Superior Capsule Reconstruction for Irreparable Rotator Cuff Tears Yields Good Clinical Outcomes for Patients With and Without Diabetes Mellitus.

Purpose: To compare the clinical outcomes after superior capsule reconstruction (SCR) for irreparable rotator cuff tears (RCTs) in patients with and without diabetes mellitus (DM).

Methods: Patients who underwent SCR using fascia lata autograft for irreparable RCTs between 2012 and 2020 with a minimum 2-year follow-up were divided into non-DM and DM groups. Propensity score matching was used to select controls matched for patients' characteristics.

Stage III Chorioamnionitis is Associated with Reduced Risk of Severe Retinopathy of Prematurity.

Objective: To identify whether histologically confirmed chorioamnionitis (hCAM) is associated with development of retinopathy of prematurity (ROP).

Study Design: We retrospectively analyzed 2 different cohorts. Cohort 1 was the national database of newborns in Japan born at ≤1500g or <32 weeks' gestation (January 2003 through April 2021, n = 38 013).

Methylation levels of the IL10 gene in peripheral blood are related to the intractability of Graves' disease.

The prognosis of autoimmune thyroid diseases (AITDs), including Hashimoto's disease (HD) and Graves' disease (GD), is difficult to predict. DNA methylation regulates gene expression of immune mediating factors. Interleukin (IL)-10 is a Th2 cytokine that downregulates inflammatory cytokines produced by Th1 cells.

Clinical Usefulness of T-Cell Receptor Vβ Repertoire Analysis for Differentiating Multisystem Inflammatory Syndrome in Japanese Children From Toxic Shock Syndrome and Kawasaki Disease.

The specific expansion of T-cell receptor β chain variable region (TCR-Vβ21.3 + ) CD4 + and CD8 + T cells was observed in Japanese patients with multisystem inflammatory syndrome in children. In contrast, these findings were not observed in patients with toxic shock syndrome and Kawasaki disease.

Association of B7H3 and B7H4 gene polymorphisms and protein expression with the development and prognosis of autoimmune thyroid diseases.

Background: The prognosis of autoimmune thyroid diseases (AITDs), including Graves' disease (GD) and Hashimoto's disease (HD), varies among patients. B7-H3 and B7-H4, members of the B7 family of proteins, regulate immune response. To clarify the association of B7-H3 and B7-H4 with the pathogenesis and prognosis of AITDs, we examined the expression of the soluble and membrane form of B7-H3 and B7-H4 and genotyped single nucleotide polymorphisms (SNPs) in the B7H3 and B7H4 genes.

Transcriptome analysis of umbilical cord mesenchymal stem cells revealed fetal programming due to chorioamnionitis.

Although chorioamnionitis (CAM) has been demonstrated to be associated with numerous short- and long-term morbidities, the precise mechanisms remain unclear. One of the reasons for this is the lack of appropriate models for analyzing the relationship between the fetal environment and chorioamnionitis and fetal programming in humans. In this study, we aimed to clarify the fetal programming caused by CAM using the gene expression profiles of UCMSCs.

Current status of eye disorders caused by docetaxel administration every 3 weeks: A case-control study in Japanese patients.

Purpose: Docetaxel is known to cause eye disorders. In this study, current status of eye disorders caused by docetaxel administration every 3 weeks in Japanese patients was examined.

Methods: This case-control study targeted patients who were newly administered docetaxel at the Kyoto Okamoto Memorial Hospital between 1 July 2015 and 30 June 2018.

Risk Factors for Eye Disorders Caused by Paclitaxel: A Retrospective Study.

Paclitaxel and nanoparticle albumin-bound paclitaxel are known to cause adverse events of eye disorders, such as cystoid macular edema. However, at present, the risk factors remain unclear. Therefore, risk factors for eye disorders caused by paclitaxel and nanoparticle albumin-bound paclitaxel were studied.

Hematopoietic cell transplantation for myeloid/NK cell precursor acute leukemia in second remission.

Myeloid/natural killer cell precursor acute leukemia (MNKPL) is a rare leukemia subtype characterized by a high incidence of extramedullary infiltration. No appropriate treatment strategy has so far been developed. Acute myelogenous leukemia-type chemotherapy combined with L-Asparaginase is an effective treatment for MNKPL.

[An Undeniable Case of Optic Neuropathy Due to Cabazitaxel].

Cabazitaxelis a taxane-type antineoplastic agent used for treating prostate cancer. Although typical side effects include neutropenia and fatigue, no studies have investigated eye disorders as a possible side effect, and the details are not clear. Herein, we report our experience of an undeniable case of optic neuropathy caused by cabazitaxel.

[A Retrospective Analysis of Epiphora Due to Docetaxel].

Docetaxel is an antineoplastic agent used to treat breast cancer and several other types of cancer. Typical adverse drug reactions with docetaxel include myelosuppression and edema, but there have also been numerous reports of eye disorders, such as epiphora and lacrimal duct obstruction. Reports from Japan on such reactions, however, are limited; the duration and frequency of their appearance and other factors have not been elucidated.

[A Retrospective Analysis of Eye Disorders Due to Oxaliplatin].

In recent years, the incidence of eye disorders due to antineoplastic agents such as S-1 has increased. Eye disorders including visual field defect, visual field impairment, optic neuritis, and visual acuity reduction have been reported as serious adverse effects of oxaliplatin, an agent that is frequently used as a standard therapy for colorectal cancer. However, specific details about these conditions, such as the timing relative to oxaliplatin administration and frequencies at which they appear, remain to be clarified; therefore, we conducted a retrospective analysis of patients with eye disorders due to oxaliplatin in order to obtain evidence that would be useful in routine medical practice.

[A case of lacrimal duct obstruction caused by capecitabine].

In recent years, the incidence of adverse ocular reactions, including corneal problems and lacrimal duct obstruction, due to antineoplastic agents such as S-1 has increased. Very few reports of adverse ocular reactions caused by capecitabine, a fluorinated pyrimidine antineoplastic agent like S-1, exist, and consequently, the mechanism underlying these reactions is not well understood. This report describes our recent experience with a case of lacrimal duct obstruction caused by capecitabine.

[Survey of the current status of capecitabine-induced hypertriglyceridemia].

We encountered cases of capecitabine-induced increase in blood triglyceride (TG) levels, which is relatively rare in routine medical practice. Although capecitabine-induced hypertriglyceridemia (CI-HTG) has been occasionally reported in other countries, such cases have not been reported in Japan. Therefore, the details of this condition remain to be clarified.

[A case of hepatitis B virus reactivation in a patient with prior resolved hepatitis B infection during bevacizumab plus FOLFIRI treatment].

Hepatitis Bvirus (HBV)reactivation induced by cancer chemotherapy is increasingly being observed. However, most reports of resolved HBV[hepatitis Bsurface antigen(HBs-Ag)negative and hepatitis Bsurface antibody(HBs-Ab)positive and/or hepatitis Bcore antibody(HBc-Ab)positive]infection involve patients with hematological malignancies, whereas few describe patients with solid cancers. In this study, we report our experience with a patient with resolved HBV infection who was undergoing bevacizumab plus FOLFIRI treatment for rectal cancer when HBV reactivation was noted.

[Survey of current status of adverse ocular reactions to paclitaxel and a retrospective analysis for aiding in early detection of adverse reactions].

We have observed several cases of adverse reactions to paclitaxel, including visual impairment and lacrimation. Therefore, we conducted a survey of the current status of adverse reactions to paclitaxel and also performed a retrospective analysis of the initial symptoms and the times of their appearance. Of the 22 study patients, 8(36.

Astrocytes protect neurons against methylmercury via ATP/P2Y(1) receptor-mediated pathways in astrocytes.

Methylmercury (MeHg) is a well known environmental pollutant that induces serious neuronal damage. Although MeHg readily crosses the blood-brain barrier, and should affect both neurons and glial cells, how it affects glia or neuron-to-glia interactions has received only limited attention. Here, we report that MeHg triggers ATP/P2Y1 receptor signals in astrocytes, thereby protecting neurons against MeHg via interleukin-6 (IL-6)-mediated pathways.

Morphology and physical-chemical properties of baked nanoporous frustules.

We investigated the morphology and physical-chemical properties of baked and unbaked nanoporous frustules. Scanning electron microscopy (SEM) observations showed that the nanoporous structures of frustules unchanged at 400 degrees C even after baking for 6 h. During baking at 800 degrees C, the frustule structures changed dramatically.

Visible light regulates neurite outgrowth of nerve cells.

The neurite outgrowth of PC12 cells on collagen-coated glass plates under light emitting diode (LED) irradiation at several wavelengths (i.e., 455, 470, 525, 600, 630, 880 and 945 nm) was investigated.

Diatom cells grown and baked on a functionalized mica surface.

We demonstrate the cultivation of diatom cells on a functionalized mica surface and the preparation of frustules on a mica surface by baking. Diatom cells were successfully grown on a mica surface treated with 3-aminopropyltriethoxysilane. After baking at 400 degrees C for 2 h, frustule structures without the organic components of the diatom cells were successfully observed by scanning electron microscopy and atomic force microscopy.

Molecular organizations of myofibrils of skeletal muscle studied by atomic force microscopy.

By applying AFM technology, we studied mechanical characteristics of myofibrils of skeletal muscle. The obtained results indicate that (1) the Z-band is the most rigid sarcomere component stabilizing the myofibril structures, (2) various filamentous components are inter-connected in sarcomere with sufficient mechanical strength to support the contractile force, and (3) the molecular structure of the overlap region between actin and myosin filaments is anisotropic. In any case the present studies clearly indicate that the AFM technique is a powerful tool to investigate the mechanical characteristics of sarcomere structure of muscle fiber.
