introduction: acute promyelocytic leukemia treatment revolutionized by new tretamnets. currently number of patinets who undergoe hematopoietic stem cell transplantation decrased so experience with this modality is limited. here we report our experience with stem cell transplantation in acute promyelocytic leukemia patients. design and setting: retrospective, single center methods: between year ...

The Yorktown APL Translator (YAT) permits functions written in APL to be compiled using an existing compiler for part of the process. It also creates tables that allow the APL2 Release 2 interpreter to call the compiled code. The code can also be called from a Fortran main routine. This paper outlines the history of APL compilation, the motivation for producing YAT, the design choices that were...

Background: Antiphospholipid antibodies (aPL) are a heterogeneous family of anti-bodies associated with thrombosis and other complications. Objective: To study the prevalence of aPL in patients with thrombosis at Aleppo University Hospitals, Syria. Methods: One hundred and fifty-seven patients with venous and arterial thrombosis and 63 healthy controls were studied. Anticardiolipin antibodies (...

introduction: arsenic trioxide is effective and approved for treatment of relapsed or refractory apl cases to atra but its effects in new cases of apl is not clear and needs long term follow up to dis close the role of this drug in treatment of apl in combination with chemotherapy/atra or alone. material and methods: we studied 111cases of apl (94 new case and 17 relapsed) diagnosed by mor phol...

The Aplysia nervous system contains two phorbol ester-activated protein kinase C isoforms, the Ca(2+)-activated Apl I and the Ca(2+)-independent Apl II. Short-term applications of the facilitatory transmitter serotonin (5-HT) activates Apl I, but not Apl II. In contrast, Apl II, but not Apl I, can form an autonomous kinase. To investigate the biochemical characteristics of the Aplysia kinases t...

background: acute promyelocytic leukemia (apl) is a unique subtype of acute leukemia. apl is a curable disease; however, drug resistance, early mortality, disease relapse and treatment-related complications remain challenges in apl patient management. one issue underlying these challenges is that the molecular mechanisms of the disease are not sufficiently understood. materials and methods: in ...

The coagulopathy of acute promyelocytic leukemia (APL) is mainly related to procoagulant substances and fibrinolytic activators of APL blasts, but the fate of these leukemic cells is unknown. The aim of this study was to investigate the removal of APL blasts by macrophages and endothelial cells in vitro and consequent procoagulant and fibrinolytic activity of APL cells. We found that human umbi...

No unified immunophenotypic profiles and corresponding analytic strategies have been established for the rapid diagnosis of acute promyelocytic leukemia (APL) using flow cytometry (FCM). Here we describe a characteristic immunophenotypic panel that can rapidly and accurately distinguish APL from other types of adult acute myeloid leukemia (AML) using only FCM. By comparing APL cells and non-APL...
