Peptide profiling: Correlating estrogen receptor conformation with biological response
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Chemicals found in the environment have been found to behave like the body's natural estrogen, estradiol. These exogenous estrogen-mimicking compounds have been termed xenoestrogens. Both estradiol and xenoestrogens can ...
Effect of heat stress on sow fertility and health
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
High summer temperatures increase the chance that sow herds will be exposed to heat stress. Heat stress in sows causes a longer weaning to estrus interval, decreased farrowing rates and failure to maintain pregnancy. ...
Characterization of a recombinant inbred line population for quantitative trait locus mapping
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Eukaryotes can regulate gene expression by epigenetic mechanisms at the chromatin level. One epigenetically regulated gene in maize is Pl1-Blotched, an allele of purple plant1, which activates anthocyanin pigment production. ...
Labeling and purification studies on cancer targeting DOTA-TATE labeled with radiolanthanides
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Molecular imaging and targeted radiotherapy are emerging fields for cancer treatment. DOTA-Tyr (3)-Thr(9)-octreotate (DOTA-TATE) is used for peptide receptor-mediated radionuclide therapy (PRMRT) in neuroendocrine tumours. ...
The relationship between childhood obesity and food insecurity: Variations and trends in core literature analyses
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Pediatric obesity is a pressing issue in the United States with recent studies estimating that 17.1% of children ages 2 to 19 years are overweight and an additional 16.5% are at risk of overweight. A landmark case study ...
Axonal regeneration following spinal cord hemi-transection in larval lamprey
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In higher vertebrates, including humans, axonal regeneration following spinal cord injury (SCI) is very limited and there is little behavioral recovery. In contrast, lower vertebrates, such as lamprey, fish, and certain ...
Penetrating the NAT: Why and how?
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Network Address Translators (NATs) that map private addresses to public ones exist between a private computer network and a larger, public domain such as the Internet. The translation of network addresses makes it difficult ...
Effects of even-aged timber harvest on herbaceous vegetation richness in southern Missouri forests
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
For centuries American forests have been exploited for timber and other commodities, often with unforeseen long-term detrimental effects. As areas are cleared, the natural diversity of the forest is altered. Development ...
Seeing through different lenses: How the higher education community views diversity
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Over the years, the societal differences that contribute to the concept of diversity have evolved and expanded. Because of this, the understanding of the term diversity and its implications for higher education vary greatly ...
Roach infestation optimization
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
There are many function optimization algorithms based on the collective behavior of natural systems — Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) are two of the most popular. This poster presents a ...
Microhabitat selection by cave salamander (Eurycea lucifuga) as it relates to relative humidity and temperature
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Depending upon external conditions the twilight region of a cave can vary in temperature and humidity over time. Abundance of cave salamanders was observed to see if they selected for a more suitable microhabitat depending ...
Unexpected exosites on the surface of matrix metalloproteinase-12 that fine-tune specificity for elastin and collagen V
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
MMP-12 hydrolyzes collagens and elastin in normal physiological processes of development, wound repair, and reconstruction of the extracellular matrix. However, chronically elevated levels of MMP-12 activity can sustain ...
Biotope mapping to compare and contrast Columbia, Missouri neighborhoods
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
How people manage their property can ultimately have an affect on biodiversity, and ecosystem services. Our project seeks to understand the relationship of socioeconomic status to property management and how it affects ...
Acadian Flycatcher nest placement: A strategy of survival
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Due to recent population declines, the reproductive success of neotropic migratory birds has become a prime research target. Predator-prey interaction, namely nest predation, has been shown to be the leading cause of nest ...
Determining the structural dynamics of MMP-3/TIMP complex from NMR relaxation
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
MMP-3, or Stromelysin 1, is an proteolytic enzyme of the extracellular matrix that is involved in the repair of wounds. It is implicated in inflammation and cartilage damage and inflammation in rheumatoid arthritis and ...
The impacts of floral fragrances and ant contamination on pollinator behavioral responses
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
World economy, including agriculture and food production, is heavily dependant on animal pollination. For this reason, it is important to understand factors that mediate plant-pollinator interactions. We investigated ...
IPTV: Streaming television over the Internet
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
IPTV is the process of streaming video over a network connection like the internet. This could be the next step in television evolution. There are currently several programs and boxes that you can buy that use the internet ...
Role of Gbx2 expression in cranial nerve V development
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Gbx2 is a member of the Gbx family of homeobox genes that encodes for the transcriptional factors Gbx1 and Gbx2. The amino acid sequence of Gbx2 is highly conserved across multiple species (e.g. mice, zebrafish, chicken, ...
Understanding T regulatory cell development in the thymus using both in vivo and in vitro models
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Multiple sclerosis (MS) is an autoimmune disease caused by autoreactive T cells attacking myelin sheath proteins in nerve fibers of the central nervous system resulting in paralysis and death. Conventional T cells (cytolytic ...
Effects of polyploidy on female call preference in gray treefrogs, Hyla chrysoscelis
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
