Selective precipation of seed storage proteins in soybeans: Reducing the dynamic range of protein expression for in-depth proteome studies
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Seed storage proteins (SSPs) are a class of proteins which accumulate at high levels (up to 60% total protein) during plant seed development as a nitrogen reserve for germination. Due to the preponderance of SSPs, the ...
Modeling the flow of digesta through the ruminant reticulorumen
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Ruminants possess a specialized gastrointestinal (GI) tract that enables them to efficiently digest fibrous feeds. The first stomach compartment of the ruminant GI tract, the reticulorumen (RR), is the site of most fiber ...
Estrogen receptors in TRAMP C2 cells

According to a 2005 study done by the American Cancer Society, prostate cancer is the second most common type of cancer among American men. It has been shown that estrogen receptors alpha and beta play significant roles ...
The impairment of the prefrontal cortex due to high levels of dopamine and norepinephrine in relation to ADHD
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Attention- Deficit/ Hyperactivity Disorder (ADHD) affects many people from various backgrounds; however, not much is known about the disorder aside from clinical symptoms. Researchers are just beginning to dissect ADHD and ...
Metro and nonmetro youth: Evaluating differential pathways to delinquency
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Although much research has been conducted on risk factors and behaviors of delinquent youth, little is known about the nonmetro population and how they may differ from their metro counterparts. The purpose of this study ...
Sex and age specific infestation rates of raccoons (Procyon lotor) by American dog ticks (Dermacentor variabilis)
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
American dog ticks (Dermacentor variabilis) can have profound direct and indirect effects on human and wildlife hosts. However, there is little information on their short- or long-term rates of parasitism in free-ranging ...
Investigation of type I collagen deposition in the glomeruli of COL1A2 deficient mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Type I collagen is the most abundant structural protein in the body, playing a major role in the strength and integrity of connective tissues. Alterations in the synthesis and structure of type I collagen result in a number ...
Involvement of TolC protein in the export of siderophore enterobactin in Escherichia coli
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
To acquire the necessary iron against harsh competition in the environment, iron starved bacteria synthesize, excrete and retrieve iron scavenging molecules termed siderophores, one of which is enterobactin. TolC protein ...
Modern day Jezebels: Racialized sexuality and the images of black women in contemporary hip-hop videos
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Hip-hop music emerged in the 1970's as a countercultural strategy to deter inner city youth from the influence of violence and gangs; it was a form of social expression. The dominant images in early hip-hop music videos ...
A study of wireless sensor networks with focus on node localization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Due to research in low-power, cheap wireless communications, Wireless Sensor Networks (WSN) has become one of the most exciting new fields of interest within computer science and engineering. Just as the Internet has made ...
Effect of Salmonella typhimurium on human cancer line tumors in mice [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Research of bacteria-driven degeneration of tumor cells, initially pioneered by Dr William Coley in 1893 using heat-killed mixtures of streptococci, has led to the scrutiny of the enterobacteria species Salmonella typhimurium ...
Neonatal exposure to xenobiotic estrogen may alter the adult immune response and exacerbate endometriosis in mice [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Endometriosis is a common medical condition affecting 5-10% of women worldwide and often results in severe cramps, pelvic pain, and infertility. The condition occurs when endometrial tissue, which escapes into the peritoneal ...
Role of the domain 4 rotation in PMM/PGM from P. aeruginosa during catalysis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The enzyme phosphomannomutase/phosphoglucomutase (PMM/PGM) belongs to the alpha-D-phosphohexomutase enzyme superfamily. It catalyzes the reversible conversion of 1-phospho to 6-phospho sugars. The reaction mechanisms ...
Characterization of transposon insertion mutants in desulfovibrio vulgaris hilderborough by sequencing genomic DNA [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
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. When the insertion position ...
Testing the neural locus of affective priming effects [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Research has consistently shown that participants are faster to categorize the valence (positivity or negativity) of an affective target when it is preceded by a stimulus (prime) that shares its valence compared to one ...
