The zebrafish (Danio rerio) is increasingly being used to study basic vertebrate biology and human disease with a rich array of in vivo genetic and molecular tools. However, the inability to readily modify the genome in a targeted fashion has been a bottleneck in the field. Here we show that improvements in artificial transcription activator-like effector(More)
BACKGROUND & AIMS De novo hepatitis B virus (HBV)-related hepatitis after chemotherapy results in high morbidity and mortality. We evaluate the clinical course of de novo HBV-related hepatitis after chemotherapy. METHODS Two hundred forty-four consecutive hepatitis B surface antigen (HBsAg)-negative lymphoma patients treated with chemotherapy were(More)
Natural killer/T-cell lymphoma is rare and aggressive, with poor outcome. Optimal treatment remains unclear. A novel regimen dexamethasone, methotrexate, ifosfamide, l-asparaginase, and etoposide (SMILE) showed promise in phase 1/2 studies with restrictive recruitment criteria. To define the general applicability of SMILE, 43 newly diagnosed and 44(More)
OBJECTIVE The objective of our study was to evaluate the diagnostic performance of conventional whole-body MRI without and with diffusion-weighted imaging (DWI) in the detection of known (18)F-FDG-avid lymphomas. The conventional whole-body MRI protocol consisted of a T2-weighted sequence and a T2-weighted spectral attenuated inversion recovery (SPAIR)(More)
BACKGROUND Polyoma BK virus (BKV) is associated with hemorrhagic cystitis during hematopoietic stem cell transplantation (HSCT). The objective of this study was to test whether standard-dose ciprofloxacin might suppress reactivation of BKV infection during HSCT. METHODS Sixty-eight patients received ciprofloxacin or a cephalosporin as antibiotic(More)
Internal tandem duplication (ITD) of the fms-related tyrosine kinase-3 (FLT3) gene occurs in 30% of acute myeloid leukemias (AMLs) and confers a poor prognosis. Thirteen relapsed or chemo-refractory FLT3-ITD(+) AML patients were treated with sorafenib (200-400 mg twice daily). Twelve patients showed clearance or near clearance of bone marrow myeloblasts(More)
Angiogenesis plays an important role in a wide range of physiological processes such as wound healing and fetal development. Many diseases are associated with imbalances in regulation of angiogenesis, in which it is either excessive or there is insufficient blood vessel formation. Angelica sinensis (AS), commonly used in the prescriptions of Chinese(More)
The treatment results of indolent lymphoid malignancies in Chinese are poorly reported. The efficacy of FND (fludarabine 25 mg/m2/d, x3; mitoxantrone 10 mg/m2/d, x1; dexamethasone 20 mg/d, x5; monthly cycles, x6) in 95 Chinese patients with indolent B-cell malignancies (at diagnosis: 55, relapse/refractory disease: 40) and nine Chinese patients with T-cell(More)
To characterize T-cell large granular leukemia in Asia, 22 Chinese patients from a single institute were reported, together with an analysis of 88 Asian and 272 Western patients identified from the literature. In our cohort, anemia due to pure red cell aplasia (PRCA) occurred in 15/22 (68%) of cases, being the most common indication for treatment.(More)
BACKGROUND Graft-versus-host disease (GVHD) of the liver after allogeneic hematopoietic stem cell transplantation classically presents with increased bilirubin and alkaline phosphatase (ALP) levels. A hepatitic variant was recently recognized, with more than a 10-fold increase in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels.(More)
