Parameter estimation and data reduction for cellular biophysical analysis
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Accurate estimation of cellular permeability parameters are an important part of designing and developing optimized cryopreservation protocols. Electronic Particle Counters measure cell volume by detecting changes in ...
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 ...
Characterization of a putative mutant for iron homeostasis
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Little is known about the genetics of iron homeostasis in plants. A novel genetic screen was used to identify mutants with alterations in iron homeostasis. Because Ferritin (Fer1) mRNA expression is upregulated by intracellular ...
Storing hydrogen, by enhancing diamond powder properties with CaF2 and KF for use in fuel cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Whaaaat!!!!!!!!! Hydrogen as a fuel? Yes just like you read it, hydrogen is becoming the best alternative to change our economical dependence on fossil fuels. Today fossil fuels are the main source of energy in the world, ...
Effect of clearcutting on the habitat within the clearcut and the surrounding forest and its relationship to the presence of wood thrush (Hylocichla mustelina) in the Current River Conservation Area
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Wood thrush were one of the few species of forest birds that increased in density on sites that received even-aged management as part of the Missouri Ozark Forest Ecosystem Project (MOFEP). One hypothesis is that this may ...
Progress in the synthesis of a Technetium-labeled complex as a potential Sigma receptor binding ligand
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The sigma receptors have been known to affect several physiological functions such as psychosis, depression and uncontrolled cell proliferation. But what makes the sigma receptors so great is the fact that they bind a ...
Single component vs. whole furniture packing in virtual reverse manufacturing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Previous research studies have analyzed the issues associated with the computer integration of the various technologies now available for hardwood log sawmills. These new technologies were created to optimize the quantity ...
Doping of natural diamond powder with boron to increase its hydrogen storage capacity
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Have you asked yourself what will happen when we run out of fossil fuels, where will our electric power come from, how would we be able to transport ourselves over long distances? Think about what will happen to our economy ...
L-NAME treatment in pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Nω-nitro-L-arginine-methyl-ester (L-NAME) inhibits the enzyme nitric oxide synthase (NOS) which generates the physiologic messenger gas, nitric oxide (NO). In addition to its role as a vasodilator NO inhibits inflammation ...
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, ...
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. ...
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 ...
