Subclinical hypothyroidism (SCH) is a common problem in pediatric population, and the natural history of SCH varies depending on its etiology. Whether Hashimoto's thyroiditis (HT) negatively affects the natural course of SCH was investigated in pediatric patients without concomitant diseases. Predictors for levothyroxine medication were also evaluated. Medical records of 109 children with SCH (91 girls, 5?18 years) diagnosed between 2005 and 2014 were retrospectively reviewed. Patients were classified into HT (n = 37) and isolated non-autoimmune hyperthyrotropinemia (iso-NAHT, n = 72)...

Bronchiolitis obliterans is a small-airway obstructive lung disease for which immunologically mediated pathogenesis is supposed. Frequent association of bronchiolitis obliterans with paraneoplastic pemphigus is well known, but its association with other autoimmune bullous diseases has not been reported except for a case of anti-laminin-332-type mucous membrane pemphigoid in a patient with chronic graft-versus-host disease. We report a case of non-paraneoplastic autoimmune subepidermal bullous disease associated with fatal bronchiolitis obliterans in a patient without transplantation...

Because the efficacy rates of monotherapy with immune checkpoint inhibitors such as nivolumab or ipilimumab are not sufficient, to enhance the antitumor effects of these reagents is of great interest among dermato-oncologists. In this report, we describe two cases of multiple in-transit metastatic melanomas on the leg successfully treated with intensity-modulated radiotherapy (IMRT) using a CyberKnife in combination with ipilimumab or nivolumab. Our cases suggested that IMRT could enhance the antitumor effects of immune checkpoint inhibitors in patients with multiple in-transit melanomas...

Small airway fibrosis is a major pathologic feature of chronic obstructive pulmonary disease (COPD) and is refractory to current treatments. Chronic inflammatory cells accumulate around small airways in COPD and are thought to play a major role in small airway fibrosis. Mice deficient in α/β T-cells have recently been shown to be protected from both experimental airway inflammation and fibrosis. In these models, CD4+Th17 cells and secretion of IL-17A are increased. However, a pathogenic role for IL-17 in specifically mediating fibrosis around airways has not been demonstrated...

Half-filled electron systems, even with the maximized spin angular moment, have been given little attention because of their zero-orbital angular moment according to Hund's rule. Nevertheless, there are several measurements that show evidence of a nonzero orbital moment as well as spin-orbit coupling. Here we report for the first time the orbital order in a half-filled 4f-electron system GdB_{4}, using the resonant soft x-ray scattering at Gd M_{4,5}-edges. Furthermore, we discovered that the development of this orbital order is strongly coupled with the antiferromagnetic spin order...

There has been a strong demand in Japan and East Asia for L-glutamic acid as a seasoning since monosodium glutamate was found to present umami taste in 1907. The discovery of glutamate fermentation by Corynebacterium glutamicum in 1956 enabled abundant and low-cost production of the amino acid, creating a large market. The discovery also prompted researchers to develop fermentative production processes for other L-amino acids, such as lysine. Currently, the amino acid fermentation industry is so huge that more than 5 million metric tons of amino acids are manufactured annually all over the world, and this number continues to grow...

Engineering of monoclonal antibodies (mAbs) enables us to obtain mAbs with additional functions. In particular, modifications in antibody's Fc (fragment, crystallizable) region can provide multiple benefits such as added toxicity by drug conjugation, higher affinity to Fc receptors on immunocytes, or the addition of functional modules. However, the generation of recombinant antibodies requires multiple laborious bioengineering steps. We previously developed a technology that enables rapid in vitro screening and isolation of specific mAb-expressing cells from the libraries constructed with chicken B-cell line DT40 (referred to as the 'ADLib system')...

Piperonal-catabolizing microorganisms were isolated from soil, the one (strain CT39-3) exhibiting the highest activity being identified as Burkholderia sp. The piperonal-converting enzyme involved in the initial step of piperonal metabolism was purified from strain CT39-3. Gene cloning of the enzyme and a homology search revealed that the enzyme belongs to the xanthine oxidase family, which comprises molybdoenzymes containing a molybdopterin cytosine dinucleotide cofactor. We found that the piperonal-converting enzyme acts on piperonal in the presence of O2, leading to formation of piperonylic acid and H2O2...

Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant inherited disorder caused by germline mutations in the FLCN gene, and characterized by skin fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax, and renal neoplasms. Pulmonary manifestations frequently develop earlier than other organ involvements, prompting a diagnosis of BHDS However, the mechanism of lung cyst formation and pathogenesis of pneumothorax have not yet been clarified. Fibroblasts were isolated from lung tissues obtained from patients with BHDS (n = 12) and lung cancer (n = 10) as controls...

The aim of this study was to address 7-year clinical outcomes and impact of prolonged dual antiplatelet therapy (DAPT) after coronary stenting in hemodialysis patients. Our study included 123 consecutive hemodialysis patients who had undergone percutaneous coronary intervention with a drug-eluting stent (DES) or bare-metal stent (BMS) (DES: 64, BMS: 59) in our institution. We compared long-term clinical outcomes following DES with BMS implantation as well as clinical outcomes in patients on DAPT for ≥1 year (DAPT on group, 89) with those on DAPT for <1 year (DAPT off group, 34)...

The oncogenic transcription factor MYC and its binding partner MAX regulate gene expression by binding to DNA at enhancer-box (E-box) elements 5'-CACGTG-3'. In mammalian genomes, the central E-box CpG has the potential to be methylated at the 5-position of cytosine (5mC), or to undergo further oxidation to the 5-hydroxymethyl (5hmC), 5-formyl (5fC), or 5-carboxyl (5caC) forms. We find that MAX exhibits the greatest affinity for a 5caC or unmodified C-containing E-box, and much reduced affinities for the corresponding 5mC, 5hmC or 5fC forms...

Infertility associated with ovarian failure is a serious late complication for female survivors of allogeneic hematopoietic stem cell transplantation (SCT). While the role of pretransplant conditioning regimen has been well appreciated, increasing application of reduced-intensity conditioning facilitated us to revisit the other factors possibly affecting ovarian function after allogeneic SCT. We have addressed whether donor T-cell mediated graft-versus-host disease (GVHD) could be causally related to female infertility in mice...

OBJECTIVE In 1999, the World Health Organization categorized large cell neuroendocrine carcinoma (LCNEC) of the lung as a variant of large cell carcinoma, and LCNEC now accounts for 3% of all lung cancers. Although LCNEC is categorized among the non-small cell lung cancers, its biological behavior has recently been suggested to be very similar to that of a small cell pulmonary malignancy. The clinical outcome for patients with LCNEC is generally poor, and the optimal treatment for this malignancy has not yet been established...

Alginate-assimilating Sphingomonas sp. strain A1 is the gram-negative bacterium first identified to form a single polar flagellum containing lateral-typed flagellin (p6) in the filament. In addition to the p6 flagellin, two polar-typed flagellins (p5 and p5') are also included in the flagellum. Here we show the significant role of p6 as well as p5/p5' in flagellum formation and cell motility toward alginate. A p6 gene disruptant significantly reduced flagellum formation, and it showed no cell motility, whereas each mutant with a disruption in the p5 or p5' gene exhibited cell motility through the formation of a polar flagellum containing p6...

"Cell-in-cell" denotes an invasive phenotype in which one cell actively internalizes in another. The novel human T-cell line HOZOT, established from human umbilical cord blood, was shown to penetrate a variety of human cancer cells but not normal cells. Oncolytic viruses are emerging as biological therapies for human cancers; however, efficient viral delivery is limited by a lack of tumor-specific homing and presence of pre-existing or therapy-induced neutralizing antibodies. Here, we report a new, intriguing approach using HOZOT cells to transmit biologics such as oncolytic viruses into human cancer cells by cell-in-cell invasion...

This paper presents the aggregation-induced emission (AIE) properties of o-carborane derivatives and proposes a potential strategy for constructing AIE-active organoboron complexes via the enhancement of freedom of intramolecular mobility. Initially, the optical properties of o-carborane derivatives with or without the fused ring structure at the C-C bond in o-carborane in which elongation should be induced by photo-excitation according to theoretical calculations were compared. Accordingly, it was shown that large mobility at the C-C bond in o-carborane should be responsible for the annihilation of emission in solution, leading to the AIE property...
