Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell Jun 2022

Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell

Dissertations, Theses, and Capstone Projects

Successful regulation of fear memories is a fundamental tenet to the exposure-based therapies often employed by mental health professionals for individuals with PTSD, phobias, and other anxiety disorders. Consequently, the efficacy of these treatment methodologies is largely dependent on the strength of the fear memory, as stronger memories are often characterized by an increased resistance to extinction and heightened fear recovery. However, there is little consensus within the scientific community regarding how to effectively maximize fear memory strength in human studies, and the literature exploring the impact of variability in acquisition parameters on memory strength is sparse. Here, we tested ...


Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal Jun 2022

Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal

Dissertations, Theses, and Capstone Projects

The impact of deforestation on the genetic structure of mouse lemurs is poorly understood. In this project, I assess deforestation of Madagascar’s terrestrial protected regions, quantify genomic wide genetic variation in two sympatric mouse lemurs, and evaluate the role of landscape structure in genetic relatedness patterns within two sympatric mouse lemur species. Overall deforestation rates across the 98 terrestrial protected areas in Madagascar are increasing, resulting in an average annual deforestation rate of 0.68% per year, with approximately 10,600 km2 lost between 2000 and 2019. In a comparison of relatedness patterns between the sympatric gray mouse ...


The Impact Of Focused Attention And Opening Monitoring Meditation Styles On Attention, Jennifer Wheary Jun 2022

The Impact Of Focused Attention And Opening Monitoring Meditation Styles On Attention, Jennifer Wheary

Dissertations, Theses, and Capstone Projects

Mindfulness meditation – often broken down into two distinct types, focused attention (FA) and open monitoring (OM) – has been associated with a range of affective and attentional benefits. Using an attentional blink (AB) paradigm that demonstrated improved attention for novice FA meditators, we explored whether novices who engaged in a single, brief bout of meditation exhibited any differences in alpha or theta power during meditation, and whether these differences were apparent by meditation type. In the AB paradigm, participants are asked to identify two targets, T1 and T2, which are separated by 200-500 ms. Our results showed no significant differences between ...


Cdc6 Is Sequentially Regulated By Pp2a-Cdc55, Cdc14, And Sic1 For Origin Licensing In S. Cerevisiae, Jasmin Philip Jun 2022

Cdc6 Is Sequentially Regulated By Pp2a-Cdc55, Cdc14, And Sic1 For Origin Licensing In S. Cerevisiae, Jasmin Philip

Dissertations, Theses, and Capstone Projects

Control of DNA replication is critical for progression of the cell cycle and genomic stability. Cyclin-dependent kinases (CDKs) coordinate numerous phosphorylation events to accomplish two biological tasks for all living organisms: DNA replication and cell division. One CDK, Cyclin-Cdc28, is responsible for cell cycle progression in budding yeast. DNA replication requires a stepwise assembly of the pre-replicative complex on DNA, including Orc1-6, Cdc6, Cdt1 and Mcm2-7, during M-G1 phase. Cdc6 contains eight Cdc28 consensus sites, SP or TP motifs. Clb5-Cdc28 phosphorylates Cdc6-T7 to recruit Cks1, the Cdc28 phospho-adaptor, for subsequent multisite phosphorylation during S phase. There are two phospho-degrons at ...


Elucidating Mechanisms Of Biofluorescence And Bioluminescence In Marine Organisms, Andrew M. Guarnaccia Jun 2022

Elucidating Mechanisms Of Biofluorescence And Bioluminescence In Marine Organisms, Andrew M. Guarnaccia

Dissertations, Theses, and Capstone Projects

Biofluorescence and bioluminescence are two methods of light emission that entail separate mechanisms of action but end at the same process: a colorful display that have tremendous ecological and behavioral benefits, whether it be used to communicate with conspecifics, camouflage into a multicolored background, attract unsuspecting prey, or alert others to a predator. In biofluorescence, higher-energy, shorter wavelength light is absorbed then re-emitted as lower-energy, longer-wavelength light. Bioluminescence on the other hand entails a chemical reaction in which a small molecule is oxidized by an enzyme, creating a high-energy intermediate that sheds the excess energy in the form of visible ...


Robert Rosen And Relational System Theory: An Overview, James Lennox Jun 2022

Robert Rosen And Relational System Theory: An Overview, James Lennox

Dissertations, Theses, and Capstone Projects

Relational system theory is the science of organization and function. It is the study of how systems are organized which is based on their functions and the relations between their functions. The science was originally developed by Nicolas Rashevsky, and further developed by Rashevsky’s student Robert Rosen, and continues to be developed by Rosen’s student A. H. Louie amongst others. Due to its revolutionary character, it is often misunderstood, and to some, controversial. We will mainly be focusing on Rosen’s contributions to this science. The formal and conceptual setting for Rosen’s relational system theory is category ...


Investigating Steady State Visually Evoked Potentials As A Novel Biosignature For Anxiety-Related Attention Bias, Elizabeth R. Davis Jun 2022

Investigating Steady State Visually Evoked Potentials As A Novel Biosignature For Anxiety-Related Attention Bias, Elizabeth R. Davis

Dissertations, Theses, and Capstone Projects

Anxiety-related attention bias (AB), a type of cognitive bias underlying the development and maintenance of anxiety disorders, is typically defined as exaggerated attention towards threat; however, some individuals also demonstrate AB away from threat and in some instances, no detectable AB at all. Debate about the reliability and validity of AB behavioral measures has prompted examination of additional assessment methods. Neurophysiological methods, such electroencephalography (EEG), have yielded encouraging early findings. The steady-state visually evoked potential (SSVEP), a measure of selective visual attention derived from EEG, holds promise as a biosignature for AB. Research documents heightened SSVEP power to emotionally salient ...


Molecular Mechanism Of Rapamycin Resistance In Cancer Cells, Sohag Chakraborty Jun 2022

Molecular Mechanism Of Rapamycin Resistance In Cancer Cells, Sohag Chakraborty

Dissertations, Theses, and Capstone Projects

The mammalian target of rapamycin (mTOR) acts as the central regulator of multiple cellular processes including cell growth, proliferation, and survival by integrating signals via nutrients, growth factors, hormones, and energy sensing. In cancer cells, the mTOR pathway is highly dysregulated providing survival signals to the cells for their uncontrolled growth. Hence, mTOR has evolved to be a potential therapeutic target for cancer treatment for the past two decades. Application of micro-molar doses of Rapamycin in vitro has been found to successfully inhibit mTOR complex 1 (mTORC1) by blocking the phosphorylation of its downstream substrates- a) ribosomal protein p70 S6 ...

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh Feb 2022

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh

Publications and Research

Background

Heterochrony, change in the rate or timing of development, is thought to be one of the main drivers of morphological evolution, and allometry, trait scaling patterns imposed by size, is traditionally thought to represent an evolutionary constraint. However, recent studies suggest that the ontogenetic allometric trajectories describing how organisms change as they grow may be labile and adaptive. Here we investigated the role of postnatal ontogenetic development in the morphological diversification of Paleoanguimorpha, the monitor lizards and allies, a clade with extreme body size disparity. We obtained linear and geometric morphometric data for more than 1,600 specimens belonging ...


Novel Strategies For Glutamate Clearance In The Glia-Deprived Synaptic Hub Of C. Elegans, Joyce Chan Feb 2022

Novel Strategies For Glutamate Clearance In The Glia-Deprived Synaptic Hub Of C. Elegans, Joyce Chan

Dissertations, Theses, and Capstone Projects

As the major excitatory neurotransmitter in the mammalian brain, Glutamate (Glu) is critical for normal neuronal physiology. Disruption in Glu clearance results in hyper-stimulation of glutamatergic circuits, potentially leading to excitotoxic neurodegeneration. The canonical model of brain connectivity describes glutamatergic synapses as well insulated and enveloped by glia. These glia express Glu Transporters (GluTs) which work to clear Glu following synaptic activity. However, critical areas of the brain such as the mammalian hippocampus display poor synaptic isolation, which may result in Glu spillover between adjacent synapses and subsequent loss of circuit specificity. How accurate signal transmission is achieved in these ...


Conservation, Comparative Genomics And Species Delimitation Of The Reindeer Lichens (Cladonia), Jordan R. Hoffman Feb 2022

Conservation, Comparative Genomics And Species Delimitation Of The Reindeer Lichens (Cladonia), Jordan R. Hoffman

Dissertations, Theses, and Capstone Projects

The genus Cladonia represents one of the most speciose genera of lichenized fungi, with more than 500 known species encompassing a diverse array of morphologies and habits. These lichens form keystone species in many habitats, serving a variety of ecological roles. However, despite being among of the more well studied lichens, there is much still unknown or under-studied about them. As is the case with most lichen study systems, phylogenetic study has been limited to a small number of partial loci, while adoption of next-generation sequence methods has been slow. As a consequence, there are still knowledge gaps in Cladonia ...


An In Silico Approach To Investigate The Structural And Biochemical Basis Of The Rna Binding Functions Of Nucleolin, Avdar San Feb 2022

An In Silico Approach To Investigate The Structural And Biochemical Basis Of The Rna Binding Functions Of Nucleolin, Avdar San

Dissertations, Theses, and Capstone Projects

Nucleolin (NCL) is a stress responsive multifunctional nucleolar protein and accounts for 10% of the total nucleolar protein content. NCL belongs to the class of RNA binding proteins (RBPs) that regulate many important cellular processes through their interactions with different RNA molecules. The dysregulation of RBPs and the RNA metabolism pathways they intersect is a known driver of tumorigenesis. NCL regulates ribosome biogenesis, chromatin remodeling, microRNA processing, and gene expression on multiple levels. The RNA-protein interactions of NCL are primarily driven by its four RNA binding domains (RBDs). NCL is known to interact with a growing list of primary-miRNA (pri-miRNA ...


Eukaryotic Initiation Factor 3 Interactions With Structural Elements Of Barley Yellow Dwarf Virus Untranslated Regions Reveal Details Of A New Cap-Independent Translation Initiation Model, Paul S. Powell Feb 2022

Eukaryotic Initiation Factor 3 Interactions With Structural Elements Of Barley Yellow Dwarf Virus Untranslated Regions Reveal Details Of A New Cap-Independent Translation Initiation Model, Paul S. Powell

Dissertations, Theses, and Capstone Projects

Barley Yellow Dwarf Virus (BYDV) is a positive strand RNA plant virus that translates without using a 5′ 7-methylguanosine cap or a 3′ poly-adenosine tail, features that are required for canonical mRNA translation. BYDV’s non-canonical translation relies on RNA structures in the 5′ and 3′ untranslated regions (UTRs) to recruit eukaryotic initiation factors (eIFs) and ribosomes. BYDV’s 3′ translation enhancer (BTE) is a cruciform structure capable of recruiting the cap-binding complex eIF4F, the large scaffolding complex eIF3, and the 40S ribosomal subunit. Together eIF3, eIF4F, and BTE influence factor binding and 40S recruitment on the 5′ UTR and ...


Histone Post-Translational Modification Dysregulation Contributes To Toxicity In Amyotrophic Lateral Sclerosis Proteinopathy Models, Seth A. Bennett Feb 2022

Histone Post-Translational Modification Dysregulation Contributes To Toxicity In Amyotrophic Lateral Sclerosis Proteinopathy Models, Seth A. Bennett

Dissertations, Theses, and Capstone Projects

Amyotrophic Lateral Sclerosis (ALS) is the third most common adult onset neurodegenerative disorder worldwide. It is generally characterized by progressive paralysis starting at the limbs ultimately leading to death caused by respiratory failure. There is no cure and current treatments fail to slow the progression of the disease. As such, new treatment options are desperately needed. Epigenetic targets are an attractive possibility because they are reversible. Epigenetics refers to heritable changes in gene expression unrelated to changes in DNA sequence. Histone modifications, a main epigenetic mechanism, occur in many amino acid residues and include phosphorylation, acetylation, methylation as well as ...


Reducing Fear Overgeneralization With Safety Learning: Attention Bias As A Moderator, Boyang Fan Feb 2022

Reducing Fear Overgeneralization With Safety Learning: Attention Bias As A Moderator, Boyang Fan

Dissertations, Theses, and Capstone Projects

Anxiety disorders are the most prevalent mental health condition and affect one out of nine individuals around the world. Fear generalization is a neurocognitive mechanism thought to maintain and exacerbate anxiety, and thus is an important target of therapeutic interventions. Yet, intervention research and practice place relatively little emphasis on its importance. Given that a significant proportion of individuals do not respond to extant treatments of anxiety disorders, a strengthened focus on fear generalization may inform the development and personalization of new treatment approaches. Recent notions have linked fear generalization to failures in distinguishing between signals that predict the occurrence ...


Molecular Mechanisms Of Microrna-1205 In Aggressive Prostate Cancer, Michelle K. Naidoo Feb 2022

Molecular Mechanisms Of Microrna-1205 In Aggressive Prostate Cancer, Michelle K. Naidoo

Dissertations, Theses, and Capstone Projects

Prostate cancer (PCa) is one of the most commonly diagnosed cancers among men in the United States. High mortality rates of PCa are associated with metastatic castration-resistant prostate cancer (mCRPC) due to the maintenance of androgen receptor (AR) signaling despite androgen deprivation therapies (ADTs). Resistance to second generation ADTs leads to the progression of AR-independent treatment related-neuroendocrine PCa (t-NEPC), which is observed in nearly 1 in 5 men with mCRPC and is associated with very poor outcomes. The 8q24 chromosomal locus is a region of very high PCa susceptibility that carries genetic variants associated with PCa aggressiveness. Located at this ...


Scientific Development Of An Integrated Workflow For Latent Print, Questioned Document, And Dna Processing Of Paper Evidence, Ashley Morgan Feb 2022

Scientific Development Of An Integrated Workflow For Latent Print, Questioned Document, And Dna Processing Of Paper Evidence, Ashley Morgan

Dissertations, Theses, and Capstone Projects

Touch paper evidence could be the source of probative human DNA but recovery is challenging and forensic laboratories instead prioritize processing by the Latent Print and Questioned Document disciplines. Recent advances in DNA collection methods and the increased sensitivity of STR typing kits have improved success rates for DNA testing of paper evidence; but prior to implementing DNA collection, laboratories have to decide in which order to examine paper for the different types of forensic evidence. This thesis developed and tested a multi-discipline workflow for processing paper evidence by DNA, Latent Prints and Questioned Documents experts. Preliminary sampling studies indicated ...

HIV pre-exposure prophylaxis (PrEP) is dominated by clinical therapeutic antiretroviral (ARV) drugs. Griffithsin (GRFT) is a non-ARV lectin with potent anti-HIV activity. GRFT’s preclinical safety, lack of systemic absorption after vaginal administration in animal studies, and lack of cross-resistance with existing ARV drugs prompted its development for topical HIV PrEP. We investigated safety, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of PC-6500 (0.1% GRFT in a carrageenan (CG) gel) in healthy women after vaginal administration. This randomized, placebo-controlled, parallel group, double-blind first-in-human phase 1 study enrolled healthy, HIV-negative, non-pregnant women aged 24–45 years. In the open label period ...

Reproducibility Of Individual Dna Deposits Detected Through Cellular Fluorescence, Natalee Small-Davidson

Student Theses

Contact traces are an important part of DNA casework, but the probative value of any identified associations depends on the possibility of passive transfer. There is known individual variation in DNA left behind during contact, this DNA shedding propensity has an effect on whose DNA is detected. This study evaluated this variability using a cell staining approach. Volunteers were asked to deposit a fingerprint on a clean glass slide, then wash their hands and deposit a second fingerprint after a 30-minute wait without touching anything. Three sets of samples were collected over three consecutive weeks. Fingerprints were stained with a ...
