Associated Press. The fabled tundra of Lambeau Field will be far from frozen when the Green Bay Packers and Minnesota Vikings clash in Saturday's NFC playoff game. Temperatures are expected to be in the teens when the game starts at 7 p.m. Lambeau's underground heating system will keep the turf from freezing. Below the surface, a network of plastic pipes containing antifreeze, covered by a foot of sand, make the field of natural grass and artificial fibers playable.
Mild IUGR usually doesn't cause long-term problems. In fact, most babies with IUGR catch up in height and weight by age 2. But if severe, IUGR can seriously harm a baby before and after birth. The extent of the health problems depends upon the cause and severity of the growth restriction. It also depends upon how far along you are in the pregnancy when it develops.
Naturally acquired passive immunity occurs when maternal antibodies cross the placenta during gestation, or are passed on to a newborn via the motherâs breast milk. Immunoglobulin G (IgG) is the only antibody able to cross the placenta to the fetus. IgG is the most abundant antibody in the human body, representing about 75%â80% of all antibodies. It protects the fetus against infection during gestation and the neonate immediately after birth.
