Animals and animal models have been invaluable for our current understanding of human and animal biology, including physiology, pharmacology, biochemistry, and disease pathology. However, there are increasing concerns with continued use of animals in basic biomedical, pharmacological, and regulatory research to provide safety assessments for drugs and chemicals. There are concerns that animals do not provide sufficient information on toxicity and/or efficacy to protect the target population, so scientists are utilizing the principles of replacement, reduction, and refinement (the 3Rs) and increasing the development and application of new approach methods (NAMs). NAMs are any technology, methodology, approach, or assay used …

The E-Liquid Flavorings Cinnamaldehyde, Vanillin, And Ethyl Vanillin Induce Cellular Stress Responses In Human Proximal Tubule (Hk-2) Epithelial Cells, Ashley J. Cox
Theses, Dissertations and Capstones
The use of electronic nicotine delivery systems (ENDS) has become popular in recent years as an alternative to traditional cigarettes. These devices heat and subsequently vaporize e-liquids for inhalation by the user, which allows for the delivery of ingredients such as flavorings, nicotine, and solvents through the vapor. Flavorings used in e-liquids are “generally recognized as safe” (GRAS) for consumption by the Food and Drug Administration (FDA), however there are currently no recommendations on safety regarding the inhalation of flavoring agents. While research characterizing effects of e-liquids and their flavorings is abundant in lung and respiratory tract models, few studies …

Exposure To Dithiocarbamate Fungicide Ziram Results In Hepatic And Renal Toxicity In Long-Evan Rats, Jeffrey Chen
Theses and Dissertations
Ziram is a broad spectrum fungicide that is used on a variety of crops. It has been shown to display a wide array of toxicological effects, however, there is still a scarcity of mechanistic data regarding how it facilitates those effects. One of its presumed mechanisms of toxicity is due to the production of oxidative stress. However, whether the production of oxidative stress is due to its dimethyldithiocarbamate backbone, its metal moiety, or a combination of both, is still unknown. Contributing to the production of oxidative stress is ziram’s ability to alter essential metal homeostasis through transchelation of other essential …
Determination Of Genetic Variation In Opioid-Resistant Hospice Patients Using A Pharmacogenomics Approach,

Determination Of Genetic Variation In Opioid-Resistant Hospice Patients Using A Pharmacogenomics Approach, Daniel Bianculli
Theses and Dissertations
Managing pain requires a delicate balance between the advantages of opioid analgesia and the possible adverse effects. This balance becomes even more difficult in hospice and palliative care environments where dosage regimens are frequently ambiguous. Some hospice patients experience opioid resistance, in which opioids no longer produce an analgesic effect on a patient. Evidence-based analyses frequently omit this vulnerable population, resulting in a need for concrete procedures. The emergence of pharmacogenomic analysis and personalized treatment presents a solution to this problem by using each patient's genomic data to interpret opiate dosing. This pharmacogenomic study aimed to single nucleotide polymorphisms (SNPs) …

Evaluation Of Microglia’S Structural Variations Within An Organotypic Hippocampal Slice Model After Regionalized Toxic Injury, Jesus Antonio Trejos
Theses and Dissertations
The dendritic cells of the CNS, the microglia (MG), are an initiation point of the immunological response within the post blood-brain barrier (BBB) compartment. Microglia morphology drastically changes in response to cell stress to a much different non-dendritic morphology. This investigation postulates that if the first MG responses to toxic injury are isolated and studied in greater morphological detail there is much to be learned about MG metamorphosis from a baseline (M2) to an activated (M1) state. The organotypic hippocampal slice was the experimental setting used to investigate microglial response to toxic injury. This isolates dendritic cellular responses and associated …

The Effects Of Alcohol On Crash Avoidance Reaction Time In A Driving Simulator Task In Humans, Aishwarya Vasudevan
Wayne State University Theses
AIM 1: Alcohol-impaired driving continues to be a significant cause of car crash injuries and deaths. The blood alcohol concentration (BAC) cut-off level for drunk driving is 0.08% in Michigan, and is estimated that lowering this cut-off to 0.05%would save 500–800 lives every year in the US alone. We used a portable virtual reality (VR)-based driving simulator to demonstrate the effects of alcohol at BAC concentrations 0.02-0.08%, grouped into 0.01% increments, on driving performance, specifically Crash Avoidance Reaction Time (CART), i.e., the time (in msec) required to initiate a steering avoidance response. We found that BAC concentrations as low as …

Theses and Dissertations
Pulmonary fibrosis (PF) poses a significant challenge in respiratory medicine due to its complex etiology and progression characterized by excessive lung scarring, leading to compromised pulmonary function. The multifaceted roles of Vascular Endothelial Growth Factor A (VEGF-A) and specifically its isoform VEGF-A165 are critical in this context, given their involvement in angiogenesis, lymphangiogenesis, and tissue repair. The dual nature of VEGF-A165, promoting angiogenesis and potentially exacerbating or mitigating fibrosis, underscores its significance in both the progression and recovery phases of PF. Our work, explores the nuanced functions of VEGF-A165 using AAV1 as a gene delivery vector to overexpress this growth …
