O-16: Metabolism of Exogenous Fatty Acids, Fatty Acid-Mediated Cholesterol Efflux, PKA and PKC Pathways in Boar Sperm Acrosome Reaction
Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
متن کاملAbundances of the elements: Meteoritic and solar
New abundance tables have been compiled for Cl chondrites and the solar photosphere and corona, based on a critical review of the literature to mid-1988. The meteorite data are generally accurate to +5-10%. Significant discrepancies between Sun and meteorites occur only for Fe, Mn, Ge, Pb, and W; other well-determined elements agree to &90/o on the average. There is no evidence for group fracti...
متن کاملRacemization of Meteoritic Amino Acids
Meteorites may have contributed amino acids to the prebiotic Earth, affecting the global ratio of right-handed to left-handed (D/ L) molecules. We calculate D/ L ratios for seven biological, α-hydrogen, protein amino acids over a variety of plausible parent body thermal histories, based on meteorite evidence and asteroid modeling. We show that amino acids in meteorites do not necessarily underg...
متن کاملDetermination of Tocopherols and Fatty Acids in Seeds of
Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil . Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...
متن کاملGCR Neon Isotopic Abundances: Comparison with Wolf-Rayet Star Models and Meteoritic Abundances
Measurements of the neon isotopic abundances from the ACE-CRIS experiment are presented. These abundances have been obtained in seven energy intervals over the energy range of ~80<E<280 MeV/nucleon. The Ne/Ne source ratio is derived using the measured Ne/Ne abundance as a "tracer" of secondary production of the neon isotopes. We find that the Ne/Ne abundance ratio at the cosmic-ray source is a ...
