Drug therapy is warranted for many dogs with liver disease. Glucocorticoids (âsteroidsâ) have been used to prolong survival times in dogs with liver disease due to their anti-inflammatory and immunosuppressive properties, although their use and appropriate dosage protocols are somewhat controversial.
chiasma. pl. chiasmata [L., Gr.] chiasm; in genetics, the points at which members of a chromosome pair are in contact during the prophase of meiosis and because of which recombination, or crossing over, occurs on separation.
A chiasma is a point of contact between sister chromatids that forms during meiosis, a process of cell division and replication used by a wide variety of organisms.t the chiasma, the chromatids can exchange genetic information, resulting in new combinations of genetic material. When the chromatids separate and become sister chromosomes, they will contain a different mix of genetic material than their parent chromosomes.
