Iron overload, caused by hereditary hemochromatosis or repeated blood transfusions in some diseases, such as beta thalassemia, bone marrow failure and myelodysplastic syndrome, can significantly induce injured bone marrow (BM) function as well as parenchyma organ dysfunctions. However, the effect of iron overload and its mechanism remain elusive. In this(More)
OBJECTIVES Transfusional iron overload is of major concern in hematological disease. Iron-overload-related dyserythropoiesis and reactive oxygen species (ROS)-related damage to hematopoietic stem cell (HSC) function are major setbacks in treatment for such disorders. We therefore aim to investigate the effect of iron overload on hematopoiesis in the(More)
OBJECTIVE Using a mouse model, Iron Overload (IO) induced bone marrow microenvironment injury was investigated, focusing on the involvement of reactive oxygen species (ROS). METHODS Mice were intraperitoneally injected with iron dextran (12.5, 25, or 50 mg) every three days for two, four, and six week durations. Deferasirox(DFX)125 mg/ml and(More)
OBJECTIVE To establish a model of hematopoietic stem and progenitor cells with iron overload derived from umbilical cord blood (UCB) cells and explore the effects of reactive oxygen species (ROS) on the hematopoiesis of hematopoietic stem and progenitor cells with iron overload. METHODS The model was established by adding different concentrations (50,(More)
OBJECTIVE To explore effect of iron overload on the proliferation and apoptosis of mesenchymal stem cell(MSCs) and the possible mechanism. METHODS Iron overload model of MSCs was established by adding ferric ammonium citrae (FAC) into the culture medium at different concentrations (100, 200, 400 Μmol/L) and incubated for different lengths of time (12, 24,(More)
We describe a method for characterizing certain connected components of the moduli space M(a; b) of torsion-free sheaves on a elliptic surface X with a section which are stable with respect to a polarization of type aH + bb, H being the section and the elliptic bre (b 0) and whose relative degree is zero. We construct all sheaves in these components as(More)
OBJECTIVE To establish a mouse model of iron overload by intraperitoneal injection of iron dextran and investigate the impact of iron overload on bone marrow hematopoiesis. METHODS A total of 40 C57BL/6 mice were divided into control group, low-dose iron group (12.5 mg/ml), middle-dose iron group (25 mg/ml), and high-dose iron group (50 mg/ml). The(More)
The iron-overload mouse model used in this study was previously reported by the authors in references 1 and 2, which are not cited in the Article. The data supporting the mouse model is presented in Figure 1 of the Article. The data presented in in Figure 1b appear in reference 1 as Figure 1b; and the data presented in Figure 1c appear in reference 1 as(More)
Resumen Durante muchos años la mejora de los procesos de desarrollo y mantenimiento de software se ha estudiado desde un punto de vista de ingeniería, con la premisa de que un mejor proceso de desarrollo permite la construcción de mejores productos. En este contexto son bien conocidos modelos de madurez como CMM, CMMI, ISO/IEC 15504 o ISO 9001:2000. Más(More)
This study was aimed to detect the expression of leukemia stem/progenitor cell (LSPC) related genes (ABCB1, BMI-1, HOXB4) in the patients with acute leukemia, and to explore its clinical significance in acute leukemia. Bone marrow samples were collected from de novo acute leukemia patients (41 cases), patients with complete remission (CR, 16 cases) and the(More)
