D Craig Seager and Dr. Allan M Judd, Physiology and Developmental Biology The secretions of the adrenal gland are responsible for the body’s response to stress. One of the major mechanisms by which these secretions are regulated is by the way of the hypothalamuspituitary- adrenal axis (HPA axis). However, it was suspected that other mechanisms […]
Tobacco Awareness in American Medical Schools: Comparative Study
Joshua G Schkrohowsky and Dr. Gordon Lindsay, Health Sciences After years of steady decline, the percentage of people who use tobacco in the United States has leveled off and has appeared to even begin an increase. Cigarette smoking remains the single largest cause of preventable death in the United States. It is not only a […]
FDCs in HIV Infected Patients Retain Archival HIV Sequences
Jesse Rowley and Dr. Gregory Burton, Microbiology Introduction Human Immunodeficiency Virus (HIV), the causative agent of AIDS, has eluded successful treatment since its discovery in the early 1980s. The prospect of successful treatment came with the advent of Highly Active Anti-Retroviral Therapy (HAART) which has reduced plasma virus replication to undetectable levels in many patients. […]
The Phylogeny and Evolution of Color Patterning Among the Pleasing Fungus Beetles (Coleoptera: Erotylidae).
James A Robertson and Dr. Michael F Whiting, Integrative Biology The family Erotylidae (pleasing fungus beetles) currently includes 125 genera, and approximately 2,500 described species and has a worldwide distribution. There are five currently recognized subfamilies within Erotylidae: Dacninae, Megalodacninae, Eucaustinae, Tritominae, and Erotylinae. Erotylids are mycophagous, feeding on basidiomycete fungi, and exhibit a wide […]
Phylogeny and Conservation of the Utah Land Snail Oreohelix peripherica (Gastropoda: Pulmonata: Camaenidae)
Ashley Nelson and Dr. Keith A Crandall, Integrative Biology Introduction The land snail Oreohelix consists of 35 species that are distributed throughout the western United States, southwest Canada and northern Mexico. The majority of these species are endemic to the Great Basin and the Rocky Mountains (Bequaert et al., 1973). Pilsbry (1939) made the last […]
Reduction in Toxicity of Doxorubicin by á-Tocopherol Succinate (vitamin E) and Ascorbic Acid (vitamin C) in Human Adenocarcinoma Cells
Christie Michaud and Dr. Byron Murray, Microbiology Colorectal cancer is the second leading cause of cancer deaths in the United States and doxorubicin, is one of the more widely chemotherapeutic treatments for this disease. This study investigated the possibility of exposing adenocarcinoma cells to vitamin C/vitamin E (VC/VE) combinations as a means to reduce toxicity […]
Bacteria as Bioindicators: Bioassessment in the Bonneville Basin of Utah
Mark Merkley and Professor Russell Rader, Integrative Biology Bioassessment is the practice of using organisms to detect environmental health and integrity. Ecosystem health and integrity depend on the interaction between living organism and ecosystem function. All organisms or groups of organisms do not respond the same to environmental stress. Depending on various disturbance characteristics, each group may […]
Hepatic Oval Cells: A Potential Source of Cartilage
Chris Meinhart and Dr. Laura C Bridgewater, Microbiology Damage to articular cartilage found in synovial joints can occur both by trauma and disease processes. Cartilage, because of its avascular nature and low cellularity, has very poor regeneration capabilities. It is therefore important to explore new and effective cellular therapies to facilitate the repair of diseased […]
Investigation Into the Anti-Angiogenic Activities of Convolvulus arvensis Extract
Jeremy F McBride, Rachelle R Olsen and Dr. Kim L O’Neill, Microbiology and Molecular Biology Angiogenesis, the development and differentiation of new blood vessels from the pre-existing vasculature, is a fundamental physiological process involved in growth, development, and wound healing. Loss of control over the biological molecules which regulate this process can lead to pathologic […]
Survey of Calyx Gland Morphology in Navarrettia (Polemoniaceae) Using Scanning Electron Microscopy
Taina Matheson and Dr. Leigh Johnson, Integrative Biology Many flowering plants possess small epidermal hairs and glands. The variation in these features has been used to infer relationships among plant groups. The Phlox family (Polemoniaceae) is one such group. Many species in this family are described as having “woolly or arachnose hairs.” These hairs are […]
