Disease relevance of Batrachoidiformes

• Gulf toadfish (Opsanus beta) were continuously exposed as embryos, sac fry, and juveniles to technical chlorpyrifos in two 49-day early life-stage toxicity tests [1].
• Renin response to hemorrhage and hypotension in the aglomerular toadfish Opsanus tau [2].

High impact information on Batrachoidiformes

• One species in particular, the gulf toadfish (Opsanus beta), has been shown to rapidly switch from ammonia excretion to urea synthesis and excretion during a variety of stress conditions (including confinement) [3].
• To gain insight into the functional roles of ASIC1, we cloned and examined the properties of the evolutionarily distant species toadfish (Opsanus tau), approximately 420-million year divergent from mammals [4].
• Here we report a phylogenetic analysis of the cytochrome P-450 1A (CYP1A) genes including two new sequences determined from teleost fish, toadfish (Opsanus tau) and scup (Stenotomus chrysops) [5].
• Room temperature radioassay for B12 with oyster toadfish (Opsanus tau) serum as binder [6].
• Effect of the anesthetic tricaine (MS-222) on nerve activity in the anterior lateral line of the oyster toadfish, Opsanus tau [7].

Biological context of Batrachoidiformes

• Unidirectional efflux of Cl was examined in the Gulf toadfish, Opsanus beta, in artificial seawater solutions with modified concentrations of Cl and HCO3 [8].
• 1. The parvalbumin from the very fast striated muscle of the swimbladder of the toadfish (Opsanus tau) has been purified to homogeneity and its amino acid sequence has been completely elucidated [9].

Anatomical context of Batrachoidiformes

• Gamma-aminobutyric acid is present in a spatially discrete subpopulation of hair cells in the crista ampullaris of the toadfish Opsanus tau [10].
• The organization of the central lateral line pathways in the midshipman fish, Porichthys notatus, was identified following biotin injections into physiologically identified sites in the lateral line-recipient nucleus ventrolateralis in the midbrain [11].
• Ultrastructural studies demonstrated significant trafficking of dense-cored vesicles (50-200 nm) between the Golgi apparatus and the apical membrane of epithelial cells surrounding gill filaments and lamellae in these two Opsanus spp [12].
• Among Batrachoidiformes, all known representatives have intrinsic swimbladder muscles that are never associated with the pectoral girdle and are innervated by midline sonic motoneurons [13].
• The organization of the descending and secondary octaval nuclei in the hindbrain of the Gulf toadfish, Opsanus beta, was revealed following the injection of biotin compounds into a physiologically identified auditory region of the torus semicircularis [14].

Associations of Batrachoidiformes with chemical compounds

• Recent neurophysiological evidence in the plainfin midshipman fish (Porichthys notatus) demonstrated that isotocin (IT) and arginine vasotocin (AVT) modulate fictive vocalizations divergently between three reproductive morphs [15].
• Cholinergic neurons in the brain of a teleost fish (Porichthys notatus) located with a monoclonal antibody to choline acetyltransferase [16].
• To provide an anatomical framework for the modulation of vocalization by IT and to foster comparisons with the distributions of the IT homologues mesotocin (MT) and oxytocin (OT) in other vertebrate groups, we describe putative IT distributions in the midshipman and the closely related gulf toadfish, Opsanus beta [15].
• Sex steroid levels in Porichthys notatus, a fish with alternative reproductive tactics, and a review of the hormonal bases for male dimorphism among teleost fishes [17].
• Catecholamines and 5-hydroxytryptamine in photophores of Porichthys notatus. Radioenzymatic detection and radioautographic localization [18].

Gene context of Batrachoidiformes

• Superoxide dismutase, catalase, and glutathione peroxidase in the swim bladder of the physoclistous fish, Opsanus tau L [19].
• Crystal structure study of Opsanus tau parvalbumin by multiwavelength anomalous diffraction [20].
• Induction of carbamoyl phosphate synthetase III and glutamine synthetase mRNA during confinement stress in gulf toadfish (Opsanus beta) [21].
• Dogmas and controversies in the handling of nitrogenous wastes: 5-HT2-like receptors are involved in triggering pulsatile urea excretion in the gulf toadfish, Opsanus beta [22].

Analytical, diagnostic and therapeutic context of Batrachoidiformes

• Pharmacomorphological study of denervation induced by 6-hydroxydopamine in Porichthys photophores [24].
• Photophores of Porichthys notatus were examined by electron-microscopic radioautography following incubation in tritiated noradrenaline ( [3H]NA) or serotonin ( [3H]5-HT) [25].
• Intraperitoneal injections of adrenaline resulted in increased tritiated water efflux rate in the toadfish, Opsanus beta [26].
