A new volume of research explores the physical processes and interactions of Antarctic sea ice, shedding light on its differences from Arctic sea ice. The study highlights the importance of interdisciplinary approaches to understanding this complex environment, which is sensitive to climate change.
Researchers identified two distinct forms of prostate cancer, with one being more aggressive. The study also found that p27 plays a role in Benign Prostate Hyperplasia (BPH), which is genetically different from prostate cancer and not a precursor to its development.
The University of Kentucky has been awarded a $961,582 grant to establish interactive learning modules on the internet for writing grant proposals. The program will target historically underrepresented institutions and provide training and mentorship to help them develop their research capabilities.
Researchers found that ultraviolet light triggers a harmful chemical reaction in the skin, leading to premature aging and cancer. The study reveals that a natural component of human skin, previously thought to be a 'nature's sunscreen,' actually contributes to skin damage.
The Society of Actuaries symposium explored managed care effectiveness using the Health Plan Employer Data and Information Set (HEDIS) tool, highlighting access as a primary concern for consumers. The discussion also touched on issues with data quality and performance measurement in healthcare.
Researchers found a striking increase in falciparum malaria in northern Honduras, with reported cases rising from 52,110 in 1994 to 75,565 in 1996. The more severe form of the disease accounted for 21% of infected patients, highlighting a significant public health concern.
A comprehensive study of 195 short children found a strong link between shortness and behavioral adjustment problems. Growth hormone treatments improved behavior scores and conduct in many cases, with significant improvements in anxiety, depression, and attention deficit disorders.
Researchers found that inexpensive signs can increase stair use by 4.8-7.2% among different age groups and racial demographics, with significant benefits for Caucasians but little impact on African Americans.
A new study found that a larger angle between an artery and its branching points increases the susceptibility to plaque buildup, leading to cardiovascular disease. Researchers discovered that fluid mechanics plays a crucial role in vessel wall thickening, particularly at lower shear stress areas.
Researchers found that fear campaigns can be effective in motivating action, but only if individuals feel threatened and have clear information about the effectiveness of recommended actions. The study tested the impact of a fear campaign on reducing the risk of genital warts caused by human papilloma virus (HPV) among college women.
Researchers have assembled 20 articles to study interactions at the Antarctic Continental Margin, presenting new techniques and expanding year-round measurements. The volume includes a bathymetric chart of the southern Weddell Sea, providing insights into longer-term cycles.
A 15-year study in over 100 families and 1,000 subjects provides the first reliable evidence of genetic susceptibility to schizophrenia. The study identified a stretch of DNA on chromosome 13 associated with schizophrenia susceptibility.
The new volume of the American Geophysical Union's Antarctic Research Series delves into the complex ecosystems found in Antarctic sea ice. Researchers explore various habitats, including algal biomass, nitrogen metabolism, and numerical ecosystem modeling studies, providing insights into the biodiversity of this unique environment.
Researchers at Ohio State University found that wearing a knee brace after ACL reconstructive surgery may not be necessary for optimal recovery. Patients who wore a brace showed no significant improvement in knee stability compared to those who used an elastic knee bandage, suggesting that braces may be unnecessary.
A new study by geneticists at the University of Georgia shows that female fruit flies who have a choice between mates have offspring that live longer as adults. The research confirms the validity of the 'good genes' model, which proposes that females prefer males with certain traits because they indicate high genetic quality.
The Emory/Atlanta CFAR is a multidisciplinary research center focusing on the prevention and treatment of HIV/AIDS. With a $2.3 million grant, it aims to foster collaboration among diverse HIV/AIDS programs in Atlanta.
A recent study published in Pediatric Emergency Care found that air gun injuries accounted for 87 of the 162 injuries caused by guns during a seven-year period. The research revealed that air gun wounds can be serious and even permanent, with 13 children suffering from visual disabilities.
A research team has identified a gene that causes two forms of muscular dystrophy, a genetic disease characterized by progressive weakness and deterioration of skeletal muscles. The discovery may lead to improved diagnosis and treatment options for patients with these disorders.
Researchers aim to prevent leukemia relapse by educating the immune system using immunotherapy and genetically modified cells. The new technology could eliminate second rounds of chemotherapy, reducing toxicity and hospital stays.
A combination of XPS and XRD techniques reveals complex near-surface structures of oxidized palladium alloys, showing chemically bound water and microcrystals of gold and copper. The research provides new information on the mechanical properties and adherence to dental porcelain.
Researchers found a genetic link to abnormal cholesterol absorption in individuals with sitosterolemia, a rare disease characterized by excessive plant sterol absorption. The study identified a specific gene on chromosome 2p21 that regulates selective cholesterol absorption.
A study published in Nature Medicine suggests that the diabetes drug troglitazone may increase the risk of colon cancer by activating the PPAR receptor, which promotes tumor formation in the colon. The study found that mice treated with troglitazone developed a significantly greater number of colon polyps than those not treated.
A new study finds that workers who have strong support from co-workers and family members are more likely to change their diet. Health promotion programs should target all family members, not just high-risk individuals, to build on foundation of family support.
Researchers have located a gene mutation responsible for nonsyndromic mental retardation (MRX), a condition affecting brain development and causing severe cognitive problems. The PAK-3 gene defect, discovered on the X chromosome, gives insight into how neurons interact in learning and memory.
The device, called a fibrous-bed bioreactor (FBB), allows cells to grow in three dimensions and produces large quantities of Developmental Endothelial Locus-1 Protein (Del-1) for cancer research. The FBB's unique design enables high cell densities, making it suitable for growing replacement human organs.
A study by Stanford University School of Medicine found that individuals dissatisfied with their bodies and those with a history of weight fluctuations face extreme difficulty losing weight. The research suggests that combining diet and exercise is crucial for success, emphasizing the importance of addressing both aspects.
