Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett
Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett
Theses and Dissertations
Winter hair coat shedding ability in southern U.S. cattle production has previously been associated with differences in adjusted birth and weaning weights of calves from dams that shed by June or later (Gray et al., 2011; Cauble et al., 2019). This study was developed to research possible avenues of why these relationships exist with winter hair coat shedding ability. The primary objectives of the following experiments were to: 1) evaluate how mineral status relates to winter hair coat shedding ability, 2) evaluate how winter hair coat shedding ability relates to apparent digestibility of forage, 3) evaluate winter hair coat shedding …

Bacteria respond to environmental cues through a variety of mechanisms. Two-component systems (TCSs) are a conserved mechanism used by bacteria to accurately respond and sense environmental changes. The monitoring of envelope perturbance is linked to TCS CpxA/CpxR in animal-infecting pathogens. The study of the TCS response regulator (RR) CpxR is largely unexplored in phytopathogens. This work focuses on the genetic linkage between cpxR and T3SS expression regulation. We identified the multiple roles of CpxR on several T3SS regulators and its participation in the bacterial second messenger (c-di-GMP) signaling cascade. Moreover, a compound library screening revealed a novel Cpx inducer CHIR-090, …

Selection And Demography Drive Range-Wide Patterns Of Mhc Variation In Mule Deer (Odocoileus Hemionus), Rachel M. Cook

Variation at functional genes involved in immune response is of increasing concern as wildlife diseases continue to emerge and threaten populations. The amount of standing genetic variation in a population is directly associated with its potential for rapid adaptation to novel environments. For genes in the major histocompatibility complex (MHC), which are crucial in activating the immune response and which have extremely high levels of polymorphism, the genetic variation has been shown to be influenced by both parasite-mediated selection and historical population demography. To better understand the relative roles of parasite-mediated selection and demography on MHC evolution in large populations, …
Assessing The Anticipated Needs Of Transgender Patients In Cancer Genetic Counseling, Jacqueline Baquet
Assessing The Anticipated Needs Of Transgender Patients In Cancer Genetic Counseling, Jacqueline Baquet
Theses and Dissertations
Most cancers are sporadic, but 5-10% of all cancer is hereditary, or caused by a heritable genetic mutation. A patient’s medical history, family history, genetic test results, intact organs (e.g., ovaries) at an increased risk for developing cancer, and the availability and accessibility of interventions are used to make recommendations for cancer-risk management. In addition to basic medical care, transgender patients have healthcare needs that differ from those of cisgender patients such as expert care related to using hormones or having gender-affirming surgery, as well as unique mental health concerns. Transgender individuals may also experience a greater number of barriers …
An Exploration Of The Genetic Counselor’S Role In The Individualized Education Program, Naomi Jean Barker
An Exploration Of The Genetic Counselor’S Role In The Individualized Education Program, Naomi Jean Barker
Theses and Dissertations
Purpose: This exploratory study aimed to assess the knowledge of school psychologists and special education teachers regarding genetic conditions and the resources used in the development of individualized education programs (IEP) for students with genetic disorders. While the IEP process has been described for children with disabilities, literature explicitly focusing on children with genetic conditions is lacking. The rarity of genetic conditions often leaves school personnel with limited information. Methods: School psychologists (N=29) and special education teachers (N =14) throughout the United States participated in an online questionnaire. School psychologists were recruited from research committee listservs of state associations, and …
Efficacy Of Telegenetics: A Diagnostic Yield Comparison Between In-Person And Telemedicine Pediatric Genetic Evaluations, Allie Merrihew
Efficacy Of Telegenetics: A Diagnostic Yield Comparison Between In-Person And Telemedicine Pediatric Genetic Evaluations, Allie Merrihew
Theses and Dissertations
The purpose of this study was to investigate the efficacy of telegenetic services for pediatric genetic evaluations conducted by telemedicine by comparing it to in-person pediatric genetic evaluations. Research into the utility of telegenetics would greatly serve to identify if this is a preferred alternative service delivery model to bridge the gap in accessibility and reach a greater catchment area of the population, especially to those living in underserved and rural locations. This study was a retrospective review of electronic medical records of pediatric patients seen at Greenwood Genetic Center (GGC) for initial in-person genetic visits prior to the COVID-19 …
Exploration Of Patient Communication Preference Regarding Reclassified Genetic Test Results, Cooper Nicole Hall
Exploration Of Patient Communication Preference Regarding Reclassified Genetic Test Results, Cooper Nicole Hall
Theses and Dissertations
Genetic testing is becoming increasingly used to detect individuals who are predisposed to developing cancer. If genetic testing identifies a variant in an individual’s DNA, the testing laboratory uses available data to classify the variant as either disease-causing or benign. When limited data is available regarding a variant’s pathogenicity and the risk of cancer for an individual is not clear, the variant is classified as a “variant of uncertain significance” (VUS). If new data is discovered, the VUS may be reclassified. There is a gap in current literature regarding desired communication for a reclassified genetic test result. There are no …

Reducing Seed Coat Fiber Content And Pod Shatter, And Engineering Medium Chain Fatty Acids-Containing Oil, In The Oilseed Crop Pennycress ( Thlaspi Arvense L. ), Maliheh Esfahanian
Theses and Dissertations
The overall goal of this thesis was to genetically improve agronomic traits of pennycress (Thlaspi arvense L.; Field Pennycress) and demonstrate the production of value-added designer seed oils to domesticate pennycress and enable its establishment as a new winter annual oilseed/meal/cover crop to be grown in temperate regions of the world. In the U.S. Midwest, pennycress can be double cropped on existing farmland during the time between corn harvest and subsequent planting of soybeans the following spring. Pennycress has the potential to produce 2,000 lbs/acre seeds, which at 33% by weight oil content and 20% protein, would yield 85 gallons/acre …
Identifying Genes Downstream Of Mef2 That Influence Ethanol Sedation In Drosophila Melanogaster, Ananya Talikoti
Identifying Genes Downstream Of Mef2 That Influence Ethanol Sedation In Drosophila Melanogaster, Ananya Talikoti
Theses and Dissertations
Alcohol use disorder is a global public health issue that affects millions across the world. It can result in negative physical and mental health outcomes, and currently treatment options are limited and rates of relapse are high. Identifying genes that affect aspects of ethanol behaviors in model organisms, such as Drosophila melanogaster, can serve to eventually develop more robust therapeutic interventions for those experiencing alcohol dependence. Previous studies have identified a relationship between a person's initial sensitivity to alcohol and their abuse potential for the drug in later life. Therefore, we can study sedation behaviors in Drosophila melanogaster to …
