Common Disorders of the Canine Liver. Vessel Abnormalities: In young dogs, one of the most common liver disorders is a birth defect called congenital portosystemic shunt. In these cases, a blood vessel is present that bypasses the liver, causing a buildup of toxins that the liver would normally take care of.
Chiastic structure, or chiastic pattern, is a literary technique in narrative motifs and other textual passages. An example of chiastic structure would be two ideas, A and B, together with variants A' and B', being presented as A,B,B',A'.
Any atom in an organic molecule that is bonded to four different types of atoms or chains of atoms can be considered chiral. If a carbon atom (or other type of atom) has four different substituents, that carbon atom forms a chiral center (also known as a stereocenter). Chiral molecules often have one or more stereocenters. When drawing molecules, stereocenters are usually indicated with an asterisk near the carbon.
