The anti-inflammatory effects of 3‑bromo‑5‑(ethoxymethyl)‑1,2‑benzenediol (BEMB) from Polysiphonia morrowii were evaluated in lipopolysaccharide (LPS)-induced RAW264.7 cells and zebrafish embryo. BEMB showed anti-inflammatory effects by inhibiting the production of nitric oxide (NO) and reactive oxygen species (ROS), and the expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) in the LPS-activated RAW264.7 cells and zebrafish embryo without cytotoxicity. Moreover, BEMB suppressed the protein and mRNA expression levels of nuclear factor (NF)-κB (p65 and inhibitor of NF-κB [IκB]-A) in RAW264...

Microalgae are promising feedstocks for sustainable and eco-friendly production of biomaterials, which can be improved by genetic engineering. It is also necessary to optimize the processes to produce biomaterials from engineered microalgae. We previously reported genetic improvements of an industrial microalga Nannochloropsis salina by overexpressing a basic helix-loop-helix transcription factor (NsbHLH2). These transformants showed improved growth and lipid production particularly during the early phase of culture under batch culture...

Hypermutagenesis refers to marked increase in the number of mutations due to continuous mutagenic process. Hypermutated tumors, have being found in several tumor types, are associated with inherited or acquired alterations in DNA repair pathways. Hypermutation has been observed in a subset of adult glioma patients as a direct result of temozolomide(TMZ)-induced mutagenesis. In present study, we have identified a rare subset of treatment-naïve adult gliomas with de novo hypermutator phenotype and explored the evolution of spontaneous and treatment-induced hypermutagenesis...

Levels of vitamin D and parathyroid hormone (PTH) are closely associated with renal function. We evaluated the associations among 25-hydroxyvitamin D (25OHD) levels, PTH levels, and mortality, and whether these associations varied by renal function. We used data from the Dong-gu Study, a population-based cohort in Korean adults. We analyzed the associations among intact PTH, 25OHD levels and mortality in 8580 participants. Hazard ratios (HRs) for mortality were calculated using Cox proportional hazards regression after adjusting for age, sex, month of sampling, lifestyle, and comorbidities...

BACKGROUND: Sapria is a distinctive and narrowly host-specific holoparasitic genus belonging to the Rafflesiaceae. Sapria himalayana, rare throughout its range from NE India, SW China, Thailand to Vietnam, is a little-understood species first recorded for Vietnam in 1959, and only recollected there over half a century later in February 2017. This has facilitated an assessment of its taxonomic identity and our understanding of its morphology and natural history aspects. RESULTS: Six populations of Sapria at Vietnam's Tuyền Lâm Lake, and another two populations at the Nam Ban Protection Forest and the Cam Ly area were found, in an area of about 20 km in radius...

In a previous study, we reported that α‑smooth muscle actin (α‑SMA), one of the mesenchymal marker proteins, is highly expressed in tamoxifen‑resistant breast cancer (TamR) cells. However, the exact mechanism of α‑SMA expression in TamR cells is not fully understood. Here, we investigated the effect of TP53 on α‑SMA expression in breast cancer cells. The levels of α‑SMA mRNA and protein expression were analyzed by real‑time PCR and western blotting, respectively. In estrogen receptor‑positive [ER(+)] breast cancer patients, aberrant α‑SMA expression was found to be associated with a poor prognosis...

Objectives: Kawasaki disease (KD) is an acute systemic vasculitis of unknown aetiology that affects infants and young children. Recent reports of elevated serum high mobility group box 1 (HMGB1) level during the acute phase of KD and its relationship to poor response to IVIG treatment suggest a possible association of HMGB1 polymorphisms with KD. We investigated the association between the polymorphisms of the HMGB1 gene, KD susceptibility, coronary artery lesions, and KD response to IVIG treatment...

We used high-quality ZnO nanostructures/graphene substrates for understanding the mechanisms of charge transfer (CT) that take place under nonplasmonic conditions. As the optimal conditions for CT processes are found, we studied the range of CT normal to the ZnO surface that is coated with nanoscale HfO2 layers with different thicknesses. We could observe that CT decays over a few nanometers. In addition, we also observed a unique oscillation of the SERS intensity in the atomically thin oxide layers, which reflects the quantum tunneling effects of CT electrons across the oxide layers...

The unique ability of retroviruses to integrate genes into host genomes is of great value for long-term expression in gene therapy, but only when integrations occur at safe genomic sites. To reap the benefit of using retroviruses without severe detrimental effects, we developed several murine leukemia virus (MLV)-based gammaretroviral vectors with safer integration patterns by perturbing the structure of the integrase via insertion of DNA-binding zinc-finger domains (ZFDs) into an internal position of the enzyme...

The risk of thromboembolisms during the post-cardioversion period is high. For patients with persistent atrial fibrillation (AF), anticoagulation with warfarin (INR 2.0~3.0) is recommended for at least three weeks prior and four weeks after cardioversion. We aimed to evaluate the efficacy of apixaban in preventing thromboembolic events during post-cardioversion. We enrolled 127 consecutive persistent AF patients (83 persistent, 44 longstanding persistent AF), scheduled to undergo cardioversion and were pretreated with apixaban...

The pathogenesis of hypertension is multifactorial in patients with chronic kidney disease (CKD). We explored the relative contribution of arterial stiffness and fluid overload to blood pressure (BP) in these patients. We evaluated 1531 patients from a prospective observational cohort study of high-risk patients with cardiovascular disease. BP, arterial stiffness, and volume status expressed as the extracellular water/total body water ratio (ECW/TBW) were measured by 24-h BP monitoring, pulse-wave velocity (PWV), and bioelectrical impedance analysis, respectively...

Neurofibromatosis type 1 (NF1) is a common tumor predisposition syndrome in which glioma is one of the prevalent tumors. Gliomagenesis in NF1 results in a heterogeneous spectrum of low- to high-grade neoplasms occurring during the entire lifespan of patients. The pattern of genetic and epigenetic alterations of glioma that develops in NF1 patients and the similarities with sporadic glioma remain unknown. Here, we present the molecular landscape of low- and high-grade gliomas in patients affected by NF1 (NF1-glioma)...
