Diversity of progeny from a single colony of Salmonella typhimurium after 19 months in sealed agar stabs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Recent studies at the Cancer Research Center revealed numerous mutations in Salmonella typhimurium that had been sealed in agar stab vials and stored for over forty years. The bacteria that were conserved in over 20,000 ...
The effects of arousing video on attention and memory for attack vs. non-attack political advertisements
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
During the election season, it may appear that television viewers are bombarded with political advertisements. Furthermore, it may also appear that the majority of these advertisements are routinely negative. It has been ...
Pharmacokinetic modeling of cortisol binding to dietary fiber in the gastrointestinal tract
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Cortisol is a glucocorticoid hormone produced in the adrenal cortex during stressful situations. The purpose of this project was to determine whether cortisol binds to dietary fiber and to design a pharmacokinetic model ...
Examining the consequences of stalking misconceptions
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It has been proven through previous research that stalking is a form of intimate violence. It is possible that by researching other forms of intimate violence, such as rape, we can come to gain a better understanding of ...
Fuel system design for an adsorbed natural gas vehicle
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
With energy and environmental concerns mounting as the global energy demand increases, alternative fuels are drawing more and more attention. Natural gas is one such alternative fuel. However, the major shortcoming of ...
Effects of prenatal exposure to xenobiotic estrogen and the development of endometriosis in adulthood
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Endometriosis is an estrogen-dependent disease that affects millions of women worldwide, causing pain and infertility. While it is known that retrograde menstruation places endometrial tissue in the peritoneal cavity, it ...
In vitro evaluation of In-111-DOTA-anti-bcl-2-PNA-Tyr-3-octreotate in Chronic Lymphocytic Leukemia cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The B-cell lymphoma/leukemia-2 (bcl-2) gene is overexpressed in many cancers. This gene increases cell survival by blocking apoptosis, or programmed cell death. The objective of this study was to evaluate radiolabeled ...
Construction of a tatA Desulfovibrio vulgaris Hildenborough
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
tatA Desulfovibrio vulgaris Hildenborough is a member of the obligately anaerobic bacteria growing by sulfate respiration and involved in environmental biocorrosion of ferrous metals. It also shows potential for bioremediation ...
Protein secondary structure prediction: Creating a meta-tool
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Protein structure prediction is a growing field of interest for a many varied reasons, owing not only to its obvious utility, but also the success that applying newer mathematical tools has garnered in recent years. Despite ...
Oil bodies isolated from Brassica napus mature seed
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Plants store seed triacylglycerols in discrete lipid monolayer storage organelles called oil bodies. Only two proteins have been characterized from oil bodies, namely oleosin and caleosin, which are both integral membrane ...
Development of an assay to measure cortisol using a standard glucose meter
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
When an animal is stressed many changes occur, such as altered behavior and reduced resistance to disease, and these effect population performance (Millspaugh 2004). Cortisol is a stress hormone produced by the adrenal ...
Efficacy of high levels of microbial phytase in improving phytate Phosphorus utilization by turkeys
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
A 14-day study was conducted with 750 female turkey poults to determine the efficacy of high levels of phytase in improving turkey performance and percent and milligram toe ash. Six dietary treatments were assigned to five ...
The relation of childhood depressive symptoms to behavior during a speech task
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study examined the relation of child depressive symptoms to their observed behaviors during a speech performance task. Previous work (Mavers & Bell, 2005) has demonstrated that children's anxiety was related to several ...
Does genetics play a role in feeding behavior of gray tree frogs?
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Models of sexual selection suggest that, in some animals, females choose mates of genetically superior quality. In the gray tree frog Hyla versicolor, it has been shown that females prefer male advertisement calls of long ...
Evaluation of the efficacy of test products to ameliorate the toxic effects of aflatoxin present in broiler chick diets
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
An in vivo study was conducted to evaluate the efficacy of several adsorbent test products to ameliorate the toxic effects of aflatoxin B1 (AFB1) in chicks. Ninety day-old straight run chicks were purchased from a commercial ...
Determining an efficient protocol for production of neural stem cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Mouse embryonic stem (ES) cells are pluripotent cells derived from the inner cell mass of the developing blastocyst. When cultured in non-adherent dishes, ES cells form free-floating embryoid bodies (EBs). Cells within the ...
Identifying plant resistance pathways in Arabidopsis thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The destruction of plants by a pathogen results in millions of dollars lost in crop yield annually. Identifying the plant response pathway to the presence of a pathogen is key to combating plant disease. The gene-for-gene ...
