.
A study found that children exposed to dogs and cats in the home have a significantly reduced risk of developing common allergies, with exposure levels reducing allergy rates by up to 45%. The research suggests that early exposure to endotoxins from pets may help the immune system develop a different response, making it less likely for...
Virginia Tech and ICSRC used Internet2 technology to create a live virtual classroom environment where students from Seattle interacted with teachers on the east and west coast. The ThinkQuest conference explored emerging technologies and educational ideas, with participants debating future possibilities for K-12 audiences.
Dr. Barbara Block, a MacArthur Award winner, will present the Scholander Award for outstanding research on comparative physiology. The award recognizes her work on tuna migration patterns using satellite-based tagging technology, which has implications for preserving tuna species and managing fisheries.
Research identifies young women with breast cancer at increased risk of ovarian cancer, including those with BRCA1 and BRCA2 gene mutations. The study suggests that these women may benefit from prophylactic oophorectomy or counseling.
A new study reveals that climate change has strengthened the connection between El Nino-Southern Oscillation (ENSO) and cholera cycles, leading to increased disease outbreaks in warmer years. The researchers found that ENSO events trigger cholera increases after warm events and decreases after cold events.
A new system integrating wireless technology reduces clinical errors by providing real-time access to patient data, allowing medical staff to spend more time with patients. The system has been shown to decrease the time required to see each patient by 30% in post-operative acute pain management wards.
