introduction: the myeloproliferative neoplasms (mpns) are a heterogeneous group of diseases characterized by excessive production of blood cells by  hematopoietic precursors. typically, they include polycythemia vera (pv), essential thrombocythemia (et), idiopathic myelofibrosis(imf), and chronic myeloid leukemia (cml). philadelphia chromosome is the final diagnostic test for cml. recently, jak...

Introduction. The Myeloproliferative Neoplasms are a heterogeneous group of clonal hematopoietic stem cell disorders characterized by increased proliferation the myeloid lineages in bone marrow. A particular clinical challenge is presented certain situations patients with myeloproliferative Neoplasms, which we do not encounter daily. For this reason, paper, will emphasize approach to overcoming...

mirs are 17-25 nucleotide non-coding rnas. these rnas target approximately 80% of protein coding mrnas. mirs control gene expression and altered expression of them affects the development of cancer. mirs can function as tumor suppressor via down-regulation of proto-oncogenes and may function as oncogenes by suppressing tumor suppressors. myeloproliferative neoplasias (formerly known as chronic ...

Budd-Chiari syndrome (BCS) is an uncommon condition induced by thrombotic or non-thrombotic obstruction of hepatic venous outflow. BCS most often occurs in patients with underlying thrombotic diathesis, including such myeloproliferative disorders (MPDs) as polycythemia vera and paroxysmal nocturnal hemoglobinuria, and pregnancy, oral contraceptives, tumors, chronic inflammatory diseases, clotti...
