Fipronil: mechanisms of action on various organisms and future relevance for animal models studies
Because insects had developed resistance to several insecticides, today, neonicotinoids and fiproles are used to combat pests. The difference between this two classes of insecticides is that fipronil acts by inhibiting the receptors of nervous cells, while neonicotinoids perturbs the neuronal transmission. The suitable properties of fipronil make that its use to be more obvious on the pesticide...
متن کاملStudies on Enzyme Action
The hydrolyzing actions of various preparations of the adult eel were studied on ten esters in the usual way. The results are presented in the form of curves for the relative actions and in a table for the absolute actions obtained in one complete experiment. The separation of the enzyme material in some cases into an active portion and a co-enzyme, the mixture showing greater actions on some e...
متن کاملAsymmetry and enzyme action.
It must, I think, be rare to be rewarded so generously for work that was so purely a pleasure in planning and execution. I shall try, in return, to impart some of that pleasure today. In 1948, a short but historic note by Alexander Ogston appeared in the scientific magazine Nature, demonstrating the importance of a particular type of stereochemical thinking in relation to biochemical processes ...

متن کاملThe mutagenic action of caffeine in higher organisms.
Caffeine is a purine, l, 3, 7-trimethyl xanthine. Since it is consumed in great quantities by man, the question concerning whether it is a mutagen for man is of great significance. There is now good evidence that caffeine is mutagenic not only in bacteria (4, 5, 7, 9,18), fungi (6,41), and plants (11, 12), but equally mutagenic in Drosophila melanogaster [2, 16, 25, 29; negative reports, (40)],...
