Nuclear anomalies, detected in the cells of the oral cavity mucous membrane, were described. The studies, devoted to analysis of the influence of the method of micronucleus test conduction (coloration, scrape capture) on its results, were summarized. Modern ideas about the factors of different etiology that induce the origin of nucleus aberrations (sex, age, genotype, psychophysiological characteristics, immune status, diseases of different etiology, anthropogenic pollution of the environment, climatic and geographical conditions, ionizing and nonionizing radiations, chemical compounds (medical preparations, biologically active

Problems and unresolved issues associated with peculiarities of micronucleus test usage were emphasized.”
“Deletion of any of the core enzymes of the photorespiratory cycle, one of the

major pathways of plant primary metabolism, results in severe air-sensitivity of the respective mutants. The peroxisomal enzyme hydroxypyruvate reductase ( HPR1) represents the only exception to this rule. This indicates the presence of extraperoxisomal reactions of photorespiratory hydroxypyruvate metabolism. We have identified a second hydroxypyruvate reductase, HPR2, and present genetic and biochemical evidence that the enzyme provides a cytosolic bypass to the photorespiratory core LY2835219 cycle in Arabidopsis thaliana. Deletion of HPR2 results in elevated levels of hydroxypyruvate and other metabolites in leaves. Photosynthetic gas exchange is slightly find more altered, especially under long-day conditions. Otherwise, the mutant closely resembles wild-type plants. The combined deletion of both HPR1 and HPR2, however, results in distinct air-sensitivity and a dramatic reduction in photosynthetic performance. These results suggest that photorespiratory

metabolism is not confined to chloroplasts, peroxisomes, and mitochondria but also extends to the cytosol. The extent to which cytosolic reactions contribute to the operation of the photorespiratory cycle in varying natural environments is not yet known, but it might be dynamically regulated by the availability of NADH in the context of peroxisomal redox homeostasis.”
“Background/Purpose: To study the outcome of a group of patients with schizophrenia receiving community home care case management programs by delineating the relationship among their psychopathology, rehospitalization rates and health-related quality of life (HRQoL).\n\nMethods: This is a cross-sectional study on HRQoL, functioning and associating factors and a retrospectivehistorical control study by comparing the frequency and duration of rehospitalization in a sample of 60 patients with schizophrenia under nonintensive case management (non-ICM) in Taiwan.
