Ncrna-Protein Interaction Prediction Using Language-Based Features, Krishna Shah
Ncrna-Protein Interaction Prediction Using Language-Based Features, Krishna Shah
University of New Orleans Theses and Dissertations
Noncoding RNAs (ncRNAs) play a significant role in several fundamental biological processes by binding to RNA-binding proteins (RBPs); hence, it is necessary to study ncRNA-protein interaction (RPI). Several classic and deep-learning machine learning models have been pro-posed to predict RPI. These models first need to collect features of RNA and protein, such as physicochemical properties, secondary and tertiary structure, et cetera, before feeding them into the model. More recently, after the advancement of high throughput sequenc-ing and the improvement in Natural Language Processing (NLP), transformer models like BERT-RBP and Evolutionary Scaling Model (ESM) can be trained to automatically extract feature …
Environmental Sensitivity Of Maternal And Offspring Phenotype In The Green Anole (Anolis Carolinensis) Lizard, Jamie Marks
Environmental Sensitivity Of Maternal And Offspring Phenotype In The Green Anole (Anolis Carolinensis) Lizard, Jamie Marks
University of New Orleans Theses and Dissertations
Animals dynamically invest their acquired energetic resources into fitness-related traits, and life-history trade-offs occur when limited resources are invested in a given trait at the expense of another. The phenotypic effects of life history trade-offs are well documented, but the mechanisms facilitating these trade-offs are poorly understood. One such mechanism is the insulin/insulin-like signaling (IIS) network, and specifically its two primary hormones: insulin-like growth factor 1 (IGF1) and insulin-like growth factor 2 (IGF2). IGF1 is well-characterized but IGF2 is severely understudied, though it is present in nearly all amniotes and sometimes expressed at higher levels than IGF1 in adulthood. I …
Chromosome Number Evolution, Phylogeography, And The Effects Of Climate Change On Species Distributions In Polyploid Plant Systems, Courtney H. Babin
Chromosome Number Evolution, Phylogeography, And The Effects Of Climate Change On Species Distributions In Polyploid Plant Systems, Courtney H. Babin
University of New Orleans Theses and Dissertations
Polyploidy, a term used to describe organisms with cells having more than two paired sets of chromosomes, is a significant driver of diversification among land plants. Over a century of research has advanced our understanding of polyploidization in some taxa, but polyploid organisms remain understudied. In this dissertation, I investigate chromosome number evolution, phylogeographic structure, genetic differentiation, and the effects of climate change on ploidy level distribution using polyploid plant systems. In the first chapter, I inferred a molecular phylogeny of Allium, an economically important genus that includes cultivated crops and ornamentals, to investigate evolutionary transitions in chromosome number …
Evaluating Methods To Determine The Maximum Oxygen Consumption By The Gulf Killifish, Fundulus Grandis, Sylvia Mullen
Evaluating Methods To Determine The Maximum Oxygen Consumption By The Gulf Killifish, Fundulus Grandis, Sylvia Mullen
Senior Honors Theses
Metabolic rate is an essential feature of animal physiology and ecology. The rate of aerobic metabolism, as determined by oxygen consumption rate (MO2), is influenced by a variety of factors, including body size, temperature, and activity levels. Maximum aerobic metabolic rate (MMR) reflects the physiological capacity of an animal for oxygen extraction and utilization. As such, MMR is argued to be an important feature of an animal’s life history. For fish, MMR is frequently estimated as the peak MO2 immediately following an exhaustive chase, although several studies indicate that this value may underestimate MMR. Rather, MMR may be attained during …

Fluctuating Parasite Prevalence Is Not Linked To Patterns Of Mhc Class Ii-Ss Diversity In An Island Endemic Reptile, Gina Zwicky
Fluctuating Parasite Prevalence Is Not Linked To Patterns Of Mhc Class Ii-Ss Diversity In An Island Endemic Reptile, Gina Zwicky
University of New Orleans Theses and Dissertations
Few studies have explored the evolutionary mechanisms that maintain adaptive immunogenetic diversity in nature. We took advantage of museum samples to test for evidence of parasite-mediated fluctuating selection at MHC Class II-ß loci in an endemic island reptile. The Saban anole Anolis sabanus is commonly infected with three species of malaria (Plasmodium). Proportions of each parasite species detected in anole blood samples fluctuated over space and time, suggesting competitive interactions between parasites or differences in vector ecology. Our analyses of parasite prevalence and MHC Class II-ß allelic variation found that malaria infection was not associated with patterns of …
