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 ...
Terrestrial movements and foraging behavior of the gray treefrog during the breeding season
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Currently, conservation techniques aim to preserve metapopulation dynamics in order to prevent species' extinction. A metapopulation is composed of multiple populations that interact by the exchange of individuals. This ...
What role does phosphorylation of cardiac troponin I play in elevating cardiac contractility following adrenergic stimulation?
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Myocardial performance is enhanced when adrenergic receptors are stimulated by catecholamines. The enhanced performance is mediated by cAMP dependent protein kinase A (PKA), which phosphorylates several proteins within the ...
Differences in parents', siblings', and observers' ratings of family interaction tasks
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
(Campione-Barr & Smetana, 2004). The authors of the present study examined these differences but, within family (with older and younger siblings) and hypothesized that interactions with older siblings would be rated as more supportive and involved...
Subcellular localization of the Arabidopsis thaliana atDjC37 molecular chaperone protein
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
DjC37. It has been previously determined that atDjC6 is nuclear localized (Suo & Miernyk 2004 Protoplasma 224: 79-89). We now wish to determine the subcellular localization of atDjC37. In silico analysis of the atDjC37 deduced amino acid sequence (http...
Will the ethanol industry become America's solution to its dependence on foreign crude oil? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
on farm program by $3.2 billion in 2004. However, the ethanol industry remains focused on the keeping their costs of production low. Costs include variable expenses for inputs like corn and natural gas and capital expenses for plant construction...
Study of auxin responsive gene promoters in transient expression assays
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Transfection assays are an important tool for biochemists; the comparatively quick technique allows experimenters to see relative levels of expression of a particular gene in the presence or absence of a plant hormone ...
Kinetics vs. equilibrium binding: Determining the mechanism of transcriptional activation of Polymerase II
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
research, the equilibrium binding constants of wild-type TFIIIA-VP16 and two mutants, L148F and L148H, were determined, along with the half lives of the DNA-protein binding complexes containing these proteins. It was found that the equilibrium constants...
Bovine oocyte permeability in 1, 2-propanediol
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Cryopreservation of oocytes is of great importance both in medical research and in the agricultural industry. Cryopreservation of oocytes allows for future breeding of selected genetic lines of animals. Effective cryopreservation of bovine oocytes...
Vocabulary growth through reading in adolescents with language learning disabilities: A case study [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
written exposure to words. Vocabulary acquisition through reading happens incrementally. Following an initial exposure, children acquire a form of partial word knowledge (Wagovich & Newhoff, 2004). Over time and with additional exposures to a word, a more...
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 glands to regulate...
Identification of chloroplast DNA insertions in nuclear chromosomes of maize B73 line using the FISH procedure
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It is known that chloroplast DNA can incorporate itself into the nuclear genome of plants. However, the sites of chloroplast (ct) DNA integration into chromosomes of maize have not yet been analyzed. This project is the ...
Purification and analysis of human muc reporter proteins
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Exocrine mucous glycoproteins are a family of multifunctional heavily glycosylated, anionic macromolecules that typically possess a high serine/threonine content. The size and complexity of these glycoprotein molecules, ...
Unequal reinforcement values from equally warm and cool temperatures in Drosophila
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Insects inhabit extreme temperature environments and have evolved mechanisms to survive there. When temperatures either rise or fall, small insects alter their behavior within seconds to avoid, in extreme situations, ...
Comparison of different methods for removing metals from resins for applications to radiochemical seperations
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Metallic contamination has been a problem for many years in the environmental field. Soil, water and air have been polluted by many different trace metals that finally affect humans by consumption of natural products, ...
Factors that affect the degree of axonal regeneration following spinal cord transection in larval lamprey
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In all vertebrate animals, reticulospinal (RS) neurons in a locomotor “command” systems in the brain send neural processes to the spinal cord to activate “central pattern generators” (CPGs) and initiate locomotor behavior. ...
Identifying Lepidopteran resistance within hcf mutants
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Southwestern corn borer (SWBC) and fall armyworm (FAW) feeding on maize causes extensive crop damage in the United States. Total crop loss is valued at approximately 300 million dollars annually. Previous proteomic analysis ...
Immunological analysis of a putative virulence protein of Haemophilus influenzae
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Haemophilus influenzae, a gram negative bacterium, is part of the normal flora of the human upper respiratory tract; however, they are also known to be pathogenic. Nonencapsulated (nontypeable) H. influenzae (NTHi) are ...
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 ...
Stem cells transplanted into the brain are immunogenic and are actively rejected by the host [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
for neural cells lost due to injury or disease. However, rejection of donor cells by the host immune system may limit the effectiveness of stem cell therapies. Recent research has suggested that some stem cells may be immunoprivileged, able to avoid rejection...
