THE HUMAN PLASTINATION PROCESS

The 
Plastination 
Process


Even though a major German encyclopedia (the 19th edition of the Brockhaus Encyclopedia, 1992) indicates that the word "Plastination" is derived from the Greek (from plassein = to shape, to form), the term is, in fact, a creation of Gunther von Hagens. He coined the term because "plastification" already had a fixed meaning in the field of polymer chemistry, and the expression used in the original patents of 1977/78 ("Polymer Impregnation of Perishable, Biological Specimens”) was not terribly catchy and was utterly inadequate for popularizing the new technology, particularly abroad. The following will provide an explanation of how Plastination works. We will first present the process in a general, comprehensible manner; for those with an interest, we will then go into more detail regarding the chemicals and chemical processes used.

A process at the interface of the medical discipline of anatomy and modern polymer chemistry, Plastination…

HOW TO CONCEIVE A BABY BOY

How to conceive a boy

Some couples are almost desperate to conceive a baby of one particular gender. Fathers especially, can be eager to have a boy but there are also mothers who long for a son. Most couples however, are happy with either a boy or a girl baby, as long as it is healthy and strong. But if you are keen to try to sway the odds of having a boy then there is no harm in trying. Just remember that there are no guarantees and the odds of conceiving a boy or a girl are almost exactly the same for each and every pregnancy. No matter what claims are made by companies asserting their skills in predicting whether a boy or girl will be conceived, don’t be too trusting. A lot of time, money, trust and energy can be wasted by couples who think they can consciously influence their baby’s gender. It’s worth remembering that the only scientifically proven strategy which can sway the odds, just slightly, is the timing of intercourse. Diet, lunar calendars, sexual positions and even the boy…

Pregnancy Tests

A pregnancy test may let you know, one way or the other, if you are pregnant. Here are answers to some of the most common questions about pregnancy tests.

What is a pregnancy test and how does it work?
Pregnancy tests are designed to tell if your urine or blood contains a hormone calledhuman chorionic gonadotropin(hCG). This hormone is produced right after a fertilized egg attaches to the wall of a woman's uterus. This usually happens -- but not always -- about six days after fertilization. If you're pregnant, levels of hCG continue to rise rapidly, doubling every two to three days.

What types of pregnancy tests are available?
Two main types of pregnancy tests can let you know if you're pregnant: urine tests and blood tests.

 Early Signs of Pregnancy
Urine tests can be done at home or in a doctor's office. Many women first choose a home pregnancy test to take about a week after a missed periodHome pregnancy testsare private and convenient. These products …

Trichomoniasis 
Español (Spanish) Most people who have trichomoniasis do not have any symptoms. What is trichomoniasis?Trichomoniasis (or “trich”) is a very common sexually transmitted disease (STD). It is caused by infection with a protozoan parasite called Trichomonas vaginalis. Although symptoms of the disease vary, most people who have the parasite cannot tell they are infected. How common is trichomoniasis? Trichomoniasis is the most common curable STD. In the United States, an estimated 3.7 million people have the infection. However, only about 30% develop any symptoms of trichomoniasis. Infection is more common in women than in men. Older women are more likely than younger women to have been infected with trichomoniasis. Two Trichomonas vaginalis parasites, magnified (seen under a microscope) How do people get trichomoniasis?
The parasite passes from an infected person to an uninfected person during sex. In women, the most commonly infected part of the b…
