Effects Of Electronic Cigarette Liquid Solvents Propylene Glycol And Vegetable Glycerin On User Nicotine Delivery, Heart Rate, Subjective Effects, And Puff Topography, Tory Spindle 2018 Virginia Commonwealth University

Effects Of Electronic Cigarette Liquid Solvents Propylene Glycol And Vegetable Glycerin On User Nicotine Delivery, Heart Rate, Subjective Effects, And Puff Topography, Tory Spindle

Theses and Dissertations

Electronic cigarettes (ECIGs) are a class of tobacco products that use a heating element to aerosolize a liquid, typically containing nicotine, allowing for user inhalation. Despite their rapid growth in popularity, little is known about ECIGs including how certain device and liquid factors influence nicotine delivery, user physiological and subjective responses, and puffing behavior (puff topography). Limited pre-clinical research has demonstrated that the ratio of two solvents commonly found in ECIG liquids, propylene glycol (PG) and vegetable glycerin (VG), may have an influence on the nicotine content of ECIG aerosols. However, the extent to which PG:VG ratio in ECIG liquids …

Regulatory Issues Concerning The Preclinical Testing Of Synthetic Peptides, Vamsi Vardhan Niraghatam

Master's Theses and Doctoral Dissertations

Any new drug or biological product undergoes rigorous testing in animals and humans for review by the United States Food and Drug Administration (FDA) before it becomes available for human use. A sponsor files an investigational new drug (IND) application with the FDA with supporting animal data, after which testing is continued with humans. There is sufficient guidance from the FDA on new small molecules and biological products as to which preclinical studies are to be conducted. Synthetic peptides present a unique scenario in which a case-by-case approach is needed for the conduct of preclinical studies. For peptides containing components …

Arsenic In Groundwater In South West Ireland - Occurrence, Controls, And Hydrochemistry, Ellen R. Mcgrory, Emma Holian, Alberto Alvarez-Iglesias, Norma Bargary, Eoin Mcgillicuddy, Henry Tiernan, Liam Morrison

Articles

Globally numerous regions have been identified with elevated arsenic within groundwater which can result in potential adverse health risks. In Ireland, a previous national-scale research assessment of groundwater identified isolated clusters of elevated arsenic and indicated that lithology was a major controlling factor on arsenic in groundwater. Complementary comparisons of national-scale and regional-scale groundwater assessments of arsenic are lacking in Europe when compared to other global regions. The aims of this study were to demonstrate the value of a regional-scale groundwater hydrochemistry dataset with an existing national-scale approach, describe anomalies that can become the focus of attention for public health …

Lorcaserin As A Potential Opioid-Sparing Adjunct, Kumiko M. Lippold 2018 Virginia Commonwealth University

Lorcaserin As A Potential Opioid-Sparing Adjunct, Kumiko M. Lippold

Theses and Dissertations

Opioids, such as oxycodone, morphine, and fentanyl, are commonly used medications in the treatment of moderate to severe pain. In spite of their efficacious analgesic properties, their increased prescribing rates by physicians and inherent abuse-related effects have led to the ongoing opioid epidemic. Their clinical utility is limited by the risk of adverse dose-dependent side effects, such as constipation and respiratory depression, and the development of tolerance and dependence. Opioid-sparing adjunctive therapies are sought to address these issues by reducing the dose of opioid needed to achieve analgesia through alternative non-opioidergic mechanisms and as a result, reduce the incidence of …


Molecular Brain Adaptations To Ethanol: Role Of Glycogen Synthase Kinase-3 Beta In The Transition To Excessive Consumption, Andrew D. van der Vaart 2018 Virginia Commonwealth University

Molecular Brain Adaptations To Ethanol: Role Of Glycogen Synthase Kinase-3 Beta In The Transition To Excessive Consumption, Andrew D. Van Der Vaart

Theses and Dissertations

Alcoholism is a complex neuropsychiatric disease that is characterized by compulsive alcohol use and intensifying cravings and withdrawals, often culminating in physiologic dependency. Fundamental alterations in brain chemistry underlie the transition from initial ethanol exposure to repetitive excessive use. Key mediators of this adaptation include changes in gene expression and signal transduction. Here we investigated gene expression pathways in prefrontal cortex and nucleus accumbens following acute or chronic ethanol treatment, to identify genes with potentially conserved involvement in the long-term response of the corticolimbic system to repeated ethanol exposure. We investigated Gsk3b, which encodes glycogen synthase kinase 3-beta, as a …

Browse all Theses and Dissertations

The primary function of Na⁺/K⁺ATPase (NKA) discovered by Jens Christian Skou in 1958, through electrogenic exchange of 3 Na⁺ for 2 K⁺ ions (Robert L Post, 1958), is the homeostatic preservation of their electrochemical gradient across the plasma membrane (PM) of almost all species and their derived cell lines. Cardiotonic steroids (CTS), such as cardenolides or bufadienolides, are well established inhibitors of NKA. Fox glove plant extracts containing CTS, including digitalis, were first described by William Withering (1744-91) for their positive inotropic effect in heart failure patients. Later research identified the mechanism of their action through direct inhibition of NKA …


Polychlorinated Biphenyls, Thyroid Hormones, And Neuropsychological Function Among Older Adults From Upstate New York, Eva M. Tanner 2018 University at Albany, State University of New York

Polychlorinated Biphenyls, Thyroid Hormones, And Neuropsychological Function Among Older Adults From Upstate New York, Eva M. Tanner

Legacy Theses & Dissertations (2009 - 2024)

Polychlorinated biphenyls (PCBs) are a class of persistent organic pollutants linked to changes in cognitive function and thyroid hormone (TH) levels. However, most studies of PCBs and cognitive function were conducted among children. No studies among older adults have prospectively collected PCB and cognitive performance measurements to evaluate the association over time, and no longitudinal studies have evaluated the association between PCBs and THs over time among a non-occupationally exposed population. Further, the biological mechanism by which PCBs impact cognitive function is unknown, but may be mediated by THs. In addition, reliable self-reported survey data is necessary to obtain precise …
