Interaction of the pyrethroid insecticides tetramethrin and cypermethrin with enteric cholinergic transmission in the guinea-pig
No full textIn electrically-stimulated longitudinal muscle-myenteric plexus preparations of the guinea-pig ileum, the Type I pyrethroid insecticide tetramethrin (1-100 microM) caused a biphasic response consisting of an early transient increase followed by a sustained decrease in the amplitude of cholinergic contractions. The cholinergic potentiation was antagonized by phenytoin (3 microM), which also prevented the increase in twitch height caused by veratridine (30 nM). The late inhibitory effect of tetramethrin probably involved a direct action on the musculature since contractile responses to applied acetylcholine (100 nM) or histamine (300 nM) were also depressed by this compound. Cypermethrin (1-100 microM), a Type II pyrethroid, had only a minor enhancing effect on electrically evoked contractions. Cypermethrin (30, 60 microM), but not tetramethrin, antagonized the cholinergic response induced by the GABA-A receptor agonist 3-aminopropane sulphonic acid (1-100 microM). These results suggest that neural Na+ channels activation may underlie pyrethroid-induced potentiation of enteric cholinergic transmission. In small intestine, however, cypermethrin is also effective as a noncompetitive antagonist of GABA-A receptor mediated cholinergic contractions

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
