Effects of Elevated Temperature on Mycobacterium chelonae Growth and Mycobacteriosis in Zebrafish (Danio rerio)

Creator:

Lopez, Elizanette V.

Abstract:

Utilization of zebrafish, Danio rerio, has steadily increased and its applications have expanded into numerous fields of science. Applying elevated temperatures (32°C to 37°C) to this organism has allowed researchers to conduct climate change, human cancer and infectious disease studies. Though zebrafish can be acclimated from the standard 28°C to...

Masters Thesis
Yosemite region nitrogen deposition and patterns in the composition of lichen communities

Creator:

Hutten, Martin

Abstract:

This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...

Mechanisms that influence the posttranslational modification of the GluN2B subunit in the aged brain

Creator:

Zamzow, Daniel R.

Abstract:

Memory is essential to everyday life. As we age, deficits in memory become apparent. The toll of age-related cognitive impairment can be devastating to families and costly to society. The NMDA receptor is a molecule in the brain that is instrumental in the formation of memories. The receptor is particularly...

Hidden dynamics : community ecology and costs of parasite infection in African buffalo (Syncerus caffer)

Creator:

Henrichs, Brian

Abstract:

Most wild animals are concurrently infected with multiple parasite species for most of their lives. These parasite species assemble into rich and diverse communities, with parasites using host tissues for growth and reproduction as well as evolving strategies to evade the host immune system. The net effect of these ecological...

Masters Thesis
The determination of alkaline phosphatase activity and analysis with a portable clinical analyzer of serum and peritoneal fluid from horses suffering colic

Creator:

Saulez, Montague N.

Abstract:

Alkaline phosphatase (ALP) is an enzyme present in intestinal mucosa, bile, bone and renal tubule cells. Bile acids have been shown to decrease ALP activity from bone and kidney but not those from intestinal origin. This action can be mimicked in serum and peritoneal fluid samples by the use of...

Masters Thesis
Indole-3-carbinol in the maternal diet provides chemoprotection for the fetus against transplacental carcinogenesis by dibenzo[a,l]pyrene in the B6 129 mouse model : role of the Aryl Hydrocarbon Receptor

Creator:

Yu, Zhen

Abstract:

Lymphomas and leukemias are the most common cancer in children and young adults and in utero exposure to carcinogens may contribute to the etiology of these cancers. A polycyclic aromatic hydrocarbon (PAH), dibenzo[a,l]pyrene (DBP), was administered to pregnant mice (15 mg/Kg b.w., gavage) on gestation day 17. Significant mortalities in...

Ascospore viability and dispersal from pruned branches infected with Anisogramma anomala

Creator:

Heckert, Stephanie

Abstract:

Viability and dispersal of ascospores of Anisogramma anomala, the cause of eastern filbert blight (EFB) on European hazelnut, from diseased branches pruned from trees were measured. In each of two years, branches bearing stromata of A. anomala were cut in mid-December and compared to branches cut near budbreak in March,...

Masters Thesis
Differential gene expression in the pregnant bovine corpus luteum during maternal recognition of pregnancy

Creator:

DuBay, Kristi M.

Abstract:

Interferon tau (IFN-τ) is the pregnancy recognition signal secreted by the trophectodermal cells of the developing bovine embryo that prevents luteolysis and maintains critical progesterone production. Recent evidence has suggested in addition to the mechanism of action identified in the uterus, there may be a direct effect of IFN-τ on...

Masters Thesis
Chemical cues and the molecular basis of olfactory chemoreception in caudate amphibians

Creator:

Kiemnec, Karen M.

Abstract:

Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...

Dissertation
Effects of environmental stress on intertidal mussel reproduction

Creator:

Petes, Laura E.

Abstract:

Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...
