Design: This retrospective study aimed to examine the temporal changes and their association with ADL independence levels based on the severity of PB and USN.

Setting: Recovery ward of Moriyama Neurological Center Hospital between March 2017 and October 2022.

Macrophage activation syndrome triggered by methotrexate-related lymphoproliferative disease in a patient with rheumatoid arthritis.

A 56-year-old woman was treated for rheumatoid arthritis for 17 years with methotrexate (MTX). Night sweats, fever and weight loss made her visit our hospital. Although levofloxacin failed to resolve her fever, she was suspected of having sepsis because of pancytopenia, elevated procalcitonin and a nodular lesion in the lung.

Long-term peritoneal dialysate exposure modulates expression of membrane complement regulators in human peritoneal mesothelial cells.

The membrane complement regulators (CRegs) CD46, CD55, and CD59 are highly expressed on human peritoneal mesothelial cells. However, how mesothelial CRegs change according to the peritoneal dialysis (PD) history of patients has remained unclear. We therefore examined longitudinal changes in CRegs in primary cultured mesothelial cells from PD patients (human peritoneal mesothelial cells; HPMCs) and examined which components of PD fluid (PDF) affect CRegs .

Long-term outcomes of oligometastatic breast cancer patients treated with curative intent: an updated report.

Background: Oligometastatic breast cancer (OMBC) is characterized by limited metastatic tumor numbers and sites. We have reported a 20-year overall survival (OS) rate and relapse-free rate (RFR) of 34.1% and 27.

Strong impact of pathological node-negative on long-term overall survival of patients with triple-negative breast cancer receiving neoadjuvant chemotherapy.

Triple-negative breast cancer (TNBC) has a high pathological complete response (pCR) rate; however patients without a high pCR are reported to have a poor prognosis. The current study investigated the long-term overall survival of patients with TNBC who received neoadjuvant chemotherapy (NAC) and analyzed various prognostic factors including basal marker and claudin expressions. Between November 2005 and March 2012, the current study retrospectively reviewed the records of 323 patients with breast cancer who received anthracycline followed by taxane as NAC at the Jikei University Hospital Basal marker and claudin expression was determined via immunohistochemistry.

Laparoscopic treatment of a solitary fibrous tumor originating in the cystic plate.

Background: Solitary fibrous tumor (SFT) is a rare mesenchymal tumor originating from the tissue underlying the mesothelial layer of the pleura or mediastinum. Other reported sites include the upper respiratory tract, orbit, thyroid, peritoneum, and central nervous system.

Case Presentation: We describe a case of a 7 cm SFT that originated in the cystic plate.

Differential clinical features of patients with clinically amyopathic dermatomyositis who have circulating anti-MDA5 autoantibodies with or without myositis-associated autoantibodies.

Background: Anti-melanoma differentiation-associated gene 5 (MDA5) autoantibodies have been identified as myositis-specific autoantibodies that are often associated with clinically amyopathic dermatomyositis (CADM) and a poor prognosis due to rapidly progressive interstitial lung disease (RP-ILD) in East Asian patients. Besides anti-MDA5 autoantibodies, patients with CADM may have myositis-associated autoantibodies (MAAs), which characterize other connective tissue diseases such as rheumatoid arthritis and Sjögren's syndrome. However, the clinical significance of the coexistence of anti-MDA5 autoantibodies and MAAs in patients with CADM remains unclear.

Selenolactams as Synthetic Intermediates for the Synthesis of Polycyclic Amines via Seleno-Claisen Rearrangements.

A highly diastereoselective α-allylation of selenolactams with allyl halides is reported. DFT analyses and experimental observations suggested that this reaction proceeds via a Se-allylation of the eneselenolates of the lactams followed by a seleno-Claisen rearrangement. The thus-obtained products could be efficiently transformed into polycyclic amines using a previously developed sequential addition of organometallic reagents and ring-closing metathesis.

All-Dielectric Dual-Color Pixel with Subwavelength Resolution.

An all-dielectric optical antenna supporting Mie resonances enables light confinement below the free-space diffraction limit. The Mie scattering wavelengths of the antenna depend on the structural geometry, which allows the antennas to be used for colored imprint images. However, there is still room for improving the spatial resolution, and new polarization-dependent color functionalities are highly desirable for realizing a wider color-tuning range.

Clinicopathological Features of Thymoma with Ring Calcification: Case Reports.

Thymomas with ring calcifications are very rare and quaint style. Herein, we presented our three cases of thymomas with ring calcifications and reviewed totally 10 cases including 7 cases of previous English literatures. The median age was 53 years.

[A Case of Metastatic Tubulocystic Carcinoma of the Kidney Treated with Molecularly Targeted Therapy].

A 51-year-old man who presented with gross hematuria and back pain was found to have a right renal mass accompanied with lung and osseous metastases. The patient underwent transabdominal right nephrectomy. The histopathological examination revealed the tumor to be tubulocystic carcinoma of the kidney.

Immunohistochemical Analysis of Debris Captured by Filter-Type Distal Embolic Protection Devices for Carotid Artery Stenting.

Background: Little is known about the micro-debris captured in filter-type distal embolic protection devices (EPD) used for carotid stenting (CAS). This study aimed to determine the histological and immunohistochemical characteristics of such debris by using a new liquid-based cytology (LBC) technique.

Methods: Fifteen patients who underwent CAS using a filter-type distal EPD (FilterWire EZ; Boston Scientific, Marlborough, MA, USA) were included in the study.

Expression of immune checkpoint molecules of T cell immunoglobulin and mucin protein 3/galectin-9 for NK cell suppression in human gastrointestinal stromal tumors.

Monoclonal antibody therapy for immune checkpoint blockade has achieved promising results for several types of malignant tumors. For the future treatment of gastrointestinal stromal tumors (GISTs) by immune checkpoint blockade, expression of immune checkpoint-related molecules that suppress antitumor immunity in GISTs was examined. Infiltration of immune cell types into 19 GIST tissues was analyzed by immunohistochemistry, and expression of T cell immunoglobulin and mucin protein 3 (Tim-3) and programmed cell death-1 (PD-1) in the infiltrated immune cells was examined by immunofluorescence microscopy.

A case of Trousseau syndrome caused by pulmonary adenocarcinoma that was controlled for one year and 10 months with thrombosis treatment using an EGFR tyrosine kinase inhibitor and chemotherapy.

A 47-year-old female with no history of previous illnesses developed cerebral infarction and was diagnosed with lung cancer, specifically EGFR mutation-positive adenocarcinoma, and Trousseau syndrome. The patient's response to anticoagulant therapy with non-fractionated heparin was very poor; however we were able to control the thrombosis with chemotherapy. She survived for one year and 10 months following treatment with gefitinib, CBDCA + PEM and erlotinib, without recurrence of thrombosis.

A case of anti-MDA5-positive rapidly progressive interstitial lung disease in a patient with clinically amyopathic dermatomyositis ameliorated by rituximab, in addition to standard immunosuppressive treatment.

Rapidly progressive interstitial lung disease (RP-ILD) in patients with clinically amyopathic dermatomyositis (CADM) associated with antibodies to melanoma differentiation-associated gene5 (MDA5) results in a high mortality rate. We experienced a case of anti-MDA5-positive RP-ILD of CADM which showed a response to rituximab, although there was no significant effect due to standard immunosuppressive treatment. This case suggests that rituximab has the potential to offer an effective agent for the treatment of anti-MDA5-positive RP-ILD of CADM.

Morphological study of the TK cholangiocarcinoma cell line with three-dimensional cell culture.

Cholangiocarcinoma is an intractable carcinoma originating from the bile duct epithelium. To gain an understanding of the cell biology of cholangiocarcinoma, in vitro cell culture is valuable. However, well‑characterized cell lines are limited.

Vesnarinone suppresses TNFα mRNA expression by inhibiting valosin-containing protein.

Vesnarinone is a synthetic quinolinone derivative used in the treatment of cardiac failure and cancer. It is also known to cause agranulocytosis as a side effect, which restricts its use, although the mechanism underlying agranulocytosis is not well understood. Here, we show that vesnarinone binds to valosin-containing protein (VCP), which interacts with polyubiquitinated proteins and is essential for the degradation of IκBα to activate nuclear factor (NF)κB.

Possible clinical cure of metastatic breast cancer: lessons from our 30-year experience with oligometastatic breast cancer patients and literature review.

Background: Metastatic breast cancer (MBC) is generally incurable. However, 10-20-year relapse-free survival of MBC is approximately 2%, implying that at least a small subset of MBC patients achieve prolonged survival. We therefore analyzed long-term outcome in a particular subset, i.

Preoperative diagnosis of early cystic duct cancer using endoscopic ultrasonography and endocholangioscopy: report of a case.

Primary cystic duct carcinoma is a rare condition, for which preoperative diagnosis is difficult. We herein report a case of early primary carcinoma of the cystic duct, which was diagnosed preoperatively using endoscopic ultrasonography and endocholangioscopy. A 76-year-old man was admitted to our hospital with epigastric pain and liver dysfunction.

Impact of CD44+CD24- cells on non-sentinel axillary lymph node metastases in sentinel node-positive breast cancer.

Although complete axillary lymph node dissection (ALND) is the standard for evaluating axillary status after the identification of a positive sentinel lymph node (SLN) in breast cancer; approximately 40-60% of SLN-positive patients have negative non-SLN. In this study, to explore putative breast cancer stem cells with CD44+CD24- in the SLN, we retrospectively analyzed the expression of CD44+CD24- on metastatic tumor cells within SLNs as a predictive factor for positive non-SLNs (NSLNs). We tested 271 patients for SLNs using serial sectioning with cytokeratin immunohistochemistry (IHC) and hematoxylin-eosin staining and identified 67 patients who had a positive SLN biopsy and complete ALND.

EGFR as paradoxical predictor of chemosensitivity and outcome among triple-negative breast cancer.

We retrospectively analyzed the expression of epidermal growth factor receptor (EGFR) as a prognostic marker to predict neoadjuvant chemotherapy response and survival among breast cancer subtypes. We used immunohistochemical profiles to subtype the patients. EGFR expression was determined using immunohistochemistry.

The predictive value of PgR and HER-2 for response to primary systemic chemotherapy in inflammatory breast cancer.

Background: Inflammatory breast cancer (IBC) is the most aggressive form of primary breast cancer. We examined the relationship between clinicopathological factors and clinical response to primary systemic chemotherapy (PSC) and outcome.

Methods: Twenty-five patients with IBC were examined.

Development of a chemical screening system using aqueorin-fused protein.

We developed a unique screening system that consists of combination of high photo-sensitivity of photoprotein aequorin (AQ) and our developed high-performance affinity purification system. In the present study, we demonstrated to detect the specific interaction between methotrexate (MTX) and its target dihydrofolate reductase (DHFR) fused with AQ. We succeeded to prepare highly purified AQ-fused DHFR, which showed high sensitive light emission.
