Macrocytosis is a condition where red blood cells are larger than normal. [1] These enlarged cells, also known as macrocytes, are defined by a mean corpuscular volume (MCV) that exceeds the upper reference range established by the laboratory and hematology analyzer (usually >110 fL). [ 2 ]
Macrocytic anemia is a class of anemia characterized by the presence of predominantly larger-than-normal red blood cells (RBC, also known as erythrocytes) accompanied by low numbers of RBC and often also with insufficient hemoglobin content per cell. Macrocytic anemia occurs when – despite the larger cell size – such factors result in ...
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
Megaloblastic anemia is a type of macrocytic anemia. An anemia is a red blood cell defect that can lead to an undersupply of oxygen. [1] Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. [2] When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M ...
Runner's macrocytosis is a phenomenon of increased red blood cell size as a compensatory mechanism for increased red blood cell turnover. The impact forces from running can lead to red blood cell hemolysis and accelerate red blood cell production. This can shift the ratio of red blood cells towards younger, larger cells.
Instead of being able to calmly focus on her chemotherapy treatment, Arete Tsoukalas had to spend hours on the phone arguing with her insurer while receiving infusions in the hospital.
It can describe an increase in the number of red blood cells [1] ("absolute polycythemia") or to a decrease in the volume of plasma ("relative polycythemia"). [2] Absolute polycythemia can be due to genetic mutations in the bone marrow ("primary polycythemia"), physiologic adaptations to one's environment, medications, and/or other health ...
Sperm can linger in the vas deferens, and it can take about 15 ejaculations to clear it out (or a couple of months). He urges patients to get a semen analysis after two or three months to make ...
