An analysis of aspartic peptidases expressed by trophoblasts and placenta of even-toed ungulates
(University of Missouri--Columbia, 2008)The Pregnancy Associated Glycoproteins (PAGs) represent a multigene family of trophoblast expressed proteins, found exclusively in the placenta of even-toed mammals such as ruminants (cattle, sheep), pig, etc. In ruminants, ... -
Analysis of Gbx genes during neural development
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The understanding of how transcription factors regulate neural patterning in the anterior hindbrain, and how the assembly of specific neuronal circuits ... -
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 ... -
Applying effective energy concept for intake prediction and balancing ruminal nitrogen and post-ruminal amino acid requirements for beef cattle
(University of Missouri--Columbia, 2013)Proper animal nutrition involves balancing nutrient supply to nutrient requirement. Accurate intake prediction is fundamental to diet formulation and appears simple but has historically been challenging to accomplish. ... -
Autophagy and ubiquitin-proteasome system during post-fertilization sperm mitophagy
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Maternal inheritance of mitochondria and mitochondrial DNA (mtDNA) is a universal principle in developmental biology. Mammalian sperm-borne mitochondria ... -
Barriers and values of moral distress among critical care nurses /
(University of Missouri--Columbia, 2016)This dissertation explores the presence of moral distress and effective interventions to lessen its impact on critical care nurses. Manuscript one was completed prior to entering the doctor of philosophy in nursing program ... -
Biological characteristics of Katahdin sheep selected for footrot resistance
(University of Missouri--Columbia, 2014)The objectives of this study were to select sheep divergent for a footrot resistant genotype by screening with the DQA2 gene marker and to investigate the host resistant immune response, neutrophil phagocytic efficiency, ... -
Biological role of conceptus derived factors during early pregnancy in ruminants
(University of Missouri--Columbia, 2016)In cycling domestic animals, pregnancy loss during early gestation is a major cause of infertility. The majority of pregnancy loss during this time is due to errors in mitotic division early in development, or occurs later ... -
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the ... -
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the ... -
Characterization of interleukin-1 beta 2, a novel interleukin-1 expressed by the early pig conceptus during establishment of pregnancy
(University of Missouri--Columbia, 2014)It is essential that the early mammalian embryo attaches to the uterus or implants to survive. Most embryonic mortality is associated with complications during this process resulting in a loss of 25-60% of embryos or ... -
Characterization of progesterone receptor (PGR) mRNA and protein isoforms in the endometrium of cyclic and pregnant pigs
(University of Missouri--Columbia, 2010)Disappearance of the progesterone receptor (PGR) from the uterine luminal epithelium (LE) is essential for cyclicity and pregnancy in pigs. In humans, three PGR mRNA isoforms (PGR-A, PGR-B and PGR-C) arise from alternative ... -
Comparison of rumen microbe taxa among wild and domestic ruminants
(University of Missouri--Columbia, 2015)Microbes that inhabit the rumen provide a diverse set of enzymes that degrade ingested plant material. Without microbes, ruminants could not survive. Our research has focused on identifying microbial taxa associated with ... -
Comprehensive approach to dietary inclusion of high oleic soybean oil in monogastrics
(University of Missouri--Columbia, 2020)The banning of partially hydrogenated oils in food processing by the FDA has led to a search for alternative oil sources with a decreased potential for oxidation. While marketed and founded for use in the food industry, ... -
Determining the efficacy of a biosensor to detect calpastatin, a meat tenderness indicator
(University of Missouri--Columbia, 2007)An instrumental tenderness detection system used at the time of grading to sort beef carcasses on their predicted tenderness would be valuable for the beef industry. A biosensor to accurately predict calpastatin, the ... -
Development of a novel immunoassay for simultaneous quantification of endocrine parameters
(University of Missouri--Columbia, 2015)Since the advent of the radioimmunoassay in the 1950s, numerous immunologically-based methods have evolved for sample analysis. Although each immunological method possesses unique assets and liabilities, all share limited ... -
Differential gene and protein expression in pig nuclear transfer extraembryonic membranes and blastocyst stage embryos
(University of Missouri--Columbia, 2010)Nuclear transfer (cloning) is the process of transferring a donor cell nucleus into an enucleated oocyte. The oocyte and donor cell are subsequently fused and activated to allow for nuclear reprogramming and continued ... -
Digestible amino acid requirements for young female turkeys
(University of Missouri--Columbia, 2018)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Nine experiments were conducted to determine the optimal digestible isoleucine (dIle), valine (dVal), leucine (dLeu), phenylalanine plus tyrosine (dPT) ... -
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) ... -
DNA methylation in the early porcine embryo
(University of Missouri--Columbia, 2007)Reproductive technologies such as in vitro fertilization, intracytoplasmic sperm injection, parthenogenetic activation, and somatic cell nuclear transfer are powerful procedures in the production of animals for agriculture, ...
