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 ...
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. ...
Immigrant women and domestic abuse: Barriers to seeking services [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The experience of an immigrant woman in the United States who has been abused by an intimate partner presents an especially complex legal and social service situation due to her status as an immigrant. Any added complications ...
Modification of a Calcein-based assay for proteolytic activity [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
This investigation was aimed at developing an assay for characterizing samples gathered from tissues on which microvascular permeability studies were being conducted. In particular, we were looking for evidence of proteolytic ...
International media and economic policy: A comparative media analysis of 2002 U.S. steel tariffs [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
This paper compares American and European media coverage of the U.S. Emergency Safeguard Measures for steel which were imposed from March 2002-Dec. 2003 and levied tariffs of up to 30% on some steel imports. Of European ...
On air: Evaluating streaming MPEG4 video performance over wireless networks [Novinger abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
There is not a clear consensus on how open-standard video streaming technologies perform across wireless computer networks. Wireless networking technologies have become nearly ubiquitous, particularly in residential networks, ...
Computational and experimental assessment of public dose from normal research reactor operations [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The Missouri University Research Reactor (MURR) in Columbia, Missouri is interested in the amount of the Argon-41 being produced and released to the environment. The objective of this work is to know what operations within ...
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. ...
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 ...
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 ...
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 ...
Development of a PCR assay to genotype aromatase knockout mice [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The aromatase knockout mouse lacks the gene sequence coding for functional aromatase, a protein that converts androgens into estrogens. Previously, to genotype an aromatase mouse, two separate PCRs were run: #1) Neomycin ...
