Genetic Engineering *HTML**FONT SIZE=2 PTSIZE=8*However, if the problems of today and the need to remember historical atrocities in genetics are important, it is just as critical to plan ahead. The next 100 years will see changes more dramatic than the 20th century, which saw the creation of molecular genetics, the rise and fall of eugenics, and the creation of a U.S. and international human genome mapping effort. It is time, I believe, to use some imagination to think about what might come to be in the world of genetics in the next 100 years. Only by looking at the long-term outcomes of our current genetic research will we see the compelling need to confront the most basic questions posed by genetic medicine. And, in any event, it is no more dangerous to exercise a little imagination about our future than it is dangerous to fail to be prescient about possible surprises, such as human cloning.*/FONT**FONT SIZE=3 PTSIZE=10**BR* *BR* */FONT**FONT SIZE=2 PTSIZE=8*One shape in the crystal ball is not difficult to discern.

vanishing twin essays

vanishing twin essays The Vanishing Twin Syndrome happens when one of the twin fetuses disappears from the mothers womb while she is pregnant, which usually result in a single birth. What actually happens to the fetus is that it spontaneously aborts normally during the first trimester and the fetal tissues is absorbed by either the other twin, the placenta, or the mother, which makes the fetus looks like it has vanished. Since there isnt really a clear cause for most miscarriages there are also not always reasons or explanations for one of the fetus to spontaneously abort. In some situations the fetus may have some type of chromosomal or placental abnormalities, which may cause it to abort. A problem with the umbilical implantation may also play a role in VTS. Scientists studies have shown that 1 in 8 people start their life with a twin but only 1in 70 actually become a twin. Studies have also shown that 80% of twin pregnancies result in the lost of one or both of the babies. Even though the loss of a ba by for a multiple pregnancy is high the Vanishing Twin Syndrome occurs in 21-30% of multiple pregnancies. In the recent years there has been more incidences of the Vanishing Twin Syndrome not because it wasnt happening so much before but because of the fact that modern technogly has advanced which allows it to detect more of these cases. In the past, many women experienced Vanishing Twin Syndrome without ever knowing it. When this syndrome occurs in pregnant women the mother may not have any symptoms at all but if they do they may have mild cramping, bleeding or pelvic discomfort. In most cases when the fetus has aborted, neither the mother nor the remaining parts of the fetus receives any kind of medical treatment. If VTS occurs in the first trimester the mother would go on as usually and deliver the other baby. However in some cases the fetus may die in the second or third trimester and the surviving baby may develop ce ...
