To analyze the heterogeneity of anti-TSH receptor antibodies (TSHRAb), we measured serum TSH-binding inhibitory immunoglobulin (TBII), thyroid-stimulating antibody (TSAb), and thyroid stimulation blocking (TSBAb) activities in 31 patients with positive TSHRAb, using CHO cells expressing wild-type TSHR (WT) or chimera (Mc2) wherein residues 90-165 were substituted by LH/CG receptor. Using membranes from WT cells, detected TBII activity all patients; 10 (32%), TSAb only, completely lost Mc2...

We examined the relationship between blocking type anti-TSH receptor antibody (TRAb) and stimulating TRAb by trying to convert stimulatory in vitro. Immunoglobulins (IgGs) purified from sera of six patients with primary hypothyroidism blocked bovine TSH (100 microU/ml)-induced cAMP production (58.3-82.1% inhibition) cultured porcine thyroid cells. None these IgGs showed activity even after their dilution. In conversion experiment, cells were first incubated at 34 degrees C for 30 min then...
A validation study on an in vitro skin irritation assay was performed with the reconstructed human epidermis (RhE) LabCyte EPI-MODEL24, developed by Japan Tissue Engineering Co. Ltd (Gamagori, Japan). The protocol that followed current optimised version of EpiSkin (LabCyte assay).

Abstract Immunization of AKR/N mice with murine fibroblasts, transfected the TSH receptor (TSHR) and a major histocompatibility complex class II molecule having same H-2k haplotype (but not either alone), induces immune thyroid disease humoral histological features human Graves’, including presence two different TSHR antibodies (TSHRAbs): stimulating TSHRAbs, which cause hyperthyroidism; TSH-binding-inhibiting immunoglobulins. The primary functional epitope for both types in Graves’ patients...
Psoriasis is a systemic, chronic, immunologically-mediated disease affecting approximately 2%-4% of the worldwide population. It well known that psoriasis associated with several comorbidities such as metabolic syndrome, cardiovascular disease, and malignancy. Although meta-analyses large prospective cohort studies have shown an increased risk malignancies in patients worldwide, association between malignancy onset has not yet been established Japan. We retrospectively analyzed 360 at our...
The effects of bovine thyrotropin (TSH) on DNA synthesis and cyclic AMP production were studied in porcine thyroid follicles using suspension culture. During the early 72 hours incubation, time-dependent uptake [3H] thymidine by was obserbed. In presence 10mU/ml TSH, significantly depressed at 72hours incubation. TSH inhibition incorporation related to its concentration 50% observed 1.0mU/ml TSH.Under same conditions, stimulated stimulation be concentration. these experiments, incubation...

Abstract Phototherapy and apremilast (oral phosphodiesterase‐4 inhibitor) are well‐known in the treatment of moderate to severe psoriasis vulgaris. However, current evidence on efficacy safety their combination is not sufficient. This multicenter, randomized controlled study compared between phototherapy as monotherapy therapy patients with Patients vulgaris were assigned ( n = 29) 13) groups. All underwent an 8‐week regimen comprising irradiation narrowband UV‐B. The group also administered...
Extended X-ray absorption fine structure (EXAFS) spectroscopy is demonstrated to measure the atomic of SiO2–SiC interfaces. The SiC-side interface can be measured by fabricating thin SiO2 films and using SiC-selective EXAFS measurements. Fourier transforms oscillations spectra correspond radial-structure functions reveal a new peak first nearest neighbor Si for m-face SiC, which does not appear in measurements Si-face. This finding suggests that could include with shorter Si–C distances....

Chemical-state-selective Si K-edge extended X-ray absorption fine structure (EXAFS) measurements of SiO2 and SiC are demonstrated by detecting bond-specific Auger electrons in coated with a very thin film. Differential-electron-yield (DEY) mode is used for the measurements. Each EXAFS spectrum may be subject to following two spectrally overlapping influences: (i) background formed energy-losing overlaps peak, (ii) resonant peak peak. The SiO2- SiC-selective DEY–EXAFS spectra differ from each...
We have demonstrated the detection of nanometer-scale current-leakage sites in electrically stressed gate SiO 2 films using a conductive atomic force microscope (C-AFM). Prior to C-AFM observations, metal-oxide-semiconductor capacitors were subjected constant-current Fowler-Nordheim (FN) stress. Details image contrasts and relationship between surface topography current examined. Two types contrast clearly observed image: sharp bright spot reflecting local leakage caused by hole trapping at...
