Targeted Delivery Of Anti-Inflammatory And Anti-Oxidant Drugs For Treatment Of Chronic Obstructive Pulmonary Diseases, Yun Xiang
All Dissertations
Chronic obstructive pulmonary disease (COPD) was found to be the fourth leading cause of death in 2004, but current treatments can only relieve the symptoms and improve the quality of life for the patients. Glucocorticoids have been broadly applied in other inflammatory conditions with promising therapeutic effects, but performed poorly in COPD. The phenomenon called glucocorticoid resistance is responsible for glucocorticoid insensitivity in COPD. Researchers have proven that elevated oxidative stress in the lung of a COPD patient is one of the main causes of blocking the function of glucocorticoids. We hypothesize that reducing the oxidative stress in the lung …
Antioxidant Effect Of Peach Skin Extracts From 13 Varieties Of South Carolina Grown Peaches, Yueyuan Zhang
Antioxidant Effect Of Peach Skin Extracts From 13 Varieties Of South Carolina Grown Peaches, Yueyuan Zhang
All Theses
South Carolina is the second largest peach producing state in the United States. Every year, large quantities of peaches do not meet the fresh peach standard and are discarded or used for further processing. The waste stream from discarded and processed peaches includes the skin and this could be recovered as a rich source of antioxidants. The objective of this research was to determine the antioxidant (phenolic) content and antioxidant capacity of peach skin from various peach varieties grown in South Carolina. Chapter 1 is a literature review which covers topics of oxidation in foods, mechanism of lipid oxidation, antioxidants …
Improved Oxidative Stability In Biodiesel Via Commercially-Viable Processing Strategies, Gregory Lepak
Improved Oxidative Stability In Biodiesel Via Commercially-Viable Processing Strategies, Gregory Lepak
All Theses
Biodiesel made from waste cooking oil (WCO) frequently requires antioxidants to meet oxidation stability specifications set forth in ASTM D6751 or EN 14214. In contrast, unrefined cottonseed oil (CSO), containing tocopherols and high concentrations of gossypol, a toxic polyphenolic antioxidant, is unique for biodiesel processing because it produces biodiesel resulting in higher oxidation stability. During biodiesel production, however, only a portion of these endogenous natural antioxidants are suspected to be retained. Because the economics of biodiesel manufacturing rely upon inexpensive sources of triglycerides, emphasis was placed upon developing improved alternative commercially-viable processing strategies where WCO is the main source of …
