Both of these performances were much better than previous results, revealing our probe is sensitive and reversible for screening applications.We developed a new procedure for the comprehensive analysis of metabolites and enzymes involved in polyamine metabolism pathways. The procedure utilizes stable isotope-labeled polyamines and directly and precisely determines labeled products from enzymatic reactions by ESI-Q-TOF-MS. The activity of different enzymes could be determined in essentially the same manner by suitably adjusting the reaction conditions for each individual enzyme. We applied the procedure to extracts of regenerating rat liver and analyzed the changes in polyamine-metabolizing enzymes and polyamine contents during recovery from partial hepatectomy. A general outline of polyamine metabolism and information of polyamine dynamics were obtained. This kind of comprehensive information would be valuable in unifying detailed but fragmentary information obtained through conventional analyses focusing on one or a few enzymes and on a limited aspect of polyamine metabolic pathway. Providing early psychosis (EP) individuals with family psychoeducation (FPE) can reduce symptoms and improve clinical outcomes. However, relational memory problems may limit prospective utilization of FPE information. This study examines whether memory for FPE can be improved by testing participants during the initial FPE workshop presentation. Data were obtained from 20 people with EP and 20 demographically matched healthy comparison subjects (HC). During session one, FPE was presented in small group workshops, with half of the information re-studied twice (re-study condition) and the remaining information tested twice using cued recall tasks (retrieval practice condition). One week later (session two), delayed cued recall was tested
