Several derivatives aminopyrazoles, which are a new class of synthetic insecticide agents, have shown biological activity against lepidopteran, such as Spodoptera frugiperda. The aim of this work was to assess the biological ...

This study was performed to determine the effects of gamma irradiation on UV spectrum on maca, total content of polyphenols, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activities and in vivo biological activities ...

Most neurodegenerative diseases involve the accumulation of misfolded proteins in the nervous system. Impairment of protein degradation pathways such as autophagy is emerging as a consistent and transversal pathological ...

The distribution of 5'-nucleotidase activity in pre-implantation mouse embryos is studied by means of a cytochemical method adapted from Uusitalo & Karnovsky (1977). The enzyme activity is detected from the 4-cell stage ...

Because IGF- lisa natural cardioprotective which migh; improve cardiac function and stimulates growth and proliferation of carfiac myocytes, there is considerable interest to elucidate the molecular f!iechanisms by which ...

The onset of acid and alkaline phosphatase activity is determined by means of Burstone's azo dye coupling methods in oocytes and embryos of the mouse, rat and hamster, and in mouse embryos cultured in vitro. Acid phosphatase ...

An adenylate cyclase activity was identified and characterized in preparations from Xenopus laevis ovarian tissue and follicles. The enzyme is more active in the presence of Mn2+ than of Mg2+, and it is highly activated ...
