Peripheral blood smear in patient with thrombotic thrombocytopenic purpura. Typical schistocytes are annotated. A schistocyte (from Greek schistos for "divided" and kytos for "hollow" or "cell") is a fragmented part of a red blood cell. Schistocytes are sometimes referred to as helmet cells because of their irregular shape from mechanical force ...
In all causes, the mechanism of MAHA is the formation of a fibrin mesh due to increased activation of the system of coagulation. The red blood cells are physically cut by these protein networks. The resulting fragments are the schistocytes observed in light microscopy Schistocytes or helmet cells
The cercaria has a characteristic bifurcated tail, classically called furcae (Latin for fork); hence, the name (derived from a Greek word κέρκος, kerkos, meaning tail). The body is pear-shaped and measures 0.24 mm in length and 0.1 mm in width. [22] Its tegument is fully covered with spine. A conspicuous oral sucker is at the tip of the body.
Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation (poly- refers to many, and -chromasia means color.)
Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections. [1] [2] A similar term is spur cells. Often they may be confused with echinocytes or schistocytes.
Increasingly, however, researchers are wondering if there is a whole-body memory, that is, if different parts of our bodies can also make and store a type of memory, and if so, how these other ...
Hemolytic anemia or haemolytic anaemia is a form of anemia due to hemolysis, the abnormal breakdown of red blood cells (RBCs), either in the blood vessels (intravascular hemolysis) or elsewhere in the human body (extravascular). [2]
Red blood cells, also called erythrocytes, are the oxygen-carrying cells. Erythrocytes are functional and are released into the blood. The number of reticulocytes, immature red blood cells, gives an estimate of the rate of erythropoiesis. Lymphocytes are the cornerstone of the adaptive immune system. They are derived from common lymphoid ...
