Characterizing Pm2.5 Air Samples Of Northeast Mississippi, 2021 University of Mississippi
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 ...

The association between humans and cats (Felis catus) is well known. This domestic animal is also known for its malodorous urine and feces. The complexity of the odorous urine and feces impacts human life by triggering the human sensory organ in a negative way. The objective of this research was to identify the volatile organic chemicals (VOCs) and associated odors in cat urine and feces using gas chromatography–mass spectrometry and simultaneous sensory analysis of fresh and aged samples. The solid-phase microextraction (SPME) technique was used to preconcentrate the VOCs emitted from urine or feces samples. Twenty-one compounds were identified ...
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 ...

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 ...

Q2S Enhancing Pedagogy
The project is the adoption of principles of Artificial Intelligence (AI)/Machine Learning and Data Analytics into a traditional nursing research (hypothesis testing) course. Necessitated by the recent entrance of “Big Data” use in health care, there is an urgent need to inject an understanding of the AI/ML techniques necessary to extract, organize and derive meaning from this huge amount of evidence in clinical decision-making. In fact, our department recently approved the adoption of Precision Health (PH) (the clinical use of the plethora of highly-individualized data in health & medical decisions) principles into six undergraduate courses, NURS 4222 (Nursing Research ...
The Effect Of Seasonality On Yellow Perch Ecology And Ecotoxicology Within Lake Manganese, 2020 Michigan Technological University
The Effect Of Seasonality On Yellow Perch Ecology And Ecotoxicology Within Lake Manganese, Bailey Duxbury
Dissertations, Master's Theses and Master's Reports
Seasonality is a consistent component of aquatic ecosystems yet most fish biological and ecotoxicological studies commonly employ field sampling protocols focused during the warm open water season with minimal emphasis placed on winter sampling, especially for north-temperate latitude ecosystems. Such strategies limit our understanding of poikilotherm biology and ecology during the overwintering seasons. Here, I investigated seasonal changes in yellow perch (Perca flavescens) biology, ecology and ecotoxicology over a one-year period in Lake Manganese. Significant seasonality was observed for metrics including fish energy densities (kJ/g), gonadosomatic indices, whole-body lipid contents, and carbon stable isotope values (δ13C). Mercury ...

The Exploration Of Nanotoxicological Copper And Interspecific Saccharomyces Hybrids, Matthew Joseph Winans Phd
Graduate Theses, Dissertations, and Problem Reports
Nanotechnology takes advantage of cellular biology’s natural nanoscale operations by interacting with biomolecules differently than soluble or bulk materials, often altering normal cellular processes such as metabolism or growth. To gain a better understanding of how copper nanoparticles hybridized on cellulose fibers called carboxymethyl cellulose (CMC) affected growth of Saccharomyces cerevisiae, the mechanisms of toxicity were explored. Multiple methodologies covering genetics, proteomics, metallomics, and metabolomics were used during this investigation. The work that lead to this dissertation discovered that these cellulosic copper nanoparticles had a unique toxicity compared to copper. Further investigation suggested a possible ionic or molecular mimicry ...
Antifungal Defense Molecules From Bacterial Symbionts Of North American Trachymyrmex Ants, 2020 Claremont Colleges
Antifungal Defense Molecules From Bacterial Symbionts Of North American Trachymyrmex Ants, Georgia Scherer
CMC Senior Theses
Defensive symbioses, in which microbes provide molecular defenses for an animal host, hold great potential as untapped sources of therapeutically useful antibiotics. Fungus-growing ants use antifungal defenses from bacterial symbionts to suppress pathogenic fungi in their nests. Preliminary chemical investigations of symbiotic bacteria from this large family of ants have uncovered novel antifungal molecules with therapeutic potential, such as dentigerumycin and selvamicin.
In this study, the bacterial symbionts of North American Trachymyrmex fungus-growing ants are investigated for antifungal molecules. Plate-based bioassays using ecologically-relevant fungal pathogens confirmed that these bacteria have antifungal activity. In order to purify and identify the antifungal ...

The Effect Of Prebiotics On Intestinal Digestion Of Carbohydrates In Lead Intoxicated Rats, Lubov S. Kuchkarova, Irodakhon I. Karimova, Gulchekhra T. Kudeshova, Khasan Yu. Kayumov
Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences
It has been shown the lead intoxication of growing rats result in increase the cavity and membrane carbohydrate hydrolysis and glucose absorption from small intestine which leads to hyperglicemiya. The oral treatment of intoxicated rats with inulin or lactulose results in decrease of carbohydrate assimilation in small intestine and content glucose level in blood. The correcting effect of lactulose on normalization of carbohydrate assimilation is more expressed in compare with inulin. So, inulin and/or lactulose take part in improving of adaptation of the carbohydrate assimilation system in the small intestine during intoxication with lead ions in growing rats. This ...

#39 - Extended-Spectrum Beta (Β) Lactamase-Producing Enterobacteriaceae Isolates From Flat Creek Water Samples, Luis Vidals, Maria Mayorga-Gutierrez
Georgia Undergraduate Research Conference (GURC)
Antibiotics have played a major role in containing bacterial infections. Extended spectrum beta (β) lactamases, better known as ESBLs, are enzymes produced by the bacterial family Enterobacteriaceae that inhibit the activity of many common antibiotics used today such as penicillin. The genes that encode for ESBLs are bla genes and are plasmid encoded. Thus, they can be easily transferred to different species of bacteria via horizontal transmission. In this study, freshwater samples were collected upstream and downstream of a water treatment plant and were tested for ESBL-producing bacteria. A total of 12 colonies were isolated and DNA extraction was performed ...
