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 ...
Water flow sensor for eldercare [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Changes in hygiene habits can be an early indicator of mental and/or physical decline in elders. Since personal hygiene activity accounts for much of the water use in a home, and since much of this activity happens in ...
The effect of aldosterone on fatty acid oxidation in HepG2 cells [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The HepG2 cell line is an immorilized cell line harvested from a human hepatocellular carcinoma. This study is designed to investigate the affect of aldosterone on the mitochondrial function, specifically fatty acid ...
Processing brainwaves for hand-free control of devices [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We have built a system to observe and analyze brainwaves for use in controlling devices such as wheelchairs and electronic prosthetics bypassing a need for the user to have use of their hands and/or other limbs. The system ...
Novel inhibition mechanism and potent antiviral activity of translocation-deficient reverse transcriptase inhibitors [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Nucleoside RT inhibitors (NRTIs) are among the most potent anti-HIV agents and act as chain terminators because they lack a 3'OH. However, this feature can reduce affinity for RT compared to the analogous dNTP substrate, ...
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 ...
Microclimate studies of crop environments under different agroforestry arrangements [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
One of the factors influencing crop yields is evapotranspiration; the evaporation of water from both plants and soil. Soil moisture provides many nutrients to crops, so evapotranspiration rates are of concern. This study ...
Hormonal contraceptive use increases serum 25-hydroxyvitamin D concentrations in active, young women [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Many studies have shown that the estrogen in oral hormonal contraceptives (HC) increases serum 25-hydroxyvitamin D 25(OH)D concentrations in women. As a hormone that regulates gene transcription estrogen is known to increase ...
Traits associated with brace root characters implicate light and hormonal signaling pathways [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Maize brace roots provide the plant with access to water and nutrients in the soil, increase stability, and improve lodging resistance. The goal of this study is to connect brace root traits to traits linked to developmental ...
Determination of the efficacy of an applied vacuum at the skin surface during the laser therapy of Port Wine Stain (PWS) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
We will be doing experiments ex vivo using pig skin, which is very similar and much more attainable than human skin, to test the stress vs. strain relationship, elasticity (Young's Modulus) and research skin mechanics. ...
Impact of effective instruction within middle school classrooms on at-risk student problem behavior [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Teachers are increasingly faced with students who present challenging behavior in the classroom. When faced with such challenges, educators look for effective ways to manage problem behaviors, as well as to prevent problems, ...
Effect of assumptions by pre-service teachers concerning family life, extracurricular involvement and socioeconomic status [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The state of Missouri wants to produce highly qualified educators in order to facilitate high performing students; because of this it is vital that pre-service teachers alter their expectation in order to maintain high ...
Spermatid specific thioredoxin (SPTRX3) as a novel human male infertility marker [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Spermatid Specific Thioredoxin (SPTRX3) is a protein that accumulates in the superfluous cytoplasm of defective human spermatozoa. We researched the relationship between SPTRX3 and male infertility in men from 239 couples ...
Dengue RdRp characterization [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Dengue virus kills 25,000 people annually in affected tropical regions. Non-structural protein 5 of the virus has RNA-dependent-RNA-polymerase and methyltransferase activity in separate domains. Since genome duplication ...
Photoacoustic detection of metastatic melanoma in lymph nodes [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The project's objective is to detect metastatic melanoma cells in lymph node cross sections using a pulsed laser to generate the photoacoustic effect. When melanoma metastasizes it uses the blood stream or the lymphatic ...
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 ...
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 ...
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 ...
Genetic variation associated with adaptive traits in the African forest (Loxodonta cyclotis) and savanna elephant (L. africana) [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
