The XE-2100 is a new automated hematology analyzer developed by Sysmex Corporation. With consideration of medical analyzer requirements for the 21st century, this unit was developed to satisfy the following concepts and to cope with diversified laboratory needs. 1) Electronic network communication 2) Presentation of high level value-added information 3) Contribution to test cost control 4) Purs...

OBJECTIVES Implantation of cell separation and mesenchymal stem cell culture techniques from human umbilical cord blood with and without using the Ficoll-Paque gradient density method (d=1.077 g/ml). METHODS Ten samples of the umbilical cord blood obtained from full-term deliveries were submitted to two different procedures of mesenchymal stem cell culture: a) Method without the Ficoll-Paque ...

Cell infection with Trypanosoma cruzi, the agent of Chagas' disease, begins with the uptake of infective trypomastigotes within phagosomes and their release into the cytosol, where they transform into replicating amastigotes; the latter, in turn, differentiate into cytolytically released and infective trypomastigotes. We ask here if the T. cruzi infection program can develop in enucleated host ...

Cell suspensions of the transplantable Furth murine mast cell tumor were separated both by velocity sedimentation in an isokinetic gradient and by isopyknic sedimentation. Prior to separation, the suspension of tumor cells contained 60.3+/-13.1% (S.D.) malignant mast cells, 9.8+/-10.4% lymphocytes, 4.3+/-2.1% granulocytes, 1.7+/-1.9% macrophages, 0.6+/-0.4% unidentified cells, and 22.8+/-8.5% r...

On day 33 of gestation, foetal beagles were irradiated in utero (0.9 Gy of 60Co gamma-irradiation, 0.4 Gy/min). Foetal haematocytopoiesis was studied during the third trimester of gestation (days 42-55). Peripheral blood nucleated cell counts were 33 per cent lower than normal on day 44 and continued to be lower until day 49, when values became higher than normal. Splenic cellularities of irrad...

BACKGROUND: Umbilical cord blood (UCB) has successfully used for transplantation to treat hematologic malignancies and genetic diseases. Herein, we describe the experience generated in a single public UCB bank at Zhejiang Province in China. METHODS: Good manufacturing practice and standard operating procedures were used to address donor selection as well as UCB collection, processing, and cryo...

schistosomiasis is the second most common parasitic cause of death, after malaria. biomphalaria glabrata is a fresh water snail with medical importance since it is the intermediate host of schistosoma mansoni, an agent of schistosomiasis. the internal defense system of b. glabrata snails is mostly represented by circulating elements of the hemolymph, hemocytes, which are important factors in fi...
