Comparative Analyses Of Adeno-Associated Viral Vector Serotypes 1, 2 And 9 In The Sod Mouse Model Of Amyotrophic Lateral Sclerosis, Talia Hartman, Jeremy Francis, Paola Leone

Rowan-Virtua Research Day

6–7-week-old G93A SOD mice were given 1x1010 vector genomes of three different self-complimentary (sc) AAV capsid serotypes (AAV1, 2, and 9) all containing an identical CBh-driven GFP reporter expression cassette. Each serotype was delivered via either the intrathecal (IT) or intra cisterna magna (ICM) route of administration (ROA). Transduction by each serotype, via each of the two ROA was compared for the cortex and each of the lumbar, thoracic, and cervical regions of the spinal cord, with percent neuronal tropism calculated in each region. AAV2 was effective at transducing spinal cord neurons but disappointingly ineffective at transducing cortical neurons by …

Intra-Accumbens Microinfusion Of The Dopamine D3 Receptor Partial Agonist (±)Vk4-40 Does Not Affect Basal Locomotion In Mice, Yeonwoo Sim, Nicole M. Hinds, Amy Hauck Newman, Daniel F. Manvich

Rowan-Virtua Research Day

The opioid epidemic remains a pressing public health crisis, prompting the search for alternative pharmacotherapies for Opioid Use Disorder (OUD). This study explores the potential of the dopamine D3 receptor (D3R) partial agonist, (±)VK4-40, as a novel treatment option. We investigated the impact of intra-nucleus accumbens (NAc) microinfusion of VK4-40 on basal locomotion in mice. Results indicate that VK4-40 did not significantly alter basal locomotion, suggesting that its therapeutic effects may not be mediated through disruptions in generalized motor function. Future research will focus on elucidating the neuropharmacological mechanisms underlying VK4-40's therapeutic actions and exploring its effects on psychostimulant-induced hyperlocomotion. …

Towards Understanding The Function Of An Ets-Like Gene In Nematostella Vectensis: Generation Of A Knockout Mutant Line And A Transgenic Reporter Line, Emily Bullock

Biological Sciences Undergraduate Honors Theses

Due to their unique phylogenic position as sister to Bilateria, Cnidaria are often credited with the utility of allowing for reconstruction of ancestral biology based on characteristics shared with bilaterians and other animals. This factor makes investigation into the nervous systems of cnidarians critical in understanding early neural evolution. Wamides, a class of neuropeptides, have been shown to play a regulatory role in life cycle transitions across many different species. The cnidarian specific Wamide neuropeptide, GLWamide, has previously been identified to play an accelerator role in the metamorphic timing of a specific species of sea anemone, Nematostella vectensis. However, …

Biophysical Model Of Retraction Motor Neurons And Their Modification By Operant Conditioning, Maria Rasheed

Dissertations & Theses (Open Access)

Operant conditioning (OC) is a form of associative learning in which an animal modifies its behavior based on the consequences that follow that behavior. Despite its ubiquity, the underlying mechanisms of OC are poorly understood. Insights into the mechanisms of OC can be obtained by studying Aplysia feeding behavior as it can be modified by OC. This behavior is mediated by a central pattern generator (CPG) network in the buccal ganglia that contains a relatively small number of neurons. This CPG generates rhythmic motor patterns (BMPs) that move food into the gut by closing a tongue-like structure (i.e., radula) during …

The Anatomical Embodiment Of Morning Routines In The Reduction Of Anxiety: An Intervention, Natalie Wright

Expressive Therapies Capstone Theses

The topic under investigation is whether physically embodying a morning routine that was designed through the lens of Laban Bartenieff Movement Analysis (LBMA) will reduce daily symptoms of individuals diagnosed with Generalized Anxiety Disorder.

Since morning routines play a significant part in one’s preparation for the day, I created an individualized LBMA morning routine for a specific client to embody. In addition to the routine, the client documented the process of their anxiety levels on a weekly basis. This client was a white, female, 19-year-old, lesbian college student who was previously diagnosed with Generalized Anxiety Disorder (GAD). The movement analysis …

Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto

Dissertations, Theses, and Capstone Projects

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson

Honors College Theses

The purpose of this research is to improve understanding of the neurodevelopmental effects of embryonic exposure to elevated inflammation and oxidative stress induced by the antipyretic drug acetaminophen (APAP). Our study was the first to examine the interactive effects of APAP and inflammation in zebrafish embryos and how the treatments affect brain development and larval behavior. Experimental groups of zebrafish larvae were exposed to lipopolysaccharide (LPS) to induce inflammation, APAP, or LPS + APAP and larval behavior was analyzed using Ethovision automated behavioral tracking software. We also measured changes in whole-brain Glycogen Synthase Kinase 3 Beta (GSK3B) and GSK3B phosphorylation, …
