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 ...
Functional analysis of nematode secreted proteins to devise innovative approaches for plant resistance against nematodes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Approximately 1 billion dollars in soybean yield loss is caused annually in the US by a microscopic parasite known as the soybean cyst nematode (SCN; Heterodera glycines). My research is focused on studying cyst nematode ...
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 ...
University of Missouri geotechnical experiment site [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The MU Geotechnical Experiment Site team is conducting laboratory testing on soil samples from a field site consisting of 9 bore holes ranging from a final depth of 20 to 50 foot below the surface. The purpose of this ...
Effects of a helical-grooved wick structure in a thermosyphon solar collector [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The heating of household water, which consists of nearly 20 to 30% of the average household's energy costs, has drastically increased in recent years. Solar water heaters have become popular to lower this cost, and one ...
A human relevant rat model of breast cancer [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Estrogen receptor (ER) status is an important prognostic factor of human breast cancer. ER+ breast cancers, which make up 95% of human breast cancers, have a good prognosis because the growth of these tumors is dependent ...
Is Botswana's economic success story partially explained by its stock exchange? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The objective of this study was to understand whether Botswana's leading world growth in GDP can be partially explained by its accounting reporting and its capital market. We studied economic measures such as gross domestic ...
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 ...
Differential effects of the components of higher education expenditure on U.S. state economic growth [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Over the past thirty years, the importance of human capital investment in the United States has significantly increased leading to a dramatic upward pressure on tuition prices. This dramatic increase in tuition levels has ...
The salience of novel words in speech directed to young children [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
When children begin to learn vocabulary, they tend to learn more nouns than verbs (Goldfield, 1982; Nelson, 1973). Several explanations for this noun bias have been offered. One possibility is that the way nouns are used ...
Photolytically-controlled release of dexamethasone [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Current medical procedures used for repairing bone injuries offer support and stabilization to compromised bones but do not offer a method capable of encouraging bone regeneration. Tissue engineering offers a method of ...
Energy scavenging from the human body for powering prosthetics [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Our research centers on extending battery life of electronic prosthetics by constantly recharging their batteries with energy scavenged from the body. There are many projects in existence where energy has been scavenged ...
