AIMS: Intestinal metaplasia and atrophy of the gastric mucosa are associated with Helicobacter pylori infection and are considered premalignant lesions. The updated Sydney system is used to these parameters but experienced pathologists and consensus processes are required for interobserver agreement. We sought to determine the influence of consensus process on assessment of intestinal metaplasia and atrophy. METHODS AND RESULTS: Two study sets were used; consensus set and validation set...

Although a founder variant of RNF213 4810G>A is a major genetic risk factor for moyamoya disease (MMD) in East Asians, the frequency and disease susceptibility of RNF213 variants remain largely unknown. This study investigated the mutation analysis of RNF213 (4448, 4810, 4863, and 4950) between Korean MMD and healthy controls. We performed a polymerase chain reaction-restriction fragment length polymorphism analysis. To identify the association between RNF213 gene polymorphisms and MMD disease, we performed statistical analyses such as multivariable logistic regression and Fisher's exact test...

A Gram-stain-negative, non-motile and aerobic bacterial strain, designated L1 8-17(T), was isolated from a marine alga, Porphyridium marinum, in South Korea. Cells of strain L1 8-17(T) were found to be oxidase- and catalase-positive cocci without flagella. Growth of strain L1 8-17(T) was observed at 20-40 °C (optimum, 37 °C), pH 6.0-10.0 (optimum, pH 7.0-8.0) and in the presence of 0-7 % (w/v) NaCl (optimum, 2-3 %). The isoprenoid quinone detected was only ubiquinone-10. Summed feature 8 (comprising C18 : 1ω7c/C18 : 1ω6c) and C16 : 0 were detected as major cellular fatty acids...

A reddish pink-pigmented, Gram-stain-negative, aerobic and methylotrophic bacterial strain, designated strain IER25-16(T), was isolated from a laboratory air conditioning system in the Republic of Korea. Cells were motile rods showing catalase- and oxidase-positive reactions. Strain IER25-16(T) grew at 10-40 °C (optimum, 30 °C), at pH 4.0-7.0 (optimum, pH 5.0-7.0) and in the presence of 0-1.0 % (w/v) NaCl (optimum, 0 %).

Particle size of biochar may strongly affect the kinetics of hydrophobic organic compound (HOC) sorption. However, challenges exist in characterizing the effect of biochar particle size on the sorption kinetics because of the wide size range of biochar. The present study suggests a novel method to determine a representative value that can be used to show the dependence of HOC sorption kinetics to biochar particle size on the basis of an intra-particle diffusion model. Biochars derived from three different feedstocks are ground and sieved to obtain three daughter products each having different size distributions...

Despite expressing high levels of the epidermal growth factor receptor (EGFR), a majority of oral squamous cell carcinoma (OSCC) patients show limited response to cetuximab and ultimately develop drug resistance. However, mechanism underlying cetuximab resistance in OSCC is not clearly understood. Here, using a mouse orthotopic xenograft model of OSCC, we show that BMP7-p-Smad1/5/8 signaling contributes to cetuximab resistance. Tumor cells isolated from the recurrent cetuximab-resistant xenograft models exhibited low EGFR expression but extremely high levels of phosphorylated Smad-1, -5, and -8 (p-Smad1/5/8)...

The application of biochar (BC) as a filler in polymers can be viewed as a sustainable approach that incorporates pyrolysed waste based value-added material and simultaneously mitigate bio-waste in a smart way. The overarching aim of this work was to investigate the electrical, mechanical, thermal and rheological properties of biocomposite developed by utilizing date palm waste-derived BC for the reinforcing of polypropylene (PP) matrix. Date palm waste derived BC prepared at (700 and 900°C) were blended at different proportions with polypropylene and the resultant composites (BC/PP) were characterized using an array of techniques (scanning electron microscope, energy-dispersive X-ray spectroscopy and Fourier transform infra-red spectroscopy)...

The POU transcription factor OCT4 is critical for maintaining the undifferentiated state of embryonic stem cells (ESCs) and generating induced pluripotent stem cells (iPSCs), but its precise mechanisms of action remain poorly understood. Here, we investigated the role of OCT4 phosphorylation in the biological functions of ESCs. We observed that c-Jun N-terminal kinases (JNKs) directly interacted with and phosphorylated OCT4 at serine 347, which inhibited the transcriptional activity of OCT4. Moreover, phosphorylation of OCT4 induced binding of FBXW8, which reduced OCT4 protein stability and enhanced its proteasomal degradation...

In order to decrease donors' exposure to granulocyte-colony stimulating factor (G-CSF), we compared the effect of two versus three days of G-CSF priming on CD34+ yield in bone marrow (BM) harvest. Although the number of BM-CD34+ cells was higher in 3day G-CSF priming, we achieved the same number of CD34+ cells per recipient's weight in 2day G-CSF priming group, too. In addition, the number of total nucleated cells (TNC) harvested from BM were similar with two or three day regimen. But mononuclear cells (MNC) of the BM graft was higher in the 3day G-CSF priming group...

Programmed cell death 1 (PD-1) and its ligands PD-L1/PD-L2 have been shown to mediate immune evasion in various cancers, but their prognostic implications in patients with primary central nervous system lymphoma (PCNSL) are poorly understood. Therefore, we analyzed 76 PCNSL patients at initial diagnosis who were treated homogenously with high-dose methotrexate-based chemotherapy, and evaluated the prognostic roles of high immunohistochemical PD-1, PD-L1, and PD-L2 expression. The cut-off values for high PD-1 (≥ 70 cells/high power field [HPF]), PD-L1 (≥ 100 cells/HPF), and PD-L2 (≥ 100 cells/HPF) were determined by the area under the receiver operating characteristic curve...

Expansin act by loosening hydrogen bonds in densely packed polysaccharides. This work characterizes the biological functions of expansin in the gelling and degradation of algal polysaccharides. In this study, the bacterial expansin BpEX from Bacillus pumilus was fused with the dockerin module of a cellulosome system for assembly with agarolytic complexes. The assembly of chimeric expansin caused an indicative enhancement in agarase activity. The enzymatic activities on agar substrate and natural biomass were 3...

PURPOSE: The objective of this study was to evaluate the efficacy and tolerability of a triple combination of amlodipine/losartan/rosuvastatin in patients with hypertension and hypercholesterolemia. METHODS: A randomized, multicenter, double-blind, placebo-controlled study was conducted. Eligible patients with hypertension and a sitting diastolic blood pressure (SiDBP) of >90 mm Hg and LDL-C levels <250mg/dL were screened. After a 4-week run-in period with therapeutic lifestyle changes and losartan potassium 100mg once daily, patients who met both blood pressure criteria (80 mm Hg ≤ SiDBP < 110 mm Hg) and the LDL-C level criteria (defined in the National Cholesterol Education Program Adult Treatment Panel III cardiovascular risk categories) were randomized to 1 of 3 groups and treated once daily for 8 weeks: losartan potassium 100mg + rosuvastatin 20mg treatment (L/R 100/20) group, amlodipine camsylate 5mg + losartan potassium 100mg treatment (A/L 5/100) group, and amlodipine 5mg+ losartan potassium 100mg + rosuvastatin 20mg (A/L/R 5/100/20) group...

Soil washing residue (SWR), which typically concentrates the washed toxic metals and is comprised of high contents of clay particles, may pose risks to the surrounding environment. This study aims to simulate accelerated ageing to assess the stability of selected metals (Cd(2+) (132mg/kg), Cu(2+) (248mg/kg) and Pb(2+) (3470mg/kg)) in a SWR (89.68% of clay) with and without biochar treatment. The soil was incubated under constant moisture and wet-dry cycles (accelerated ageing), respectively, and the mobility and fractions of heavy metals in the soils with and without biochar treatment were examined...
