Neomacrophorin X (1) was isolated from Trichoderma sp. 1212-03. Heteronuclear multiple bond correlation (HMBC) spectral analysis indicated a unique [4.4.3]propellane framework, which was verified by the (1)H and (13)C chemical shift calculations based on density functional theory (DFT) and subsequent comparison with experimental data obtained in CDCl3. The DFT-based electronic circular dichroism (ECD) calculations were effective in not only determining the absolute configuration but also confirming the relative structure...

Hashimoto's thyroiditis (HT) is characterized by dysregulated immune responses and is commonly associated with insulin resistance. However, the mechanism of insulin resistance in HT remains to be fully elucidated. The aim of the present study was to investigate the correlation between the percentage of B regulatory lymphocytes (Bregs) and insulin resistance in patients with HT but with normal thyroid function (type I). A total of 59 patients with type I HT and 38 healthy volunteers were enrolled in the study...

OBJECTIVE: The prevalence and clinical relevance of TSH-receptor (TSHR) blocking antibodies (TBAb) in patients with autoimmune thyroid disease (AITD) was investigated. METHODS: Serum TBAb were measured with a reporter gene bioassay using chinese hamster ovary cells. Blocking activity was defined as percentage inhibition of luciferase expression relative to induction with bovine TSH alone (cut-off 40% inhibition). All samples were measured for TSHR stimulatory Ab (TSAb) and TSHR binding inhibiting immunoglobulins (TBII)...

BACKGROUND: Additional chemotherapy is often not feasible in patients with recurrent malignant pleural mesothelioma (MPM) undergoing extrapleural pneumonectomy (EPP), due to deteriorated cardiopulmonary reserve. We thus examined the feasibility and efficacy of additional chemotherapy in patients with recurrent MPM after EPP. METHODS: A retrospective review was conducted of 59 consecutive patients who underwent bi-/tri-modal treatment with induction chemotherapy, EPP, and radiation therapy from July 2004 to August 2013 at Hyogo College of Medicine (Nishinomiya, Japan)...

Autoimmune thyroid diseases (AITD) are a group of both B cell- and T cell-mediated organ-specific autoimmune diseases. Graves' disease and Hashimoto thyroiditis are the two main clinical presentations of AITD. Both genetic and environmental factors have important roles in the development of AITD. Epigenetics have been considered to exert key roles in integrating those genetic and environmental factors, and epigenetic modifications caused by environmental factors may drive genetically susceptibility individuals to develop AITD...

Hepcidin is a liver-derived hormone that negatively regulates serum iron levels and is mainly regulated at the transcriptional level. Previous studies have clarified that in addition to hepatic iron levels, inflammation also efficiently increases hepatic hepcidin expression. The principle regions responsible for efficient hepcidin transcription are bone morphogenetic protein-responsive elements (BMP-REs) 1 and 2 as well as the signal transducer and activator of transcription 3-binding site (STAT-BS). Here, we show that the proinflammatory cytokine interleukin-1β (IL-1β) efficiently increases hepcidin expression in human HepG2 liver-derived cells and primary mouse hepatocytes...

A 12-year-old girl presented with a history of cervical mass, and one week of throat discomfort and dyspnea. Five years ago, the patient was diagnosed as Hashimoto's thyroiditis and hyperthyroidism; she received antithyroid drug treatment, but the result was not satisfactory. B-ultrasonic showed that the size of thyroid gland was 8.1 cm×3.2 cm in the left and 8.2 cm×4.8 cm in the right. After iodine 131 combined with radiofrequency ablation (RFA) treatment, throat discomfort and recumbent breathing difficulties disappeared, and B-ultrasonic showed that the size of thyroid reduced to 2...

The DNA damage response (DDR) plays a pivotal role in maintaining genome integrity. DNA damage and DDR activation are observed in the failing heart, however, the type of DNA damage and its role in the pathogenesis of heart failure remain elusive. Here we show the critical role of DNA single-strand break (SSB) in the pathogenesis of pressure overload-induced heart failure. Accumulation of unrepaired SSB is observed in cardiomyocytes of the failing heart. Unrepaired SSB activates DDR and increases the expression of inflammatory cytokines through NF-κB signalling...

BACKGROUND: Ventilatory anaerobic threshold (VAT) is frequently used as a measure of exercise tolerance, with the V-slope method being the standard; however, this needs to be visually determined. Over the years, we have observed that the V-slope itself often appears to shift rightward before the appearance of the VAT (RtShift: rightward shift of V-slope). This phenomenon has long been known to occur during the first 1-2 min of steady-state exercise and disappears thereafter; it is attributed to CO2 storage, presumably in active muscle...

Hashimoto encephalopathy (HE) is believed to be an immune-mediated disorder associated with Hashimoto's thyroiditis. It was suggested that neuropsychiatric symptoms, the presence of antithyroid antibody, and good response to steroids were important for the diagnosis of HE. It has been reported that homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylglycol (MHPG), which are monoamine metabolites of dopamine and noradrenaline, respectively, are the possible biomarkers of neuropsychiatric diseases. We report a case of Hashimoto encephalopathy, in which we longitudinally measured the plasma levels of monoamine metabolites...

Alcohol-use disorder (AUD) is a relapsing disorder associated with excessive ethanol consumption. Recent studies support the involvement of epigenetic mechanisms in the development of AUD. Studies carried out so far have focused on a few specific epigenetic modifications. The goal of this project was to investigate gene expression changes of epigenetic regulators that mediate a broad array of chromatin modifications after chronic alcohol exposure, chronic alcohol exposure followed by 8 h withdrawal, and chronic alcohol exposure followed by 21 days of abstinence in Withdrawal-Resistant (WSR) and Withdrawal Seizure-Prone (WSP) selected mouse lines...

Glycosaminoglycans (GAGs), such as hyaluronan, chondroitin sulfate, and heparin, constitute mammalian extracellular matrices. The uronate and amino sugar residues in hyaluronan and chondroitin sulfate are linked by 1,3-glycoside bond, while heparin contains 1,4-glycoside bond. Some bacteria target GAGs as means of establishing colonization and/or infection, and bacterial degradation mechanisms of GAGs have been well characterized. However, little is known about the bacterial import of GAGs. Here, we show a GAG import system, comprised of a solute-binding protein (Smon0123)-dependent ATP-binding cassette (ABC) transporter, in the pathogenic Streptobacillus moniliformis...

The aim of this study was first to investigate the oxidative proteins modifications in the plasma of both autoimmune thyroid diseases (AITD), Graves' disease (GD) and Hashimoto Thyroiditis (HT). Then, the impact of these oxidative modifications on immune response was evaluated by measuring the reactivity of patients' autoantibodies against malondialdéhyde (MDA) and Hydrogen peroxide (H2O2) modified thyroid antigens (T.Ag) in comparison to native ones. Carbonyl and thiol groups, and MDA-protein adducts were first assessed among 74 AITD patients and 65 healthy controls...

BACKGROUND: Mesenchymal stem cells (MSCs) are multipotent stem or stromal cells found in multiple tissues. Intravenous MSC injections have been used to treat various diseases with an inflammatory component in animals and humans. Inflammation is emerging as a key component of pathophysiology of intracranial aneurysms. Modulation of inflammation by MSCs may affect sustained inflammatory processes that lead to aneurysmal rupture. OBJECTIVE: To assess the effect of MSCs on the development of aneurysm rupture using a mouse model...
