A study by the University of Pennsylvania School of Medicine found that telling a lie and telling the truth require distinct brain activities. The research used fMRI to track brain activity in volunteers during an interrogation method, revealing increased activity in regions involved in inhibition and control when lying.
A study found that young athletes are more prone to sudden death due to cardiovascular diseases, with a higher risk of 2.5 times compared to non-athletes. Enhanced pre-participation screening methods, including electrocardiograms, are recommended to identify affected athletes.
Researchers at University of Pittsburgh identified Langerhans cell precursors that can be targeted to initiate or down-regulate the immune response, potentially leading to novel treatments for asthma and transplant rejection. The discovery could also enhance vaccine development.
A new handheld echocardiography device has been shown to detect heart abnormalities with minimal training, offering a major step forward in heart health screening. The device can reasonably detect left ventricular dysfunction and pericardial effusion, but may require additional training for other conditions.
UB researchers found that Ritalin can cause long-lasting changes in brain cell structure and function, similar to other stimulant drugs. The study suggests that Ritalin's effects may outlast the initial dose, leading to concerns about its long-term impact on the brain.
Researchers analyzed 20 years of US vital statistics data to find racial disparities in heart disease mortality rates. The study confirmed that African Americans experienced a slower decline in CHD death rates, highlighting the need for targeted prevention programs.
Researchers report significant advancements in sutureless vascular graft surgery, reducing operating time by up to 90%. The new techniques enable quicker connections of blood vessels and minimize damage to the heart, paving the way for minimally invasive surgery on the beating heart.
Researchers have successfully converted adult human bone marrow stem cells into functional brain cells in the lab, using a combination of growth factors and nutrients. The breakthrough could potentially lead to new treatments for neurodegenerative diseases like Parkinson's disease.
