A study by Texas AgriLife Research has linked gene PFKFB3 to metabolic inflammation that leads to diabetes. The researchers believe that a focus on nutrition can prevent or reverse the disease by activating the gene.
A study by Spanish researchers found that roe of hake, lumpsucker and salmon contains high levels of omega-3 fatty acids, essential for metabolic functions. Minimal consumption satisfies the body's requirements, preventing cardiovascular disease and other conditions.
Emerging research reveals that post-menopausal women experience adverse changes in lipid profiles around the time of their final menstrual period, independent of age. Conversely, quitting smoking before or after a heart attack significantly improves long-term survival rates, with reductions comparable to those from lifestyle changes an...
A modified blood adult stem-cell transplant regimen has effectively reversed sickle cell disease in 9 of 10 adults with severe symptoms. The trial's results show that the treatment reduced toxicity and allowed patients to achieve stable mixed donor chimerism, completely replacing their disease-causing cells.
The USDA Forest Service has developed an early warning system to monitor forest health using satellite imagery and land surface phenology data. The system aims to provide near-real-time information on forest conditions impacted by insects, diseases, wildfires, or extreme weather events.
Researchers at the University of Iowa have found a new inherited retinal disease affecting the macula, which is an area critical for central vision. The disease causes abnormal blood vessels to form, leading to swelling or scars that can blur parts of the visual field.
A Kaiser Permanente study of 16,000 women in Hawaii found that Korean-American and Chinese-American women are at one-third higher risk for gestational diabetes. Pacific Islanders, Filipinos, and Puerto Ricans also face a higher risk compared to Caucasian and African-American women.
Cyclone Cleo's rainfall has significantly diminished over the last 24 hours, with its maximum sustained winds down to 40 mph. The storm is expected to dissipate in the next day or two due to wind shear and dry air.
Researchers at the University of Montreal identified a novel molecular mechanism that prevents cancer by regulating the p53 gene. The SOCS1 molecule plays a crucial role in suppressing cancer-causing cytokine activity, offering potential new treatments for chronic inflammatory diseases and cancer prevention strategies.
Researchers found that combining targeted therapies lapatinib and trastuzumab significantly extends survival in HER2-positive breast cancer patients, with a median overall survival of 60.7 weeks compared to 41.4 weeks alone.
