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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Instrumental neutron activation analysis of postclassic and historic-period pottery from Soconusco, Chiapas, Mexico [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
The study involved utilizing Instrumental Neutron Activation Analysis (INAA) at the University of Missouri Research Reactor (MURR) on 96 pottery samples from the post-classic Mayan (ca. 1000-1500 C.E.) and historic eras ...
Stem cells transplanted into the brain are immunogenic and are actively rejected by the host [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Stem cell-based therapies have shown great promise in the treatment of neurodegenerative diseases such as Batten's Disease and Parkinson's Disease. Intracranial stem cell transplantation has the potential to restore function ...
A novel algorithm for semiautomatic brain structure segmentation from MRI [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
On a daily basis, numerous medical institutions use MRI segmentation to conduct research and treat patients. While there are many different segmentation algorithms that exist today, most have drawbacks in respect to either ...
Fourier transforms applied to a hydraulic system [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Control valves (i.e. poppet valves) are commonly used in hydraulic systems for accurate control of the system response. These valves can only provide accurate responses for a limited frequency range. The bode plot is a ...
Media lynching on the campaign trail [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This is a multidisciplinary research project that is about the use of race in political ads from 1988 to 2006. Although the student researcher has analyzed five political ads, only one of the ads, “The Willie Horton” ad, ...
The formation of cysteine-tyrosine crosslinks via a sulfenic acid intermediate [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Cysteine residues in proteins are readily oxidized to sulfenic acids. Sulfenic acids, in turn, can act as potent electrophiles that have been observed to form intrastrand protein crosslinks with neighboring amide or cysteine ...
