Do Environmental Toxins Predict Violent Crimes?, 2021 Kennesaw State University
Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl
Symposium of Student Scholars
Do chemical pollutants that persistent in the environment and bioaccumulate in the body affect human health and behavior? Could these Persistent, Bioaccumulative, and Toxic (PBT) chemicals play a role in the cause of violent crimes due to deterioration of mental and cognitive functions? In the past, Mercury, a PBT chemical, has been shown in salmon to be associated with aggression. Could similar aggression occur in humans exposed to mercury through a toxic spill? Two sources of data are utilized in this analysis. The Environmental Protection Agency’s (EPA) Annual Toxic Release Inventory publishes data on toxic releases into the environment ...
Addressing Uncertainties Of Polychlorinated Biphenyls In Schools, 2021 The University of San Francisco
Addressing Uncertainties Of Polychlorinated Biphenyls In Schools, Alice Fan
Master's Projects and Capstones
Despite the potential neurological health deficits resulting from polychlorinated biphenyls, there is a lack of inhalation studies and regulations to protect students and teachers who are widely exposed to PCBs in older (1950 to 1979) schools. To estimate the extent of PCB detections in Los Angeles County schools, I applied a mathematical model to estimate the range of PCB detections in schools built between 1950 and 1984. I estimate the range of 17-34% PCB detections of open schools within Los Angeles County. Next, I reviewed exposure tools provided by the US EPA to bridge the uncertainty gaps between ingestion and ...

Characterizing Pm2.5 Air Samples Of Northeast Mississippi, Harley Nabors
Ambient air pollution has been associated with adverse health effects throughout the entire world. Although epidemiologists study air pollution extensively, rural areas are often the least understood. In 2020, the Mississippi Department of Environmental Quality used less than 10 air sampling locations across the state leaving a large gap in air quality knowledge. In this study, fine particulate matter (PM2.5) air samples were collected from three different rural Mississippi cities–Ackerman, Eupora, and Houston, in the summer of 2020. Following collection onto filters, elemental black carbon analysis and an oxidative potential assay were both used to characterize the samples ...
Surface-Eroding Drug Delivery Films For Sequential And/Or Intermittent Release Of Psychoactive Drugs, 2021 University of Mississippi
Surface-Eroding Drug Delivery Films For Sequential And/Or Intermittent Release Of Psychoactive Drugs, Jason Price
ABSTRACT JASON BLAKE PRICE: Surface-Eroding Drug Delivery Films for Sequential and/or
Intermittent Release of Psychoactive Drugs For patients with psychiatric diseases, adherence to medication schedules, medication
errors, and abuse are common issues. Promising new forms of therapy for these patients, such as micro-dosed lysergic acid diethylamide (LSD), where patients receive 10-20% of a full dose every third day, present further drug delivery challenges. Sequential or intermittent release of drugs from an implanted device could ensure long-term drug compliance, automate drug dosing during the life of the implant, and eliminate potential for abuse and medication errors. To this end, we ...

Department of Biology Faculty Scholarship and Creative Works
Biofilm, a stress-induced physiological state, is an established means of antimicrobial tolerance. A perpetual increase in multidrug resistant (MDR) infections associated with high mortality and morbidity have been observed in healthcare settings. Multiple studies have indicated that the use of natural products can prevent bacterial growth. Recent studies in the field have identified that epigallocatechin gallate (EGCG), a green tea polyphenol, could disrupt bacterial biofilms. A modified lipid-soluble EGCG, epigallocatechin-3-gallate-stearate (EGCG-S), has enhanced the beneficial properties of green tea. This study focuses on utilizing EGCG-S as a novel synergistic agent with antibiotics to prevent or control biofilm. Different formulations of ...

The Open Neuroscience Initiative is a free-to-use textbook
This project began as a means to overcoming the financial burden that face undergraduate neuroscience students when buying textbooks. By compiling and writing a completely free-to-access textbook that covers the foundations of a typical college introduction to neuroscience course, students would have one less obstacle to overcome in their educational career, allowing them to focus their valuable time and attention on learning rather than finances. To make this project a reality, I began with a humble tweet in May 2019 that managed to gain a tiny bit of traction among the neuroscience ...
Achieving Better Care In Pennsylvania By Allowing Pharmacists To Practice Pharmacy, 2021 Penn State Dickinson Law
Achieving Better Care In Pennsylvania By Allowing Pharmacists To Practice Pharmacy, Travis Murray
Dickinson Law Review
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 ...
Opioid Use Disorder: The Timeline For Medication Assisted Therapy, 2021 Arcadia University
Opioid Use Disorder: The Timeline For Medication Assisted Therapy, Alexander Cristofori
Opioid Use Disorder is patterns of opioid use leading to withdrawal, giving up important life events in order to use opioids, and excessive time spent using opioids, to name a few diagnostic criteria. The clinical progression of the disorder involves periods of acute exacerbation and remission that are cyclic in nature. Treatment is most effective when it includes both pharmacological and psychosocial modalities, referred to as medication assisted therapy (MAT). Three drugs used commonly in MAT-based treatment for OUD from oldest to newest include Methadone, Buprenorphine-naloxone, and Naltrexone. Treatment program models that prioritize total abstinence from the addictive substance attached ...

Chemically Induced Phytoextraction Of Lead (Pb) Contaminated Soil By Switchgrass (Panicum Virgatum L.), Austin Gilly
Master of Science in Integrative Biology Theses
Soils contaminated with lead (Pb) from human activities including industrial byproducts create an environmental and human health risk. Phytoextraction through chemical acquisition of Pb in soils offer a potentially cost effective and ecologically driven approach to remediation. Switchgrass (Panicum virgatum L.) is known to have a tolerance for a wide range of heavy metals including Pb. Switchgrass is also able to grow in a wide range of climates. Soil chemistry manipulation, using chelates and plant growth promoters could provide an effective field method for phytoremediation using switchgrass. In this study chemically enhanced phytoextraction using the soil-fungicide Infuse (active ingredient propiconazole ...

The aim of this work was to evaluate the transformation of manganese oxide (hausmannite) by microscopic filamentous fungus Aspergillus niger and the effects of the transformation on mobility and bioavailability of arsenic. Our results showed that the A. niger strain CBS 140837 greatly affected the stability of hausmannite and induced its transformation into biogenic crystals of manganese oxalates—falottaite and lindbergite. The transformation was enabled by fungal acidolysis of hausmannite and subsequent release of manganese ions into the culture medium. While almost 45% of manganese was bioextracted, the arsenic content in manganese precipitates increased throughout the 25-day static cultivation of ...

Nano-fertilisers have only recently been introduced to intensify plant production, and there still remains inadequate scientific knowledge on their plant-related effects. This paper therefore compares the effects of two nano-fertilisers on common sunflower production under field conditions. The benefits arising from the foliar application of micronutrient-based zinc oxide fertiliser were compared with those from the titanium dioxide plant-growth enhancer. Both the zinc oxide (ZnO) and titanium dioxide (TiO2) were delivered by foliar application in nano-size at a concentration of 2.6 mg·L−1. The foliar-applied nanoparticles (NPs) had good crystallinity and a mean size distribution under 30 nm ...
Understanding Neonicotinoid Related Immunosuppression: A Potential For Beneficial Bacterial Intervention, 2020 The University of Western Ontario
Understanding Neonicotinoid Related Immunosuppression: A Potential For Beneficial Bacterial Intervention, John A. Chmiel
Electronic Thesis and Dissertation Repository
The use of neonicotinoid pesticides has been implicated in the recent decrease of honey bee (Apis mellifera) populations. In this thesis, a Drosophila melanogaster model was used to characterize immune impairment associated with imidacloprid (neonicotinoid) exposure and test the ability of beneficial bacteria (lactobacilli) to alleviate these harmful effects. The experiments outlined in chapters 2 and 3 demonstrate that imidacloprid alters the gut microbiota by exploiting the cooperation between gut immune pathways. The pesticide reduces expression of Duox via dysregulation of the immune deficiency pathway resulting in decreased hydrogen peroxide production. This contributes to the microbiota changes but also depletes ...
