Single function switches are the most commonly used adaptive switches. This type of switch performs one function (i.e., on/off) this switch has only one function - on or off.

Echinocytes and keratocytes should be considered in the differential diagnosis of spur cell anemia. Echinocytes or burr cells are spiculated red blood cells with uniform, narrow, spikelike surface projections. Spur cells have fewer spicules, and the spicules vary more in size than echinocytes. Keratocytes are acanthocytelike cells with bizarre shapes and horny projections. Differential Diagnoses.
a type I transmembrane protein present on thymocytes, T cells, granulocytes, monocytes, natural killer cells, platelets, brain, activated B cells, plasma cells, and hemopoietic stem cells that serves as a ligand for CD54 and facilitates cell-cell adhesion; expressed on some myelomas and lymphomas.hen considering the diagnosis of myeloid sarcoma, an appropriate panel of stains includes several immunohistochemical stains and special stains, specifically CD34, , lysozyme, myeloperoxidase, CD68 (monocyte marker), CD163 (monocyte marker), and CD117 (3, 4, 6).
