The paintings of the Italian Renaissance differed from those of the Northern Renaissance. Italian Renaissance artists were among the first to paint secular scenes, breaking away from the purely religious art of medieval painters.
Sickle cell anaemia is caused by a genetic mutation that affects the normal development of haemoglobin. A genetic mutation is a permanent change in the normal pattern of genetic information inside all living cells. This results in one or more of the body's processes not working properly.
In sickle cell anemia, the hemoglobin is abnormal, causing the red blood cells to be rigid and shaped like a C or sickle, the shape from which the disease takes its name. Sickle cells can get stuck and block blood flow, causing pain and infections.n order for you or your child to inherit sickle cell anemia, both parents must have either sickle cell anemia (two sickle cell genes) or sickle cell trait (one sickle cell gene); read more about sickle cell trait here.
