Cocaine, Cocaethylene And Ethanol In Postmortem Blood Submitted To The New York City Office Of Chief Medical Examiner, Jada T. Alexis

Student Theses

Cocaine overdose deaths are on the rise in the United States. This increase may be due to the co-consumption of cocaine with other drugs. When cocaine is ingested in conjunction with alcohol, a specific metabolite called cocaethylene forms. Information regarding cocaethylene, specifically its interpretive value in post-mortem cases, has not been widely studied. Data from the Office of the Chief Medical Examiner in New York City revealed that there were 195 cases in 2017 positive for cocaethylene. These cases were most likely to involve black (42.1%) males (79.5%) in Manhattan (28.2%) aged 50 - 59 (34.4%). Most of the cases …

The Effects Of Agrochemical Pesticide Applications On Target And Off-Target Species In Aquatic Ecosystems, Bryan K. Delius

USF Tampa Graduate Theses and Dissertations

The increase in the global human population is driving agricultural expansion, which increases the likelihood and degree by which agrochemicals impact aquatic systems. It is projected that by 2100 the global human population will exceed 11 billion, and to feed the increased human population, the necessary increase in agricultural infrastructure is estimated to double irrigation, nearly triple fertilizer applications, and increase pesticide applications by tenfold. It stands to reason that wetlands impacts from agriculture are also likely to increase as the industry expands its operation to meet the globally growing demand for food.

Wetlands are highly productive habitats that not …

Contemporary Brazilian Catholicism And Healing Practices: Notes On Environmentalism And Medicalization, Juliano F. Almeida

Journal of Global Catholicism

Anthropological studies on Brazilian Catholicism traditionally focused on popular variants of this religious practice and their relationship with the official Catholicism. Encouraged by recent anthropological perspectives, which highlight the relevance of devoting researches not only on the margins, but also on the center of social practices, this paper analyzes contemporary practices of Brazilian Catholic friars and priests on health promotion. The analysis of their publications (books that include practices and tips on health and that became best sellers etc.), as well as interviews, allows us to perceive a process of environmentalization on the contemporary Brazilian Catholicism. This process seems to …

Evaluating The Chronic Effect Of Food Coloring Dyes On Biological Life Functions Of Model Organism; Caenorhabditis Elegans, Demilade Adisa

Dissertations (2016-Present)

Food coloring dyes are substances known to enhance the appearance of food or drink by imparting color when it is added. They have been in large commercial food production as well as in its use in domestic food applications and non-food applications. The toxic effects of food coloring dyes have been seen in the enzymatic breakdown of the azo linkage of the dye molecule by enzyme; azo reductase. The degradation of such food dye products give rise to increased toxic effects that affect the nervous system.

Caenorhabditis elegans is a bacterial feeder, free-living soil nematode used as a model organism …

Environmentally Marginalized Populations: The "Perfect Storm" For Infectious Disease Pandemics, Including Covid-19, Gabriella Y. Meltzer, Oyemwenosa Avenbuan, Christina Awada, Oluwakemi B. Oyetade, Tricia Blackman, Simona Kwon Drph, Mph, Esther Erdei Phd, Judith T. Zelikoff Phd

Journal of Health Disparities Research and Practice

COVID-19 has exacted a severe toll on the United States population’s physical and mental health and its effects have been felt most severely among people of color and low socioeconomic status. Using illustrative case studies, this commentary argues that in addition to COVID-19 health disparities created by psychosocial stressors such as the inability to socially distance and access quality healthcare, environmental justice communities have the additional burden of disproportionate exposure to toxic contaminants that contribute to their higher risk of COVID-19. Environmental contaminants including heavy metals and persistent organic pollutants found contaminating their nearby environments can alter the immune response, …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Per- And Polyfluoroalkyl Substances In Consumable Fish & Surface Waters Near Sites Using Aqueous Film-Forming Foams: Potential Risks, Suggested Regulatory Standards And Policy Approaches For Massachusetts, Tachalla Gibeau

Sustainability and Social Justice

Per- and polyfluoroalkyl substances (PFAS) are emerging contaminants of concern with potential for adverse effects on both human and environmental health. Hence, long-chain PFAS compounds used in legacy aqueous film-forming foams (AFFFs) are being phased out, resulting in the stockpiling of them at various commercial installations. PFAS contaminated runoff from these facilities has the potential to contaminate nearby surface water bodies and the fish inhabiting them. An analytical approach was used to identify surface water bodies in Massachusetts that are habitats for fish susceptible to PFAS contamination and where said fish are also popularly consumed by locals – thereby representing …

Analysis Of Cannabinoids In Serum By Gc-Ms/Ms, Christie Cannarozzi

Student Theses

Due to recent changes in federal and state legislations, the availability and consumption of cannabis products have increased in the United States. The expanded use of recreational and medicinal cannabis products increases the importance of implementing sensitive and selective instrumental methods in toxicological laboratories, as legal implications may arise in forensic cases, such as driving under the influence of drugs (DUID). The purpose of this study was to perform a cross-validation for the quantitative analysis of cannabinoids (Δ9-tetrahydrocannabinol, cannabidiol, cannabinol, 11-hydroxy-Δ9-tetrahydrocannabinol, and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol) in serum by gas chromatography coupled to triple quadrupole tandem mass spectrometry (GCTQ). This method was fully …

Effects Of Mercury On The Dopamine Transporter Cell Surface Expression In Pc12 Cells, Christina Hui

Student Theses

Environmental factors, such as heavy metal exposures, have been suggested to have an impact not only on neurodegenerative disease, such as Parkinson’s disease, but also on psychostimulants abuse and their toxicity. In this study, two questions were addressed: 1) effects of mercuric chloride on parkinsonian toxicant 1-methyl-4-phenylpyridinium (MPP⁺) induced cytotoxicity and 2) effects of mercuric chloride on cell surface dopamine transporter. Pheochromocytorma cells (PC12) were treated with various concentrations of mercuric chloride (0.02~2.0 ppm) for 4 hours with and without 0.1 mM MPP⁺. Significant potentiation of toxicity was observed when there was co-treatment with 0.5 ppm …
