Timing disparity of hepatocellular carcinoma (HCC) recurrence in a patient receiving interferon and subsequent direct antiviral agent (DAA) therapy for chronic hepatitis C

The advent of direct acting antiviral (DAA) agents has redefined the treatment landscape for hepatitis C virus (HCV) within the past decade, with achievement of high HCV eradication rates. However, several reports have suggested an increased incidence of tumor recurrence following DAA treatment compared with interferon treatment. In adding to the evolving literature, we herein present a case of a 73-year-old female with long term follow up at our center, who had recurrence of previously treated HCC after 4 years and 7 months on maintenance interferon therapy and subsequent development of a new HCC after 14 months on DAA therapy. Tumor ablation consisted of successful trans-arterial chemoembolization and microwave ablation. *Correspondence to: Hie-Won Hann, Department of Medicine, Division of Gastroenterology and Hepatology, Thomas Jefferson University Hospital, Philadelphia, PA, USA, Tel: 215-955-5806, E-mail: hie-won.hann@jefferson.edu
A Double-Crosslinked Self-Healing Antibacterial Hydrogel with Good Mechanical Performance for Wound Treatment

Self-healing hydrogel systems usually suffer from poor mechanical performance stemmed from weaker and reversible non-covalent interactions or dynamic chemical bonds, which hamper their practical applications. This issue is addressed by adopting a double-crosslinking design via employing both dynamic Schiff base bonds and non-dynamic photo-induced crosslinking. This leads to the formation of a special topological structure which simultaneously provide good self-healing capability (healing efficiency of 73.5%) and good mechanical performance (good elastic recovery and tensile modulus of 157.4 kPa, close to modulus of native skin). The quaternary ammonium and protonated amino groups can provide superior antibacterial capability, while Schiff base formation between residual aldehyde groups and amino groups on tissue surface contribute to hydrogel’s good adhesion to tissues (5.9 kPa). Furthermore, the multifunctional hydrogel with desirable mechanical performance, self-healing capability, superior antibacterial capability and good tissue adhesion can significantly promote healing of infectious cutaneous wound, tissue remodeling and regeneration.
Mobile Sentiment Analysis by Deep Learning Image Processing

Once with the growth of free data sources which makes available more data for training machine learning and deep learning algorithms, new challenges tend to appear. Usage of deep learning algorithms for solving image classification problems became one of the most popular approaches because of its flexibility and generally good results. Sentiment analysis is a problem which was previously addressed using several approaches and for a different type of data which makes it a challenging problem. This paper presents a sentiment analysis solution for images gathered on mobile devices. Our approach uses deep learning for model training and part of the system validation and a mobile (android) application for model usage and real-time image classification. We considered the possibility to perform parameters tuning in order to obtain better performance, and we present a comparison between trained models. The experiments conducted with the trained models revealed excellent performance on the mobile device with excellent accuracy real-life tests.
Comparison between isothermal and microwave gasification of lignite char for high syngas production

ABSTRACT Using the water of lignite as gasification agent, this paper mainly studies the influence of microwave and isothermal gasification on the syngas production and H2/CO ratio to obtain the maximum possible amount of high-quality syngas. The results show that microwave heating produced syngas had an immensely superior performance over conventional heating. The total gas yields of 1,000 W microwave gasification is 1.75 times more than that of the 1,000°C isothermal gasification. Moreover, the values of H2/CO ratio obtained from microwave gasification was higher than 1,000°C isothermal gasification.
Facile Synthesis, Microstructure, and Gas Sensing Properties of NdCoO3 Nanoparticles

NdCoO3 nanoparticles were successfully synthesized by a simple, inexpensive, and reproducible solution method for gas sensing applications. Cobalt nitrate, neodymium nitrate, and ethylenediamine were used as precursors and distilled water as solvent. The solvent was evaporated later by means of noncontinuous microwave radiation at 290 W. The obtained precursor powders were calcined at 200, 500, 600, and 700°C in a standard atmosphere. The oxide crystallized in an orthorhombic crystal system with space group Pnma (62) and cell parameters A, A, and A. The nanoparticles showed a diffusional growth to form a network-like structure and porous adsorption configuration. Pellets prepared from NdCoO3 were tested as gas sensors in atmospheres of carbon monoxide and propane at different temperatures. The oxide nanoparticles were clearly sensitive to changes in gas concentrations (0–300 ppm). The sensitivity increased with increasing concentration of the gases and operating temperatures (25, 100, 200, and 300°C).
The Fourth Industrial Revolution and Employment in Sub-Saharan Africa: The Role of Education

The heat of the fourth industrial revolution (4IR) in the form of automated technologies in industrial production processes is on the global world. This has raised worries regarding the potential impact of the 4IR particularly on the future of jobs in developing countries. The study investigates the impact of the 4IR on industry labor employment, with particular emphasis on the role of tertiary education in SSA from 2000 to 2018. Due to the dearth of adequate data relating to the elements of 4IR such as robotics, internet of things (IoT), and cloud technologies, the study is benchmarked on the technology achievement of SSA countries, tertiary education attainment, and some elements of Information and Communication Technologies (ICTs) like mobile phone technology and internet densities. The study employed instrumental variable regression, within the framework of the System GMM estimator, covering the 48 SSA countries. The result shows that technology achievement index (TAI), technology, mobile, mobile phone technology, and education exert a positive effect on industry labor employment in SSA. This suggests that advancement in the elements of 4IR will eventually bring about improvement in the level of industry labor employment. Based on these findings, the study recommends that the governments of SSA countries should embark on structural reforms of the educational system as well as massive investment in ICT penetration and diffusion. These efforts will produce digital manpower to fit into the new job environment while offsetting the immediate job losses occasioned by the 4IR
Effects of operational mode on particle size and number emissions from a biomass gasifier cookstove

ABSTRACT Interest in the size distribution of particles emitted from biomass cookstoves stems from the hypothesis that exposure to ultrafine particles is more detrimental to human health than exposure to accumulation mode or other size regimes. Previous studies have reported that gasifier cookstoves emit smaller particles than other cookstove designs under steady operating conditions. In the present study, the number size distribution of particles emitted from a forced-air gasifier cookstove was measured at 1 Hz as the stove transitioned between several steady and transient operating modes. During normal operation, when the stove functioned as a top-lit updraft gasifier, the distribution was bimodal, with peaks at 10 nm and 40 nm, when a pot of water was on the stove. The distribution became unimodal with a peak at 10 nm when the pot was removed. Once the fuel bed had completely gasified and the secondary flame extinguished, the concentration of particles increased and the peak in number concentration shifted to approximately 80 nm. After refueling, when the stove operated as a conventional updraft gasifier, the peak in number concentration decreased to 10 nm. When the secondary flame extinguished a second time, the peak in number concentration increased to approximately 100 nm before decreasing to 20 nm during the char burn-out phase. These results demonstrate that changes in operational mode influence the combustion process and produce distinct changes in the size distribution and rate of particle emissions.

Association between genetic variants in metabolic syndrome-related genes and risk of obstructive sleep apnea among a Chinese population

Background Despite the strong epidemiological association between Metabolic syndrome (MetS) and obstructive sleep apnea (OSA), the causal mechanism between the two remains not fully elucidated. We conducted a case-control study to evaluate the genetic association of twelve metabolic syndrome-related genes with OSA in Chinese subjects. Methods Targeted capture sequencing for twelve metabolic syndrome-related genes (EDN1, APOE, LEP, LEPR, IRS1, UCP1, ADIPOQ, PEMT, PPARG, SLC2A4, FABP2 and ADRA2A) were performed in 100 subjects including 50 patients with severe OSA and 50 non-OSA individuals. Possible associations between genetic variants and the risk of OSA were determined by logistic regression analyses. Results From the multiple genes studied, only the rs12486170 variant in PPARG gene was associated with OSA risk after adjusting for potential confounding factors. The PPARG rs12486170 AG/GG genotype was found to decrease the risk for OSA [dominant model: adjusted odds ratio (AOR) = 0.211, 95% confidence interval (CI) = 0.055-0.800, P = 0.022] compared with AA genotype. Moreover, subjects with the rs12486170 AG/GG genotype had a significantly lower apnea-hypopnea index (AHI) (median: 2.50 vs. 50.90 events/h, P = 0.019) and higher lowest oxygen saturation (LSaO2) (median: 87% vs. 75%, P = 0.040) compared with those with the AA genotype. Conclusions We identified a novel variant of PPARG in subjects with OSA, and specifically found an association between rs12486170 polymorphisms and OSA risk in a Chinese population.
From Libertarian Paternalism to Liberalism: Behavioural Science and Policy in an Age of New Technology

Behavioural science has been effectively used by policy makers in various domains, from health to savings. However, interventions that behavioural scientists typically employ to change behaviour have been at the centre of an ethical debate, given that they include elements of paternalism that have implications for people’s freedom of choice. In the present article, we argue that this ethical debate could be resolved in the future through implementation and advancement of new technologies. We propose that several technologies which are currently available and are rapidly evolving (i.e., virtual and augmented reality, social robotics, gamification, self-quantification, and behavioural informatics) have a potential to be integrated with various behavioural interventions in a non-paternalistic way. More specifically, people would decide themselves which behaviours they want to change and select the technologies they want to use for this purpose, and the role of policy makers would be to develop transparent behavioural interventions for these technologies. In that sense, behavioural science would move from libertarian paternalism to liberalism, given that people would freely choose how they want to change, and policy makers would create technological interventions that make this change possible.
Quantitative analysis and biological significance of HOXD10 and BFGF in glioma patients

Objective To investigate the expression and biological significance of gomeotic genesA13( HOXD10) and Basic fibroblast growth factor (BFGF) in gliomas. Methods 60 patients diagnosed with glioma were diagnosed in our hospital from Jan 2016 to December 2019 were chosen. The serum expression levels of S100, HOXD10 and Plexin -B2 in the experimental group (glioma patients) and the control group were measured by qRT-PCR. And the expression of HOXD10 and BFGF in different stages of glioma patients was analyzed, the relationship with the degree of tumor malignancy was analyzed. Results Compared with those of the control group, the expression levels of HOXD10 and BFGF in cerebrospinal fluid and plasma were significantly higher[blood: HOXA,13,(1.21 ± 0.14)vs 0; BFGF, (1.57 ± 0.33)vs 0 and cerebrospinal fluid: BFGF,(4.87 ± 1.13)vs 0; BFGF,(5.88 ± 0.21)vs 0]. The larger the tumor volume, the lower the degree of differentiation and the higher the expression level of HOXD10 and BFGF in the blood. The level of HOXD10 and BFGF protein in cerebrospinal fluid was significantly higher than that in plasma. Conclusion The expression of HOXD10 and BFGF in brain glioma patients is up-regulated and is significantly correlated with the degree of malignancy. The expression of HOXD10 and BFGF in cerebrospinal fluid is significantly increased and can be used as a marker of malignant degree of glioma.
DESEMPENHO ECONÔMICO E FINANCEIRO E REMUNERAÇÃO DE EXECUTIVOS EM EMPRESAS BRASILEIRAS FAMILIARES E NÃO FAMILIARES DOS SEGMENTOS CÍCLICO E NÃO CÍCLICO

Este artigo possui o objetivo de verificar a relação entre o desempenho econômico e financeiro e a remuneração concedida aos executivos nas empresas brasileiras familiares e não familiares de capital aberto pertencentes aos setores de consumo cíclico e não cíclico pela análise em amostras com predominância de empresas familiares. O procedimento metodológico empregado foi o método de análise de dados em painel com modelo econométrico de regressão múltipla, adicionado de dummy de controle familiar, por meio de dados obtidos junto à Economatica® no período de 2010 a 2015. Os resultados demonstraram que o controle, propriedade e gestão das empresas familiares têm influência negativa na remuneração concedida aos executivos da diretoria que compõem o conselho estatutário da empresa e também no desempenho econômico e financeiro para a remuneração dos executivos quando comparadas às empresas não familiares. A contribuição teórica e prática desta pesquisa é complementar a estudos anteriores que investigam a remuneração dos executivos em empresas familiares e não familiares. O que se identifica é que, por meio da Teoria da Agência, empresas familiares assumem comportamentos distintos em relação à remuneração dos executivos, assim como em relação ao desempenho econômico e financeiro para remuneração dos executivos, por incorrerem em menores custos de agência. A pesquisa contribui ao propor que a menor remuneração e o menor desempenho econômico-financeiro podem ser explicados pelo menor custo de agência e pelas características das empresas familiares, ou seja, controle centralizado na família e interesses que vão além dos aspectos econômico-financeiros: a tradição do negócio, objetivos não econômicos e em horizonte de longo prazo.
Scaffolding multilingualism in kindergarten children: A case study

This qualitative case study research entitled ‘Scaffolding multilingualism in kindergarten children: A case study’ explored how kindergarten children face learning and communication barriers when they have different home language which is not the language of instruction at school and language of others at school. In addition, it revealed how kindergarten children's language identity and cognitive investment are not allowed by the monolingually biased pedagogical approach. It has presented the scenario of scaffolding monolingual children to multilingual basing their home language as the founding scaffold ingredients. A newly admitted kindergarten girl in pre-kindergarten school was the main source of the case study including her mother and her teacher for supporting information. Interviews and notes of observation and informal communication were the research tools used for data collection. Multilingual development of the home monolingual child is the thematic issue of this study.

Investigation of model scale effects on coal pyrolysis using ReaxFF MD simulation

Abstract ReaxFF MD is a promising method for exploring complex chemical reactions, allowing large coal molecular systems simulated at high temperature. Due to the amorphous and diverse nature of coal chemical structure, model scale effect on the simulation of coal pyrolysis can be a big issue, which was investigated by comparing heat-up ReaxFF MD simulations of three Liulin coal models with 2338, 13,498 and 98,900 atoms. ReaxFF MD simulation results show its consistency in the observed trends of weight loss profiles and product generations lumped by C number for different model scales. The small-scale coal model facilitates observation of reaction sites, but can hardly access reasonable evolving trends of products and reactions. ReaxFF MD simulations of the coal model in middle scale can obtain much better evolving trends of pyrolyzates and reproduce some reaction pathways. But certain fluctuations or randomness of reactions still exist in the evolution trends of representative products. The diversity of chemical reactions in coal pyrolysis can be much more accessible by employing the large-scale coal model, thus permitting distinguishable evolving trends in pyrolyzates.
The difficulty in distinguishing the type of occlusive coronary artery disease among patients with sepsis in the emergency department: a multicenter retrospective cohort study

*Correspondence shien@url.com. tw (Chung-Hsien Chaou) Abstract Purpose: Distinguishing true obstructive coronary artery disease (OCAD) from myocardial infarction (MI) resulting from a mismatch between oxygen supply and demand (T2MI) in patients with sepsis is difficult. This study aimed to assess the clinical presentation and laboratory biomarkers of OCAD in patients with sepsis in the emergency department. Materials and Methods: This was a multicenter retrospective cohort study. We included patients diagnosed with sepsis or septic shock in the emergency department between January 2010 and December 2017 and who underwent coronary angiography in the emergency department for suspected concomitant MI. The patients were categorized into the mixedMI group, for those who had significant coronary occlusion superimposed on type 2 MI or the pure type 2 MI (T2MI) group. Results: A total of 71 patients were included after exclusion. Forty patients (56.3%) had OCAD (mixed MI). Fever (25% vs. 15%) and high scores of quick sequential organ failure assessment (qSOFA score) (35.5% vs. 27.5%) were more frequent in the T2MI group, and the troponin-I level was more elevated in the mixed MI group, but the difference was not significant. The most common focus of infection was pulmonary. Sepsis patients with OCAD tended to have longer admissions in the intensive care unit and ward admission days. However, the proportion of mortality and shock events was similar to T2MI group after percutaneous coronary artery intervention (PCI) treatment. Conclusions: Differentiating between mixed MI from pure T2MI through clinical presentation or laboratory results in patients with sepsis with suspected myocardial infarctions remains difficult. Lowering the threshold of coronary artery angiography may play a critical role in differentiating OCAD from T2MI.
