Co-Option Of The Yolkless Oocyte Receptor For Crispr/Cas9 May Induce Transient Sterility In Female Drosophila Grimshawi Flies, Bronwyn Miller
Co-Option Of The Yolkless Oocyte Receptor For Crispr/Cas9 May Induce Transient Sterility In Female Drosophila Grimshawi Flies, Bronwyn Miller
University of New Orleans Theses and Dissertations
Evolutionary developmental biology has historically used generalist model organisms like Drosophila melanogaster. The Hawaiian Drosophilidae radiation, which occurred just 25 million years ago, is an ideal lineage for work in Evo-Devo. Hawaiian flies make up 25% of the world’s Drosophila species and extreme diversity is seen throughout the group. D. grimshawi is a generalist Hawaiian picture-wing fly that has served as a model for the Hawaiian Drosophilidae radiation. However, D. grimshawi’s power and use as a model organism is constrained by our lack of ability to manipulate its genome. In this work, I attempted to edit the genome of …
The Race To Fifty Feet: An Effort To Determine The Benefits Of Deepening The Mississippi River, Brian Miles
The Race To Fifty Feet: An Effort To Determine The Benefits Of Deepening The Mississippi River, Brian Miles
University of New Orleans Theses and Dissertations
This research examined the benefits and drawbacks of deepening the Lower Mississippi River to fifty feet. It established that the deepening of the Lower Mississippi River will impact not only the local area but also the inland regions that rely on the river systems and lower river ports for product movement. The perspectives of vessel operators, maritime industry experts and charterers are provided to offer insight. The sources for the research include educational literature, maritime research and interviews of industry experts. Based on this research, it is clear that this project will benefit many parties. The beneficiaries will include both …
Having A High-Activity Catechol-O-Methyltransferase Allele Is Associated With Elevated Anxiety And Lower Salivary Dehydroepiandrosterone But Also Lower Alpha Amylase In Children With Chromosome 22q11.2 Deletion Syndrome., Jessie Beebe
University of New Orleans Theses and Dissertations
Chromosome 22q11.2 deletion syndrome (22q11.2DS) results from a hemizygous deletion located on the long arm of chromosome 22. The most common deletion sizes affect between 30 and 90 genes. Individuals with 22q11.2DS may develop serious developmental and psychiatric disorders. The phenotype is highly variable, however, and may be influenced by allelic variation of the retained copies of genes covered by the deletion. I set out to examine the effects of two genes, catechol-O-methyltransferase (COMT) and proline dehydrogenase (PRODH), in relation to anxiety in children and adolescents with 22q11.2DS. Individuals with the major COMT allele (higher activity) have significantly higher anxiety …
