Effects of o,p'-DDE on the immune system of juvenile chinook salmon (Oncorhynchus tshawytscha)

Creator:: Milston, Ruth Helen
Abstract:: Environmental factors such as chemical contamination can have immunomodulatory effects on the immune response of fish and may be contributing to the decline in salmonid populations by augmenting disease susceptibility. Xenobiotics can interfere with the immune system at several levels of complexity, and different immune cells and processes have variable...

Species complexes and phylogenetic lineages of Hoferellus (Myxozoa, Cnidaria) including revision of the genus: A problematic case for taxonomy

Creator:: Alama-Bermejo, Gema, Jirků, Miloslav, Kodádková, Alena, Pecková, Hana, Fiala, Ivan, and Holzer, Astrid S.
Abstract:: Background: Myxozoans are metazoan parasites whose traditional spore morphology-based taxonomy conflicts DNA based phylogenies. Freshwater species of the genus Hoferellus are parasites of the excretory system, with several members infecting food and ornamental fish species, as well as amphibians. This study aims to increase our understanding of their molecular diversity...

Wave-current interaction induced by standing long waves in the surf zone

Creator:: Phaksopa, Jitraporn
Abstract:: This dissertation has focused on the charateristics of bubbles generated by breaking waves and the feedback of wave-current interaction on the forcing mechanism of low frequency wave especially basin seiching wave. For the first study, Optical image capture observations of breaking waves in a laboratory surf zone are presented. The...

Waves on unsteady currents

Creator:: Haller, Merrick C. and Özkan-Haller, H. Tuba
Abstract:: Models for surface gravity wave propagation in the presence of currents often assume the current field to be quasi-stationary, which implies that the absolute wave frequency is time invariant. However, in the presence of unsteady currents or time-varying water depth, linear wave theory predicts a time variation of the absolute...

The effects of taurolidine alone and in combination with doxorubicin or carboplatin in canine osteosarcoma in vitro

Creator:: Marley, Kevin, Helfand, Stuart C., Edris, Wade A., Mata, John E., Gitelman, Alix I., Medlock, Jan, and Seguin, Bernard
Abstract:: Background: Osteosarcoma (OS) affects over 8000 dogs/year in the United States. The disease usually arises in the appendicular skeleton and metastasizes to the lung. Dogs with localized appendicular disease benefit from limb amputation and chemotherapy but most die within 6–12 months despite these treatments. Taurolidine, a derivative of taurine, has...

Temporal Gene Expression Variation Associated with Eyespot Size Plasticity in Bicyclus anynana

Creator:: Oliver, Jeffrey C., Ramos, Diane, Prudic, Kathleen L., and Monteiro, Antónia
Abstract:: Seasonal polyphenism demonstrates an organism's ability to respond to predictable environmental variation with alternative phenotypes, each presumably better suited to its respective environment. However, the molecular mechanisms linking environmental variation to alternative phenotypes via shifts in development remain relatively unknown. Here we investigate temporal gene expression variation in the seasonally...

The gene-ecology of Crepis nana Richardson and Crepis elegans Hooker in Arctic and Alpine North America

Creator:: Legge, Allan Herbert, 1942-
Abstract:: A gene-ecological transplant study was made on populations of the Crepis nana and C. elegans complex from the Arctic and Alpine of North America. Transplants were collected from the Brooks Range, Eagle Summit, and Alaska Range in Alaska, the Rocky Mountains in Alberta, the Olympic Mountains in Washington, the Wallowa...

Inactivation of Clostridium perfringens in Meat Products

Creator:: Alnoman, Maryam M.
Abstract:: Clostridium perfringens type A strains are one of the main causative agents of gastrointestinal (GI) diseases in human and can cause both food poisoning (FP) and non-food-borne (NFB) diseases. Several factors contribute to the pathogenesis of C. perfringens type A strains including the wide presence of C. perfringens spores with...

A taxonomic revision of Astragalus mokiacensis and allied taxa within the Astragalus lentiginosus complex of Section Diphysi

Creator:: Alexander, J. Andrew
Abstract:: North America, with over 400 species of Astragalus (Fabaceae), is one of three major centers of diversity, all of which comprise the majority of the nearly 1750 species of Astragalus worldwide. One of the most diverse species, Astragalus lentiginosus of Section Diphysi, is a polymorphic complex of over 40 varieties,...
