DESCRIPTION (provided by applicant): Cardiovascular disease is the leading cause of morbidity and mortality in the United States. Oxidative Stress and Inflammation play a pivotal role in atherogenesis. CANDIDATE: In the funded K24 Award (Year 4), the principal investigator has made excellent progress with respect to productivity (publications and procuring grants), mentoring and enhancing his research program. RESEARCH PLAN: In the present proposal, which aims to further strengthen his research program and mentoring in patient-oriented research, the principal investigator proposes the following studies: 1) The Effect of High dose Alpha tocopherol Supplementation on Oxidative Stress (OS), Inflammation and Carotid Atherosclerosis in Patients with Coronary artery disease ; 2) Monocyte Function and Inflammation in Type 1 Diabetes and its Modulation with Simvastatin therapy; 3) The Effect of Simvastatin Therapy on Monocytic Inflammatory Markers and hsCRP Levels in Patients with the Metabolic Syndrome; 4) A Dose-Response Effect of Lycopene supplementation on Biomarkers of OS; 5) Effect of Alpha tocopherol and Gamma tocopherol Supplementation on Biomarkers of OS and Inflammation in Patients with the Metabolic Syndrome. Biomarkers of OS that will be analyzed include urinary F2-isoprostanes, LDL oxidative susceptibility; biomarkers of inflammation will include hs-CRP, SAA, plasma soluble cell adhesion molecules, monocyte superoxide anion release, cytokine release, adhesion to endothelium. MENTORING PLAN: These focused and cohesive clinical studies in Nutrition and Metabolism, in addition to the didactic courses and Mentored Clinical Research Training Program offered at UC-Davis will provide an excellent training ground for the junior faculty and clinical fellows in the area of patient-oriented research. Thus, studies outlined in this proposal will clearly enhance the long-term objectives of the principal investigator, since his major interest is in the area of lipoproteins, oxidative stress and inflammation in diabetes and atherosclerosis and their modulation.

描述（由申请人提供）：心血管疾病是美国发病率和死亡率的主要原因。氧化应激和炎症在动脉粥样硬化形成中起着关键作用。候选人：在资助的 K24 奖（第 4 年）中，首席研究员在生产力（出版物和获得资助）、指导和加强他的研究项目方面取得了出色的进步。研究计划：在本提案中，旨在进一步加强他的研究计划和以患者为导向的研究指导，主要研究者提出以下研究：1）补充高剂量α生育酚对氧化应激（OS）、炎症的影响和冠状动脉疾病患者的颈动脉粥样硬化； 2) 1 型糖尿病中的单核细胞功能和炎症及其用辛伐他汀治疗的调节； 3）辛伐他汀治疗对代谢综合征患者单核细胞炎症标志物和hsCRP水平的影响； 4) 番茄红素补充剂对 OS 生物标志物的剂量反应效应； 5) 补充α生育酚和γ生育酚对代谢综合征患者的OS和炎症生物标志物的影响。将分析的 OS 生物标志物包括尿 F2-异前列腺素、LDL 氧化敏感性；炎症生物标志物包括hs-CRP、SAA、血浆可溶性细胞粘附分子、单核细胞超氧阴离子释放、细胞因子释放、内皮粘附。指导计划：除了加州大学戴维斯分校提供的教学课程和指导临床研究培训计划之外，这些营养和代谢方面的重点和有凝聚力的临床研究将为患者领域的初级教师和临床研究员提供一个极好的培训基地。定向研究。因此，本提案中概述的研究将明显增强主要研究者的长期目标，因为他的主要兴趣是脂蛋白、氧化应激和糖尿病和动脉粥样硬化炎症及其调节领域。
