Researchers at the University of Pennsylvania School of Medicine have created a stealth-like molecule called BSB that can effectively breach the blood-brain barrier and bind to amyloid plaques, enabling visualization using PET or SPECT imaging. This breakthrough paves the way for the refinement of BSB as a diagnostic tool for Alzheimer...
Scientists at Emory University Health Sciences Center have discovered that the oxytocin gene is necessary for forming social memories, allowing individuals to recognize familiar faces. The study found that mice lacking this gene exhibited social memory deficits, which were restored with oxytocin treatment.
A team led by Dr. Charles Meegan is developing a new burst monitor to fly on the Gamma Ray Large Area Space Telescope, which will provide broad energy coverage for gamma-ray studies and help solve the nature of gamma-ray bursts.
A community program in rural Maine associated with a significant decrease in heart disease death rates, thanks to its comprehensive approach to tracking patient risk factors and providing lifestyle education. The study suggests that such programs can be an effective way to blunt the worldwide cardiovascular disease epidemic.
A recent study reveals that primary care practices neglect to counsel diabetic patients on how to self-manage their illness, leading to a lack of comprehensive disease management. Despite this, patients who utilized community resources for support received more medical and counseling-related services from their physicians.
A study found that two methods to increase physical activity among sedentary adults were comparable in effectiveness but differed in cost-effectiveness. The lifestyle approach, which taught problem-solving and self-management skills, was more cost-effective, averaging $17/month over a two-year period.
Research reveals that child accident victims experience post-traumatic stress disorder (PTSD) more frequently than previously thought, with symptoms often overlooked by adults. The study emphasizes the need for better education programs to recognize subtle signs of PTSD in children.
Boston College scientist Kevin G. Harrison proposes the Silica Hypothesis, which suggests that increasing ocean silica levels can remove carbon dioxide from the atmosphere, slowing global warming. This mechanism may be responsible for decreased atmospheric CO2 levels during glacial times and could be relevant to today's climate change.
A new study found that underage college drinkers are more likely to drink in private settings and obtain alcohol inexpensively. Underage students also reported consuming more drinks per occasion and experiencing more alcohol-related problems compared to their older peers.
Researchers found that tetrahydrocannabinol (THC) promotes tumor growth by impairing the immune system, increasing IL-10 and TGF-beta cytokine production. Marijuana smoke contains higher carcinogenic hydrocarbons than tobacco, posing a potential cancer risk.
A study found that inner-city physicians provide fewer cancer screenings and preventive services compared to higher-income communities. The researchers identified four main barriers: lack of training, time constraints, office support, and insurance reimbursement issues.
Researchers at Northwestern University have discovered that the growth-associated protein GAP-43 enhances learning and memory in the mammalian brain when overexpressed in a phosphorylatable form. This finding could lead to new treatments for memory loss and learning disorders.
