Rhipicephalus (Boophilus) microplus cDNAs, BmAChE1, BmAChE2, and BmAChE3, were previously identified as presumptively encoding acetylcholinesterases (AChEs), but biochemical identity was confirmed only for recombinant BmAChE3. In the present study, four recombinant BmAChE1 constructs and single recombinant constructs of BmAChE2 and

This work was aimed to determine if 1,5-bis(4-allyldimethylammoniumphenyl)pentan-3-one dibromide (BW284c51), the most selective acetylcholinesterase inhibitor (AchEI), affects the nicotinic acetylcholine (Ach) receptor (AchR) function. Purified Torpedo nicotinic AchRs were injected into Xenopus laevis oocytes and BW284c51 effects on Ach- and
Organophosphorus (OP) pesticides elicit acute toxicity by inhibiting acetylcholinesterase (AChE), the enzyme responsible for inactivating acetylcholine (ACh) at cholinergic synapses. A number of OP toxicants have also been reported to interact directly with muscarinic receptors, in particular the M(2) muscarinic
Insecticides are a potential hazard for non-target organisms like fish particularly at run off events. The study of effects to embryos of the zebra fish Danio rerio is already an accepted tool in waste water monitoring, but effects of various
Comparative biochemistry and physiology. Part B, Biochemistry & molecular biology, 147(2), 340-346 (2007-03-10)
To validate cholinesterase activity as a biomarker of pesticide exposure, we characterized the tissue distribution (whole body, nervous tissue and crop/gizzard), activity at two seasons of cholinesterase in six different species of earthworms collected in an unpolluted field: Lumbricus terrestris
