Hormonal regulation of bone health: novel understandings of xenoestrogens and estrogen receptor-[alpha]
(University of Missouri--Columbia, 2020)
Estrogen is one of the most influential hormones on bone growth and maintenance throughout the life cycle in both men and women, but there are still unknown roles of estrogen and the estrogen receptors in males. In addition, ...

(University of Missouri--Columbia, 2021)
near infrared spectroscopy. The objective of this study was to examine nitrogen mobilization from a mapping population from the cross PI 361103 (contains high shoot N content and low seed N content) x PI 567572B (contains high seed N content and low...
Studies on the physical properties and preservation of the North American pawpaw (Asimina triloba) fruit
(University of Missouri--Columbia, 2023)
regions of the world. The fruit is native to the United States and grows in over 30 states in the United States including Missouri, Indiana, Ohio, Illinois, and parts of Texas. The fruit has remained underutilized and uncommercialized for several centuries...
Motivation for smoking and smoking cessation : a self-determination theory investigation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nicotine dependence is conceptualized as a disorder of motivation. Initial drug use is goal-directed, but with the development of dependence it becomes increasingly routinized...
Characterization of skeletal muscle in mouse models of osteogenesis imperfecta and myostatin deficiency
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Osteogenesis imperfecta (OI) is a heritable connective tissue disorder hallmarked by bone fragility resulting primarily from mutations in the pro[alpha]1(I) or pro[alpha]2(I...
Biomass production of five populus clones, soil carbon and soil water content in a central Missouri floodplain
(University of Missouri--Columbia, 2006)
Five Populus clones in two short rotation 5 year plantations were tested for biomass production and associated soil C changes in the central Missouri floodplain under climatic conditions of the Midwest. A Populus deltoides x Populus nigra (Eugenei...
Skeletal muscle weakness and mitochondrial dysfunction in the osteogenesis imperfecta murine (oim) model
(University of Missouri--Columbia, 2021)
Osteogenesis imperfecta (OI), also commonly referred to as brittle bone disease, is a heritable connective tissue disorder occurring in roughly 1:15,000 births. OI arises as a result of mutations in the type I collagen ...
Applications of ancestry estimation in cattle population genetics
(University of Missouri--Columbia, 2019)
Accounting for ancestry and cryptic population structure is important in population genetic data analysis. The estimation of ancestry can help elucidate the effects of admixture or stratification on allele and genotype ...
Birth order and gender : differential parental investment in Medieval England and France in the eleventh, twelfth, and thirteenth centuries
(University of Missouri--Columbia, 2020)
This dissertation addresses the question: will parents invest differently in their children based on gender and birth order? Using parental investment theory and four major sets of outcome variables--child survival, parental ...
Digestible lysine and threonine requirements of male turkeys and their effects on performance of male turkeys fed practical diets to market age
(University of Missouri--Columbia, 2008)
Seven experiments were conducted to determine the minimum requirements of digestible lysine (dLys) and digestible threonine (dThr) from 1 to 21 weeks of age for male turkeys. Requirement values were similar to NRC (1994) ...
The antioxidative effects of exercise training-and diet-induced weight loss
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Obesity and insulin resistance (IR) increase the risk for coronary heart disease (CHD); however, much of this risk is not attributable to traditional risk factors. Elevated...
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
Several agricultural management practices such as terrace construction, cover crops (CC), drainage water recycling (DWR), free drainage (FD), and 4R nitrogen (N) management can influence water quality, soil properties, and crop production...
Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
