Establishing the status of the American black bear in southern Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The current status of the black bear population in Missouri is largely unknown, as we have little to no information concerning its size, reproductive status and origin. However, evidence suggests that the bear population ...
What's in a worm; Uncovering polymophisms in soybean cyst nematode parasitism genes that correlate with virulence
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Soybean cyst nematode (SCN) is a parasitic worm that penetrates and infects soybean roots resulting in billions of dollars in crop loss annually. The most cost effective and environmentally friendly SCN management strategy ...
Are age-related differences in associative memory mediated by sensory decline? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Naveh-Benjamin (2000) suggested an associative deficit hypothesis, explaining that some of the decline in episodic memory in older adults is due to their difficulty in binding unrelated components together into a cohesive ...
Regulation of menaquinone production in Desulfovibrio vulgaris Hildenborough and Desulfovibrio desulfuricans strain G20 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Menaquinones are cytoplasmic membrane components that have important roles in electron transport for energy generation in anaerobic bacteria. A simple and sensitive protocol for the purification and quantification of ...
Media lynching on the campaign trail [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This is a multidisciplinary research project that is about the use of race in political ads from 1988 to 2006. Although the student researcher has analyzed five political ads, only one of the ads, “The Willie Horton” ad, ...
The formation of cysteine-tyrosine crosslinks via a sulfenic acid intermediate [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Cysteine residues in proteins are readily oxidized to sulfenic acids. Sulfenic acids, in turn, can act as potent electrophiles that have been observed to form intrastrand protein crosslinks with neighboring amide or cysteine ...
Plasma surface modification of silica particles for the increased strength of dental composites [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Many of the problems that exist today with current dental restoration materials can be eliminated through the use of nanofiber fillers such as hydroxyapatite. Materials like this can ultimately provide greater strengths ...
Functional analysis of conserved amino acid residues in the C-terminus of ACC synthase
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Ethylene is an important plant hormone that regulates growth, development, and stress response. Synthesis of Ethylene from its immediate precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), is catalyzed by ACC oxidase. ...
Interaction of a heterodimerization partner with glucocorticoid receptor (GR), androgen receptor (AR) and GR/AR hybrids
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Steroid hormones are a class of compounds that play a role in regulating many functions. Glucocorticoid hormone is a compound in this class, which helps maintain homeostasis, including regulation of production of γ-fibrinogen, ...
The effect of reduced chromatin gene expression on an epigenetically regulated maize gene
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In virtually all eukaryotic organisms, not just plants, genes are regulated at the level of chromatin. In a genomics approach to understand how expression of a gene can be regulated by its chromatin configuration, a series ...
The intramolecular, stereoselective addition of sulfoximine carbanions to electron deficient alkenes
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Chiral Benzothiazine play important roles in synthetic organic chemistry since they can be used in the preparation of enantiomerically pure compounds. We have studied the synthesis of these species using the intramolecular, ...
Novel inhibition mechanism and potent antiviral activity of translocation-deficient reverse transcriptase inhibitors [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Nucleoside RT inhibitors (NRTIs) are among the most potent anti-HIV agents and act as chain terminators because they lack a 3'OH. However, this feature can reduce affinity for RT compared to the analogous dNTP substrate, ...
Assessing the value of agricultural streams as amphibian refuges [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Although many causes for worldwide amphibian population declines are under investigation, the destruction and alteration of aquatic habitats remains a primary threat. In agricultural landscapes, natural wetlands are often ...
Efficacy of a modified constraint induced movement therapy protocol in the clinical setting [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Constraint induced movement therapy (CIT) is an intervention strategy used by rehabilitation therapists for people who have experienced stroke. Traditional CIT protocols require participants to wear a restraint on their ...
Generating Gbx2 antibodies: A useful tool in determining developmental mechanisms regulated by GBX2 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The GBX class of homeobox genes is comprised of Gbx1 and Gbx2. Both loss-of-function and gain-of-function studies in mice have shown that Gbx2 is vital for normal anterior hindbrain development of mammalian organisms. To ...
Silencing of three members of the cytochrome p450 family of genes to uncover their role in iron regulation in A. thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Iron absorption and distribution by an organism needs to be tightly regulated because iron is essential but in excess it can be dangerous and may even result in death. Through microarray analyses of iron-starved Arabidopsis ...
Expression of aT4g27260/GH3-5/GH3a studied with in situ hybridization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tropisms, the responses of plants to external stimuli, have been studied as important evolutionary adaptations and as possible areas of future advantageous genetic manipulation. The goal of our current research is to ...
Benefits of soy-based feeds for fetal estrogen levels and obesity in adulthood
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
We examined the effect of maternal exposure to naturally occurring estrogenic chemicals in diets on circulating levels of estradiol in mouse fetuses. An animal's specific response to estrogen can vary according to the time ...
Mitochondrial DNA insertion into nuclear chromosomes of maize
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Every mitochondrion contains its own DNA separate from the nucleus. Over evolutionary time, most of the mitochondrial genes have moved to the nucleus so that now mitochondria require nuclear DNA to function. This type of ...
