Acute and developmental toxicity of metal oxide nanoparticles (ZnO, TiO2, Fe2O3, and CuO) in Xenopus laevis
(2009-05)ZnO, TiO2, Fe2O3, and CuO nanomaterials (20-100 nm) were evaluated to determine toxicity of acute exposure using the Frog Embryo Teratogenesis Assay Xenopus (FETAX) protocol. Acute exposure to the tested metal oxide ... -
An intrinsic CRF signaling pathway in the optic tectum
(2012-08)Corticotropin-releasing factor (CRF) is a 41 amino acid peptide that is best known as the principle hypophysiotropic hormone regulating the pituitary-adrenal axis during stress. CRF also regulates many stressors and anxiety ... -
Genotoxicity in Xenopus laevis exposed to sodium perchlorate and UV radiation
(Texas Tech University, 2004-08)The purpose ofthis work was to determine if simultaneous exposure of amphibian larvae to sodium perchlorate (SP) and UV-B radiation would affect mortality, final stage of development, single strand DNA breaks (SSB), ... -
The role of Cdc6 and geminin in Xenopus laevis oocytes during meiosis
(2009-05)In oocytes three important tasks are accomplished during meiosis: 1) establishment and maintenance of replication competence 2) inhibition of DNA replication between meiosis I (MI) and meiosis II (MII) and 3) proper ... -
The effects of ammonium perchlorate on survival, metamorphosis, and reproduction in the South African clawed frog, Xenopus laevis, and native amphibian populations
(Texas Tech University, 2004-12)Xenopus laevis and native anuran embryos and larvae were exposed to ammonium perchlorate (AP) in a series of experiments. Five- and seventy-day median lethal concentrations (LC50S) for Xenopus laevis embryos were 510 ± 36 ...
