The in vitro autoradiographic distribution of calcium channel antagonist binding sites for 1,4-dihydropyridine and phenylalkylamine has been investigated in rat, guinea pig and human brain. 1,4-dihydropyridine ([3H] (+) PN200-110) and phenylalkylamine ([3H] (-) D-888) binding sites are identically distributed in the brain of the three mammalian species(More)
Rhodobacter sphaeroides is a photosynthetic bacterium which swims by rotating a single flagellum in one direction, periodically stopping, and reorienting during these stops. Free-swimming R. sphaeroides was examined by both differential interference contrast (DIC) microscopy, which allows the flagella of swimming cells to be seen in vivo, and tracking(More)
