Characterization of the mechanism of action of the ultra-potent HIV inhibitor 4'-Ethynyl-2-Fluoro-2'-Deoxyadenosine [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Retroviruses rely on the enzyme reverse transcriptase (RT) to perform the reverse transcription of its genome from single-stranded RNA into double-stranded DNA, which can then be integrated into the host's genome by the ...
Ga-Ga over 68Ga: Novel chelates for PET heart imaging [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Heart disease remains one of the leading causes of death in the United States. Improved, function-specific imaging agents promise to augment current diagnostic techniques, leading to better treatment and fewer deaths. ...
Expression and proteolytic cleavage of Lav, a putative virulence autotransporter of nontypeable Haemophilus influenzae [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Haemophilus influenzae, a gram negative coccobacillus, is part of the normal flora of the human upper respiratory tract. Unencapsulated (nontypeable) strains of H. influenzae (NTHi) cause pneumonia, sinusitis, and otitis ...
Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Molybdenum-99 (Mo-99) is used to create Tc-99, a widely used nuclear medicine diagnostic imaging radioisotope. In an attempt to decrease the need for imported Mo-99, development of mechanical systems to efficiently prepare ...
Identification and deconvolution of overlapped peaks derived from raw 2D PAGE images [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
A standard approach for the analytical separation of proteins in the field of proteomics is the use of two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), which separates a complex crude protein samples from a ...
Using Fluorescence in situ hybridization to study maize lines genetically predicted to have chromosomal abnormalities [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Since the 1960s, genetic evidence has indicated chromosome damage and nondisjunction in lines of maize containing knob heterochromatin-bearing chromosomes and at least two B chromosomes. However, at that time researchers ...
Evaluation of a ferroelectric cathode for use in electric propulsion [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Electric propulsion is used to keep communication satellites in the proper position relative to Earth and for propulsion on deep space probes. One part of the propulsion system, the cathode, is required for the neutralization ...
Surface modification of hydroxyapatite particles for biomaterial applications [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The interface between a filler material and a matrix can have a substantial impact on the properties of composites. This is especially true of nanoscale materials due to their increased ratio of surface area to mass. The ...
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 ...
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. ...
An analysis of wireless security in Columbia, MO [Harper - abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The current state of wireless security in most areas can be estimated based on trends and collected data, but the complete picture is often unknown. Without collecting the information on most wireless access points in a ...
High surface area carbon based batteries [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Lead acid batteries have some flaws that prevent them from being used in applications such as electric vehicles. Their low energy densities, problems with corrosion, sulfation, and inability to withstand deep discharges ...
Survey on vocal fatigue in classroom teachers: Profile based on teaching level [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Voice production is a complex task involving coordination of several systems in our body. Voice plays a crucial role in speech production. Without voice, speech will be inaudible. Voice problems hinder communication ...
Thermal performance maps for forced air cooling of ruggedized electronics enclosures [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Based on standard commercial form factors, this study explores chassis-level air cooling limits for ruggedized military electronics constrained by pressure drop requirements and fin manufacturing capabilities. Numeric and ...
Modeling a gas puff z-pinch as an RL circuit load [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
A Z-pinch is process through which current is passed though a column of plasma and the resultant JxB force acts to "pinch" the plasma to smaller and smaller radii. More specifically, a gas puff Z-pinch is a Z-pinch that ...
Effects of exercise on bone parameters in the oim mouse model [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Previous studies have shown that mechanical loading on the skeleton acts as an anabolic stimulus, including changes in bone geometry, bone mineral density, and mechanical properties. Increases in these properties may improve ...
Domain specific interaction of S-RNase binding protein with the stylar 120 kDA glycoprotein in nicotiana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Through the process of evolution, many flowering plants have developed a biochemical mechanism to prevent self-pollination and pollination by closely related plants. Gametophytic self-incompatibility (SI) is one such system ...
Factors affecting long-term counts of drumming ruffed grouse in Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Ruffed grouse were nearly extirpated in Missouri during the early 1900's because of habitat loss but several populations were re-established by reintroductions. The number of drumming-male grouse has been surveyed on the ...
Do young children recognize the sound system of their native language? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
