BACKGROUND When H-reflexes are recorded during movement in human subjects, the stimulator current output is not a good indicator of sensory stimulation efficacy because of unavoidable nerve movement relative to the stimulus electrodes. Therefore, the M-wave amplitude has been used by researchers as an indicator of the efficacy of the stimulus. In this study(More)
Longitudinal measurements of dopamine (DA) uptake and turnover in transgenic rodents may be critical when developing disease-modifying therapies for Parkinson's disease (PD). We demonstrate methodology for such measurements using [(18)F]fluoro-3,4-dihydroxyphenyl-L-alanine ([(18)F]FDOPA) positron emission tomography (PET). The method was applied to(More)
BACKGROUND A major risk-factor for developing Parkinson's disease (PD) is genetic variability in leucine-rich repeat kinase 2 (LRRK2), most notably the p.G2019S mutation. Examination of the effects of this mutation is necessary to determine the etiology of PD and to guide therapeutic development. OBJECTIVE Assess the behavioral consequences of LRRK2(More)
Water deprived rats were trained to drink from a water spout within an apparatus on each of 2 days. On the third day, passive avoidance of the spout was induced by giving the animal a 0.3 sec, 5 mA footshock after 1 lick at the spout. A test for retention of the avoidance learning was given 48 hr following training. ECS administered through cortical(More)
The trial was carried out at a commercial pig farm in Bukit Pelanduk, Negeri Sembilan, Malaysia. The objective of the study was to assess the efficacy of supplemental iron in drinking water and iron in paste form in comparison with the iron dextran injection. A total of 12 litters were used divided into three treatments : iron dextran injection (ID),(More)
