A new study found a link between sleep-disordered breathing (SDB) and Alzheimer's disease risk factors in cognitively normal elderly patients. Lean SDB patients showed biomarkers of AD risk, including increased P-Tau and T-Tau levels, glucose hypometabolism, and hippocampal atrophy.
Researchers have identified a potential new risk factor for obstructive sleep apnea: asthma. The study, which followed 1,500 participants over eight years, found that patients with asthma were 1.70 times more likely to develop sleep apnea. Childhood-onset asthma was associated with an even stronger link to sleep apnea.
Researchers found that purified ginger components can work synergistically with beta-agonists to relax airway smooth muscle and improve breathing. The most effective component was 6-shogaol, which dissolves F-actin filaments and inhibits phosphodiesterase4D.
Scientists at Johns Hopkins Medicine discovered that blocking critical bone regulation protein halts OA progression in mice, suggesting a new therapeutic approach to joint replacement surgery. The theory proposes that initial harm to cartilage causes excessive bone growth, leading to disease exacerbation.
A recent study published in Investigative Genetics found that the genomic diversity of the Dutch population follows a southeast-to-northwest gradient, with the population separated into four geographic groups. The researchers propose that this pattern is due to recent movement within the last 2000 years, rather than ancient events.
Researchers used geological proxies and computer models to understand how sea level affected rainfall patterns in the Indo-Pacific warm pool during the last ice age. The study found that lowered sea levels led to reduced convection over a region of the warm pool, resulting in drier climates in some areas and wetter climates in others.
A new computational method called viSNE enables scientists to analyze high-dimensional cancer data, revealing distinct cell subpopulations and detecting minimal residual disease. This breakthrough technology has the potential to improve cancer diagnosis and treatment.
New research finds that coherent twin boundaries in metals contain tiny kink-like steps and curvatures, making them stronger but also more electrically resistant. This discovery challenges previous understanding of these materials and could lead to improved engineering designs for high-strength applications.
The American Society for Gastrointestinal Endoscopy (ASGE) will honor important contributions to the field of endoscopy during the ninth annual ASGE Crystal Awards on May 19, 2013. The event recognizes leaders, researchers, and educators who have strengthened the specialty and the Society.
A new study published in Nature Geoscience investigates the ability of climate models to simulate tropical climate change by analyzing preserved geological evidence from the Last Glacial Maximum. The research reveals that only one model reproduces the rainfall patterns found from the geological evidence, with implications for simulatin...
A new study projects that heat-related deaths in Manhattan will increase by 20 percent by the 2020s and potentially up to 90 percent or more by the 2080s. Higher winter temperatures may offset some of these deaths, but overall temperature-related mortality is expected to rise.
The AGA recognizes individuals who have made significant contributions to gastroenterology through its esteemed recognition awards. The 2013 awardees include Dr. Chung Owyang, who received the Julius Friedenwald Medal for his lifelong contributions to the field of gastroenterology.
Researchers have identified an immune protein called CD52 that can suppress the immune response and prevent or reverse type 1 diabetes. This discovery has wider implications for treating autoimmune diseases such as multiple sclerosis and rheumatoid arthritis.
Researchers engineered bacteria to produce electricity solely from hydrogen gas and carbon dioxide, enabling the growth of a biorenewable energy source. The breakthrough utilizes Geobacter species, which can transfer electrons over long distances via conductive filaments.
Researchers at Mayo Clinic have developed a promising method to distinguish between pancreatic cancer and chronic pancreatitis. A molecular marker obtained from pancreatic 'juices' can identify almost all cases of pancreatic cancer, with a detection rate of 75%.
Scientists at the University of California, Davis have successfully engineered a strain of photosynthetic cyanobacteria to grow without light. This breakthrough allows for cost-effective and controllable biofuel production in diurnal conditions.
A recent study found that traditional fisheries targeting large predators like cod have declined, while shellfish such as prawns and scallops have increased in value. However, this shift is at risk due to disease, species invasions, and climate change, which threaten the long-term sustainability of these ecosystems.
A study by Georgia Tech researchers reveals that RNA can catalyze single electron transfer in oxygen-free environments with the assistance of iron. This process suggests that complex biochemical transformations may have been possible when life began on Earth, and could even revive a latent function of RNA.
A University of Michigan Health System study found that peripherally inserted central catheters more than double the risk of blood clots in critically ill patients and those with cancer. The device is often used for IV medication delivery and has lower infection risks, but may not be suitable for all patients.
Researchers at the University of Innsbruck and Complutense University of Madrid use a quantum simulator to study quantum mechanical phase transitions in many-body systems. They observe how competition between two processes takes place, leading to fragile long-range correlations between distant particles.
A study found that optimal treatment of sleep apnea with CPAP improves glucose levels and reduces cardiometabolic risk in patients with prediabetes. Insulin sensitivity is also enhanced without affecting insulin secretion.
In a surprise twist, female strawberry poison frogs in Costa Rica prioritize the nearest singing male over physical appearance and vocal quality. The research found that females fail to discriminate between different call rates or frequencies, instead opting for the closest speaker.
