| The LDL cholesterol and HDL are independent |
| 2008-07-08 07:19:41 |
1) The LDL cholesterol to distribute the cells. And this function is positive.2) Unfortunately, during this function, part of LDL cholesterol deposits on the inner walls of arteries forming plaque.3) The lipoprotein HDL removes excess cholesterol from the wall of the arteries and back to the liver.From these three points is obvious that LDL cholesterol and HDL are independent, the HDL not "destroy" the LDL, but the show lipoprotein HDL cholesterol to the liver. Having high cholesterol HDL allows you to reduce the negative effect dell'LDL in the formation of plaques. To understand better, two analogies:The analogy of food - food is essential for survival, but if they eat too ingrassiamo. Cholesterol is essential f...

| The Cholesterol Risk |
| 2008-07-08 07:18:14 |
According to the analogy is simple enough to understand that a value of total cholesterol in the blood (cholesterolemia) higher than normal is not in itself worrying, especially if there are no other cardiovascular risk factors (LDL lipoprotein, however, cause a cell proliferation that can restrict the lumen of the arteries), if necessary to distinguish between bad cholesterol (LDL lipoprotein tied) and good cholesterol (HDL linked to). The old interpretation considered optimal values those less than 240 mg / dl total cholesterol (200 mg / dl or even 160 mg / dl if there are cardiovascular risk factors or is already in place a coronary artery disease) and less than 160 mg / dl LDL cholesterol (130 mg / dl to 100 mg / dl in the case of risk factors or ...

Acting on the mechanism of production. There are several roads that pass through all the power. Caution though: we should not confuse these solutions with that of treating the power to lower cholesterol made by food. The power can control the production of endogenous cholesterol! Recalling the first that:a) cholesterol precursors are glicidib) the synthesis of cholesterol in the liver is controlled dall'enzima HMG-CoA reductase-which in turn is activated dall'insulina,we see some solutions1) using natural substances that can inhibit HMG-CoA reductase-(such as green tea). This solution is among the most optimistic, because no natural substance is so powerful as to be a cholesterol lowering drug. It should be remembered that inhibition dell'HMG-CoA redu...

| The high cholesterol protects against cardiovascular disease? |
| 2008-06-14 21:17:44 |
Apparently microorganisms play an important role in cardiovascular disease. They can be one of the factors that begin the process lesionando the endothelium arteriale. A second role role can be inferred by the association of cardiovascular disease and acute infection. The infectious agent may preferably be located in parts of the arterial walls that were previously damaged by other agents, starting a local coagulation and the creation of a thrombus (clot) and thus create an obstacle to the bloodstream. But if so, the high cholesterol may protect against cardiovascular disease rather than be the cause!In any case, the idea of the diet for the heart, with its demonization of the cholesterol, is obviously in conflict wi...

For almost 50 years we know that plant stanols and sterols, also called phytosterols and phytostanols, lowering the level of cholesterol in the blood partly blocking the absorption of cholesterol intestines. Today they are widely available in a variety of products for those who want to lower their cholesterol levels. Sterols and plant stanols have a structure very similar to that of cholesterol. The sterols are found naturally in small amounts in many fruits, vegetables, nuts, seeds, pulses, vegetable oil and other vegetable sources and are essential components of cell membranes of plants.In the same foods are also traces of stanols, but these are produced for commercial use for hydrogenation by plant sterols. People who follow a typical Western diet,...

The cholesterol as a risk factorMost of the studies on men young and middle-aged has identified high cholesterol as a risk factor for coronary insufficiency, apparently in contradiction with the idea that instead it is protective. Because high cholesterol is a risk factor in men young and middle-aged? A likely explanation is that at that age men are often at the top of his professional career. The high cholesterol may therefore indicate mental stress, because well-known cholesterol and high risk factor for heart disease. In this case, the high cholesterol is not necessarily the direct cause but it could be only one indicator. The high cholesterol in men young and middle-aged could, for example, reflect the needs of the body for further cholesterol bec...

Evidence laboratoryThe studies in the laboratory are essential to better understand the mechanisms through which lipids exert their protective function. One of the first to study this phenomenon was Dr Sucharit Bhakdi the Institute of Medical Microbiology, University of Giessen, Germany (Institut für Mikrobiologie Medizinsche, Justus-Liebig University Gießen), together with his team of researchers from various German and Danish institutions. The toxin-of Staphylococcus aureus is the most toxic substance produced by the family of bacteria that predispose to disease such staphylococci. It can destroy a wide variety of human cells, including red blood cells. For example, adding small amounts of the toxin in a test tube with red blood cells in a saline sol...

Syndrome Smith-Lemli-OpitzAs discussed in The Cholesterol Myths , there is considerable evidence to support the theory that people born with very high cholesterol, high cholesterol family are protected against infection. But if born with high cholesterol protects against infection, born with low cholesterol should have an opposite effect. Indeed it seems that is precisely the case.Children with the syndrome Smith-Lemli-Opitz have a very low cholesterol because the enzyme necessary for the last phase of the synthesis of cholesterol in the body is not working as it should. Most children with this syndrome is born dead or died shortly after birth due to serious malformations of the central nervous system. Children who survive are mentally retarded, have a v...

Cholesterol and chronic heart failureA cardiac disease can lead to a weakening of the heart muscle. A weak heart means that less blood, and therefore less oxygen, is brought to the arteries. To compensate for the power decreased, the heartbeat rises, but if the malanno is serious this is not enough. Patients with heart failure remains serious wind because the tissues receive too little oxygen, pressure is growing in their pots because the heart can not pump blood with sufficient power and become oedematous, that there is fluid that accumulates in the legs and even more serious cases in the lungs and other parts of the body. This condition is known as heart failure or chronic congestiva.There are many indications that the bacteria or other microorganis...

Low Cholesterol and HIV / AIDSA man young, unmarried with liver disease or a sexually transmitted disease, runs a much greater risk of contracting the infection of HIV. Researchers in Minnesota, headed by Dr's. Ami Claxton, followed individuals of this type for 7-8 years. After excluding those who became HIV-positive during the first four years, had been with a group of 2446 men. At the end of the study, 140 of these people were HIV positive, while that at the beginning of the study had low cholesterol were twice as those with higher cholesterol.

The high cholesterol protects against infectionsThere are many studies that have found as a low cholesterol is in some respects worse than a high cholesterol. For example, in 19 large studies involving more than 68,000 dead, examined by Professor David R. Jacobs and his staff of the Division of Epidemiology at the University of Minnesota, a low cholesterol indicates an increased risk of death for gastrointestinal and respiratory diseases [3]Most of the gastrointestinal and respiratory diseases has an infectious. Therefore an important question is whether the infection to lower cholesterol or whether it would be a lowering of cholesterol to prepare to infection. To give an answer Professor Jacobs and his group, together with Dr. Carlos Iribarren, follo...

People with high cholesterol are those who live longer. Having undergone a brainwashing argument can sembrarci so incredible to take a long time to be assimilated and fully understand its importance. Yet the fact that individuals with high cholesterol live more clear by many scientific studies.

| Cholesterol and triglycerides |
| 2008-06-14 21:07:10 |
The cholesterol, triglycerides along with phospholipids are the fat content in our body. The phospholipids are major components of cell membranes and sheaths of the nerves. The triglycerides represent the largest reserves of our lipids and represent almost 90% of the fat ingested. Cholesterol is an essential component of cell membranes and of bile. Origin of circulating fatsThe most important part of fats circulating is produced by the body itself, while another part is introduced with the diet. The absorption of dietary fat occurs at the level of the small intestine, through the work of certain enzyme systems after an emulsion with bile salts.The internal summary of lipids occurs primarily in the liver. The triglycerides are produced from carbohydrat...

A high value of cholesterolemia is only an index of suspicion for a high cholesterol. It is necessary to control other parameters and any clinical signs for diagnosticarla.The high cholesterol is one of six diseases lipidemiche, a lack of receptors in cell membranes, which are responsible for the exchange between lipoprotein cholesterol and cell. It happens usually in old age (as eg. Even diabetes mellitus II)Clinically the disease manifests itself for xantomi tendinosi, xantelasmi and arcus lipoides cornae (a halo around the pupil). Of the metabolic parameters are typical for high cholesterol: * Low density lipoproteins (LDL) senior * Very low density lipoproteins (VLDL) normal * Beta-lipoprotein high * Normal or high triglyceridesLike other three of the six diseases of th...

The study VERA (see sources) product in 1993, has shown that there is no correlation between consumption of cholesterol (milk, cream, eggs, butter, animal fats, etc..) And cholesterolemia.The report smentirebbe widespread opinion that the primary cause of high cholesterol is in the diet. A person consumption foods full of saturated fats and hydrogenated oils inevitably produce more cholesterol.The statins inhibit the production of further cholesterol in the liver that occurred during the digestion of fatty foods, bringing ...

How Timio M: Stress and heart disease, Lombardo, Rome, 1980 showed in his famous study, there is a strong correlation between stress and cholesterolemia.It seems that the cholesterolemia increases with increasing typical of stress hormones: adrenaline, noradrenaline and cortisol. It seems that the cortisole promotes lipolysis (which increases the trigliceridemia) and at the same time inhibit the development of LDL by the liver (which increases cholesterolemia and worsens the report HDL / LDL).The data were repeatedly confirmed by other authors, among them the renowned cardiologist Rosenman RH: Psycological Influence on the Variability of Plasma Colesterol, Homeostasis, 1993/34: 129 to 136. In this spirit is called into question the care with medicines made...

The reference values for the parameters doctors are normally collected from a sample of healthy people. Del parameter detected are determined simple arithmetic mean me σ x standard deviation, a measure for the dispersion of individual values. The reference value is usually m ± 2 x σ which includes about 97% of the population healthy.Example: for the entire German population is m = 210, σ x = 15%: thus the range of normal values will be 210 + - 30% = 150 to 270 ml / dl. Because these values "normal" are too high for the determination of optimal levels of cholesterolemia Consensus Conference in 1984 and in subsequent guidelines ATP has preferred to follow the criterion of risk of CHD, which are considered high those values for which the coronary risk is high.

When it comes to medicine "cholesterol" not mean the cholesterol chemical (this is an ambiguity exemplification), but in fact speaks of a class of lipoprotein (chylomicron, aggregates of transport) circulating in the blood: the relative concentration is called cholesterolemia. According to their composition in cholesterol, phospholipids, proteins, triglycerides and fatty acids, these aggregates are further divided into different classes (classificabilità laboratory according to their specific gravity between 0.98 and 1.17 g/cm3): VLDL, IDL, LDL, and HDL2 HDL3.

Cholesterol is a steroid, that is a lipid molecule consists of four rings of carbon atoms and a tail alifatica, as well as any functional groups. The structure policiclica base takes its name cyclopentane peridrofenantrene.The word cholesterol comes from the greek chole (bile) and stereos (solid), but was used for the first time in 1894. The Used to-ol stems from the fact that the C3 of the first ring of carbon [A] is a hydroxyl radical.

Cholesterol is a lipid molecule sterolica, typical of animal organisms, especially the Vertebrates. It is present in all tissues and in greater quantity in the brain, in bile and blood. Because of its structure has hydrophobic characteristics and is therefore poorly water-soluble. The intestine absorbs thanks to the bile salts.There is both a free form (35-40% of the total) is verified with long chain fatty acids. The synthesis of cholesterol takes place mainly in the liver, although many other participating bodies (adrenal gland, testis, etc. aorta.). Cholesterol is instead eliminated in the bile, transformed into bile acids and then in bile salts (from gallstones cholesterol can be obtained in pure crystalline).O...

| How Does Cholesterol Cause Heart Disease? |
| 2008-06-14 20:42:33 |
When there is too much cholesterol (a fat-like substance) in your blood, it builds up in the walls of your arteries. Over time, this buildup causes "hardening of the arteries" so that arteries become narrowed and blood flow to the heart is slowed down or blocked. The blood carries oxygen to the heart, and if enough blood and oxygen cannot reach your heart, you may suffer chest pain. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack.High blood cholesterol itself does not cause symptoms, so many people are unaware that their cholesterol level is too high. It is important to find out what your cholesterol numbers are because lowering cholesterol levels that are too high lessens the risk for de...

| 2008-06-14 20:41:41 |
An overall healthy diet can help to maintain normal blood cholesterol levels. Saturated fat, trans fats, and dietary cholesterol tend to raise blood cholesterol levels. Other types of fats, such as mono unsaturated and polyunsaturated fats can help to lower blood cholesterol levels. Getting enough soluble fiber in the diet can also help to lower cholesterol. For some people, a diet that has too many carbohydrates can lower HDL (the good cholesterol) and raise triglycerides. Alcohol can also raise triglycerides, and excessive alcohol use can lead to high blood pressure, another risk factor for heart disease and stroke....

| 2008-06-14 20:40:41 |
Being overweight or obese can raise your bad cholesterol levels. Losing weight can help you lower your blood cholesterol levels. Healthy weight status in adults is usually assessed by using weight and height to compute a number called the "body mass index" (BMI). BMI is used because it relates to the amount of body fat for most people. An adult who has a BMI of 30 or higher is considered to be obese. Overweight is a BMI between 25 and 29.9. Normal weight is a BMI of 18.5 to 24.9. Proper diet and regular physical activity can help to maintain a healthy weight. Other measures of excess body fat may include waist measurements or waist and hip measurements....

# Diet. Some foods are the types of fat that increase the level of cholesterol. These types of fats include saturated fat, trans fatty acids or trans fats, cholesterol and weight control. Saturated fat comes mostly from animal fats in the diet, but also some vegetable oils such as palm oil. Trans fats are made when vegetable oil is hydrogenated to harden. The research suggests that trans fatty acids may increase cholesterol levels. Diet cholesterol is present in foods from animal sources such as egg yolks, meat and dairy products. # Weight.

| Stem Cell Therapy for Kidney Failure |
| 2008-06-07 00:27:35 |
Renal failure or kidney failure is a situation in which the kidneys fail to function adequately. It is divided in acute and chronic forms; either form may be due to a large number of other medical problems.Biochemically, it is typically detected by an elevated serum creatinine. In the science of physiology, renal failure is described as a decrease in the glomerular filtration rate. When the kidneys malfunction, problems frequently encountered are abnormal fluid levels in the body, deranged acid levels, abnormal levels of potassium, calcium, phosphate, hematuria (blood in the urine) and (in the longer term) anemia. Long-term kidney problems have significant repercussions on other diseases, such as cardiovascular disease.Acute renal failure can be present on top of chronic renal failure. Thi...

The kidneys are complicated organs that have numerous biological roles. Their primary role is to maintain the homeostatic balance of bodily fluids by filtering and secreting metabolites (such as urea) and minerals from the blood and excreting them, along with water, as urine. Because the kidneys are poised to sense plasma concentrations of ions such as sodium, potassium, hydrogen, oxygen, and compounds such as amino acids, creatine, bicarbonate, and glucose, they are important regulators of blood pressure, glucose metabolism, and erythropoiesis (the process by which red blood cells (erythrocytes) are produced). The medical field that studies the kidneys and diseases of the kidney is called nephrologyIn humans, the kidneys are located in the posterior part of the abdomen. There is one on ea...

The lungs are very important. Energy production to aerobic respiration requires oxygen and glucose and produces carbon dioxide as a gaseous waste product, creating a need for an efficient means of oxygen delivery to cells and excretion of carbon dioxide from cells. In small organisms, such as single-celled bacteria, this process of gas exchange can take place entirely by simple diffusion. In larger organisms, this is not possible; only a small proportion of cells are close enough to the surface for oxygen from the atmosphere to enter them through diffusion. Two major adaptations made it possible for organisms to attain great multicellularity: an efficient circulatory system that conveyed gases to and from the deepest tissues in the body, and a large, internalized respiratory system that ce...
