Rapid automated characterization of transposon insertion mutants in Desulfovibrio vulgaris Hildenborough by srnPCR [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Tn5 transposon mutagenesis occurs by a mechanism in which a segment of DNA (transposon) encoded in a plasmid is inserted into genomic DNA (the target) by a conservative (cut-and-paste) mechanism (Fig. 2). When the insertion ...
Photoacoustic detection of circulating melanoma cells in the plasma layer of the blood [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
When a melanoma patient is diagnosed, aggressive treatment is advised in an effort to contain the disease. Although the initial malignant cells are destroyed, it is impossible to determine whether or not the cancer has ...
Impact of prior/concurrent exposure to infectious diseases on variability in the 1918-19 flu epidemic on Newfoundland [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Between 1918 and 1920 nearly 2000 people on the island of Newfoundland died from influenza, pneumonia, and related illnesses. Deaths were recorded from all parts of the island, but there is substantial regional variability ...
Sigma receptor binding in normal mouse lung membranes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The brain and many peripheral tissues (e.g., heart, spleen and liver) express sigma receptors that have been characterized by radioligand binding studies in vitro. In vivo studies indicate that sigma receptors are expressed ...
QTL mapping of suppressor of plant blotching1, modifiers of an epiallele [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Pl1-Blotched is an epigenetically regulated allele (an epiallele) of the purple plant1 gene, which activates synthesis of purple anthocyanin pigments. We identified a modifier called Suppressor of plant blotching 1 (Spb1), ...
Analysis of genetic drift within the highly repetitive KSP repeat domain and neurofilament medium [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Axonal diameter is one key component utilized to determine conduction velocity. However, the mechanism that influences axonal diameter must be stable within a given species, but flexible enough to adjust to the evolution ...
Empowerment through journalism: social change through youth media production in northeast Brazil [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Journalism is a process in which people can begin to understand their realities and can be used as a powerful force in democratic societies for or against change. Specifically, youth journalism engages students in identifying ...
Grief: A gendered approach to the elegies of Plath and Lowell [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Landmark studies by psychologists Kalish and Reynolds in the 1970s and de Ridder in 2000 have confirmed distinct differences in grieving strategies between men and women, but the complex problem of grief remains ambiguous. ...
Exposure to explicit sexual media impacts men's perceptions of women's motives for sexual intercourse [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Previous studies have shown that exposure to sexually explicit media can influence males' attitudes toward sex and their sexual partners, their behaviors, and their emotions. Researchers found increased aggression towards ...
Thrust and torque response for drilling titanium and carbon composite sandwich materials [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Experiments were conducted based upon previous research conducted by El-Gizawy and Khasawneh [1] to determine the time response of thrust force and torque correlated to a simple drilling procedure through carbon fiber ...
South Korea protein demands [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Over the last 10 years South Korea has had experienced a steady increase in population averaging an increase of approximately 1% a year. They have also been able to acheive economic growth with a GDP that is almost two and ...
The elderly, parent-child relationships and AIDS in rural South Africa [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Using qualitative interviews, we explore the impact of the AIDS epidemic on parent-child reciprocity relationships, from the perspective of young and old rural South Africans. Typically, adult children provide monetary ...
Public perceptions of the environment: The role of mass media [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This project examines the relationship between television news coverage of environmental issues and variations in public concern for the natural environment in the United States. Aggregate-level, time series data (GSS; ...
Do type I collagen defects that cause Osteogenesis Imperfecta result in an inherent muscle pathology? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Osteogenesis imperfecta (OI) is a congenital connective tissue disorder characterized by decreased bone mineral density and increased bone fragility and susceptibility to fracture. In addition to skeletal fragility, patients ...
Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Molybdenum-99 (Mo-99) is used to create Tc-99m, a widely used nuclear medicine diagnostic imaging radioisotope. In an attempt to decrease the need for imported Mo-99, development of mechanical systems to efficiently prepare ...
MCP-1 and its role in lyme arthritis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Lyme disease is caused by infection with the bacteria Borrelia burgdorferi, causing arthritis and carditis in infected animal models. The presence of spirochetes in the joint and other soft tissues induce recruitment of ...
