Investigating The Developmental Impacts Of 3,3’-Dichlorobiphenyl (Pcb-11) In Zebrafish (Danio Rerio), Monika A. Roy
Investigating The Developmental Impacts Of 3,3’-Dichlorobiphenyl (Pcb-11) In Zebrafish (Danio Rerio), Monika A. Roy
Doctoral Dissertations
The environmental pollutant 3,3’-dichlorobiphenyl (PCB-11) is a lower-chlorinated polychlorinated biphenyl (PCB) congener present in air and water samples. Both PCB-11 and its metabolite, 4-PCB-11-Sulfate, are detected in humans, including in pregnant women. The work conducted for this dissertation takes a developmental toxicology approach and uses zebrafish (Danio rerio) to investigate PCB-11’s potential impacts to the liver and pancreas. Chapter 1 introduces PCBs and the current knowledge gaps. Chapter 2 investigates PCB-11 interactions in short-term 4-day exposures with the Aryl hydrocarbon receptor (Ahr) pathway in both 0-20 mM individual and mixture exposures with other Ahr agonists. In Chapter 3, …
Evaluation Of Α-Pyrrolidindovalerophenone (Α-Pvp) And Its Isomers In Male And Female Sprague-Dawley Rats Trained To Discriminate Mdpv, Kaley Cargile
Evaluation Of Α-Pyrrolidindovalerophenone (Α-Pvp) And Its Isomers In Male And Female Sprague-Dawley Rats Trained To Discriminate Mdpv, Kaley Cargile
Masters Theses
Recreational use of synthetic cathinones, 3,4-methylenedioxypyrovalerone (MDPV) and α‐pyrrolidinovalerophenone (α‐PVP), has become increasingly popular, thus prompting characterization of their behavioral and neurochemical effects. MDPV has been studied for several years now, though there is still much unknown about α‐PVP, and its isomers. The primary objective of this study was to characterize the discriminative effects of α‐PVP and its isomers in comparison to MDPV. Male and female Sprague-Dawley rats were trained to discriminate 0.5mg/kg MDPV from saline injections under a fixed ratio 20 (FR 20) schedule of food reinforcement. Substitution tests were conducted with MDPV (0.05-0.5mg/kg), α‐PVP (0.05-0.5mg/kg), (S)-α‐PVP (0.05-1mg/kg) and …
3,5-Dichloroaniline: Biotransformation And Mechanistic Aspects Of Nephrotoxicity In Vitro, Christopher Robert Racine
3,5-Dichloroaniline: Biotransformation And Mechanistic Aspects Of Nephrotoxicity In Vitro, Christopher Robert Racine
Theses, Dissertations and Capstones
Chlorinated anilines have been used as important chemical intermediates in the production of a wide variety of pharmaceutical, industrial, and agricultural products. Exposure to chloroanilines can arise in both occupational and environmental settings and can lead to toxicity to multiple organs, including the kidney. Previous studies have established that of the mono- and dichlorinated anilines, 3,5-dichloroaniline (3,5-DCA) possesses the most nephrotoxic potential both in vitro and in vivo. However, little is known concerning the role of renal metabolism in nephrotoxicity. The studies presented in the following dissertation are the first to explore the toxicity, metabolism, and bioactivation of 3,5-DCA in …
Immunoregulation Of Liver Regeneration By The Aryl Hydrocarbon Receptor: Role Of Lymphocytes And Interferon-Gamma, Christopher John Horras
Immunoregulation Of Liver Regeneration By The Aryl Hydrocarbon Receptor: Role Of Lymphocytes And Interferon-Gamma, Christopher John Horras
Boise State University Theses and Dissertations
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a persistent environmental contaminant that elicits toxicity by activating the aryl hydrocarbon receptor. The toxic effects associated with TCDD exposure include immunotoxicity and dysregulated cell cycle control, although the mechanisms are poorly understood. A previous report indicates that exposure to TCDD suppresses hepatocyte proliferation in a mouse model of liver regeneration induced by 70% partial hepatectomy (PH). Based on reports that liver regeneration is negatively regulated by interferon (IFN)-γ produced by activated natural killer (NK) cells, along with the well-established immunotoxic effects of TCDD in other model systems, we hypothesized that TCDD treatment attenuates liver …
