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, ...
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 ...
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 ...
Stem cells transplanted into the brain are immunogenic and are actively rejected by the host [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Stem cell-based therapies have shown great promise in the treatment of neurodegenerative diseases such as Batten's Disease and Parkinson's Disease. Intracranial stem cell transplantation has the potential to restore function ...
A novel algorithm for semiautomatic brain structure segmentation from MRI [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
On a daily basis, numerous medical institutions use MRI segmentation to conduct research and treat patients. While there are many different segmentation algorithms that exist today, most have drawbacks in respect to either ...
Fourier transforms applied to a hydraulic system [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Control valves (i.e. poppet valves) are commonly used in hydraulic systems for accurate control of the system response. These valves can only provide accurate responses for a limited frequency range. The bode plot is a ...
Media lynching on the campaign trail [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This is a multidisciplinary research project that is about the use of race in political ads from 1988 to 2006. Although the student researcher has analyzed five political ads, only one of the ads, “The Willie Horton” ad, ...
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 ...
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, ...
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 ...
Electric arc production of nanoparticles for energetic materials [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Thermites are a class of energetic material (similar to explosives) which consists of a fuel and oxidizer which react chemically to release energy. These materials are of interest because they can contain over 2.5 times ...
The role of gender in the peer review process of formal writing [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
