Researchers have shown that gene therapy can induce the formation of extra sensory hair cells in young mice, but this approach has limitations in older animals. Introducing a specific gene called Atoh1 into the cochleae of young mice can produce electrical signals and connect with neurons.
A randomized trial found that highly targeted irradiation had equally good results as whole breast radiotherapy in early stage cancer, with a lower risk of adverse effects. The treatment reduced the rate of local recurrence by 0.8% and improved cosmetic outcomes by 18%, making it a potential game-changer for breast cancer patients.
A recent study published in PLOS ONE found that male adolescents have bacteria in their urinary tracts, which are similar to those found in young women. The researchers discovered that the types of bacteria on the penis differ from those in the urethra and that circumcision status affects bacterial composition.
A two-year study found that a high-fat diet improved glycaemic control and increased 'good' cholesterol in patients with Type 2 diabetes. The low-carbohydrate group experienced significant weight loss and reduced blood sugar levels, while the low-fat group showed minimal improvements despite similar weight loss.
A lack of basic evidence is hindering the prevention of sudden heart attacks in sports, with a need to track all incidents like Fabrice Muamba's on-pitch collapse. Reliable data collection and cooperation among sporting organisations are essential to mitigate risks and improve understanding of the condition.
A Penn study found that more than 75% of cardiac arrests occur outside the range of nearby automated external defibrillators (AEDs), highlighting the need for strategic placement and easy location. The study suggests innovative ways to help the public find AEDs in emergencies.
Researchers found that vitamin K2 can restore energy production in defective mitochondria, similar to those found in Parkinson's patients. This discovery offers potential treatment options for patients with the disease.
A Georgetown University Medical Center study found that phenobarbital stunts neuronal growth, leading to cognitive abnormalities in rats. The researchers suggest that anti-epilepsy drugs may not be as benign as thought and could have long-lasting impacts on brain function.
A UNC-led team discovers that lung cancer molecular subtypes correlate with distinct genetic alterations and patient response to therapy. The study refines their previous report on three molecular subtypes of non-small cell lung cancer, suggesting new avenues for targeted treatment.
Researchers found regional heart failure readmission rates vary widely due to availability of care and socioeconomics. Communities with higher rates have more physicians, hospital beds, and sicker populations, leading to increased readmissions among the elderly and poor.
Researchers at Rutgers University have discovered a new way to stimulate the activity of immune cell opiate receptors, leading to efficient tumor cell clearance. The study builds upon previous research showing that replenishing endorphins can prevent stress and immune problems in fetal alcohol-exposed test subjects.
A $373,256 grant will be used to re-curate and modernize the West Virginia Biological Survey Museum, which houses over 21,000 specimens. The project aims to preserve the nation's largest museum collection of mammals, amphibians, and reptiles from West Virginia.
A new maintenance therapy, lenalidomide, has been shown to improve outcomes for patients with newly diagnosed multiple myeloma who have undergone a stem cell transplant. The study found that patients treated with lenalidomide had a 59% chance of surviving free of disease progression after three years.
Researchers found a correlation between bed shortages and higher readmission rates, suggesting patients were discharged too early. The study recommends better planning and logistical solutions to prevent these problems.
Dr. Gregor Reid and his team will study the impact of probiotic yogurt on pregnant women and their children in Tanzania to investigate potential benefits for disease prevention. The project aims to understand how nutrition and bacteria can be passed from mothers to their children, a critical period for health development.
Researchers at Virginia Commonwealth University found that mild TBI can cause structural disruption of axons and alter neuronal firing patterns. This discovery advances research on posttraumatic disorders and enables better understanding of long-lasting neurological issues following a head injury.
The loss of elephants and rhinoceroses in tropical forests puts structural integrity at risk, while Asian tapirs are found inadequate for seed dispersal. The study highlights the importance of protecting megafauna and reintroducing them into areas where they have disappeared.
A groundbreaking study on manta ray migration patterns reveals feeding habitats and threats to the world's largest ray. The research found that manta rays spend most of their time in coastal areas with abundant zooplankton and fish eggs, but only 11.5% of locations occurred within marine protected areas.
Researchers are conducting two clinical trials to test the effectiveness of vitamin D and Imatinib in reducing asthma symptoms. Participants with mild to moderate asthma will receive vitamin D, while those with hard-to-control asthma will receive Imatinib.
A novel ambulatory cardiac monitor, Zio Patch, has been found to be effective in diagnosing irregular heart rhythms and preventing unnecessary follow-up care. The study showed that 59% of symptomatic patients did not have arrhythmia and may not require further work-up.
A study by UCI anthropologist Leo Chavez details experiences of young undocumented immigrants, finding they often become involved in campaigns to change the law due to societal perception as disposable. The study found that these individuals face social constraints, limited economic opportunities and lower levels of education compared ...
