The politics of CO2 emissions
(University of Missouri--Columbia, 2020)
Climate change poses a severe threat to humanity for the last few decades. Various forms of natural disasters, extreme weather events, the outbreak of deadly diseases, life, and food insecurity are among common threats of climate change...
Body size and shape in insular environments and applications of the island rule in biological anthropology
(University of Missouri--Columbia, 2021)
to the mainland. Last, an investigation on the diversity of two human populations in the Baja California peninsula demonstrates that Amerindians who migrated to and survived in these regions were impacted by ecogeographic pressures in different degrees, likely...
Genetic and nutritional effects on reproduction in lactating dairy cows
(University of Missouri--Columbia, 2020)
on the PAG S-N. Cows with the greatest fertility sub-index had greater milk PAG-S-N compared with cows with intermediate and poorest fertility suggesting possibly a more favourable environmental for the establishment, maintenance of pregnancy and fetal...
Effect of bioprotectants on turkey sausage
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.]Food pathogens are of great public health significance, but the spoilage bacteria cause tremendous loss to the food industry. The objective of this study was to determine...
Vitamin D status as a predictor of outcomes of experimentally-induced muscle pain and weakness in young, healthy volunteers
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Vitamin D receptor's presence in skeletal muscle indicates a role in muscle function and clinical symptoms of vitamin D deficiency include muscle weakness and pain. No one has...
Capturing and assessing conceptual change in problem solving
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Many studies have shown that using cognitive conflict strategy, which is a common approach to foster conceptual change, is insufficient to induce change (Alervemann & Hague...
Adenosine deaminase acting on RNA (ADAR1) in the development of abdominal aortic aneurysm and atherosclerosis
(University of Missouri--Columbia, 2021)
mouse and human AAA tissues. 2) Heterozygous knockout of ADAR1 diminishes the Ang II-induced AAA/dissection in ApoE-/- mice. 3) Mouse aortic transplantation indicates that ADAR1 in vascular cells is essential for AAA formation. 4) SMC-specific ADAR1...
Securitization as a theory of media effects : the contest over the framing of political violence
(University of Missouri--Columbia, 2007)
This dissertation proposes a particular form of media framing effect from securitization, a process in which political actors seek to create consensus about security related issues such as terrorism and immigration by ...
The type I IFN of Bos taurus
(University of Missouri--Columbia, 2008)
. The data collected for the second aim revealed the Type I IFN locus has undergone significant rearrangement and expansion in bovine compared to mouse and human. The IFNW subfamily is greatly expanded compared to other species, comprising 24 potentially...
Forage production and diversification for climate-smart tropical and temperate silvopastures
(University of Missouri--Columbia, 2019)
. We examined three distinct silvopastures, two in the country of Panama and one in the state of Missouri, to better understand how the integration of woody perennial trees and shrubs affects forage productivity, availability, and nutritional value...
Investigation of genes involved in somatic embryogenesis and plant-Agrobacterium interactions through transcriptional profiling
(University of Missouri--Columbia, 2021)
Plant genetic engineering relies on the ability to transmit and express cloned DNA sequences in plant cells (transformation) as well as the capacity for the cells carrying this DNA to undergo division and differentiation ...
Phylogenomics of orchids and their mycorrhizal fungi : trees, diversity, and the pursuit of symbiosis
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Phylogenetic trees show us how organisms are related and provide frameworks for studying and testing evolutionary hypotheses. To better understand the evolution of orchids...
Ecological genomics of divergence, admixture, and fitness in the smallmouth bass (Micropterus dolomieu)
(University of Missouri--Columbia, 2021)
their extensive native distribution. Much less is known about levels and distribution of diversity within the species. In 1940, Carl Hubbs and Reeve Bailey published descriptions of two distinct subspecies: the Northern Smallmouth Bass (M. d. dolomieu), inhabiting...
Omputational perspectives of memory storage and gamma oscillation within the amygdala
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Background and motivation: Survival is a key trait seen in all animal species. To survive, it is necessary to have the ability to associate fear responses to new stimuli...
Involvement of aberrant chromosome architecture and locus-specific vulnerability to DNA methylation epimutations in bovine large offspring syndrome
(University of Missouri--Columbia, 2022)
Large/abnormal offspring syndrome (LOS/AOS) and Beckwith-Wiedemann syndrome (BWS) are similar congenital overgrowth syndromes which occur naturally in ruminants and humans, respectively. The incidence of these syndromes increases when offspring...
Characterization of the sporozoite and eythrocytic stages (SES) protein
(University of Missouri--Columbia, 2007)
sporozoite stages, but also during the erythrocytic stages. This novel protein has three conserved regions of unknown function that are present in eight Plasmodium spp. representing human, avian, non-human primate, and rodent malarias. Antibody blocking...
Agroforestry buffer, biomass crop, and grain crop effects on soil quality and soil water use
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soil degradation, impaired water quality, and reduced soil organic carbon have become major concerns in the management of degraded claypan soils with their associated ecological...
Metabolically activated heterocyclic N-oxide compounds for killing and visualizing hypoxic cancer cells
(University of Missouri--Columbia, 2009)
Tirapazamine (TPZ) is currently undergoing a variety of phase I, II, and III clinical trials for the treatment of various human cancers. TPZ derives its medicinal activity by inducing DNA damage in poorly oxygenated tumor cells. Selective...
