Sex Differences In The Mechanisms That Modulate The Neurochemical Effects Of Nicotine, Kevin Uribe

Open Access Theses & Dissertations

Prior behavioral studies in our laboratory revealed that overexpression of the stress peptide, corticotrophin-releasing factor (CRF), in the mesocorticolimbic reward pathway enhanced the reinforcing effects of nicotine. The latter effect was greater in female versus male rats, suggesting that females are uniquely susceptible to the effects of stress on nicotine reinforcement. The goal of this dissertation was to examine the neurochemical mechanisms by which overexpression of CRF in the nucleus accumbens (NAc), a terminal region of the mesocorticolimbic pathway, modulates the behavioral effects of nicotine. Specifically, we examined whether nicotine-induced dopamine levels are altered by CRF overexpression via excitatory (glutamate) …

The Effect Of Waterpipe/Hookah On Platelet Function And The Impact Of Inhibition Of Gβγ Subunits On Hemostasis And Thrombogenesis, Ahmed Alarabi

Open Access Theses & Dissertations

Abstract (Hookah)

Cardiovascular diseases (CVD’s) is a major public health problem. Among CVD’s risk factors, tobacco smoking is considered the single most preventable cause of death, with thrombosis being the main mechanism of CVD’s mortality in smokers. While tobacco smoking has been on the decline, the use of waterpipe/hookah has been rising, mainly due to the perception that they are “less harmful” than regular cigarettes. Strikingly, there are few studies on the negative effects of waterpipes on the cardiovascular system, and none regarding their direct contribution to thrombus formation. We employed a waterpipe whole-body exposure protocol that mimics real‐life human …

In-Vitro Localisation And Degradation Of Few-Layer Mos2 Submicrometric Plates In Human Macrophage-Like Cells: A Label Free Raman Micro-Spectroscopic Study, Caroline Moore, Andrew Hrvey, Jonathan N. Coleman, Hugh Byrne, Jennifer Mcintyre

Articles

Monitoring the uptake, micro-environment and fate of micro or nano scaled particulate materials in cells is of paramount importance for the emerging fields of toxicology and medicine. Such particulate materials are known to interfere with colorimetric assays and many such assays record only a single end-point. Therefore, there is a need for a label-free, cost effective technique with little or no inference from the particulate materials. Raman micro-spectroscopy was used to simultaneously interrogate the integrity of few-layer MoS2 submicrometric plates in human macrophage-like cells, in-vitro, as well as the biochemical characteristics of the local micro-environment in which they are encompassed. …

Reducing Reperfusion Injury In An Adult Rat Stroke Model With St-115 Treatment, Morgan Rae Lenz

Master's Theses

The restoration of blood flow to ischemic cerebral tissue can result in reperfusion injury, and blocking reperfusion injury can significantly aid in recovery of ischemic tissue. Bradykinin has been shown to exhibit protective effects, but does not reach protective levels during reperfusion due to inactivation by aminopeptidase P2 (APP2). Therefore, inhibiting APP2 during reperfusion is a potential therapeutic strategy to aid in the reduction of reperfusion injury, leading to the development of ST-115, an APP2 inhibitor. It was hypothesized that administration of ST-115 during ischemic stroke, and just prior to reperfusion, will result in reduced neurological injury and increased functional …

Distribution And Evolution Of Fukushima Dai-Ichi Derived 137cs, 90sr, And 129i In Surface Seawater Off The Coast Of Japan, Jennifer A. Kenyon, Ken O. Buesseler, Núria Casacuberta, Maxi Castrillejo, Shigeyoshi Otosaka, Pere Masqué, Jessica A. Drysdale, Steven M. Pike, Virginie Sanial

Research outputs 2014 to 2021

© 2020 American Chemical Society. The Fukushima Dai-ichi Nuclear Power Plants (FDNPPs) accident in 2011 led to an unprecedented release of radionuclides into the environment. Particularly important are 90Sr and 137Cs due to their known health detriments and long half-lives (T1/2 ≈ 30 y) relative to ecological systems. These radionuclides can be combined with the longer-lived 129I (T1/2 = 15.7 My) to trace hydrologic, atmospheric, oceanic, and geochemical processes. This study seeks to evaluate 137Cs, 90Sr, and 129I concentrations in seawater off the coast of Japan, reconcile the sources of contaminated waters, and assess the application of 137Cs/90Sr, 129I/137Cs, and …

Phytochemical Screening, In Vitro Antimalarial Activity And Genetic Diversity Of Selected Asteraceae Medicinal Plants Indigenous To Thailand, Desy Liana

Chulalongkorn University Theses and Dissertations (Chula ETD)

The emergence of artemisinin resistance leaded the effort to find the new antimalarial drug or artemisinin activity booster. Due to the chance that secondary metabolites can be evolutionary conserved, combining phylogeny with ethnobotanical data for screening antimalarial activity may be helpful to predict bioactivity and minimize the expenditure and time for laboratory research. The aimed of this study is screening the antimalarial activity, phytochemicals and genetic diversity of selected Asteraceae medicinal plants generated by combinatorial phylogeny and ethnobotanical data. 733 medicinal plants were obtained from literature search however only 340 taxa were met the inclusion and exclusion criteria hence these …

Pharmacology Of Fentanyl-Related Substances In Mice Reveals Potential Therapeutics With Improved Protective Indices, Neil B. Varshneya

Theses and Dissertations

Fentanyl-related substances constitute a class of compounds that were originally developed in the latter half of the 20th century as combination analgesic-anesthetic agents. Today, many of these compounds have emerged in the recreational drug marketplace as adulterants to heroin, counterfeit prescription pills, and even as standalone products designed to circumvent drug control laws. The objective of this dissertation was to identify the structural determinants of fentanyl analogs that could affect the potency and efficacy for eliciting their therapeutic and toxic effects to identify candidates of potential therapeutic interest. To accomplish this objective, thirty-eight fentanyl-related substances, in addition to the MOR …

Epigenetic Regulation Of Drug Metabolizing Enzymes In Normal Aging, Mohamad M. Kronfol

Theses and Dissertations

Geriatric populations are at a higher risk for adverse drug reactions (ADRs). This may be partly due to changes in drug metabolism in old age, but the underlying mechanisms are poorly understood. Prior research in humans and mice has shown age-associated changes to the expression of several genes involved in drug metabolism. Furthermore, studies of human blood showed that epigenetic regulation of genes encoding drug metabolizing enzymes change with age. However, it is unknown if genes in the liver are similarly affected. Therefore, we hypothesize that genes encoding drug metabolizing enzymes may show differential epigenetic regulation in the liver with …

Model-Based In-Vitro Pk/Pd Profiling Of Novel Synthetic Allosteric Effectors Of Hemoglobin (Aeh) As Potential Sickle Cell Disease (Scd) Therapeutics, Xiaomeng Xu

Theses and Dissertations

Introduction: Allosteric effectors of hemoglobin (AEH) represent a class of synthetic aromatic aldehydes that transiently form covalent interactions (Schiff-base) with hemoglobin (Hb) to form Hb-AEH adduct, preventing the HbS polymerization and sickling of red blood cells (RBC). The overall objective of this research was to aid in the optimization of novel AEH by understanding their target-site disposition of AEH in relevant biological matrices, e.g., HbA solution, whole blood (WB) and human liver cytosol (HLC), a surrogate of aldehyde dehydrogenase (ALDH)-mediated oxidative metabolism.

Methods: A “universal” HPLC-UV/Vis assay method was developed for the quantitation of HbA-AEH adduct for chemically …
