Comparison of off-resonance saturation with single and dual frequency irradiation indicates a contribution of inhomogeneously broadened lines to magnetization transfer in tissues. This inhomogeneous magnetization transfer (ihMT) phenomenon can be exploited to produce images that highlight tissues containing myelin, in vivo. Here, a model for ihMT is(More)
Cardiac complications related to bone marrow grafting were investigated in a group of 63 patients undergoing bone marrow transplantation (57 autologous, 6 allogeneic) in the transplant unit of Hôpital Saint-Antoine (Paris, France) between February 1977 and October 1983. The pregraft regimen was cyclophosphamide, 6-thioguanine, cytosine arabinoside, and CCNU(More)
In some acute leukemias, blast cells may lack morphologic and cytochemical characteristics indicating their original cell line. Whether these cells are in fact undifferentiated or derived from early precursors of lymphocytes or of other cell lines remains open to question. Leukemias with megakaryoblast (MKB) predominance have been considered rare. In these(More)
We compared the presence of serologic markers of hepatitis B virus (HBV) infection with the presence of the viral DNA in the livers of patients with alcoholic liver disease with or without hepatocellular carcinoma. Among 51 patients with various kinds of alcoholic liver disease but without hepatocellular cancer, 19 had one or more serologic markers of HBV,(More)
The diagnostic value in polycythemia of the presence of endogenous erythroid colonies derived from bone marrow cells (EECs) was assessed in a prospective study on 108 patients referred for polycythemia (Hb greater than g/dL in men, greater than 16 g/dL in women) with normal plasma volume by comparison with the standard criteria, the bone marrow grade, and(More)
The aim of the study was to investigate the atherosclerosis risk factors related to hyperlipidemia in renal transplanted children. Plasma cholesterol, triglycerides, apolipoproteins (Apo) AI, AII and B, and the major lipoprotein classes separated by gradient ultracentrifugation were compared in 30 renal transplanted patients and 14 healthy children.(More)
