Mechanisms Of Cigarette Smoke-Induced Mitochondrial Dysfunction In Striated Muscle And Aorta, Stephen T. Decker

Doctoral Dissertations

Cigarette Smoke is a significant cause of morbidity and mortality in the United States, accounting for over 480,000 annual deaths. Of these deaths, the most common cause of mortality in chronic smokers is cardiometabolic diseases. Likewise, a significant portion of smokers experience some form of cardiac, vascular, or metabolic dysfunction throughout their lifetime. More specifically, smoking is shown to induce mitochondrial dysfunction in these tissues, causing an increase in oxidative damage and poor overall health. However, despite the advances in the health outcomes related to cigarette smoke exposure, the mechanisms underlying mitochondrial dysfunction in striated muscle and the vasculature remain …

Pharmacy

Anxiety is one of the most prevalent forms of psychopathology that afects millions worldwide. It gained more importance under the pandemic status that resulted in higher anxiety prevalence. Anxiolytic drugs such as benzodiazepines have an unfavorable risk/beneft ratio resulting in a shift toward active ingredients with better safety profle such as the naturally occurring quercetin (QRC). The delivery of QRC is hampered by its low water solubility and low bioavailability. The potential to enhance QRC delivery to the brain utilizing polymeric nanocapsules administered intranasally is investigated in the current study. Polymeric nanocapsules were prepared utilizing the nanoprecipitation technique. The best …

Health Effects Of Neonicotinoids On An Agricultural Community, Jocelyn Rodriguez-Paar

Capstone Experience

Mead, Nebraska, a small United States agricultural community consisting of approximately 600 people, was accidentally exposed to high amounts of neonicotinoids when AltEn, an ethanol plant that used neonicotinoid coated corn and soybean seeds for biofuel, was discovered not disposing of the toxic byproduct safely. Coincidentally, there was also a leak in their wastewater system that also contaminated the nearby areas. Although neonicotinoids are not considered highly dangerous with low dose exposures, large dose exposures can cause symptoms similarly to nicotine poisonings, such as difficulty breathing, vomiting, nausea, hypertension, tachycardia, and lethargy (Imamura, T. et al., 2010). Neonicotinoid poisoning can …

Non-Thesis Student Work

To determine the effect of pharmacological and nonpharmacological treatments for seasonal depression in college students, we asked the following evidence-based PICO question: In college students (ages 18-25) with seasonal affective disorder (SAD), how does SSRI (Selective Serotonin Reuptake Inhibitor) therapy compared to light therapy affect seasonal depression syndrome? Seasonal affective disorder is synonymously used with the terminology seasonal depression due to the clinical manifestations that encompass depression, such as low energy, feelings of sadness, emptiness, or hopelessness. SAD begins in the fall months and peaks in the winter months due to a decrease in Vitamin D and ultraviolet (UV) ray …

Synthesis Of Alginate/Hydroxyapatite Beads For Acetaminophen Delivery, Anesylvia Angan, Nonni Soraya Sambudi

Makara Journal of Science

Conventional drug delivery systems usually involve the intake of multiple drugs, which could amplify the risk of overdosing. Acetaminophen is a widely used pain relief substance that is prone to accidental overdosing. Hence, a controlled drug delivery system is needed to ensure its efficacy. A nanocomposite hydroxyapatite/alginate system that was used as a drug carrier for acetaminophen was synthesized through the sol-gel method, and the mechanism underlying its controlled drug delivery was investigated. Spherical nanocomposite bead samples were synthesized by incorporating 5 wt%, 10 wt%, and 15 wt% hydroxyapatite into mixtures containing alginate. The mixtures were then dropped into calcium …

The Intersection Between Toxicology And Aging Research: A Toxic Aging Coin Perspective., John P. Wise Jr.

Faculty Scholarship

We are imminently faced with the challenges of an increasingly aging population and longer lifespans due to improved health care. Concomitantly, we are faced with ubiquitous environmental pollution linked with various health effects and age-related diseases which contribute to increased morbidity with age. Geriatric populations are rarely considered in the development of environmental regulations or in toxicology research. Today, life expectancy is often into one’s 80s or beyond, which means multiple decades living as a geriatric individual. Hence, adverse health effects and late-onset diseases might be due to environmental exposures as a geriatric, and we currently have no way of …

Roles Of Oxidative Stress And Dna Methylation In Cigarette Smoking-Induced Accelerated Acute Myeloid Leukemia Progression, Mary Figueroa

Dissertations & Theses (Open Access)

Acute myeloid leukemia (AML) is a commonly diagnosed cancer in smokers. When current or former smokers have AML, they have worse survival compared to never smoking patients. This has been observed clinically for decades, but then it is unknown how smoking leads to worsened AML survival. Smoking causes oxidative stress and altered DNA methylation that persists for decades in peripheral blood mononuclear cells, but these changes from smoking have not been evaluated in the context of AML. We hypothesize that smoking-induced molecular changes, including altered DNA methylation associated with poor AML prognosis, promote AML. We developed a novel model to …

Cortisol Receptor Sensitivity As A Risk Factor For Depression, Michela Michielli

Honors Theses

In 2020, the World Health Organization reported over 264 million people across the world were suffering from depression. Studies have demonstrated that one source of depression is a hormonal imbalance involved in the stress response. Cortisol is a stress hormone regulated by the Hypothalamic-Anterior-Pituitary (HPA) Axis. Its effects on the stress response and other metabolic activities in the body are exerted through the glucocorticoid and mineralocorticoid receptors (GR and MR respectively).

Our research has examined mutations known as single-nucleotide-polymorphisms (SNPs) relating to cortisol-receptor sensitivity and the behavior of cortisol in the body to investigate the link between cortisol activity and …

Achieving Better Care In Pennsylvania By Allowing Pharmacists To Practice Pharmacy, Travis Murray

Dickinson Law Review (2017-Present)

Traditionally, state legislatures implemented Prescription Drug Monitoring Programs (“PDMPs”) to assist prescribers, pharmacists, and law enforcement in identifying patients likely to misuse, abuse, or divert controlled substances. PDMP databases contain a catalog of a patient’s recent controlled substances that pharmacies have filled, including the date, location, the quantity of medication filled, and the prescribing health care provider. Prescribers in Pennsylvania have a duty to query the PDMP before prescribing controlled substances in most clinical settings. Pharmacists have a similar duty in Pennsylvania to dispense safe and effective medication therapy to patients and to screen patients for potential signs of misuse, …

The Effects Of Maternal Delta-9-Tetrahydrocannabinol And Cannabidiol Exposure On Fetal Heart Development In Mice, Gregory Robinson

Electronic Thesis and Dissertation Repository

Up to 22.6% of pregnant women consume cannabis during pregnancy despite the uncertainty of teratogenicity of the main ingredients in cannabis, delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). This study tested the hypothesis that gestational THC and CBD exposure leads to heart abnormalities. Daily, oral THC exposure induced heart abnormalities in 68% of offspring with three main phenotypes including thickened semilunar valves, ventricular myocardial hypertrophy and hypoplastic coronary arteries in fetuses, and postnatal cardiac dysfunction. Altered gene expression of key cardiogenic regulators, increased proliferation, and reduced epicardial epithelial-to-mesenchymal-transition were demonstrated implicating potential mechanisms responsible for these abnormalities. Also, maternal CBD exposure resulted …
