Identification of chloroplast DNA insertions in nuclear chromosomes of maize B73 line using the FISH procedure
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It is known that chloroplast DNA can incorporate itself into the nuclear genome of plants. However, the sites of chloroplast (ct) DNA integration into chromosomes of maize have not yet been analyzed. This project is the ...
The psychosocial response to lymphedema
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Lymphedema, a life-altering disease, affects many breast cancer survivors throughout the world. Manifested as either an acute or chronic illness, lymphedema can occur at any time during and following post-breast cancer ...
The effects of even-aged cutting on density and pairing success of Worm-eating Warblers
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
It is important for researchers to be aware of how timber management practices affect songbird populations. Certain forest management techniques can cause declines in breeding habitat of Neotropical migrant songbirds that ...
Point mutation of an RGD sequence in the human P2Y2 receptor to a QGD sequence conserves Go-mediated signal transduction
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The P2Y2 nucleotide receptor is a Go/q coupled receptor that is activated equipotently by extracellular nucleotides such as ATP or UTP and is upregulated in a variety of tissues in response to injury or stress. The biological ...
The role of Periostin in regulating the biomechanical properties of cushion tissue
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
During embryonic heart development the atrio-ventricular (AV) cushions swell and fuse to form the valves and septa of the adult heart. Initially, the cushions appear as swellings on the interior wall of the AV canal and ...
Molecular free volume and viscosity changes in non-Newtonian fluids probed with molecular rotors
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
An empirical relationship between molecular free volume and viscosity has been established (Doolittle AK, J Appl. Phys. 1952; 23: 236-9). Non-Newtonian fluids hold much importance to scientific study because of their ...
Issues with scale using very high resolution digital aerial photographs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study involves the use of remote sensing equipment to observe plant communities. A remote sensor is any instrument that gathers information about an object or area from a distance. Advanced cameras, the most common ...
Localized adherence of Haemophilus influenzae to human lung cells in tissue culture
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The gram-negative coccobacillus H. influenzae is part of the respiratory mucosal flora of most healthy humans. Before the era of Hib vaccination, encapsulated H. influenzae of serotype b were the leading cause of childhood ...
Expression, purification and initial characterization of Halobacterium proline dehydrogenase
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Nature recycles proline by converting it to glutamate. This 4-electron oxidation process is catalyzed by two catabolic enzymes, proline dehydrogenase (PRODH) and Δ1-pyrroline-5-carboxylate dehydrogenase (P5CDH). Inborn ...
Anti-galectin-3 peptides increase apoptosis in galectin-3 expressing human breast cancer cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
A critical factor in the proliferation and the metastatic nature of carcinoma cells appears to be their resistance to natural programmed cell death (apoptosis). However, the molecular mechanisms that enable carcinoma cells ...
Reduction of rheniumV oxo Schiff base complexes with triethylphosphine
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Pioneering techniques for therapeutic treatment of cancers involve targeting cancer sites with strong beta-emitting radionuclides, thereby destroying the cancer cells. This is achieved by coordinating the radioisotope to ...
Promotion of functional heterotrimeric type I collagen via transfection in osteogenesis imperfecta fibroblasts
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Osteogenesis imperfecta (OI) is a heritable disorder due to mutations in type I collagen. Normal type I collagen forms a heterotrimeric protein comprised of two pro1(I) chains and one pro2(I) chain [1(I)22(I)]. The ...
Detection of Sad genes in various species of Neurospora
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Neurospora crassa is a haploid fungus that reproduces asexually during vegetative growth. However, in a nitrogen deficient environment, the two mating-type cells, A and a, can fuse together and enter the sexual cycle. ...
Reduction of rhenium (V) oxo Schiff Base Complexes with triphenyl phosphine ligands
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
One approach to the treatment of cancer is to direct beta-emitting radionuclide to the cancer site where the radiation destroys the cancer cells. This can be achieved by coordinating the radioisotope in a very stable ...
"Either he was too weak, or the world was too strong" : motifs of male wounds and healing in African American literature
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
African American men throughout history have tried to establish and define their identities, collectively and individually, beyond those formed, forced, and fashioned by western civilization. Consequently, they have inflicted ...
Synthesis and binding studies of novel sigma receptor ligands
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Sigma receptors are binding sites that are found in the brain, in the endocrine and immune systems, and also in the lungs, kidneys, intestines, muscles and especially the liver. They are classified into two subtypes, sigma1 ...
Stroke risk factors and awareness study
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Cerebrovascular Accidents, also known as strokes, are the third leading cause of death in the United States. It is estimated that more than 275,000 people die from strokes every year (American Heart Association 2003). In ...
How the revolutionary thought of two West Indian intellectuals predicts and explains post-independence African problems
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Though most of Africa gained independence from European colonial rule by 1960, today the continent is still plagued by poverty, ignorance, corruption, internal conflict, and external control. These results are now clear ...
