Spinal cord injury induces changes in ion channels of reticulospinal neurons in larval lamprey
(University of Missouri--Columbia, 2008)
After spinal cord injury in larval lamprey, RS neurons regenerate their axons (Davis and McClellan, 1994a,b), restore synaptic contacts and most of the original locomotor functions (McClellan, 1998). It was previously ...
Effects of riparian buffer width on stream salamander populations in the southern Appalachian Mountains
(University of Missouri--Columbia, 2008)
Salamanders in the Appalachian region have been extensively studied, but the majority of research assessing the impacts of logging has focused on terrestrial species that are not dependent on stream habitats for egg ...
Heterochrony of floral and mating system characters between Nicotiana longiflora and N. plumbaginifolia
(University of Missouri--Columbia, 2007)
The evolution of selfing is one the most fascinating and common trends observed in flowering plants. Selfing flowers are often smaller than their outcrossing relatives, with reduced reproductive effort. The selfing species ...
Effects and interactions of endocrine disrupting chemicals and diet on the mouse reproductive system
(University of Missouri--Columbia, 2007)
Recent studies have indicated that a number of ubiquitous chemicals found in the environment are linked to a myriad of health concerns, including reproductive abnormalities and increases in infertility, cancer, and obesity ...
Gray treefrog breeding site selection and offspring performance in response to forest management
(University of Missouri--Columbia, 2007)
Amphibian diversity and abundance are generally reduced following clearcut logging. These impacts often last for decades, but little is known about why diversity and abundance are depressed. I examined gray treefrog breeding ...
The effects of histone acetylation on the maize allele PL1-blotched
(University of Missouri--Columbia, 2007)
Covalent modifications of DNA and nucleosomal histone proteins associated with eukaryotic chromatin have the potential to alter expression of a gene without change in its DNA sequence. One gene regulated through this ...
Bat avoidance in the katydid genus Neoconocephalus
(University of Missouri--Columbia, 2010)
The hearing system of the katydid genus Neoconocephalus has two functions: intraspecific communication and predator (bat) avoidance. Male calls and bat cries differ spectrally and temporally. Katydids must recognize and ...
Pollen-pistil interactions in nicotiana
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] To screen for potential mates, angiosperm pistils provide a physical and biochemical barrier that promotes the growth of desirable pollen while ...
Regulation of plant development in Arabidopsis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The development of a complex organism, such as a plant, requires the function of multiple pathways that regulate various aspects of the developmental ...
Characterization of an in vitro neural stem cell niche with educational component : stem cells and society
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] We describe a novel neural stem cell (NSC) culture system, derived from embryonic stem (ES) cells, that maintains and expands a population of neural ...
From developmental biology to tissue-engineering: printing blood vessels
(University of Missouri--Columbia, 2009)
Cardiovascular disease is a leading cause of death and often requires vascular reconstruction. However, the use of synthetic materials and scaffold-based approaches has shown several limitations for small-diameter blood ...
Cellular behaviors regulating tangential migration of facial branchiomotor neurons in the zebrafish embryo
(University of Missouri--Columbia, 2009)
Development of the nervous system is characterized by intricate processes like neuronal migration, axon outgrowth and guidance and synaptic connections to their targets. These processes involve navigation of the migrating ...
Understanding genomic evolution and segregation distortion in solanaceae : a COSII linkage map in Nicotiana
(University of Missouri--Columbia, 2009)
Genetic linkage maps are excellent tools to investigate genomic evolution, genomic structure and quantitative trait loci. In our study, we created comparative linkage maps in a reciprocal cross between Nicotiana longiflora ...
Collective offspring-parent signaling in a social treehopper : mechanisms, patterns and function
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] I investigated the properties of collective behavior in a group-living insect, including the patterns of group behavior, the function of group level ...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
Tumor-initiating cells in malignant brain tumors
(University of Missouri--Columbia, 2009)
Stem cells have the unique ability to differentiate into the many specialized cells of the body. During adulthood, stem cells remain in the organism and maintain the ability to repair and replenish injured or dead cells ...
In vitro and in vivo approaches to tumor targeting by phage display
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Approximately 30% of breast cancers are linked with the over-expression of ErbB2. Because of its critical role in signal transduction, the progression ...
SIRT1 deacetylation regulates NFAT transcriptional activity
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The class III histone deacetylase SIRT1 plays important roles in aging, metabolism and biological clock control. We have recently demonstrated that ...
