Mechanisms Of Synthetic Cannabinoids On Cardiovascular Health, Madeleine A. Nelson
Mechanisms Of Synthetic Cannabinoids On Cardiovascular Health, Madeleine A. Nelson
Honors Thesis
Cannabinoids encompass natural cannabis and synthetic cannabinoids. While the synthetic cannabinoids interact with the same endogenous system as cannabis, their effects are quite different and poorly understood. In addition to psychological effects that trigger their use, these substances are linked to cardiovascular morbidity. To assess the cardiovascular effect of synthetic cannabinoids, we first tested the hypothesis that intravenous administration of a synthetic cannabinoid would increase blood pressure in conscious rats. Second, we tested the hypothesis that the sympathetic nervous system is involved by injecting a ganglion blocker to see if the cardiovascular response from synthetic cannabinoids would be blocked. Third, …

Dissertations, Master's Theses and Master's Reports
Obesity is a chronic metabolic disorder associated with increased risk of cardiovascular disease. Evidence suggests that chronic intermittent fasting improves cardiometabolic health and reduces arterial blood pressure. However, the mechanisms underlying the reductions in blood pressure and improved cardiovascular health observed from chronic fasting studies remain unclear. The autonomic nervous system has a central role in the regulation of blood pressure and is essential for cardiovascular homeostasis. We conducted a study to investigate how acute fasting influences autonomic control of blood pressure at rest and during stress. Twenty-five young, healthy, normal weight, normotensive participants were tested twice, once in the …
