Desiccation rates of Rana sylvatica, Rana clamitans, and Bufo americanus in a fragmented forest
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Habitat loss and fragmentation are the primary causes in the declines of amphibian populations. Farming, urban sprawl, and logging have created a mosaic of developed and undeveloped land that may create barriers between ...
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 ...
Brain natriuretic peptide decreases pulmonary artery pressure in rats with pulmonary hypertension
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
INTRODUCTION: B-type or Brain natriuretic peptide (BNP) was first isolated from the porcine brain, but it is primarily secreted from the cardiac ventricles in humans. As a cardiac hormone it has a physiologic regulatory ...
A study of academic self- concept, academic motivation, and self- esteem: Their relationship to academic achievement in college students
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study examined the reliability of the Academic Motivation Scale in a group of 263 undergraduate students enrolled in undergraduate psychology classes at a large Midwestern public university. Ethnicity, sex, age, and ...
Diversity of progeny from a single colony of Salmonella typhimurium after 19 months in sealed agar stabs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Recent studies at the Cancer Research Center revealed numerous mutations in Salmonella typhimurium that had been sealed in agar stab vials and stored for over forty years. The bacteria that were conserved in over 20,000 ...
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 ...
Recent lateral gene transfer from Pasteurella multocida into Haemophilus influenzae
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Haemophilus influenzae is a gram-negative bacterium that exclusively colonizes humans. Nonencapsulated strains of the bacterium are found in the upper respiratory tract of healthy humans, but can also cause the respiratory ...
Calix[n]arene derivatives for gas storage
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The calix[n]arenes are versatile inclusion compounds (Scheme 1) comprise of cyclic, polyphenolic compounds that can be tailored synthetically by altering X, Y, R and n. In solid state, we found simple calixarenes are quite ...
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 ...
The measurement of residual feed intake to determine feed efficiency of pregnant Hereford heifers
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The large potential improvement in profitability is what makes feed efficiency such a studied and concerned topic in the beef industry today. Currently, no herd exists in the United States that has been selected solely for ...
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 ...
