Selenium (Se) is a trace element that is essential for health. Organic Se created by Se-enriched microorganisms has the characteristics of low toxicity, high bioavailability, and regulation of physiological functions. Here, the regulatory effect of Se-enriched Aspergillus oryzae A02 on the reproductive function of male mice and its potential molecular mechanism was studied.

Article Synopsis
  • * Biological tests demonstrated that the extract can reduce venom-induced neuromuscular blockade when applied before exposure, but not after, suggesting timing is crucial for effectiveness.
  • * While quinine was not found in the extract, the presence of coumarin derivatives and other unknown alkaloids may contribute to the extract's ability to mitigate the effects of the venom.

November 2024

Key Laboratory of Environmental Medicine Engineering of Ministry of Education, Medical School, Southeast University, Nanjing, China; Shenzhen Ruipuxun Academy for Stem Cell & Regenerative Medicine, Shenzhen, China. Electronic address:

In Caenorhabditis elegans, 6-PPD quinine (6-PPDQ) could cause several aspects of toxicity together with alteration in glucose metabolism. However, transgenerational alteration in glucose metabolism remains still unknown after 6-PPDQ exposure. In the current study, we further observed transgenerational increase in glucose content induced by 6-PPDQ (1-10 μg/L).

Arbuzov Institute of Organic and Physical Chemistry, FRC Kazan Scientific Center, Russian Academy of Sciences, Akad. Arbuzov st. 8, 420088 Kazan, Russia.

A series of new isatin-3-hydrazones bearing different ammonium fragments was synthesized by a simple and easy work-up reaction of Girard's reagents analogs with 1-(3,5-di--butyl-4-hydroxybenzyl)isatin. All derivatives have been shown to have antioxidant properties. In terms of bactericidal activity against gram-positive bacteria, including methicillin-resistant strains of , the best compounds are , , and , bearing octyl, acetal, and brucine ammonium centers, respectively.
