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 ...
"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 ...
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 ...
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 ...
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 ...
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 ...
Quantitative trait loci for seminal root angle and number in the maize IBM population
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In maize, seminal roots develop and the primary root system deteriorates as the plant matures. The seminal roots comprise the majority of the root system of the adult plant and give the plant stability against lodging. ...
Characterization of N gene homologs in Nicotiana species
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
We have developed a new variety of Nicotiana, N. edwardsonii var. Columbia, that can be used as a bridge plant to move virus resistance genes from N. glutinosa to N. clevelandii, and have made crosses between N. edwardsonii. ...
Development of conversation in toddlers: The role of maternal input
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
One of the most important human skills is the ability to engage in conversation. This includes our ability to initiate topics, take turns appropriately, and respond contingently to a partner's utterances. While we know ...
Mean value formulas for differential operators
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The main goal of our research is to discuss Mean Value Formulas for solutions of partial differential equations of a certain form (see 1 below) where A is a symmetric, positive definite, real-valued matrix. Such equations ...
