Challenges and regulations associated with handling fish during fisheries management activities have increased efforts to achieve U.S. Food and Drug Administration approval for an immediate-release sedative for fish. The objectives of this study were to (1) identify the target concentration of AQUI-S 20E for sedation of Pallid Sturgeon Scaphirhynchus albus to a handleable state followed by rapi...

—Pharmacological ?1 anesthetics are used frequently in aquatic animal husbandry and research. Although several studies have investigated the effects of these anesthetic agents on immune responses in fish, none have assessed such effects in amphibians. To address this disparity, we exposed Osteopilus septentrionalis tadpoles to 0.005% benzocaine, 0.1% tricaine mehanesulphonate (MS-222), or artif...

The Anthropocene is characterised by the unparalleled human-mediated passage of organisms from their natural ranges to ecosystems across world (Capinha et al., 2015; Ricciardi, 2007). If these non-native manage disperse initial introduction point and seed new populations in range, they are regarded as invasive (Blackburn 2011; Richardson 2011). This reshuffling world's biota a decisive agent gl...

The compounds CGP7930 [2,6-Di-tert-butyl-4-(3-hydroxy-2,2dimethyl-propyl)-phenol] and its close analog CGP13501 were identified as positive modulators of -aminobutyric acidB (GABAB) receptor function. They potentiate GABA-stimulated guanosine 5 -O-(3-[S]thiotriphosphate) (GTP [S]) binding to membranes from a GABAB(1b/2) expressing Chinese hamster ovary (CHO) cell line at low micromolar concentr...
