An Evaluation Of Bovine Reproductive Function From The Microrna Expression In The Female To Performance Testing In The Male, Erin Amiss
All Theses
Reproductive function is crucial to the success of a beef or dairy herd. Both the female and male play significant roles in the outcome of bovine reproduction. The bull contributes to reproductive success in many ways, such as genetics. The initial role that the bull has in reproductive success is fertilization, whether natural or by artificial insemination. One method of assessing bull performance are central bull test stations, which are traditionally administered by a university, extension center, or are privately owned. Central bull tests assess the performance of bulls from various management systems, breeds, and ages. Some measurements taken during …
Using Cytoplasmic Biopsies To Determine Bovine Oocyte Quality, Madison Lindsey
Using Cytoplasmic Biopsies To Determine Bovine Oocyte Quality, Madison Lindsey
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Embryos resulting from assisted reproductive technologies, such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), develop with lower efficiencies than embryos resulting from their in vivo counterparts. The reasons behind the developmental discrepancies remain largely unknown. Because the egg is the primary determinant of embryo developmental success, it is reasonable to consider inherent egg quality as a possible cause. The hypothesis for this project is that there are distinct mRNA transcript patterns, or molecular “fingerprints,” that distinguish high- versus low-quality eggs developing within the same environment. In this study, a small cytoplasmic biopsy was removed from 40 eggs …
Liquid Chromatography With Tandem Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Symone T. Whalin
Liquid Chromatography With Tandem Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Symone T. Whalin
Masters Theses & Specialist Projects
Bovine mastitis, caused by a wide array of pathogens, results in a substantial economic loss for the dairy cattle livestock industry. β-defensins are a part of the bovine’s innate immune system and act as the first line of defense against mastitis. Only foundational research has been done on β-defensins’ ability to treat and prevent mastitis. There have been no analytical methods reported in the literature for analyzing β-defensins in bovine milk. This research aims to create an analytical approach to determine β-defensins in bovine milk. It is challenging to determine an analyte in a complex sample matrix, and milk is …
Wc1 And Tcr Interactions For Γδ T Cell Activation, Alexandria Gillespie
Wc1 And Tcr Interactions For Γδ T Cell Activation, Alexandria Gillespie
Doctoral Dissertations
Major subpopulations of gamma delta T cells within ruminant and pigs are defined by expression of WC1, a hybrid pattern recognition receptor/co-receptor to the T cell receptor (TCR). It is known that when WC1 is knocked down cells fail to respond. Showing that WC1 plays an active role in the stimulation of bovine gamma delta T cells. Here we explored the spatio-temporal dynamics of WC1 and TCR interaction using imaging flow cytometry and stochastic optical reconstruction microscopy. We found that in quiescent gamma delta T cells both WC1 and TCR existed in separate protein domains (protein islands) but after activation …
