Substance use disorders (SUD) account for a large number of mental health diagnosis in the United States and around the world. Approximately 13.6 million adults 26 or older and 5.1 million young adults (ages 18-24) battled with a SUD in 2017. Alcohol Use Disorder (AUD) alone effects nearly 6% of the adult population within the United States. This creates a substantial burden on the individual, with alcohol being the third-leading cause of preventable death in the United States. Few treatments for AUD exist, with no new FDA-approved therapeutic treatments within the last 15 years. Additionally, the limited treatments we do …
Interclass Gpcr Heteromerization Affects Localization And Trafficking, Rudy Toneatti
Interclass Gpcr Heteromerization Affects Localization And Trafficking, Rudy Toneatti
Theses and Dissertations
Class A serotonin (5-hydroxytryptamine) 2A (5-HT2AR) and class C metabotropic glutamate 2 receptors (mGluR2) are seven transmembrane receptors (7TMRs or G protein-coupled receptors – GPCRs) involved in multiple neuropsychiatric disorders including schizophrenia. Previous findings from our laboratory reported that 5-HT2AR and mGluR2 are dysregulated in the prefrontal cortex of patients suffering from this psychiatric condition, although 5-HT2AR’s expression was recovered in antipsychotic-medicated patients. Genome-wide association studies on schizophrenia reported that endosomal trafficking that regulates cell surface abundance of another 7TMR implicated in this disease (dopamine D2 receptor) can be altered. Ligand-activated receptors, including the …
Pharmacophoric Evaluation Of 5-Ht2a And 5-Ht2b Serotonin Recpeptors, Prithvi Hemanth
Pharmacophoric Evaluation Of 5-Ht2a And 5-Ht2b Serotonin Recpeptors, Prithvi Hemanth
Theses and Dissertations
Serotonin (5-HT) receptors represent a class of receptors involved in a variety of physiological processes including regulation of mood, perception, cognition, appetite, and heart function, and thus serve as drug targets of several drugs such as antipsychotic agents, hallucinogenic drugs, and appetite suppressant drugs. Due to the structural similarity of certain 5-HT receptor subtypes, particularly 5-HT2 receptors (5-HT2A, 5-HT2B receptors) determination and refinement of pharmacophore models of these receptor subtypes can greatly improve the therapeutic efficacy of drugs that target them.
The goals of this study were to define and/or refine existing pharmacophore models for 5-HT …
Dendrimer-Based Antibiotics For The Treatment Of Bacterial Biofilm In Cystic Fibrosis (Cf), Younan Ma
Dendrimer-Based Antibiotics For The Treatment Of Bacterial Biofilm In Cystic Fibrosis (Cf), Younan Ma
Theses and Dissertations
Pseudomonas aeruginosa (PA) is the predominant pathogen in chronic lung infections of cystic fibrosis (CF) patients. The most important mechanism of adaptation of PA to host defense and antibiotic treatment is the formation of biofilms within the mucus layer covering the lung bronchi. The effectiveness of antibiotics such as aminoglycosides is significantly attenuated by their limited penetration through thick mucus and embedded biofilm matrix in patients’ lung. Inhaled tobramycin (Tobra), which is the most commonly used antibiotics in the treatment of PA infections for CF patients, is usually found to be in very high concentration in patients’ lung, and yet …
The Cb1 Receptor Positive Allosteric Modulator, Zcz011, Attenuates Naloxone-Precipitated Withdrawal Signs In Oxycodone-Dependent Mice And Inhibits Small Intestinal Transit In Mice, Julien Dodu
Theses and Dissertations
The endogenous cannabinoid system tightly regulates a myriad of physiological and pathophysiological functions. Effects of cannabinoids in ameliorating opioid withdrawal signs has been known for decades. Naloxone precipitates several withdrawal signs (e.g., diarrhea, weight loss, jumps, paw flutters, and head shakes) in opioid dependent rodents. ∆9-tetrahydrocannabinol (THC) has been shown to ameliorate opioid withdrawal in mice through the activation of cannabinoid type-1 (CB1) receptors. Inhibition of the endocannabinoid degradative enzymes also attenuates these withdrawal signs (i.e., diarrhea, weight loss, jumps, paw flutters, and head shakes) in opioid-dependent mice. Specifically, inhibition of fatty acid amide hydrolase (FAAH), …
Investigating Cannabinoid Type-1 Receptor (Cb1r) Positive Allosteric Modulators (Pams) In Mouse Models Of Overt Cannabimimetic Activity, Subjective Drug Effects, And Neuropathic Pain, Jayden Elmer
Theses and Dissertations
Chronic pain affects between 20 and 30 percent of the adult population in western countries and represents a wide array of specific etiologies (Berge, 2011). Neuropathic pain secondary to traumatic nerve injury, chemotherapeutic toxicity, or diseases (e.g., diabetes mellitus) is often refractory to conventional analgesics, with patients receiving less than 50% pain relief compared to placebo (Finnerup et al. 2010). The endocannabinoid system has shown potential as a therapeutic target for neuropathic pain wherein CB1 agonism via administration of exogenous agonists or pharmacological blockade of endocannabinoid catabolic enzymes exhibits efficacy in reversing allodynia in the chronic constriction injury (CCI) model …
Nebulizer-Based Systems To Improve Pharmaceutical Aerosol Delivery To The Lungs, Benjamin M. Spence
Nebulizer-Based Systems To Improve Pharmaceutical Aerosol Delivery To The Lungs, Benjamin M. Spence
Theses and Dissertations
Combining vibrating mesh nebulizers with additional new technologies leads to substantial improvements in pharmaceutical aerosol delivery to the lungs across therapeutic administration methods. In this dissertation, streamlined components, aerosol administration synchronization, and/or Excipient Enhanced Growth (EEG) technologies were utilized to develop and test several novel devices and aerosol delivery systems. The first focus of this work was to improve the poor delivery efficiency, e.g., 3.6% of nominal dose (Dugernier et al. 2017), of aerosolized medication administration to adult human subjects concurrent with high flow nasal cannula (HFNC) therapy, a form of continuous-flow non-invasive ventilation (NIV). The developed Low-Volume Mixer-Heater (LVMH) …
