Comparison of Ionic, Polar and Non-Polar Bonding: Whereas non-polar bonding involves the equal sharing of electrons between identical non-metal atoms, POLAR BONDING is the unequal sharing of electrons between two different non metal atoms.
Cholestasis of Pregnancy. Some women experience a very severe itching in late pregnancy. The most common cause of this is cholestasis, a common liver disease that only happens in pregnancy. Cholestasis of pregnancy is a condition in which the normal flow of bile in the gallbladder is affected by the high amounts of pregnancy hormones. Cholestasis is more common in the last trimester of pregnancy when hormones are at their peak, but it usually goes away within a few days after delivery.
Cholestasis may occur as a result of an acute or chronic process involving either the extrahepatic or intrahepatic biliary tree . This syndrome is characterized by an elevated serum alkaline phosphatase (AP) and gamma-glutamyltransferase (GGT) out of proportion to elevation of aminotransferase enzymes . Clinically, pruritus and fatigue are the most common presenting symptoms of chronic cholestatic disorders.
