cholesterol

Hi guys, want to know about cholesterol?

here, check it out what i knew about it.

Cholesterol is a waxy fat that is present in all human beings.
About 70-80 % of the cholesterol in the body is manufactured by the liver. The rest is consumed through cholesterol-rich foods such as meat, eggs and dairy products.

Cholesterol itself is vital for survival. However, it can also contribute to coronary artery disease. To understand how cholesterol is related to heart disease, it is necessary to understand how it is transported through the body. Cholesterol is carried in the bloodstream in specialized protein packages called lipoproteins. These are comprised of another building block called apolipoproteins.
A good analogy is to think of lipoproteins like vehicles on the road, while cholesterol represents the passengers. Some of the cars are sleek and fast, while others are cumbersome, large and slow. The nature of the lipoprotein package, or vehicles, ultimately determines what will happen to the cholesterol it carries. In some cases, excess cholesterol will be transported to the liver, where it is metabolized harmlessly. In other cases, excess cholesterol will penetrate the walls of arteries throughout the body, contributing to a disease called atherosclerosis.

Although there are many subclasses of lipoproteins, researchers generally focus on the following five types:
High-density lipoproteins (HDL), which transport cholesterol away from arteries and are protective.
Low-density lipoproteins (LDL), which can penetrate the arterial wall and deposit cholesterol within the artery, thus contributing to heart disease.
Very-low-density lipoproteins (VLDL), which are similar to LDLs, but can more easily penetrate the artery wall.
Intermediate-density lipoproteins. Like VLDLs, these also carry triglycerides and cholesterol.
Chylomicrons, which carry only a small percentage of cholesterol. Chylomicrons are mostly rich in another type of fat called triglycerides.

Many studies have shown that high levels of LDLs, IDLs and VLDLs are associated with increased risk of heart attack because these lipoproteins actually harm arteries. Conversely, higher levels of HDLs protect against heart attack because these lipoproteins remove potentially dangerous cholesterol from the blood stream. Thus, modern cholesterol management tends to focus on reducing LDLs while increasing HDLs. The National Cholesterol Education Program classifies cholesterol levels as follows (all measurements are in milligrams per deciliter):
Total cholesterol levels less than 200 are desirable.
Total cholesterol levels between 200 and 239 are borderline-high.
Total cholesterol levels that are 240 or higher are high.
HDL levels of less than 40 for men and 50 for women are considered low, and levels of 60 or more are considered protective against heart disease.
HDL levels should be 40 or above (the American College of Cardiology recommends levels of 45 or above for women).
LDL levels should optimally be less than 100 (levels greater than 129 are considered borderline-high, and levels greater than 159 are considered high).

careful to eat your meat, be healthy, be life.

Chicken Pox

Chicken pox is not a type of food like fried-chicken, but it's a childhood disease.
In Indonesia language known as cacar air.
Chicken pox mostly affected nearly all children under the age of ten years in all the world. but, sometimes when somebody didn't get chickn pox when he is as a child, chicken pox could affected her or him as adult. A person can only get chicken pox once in a life. When an adult gets chicken pox, the case is usually more severe and lasts longer. Adults are 10 times more likely than children to require hospitalization from chicken pox. Adults who have had chickenpox as a child are less likely to have shingles in later life if they have been exposed occasionally to the chickenpox virus (for example by their children). In the late 1980s, American children were a reported 3.9 million cases of chicken pox each year .
Chicken pox is highly contagious. In England and Wales, 75% of deaths due to chickenpox are in adults. A person with chicken pox is contagious from one to two days before the outbreak of the chicken pox rash, and for six days after the rash erupts. After being exposed, a person will show symptoms of chicken pox within 10-21 days.

Chicken pox caused by the virus named varicella zoster virus.
Symptoms of the disease include a mild fever for one to two days before the appearance of a skin rash (small, watery blisters) that begins on the scalp and body and spreads within three to four days over the entire body.
A typical case of chicken pox involves between 250 and 500 blister over the body. These dry into scabs after three or four days. The blisters are very itchy, and children should be discouraged from scratching and their fingernails should be kept very short for the duration of the chicken pox case. to help relieve the itching of chicken pox usually can using lotion or body powder.
Although complications from chicken pox are generally uncommon, the most common one is bacterial infection of the skin, initiated at the site of a chicken pox blister that has broken or was scratched open. Other complications include viral or bacterial pneumonia and encephalitis (swelling of the brain).
The groups that are at higher risk for developing complications are anyone with a weak immune system, children with lung diseases, children with eczema or other skin conditions; infants under one year of age; premature infants whose mothers have not had chicken pox; and newborns whose mothers had chicken pox around the time of delivery. An oral anti-viral drug, acyclovir, may be prescribed for anyone at risk of developing a severe case of chicken pox. Acyclovir is only effective if it is given within 24 hours of the outbreak of the chicken pox blisters.

Shingles, known medically as herpes zoster, is a condition of the nerves caused by the chicken pox virus that affects between 10-20% of all people who have ever had chicken pox. Once a person has had chicken pox, the virus remains in his or her nerve roots for the rest of his or her life. The virus most commonly reappears as shingles at age 50 or older, although shingles can occur anytime. Shingles cause itching, numbness, or severe pain in skin areas where the affected nerve root is located, and within about three days, causes clusters of blisters to form along the affected nerve. The blisters last two to three weeks.

BE (Breath Exercise)

Are you:
a women ?
a Man ?
a student ?
a worker ?
a house-wife?
a doctor ?
a director ?

whatever you are, whatever you do, i think all of us sometimes feel distress.
working under pressure, under dateline, less income, or something happends out of what we want, .....

remember to do this :
- close your eyes
- take a deep breath slowly, hold your breath for a few seconds and then release slowly.
taking a “deep breath” here means breathing in air through the nose to fill the lower part of the lungs, then the middle part and then the upper part. “Releasing” a breath means exhaling all of the stale air from the lungs through the mouth before taking in another fresh breath .
Do it minimum for 6 times.

If it's the first time you do this breath exercise, when you hold your breath , you may feel a bit uncomfortable in your chest.
but after that you get relax and may be surprised to find yourself getting more work done, with better quality.

Breathing is something most people take for granted. However, most of us do not realize that when we are under stress we tend to hold our breath or take short, shallow breaths.

Limiting our intake of oxygen can have far reaching effects on the body, because oxygen is the most important nutrient for the heart, brain and every other major organ of the body, .
That's why, breathing exercises can be very helpful for reducing stress, relaxing and rejuvenating the body as well as the mind.
