Characterization Of Sex Differences In The Reinforcing Effects Of Nicotine, Rodolfo Jesus Flores Garcia 2017 University of Texas at El Paso

Characterization Of Sex Differences In The Reinforcing Effects Of Nicotine, Rodolfo Jesus Flores Garcia

Open Access Theses & Dissertations

It is presently unclear whether ovarian hormones, such as estradiol (E2) promote the reinforcing effects of nicotine in females. Thus, we compared extended access to nicotine intravenous self-administration (IVSA) in intact male, intact female, and OVX female rats (Study 1) as well as OVX females that received vehicle or E2 supplementation (Study 2). The E2 supplementation procedure involved a 4-day procedure involving 2 days of vehicle administration and 2 days of E2 administration. Two doses of E2 (25 or 250 ug) were assessed in separate groups of OVX females in order to examine the dose-dependent effects of this hormone on …

Integration Of Biological Effects, Fish Histopathology And Contaminant Measurements For The Assessment Of Fish Health: A Pilot Application In Irish Marine Waters, Michelle Giltrap, Jenny Ronan, John Bignell, Brett Lyons, Evelyn Collins, Heather Rochford, Brendan Mchugh, Evin Mcgovern, Lorraine Bull, James Wilson

Articles

This study investigates the use of a weight of evidence (WOE) approach to evaluate fish health status and biological effects (BEs) of contaminants for assessment of ecosystem health and discusses its potential application in support of the Marine Strategy Framework Directive (MSFD). External fish disease, liver histopathology and several BEs of contaminant exposure including 7-ethoxy resorufin O-de-ethylase (EROD), acetylcholinesterase (AChE), bile metabolites, vitellogenin (VTG) and alkali labile phosphates (ALP) were measured in two flatfish species from four locations in Ireland. Contaminant levels in fish were generally low with PCBs in fish liver below OSPAR environmental assessment criteria (EAC). There were …


Mercury Bioaccumulation In Three Popular Subsistence And Recreational Estuarine Fishes From Southeastern U.S.A., Taylor Cannon 2017 University of South Carolina

Mercury Bioaccumulation In Three Popular Subsistence And Recreational Estuarine Fishes From Southeastern U.S.A., Taylor Cannon

Theses and Dissertations

A rising concern in recent years has occurred over the presence of methylmercury in seafood, particularly fishes, and its impact on human health. However, fish also provide many health benefits, including improved cardiovascular health and neurodevelopment. Because fishes are the main source of methylmercury exposure to humans, and are such an integral part of the human diet, understanding the risks versus the benefits of fish consumption is imperative in allowing the public to make healthy, educated choices. One way that state and federal governments attempt to do this is through issuing fish consumption advisories. Unfortunately, these advisories do not always …


A Study Of Hepatic Purinergic Receptor X7 Molecular Mechanisms In Ectopic Intestinal Inflammation In Environmental Nafld, Varun Chandrashekaran 2017 University of South Carolina

A Study Of Hepatic Purinergic Receptor X7 Molecular Mechanisms In Ectopic Intestinal Inflammation In Environmental Nafld, Varun Chandrashekaran

Theses and Dissertations

Due to the increased consumption of unhealthy foods rich in sugar and fat along with a highly sedentary lifestyle the prevalence of obesity has steadily increased in the United States and the rest of the world. In America about one third of the adult population is obese putting them at a greater risk for diseases such as cancer, cardio-vascular disorders, inflammation and metabolic diseases such as diabetes and non-alcoholic fatty liver disease (NAFLD). NAFLD can be classified into two major categories non-alcoholic fatty liver (NAFL) and non-alcoholic steato-hepatitis depending on the extent of damage which ranges from simple fat accumulation …


Chronic Effects Of Lead Exposure On Atherinops Affinis (Topsmelt): Influence Of Salinity And Organism Age, Erik Joseph Reynolds 2017 Loyola University Chicago

Chronic Effects Of Lead Exposure On Atherinops Affinis (Topsmelt): Influence Of Salinity And Organism Age, Erik Joseph Reynolds

Master's Theses

Pb (lead) appears in the environment as a consequence of both natural and anthropogenic processes. Mining, smelting, coal burning, lead acid batteries, and cement manufacturing substantially release Pb into aquatic environments. The goal of this study was to determine the influence of salinity and organism age on chronic toxicity of Pb to Atherinops affinis (topsmelt) in support of development of a species sensitivity distribution (SSD). Species sensitivity distributions assist in ecological risk assessments and establishing quality criteria for contaminants. Three chronic exposure studies were conducted for 28 days in a water flow-through testing system. Survival, standard length, dry weight, and …


Three Dimensional Homology Modeling Of Organic Cation Transporter 3 To Identify Structural Elements Mediating Transporter-Substrate Interactions, Hebing Liu 2017 Virginia Commonwealth University

Three Dimensional Homology Modeling Of Organic Cation Transporter 3 To Identify Structural Elements Mediating Transporter-Substrate Interactions, Hebing Liu

Theses and Dissertations

Organic cation transporters (OCTs) play a pivotal role in the absorption, tissue distribution, and excretion of a diverse array of substances, and currently the nature of the biochemical interactions between substrate and OCTs are unknown. Therefore, identifying which amino acid residues are critical for OCT-substrate interactions is of central importance to understanding and predicting interactions between drugs and OCTs. A three-dimensional (3-D) homology model of human OCT3 was generated using the crystal structure of a high affinity phosphate transporter from Piriformospora indica (PiPT) as template, and putative binding pocket for the prototypical hOCT3 ligand 1-methyl-4-phenylpyridinium (MPP+) was identified …


Alpha6 Beta2 Subunit Containing Nicotinic Acetylcholine Receptor Contributions To Abuse-Related Effects Of Nicotine And Alcohol, Alexandra M. Stafford 2017 Virginia Commonwealth University

Alpha6 Beta2 Subunit Containing Nicotinic Acetylcholine Receptor Contributions To Abuse-Related Effects Of Nicotine And Alcohol, Alexandra M. Stafford

Theses and Dissertations

Pharmacotherapies for tobacco and alcohol cessation are only modestly successful, so it is important to better understand mechanisms underlying their use and abuse. The overarching goal of this research is to assess a6b2 subunit containing nicotinic acetylcholine receptor (a6b2*nAChR; *denotes possible assembly with other subunits) contributions to abuse-related effects of nicotine and alcohol. In the absence of a6b2*nAChR-selective agonists, a6b2*nAChR gain-of-function (a6L9’S) mice provide a tool for selective activation of a6b2*nAChRs. Using the a6L9’S mice together with nicotine doses sub-threshold for stimulation of native nAChRs, these studies tested the hypothesis that activation of a6b2*nAChRs is sufficient to promote neurochemical and …


Ethanol Reversal Of Oxycodone Tolerances, Joanna C. Jacob 2017 Virginia Commonwealth University

Ethanol Reversal Of Oxycodone Tolerances, Joanna C. Jacob

Theses and Dissertations

Oxycodone is a semi-synthetic opioid originally developed as a safer alternative to morphine. It is commonly prescribed for its pain-relieving effects, but has recently been implicated as a major underlying cause of the current opioid epidemic due to its clinical limitations that include tolerance, dependence and a high abuse liability. Simultaneous consumption of opioids and ethanol has been shown to increase the risk of overdose and death from opioids in opioid-tolerant individuals. We hypothesized that ethanol reversed opioid tolerance and previous studies showed that ethanol reversed morphine tolerance. This dissertation investigated whether ethanol reversed tolerance to other opioids in mice, …
