Improving the Cyclic Reversibility of Layered Li-Rich Cathodes by Combining Oxygen Vacancies and Surface Fluorination.

Layered-type Li-rich cathode materials have attracted significant attention for next-generation Li-ion batteries, but the advantage of their high capacity is eclipsed by their poor reversibility upon cycling. Irreversible oxygen redox activity and surface degradation have been deemed as the root cause and direct cause for their poor performance, respectively. We attempted to suppress surface degradation by inserting fluoride ions up to some depth on the surface.

Unique Li deposition behavior in LiPS solid electrolyte observed X-ray computed tomography.

The problem of lithium dendrites must be addressed for practical lithium metal all-solid-state batteries. Herein, three-dimensional morphological changes within LiPS electrolyte away from the anode were observed using X-ray computed tomography. We revealed that the electronic conduction of decomposition and the electrolyte/void interface cause the lithium deposition within the LiPS.

Challenges for fluoride superionic conductors: fundamentals, design, and applications.

Electronics, which harnesses the properties of electrons, has made remarkable progress since its inception and is a cornerstone of modern society. Ionics, which exploits the properties of ions, has also had a profound impact, as demonstrated by the award of the Nobel Prize in Chemistry in 2019 for achievements related to lithium-ion batteries (LIBs). Ionic conduction in solids is the flow of carrier ions through a solid owing to an electrical or chemical bias.

Clinical significance of oxidative stress for untreated patients with diffuse large B-cell lymphoma.

Oxidative stress serves an important role in carcinogenesis. The present study investigated the clinical significance of oxidative stress as a prognostic factor for diffuse large B-cell lymphoma (DLBCL). The participants comprised 55 consecutive patients with DLBCL.

Spin polarization in the phase diagram of a Li-Fe-S system.

Divalent and trivalent states of Fe ions are known to be stable in inorganic compounds. We focus a novel LiFeS cathode, in which the Li content (x) changes from 2 to 10 by an electrochemical technique. As x increases from 2, a Pauli paramagnetic conductive LiFeS phase changes into a superparamagnetic insulating LiFeS phase.

R-THP-COP versus R-CHOP in patients younger than 70 years with untreated diffuse large B cell lymphoma: A randomized, open-label, noninferiority phase 3 trial.

Pirarubicin (tetrahydropyranyl adriamycin [THP]) is an anthracyclin with less cardiotoxicity than doxorubicin (DOX). We previously reported the efficacy and safety of R-THP-COP consisting of rituximab (R), THP, cyclophosphamide (CPA), vincristine (VCR), and prednisolone (PSL) for diffuse large B cell lymphoma (DLBCL) in phase 2 studies. Here, we prospectively compared the efficacy and safety of the R-THP-COP and standard R-CHOP regimen (consisting of R, CPA, DOX, VCR, and PSL) in a noninferiority phase 3 trial.

Association between increased serum GP88 (progranulin) concentrations and prognosis in patients with malignant lymphomas.

Background: GP88 (progranulin; PGRN) is a secreted 88kDa glycosylated protein, with important functions, including inflammation and tumorigenesis. We assessed the significance of GP88 expression in survival outcomes of patients with malignant lymphoma (ML).

Methods: Serum samples from 254 previously untreated ML patients were examined to measure GP88 concentrations using a sandwich human GP88 ELISA kit.

Serum concentrations of l-kynurenine predict clinical outcomes of patients with peripheral T-cell lymphoma, not otherwise specified.

Indoleamine 2,3-dioxygenase exerts intense immunomodulatory effects due to enzymatic activities that catalyze the breakdown of the essential amino acid l-tryptophan. The activity of indoleamine 2,3-dioxygenase can be estimated by measuring serum l-kynurenine concentrations. Here, we aimed to determine the role of l-kynurenine as a prognostic factor for peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) in a retrospective analysis of data derived from 31 consecutive patients between June 2000 and March 2013 who were histologically diagnosed with PTCL-NOS according to the World Health Organization classification and treated with 6-8 cycles of cyclophosphamide, doxorubicin or pirarubicin, vincristine, and prednisolone.

A salvage chemotherapy of R-P-IMVP16/CBDCA consisting of rituximab, methylprednisolone, ifosfamide, methotrexate, etoposide, and carboplatin for patients with diffuse large B cell lymphoma who had previously received R-CHOP therapy as first-line chemotherapy.

We have reported the efficacy of the salvage chemotherapy P-IMVP16/CBDCA for patients with diffuse large B cell lymphoma (DLBCL) who had previously received CHOP before the availability of rituximab (R). Here, we confirmed the efficacy of R combined with P-IMVP16/CBDCA as a salvage chemotherapy for patients with DLBCL, who had previously received R-CHOP. We retrospectively analysed 59 patients with relapse or refractory DLBCL (38 male patients and 21 female patients) presenting between June 2004 and June 2013.

CHOP or THP-COP regimens in the treatment of newly diagnosed peripheral T-cell lymphoma, not otherwise specified: a comparison of doxorubicin and pirarubicin.

The CHOP regimen consisting of cyclophosphamide, doxorubicin (DOX), vincristine and prednisolone has been the most used regimen for peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS). Pirarubicin [tetrahydropyranyladriamycin (THP)], a derivative of DOX, is an anthracycline with reportedly less cardiotoxicity than DOX. Here, we confirmed the efficacy of THP-COP using THP instead of DOX in the treatment of PTCL-NOS.

Cytokeratin-positive fibroblastic reticular cell tumor with follicular dendritic cell features: a case report and review of the literature.

Fibroblastic reticular cell (FRC) neoplasms, which are one of the histiocyte tumor types, are very rare. Here we report a cytokeratin (CK)-positive FRC neoplasm having features of follicular dendritic cells in a 54-year-old woman with right axillary lymph node swelling. The resected lymph node showed multiple nodular aggregations simulating and replacing normal follicles.

Pathogenesis of Morquio A syndrome: an autopsied case reveals systemic storage disorder.

Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is a lysosomal storage disorder caused by deficiency of N-acetylgalactosamine-6-sulfate sulfatase, which results in systemic accumulation of glycosaminoglycans (GAGs), keratan sulfate and chondroitin-6-sulfate. Accumulation of these GAGs causes characteristic features as disproportionate dwarfism associated with skeletal deformities, genu valgum, pigeon chest, joint laxity, and kyphoscoliosis. However, the pathological mechanism of systemic skeletal dysplasia and involvement of other tissues remain unanswered in the paucity of availability of an autopsied case and successive systemic analyses of multiple tissues.

Serum level of soluble tumor necrosis factor receptor 2 is associated with the outcome of patients with diffuse large B-cell lymphoma treated with the R-CHOP regimen.

Background: Serum soluble tumor necrosis factor receptor 2 (sTNFR2) concentration predicted the clinical outcome of patients with aggressive non-Hodgkin's lymphoma including diffuse large B-cell lymphoma (DLBCL) treated with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) in our previous study. However, after rituximab (R) was introduced in clinical practice, R-CHOP replaced CHOP as the standard therapy for DLBCL.

Patients And Methods: In this study, we re-evaluated the prognostic significance of serum sTNFR2 in 154 patients with DLBCL treated with R-CHOP.

Diagnosis of the jejunoileal lymphoma by double-balloon endoscopy.

Aim: To investigate the feasibility of double-balloon endoscopy (DBE) to detect jejunoileal lymphoma, compared with fluorodeoxyglucose positron emission tomography (FDG-PET).

Methods: Between March 2004 and January 2011, we histologically confirmed involvement of malignant lymphoma of the jejunoileum in 31 patients by DBE and biopsy. In 20 patients of them, we performed with FDG-PET.

Clinical significance of jejunoileal involvement of non-Hodgkin's lymphoma detected by double-balloon enteroscopy.

Jejunoileal involvement of non-Hodgkin's lymphoma (NHL) is an important diagnostic factor in determining optimal treatment strategies. Here, we used double-balloon enteroscopy (DBE) to detect jejunoileal involvement of NHL and studied its clinical significance in a series of patients with NHL. Adults aged between 18 and 85 years with infiltration of the stomach, duodenum, or colon confirmed by gastrointestinal endoscopy or colonoscopy, suspected jejunoileal involvement determined by CT or FDG-PET, or any other gastrointestinal symptoms, were eligible for inclusion in the study.

Lactobacillus acidophilus strain L-92 induces CD4(+)CD25(+)Foxp3(+) regulatory T cells and suppresses allergic contact dermatitis.

The anti-allergic mechanism of heat-killed Lactobacillus acidophilus strain L-92 has not been fully investigated. Recent studies have reported that CD4(+)CD25(+)Foxp3(+) (forkhead box P3) T regulatory (Treg) cells play important roles in controlling allergic diseases. Hence, we examined the effect of orally administered L-92 on CD4(+)CD25(+)Foxp3(+) cell populations.

Serum soluble CD27 level is associated with outcome in patients with diffuse large B-cell lymphoma treated with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone.

Since the introduction of rituximab (R), the prognosis for diffuse large B-cell lymphoma (DLBCL) has markedly improved. We evaluated the prognostic significance of serum soluble CD27 (sCD27) in 143 patients with DLBCL treated with cyclophosphamide, doxorubicin, vincristine and prednisolone plus rituximab (R-CHOP). Five-year overall survival rates for patients with sCD27≥213 U/mL or <213 U/mL were 38.

Serum soluble interleukin-2 receptor (sIL-2R) level is associated with the outcome of patients with diffuse large B cell lymphoma treated with R-CHOP regimens.

Serum concentration of soluble interleukin-2 receptor (sIL-2R) predicts the clinical outcome of patients with aggressive non-Hodgkin's lymphoma treated with the cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) regimen without rituximab. In the present study, we aim to re-assess the prognostic significance of serum sIL-2R for diffuse large B cell lymphoma (DLBCL) patients treated with CHOP plus rituximab and to assess sIL-2R with subtype of DLBCL, such as GCB type and non-GCB type. Two hundred and thirty-three patients with DLBCL were enrolled between December 2002 and March 2008.

Endoscopic ultrasound-guided fine needle aspiration biopsy for diagnosis of lymphoproliferative disorders: feasibility of immunohistological, flow cytometric, and cytogenetic assessments.

Objectives: In addition to morphology, immunophenotype and genetic abnormalities should be assessed during diagnosis and subclassification of lymphoproliferative disorders. The objective of this study was to evaluate the yield of endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) using a standard 19-gauge needle for diagnosis and subclassification of lymphoma, assessing the feasibility of immunohistological, flow cytometric, and cytogenetic assessments.

Methods: Two hundred forty patients with suspected lymphoma were referred for EUS-FNAB to our quaternary EUS center between June 2005 and December 2010.

Diffuse skeletal muscles uptake of [18F] fluorodeoxyglucose on positron emission tomography in primary muscle peripheral T-cell lymphoma.

A 40-year-old man presented with weakness of neck extensor muscles. Cervical magnetic resonance imaging showed high-intensity areas in muscles of the left lateral cervical region on T2-weighted images. Fluorodeoxyglucose-positron emission tomography scan demonstrated striking fluorodeoxyglucose uptake by multiple skeletal muscles of the neck, chest, and abdominal region.

A phase II study of rituximab combined with pirarubicin-cyclophosphamide, vincristine and prednisolone regimen as first-line therapy for patients with indolent B-cell lymphoma.

The anthracycline drug pirarubicin (tetrahydropyranyl-adriamycin [THP]) apparently has been reported to show fewer cardiotoxic effects than doxorubicin. We have previously described the effectiveness of the R-THP-COP regimen comprising rituximab, cyclophosphamide, pirarubicin, vincristine and prednisolone in patients with diffuse large B-cell lymphoma. We conducted a phase II study to determine the effectiveness of a regimen incorporating rituximab (R-THP-COP) for patients with previously untreated advanced-stage indolent CD20-positive B-cell lymphoma according to the Working Formulation and World Health Organization classification.

Serum interleukin-18 level is associated with the outcome of patients with diffuse large B-cell lymphoma treated with CHOP or R-CHOP regimens.

Background: We have previously reported that serum interleukin-18 (IL-18) concentration predicted the clinical outcome of patients with aggressive non-Hodgkin's lymphoma treated with cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP). When rituximab (R) was added to this regimen, the prognosis of diffuse large B-cell lymphoma (DLBCL) was markedly improved.

Patients And Methods: In this study, we re-evaluated the prognostic significance of serum IL-18 in 227 DLBCL patients.

Follicular variant of peripheral T-cell lymphoma mimicking follicular lymphoma: a case report with a review of the Literature.

Peripheral T-cell lymphoma (PTCL) with a follicular growth pattern is very rare. Herein, a case of follicular variant of PTCL in a 50-year-old man who complained of tonsillar and generalized lymph node swelling is reported. The resected tonsil revealed a vague nodular growth pattern of atypical cells, medium to large in size, with abundant pale cytoplasm.
