Erythroblasts
|
D004900 |
[Immature, nucleated ERYTHROCYTES occupying the stage of ERYTHROPOIESIS that follows formation of ERYTHROID PRECURSOR CELLS and precedes formation of RETICULOCYTES. The normal series is called normoblasts. Cells called MEGALOBLASTS are a pathologic series of erythroblasts.

Erythrocebus
|
D016669 |
[a genus of Old World monkeys of the family CERCOPITHECINAE that inhabit the forests and savannas of Africa. It contains only one species, ERYTHROCEBUS PATAS, also known as the patas monkey or red monkey.

Erythrocebus patas
|
D004901 |
[A species of the genus ERYTHROCEBUS, subfamily CERCOPITHECINAE, family CERCOPITHECIDAE. It inhabits the flat open arid country of Africa. It is also known as the patas monkey or the red monkey.

Erythrocruorins
|
D004902 |
[High molecular weight (1,500,000 to 3,000,000) hemoglobins found in the plasma of many polychete and oligochete annelid worms, crustaceans, insects, and mollusks. They bind one mole of oxygen per heme and function as oxygen carriers.

Erythrocyte Aggregation
|
D004903 |
[Aggregation of ERYTHROCYTES in vivo, caused by specific interactions such as those induced by antibodies.
, The clumping of ERYTHROCYTES that is like a stack or roll of coins.
, The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
, Clumping of ERYTHROCYTES, in vivo, in intact blood vessels. Increased and/or abnormal aggregation may lead to impairment of MICROCIRCULATION (blood sludging and THROMBUS formation) and development of VASCULAR DISEASES.

|
Erythrocyte Aging
|
D004905 |
[The senescence of RED BLOOD CELLS. Lacking the organelles that make protein synthesis possible, the mature erythrocyte is incapable of self-repair, reproduction, and carrying out certain functions performed by other cells. This limits the average life span of an erythrocyte to 120 days.
] |
|
Erythrocyte Count
|
D004906 |
[The number of RED BLOOD CELLS per unit volume in a sample of venous BLOOD.
] |
|
Erythrocyte Deformability
|
D004907 |
[Ability of ERYTHROCYTES to change shape as they pass through narrow spaces, such as the microvasculature.
] |
|
Erythrocyte Inclusions
|
D004908 |
[Pathologic inclusions occurring in erythrocytes.
] |
|
Erythrocyte Indices
|
D004909 |
[A measure of the variability in size of circulating ERYTHROCYTES. It is expressed as the coefficient of variation of the erythrocyte volume.
, MCH is the HEMOGLOBIN divided by the ERYTHROCYTE COUNT.
, MCHC equals HEMOGLOBIN divided by HEMATOCRIT.
, MCV equals HEMATOCRIT divided by ERYTHROCYTE COUNT.
, ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT. The indices include the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the mean corpuscular hemoglobin concentration (MCHC).

Erythrocyte Membrane
|
D004910 |
[The semi-permeable outer structure of a red blood cell. It is known as a red cell 'ghost' after HEMOLYSIS.
] |
|
Erythrocyte Transfusion
|
D017707 |
[The transfer of erythrocytes from a donor to a recipient or reinfusion to the donor.
] |
|
Erythrocyte Volume
|
D004911 |
[Volume of circulating ERYTHROCYTES . It is usually measured by RADIOISOTOPE DILUTION TECHNIQUE.
] |
|
Erythrocytes
|
D004912 |
[Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.
] |
|
Erythrocytes, Abnormal
|
D004913 |
[Oxygen-carrying RED BLOOD CELLS in mammalian blood that are abnormal in structure or function.
] |
|
Erythroid Cells
|
D041905 |
[The series of cells in the red blood cell lineage at various stages of differentiation.
] |
|
Erythroid Precursor Cells
|
D015672 |
[The cells in the erythroid series derived from MYELOID PROGENITOR CELLS or from the bi-potential MEGAKARYOCYTE-ERYTHROID PROGENITOR CELLS which eventually give rise to mature RED BLOOD CELLS. The erythroid progenitor cells develop in two phases: erythroid burst-forming units (BFU-E) followed by erythroid colony-forming units (CFU-E); BFU-E differentiate into CFU-E on stimulation by ERYTHROPOIETIN, and then further differentiate into ERYTHROBLASTS when stimulated by other factors.

Erythroid-Specific DNA-Binding Factors
|
D050981 |
[A group of transcription factors that were originally described as being specific to ERYTHROID CELLS.
] |
|
Erythrokeratodermia Variabilis
|
D056266 |
[An autosomal dominant skin disease characterized by transient and variable noninflammatory ERYTHEMA and hyperkeratosis. It has been associated with mutations in the genes that code for CONNEXINS. Erythrokeratodermia variabilis inherited in an autosomal recessive fashion has also been reported. Affected individuals often develop PALMOPLANTAR KERATODERMA.

|
Erythromelalgia
|
D004916 |
[A peripheral arterial disease that is characterized by the triad of ERYTHEMA, burning PAIN, and increased SKIN TEMPERATURE of the extremities (or red, painful extremities). Erythromelalgia may be classified as primary or idiopathic, familial or non-familial. Secondary erythromelalgia is associated with other diseases, the most common being MYELOPROLIFERATIVE DISORDERS.
