Evaluation of the Pseudalert/Quanti-Tray MPN Test for the Rapid Enumeration of Pseudomonas aeruginosa in Swimming Pool and Spa Pool Waters.

This study assessed the performance of a new most probable number test (Pseudalert/Quanti-Tray) for the enumeration of Pseudomonas aeruginosa from swimming pool and spa pool waters by comparing it to the international and national membrane filtration-based culture methods for P. aeruginosa: ISO 16266:2006 and UK The Microbiology of Drinking Water-Part 8 (MoDW Part 8) which both use Pseudomonas CN agar. The comparison was based on the calculation of mean relative differences between the two methods conducted according to ISO 17994:2014.

Synthesis and pharmacological evaluation of CNS activities of [1,2,3]triazolo[4,5-b][1,5]-, imidazolo[4,5-b][1,5]-, and pyrido[2,3-b][1,5]benzodiazepines. 10-Piperazinyl-4H-1,2,3-triazolo[4,5-b][1,5]benzodiazepines with neuroleptic activity.

The synthesis of [1,2,3]triazolo[4,5-b][1,5]-, imidazolo[4,5-b][1,5]-, and pyrido[2,3-b][1,5]benzodiazepines is described. The antidopaminergic and anticholinergic activities of the compounds have been examined by the respective in vitro [3H]spiperone and [3H]QNB receptor binding assay. The neuroleptic potential has been further evaluated in terms of their ability to produce hypothermia and catalepsy in mice and a conditioned avoidance response in rats.

10-Piperazinyl-4H-theino[3,2-b][1,5]- and -[3,4-b][1,5]benzodiazepines as potential neuroleptics.

The synthesis of 10-piperazinyl-4H-thieno[3,2-b][1,5]benzodiazepines is described. The activity of these compounds has been assessed on the basis of their ability to produce hypothermia in mice and block a conditioned avoidance response (CAR) and produce catalepsy in rats, and the results are compared with various classical and nonclassical neuroleptic drugs. A number of compounds (6, 17, 21, and 22) demonstrate potency greater than clozapine and also show low degree of catalepsy.
