Molecular Mechanisms Underlying Environmental Enrichment-Induced Neuroprotection In Vulnerability To Nicotine Addiction, Adrian Michael Gomez

Theses and Dissertations

Tobacco use is the number one preventable cause of death in the world. Nicotine is the principal, addictive component in tobacco responsible for its reinforcing properties that drive the behavioral manifestations of nicotine addiction. Environment is becoming increasingly implicated in nicotine susceptibility. However, the molecular mechanisms that underlie susceptibility to nicotine addiction remain unknown. An ideal animal model that addresses environmental factors uses rats raised in an enriched condition (EC), a standard condition (SC), and an impoverished condition (IC); which differ in novelty, social cohorts, handling, and physical activity. EC rats exhibit a neuroprotective-like phenotype in the behavioral resistance to …

Vitamin C: A Potential Regulator Of Inflammatory Response, Bassem M. Mohammed

Theses and Dissertations

Introduction: Neutrophils (PMNs) and Macrophages are the first responders recruited consecutively to the site of injury/inflammation. PMNs’ response/fate as well as macrophage reprogramming ultimately determine the course of resolution of inflammation. Physiologic wound healing has a significant inflammatory component. An exaggerated inflammation however is self-defeating leading to delayed healing. Parenteral vitamin C (VitC) attenuated inflammation in murine sepsis models and in patients with sepsis. However information about the mechanisms by which VitC regulates these events is limited.

Methods: Humanized mice lacking VitC synthesis capability (Gulo^-/-) were used. VitC sufficient and deficient mice were challenged with sterile inflammation, or …

Use Of Low-Dose Ketamine For Pain Management In An Emergency Department, Joseph Ladd, Winifred Pardo

All Publications

Background/Purpose: In the emergency department (ED), many barriers exist to pain management. Non-steroidal anti-inflammatory drugs and acetaminophen often cannot provide enough relief, while opioid analgesics are hindered by side effects, dependency, and tolerance. A non-competitive NMDA receptor antagonist, ketamine has historically been used for sedation and anesthesia in rural settings or in those with limited resources. Ketamine's unique safety profile and variety of dosage forms indicate its potential role in pain management. An evaluation was conducted of ketamine's use in low doses to treat pain in an emergency department with the third-greatest annual census in Miami-Dade county.

Methodology: A retroactive …

Semi-structured interviews with residents who used the ED, an existing database …

Psychoactive Synthetic Cathinones (Or 'Bath Salts'): Investigation Of Mechanisms Of Action, Farhana Sakloth

Theses and Dissertations

Synthetic cathinones represent threatening and high abuse-potential designer drugs. These are analogs of cathinone (the b-keto analog of amphetamine (AMPH)) a naturally occurring stimulant found in the plant Catha Edulis. Methcathinone (MCAT) was the first synthetic analog of cathinone to be identified in 1987 by Glennon and co-workers and it exerted its action primarily through the dopamine transporter (DAT). Most central stimulants exert their action via monomaine transporters by causing either the release (e.g. cathinone analogs such as MCAT) or by preventing the reuptake (e.g. cocaine) of the neurotransmitter dopamine (DA) thus increasing the extracellular synaptosomal concentration of this …

Feasibility Of Integrating Tripterygium Wilfordii Into Modern Cancer Therapy For Increased Efficacy And Minimal Toxicity, Ngoc T. Vo

UROP Posters

Cancer is the second leading cause of death in the U.S. and millions of novel cancer cases are being diagnosed each year. While chemotherapy and ionizing radiation are effective treatments against these malignant tumors, the adverse effects that accompany such treatments are devastating. In order to find alternative treatment methods with less side effects, we turn to Eastern herbal medicine. Recent scientific research has found that Tripterygium wilfordii, an herbal medicine traditionally used to treat inflammation in China, contains compounds (triptolide and celastrol) that prevent the growth of solid tumors, induce apoptosis, and prevent metastasis of developed tumors. Investigations …

Evaluation Of Purkinje Neurons And Endocannabinoid Receptors As A Potential Target Of Alcoholism Using Japanese Medaka (Oryzias Latipes) As An Animal Model, J. Ford Franklin

Honors Theses

Purkinje cells (PK) are neurons with large cell bodies found in the central nervous system and are mostly distributed in the cerebellar region of the hindbrain. Several novel markers for PK cells have been developed and are used for characterization of neurobehavioral disorders. The present study was aimed to identify endocannabinoid receptor 1 (CB1) as a potential marker of PK cells and evaluate them as a molecular target of alcohol and cerebellar functions using Japanese medaka (Oryzias latipes) as an animal model. Previously, we have observed that medaka genome consist three CB receptor paralogs; two of them (cnr1a and cnr1b) …

Reference Material Development For Paralytic Shellfish Poisoning Toxins And Associated Analytical Applications, Stephen Burrell

Doctoral

Food poisoning incidences relating to marine biotoxins are a global phenomenon and have the potential to severely impact the aquaculture industry. As a result, and as a legislative requirement in the European Union (EU), many countries have implemented monitoring programmes for these compounds but their success relies on the availability of certain quality assurance tools, two of which are reference materials (RMs) and proficiency testing. The limited amounts of RMs, in particular matrix certified reference materials (CRMs) for paralytic shellfish poisoning (PSP) toxins has been a limiting factor in the implementation of alternatives to the mouse bioassay for routine monitoring …

Predicting Aqueous Solubility Of Pharmaceutical Agents By Solid Dispersion Prepared By Solvent Evaporation Method, Karthik Reddy Patlolla

University of the Pacific Theses and Dissertations

Solubility of active pharmaceutical agents is a crucial process that determines drug absorption and ultimately its bioavailability. Many of the new therapeutically beneficial compounds discovered are lipophilic requiring various solubility enhancement strategies to improve their solubility. Among these strategies, solubility enhancement using solid dispersions is a leading method. To obtain a desirable increase in the solubility of a poorly-soluble compound, a good understanding of the molecular descriptors influencing the enhancement of solubility is essential. Therefore, the major research objective was to determine the descriptors which significantly influence the solubility enhancement by solid dispersions. After enhancing the solubility of selected poorly-soluble …

Investigation Of Phenylephrine Sulfation And Inhibition Using A Novel Hilic Assay Method, Heta N. Shah

Theses and Dissertations

Phenylephrine (PE) is the most commonly used over-the-counter nasal decongestant. The problem associated with phenylephrine is that it undergoes extensive first pass metabolism in the intestinal gut wall leading to its poor and variable oral bioavailability.

This research project aims at developing strategies in order to increase the oral bioavailability of PE by co-administration of GRAS compounds. A HILIC assay method was developed to detect the parent drug, phenylephrine (PE) and its sulfate metabolite (PES).The enzyme kinetic studies were done with phenolic dietary or GRAS compounds using LS180 human intestinal cell model, recombinant SULT enzymes and human intestinal cytosol (HIC). …

Enhancement Of The Placental Transmission Of Lopinavir Using A Transporter Targeted Prodrug Strategy, Meng Wang

Theses and Dissertations

Lopinavir (LPV) is a potent protease inhibitor specific for HIV-1. However, LPV has poor placental penetration due to substrate activity for efflux transporter by P-glycoprotein (P-gp). Since fatty acid transporters are highly expressed in the placenta during pregnancy, we designed fatty acid ester prodrug of lopinavir as substrates of fatty acid transporter in order to improve their uptake into placenta. Seven dicarboxylic acid esters of lopinavir have been made in our lab. The structures were characterized by ¹H-NMR, ¹³C-NMR, LC-MS/MS, HRMS, IR and melting points. After making the prodrugs, an LC-MS/MS method with high specificity and sensitivity, as …

The administration of enantiopure drugs brings advantages such as improved efficacy, more predictable pharmacokinetics and reduced toxicity from the point of view of the pharmaceutical area.[1] For this reason, a tremendous amount of supply and demand for enantiomeric pure compounds has been shown not only in market, but industry and academia.[^2-4] According to the industry publication Genetic Engineering and Biotechnology News (GEN) in 2014, 22 billion dollars were accounted for enantiopure form of drugs such as Sovaldi® (Sofosbuvir), Crestor® (Rosuvastatin), and Advair® (fluticasone/salmeterol).

The fact that one enantiomer can be pharmacologically effective whereas the other enantiomer can be …

Binding Of Dna By A Dinitro-Diester Calix[4]Arene: Denaturation And Condensation Of Dna, Mary Deasy, Pilar Lopez-Cornejo, F J. Ostos, J A. Lebron, M L. Moya

Articles

A study of a dinitro-diester calix[4]arene (5,17-(3-nitrobenzylideneamino)-11,23-di-tert-butyl- 25,27-diethoxycarbonyl methyleneoxy-26,28-dihydroxycalix[4]arene) interaction with calf-thymus DNA was carried out using several techniques. The measurements were done at various molar ratios X=[calixarene]/[DNA]. Results show diverse changes in the DNA conformation depending on the X value. Thus, at low macrocycle concentration, the calixarene binds to the polynucleotide. This interaction, mainly in groove mode, weakens the hydrogen bonds between the base pairs of the helix inducing the denaturation of the double strands, as well as the condensation of the macromolecule, from an extended coil state to a globular state. An opposite effect is observed …

The Hispanic Pharmacist: Value Beyond A Common Language, Gabriela C. Cipriano, Carlota O. Andrews

Pharmacy Faculty/Staff Publications

Objective: To highlight the added value of bilingual Hispanic pharmacists in the care of Hispanic patients by sharing their patients’ language and culture.

Summary: Inability to speak and/or write in the patients’ native language severely impairs our best efforts to deliver good health care. This is a widely recognized cause of non-compliance or less than favorable possible health outcomes in Hispanic patients. What has received less attention, however, is that the ability to speak Spanish alone may not remove completely the barrier for non-compliance among Hispanics. Bilingual Spanish–English pharmacists do not have the language barrier, but if they do not …
