BACKGROUND: Scalloped tongue is considered as a possible clinical finding of obstructive sleep apnea (OSA). There are few evidence of the association between scalloped tongue and OSA. OBJECTIVE: To examine the association between scalloped tongue and nocturnal intermittent hypoxia (NIH), a surrogate marker of OSA, among a general Japanese population. METHODS: Study participants were 398 men and 732 women aged 30-79 years who participated in the Toon Health Study from 2011 to 2014...

Human RING finger protein 141 (RFP141) is a germ cell-specific transcription factor during spermatogenesis. We synthesized a compact construct encoding the C-terminal zinc finger of RFP141 (RFP141C peptide). Herein we determined the solution structure of the RFP141C peptide by nuclear magnetic resonance (NMR). Moreover, NMR data and the chemical modification of cysteine residues demonstrated that the RFP141C peptide binds to two zinc atoms in a cross-brace arrangement. The Simple Modular Architecture Research Tool database predicted the structure of RFP141C as a RING finger...

In Japan, radiocesium contamination in foods has become of great concern and it is a primary issue to reduce grain radiocesium concentration in rice (Oryza sativa L.). Here, we report a low-cesium rice mutant 1 (lcs1) with the radiocesium concentration in grain about half that in the wild-type cultivar. Genetic analyses revealed that a mutation in OsSOS2, which encodes a serine/threonine-protein kinase required for the salt overly sensitive (SOS) pathway in plants, is responsible for the decreased cesium (Cs) concentrations in lcs1...

Cholangiocarcinoma is an epithelial malignancy arising in the region between the intrahepatic bile ducts and the ampulla of Vater at the distal end of the common bile duct. The effect of current chemotherapy regimens against cholangiocarcinoma is limited, and the prognosis of patients with cholangiocarcinoma is poor. Aberrant DNA methylation and histone modification induce silencing of tumor suppressor genes and chromosomal instability during carcinogenesis. Studies have shown that the tumor suppressor genes and microRNAs (miRNAs) including MLH1, p14, p16, death-associated protein kinase (DAPK), miR-370 and miR-376c are frequently methylated in cholangiocarcinoma...

AIMS: Traditional serrated adenoma (TSA) is a rare but distinct type of colorectal polyp. Our previous study showed that PTPRK-RSPO3 fusions are frequent and characteristic genetic alterations in TSAs. This study aimed to comprehensively characterize the prevalence and variability of RSPO fusions in colorectal TSAs. METHODS AND RESULTS: We examined RSPO expression and explored novel RSPO fusions in 129 TSAs, including 66 lesions previously analyzed for WNT pathway gene mutations...

Pulmonary emphysema impairs quality of life and increases mortality. Previous studies demonstrated that administration of KGF before elastase instillation prevented pulmonary emphysema in mice. We hypothesized that KGF could improve pulmonary function, and that the therapeutic administration of KGF would restore damaged lungs caused by elastase instillation in an animal model. We constructed KGF expressing adenovirus vector, which prevented bleomycin induced pulmonary fibrosis in the previous study. Adenovirus vector (1...

Although human term placenta-derived primary cytotrophoblasts (pCTBs) represent a good human syncytiotrophoblast (STB) model, in vitro culture of pCTBs is not always easily accomplished. Y-27632, a specific inhibitor of Rho-associated coiled-coil containing kinases (ROCK), reportedly prevented apoptosis and improved cell-to-substrate adhesion and culture stability of dissociated cultured human embryonic stem cells and human corneal endothelial cells. The Rho kinase pathway regulates various kinds of cell behavior, some of which are involved in pCTB adhesion and differentiation...

In this work, by combining transmission electron microscopy and polarized Raman spectroscopy for the 1T' MoTe2 flakes with different thicknesses, we found that the polarization dependence of Raman intensity is given as a function of excitation laser wavelength, phonon symmetry and phonon frequency, but has weak dependence on the flake thickness from few-layer to multilayer. In addition, the frequency of Raman peaks and the relative Raman intensity are sensitive to flake thickness, which manifests Raman spectroscopy as an effective probe for thickness of 1T' MoTe2...

Daurichromenic acid is a meroterpenoid with various pharmacological activities that is biosynthesized from grifolic acid in Rhododendron dauricum. Heterologous expression of grifolic acid synthases from Stachybotrys bisbyi and a daurichromenic acid synthase from R. dauricum in Aspergillus oryzae mediated three-step combinatorial biosynthesis of (+)-daurichromenic acid through enantioselective 6-endo-trig cyclization. Additional introduction of a halogenase from Fusarium sp. into the strain resulted in the biosynthesis of (+)-5-chlorodaurichromenic acid, which exceeds the antibacterial activity of the original compounds...

We performed a safety evaluation using the procedure devised by the Joint FAO/WHO Expert Committee on Food Additives of the following four flavouring substances that belong to the class of 'aliphatic primary alcohols, aldehydes, carboxylic acids, acetals, and esters containing additional oxygenated functional groups' and are uniquely used in Japan: butyl butyrylacetate, ethyl 2-hydroxy-4-methylpentanoate, 3-hydroxyhexanoic acid and methyl hydroxyacetate. Although no genotoxicity study data were found in the published literature, none of the four substances had chemical structural alerts predicting genotoxicity...

BACKGROUND: Scirrhous gastric cancer is an intractable disease with a high incidence of peritoneal dissemination and obstructive symptoms (e.g., ileus, jaundice, and hydronephrosis) arising from accompanying marked fibrosis. Microenvironmental interactions between cancer cells and cancer-associated fibroblasts are the suggested cause of the disease. We elucidated the mechanisms of tumor growth and fibrosis using human peritoneal mesothelial cells (HPMCs) and investigated the effects of tranilast treatment on cells and a xenograft mouse model of fibrosis...

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is systemic vascular inflammation. Microscopic polyangiitis (MPA) is a major type of AAV in Japan. MPA often affects the kidneys and lungs, leading to death if untreated. Induction therapy (i.e., initial treatment) for MPA has not been optimized, although methylprednisolone and cyclophosphamide are commonly used. Recently, rituximab (RTX) (a monoclonal antibody against the protein CD20) has also been used to treat refractory AAV. RTX at 375 mg/m(2)/week for 4 weeks (i...

A scenario tree model was developed to propose efficient bovine viral diarrhea (BVD) control measures. The model used field data in eastern Hokkaido where the risk of BVDV infection in cattle has been reduced by an eradication program including mass vaccination, individual tests prior to communal pasture grazing, herd screening tests using bulk milk, and outbreak investigations of newly infected herds. These four activities were then used as hypothesized control measures in the simulation. In each simulation, the numbers of cattle infected persistently and transiently with BVDV detected by clinical manifestations and diagnosis tests and of missed by all of the diagnosis tests were calculated, and the numbers were used as indicators to be compared for the efficacy of the control measures...

Nipah virus (NiV) is a zoonotic emerging paramyxovirus that can cause a fatal respiratory illness or encephalitis in humans. Despite many efforts, the molecular mechanisms of NiV-induced acute lung injury (ALI) remain unclear. We previously showed that NiV replicates to high titers in human lung grafts in NOD scid gamma mice, resulting in a robust inflammatory response. Interestingly, these mice can undergo human immune system reconstitution by the Bone marrow, Liver, and Thymus (BLT) reconstitution method, in addition to lung tissue engraftment, giving altogether a realistic model to study human respiratory viral infections...

Protein kinase C-ε (PKC-ε) at phagocytic cups mediates the membrane fusion necessary for efficient IgG-mediated phagocytosis. The C1B and pseudosubstrate (εPS) domains are necessary and sufficient for this concentration. C1B binds diacylglycerol; the docking partner for εPS is unknown. Liposome assays revealed that the εPS binds phosphatidylinositol 4-phosphate (PI4P) and PI(3,5)P2 Wortmannin, but not LY294002, inhibits PKC-ε concentration at cups and significantly reduces the rate of phagocytosis. As Wortmannin inhibits PI4 kinase, we hypothesized that PI4P mediates the PKC-ε concentration at cups and the rate of phagocytosis...
