Examnining the effects of generation level, social class, and parents' level of education on Mexican American college students' outcoume expectation and perceived cultural congruity
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
A survey was conducted with 309 Mexican American college students to assess the effects of college outcome expectancies and perceptions of the university environment. Specifically, we explored differences in generation ...
Camgaroo-2 as an indicator of function in embryonic and neuralized stem cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The transplantation of stem cells to replace cells that have been lost or damaged due to disease or injury is quickly becoming a conceivable treatment method. Embryonic stem (ES) cells have the capacity to become any cell ...
Studying DNA methylation changes of CpG islands in different stages of prostate cancer by pyrosequencing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Prostate cancer is one of the most common forms of cancer in men. Our lab is currently investigating changes in DNA methylation that occur during cancer progression, and in response to the soy phytoestrogen genistein ...
Resource selection of black-footed ferrets based on black-tailed prairie dog distributions
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study investigates how black-footed ferrets (Mustela nigripes) select their habitat in relation to the distribution of black-tailed prairie dogs (Cynomys ludovicianus). Ferrets are one of the rarest and most endangered ...
Making the Cvt pathway/autophagy in vitro
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Autophagy, Greek for “self eating”, occurs in all eukaryotic cells to remove damaged or unwanted organelles or to provide a source of nutrients during starvation. In autophagy, a double membrane surrounds a cluster of ...
From pyruvate to PEP...the unknown pathway
(University of Missouri--Columbia. Office of Undergraduate Research, 2004)
Soybean is a major crop in the United States. Its survival and relationship with its environment are closely monitored. For example, we are looking at the symbiotic relationship between soybean and the soil bacteria. These ...
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 ...
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 ...
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 ...
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)
