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 the development of radio...
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; ...
The effects of an 8-week low-intensity exercise program on people with arthritis
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
This study analyzes the effects of 8 weeks in the PACE program, a low-intensity exercise program for people with arthritis in the areas of pain, stiffness, function, and physical performance. PACE, which stands for People ...
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 ...
Purification and site mutagenesis in GDP-mannose dehydrogenase
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
complications and death in patients, specifically cystic fibrosis patients. This summer's research was centralized on the step in the pathway controlled by the AlgD gene which oxidizes GDP-mannose to GDP-mannuronic acid by the enzyme GDP- mannose dehydrogenase...
What do pink pigs and soybeans have in common? Selecting for mutants in the ureide pathway
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
leaves of the soybean. We were able to isolate several putative PPFM ureide utilization mutants. This research will give insight into the interactions between PPFMs and soybean that may be applied to many other plants. Experiments to recover kanamycin...
From pyruvate to PEP...the unknown pathway
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Soybean is a major crop in the United States. Its survival and relationship with its environment are closely monitored. For example, we are looking at the symbiotic relationship between soybean and the soil bacteria. These ...
Corolla length and autogamy in Nicotiana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Nicotiana has been an interest of study due to its variance in autogamy and floral traits. Species N. plumbaginifolia and N. longiflora are characterized by their difference in flower size and the ability to self pollinate. ...
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 ...
Two-parameter model of cell membrane response to cryoprotectant agents
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
(Gao and Critser, 2004, Biomaterials and Biomedical Engineering). There are several mathematical models of the volume change process including the “two-parameter” model which is used exclusively for this project (Benson et al., 2004). The two...
Silencing of three members of the cytochrome p450 family of genes to uncover their role in iron regulation in A. thaliana
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
a phenotype suggesting that their function may be redundant. Since obtaining a triple mutant plant via crossings of individual KO lines is not achievable due to the three genes being tightly linked, here we employ a RNAi strategy to silence them...
Offspring sex ratio varies with maternal condition in mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Field and laboratory animal studies have demonstrated that maternal body condition can directly cause adjustments in offspring sex ratio. A mother's condition is affected by a variety of environmental and endogenous factors, ...
Therapy of experimental allergic encephalomyelitis under circumstances relevant to human multiple sclerosis
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Experimental allergic encephalomyelitis (EAE) is an inflammatory disease of the central nervous system (CNS) that resembles human multiple sclerosis (MS). EAE and MS develop when proteins of the myelin sheath that covers ...
The effects of oncogenic Ras on the ocular lens
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Ras is a small GTP-binding protein in the signal transduction machinery. In most cell types, activation of Ras by growth factors is essential for normal cell proliferation. A mutation in the Ras gene can lead to a constitutive ...
A multicopy suppressor screen in yeast to look for negative regulators of Ser13 phosphorylation-based trafficking to the pre-vacuolar compartment
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Resident membrane proteins of the yeast trans-Golgi network (TGN) frequently cycle between the TGN and both the early and late (prevacuolar) endosomal compartments. The model yeast TGN protein, A-ALP, which contains the ...
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 can simultaneously monitor...
Expression of aT4g27260/GH3-5/GH3a studied with in situ hybridization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Tropisms, the responses of plants to external stimuli, have been studied as important evolutionary adaptations and as possible areas of future advantageous genetic manipulation. The goal of our current research is to identify targets of NPH4/ARF7...
What's in a worm; Uncovering polymophisms in soybean cyst nematode parasitism genes that correlate with virulence
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
soybean plants. Of particular concern, however, is that genetically diverse field populations of SCN have shown the ability to overcome current sources of resistance. Previous research has confirmed that parasitism genes expressed in esophageal gland cells...
A study of wireless sensor networks with focus on node localization
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Due to research in low-power, cheap wireless communications, Wireless Sensor Networks (WSN) has become one of the most exciting new fields of interest within computer science and engineering. Just as the Internet has made data readily available...
Uranium: The problem, or the solution?
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
is one that the Chemistry Department at MU consistently looks into. One way to better optimize waste extraction is to possibly bind two separate functional groups to uranyl(VI) [UO22+] so that the reactions will occur selectively. The product of interest...
