Amphibian oocyte maturation and protein synthesis: related inhibition by cyclic AMP, theophylline, and papaverine
(1978)
Two inhibitors of cyclic AMP phosphodiesterase (3':5'-cyclic-AMP 5'-nucleotidohydrolase, EC 3.1.4.17), theophylline and papaverine, inhibit the maturation of Xenopus laevis oocytes induced by 4 different stimuli: human ...
Hypoxanthine transport in the guinea pig and human placenta is a carrier-mediated process that does not involve nucleoside transporters
(1994)
OBJECTIVE: The purpose of this study was to characterize the mechanisms involved in the placental
clearance of hypoxanthine.
STUDY DESIGN: Uptake of isotope-labeled compounds was measured in the in situ perfused guinea ...
