Neuronal nitric oxide inhibition attenuates the protective effect of HBO2 during cyanide poisoning.

Conclusions: The results indicate that a specific nNOS inhibition offsets the ameliorating effect of HBO2 during cerebral CN intoxication. However, other factors might contribute to this neuroprotective effect as well. PMID: 30028920 [PubMed - in process]

(University of Saskatchewan) The origin of an understudied hybrid population of poisonous frogs -- highly endangered colorful animals that live deep in the Colombian jungle -- is the result of natural breeding and not caused by wildlife traffickers moving them, a University of Saskatchewan (USask) study shows.

mans Roelants A wide range of frogs produce skin poisons composed of bioactive peptides for defence against pathogens, parasites and predators. While several frog families have been thoroughly screened for skin-secreted peptides, others, like the Microhylidae, have remained mostly unexplored. Previous studies of microhylids found no evidence of peptide secretion, suggesting that this defence adaptation was evolutionarily lost. We conducted transcriptome analyses of the skins of Phrynomantis bifasciatus and Phrynomantis microps, two African microhylid species long suspected to be poisonous. Our analyses reveal 17 evo...

In the present study, we report a novel observation of the dual effects of ABS ...
