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.
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.
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.
