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 ...
The influence of increased contact rate among raccoons on a nematode of public, and wildlife health concern, Baylisascar [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Natural and anthropogenic fluctuations in resource availability can alter the behavioral ecology and population dynamics of wildlife. This may have unintended consequences to wildlife disease ecology, as theoretical models ...
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 ...
Pathogen susceptibility to Pseudomonas syringae in Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Peptides may act as regulatory molecules that coordinate cellular responses needed for growth, differentiation and development. A novel family of small peptides, encoded by the DEVIL (DVL) gene family, was identified in a ...
Analysis of Arabidopsis thaliana mutants defective in the oligopeptide transporter OPT3
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The transport of peptides across membranes is a phenomenon found in both prokaryotes and eukaryotes as a method of obtaining amino acids, nitrogen, and carbon. Peptides can be transported by ATP-dependent transporters, as ...
Functional analysis of MAP kinases in Arabidopsis thaliana: Fully rescuing the mpk3/mpk6 mutant phenotypes
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Mitogen Activated Protein Kinase (MAPK) cascades are three-stage modules involved in signal transduction. MAPKs function at the lower tier of these cascades and they phosphorylate transcription factors and other protein ...
Binding properties of X29 protein and RNA
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The Peculis Lab previously demonstrated that X29 protein binds U8 snoRNA with high affinity and specificity in Xenopus Laevis [1]. U8 snoRNA is a C/D box RNP required for pre-rRNA maturation of 5.8s and 28s rRNA in the ...
Video game music beyond its original function: Practices, styles, and ends
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Rapidly growing in complexity of compositional practices, styles, and ends, video game music is an art form that surpasses its original function as “background music” as well as any utilitarian, stereotypical expectations ...
Comparison of regulatory regions in the mitochondrial genomes of grasses
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Regulation of transcription in plant mitochondria is not well understood. The recent sequencing of the mitochondrial genomes of 10 closely related grasses allowed a comparative analysis of regulatory regions. To look for ...
Analysis of PDGF-AB and -BB in serum of intact and ovariectomized (OVX) pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Previous studies in our group demonstrated that terminal microvascular networks in dura mater of ovariectomized (OVX) pigs undergo significant remodeling characterized by a decrease in microvessel density, capillary ...
A century later another surprise: A non-visual behavioral function of the white gene
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Discovery of the white mutation in Drosophila melanogaster has broadly influenced our understanding of the mechanisms of inheritance. We recently discovered a role of the white gene in memory formation. Thus, the white ...
Peptidomics of Arabidopsis thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Peptidomics is study of all the peptides in an organism, some of which are signaling molecules. Peptides are polymers of amino acids. For the purpose of this work, peptides are defined as proteins being less than 15 kDa ...
Environmental report actualization for the license renewal of the University of Missouri Research Reactor Center
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Licensing requirements for power as well as non-power reactors must address environmental concerns related to radioactive emissions. The purpose and need for the renewal of the operating license for the Missouri University ...
Evaluating the relationship between leaf nitrogen concentration and Minolta SPAD-502 meter readings [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Oak trees are deciduous trees that can live for up to 200 years and face a variety of environmental stresses. Like all plants, oak trees need nutrients, which vary under different stress conditions. We study nitrogen as ...
Enhancing pond production of large food size-fish by controlling social costs [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The primary study objective determined whether rearing high-percentage-male (> 70 % male) bluegill groups in intensively-managed standard production ponds results in higher fish growth rates and production of higher numbers ...
Improving mouse-DMH screening capability by adding 2000 mouse CpG islands
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
DNA methylation alteration, in correlation with gene expression, is involved in development and progression of many cancers. Using a microarray based method, mouse-DMH (Differential Methylation Hybridization), our lab is ...
A comparative study of the feral horses of Shackleford Banks and Assateague Island [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Feral horses (Equus caballus) can be found today in isolated barrier island populations along the eastern coast of the United States. Assateague Island stretches for 37 miles along the coasts of Maryland and Virginia and ...
