Asteltoxins belong to a group of polyene pyrone mycotoxins that are known be potent inhibitors mitochondrial ATP synthesis and hydrolysis. Asteltoxin A was first isolated from the toxic maize cultures Aspergillus stellatus. Several attempts have been made synthesize asteltoxin A, starting with bis(tetrahydrofuran) moiety has demonstrated previously in biosynthetic studies. This review highlight...

tio 2 nanoparticles (nps) might be considered as the most important photosensitizer due to high photocatalytic and sonocatalytic efficiency, low toxicity, excellent biocompatibility, low cost and high chemical stability. tio 2 -nps normally tend to aggregate in physiological medium and which results to decreased cell viability and inducing expression of stress-related genes. thus dispersion and...

Biological studies of the relationships between the schizoaffective disorders, the affective disorders, and schizophrenia suggest that no simple reductionist model is supported by currently available data. Thus, both affective and schizoaffective patients but not schizophrenics, manifest abnormalities such as decreased platelet serotonin (5-HT) uptake, blunted clonidine-induced increase in seru...

The taxonomic nomenclature of Stelling-Dekker (1931) and Lodder (1934) is used throughout the paper. The yeast strains were derived partly from the stock of the Department of Bacteriology and Hygiene of the Hebrew University and partly from the following type culture collections: National Type Culture Collection, London; American Type Culture Collection, Washington; and the Centraalbureau voor ...
