Patent number: 5855892Abstract: A method of altering the concentration of cholesterol constituents in human blood is provided. A daidzein material is administered to a human to increase the concentration of HDL-cholesterol and to decrease the level of LDL-cholesterol in the blood. The daidzein material may be administered in a pharmaceutical composition, or in a dietary supplement, including soy protein based dietary supplements. Utilization of daidzein to increase the concentration of HDL cholesterol and to decrease the concentration of LDL-cholesterol in the blood reduces the risk of atherosclerosis and vascular disease by providing more health beneficial HDL-cholesterol and reducing the level of atherosclerosis-inducing LDL-cholesterol.Type: GrantFiled: September 19, 1997Date of Patent: January 5, 1999Inventors: Susan M. Potter, Edna C. Henley, Doyle H. Waggle

Patent number: RE42961Abstract: Atrial arrhythmias, a major contributor to cardiovascular morbidity, are believed to be influenced by autonomic nervous system tone. The main purpose of this invention was to highlight new findings that have emerged in the study of effects of autonomic nervous system tone on atrial arrhythmias, and its interaction with class III antiarrhythmic drug effects. This invention evaluates the significance of sympathetic and parasympathetic activation by determining the effects of autonomic nervous system using a vagal and stellar ganglions stimulation, and by using autonomic nervous system neurotransmitters infusion (norepinephrine, acetylcholine).Type: GrantFiled: January 28, 2005Date of Patent: November 22, 2011Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventor: Marc Mounir Rahme
