Mitochondria (mt) play an important role in both apoptosis and haem synthesis. The present study was conducted to determine DNA mutations in mitochondrial encoded cytochrome c-oxidase I and II genes. Bone marrow (BM) biopsy and aspirate, peripheral blood (PB) and buccal smear samples were collected from 20 myelodysplastic syndrome (MDS) patients and 10(More)
The high relapse rate of hematologic malignancy treated with autologous bone marrow transplantation (ABMT) may reflect the absence of a graft-versus-leukemia (GVL) effect usually associated with graft-versus-host disease (GVHD). The purpose of this study was to determine whether administration of interleukin-2 (IL-2) early after ABMT might induce or(More)
Neurons are continually added at a low rate to the granule cell layer of the dentate gyrus during adulthood in rats. The functional significance of this unusual feature is not completely understood, although recent studies suggest continued granule cell neurogenesis is essential for normal learning and memory. We report here that, in the adult rat,(More)
Labeling index (LI), apoptosis, levels of 2 pro-apoptotic cytokines tumor necrosis factor-alpha (TNF-alpha) and transforming growth factor-beta(TGF-beta), and the number of monocyte/macrophage cells that are the likely source of the cytokines were simultaneously measured in plastic-embedded bone marrow (BM) biopsy sections of 145 patients with(More)
Rationale: Clinical studies have shown that the opioid antagonist naltrexone is effective in the treatment of alcoholism. However, the mechanism by which it produces this effect is not understood. Objective: This study was designed to investigate the effect of acute naltrexone on consumption of ethanol in healthy, non-problem social drinkers. Methods:(More)
IL-2 with or without autologous lymphokine-activated killer (LAK) cells, administered early after ABMT for AML may eradicate residual disease and reduce relapses. This paper reports 14 patients who received IL-2 or IL-2 plus LAK cells after ABMT for AML in first relapse or at a later stage, in two separate trials. Patients with AML in first relapse (n = 9),(More)
Thirty patients with myelodysplastic syndromes (MDS) were treated with thalidomide at 100 mg/d p.o., increased as tolerated to 400 mg/d for 12 weeks. Levels of apoptosis, macrophage number, microvessel density (MVD), tumour necrosis factor alpha (TNF-alpha), transforming growth factor beta (TGF-beta), interleukin 6 (IL-6), vascular endothelial growth factor(More)
We tested whether prevention of hibernation in ground squirrels by midwinter exposure to high ambient temperatures influenced timing of the spring phase of reproductive maturation and the phase and period of subsequent circannual rhythms of reproduction and body mass. Exposing hibernating adult male Spermophilus lateralis to 30 degrees C for 6 weeks(More)
Early relapse remains a major challenge after autologous bone marrow transplant for malignant lymphoma (ML). It is postulated that consolidative immunotherapy with interleukin 2 (IL-2) with or without lymphokine-activated killer (LAK) cells administered after autologous bone marrow (ABMT) or peripheral blood stem cell transplantation (PBSCT) for ML might(More)
