Soil bacterial composition is used as one of the important indicators of negative effects of the use of pesticides in agriculture. Very little is known on the effects of fungicides, particularly carbendazim and pencycuron on soil bacterial community. In this study, laboratory experiments were conducted to examine the effects of various concentrations of(More)
BACKGROUND/PURPOSE Neuropsychologic deficits are prevalent among schizophrenic patients and are closely associated with pathogenesis and outcome. The pattern, extent, severity and contributing factors to such deficits remain to be examined in Taiwanese schizophrenic patients. METHODS A total of 122 schizophrenic patients and 94 healthy subjects for(More)
The total haemocyte count (THC), differential haemocyte count (DHC), phenoloxidase activity, respiratory bursts (release of superoxide anion), superoxide dismutase activity, and phagocytic activity and clearance efficiency to the pathogen Vibrio alginolyticus were measured when white shrimp, Litopenaeus vannamei, (7.5 ± 0.5 g) were individually injected(More)
Because of the growing concern over highly contaminated crystal violet (CV) wastewater, an FeGAC/H(2)O(2) process was employed in this research to treat CV-contaminated wastewater. The experimental results indicated that the presence of iron oxide-coated granular activated carbon (FeGAC) greatly improved the oxidative ability of H(2)O(2) for the removal of(More)
The composition of culture-independent microbial communities and the change of nitrogenase activities under the application of butachlor in paddy soil were investigated. Nitrogen-fixation ability was expressed by the amount of acetylene reduction, and changes of microbial communities were studied by using denaturing gradient gel electrophoresis (DGGE)(More)
