Louis Henri Vaquez: Louis Henri Vaquez (27 August 1860 – 1936) was a French internist born in Paris. He is known for his work in the field of hematology and his research of heart disease.PolycythemiaJanus kinase 2: Janus kinase 2 (commonly called JAK2) is a non-receptor tyrosine kinase. It is a member of the Janus kinase family and has been implicated in signaling by members of the type II cytokine receptor family (e.MyelofibrosisMyelodysplastic–myeloproliferative diseases: Myelodysplastic–myeloproliferative diseases are a category of hematological malignancies disorders created by the World Health Organization which have characteristics of both myelodysplastic and myeloproliferative conditions.PipobromanThrombocytosisAloe buettneriContinuous erythropoietin receptor activator: Continuous erythropoietin receptor activator (CERA) is the generic term for drugs in a new class of third-generation erythropoiesis-stimulating agents (ESAs). In the media, these agents are commonly referred to as 'EPO', short for erythropoietin.American Society of Phlebotomy Technicians: American Society of Phlebotomy Technicians (ASPT) is the second oldest certifying agency for Phlebotomy. The ASPT was founded in 1983.Congenital amegakaryocytic thrombocytopeniaErythropoiesisGranulocyte: framed|Eosinophilic granulocyteThrombusHydroxyurea dermopathyBloodletting (Boxer album): Bloodletting[ Bloodletting] at Allmusic was an album by the rock band Boxer, released on the Virgin record label in 1979. Their third album in order of release, it had in fact been recorded in 1976 after their debut Below the Belt.Hematocrit: The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood. It is normally 45% for men and 40% for women.Missense mutation: In genetics, a missense mutation (a type of nonsynonymous substitution) is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid. Another type of nonsynonymous substitution is a nonsense mutation in which a codon is changed to a premature stop codon that results in truncation of the resulting protein.Blueberry muffin baby: Blueberry muffin baby is the characteristic distributed purpura occurring as a result of extramedullary hematopoiesis found in infants. The purpura are often generalized, but occur more often on the trunk, head, and neck.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Repulsive guidance molecule: Repulsive Guidance Molecules (RGMs) are members of a three gene family (in vertebrates) composed of RGMa, RGMb, and RGMc (also called hemojuvelin).Budd–Chiari syndromeIsoantigen: An isoantigen is a type of antigen which is present only in subsets of a species.Thrombopoietin: Thrombopoietin (THPO) also known as megakaryocyte growth and development factor (MGDF) is a protein that in humans is encoded by the THPO gene.Bone marrow suppression: Bone marrow suppression or myelotoxicity (adjective myelotoxic) or myelosuppression is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine.Myeloid: The term myeloid (myelogenous) is an adjective that can refer to a progenitor cell for granulocytes, monocytes, erythrocytes, or platelets. Myeloid can be distinguished from the lymphoid progenitor cells that give rise to B cells and T cells.
