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.
The sickle cell gene causes the body to produce abnormal hemoglobin. In sickle cell disease, the hemoglobin clumps together, causing red blood cells to become stiff and develop a C-shaped (âsickleâ) form. These sickled red blood cells can block blood vessels, reducing blood flow in many parts of the body.
