Cuticular plasticization in the tick, Amblyomma hebraeum (Acari: Ixodidae): possible roles of monoamines and cuticular pHDownload
Abstract: The degree of plasticization of the alloscutal cuticle of a 'hard' (ixodid) tick, Amblyomma hebraeum, and a 'soft' (argasid) tick, Ornithodoros moubata, was assessed throughout the blood-feeding period. Cuticle viscosity was calculated from rate of creep of cuticle under constant load...
Hypophysiotropic action of pituitary adenylate cyclase activating polypeptide (PACAP) in the goldfish: Immunohistochemical demonstration of PACAP in the pituitary, PACAP stimulation of growth hormone release from pituitary cells, and molecular cloning of goldfish pituitary type I PACAP receptorDownload
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a member of the glucagon/secretin peptide family, and its molecular structure is highly conserved in vertebrates. In this study, the functional role of PACAP in regulating GH release in the goldfish was investigated. Using...
γ-Aminobutyric Acid Up-Regulates the Expression of a Novel Secretogranin-II Messenger Ribonucleic Acid in the Goldfish PituitaryDownload
An RNA-arbitrarily primed PCR differential display strategy was used to identify candidate genes in the pituitary that are up-regulated by endogenously activated g-aminobutyric acid (GABA) systems that may also be involved in the control of reproduction. Goldfish were injected with the GABA...
