Alisa Paulsen and Dr. Daniel Fairbanks, Botany and Range Sciences In the Western United States, cheatgrass (Bromus tectorum) is often considered to be an undesirable, invasive weed. When cheatgrass is introduced into an area, it can rapidly establish itself as the dominant species, inhibiting re-establishment of native plants1,2 while competing with important grain crops such […]
Effect of Phytoestrogens on Brain Development and Function
Jacob C. Ong and Dr. Edwin D. Lephart, Zoology Phytoestrogens are estrogen-like compounds derived from plants such as the soy plant and can mimic the function of the human estrogen hormone by binding to estrogen receptors. Estrogen plays a major role in the prevention of osteoperosis and cardiovascular disease in woman. Evidence also suggests that […]
A Comparison of Various Contraction Intensities in Contract-Relax Proprioceptive Neuromuscular Facilitation Stretching of the Hamstring Muscle Group
Heather Nielson and Dr. Brent Feland, Physical Education Proprioceptive neuromuscular facilitation (PNF) is a popular stretching method that increases flexibility. There are several different methods of PNF, but they all usually require the assistance of another person. The contract-relax method is a widely used PNF techniquei that utilizes maximum voluntary isometric muscle contraction (MVIC) followed […]
Selenium-Regulation of Steroid Hormone-Mediated Gene Expression in Transformed Human Prostate Epithelial Cells
David R. Nielsen and Dr. Merril Christensen, Food and Science and Nutrition Introduction Prostate cancer is the second leading cause of cancer-related deaths in American men, with current estimates projecting 179,300 new cases and 37,000 deaths this year [1]. The development of prostate cancer may be divided into three stages: initiation, promotion, and progression. During […]
Vitamin Enhanced Cancer Chemotherapy Using 13-CIS- Retinoic Acid, Vitamin E Succinate and 5-Fluorouracil
Marcus C. Neuffer and Dr. Byron K. Murray, Microbiology Recent studies have suggested that vitamins and vitamin derivatives can enhance the efficacy of chemotherapeutic drugs (2,3). In this study the combination of 13-cis-Retinoic Acid (RA), a Vitamin A derivative, and Vitamin E Succinate (VES) are used with the chemotherapeutic agent 5-Fluorouracil (5FU). Previous studies have […]
Construction of a COL11A1 Transgene and the Study of the COL11A1 Mutation in Mice
Dana L. Murphy and Dr. Laura C. Bridgewater, Zoology Collagen fibrils play an important role in proper skeletal development. Defective collagen can cause human skeletal disorders such as osteoarthritis that affects an estimated 20.7 million Americans. A particular mouse line, housed here at BYU, contains a mutation in the Col11a1 gene. This mutation results in […]
Follicular Dendritic Cells, HIV and Haart Treatment
Jason Meyer and Dr. Gregory Burton, Microbiology The use of highly active antiretroviral therapy (HAART) for HIV-infected patients can result in the reduction of plasma viral RNA levels to nearly undetectable levels. However, the existence of replication competent virus from chronically infected CD4+ T cells despite apparently successful HAART treatment suggests the existence of protective […]
Proton Conductance through the Membrane Protein Gramicidin M
Jason D. Merrell and Professor David D. Busath, Zoology After discussion with my faculty mentor, together we decided that my original ORCA proposal would not best suit the needs of the laboratory in which I am allowed to work. Upon reaching this conclusion, a new research plan was organized. The following outlines the progress of this new […]
Determining Homology of Turkey Round Heart Disease Marker Sequences: A Computer-Based Study
Ryan D. McAllister and Dr. David Kooyman, Animal Science Round heart disease (RHD) is a spontaneous occurring cardiomyopathy in turkeys. The domestic turkey Meleagris gallopavo is affected by low body weight and premature death due to congestive heart failure from RHD (1). RHD results in decreased profitability for the animal agriculturists and higher prices for […]
Walking stick (Insect: Phasmida) Phylogeny and the Evolution of Insect Flight Based on Molecular Data
Taylor J. Maxwell and Dr. Michael F. Whiting, Zoology The evolution and development of wings and flight has fascinated scientists for decades. From our research we happened upon an exciting discovery concerning flight in the phylogeny of walking sticks. A basic phylogeny was to be reconstructed from molecular data with the purpose of understanding the […]
