The combination of melphalan-prednisone-thalidomide (MPT) has been investigated in several clinical studies that differed significantly with regard to patient characteristics and treatment schedules. This prospective trial differs from previous melphalan-prednisone (MP) vs. MPT trials by treatment dosing, duration, routine anticoagulation, and permission(More)
BACKGROUND AIMS Mesenchymal stromal cells (MSC) exhibit non-specific hematopoietic cell and/or stromal cell markers (e.g. CD73, CD105 and CD166) that have been used to identify MSC by flow cytometry. Because a neural glial antigen, NG2 (a progenitor cell marker in the central nervous system), is expressed by several tissue cells originating in the(More)
Red cell exchange transfusion is the recommended therapy for patients with sickle cell disease who have complicated vaso-occlusive episodes. However, the role of the therapeutic plasma exchange in the management of the potentially life-threatening complications in patients with sickle cell disease is not well known. To determine whether plasma exchange had(More)
Increased thrombocyte activation leads to a higher likelihood of coagulation in sickle-cell disease. On the other hand, chronic inflammation and endothelial cell activation promote vaso-occlusion. The effect of circulating microparticles derived from erythrocytes, monocytes, thrombocytes, and endothelial cells on the vaso-occlusive process is unclear. This(More)
Propranolol, a non-selective β-adrenergic receptor blocker, has been used for the treatment of the patients with hypertension for more than 50 years. There are several in vitro and in vivo evidences that β-adrenergic receptor antagonists inhibit proliferation and angiogenesis and also increase apoptosis in breast, skin, and colon cancers. The aim of this(More)
The role of cytogenetic findings in determining the diagnosis, therapy and prognosis of acute myeloid leukaemia (AML) has become more valuable by the day. In this study, the results of conventional and molecular cytogenetic analyses and clinical outcomes of 66 AML patients of different subgroups aged between 16 and 82 were evaluated. Chromosomal(More)
Rhino-orbital-cerebral mucormycosis is a rare but often fatal opportunistic necrotizing infection of the sinuses, orbit, and brain caused by saprophytic fungi. It usually develops in patients with diabetes or immune system deficiency. In this study, imaging features in 3 patients with rhino-orbital-cerebral mucormycosis who presented with various symptoms(More)
Refractory condition can occur in 10–30% of all cases of thrombotic thrombocytopenic purpura despite increased frequency of total plasma exchange. Rituximab can affect the clinical outcome of the refractory cases. However, little is known about usefulness of rituximab on central nervous system involvement mimicking acute ischemic stroke. We report the case(More)
In automated red cell exchange, about 60% of the patient's red blood cells are exchanged via apheresis for those of the donor. We report the outcome of 83 patients with sickle cell anemia (48 women and 35 men; age range, 17-49 years) who underwent a total of 196 apheresis procedures between December 2003 and October 2006 at our institution. We found that(More)
BACKGROUND Sickle cell disease (SCD) is associated with chronic hemolysis and painful episodes. Pregnancy accelerates sickle cell complications, including prepartum and postpartum vasoocclusive crisis, pulmonary complications, and preeclampsia or eclampsia. Fetal complications include preterm birth and its associated risks, intrauterine growth restriction,(More)
