... JAK2 have increasingly been identified in patients with JAK2 V617F - negative MPNs. Here, we present a case of a patient diagnosed with JAK2 V617F-negative polycythemia vera (PV) that transformed to the MPN-blast phase. Cytogenetic and FISH analysis revealed a novel translocation of t(1;9)(p36;p24.1...

...Jan Jacques Michiels; Zwi Berneman; Wilfried Schroyens; Hendrik De Raeve The Polycythemia Vera Study Group (PVSG) and WHO classifications distinguished the Philadelphia (Ph 1 ) chromosome-positive chronic myeloid leukemia from the Ph 1 -negative myeloproliferative neoplasms (MPN) essential...

... in the P2Y 12 pathway, no previous studies have specifically evaluated P2Y 12 function in MPN or the relationship between P2Y 12 function and the JAK2 V617F mutation. Methods: Forty-one MPN patients were enrolled, including 24 with essential thrombocythemia (ET), 16 with polycythemia vera (PV) and 1...

Balduini Red cell membrane glycopeptides of subjects suffering from different hematological disorders (PNH, hemolytic anemias, dyserythropoietic anemias and polycythemia vera) have been characterized. In most cases, except in polycythemia vera, a decrease...

...John D. Lutton; Richard D. Levere Peripheral blood mononuclear cells from patients with polycythemia vera or myelofibrosis with myeloid metaplasia were studied for their erythroid colony growth characteristics in plasma clot cultures. In both diseases, erythroid colonies formed early in culture...

...M. Djaldetti; A. Cohen; J. Hart A patient with polycythemia vera showed marked elliptocytosis in the peripheral blood, 2 years after the diagnosis was established. 4 years later on, the patient developed myelofibrosis. The significance of elliptocytosis, which appears during the course...

...Nelly Avissar; Yehuda Farkash; Mali Shaklai Fifteen cytoplasmic erythrocyte enzyme activities were determined in patients with polycythemia vera (PV), iron deficiency anemia (IDA), and a group of healthy volunteers. Among the PV patients, the erythrocyte enzyme activities were compared between 2...

...Raj R. Mittal; Arnold I. Meisler An 87-year-old male patient known to have polycythemia vera presented at the hospital as an acute abdominal emergency. Ultrasonography of the abdomen revealed a homogeneous echogenic mass measuring 22 × 15 × 8 cm in fascial planes anterior to the peritoneum, which...
