In this work, the mechanisms responsible for dopamine (DA) release impairments observed previously in Huntington's disease model R6/2 mice were evaluated. Voltammetrically measured DA release evoked in striatal brain slices from 12-week old R6/2 mice by a single electrical stimulus pulse was only 19% of wild-type (WT) control mice.

The actions of the protonophore CCCP on intracellular Ca2+ regulation and exocytosis in chromaffin cells have been examined. Simultaneous fura-2 imaging and amperometry reveal that exposure to CCCP not only perturbs mitochondrial function but that it also alters vesicular storage of Ca2+ and catecholamines. By disrupting the pH gradient of the secretory(More)
A direct data link between a CT scanner and a radiation treatment planning system has been developed. The link transmits the data serially over a coaxial cable using the pseudo-paper-tape punch and reader (serial PIO) interfaces. The data transmission rate with error-check is approximately 25,000 8-bit bytes/s. This translates to about 7 s for transferring(More)
