Analysis of the effects of dietary ascorbic acid on a beneficial wasp [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Recent development in genetic engineering has paved the way for researchers to produce crops of high nutritional value, high yield and resistant to diseases and pests. Ascorbic acid is one of the nutrients that researchers ...
Unequal reinforcement values from equally warm and cool temperatures in Drosophila
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Insects inhabit extreme temperature environments and have evolved mechanisms to survive there. When temperatures either rise or fall, small insects alter their behavior within seconds to avoid, in extreme situations, ...
Using geographic information system to address environmental justice concerns in transportation projects
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Environmental Justice concerns were brought up in the county of Cape Girardeau about impacts to the community. These impacts, caused by the construction of a new bridge (crossing the Mississippi River) and the associated ...
Solid phase synthesis of iodinated Dmt-D-Ala-Phe-Orn, a μ-opioid peptide [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
critical step to obtain the necessary building block of the subsequent synthesis of the iodinated peptide. This was done by the use of the reagent bis(pyridine)iodonium tetrafluoroborate to add iodine to dimethyl tyrosine. ...
What role does phosphorylation of cardiac troponin I play in elevating cardiac contractility following adrenergic stimulation?
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Myocardial performance is enhanced when adrenergic receptors are stimulated by catecholamines. The enhanced performance is mediated by cAMP dependent protein kinase A (PKA), which phosphorylates several proteins within the ...
Comparison of the progression of glomerulosclerosis between Oim-C57BL/6 and Oim-B6C3Fe a/a [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Osteogenesis Imperfecta (OI), a heritable connective tissue disorder, resulting from mutations in the type I procollagen genes is characterized by bone deformity and fragility. The OI mouse model (oim) is homozygous for a ...
99mTc-DPR-SSS-BBN for diagnosis of human cancers [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Receptor-specific, radiolabeled peptides have become increasingly popular as targeting vectors for the development of new diagnostic radiopharmaceuticals. The over-expression of certain receptors such as the gastrin releasing ...
Resolution of phylogenetic patterns within the angiosperm order Asparagales [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The angiosperm order Asparagales, is an economically important monocot order that includes onions (Allium), asparagus (Asparagus), and agaves (Agave). The core Asparagales includes ten families that form a monophyletic ...
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 cyst nematode (SCN) is a parasitic worm that penetrates and infects soybean roots resulting in billions of dollars in crop loss annually. The most cost effective and environmentally friendly SCN management strategy ...
Regulation of menaquinone production in Desulfovibrio vulgaris Hildenborough and Desulfovibrio desulfuricans strain G20 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Menaquinones are cytoplasmic membrane components that have important roles in electron transport for energy generation in anaerobic bacteria. A simple and sensitive protocol for the purification and quantification of ...
Characterizing the role of Glycine max NHL gene family members in plant-nematode interactions [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Soybean cyst nematode (SCN; Heterodera glycines) is a microscopic parasitic roundworm of soybean that causes nearly $1 billion dollars in annual yield loss in the United States. SCN damages the plant by attaching itself ...
