What is Cholesterol?Cholesterol is a sterol (a combination steroid and alcohol). Cholesterol is a lipid found in the cell membranes of all tissues, and it is transported in the blood plasma of all animals. Because cholesterol is synthesized by all eukaryotes, trace amounts of cholesterol are also found in membranes of plants and fungi.The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol, as researchers first identified cholesterol in solid form in gallstones by Francois Poulletier de la Salle in 1769. However, it is only in 1815 that chemist Eugene Chevreul named the compound "cholesterine".[2]Most of the cholesterol is synthesized by the body and some has dietary origin. Cholesterol is more abundant in tissues which either synthesize more or have more abundant densely-packed membranes, for example, the liver, spinal cord and brain. It plays a central role in many biochemical processes, such as the composition of cell membranes and the synthesis of steroid hormones. Cholesterol is insoluble in blood, but is transported in the circulatory system bound to one of the varieties of lipoprotein, spherical particles which have an exterior composed mainly of water-soluble proteins. The main types, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) carry cholesterol from and to the liver.According to the lipid hypothesis, abnormally high cholesterol levels (hypercholesterolemia) and abnormal proportions of LDL and HDL are associated with cardiovascular disease by promoting atheroma development in arteries (atherosclerosis). This disease process leads to myocardial infarction (heart attack), stroke and peripheral vascular disease. As high LDL contributes to this process, it is termed "bad cholesterol", while high levels of HDL ("good cholesterol") offer a degree of protection. The balance can be redressed with exercise, a healthy diet, and sometimes medication. |

BIOMEDICAL RESULTS OF SKYLAB - Automatic Blood Pressure Measuring The Blood Pressure Measuring System measures blood pressure by the noninvasive Korotkoff sound technique on a continual basis as physical stress is imposed Sound Therapy, HoMedics Blood Pressure Monitors, Thermometers Blood Pressure Monitor · Digital Kitchen · Personal Electronics HoMedics SS-8000 iSoundSpa Max iPod Dock with Sound Machine and Remote How to measure blood pressure At the point where cuff pressure equals the systolic pressure, a sharp tapping sound is heard. We recall that the blood pressure oscillates between systolic Taking a blood pressure The first time you hear this sound, note what the reading was on the pressure gage. This value represents the systolic blood pressure (described below). High Blood Pressure: Heart and Blood Vessel Disorders: Merck An abnormal heart sound, called the fourth heart sound, is one of the earliest changes in the heart caused by high blood pressure.
