Stress During Adolescence: A Characterization Of Anxiety-Like Behavior, And The Mrna Expression Of Neuroimmune Factors, Clock And Stress Genes In Corticolimbic Areas., Annette Fernandez Oropeza, Annette K. Fernandez Oropeza Dec 2025

Stress During Adolescence: A Characterization Of Anxiety-Like Behavior, And The Mrna Expression Of Neuroimmune Factors, Clock And Stress Genes In Corticolimbic Areas., Annette Fernandez Oropeza, Annette K. Fernandez Oropeza

Biomedical Sciences ETDs

Adolescence represents a critical window of frontal cortex (FC) maturation and corticolimbic circuit refinement that supports stress and emotion regulation. Disruption of these processes by early-life insults such as prenatal alcohol exposure (PAE) or adolescent stress increases vulnerability to anxiety and mood disorders, in part through circadian–immune dysregulation. The circadian transcription factor Bmal1 and the proinflammatory cytokine tumor necrosis factor-alpha (TNFα) have emerged as key regulators of neuroimmune signaling and synaptic communication, yet their interactions across developmental risk contexts remain poorly understood. This dissertation examined the effects of mild adolescent isolation stress, with and without PAE, on anxiety-like behaviors and …


The Pathophysiological Role Of Mitochondrial Acid-Sensing Ion Channel 1a In Hypoxic Pulmonary Hypertension, Megan N. Tuineau Dec 2025

The Pathophysiological Role Of Mitochondrial Acid-Sensing Ion Channel 1a In Hypoxic Pulmonary Hypertension, Megan N. Tuineau

Biomedical Sciences ETDs

Pulmonary hypertension (PH) is characterized by increased pulmonary arterial constriction, pulmonary arterial remodeling, and right ventricular dysfunction. While metabolic and mitochondrial derangements are increasingly recognized as central pathogenic features, the underlying mechanisms and effectors are not yet fully understood. Acid-sensing ion channel 1a (ASIC1a) is a proton-gated cation channel involved in the development of chronic hypoxia (CH)-induced PH. ASIC1a represents a potential candidate involved in metabolic-mitochondrial dysfunction, as metabolic byproducts can act as ligands for ASIC1a. Additionally, ASIC1a has recently been identified as a mitochondrial ion channel involved in neuronal death following oxidative stress. Therefore, we hypothesize that ASIC1a functions …

KRASG12D mutation is a prevalent gain-of-function mutation that drives pancreatic cancer tumorigenesis, but the underlying mechanisms that promote KRAS-induced cell proliferation and tumor formation remain elusive. To uncover the molecular pathways that facilitate KRASG12D-driven malignant transformation, we measured the transcriptomic alterations at various time points after induction of KRASG12D expression in human pancreatic normal epithelial cells. KEGG pathway enrichment of the differentially expressed genes (DEGs) showed that the major DEGs were located in pathways that regulate nicotinate/nicotinamide metabolism, TNF signaling, and microRNAs associated with cancer. Among these molecular alterations, the NAD-dependent deacetylase gene SIRT3 was significantly down-regulated by KRASG12D. Conversely, …

Background: Seizures are one of the most common reasons for emergency medical services (EMS) activation for children, and current EMS practice results in underdosing and delayed delivery of anti-seizure medication. A prehospital evidence-based guideline recommends using intranasal or intramuscular midazolam as first-line treatment for pediatric seizures. Despite attempts to implement these guidelines, one-third of children having a paramedic-witnessed seizure have ongoing seizures on emergency department (ED) arrival; this may be due to inadequate or delayed midazolam dosing. Replacing the error-prone, sequential calculations with age-based midazolam dosing may be simpler, faster, and more effective without compromising safety. The objective of this …

Florida Journal of Emergency Medicine (FJEM)

A 55-year-old woman with rheumatoid arthritis and supraventricular tachycardia presented with acute chest pain radiating to the back/left shoulder, with nausea and lightheadedness. Initial ECG showed inferior–lateral ST-segment elevation with reciprocal depressions; within 90 minutes the STE resolved with new incomplete RBBB and diffuse low voltage. High-sensitivity troponin rose (delta ~270 ng/L). Point-of-care and formal echocardiography revealed LV wall-motion abnormalities. Emergent catheterization showed no obstructive CAD (<30% distal OM) with apical ballooning and EF 40–45%, consistent with Takotsubo cardiomyopathy; cardiac MRI confirmed myocardial edema. She was managed with anticoagulation initially, telemetry, and supportive care, and recovered uneventfully with normalization of function on follow-up.

Complete Atrioventricular Block In A Heart Transplant Recipient, Jalyn Joseph, Morgan Reel, Eric Boccio Dec 2025

Complete Atrioventricular Block In A Heart Transplant Recipient, Jalyn Joseph, Morgan Reel, Eric Boccio

Florida Journal of Emergency Medicine (FJEM)

Complete atrioventricular (AV) block, though uncommon in heart transplant recipients, is a potentially life-threatening condition that demands rapid diagnosis and management in the acute care setting. During complete AV block, there is a failure of electrical conduction from the atria to the ventricles resulting in the independent and dyssynchronous contraction of the heart chambers. Due to the resultant decrease in cardiac output, patients may experience lightheadedness, fatigue, shortness of breath, syncope and near syncope, and, in severe cases, cardiogenic shock may develop. A 58-year-old female with past medical history including hypertension, diabetes, chronic kidney disease, and congestive heart failure and …
