The discovery was made by Dr. Ole William Petersen and colleagues from the University of Copenhagen and Lawrence Berkeley National Laboratory.
A new study found that alcohol and nicotine interact in the brain's dopamine system, suggesting a link between the two addictive behaviors. Rodent studies showed that combining alcohol and nicotine increased dopamine release, while blocking nicotinic effects with mecamylamine reduced alcohol's pleasurable effects.
A study published in the Journal of Applied Physiology found that ultra-long-distance runners experience a decline in maximal voluntary force capacity due to central fatigue, but also exhibit strengthened twitch mechanical responses and unaltered M-wave characteristics.
Recent research in social informatics reveals that information and communication technologies often have unintended outcomes, such as harming group communications and exacerbating social differences. The studies highlighted the need for frameworks to expose value conflicts embedded in ICT design, but these are not widely practiced.
Researchers have found that innovative soil fertility replenishment programs can increase crop yields by two- to four-fold, providing strong evidence for their effectiveness. The programs use natural resources available in Africa, such as trees and rocks, to replenish nutrients depleted from the soil.
A recent study found that subspecialists working outside their subspecialty cared for 25% of hospitalized patients, resulting in longer lengths of stay and higher mortality rates. Patients seen by these physicians had an average length of stay up to 18% longer than those cared for by general internists.
A Harvard research team studied human running on various surface stiffnesses, finding a 12.5-fold decrease in surface stiffness led to a 12% decrease in metabolic rate and a 29% increase in leg stiffness, with support mechanics remaining unchanged.
Research found that African-American women with ovarian cancer are at a 30% increased risk of death from any cause compared to Caucasian women. The study also revealed significant differences in tumor stage, lymph node involvement, and surgery rates between the two ethnic groups. Median survival times were also shorter for African-Amer...
A Baylor College of Medicine study found that Helicobacter pylori infection is most common among children under 10, with an estimated 24.5% infected by age 18-23. The average age of first infection was 7.5 years, and over 84% of infected children remained infected during adolescence and young adulthood.
A recent study found that heightened depressive symptoms, emotional eating, and low self-esteem can predict binge-eating disorders in teenage girls. The research also revealed that low peer support increases the risk of binge eating, while parental support has no effect on this issue.
A new study suggests that galanin, previously thought to be detrimental to Alzheimer's patients, may actually enhance acetylcholine release from remaining cholinergic basal forebrain neurons. This compensatory role could delay disease progression and inform the development of galanin antagonists as a potential treatment option.
Researchers at North Carolina State University challenge dominant linguistic theories of African-American English, proposing a new model based on African-based Creole language and regional dialects. Their research, conducted in Hyde County and the Appalachian Mountains, reveals similarities between black speech and African influences.
Researchers found that mice lacking the SHIP gene survived allogeneic bone marrow transplants without rejecting the graft or experiencing graft-versus-host disease. The study suggests a novel approach to preventing and treating this life-threatening reaction, potentially increasing the availability of bone marrow donors.
Researchers at Baylor College of Medicine discovered a common flaw in the dystrophin protein that causes dilated cardiomyopathy, leading to enlarged heart chambers. Using ventricular assist devices can restore the protein's function and improve heart pumping, offering new hope for patients.
New research examines how managed care affects access to alcohol and drug treatment, highlighting the need for clear guidelines and accountability. Studies show that prior authorization requirements can set up barriers to timely treatment and that longer retention rates are associated with more positive outcomes.
A simple immunochromatographic assay detected specific antibodies in the blood of untreated coeliac patients, with high accuracy and speed. The test can be done in a doctor's surgery and is useful for screening patients with untypical symptoms or risk factors for coeliac disease.
The Swedish trials indicate a significant reduction in breast cancer mortality among women given mammography screening, with the greatest benefit seen in age groups 60-69 years. The trials found no significant difference in death from all causes between screening and control groups.
