...by mixing microcapsules of different sizes, we can generate a constant rate of release over a relatively long period of time.The researchers demonstrated their constant-release kinetics with both a model drug compound (rhodamine B) and with piroxicam, a non-steroidal anti-inflammatory drug commonly used to tr...Enzyme halts muscle waste in mouse models of most-common childhood muscular dystrophy
...GalNAc transferase acts as a chemical stimulant to generate scaffold-like tissue at the neuromuscular junction. In research reported earlier this year in the journal Developmental Biology (242, 58-73), Martin and his team described the role of CT GalNAc transferase and their development of mice (called CT mi...Testosterone may reduce risk of stroke in men; Estrogen levels not related to stroke
