Modelling of a post-combustion CO2 capture process using extreme learning machine

% reduction of CO2 emission by 2050 comparing with the & Jie Zhang level in 1950 is set by the Intergovernmental Panel on Climate Change. Carbon capture and storage (CCS) has been widely believed as an

Changes in event-related potentials in patients with first-episode schizophrenia and their siblings

Background This study aimed to explore the characteristics of event-related potentials induced by facial emotion recognition in patients with first-episode schizophrenia and in their siblings. Methods In this case-control study, 30 first-episode schizophrenia patients, 26 siblings, and 30 healthy controls were enrolled. They completed facial emotion recognition tasks from the Ekman ...

HNRNPA2B1 regulates the epithelial–mesenchymal transition in pancreatic cancer cells through the ERK/snail signalling pathway

Background Heterogeneous nuclear ribonucleoprotein A2B1 (HNRNPA2B1) is closely related to tumour occurrence and development, oncogene expression, apoptosis inhibition and invasion and metastasis capacities. However, its function in the epithelial–mesenchymal transition (EMT) of pancreatic cancer is not fully understood. Methods By comparing various wild-type pancreatic cancer cell ...

Casticin induces apoptosis and G0/G1 cell cycle arrest in gallbladder cancer cells

Background Casticin, the flavonoid extracted from Vitex rotundifolia L, exerts various biological effects, including anti-inflammatory and anti-cancer activity. The aim of this study is to investigate the effects and mechanisms of casticin in human gallbladder cancer cells. Methods Human NOZ and SGC996 cells were used to perform the experiments. CCK-8 assay and colony formation ...

Effect of Base Oil Structure on Elastohydrodynamic Friction

The EHD friction properties of a wide range of base fluids have been measured and compared in mixed sliding–rolling conditions at three temperatures and two pressures. The use of tungsten carbide ball and disc specimens enabled high mean contact pressures of 1.5 and 2.0 GPa to be obtained, comparable to those present in many rolling bearings. The measurements confirm the importance ...

High platelet reactivity affects the clinical outcomes of patients undergoing percutaneous coronary intervention

Background The association of platelet reactivity and clinical outcomes, especially stent thrombosis, was not so clear. We sought to investigate whether high platelet reactivity affects clinical outcomes of patients with drug eluting stents (DESs) implantation. Methods All enrolled individuals treated with DESs implantation were evaluated by PL-11, using sequentially platelet ...

MoS2 with tunable surface structure directed by thiophene adsorption toward HDS and HER

MoS2 catalysts with more active sites and larger surface areas were successfully synthesized via a simple hydrothermal reaction method, and the surface structure of MoS2 was readily tailored by simply adding thiophene during the synthesis procedure. The MoS2 samples synthesized with thiophene, especially MoS2 prepared with 200 μL of thiophene, concomitantly exhibited better ...

Growth enhancing effect of LBL-assembled magnetic nanoparticles on primary bone marrow cells

pathogenesis and diagnostic method, bone scaffold material and bone repair. Jie Zhang received his BSc degree in biomedical engineering from Southeast University in 2013. Now he is pursuing his master degree

Analysis of gene expression in the midgut of Bombyx mori during the larval molting stage

Background Insects can be models for understanding human intestinal infection and pathology. Molting, a special period during which the old insect cuticle is shed and a new one is produced, is crucial for insect development. Holometabolous insects may experience several larva-to-larva moltings to become larger, a pupal molt and adult eclosion to become adults. During the larval ...

\(B^*_{s,d} \rightarrow \mu ^+ \mu ^-\) and its impact on \(B_{s,d} \rightarrow \mu ^+ \mu ^-\)

This study investigates \(B^*_{s,d}\rightarrow \mu ^+\mu ^-\) in the dimuon distributions and the hadronic contribution \(B_{s,d}\rightarrow B^*_{s,d}\gamma \rightarrow \mu ^+\mu ^-\). The \(\mu ^+\mu ^-\) decay widths of the vector mesons \(B^*_{s,d}\) are approximately a factor of 700 larger than the corresponding scalar mesons \(B_{s,d}\). The ratio of the branching fractions ...

Effects, safety, and plasma levels of topiroxostat and its metabolites in patients receiving hemodialysis

Background Serum uric acid concentrations have been associated with mortality in patients receiving hemodialysis. Treatment options are sometimes limited because of the accumulation of a drug and/or its metabolites. The aim of the present study is to investigate the efficacy, safety, and plasma levels of topiroxostat, a selective xanthine oxidase inhibitor, and its metabolites in ...

China suboptimal health cohort study: rationale, design and baseline characteristics

Background Suboptimal health status (SHS) is a physical state between health and disease, characterized by the perception of health complaints, general weakness, chronic fatigue and low energy levels. SHS is proposed by the ancient concept of traditional Chinese medicine (TCM) from the perspective of preservative, predictive and personalized (precision) medicine. We previously ...

SDF-1/CXCR7 axis regulates the proliferation, invasion, adhesion, and angiogenesis of gastric cancer cells

Background More recent studies have revealed that chemokine receptor CXCR7 plays an important role in cancer development. However, little is known about the effect of CXCR7 on the process of gastric cancer cell invasion and angiogenesis. The aim of this study is to investigate the expression of CXCR7 in gastric cancer cell lines and to evaluate the role of CXCR7 in the ...

The risk of hospitalized infection following initiation of biologic agents versus methotrexate in the treatment of juvenile idiopathic arthritis

Background In the present study, we compared the incidence of hospitalized infection among children with juvenile idiopathic arthritis (JIA) following initiation of treatment with biologic agents versus methotrexate (MTX). Methods We used national Medicaid claims data from 2000 through 2010 to create cohorts of children with JIA who were new users of tumor necrosis factor ...

Theoretical Studies of Tunable Localized Surface Plasmon Resonance of Gold-Dielectric Multilayered Nanoshells

Tunable properties of localized surface plasmon resonances (LSPR) of gold-dielectric multilayered nanoshells are studied by quasi-static theory and plasmon hybridization theory. Multilayered nanoshells with the gold core and nanoshell separated by a spacer layer exhibit strong coupling between the core and nanoshell plasmon resonance modes. It is found that the absorption spectra ...
