Lupin flour, a common ingredient in some foods, may cause an allergic reaction in people with peanut allergies. Those with peanut allergies are advised to avoid all products containing lupin until further testing can confirm its safety.
A six-month study found that long-acting naltrexone injections reduced heavy drinking within the first month of treatment and maintained this response over time. The medication was associated with significant reductions in alcohol dependence when used in conjunction with counseling sessions.
Researchers will investigate the safety and effectiveness of polyunsaturated fatty acids derived from plants like flaxseed, echium, and borage. The studies aim to prevent and treat inflammatory diseases, with an estimated one in three Americans suffering from such conditions within two decades.
Researchers have discovered that molecular motors dynein and kinesin do not compete for control when moving cellular cargo, but instead cooperate to produce more than 10 times the speed of individual motors. This cooperative behavior allows the cargo to move faster and with greater precision inside the cell.
A new study suggests that up to 40% of the early Earth's atmosphere was composed of hydrogen, creating a more favorable climate for the production of pre-biotic organic compounds. This finding contradicts traditional models and supports the idea that life may have emerged earlier than previously thought.
African Americans with lupus have a higher prevalence of EBV-IgG antibodies and EBV-IgA antibodies, which increases the risk of lupus. Genetic variation in CTLA-4 also affects the immune response to EBV in lupus patients.
Chronic inflammation during dialysis enhances oxidative stress, leading to cardiovascular disease, malnutrition, and poor outcomes. Antioxidant supplementation and ROS modulation are proposed solutions to prevent these complications.
Scripps Research scientists identified that certain tissues are more susceptible to amyloid plaques due to their ability to efficiently release misfolded protein. The study found that cells secreting proteins into these tissues secrete the bad proteins most efficiently, making them a key factor in tissue selectivity.
Researchers found that adolescents averaging five minutes of vigorous physical activity per day were leaner and fitter than their peers. This suggests that general exercise recommendations for adolescents should encourage vigorous physical activity to help them maintain a healthy weight.
Research led by Ohio State University found a mutation in the PTEN gene in three people with autism and large heads, raising concerns about an increased cancer risk. The study suggests that individuals with autism and macrocephaly should be offered genetic counseling and testing for PTEN mutations.
The new technique improves specificity of human estrogen receptor alpha by 100 million times, allowing for targeted activation or deactivation of genes in living systems. This breakthrough could lead to advances in gene therapy, metabolic engineering, and animal disease model studies.
A long-term study found that lack of regular vigorous physical activity was the strongest predictor of functional decline in older adults with arthritis. Engaging in exercise or physical activity can reduce functional deterioration by up to 32 percent, according to researchers.
Researchers found that bacterial lineages can be traced despite widespread gene-swapping, which affects medicine and treatment. The study also identifies common genetic material transmission mechanisms.
Researchers identified a new protein called renalase, which regulates heart rate and blood pressure. Reduced levels of renalase have been linked to increased cardiovascular risk in patients with end-stage kidney disease.
