The peripheral blood lymphocyte to monocyte ratio (LMR) at diagnosis has been used to predict survival in diffuse large B-cell lymphoma (DLBCL) patients, but its prognostic significance with respect to different cell-of-origin (COO) subtypes remains unknown. We retrospectively analyzed 168 de novo DLBCL patients in this study and found that a low LMR (≤2.6)(More)
Expression of CD44 splice isoforms has been previously reported to correlate with inferior outcomes in DLBCL patients treated with CHOP therapy. However, it is unclear whether this observation remains valid in the R-CHOP era. In this study, we correlated CD44H and CD44v6 status with survival outcomes among DLBCL patients with an emphasis on the comparison(More)
BACKGROUND Nilotinib, an oral second-generation Bcr-Abi tyrosine kinase inhibitor, is approved in the United States and European Union for the treatment of Philadelphia chromosome-positive (Ph+), chronic-phase (CP) or accelerated-phase (AP) chronic myeloid leukemia (CML) resistant to or intolerant of prior therapy, including imatinib. Information on the(More)
OBJECTIVE To explore the association between chimerism, minimal residual disease (MRD) and relapse after sex-mismatched allogeneic hematopoietic stem cell transplantation (allo-HSCT) for leukemia. METHODS Fifty-seven patients with leukemia received allogeneic hematopoietic stem cell grafts from HLA-matched or partially matched, but sex-mismatched donors.(More)
We performed a prospective study to evaluate the efficacy and safety of secondary antifungal prophylaxis (SAP) for patients with a history of invasive pulmonary aspergillosis (IPA) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). In this study, the prophylactic agents used were chosen based on treatment response to initial antifungal(More)
Heterogeneous III-V/Si integration with a compact optical vertical interconnect access is fabricated and the light coupling efficiency between the III-V/Si waveguide and the silicon nanophotonic waveguide is characterized. The III-V semiconductor material is directly bonded to the silicon-on-insulator (SOI) substrate and etched to form the III-V/Si(More)
Ridge waveguide 1.3 mum GaInNAs lasers were fabricated from high quality double quantum well material grown by molecular beam epitaxy. Short cavity (250 mum) lasers have low threshold currents and small temperature dependencies of threshold current and slope efficiency, with a characteristic temperature of the threshold current as high as 200 K. The(More)
The prognostic value of CD30 expression in diffuse large B-cell lymphoma (DLBCL)remains controversial. Herein, we performed this retrospective study to investigate the clinical and prognostic significance of CD30 expression in patients with DLBCL.Among all the 146 patients, the expression of CD30 was observed in 23 cases (15.7%).The DLBCL patients with CD30(More)
The absolute lymphocyte count (ALC) has been reported to predict relapse in diffuse large B-cell lymphoma (DLBCL). We performed the present study to determine whether the ALC could identify preclinical relapse during routine follow-up. Among all 148 patients analyzed, 39 patients exhibited relapse. Patients without relapse had a higher ALC compared with(More)
We have demonstrated a heterogeneously integrated III-V-on-Silicon laser based on an ultra-large-angle super-compact grating (SCG). The SCG enables single-wavelength operation due to its high-spectral-resolution aberration-free design, enabling wavelength division multiplexing (WDM) applications in Electronic-Photonic Integrated Circuits (EPICs). The SCG(More)
