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 ...
Functional analysis of conserved amino acid residues in the C-terminus of ACC synthase
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Ethylene is an important plant hormone that regulates growth, development, and stress response. Synthesis of Ethylene from its immediate precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), is catalyzed by ACC oxidase. ...
Dissection of plant Pol III transcription machinery in Arabidopsis thaliana [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Our current understanding of RNA polymerase III (Pol III) transcription machinery and its regulation is based mostly on studies in yeasts and vertebrates. In contrast, the knowledge about plant Pol III transcription machinery ...
Novel genetic screen for iron homeostasis in Arabidopsis [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Very little is known about the molecular genetics of iron homeostasis in plants. Using the model organism Arabidopsis, our objective is to identify additional genes involved in iron homeostasis using a novel genetic screen. ...
Atomic force microscopy measurements of topography and friction on dotriacontane films absorbed on a SiO2 surface [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
We report comprehensive atomic force microscopy (AFM) measurements of the nanoscale topography and lateral friction on the surface of thin films of an intermediate-length normal alkane, dotriacontane, at room temperature. ...
Optical imaging technique for viewing apoptotic cells [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The study of programmed cell death or apoptosis in tumors has attracted increased interests. Recent research has shown that whether a cell lives or dies is related to its three dimensional environment such as the organization of cells...
A search for regulators of a yeast synaptojanin
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
activity in membrane trafficking in humans, any further research in the field would be beneficial to human health....
Lobeline antagonizes the discriminative stimulus properties of cocaine
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
that did not generalize to cocaine decreased responding on the cocaine-paired levers. Surprisingly, lobeline did not alter the discriminative stimulus properties of amphetamine. This research further supports the supposition that nicotine, cocaine...
Efficacy of high levels of microbial phytase in improving phytate Phosphorus utilization by turkeys
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
poults each. A National Research Council (NRC) corn-soybean meal diet, adequate in all nutrients, was fed to all birds for the first week. Dietary treatments fed from 8 to 21 days of age included: 1) a positive control NRC diet (0.6% non...
Effects of forest management practices on treefrog oviposition site choice
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
—were implemented at four wetlands at the Savannah River Site. In May 2005, we placed wading pools 25 m into each treatment and allowed them to fill with rainwater. To monitor time to first oviposition event and to determine the number of events per treatment, pools...
The evolving technology of bio-printing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Bio-printing is a novel method of tissue engineering that uses living cell spheroids as the 'bio-ink' and biocompatible gels as the 'bio-paper' with a three dimensional printer that deposits these aggregates into the gel ...
Imaging reticulospinal neurons in the lamprey brainstem using calcium indicator
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Imaging reticulospinal neurons in the lamprey brainstem using calcium indicator In the lamprey, a lower vertebrate, reticulospinal (RS) neurons in the brain are the output elements of the command system that activate spinal ...
Developing proteomics approaches for identifying new, redox-regulated proteins
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
For many years it was thought that hydrogen peroxide was only a toxic substance to cells. However, recent work has revealed that hydrogen peroxide can be utilized by organisms as a cellular signaling molecule. Hydrogen ...
Effects of prenatal exposure to xenobiotic estrogen and the development of endometriosis in adulthood
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Endometriosis is an estrogen-dependent disease that affects millions of women worldwide, causing pain and infertility. While it is known that retrograde menstruation places endometrial tissue in the peritoneal cavity, it ...
Construction of a tatA Desulfovibrio vulgaris Hildenborough
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
tatA Desulfovibrio vulgaris Hildenborough is a member of the obligately anaerobic bacteria growing by sulfate respiration and involved in environmental biocorrosion of ferrous metals. It also shows potential for bioremediation ...
Free energy profile of sugar transport through maltoporin of Escherichia Coli
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The purpose of my project is to investigate molecular (glucose and maltodextrin) transport in the sugar selective, highly asymmetric maltoporin (LamB) outer membrane channel from E. coli by employing all atom molecular ...
Modeling the flow of digesta through the ruminant reticulorumen
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Ruminants possess a specialized gastrointestinal (GI) tract that enables them to efficiently digest fibrous feeds. The first stomach compartment of the ruminant GI tract, the reticulorumen (RR), is the site of most fiber ...
Morphology and cytoskeletal elements of reticulospinal neurons of lampreys in cell culture [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
of growth cones of lamprey RS neurons in cell culture. Our research thus far has been focused on determining the molecular and cellular mechanism in which the lamprey uses for neurite regeneration. This research will give more insight into the structural...
Conversion of waste corncob to activated carbon for use of methane storage
