Scientists discover nitric oxide's active regulatory role in responding to tissue oxygen needs, enabling red blood cells to regulate blood flow. The findings explain why certain treatments fail or lead to adverse effects, offering new avenues for treating disorders such as sickle cell disease and pulmonary hypertension.
Researchers found that rats depleted of salt show unusual growth of brain cells, with a 30-35% increase in neuron length and branching. This suggests an ability for neurons to make more connections.
A recent study by Ohio State University researchers found that semiconductor companies can improve their technological performance through outsourcing, but only under specific circumstances. The study identified critical characteristics of the end-product and production process that predict successful outsourcing outcomes.
Scientists have solved the long-standing riddle of how nitroglycerin works by discovering an enzyme called mitochondrial aldehyde dehydrogenase (mALDH) that breaks down the drug. The team found that mALDH causes nitric oxide to be released from nitroglycerin, leading to tolerance in patients.
Researchers analyzed care in US, Australia, Canada, and UK to find similar survival rates for low-birth-weight babies. The US spent more on neonatal intensive care but less on reproductive and prenatal care.
Researchers developed a test to predict which patients with locally advanced breast cancer are likely to respond to chemotherapy, and found it was accurate 100% of the time. The test used radiotracer uptake and washout rates to identify patients who would benefit from specific drugs to boost their response.
A new radiosurgery protocol using the Gamma Knife is being tested to eliminate epileptic seizures in patients with temporal lobe epilepsy. The treatment has shown promising results, with up to 95% effectiveness and significant improvement in quality of life.
Researchers have developed a synthetic guide star system that can correct for atmospheric turbulence in about three fifths of the sky, opening up a much larger portion of the heavens for study. The system uses laser beams to create artificial stars, providing high-quality images of planets, galaxies, and other objects.
MERBoards will provide a new tool to support collaborative processes in Mars Surface Operations, enhancing mission operations with interactive displays and annotation capabilities.
A new journal series aims to educate physicians about individual and systems factors contributing to medical errors. The series analyzes real-life cases, including a study of 17 errors that allowed one patient to receive an invasive procedure intended for another.
A recent study by Ohio State University found that almost one in 13 soft contact lens wearers develop severe corneal abrasions, leading to infections or other problems. The study suggests that optometrists monitor their patients for such abrasions and proper hygiene habits can prevent them.
A study found that RSV prevention in premature infants during their first winter of life can lead to better lung function and fewer respiratory issues. The treatment reduced the risk of RSV infections by 85%, resulting in fewer colds, asthma attacks, and allergies.
A study found that patients who had one-on-one discussions with pharmacists reported using less medication and having fewer medication-related problems. The sessions helped increase communication between patients and their physicians, leading to improved health outcomes.
A new series of articles explores the causes of medical errors, highlighting the limitations of relying solely on patient charts. Increasing the number of reviewers and requiring confidence in negligence can reduce rates of negligent events.
A survey of over 1,750 inner-city teenagers found that education and job opportunities were top priorities for achieving a positive future. The study suggests that focusing on protective factors such as education, jobs, and adult connections can help mitigate the negative effects of urban poverty.
Researchers found that Rockhoppers, the smallest species, swim up to 180 miles or more from their home territory on New Island, putting them at risk of collisions with fishing nets and oil spills. This expansion highlights the need for conservation strategies to reduce conflicts between humans and organisms in the open ocean.
A recent NHLBI-sponsored study found that weight concerns and a drive for thinness significantly increased the risk of teenage girls becoming daily smokers. The study also identified other factors such as stress, poor conduct, and family background that contributed to this risk.
Researchers have developed a new technique that predicts Madden-Julian Oscillations (MJOs), which can provide two-weeks notice for storms. This allows scientists to issue storm warnings weeks earlier than current conventional weather forecasting, supporting sustainable development efforts.
Researchers from Brookhaven National Laboratory found that high concentrations of volatile organic compounds (VOCs) in the Houston Ship Channel region contribute to excessive ozone production. The study's findings may lead to more effective regulations for protecting public health.
A new climate study reveals California's increased risk of warmer temperatures, smaller snowpacks, and altered water supplies due to rising carbon dioxide levels. The research offers precise regional specificity and statistical analysis, providing a more reliable basis for planning climate change mitigation strategies.
Scientists at PNNL and the Institute of Immunological Engineering have created unique humanized antibodies to gamma interferon, a protein that triggers autoimmune conditions. These fully humanized antibodies may provide long-term treatment for autoimmune diseases.
A study of 2,005 well-educated women found that one in 10 reported histories of domestic violence, resulting in significant increases in neurological and gynecological problems. The study highlights the need for healthcare professionals to screen for abuse regardless of socioeconomic status.
Researchers at Brown University have discovered that the Arp2/3 protein complex plays a critical role in regulating the first step of human blood clotting. The complex drives platelets to change shape, forming long arms that grab onto other cells and fibrin, ultimately leading to clot formation.
A new drug could provide a non-destructive way to treat blindness in diabetics, blocking the pathway that causes damage. The drug is currently being tested in clinical trials and has been funded by $4.7 million from the US-based JDRF and NHMRC.
Research suggests preeclampsia is associated with increased risk of preterm delivery and later-life hypertension and cardiovascular disease. Elevated sialic acid levels indicate inflammation and are linked to atherosclerosis, suggesting a potential preventive role for aspirin.
A new study of nearly 10,000 adolescents found that children's psychological well-being improves three years before and after a parents' marriage ends, but their test scores remain lower. The researchers suggest that cumulative academic performance contributes to the persistent decline in test scores.
Researchers found that cocaine elevates body temperature by impairing the body's ability to increase skin-blood flow, sweat, and perceive excessive heat stress. Cocaine abuse in hot temperatures increases the risk of serious heat-related injuries, including heat stroke and death.
