Density functional calculations have been performed on a cyclohexadienol endoperoxide model system derived from the tyrosine model compound p-cresol and singlet molecular oxygen. Results indicate that the endoperoxide undergoes a 1,3 hydrogen migration to form a cyclohexadienone hydroperoxide.

Bioprotective properties of Turmeric An investigation of the antioxidant and antimicrobial activities

Food-borne bacterial infections pose a significant risk for human populations. The increasing occurrence of antibiotic resistance in bacterial strains has heightened this risk further. This circumstance has led to a renewed interest in traditional treatments for infections. This investigation focused on the bio-protective properties of turmeric, which is a spice that is used in India for extensive medicinal and culinary purposes.

Examining morphological characteristics of triggerfish: a three-dimensional reconstruction of skeletal and muscular features of Rhinecanthus rectangulus.

Examining morphological characteristics of triggerfish: a three-dimensional reconstruction of skeletal and muscular features of Rhinecanthus rectangulus.

Triggerfishes (family Balistidae) are members of one of the most derived group of fishes, the Tetraodontiformes. Species of this family employ a median paired fin (MPF) swimming style that recruits the use of the dorsal and anal fins for propulsion. This study used ultra-thin slice plastination to investigate median fin myology of Rhinecanthus rectangulus, a common triggerfish within the Indo-Pacific region. This method maintained detail and accurate spatial relationships between anatomical features, allowing accurate rendering of the vertebral column, four sets of pterygiophores, one myotome, and two sets of muscle groups along the median fins.

Mind over matter: how to think yourself healthy

Mind over matter: how to think yourself healthy

Kevin J. Tracey, MD, may have discovered the reason why Buddhist and Hindu monks tend to live longer and healthier lives. He recently spoke at a conference co-hosted by the Columbia University Integrative Medicine Program and Tibet House, discussing how advances in western medicine might explain what has been, until now, a mystical and religious phenomenon. The guest of honor at the conference was the Dalai Lama himself, who has been very cooperative in allowing the study of his religious followers for medical purposes.
