The purpose of this study was to assess the efficacy of high-dose chemotherapy (HDC) with autologous stem cell transplant in stage IV breast cancer patients with minimal metastases. Eligible patients had (a) disease that could be resected en bloc and/or irradiated with curative intent using a single field and could, thus, be rendered as having no evidence of disease (NED); and/or (b) <5% bone m...

Primary central nervous system lymphoma (PCNSL) treatment includes 2 phases: induction and consolidation. Induction consists of high-dose methotrexate-based polychemotherapy for most patients, with regimen and dose variations according to patient characteristics and country. Several strategies have been proposed for the consolidation phase, with whole-brain irradiation (WBRT) the most common. H...

Heterogeneous distributed computing (HDC) systems, which exploit the aggregate power of a network of workstations and personal computers are an inexpensive alternative to the dedicated parallel supercomputing systems. As these systems are widely available in academic and industrial environments, it is becoming popular to use these computing resources to solve timeconsuming applications. The foc...

We examine the impact of negative clinical trial results on use of autologous hematopoietic cell transplantation (HDC/HCT) in breast cancer patients. Abandonment of occurred rapidly; one year after the results became public, volume was 20% of the 1998 peak. Teaching and research hospitals were slower to discontinue the procedure, and the pattern of decline suggests that hospitals passively aban...

To clarify the role of histamine-producing cells and its origin in atherosclerosis, we investigated histidine decarboxylase (HDC; histamine-producing enzyme) expression in murine arteries with vascular injuries after the animal had received transplanted bone marrow (BM) from green fluorescent protein (GFP)-transgenic mice. The neointima in the ligated carotid arteries contained BM-derived HDC+ ...

Secondary myelodysplastic syndromes (MDS) have been reported after autologous transplantation. It is not known whether the MDS results from the pretransplant conventional-dose chemotherapy or from the high-dose chemotherapy (HDC) used for the transplant procedure. We performed a multicenter, retrospective analysis of morphologically normal pretransplant marrow or stem cell specimens from 12 pat...

Histamine is involved in different physiological and pathological responses, such as immune response, gastric acid secretion or neurotransmission, as either angiogenesis or cancer. Histidine decarboxylase (HDC) catalyzes the formation of histamine from histidine. HDC has been suggested as a new marker for neuroendocrine differentiation, inflammatory pathologies and several leukemia and highly m...

Histamine plays an important role in the regulation of various immunological functions. To evaluate the role of histamine in contact hypersensitivity, contact dermatitis was induced with dinitrofluorobenzene (DNFB) in histidine decarboxylase knockout (HDC-/-) histamine-deficient and wild-type mice. The DNFB-induced increase of the ear thickness was significantly higher in HDC-/- mice than in wi...

Background—An increase in troponin I soon after high-dose chemotherapy (HDC) is a strong predictor of poor cardiological outcome in cancer patients. This finding has important clinical implications and provides a rationale for the development of prophylactic strategies for preventing cardiotoxicity. Angiotensin-converting enzyme inhibitors slow the progression of left ventricular dysfunction in...

We aimed to elucidate the role of the Ca-independent PKC isoenzyme PKCdelta in the regulation of spontaneous in vitro chondrogenesis occurring in a 6-day-long culturing period in chicken limb bud-derived high density cell cultures (HDC). PKCdelta expression and activity were detectable throughout the entire culturing period with a peak on days 2 and 3, when most of the chondroblasts differentia...
