Organization of the command system in the lamprey brain that initiates locomotor behavior
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In vertebrate animals, the muscle activity pattern for locomotor behavior is produced by central pattern generators (CPGs) in the spinal cord. In the brain, “command” systems, which have several levels, process information ...
A habitat model to predict deer-vehicle accidents in Columbia, Missouri
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Studies show that in a suburban setting white-tailed deer live comfortably with humans and human-associated disturbances. Wildlife ecologists have developed models to predict where deer occur using information such as; ...
Protoemics of integral membrane proteins from developing Brassica napus
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
As plant seeds develop the accumulation of natural products, starch, oil, and protein undergo dramatic changes. At the early stages of seed filling in oilseeds starch is the principal component. Oil (triacylglycerol) and ...
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 ...
Two-parameter model of cell membrane response to cryoprotectant agents
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Cryobiology is a widely applicable topic of biological science. From thoroughbred horse gene preservation to organ transplants, the applications of cryobiology, specifically cryopreservation, are broad. The two major ...
Characterization of degeneration in the retina, brain and spinal cord of the Cln1 knockout mouse
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The neuronal-ceroid lipofuscinoses (NCLs; often referred to as Battens Disease) are a group of hereditary disorders of childhood. Symptoms of NCLs are characterized by neurodegeneration with progressive neural cell death ...
Won't you be my neighbor? An analysis of the effect of density on floral and nectar traits in Nicotiana alata
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
It has been shown that heritable, genetic variability can change in response to different environmental conditions (Hoffmann and Merila 1999) and also that some plants can sense proximate neighbors and change their growth ...
Modeling firing patterns of medium spiny neurons
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The alternation in firing patterns of medium spiny neurons of the Nucleus Accumbens , a key structure in the brain's reward pathway, due to chronic and acute cocaine use was investigated through change of ion channel and ...
Effects of diet and exercise on carotid lesions in male pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The objective of this study was to examine the influence of aerobic exercise-training on atherosclerotic lesion appearance and composition in the carotid artery of male, miniature Yucatan pigs fed a high-fat, high-cholesterol ...
Evidence that glutamate induced neurite retraction of reticulospinal neurons is dependent on calcium influx
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Locomotor systems of vertebrates consist of a command system in the brain that activates central pattern generators in the spinal cord to initiate locomotor behavior. Reticulospinal (RS) neurons are the output neural ...
Shipping Box Radiation Level Detector
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Shippers at the University of Missouri Research Reactor (MURR) are currently being exposed to radiation while manually testing the radiation level of outgoing shipping boxes. The boxes contain radioactive isotopes used in ...
Use of antisense oligonucleotides to enhance exon 7 incorporation in the pre-mRNA splicing of SMN2
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Spinal muscular atrophy (SMA) is a neurodegenerative disorder that is relatively common in humans and is caused by loss of the survival motor neuron 1 (SMN1) gene. SMA is the leading cause of hereditary infant mortality ...
A kinetic study of active site mutations in GDP-mannose dehydrogenase
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
In the human pathogenic bacterium Pseudomonas aeruginosa, GDP-mannose dehydrogenase (GMD) serves as a critical enzyme in the biosynthesis of alginate, a polysaccharide that functions as a protective coating against antibiotics ...
The correlation between Chicano theater and Augusto Boal's Theater of the Oppressed
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
"The theater is a weapon, and it is the people who should wield it" are words that come from the Brazilian Dramatist's, Augusto Boal, commentary, The Theater of the Oppressed. What Boal is referring to is that the theater ...
Natural variation in Arabidopsis thaliana: Molecular genetic architecture of stress tolerance under water deficit
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
The functional genomics tools available for studying Arabidopsis thaliana are a great resource for researchers trying to characterize and understand the genetic basis of natural variation. Genome wide transcript profiling ...
Uranium: The problem, or the solution?
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Uranium is of great importance as a nuclear fuel and is used to generate electrical power, produce isotopes, and to make weapons. The possibility of developing a realistic flow scheme for nuclear fuel reprocessing or ...
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 ...
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 ...
Involvement of TolC protein in the export of siderophore enterobactin in Escherichia coli
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
