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 effects of oncogenic Ras on the ocular lens
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Ras is a small GTP-binding protein in the signal transduction machinery. In most cell types, activation of Ras by growth factors is essential for normal cell proliferation. A mutation in the Ras gene can lead to a constitutive ...
Production of nano particles
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Nano particles (particles having diameters in the nanometer range) have applications in a variety of areas including medical, environmental, sensor, to name a few. However, the production of nano particles having uniform ...
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 ...
Modeling friction stir welding of Al 2024-T3 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2007)
Friction stir welding (FSW) is a modification of the traditional friction welding. It is a process patented by The Welding Institute in Cambridge, England in 1991. It is a mechanical process whereby solid-state welding ...
MCP-1 and its role in lyme arthritis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Lyme disease is caused by infection with the bacteria Borrelia burgdorferi, causing arthritis and carditis in infected animal models. The presence of spirochetes in the joint and other soft tissues induce recruitment of ...
Efficacy of modified constraint-induced movement therapy (mCIMT) protocol with clients with chronic stroke [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Objective: To determine efficacy of a new modified constraint - induced movement therapy protocol in clients with chronic stroke. Method: Each participant will undergo a six week modified constraint-induced movement (mCIMT) ...
Natural variation in phenotypes associated with phototropins among geographically isolated populations of Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
In Arabidopsis thaliana several phenotypes are controlled by blue light including chloroplast relocation movements and bending of the seedling stem in phototropism. These responses are controlled by the phototropins, phot1 ...
Electrohydrodynamic conduction pump - An experimental investigation [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Electrohydrodynamic pumps (EHD) were built and tested to further understand the nature of the technology. Two pumps built used a conductive pumping action to achieve flow within a dielectric fluid. The first pump (pump 11) ...
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 ...
