Multi-Generational Effects Of ∆9-Tetrahydrocannabinol Exposure On Gene Expression In Liver Tissue, Kayla Lovitt
Multi-Generational Effects Of ∆9-Tetrahydrocannabinol Exposure On Gene Expression In Liver Tissue, Kayla Lovitt
Honors Theses
Cannabis is the most commonly used, cultivated, and trafficked illicit drug worldwide. Increased availability and acceptance of cannabis and cannabinoid-containing products provide the necessity for understanding how these substances influence aging. In this study, zebrafish (Danio rerio) were exposed to concentrations of Δ9-tetrahydrocannabinol (THC) (0.08, 0.4, 2 µM) during embryonic-larval development, the effects on aging were measured 30 months later and in the offspring of the exposed fish (F1 generation. We observed results indicating a biphasic and hormetic effect. Treatment with the lowest concentration of THC significantly increased egg production, while higher concentrations resulted in impaired …
The Impact Of E-Cigarette Smoking On Pulmonary Responses To Maximal Exercise, Chelsea N. Robinson
The Impact Of E-Cigarette Smoking On Pulmonary Responses To Maximal Exercise, Chelsea N. Robinson
Masters Theses, 2020-current
Electronic cigarettes (e-cigarettes) have emerged as popular alternatives to smoking conventional tobacco, particularly in a younger demographic. However, there is emerging and conflicting evidence on the magnitude of airway damage with e-cigarette usage. While evaluating airway health can be challenging, using a stimulus such as exercise may be used to elucidate the effects of e-cigarettes on the pulmonary system. Purpose: To determine the impact of an acute maximal exercise on changes in pulmonary function (i.e. bronchodilation and bronchoconstriction) in young adult exclusive e-cigarette smokers (S) compared to nonsmokers (NS). We hypothesized that S will have lower post-exercise bronchodilation after an …
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
Theses and Dissertations
Patients with severe lung pathologies, such as Acute Respiratory Distress Syndrome (ARDS), often require mechanical ventilation as a clinical intervention; however, this procedure frequently exacerbates the original pulmonary issue and produces an exaggerated inflammatory response that potentially leads to sepsis, multisystem organ failure, and mortality. This acute lung injury (ALI) condition has been termed Ventilator-Induced Lung Injury (VILI). Alveolar overdistension, cyclic atelectasis, and biotrauma are the primary injury mechanisms in VILI that lead to the loss of alveolar barrier integrity and pulmonary inflammation. Stress and strains during mechanical ventilation are believed to initiate alveolar epithelial mechanotransduction signaling mechanisms that contribute …
