Overexpressed C14orf166 associates with disease progression and poor prognosis in non-small-cell lung cancer
Authors: Zhou Yan-Wu , Li Rong , Duan Chao-Jun , Gao Yang , Cheng Yuan-Da , Zhang Chun-Fang
Published: August 2018

Chromosome 14 ORF 166 (C14orf166), a protein involved in the regulation of RNA transcription and translation, has been reported to possess the potency to promote tumorigenesis; however, the role of C14orf166 in non-small-cell lung cancer (NSCLC) remains unknown. The purpose of the present study was to assess C14orf166 expression and its clinical significance in NSCLC. Immunohistochemical staining, quantitative real-time PCR (qRT-PCR), and Western blotting were used to detect the C14orf166 protein and mRNA expression levels in NSCLC tissues compared with adjacent normal tissues, as well as in NSCLC cells lines compared with normal human bronchial epithelial cells (HBE). Then, the correlations between the C14orf166 expression levels and the clinicopathological features of NSCLC were analyzed. Additionally, the Cox proportional hazard model was used to evaluate the prognostic significance of C14orf166. We found that C14orf166 expression increased in carcinoma tissues compared with their adjacent normal tissues at the protein (P<0.001) and mRNA levels (P<0.001). High expression of C14orf166 was significantly associated with the T stage (P=0.006), lymph node metastasis (P=0.001), advanced TNM stage (P<0.001), and chemotherapy (P<0.001). Moreover, according to the survival analysis, patients with overexpressed C14orf166 were inclined to experience a shorter overall survival and disease-free survival time (P<0.001). Multivariate COX analysis implied that C14orf166 was an independent prognostic biomarker. Taken together, our findings indicate that the overexpression of C14orf166 may contribute to the disease progression of NSCLC, represent a novel prognostic predictor and help high-risk patients make better decisions for subsequent therapy.
Long non-coding RNA PVT1, a molecular sponge for miR-149, contributes aberrant metabolic dysfunction and inflammation in IL-1β-simulated osteoarthritic chondrocytes
Authors: Zhao Yangxue , Zhao Jiang , Guo Xufeng , She Jiang , Liu Yongjun
Published: August 2018

Osteoarthritis (OA), a common form of degenerative joint disease, is typified by inflammatory response and the loss of cartilage matrix. Long non-coding RNAs (lncRNAs) are emerging as a new player in gene regulation and exert critical roles in diverse physiologic and pathogenic processes including OA. The lncRNA plasmacytoma variant translocation 1 (PVT1) has been implicated in cancer, diabetes and septic acute kidney injury. Recent research confirmed the elevation of PVT1 in patients with OA. However, its role in the development of OA remains poorly elucidated. In the present study, high expression of PVT1 was observed in cartilage of OA patients and IL-1β-stimulated chondrocytes. Moreover, cessation of PVT1 expression dramatically reversed the inhibition of IL-1β on collagen II and aggrecan expression, but suppressed IL-1β-induced elevation of matrix metalloproteinases (MMPs), including MMP-3, MMP-9 and MMP-13. Simultaneously, PVT1 inhibition also antagonized the production of inflammatory cytokines upon IL-1β stimulation, including prostaglandin E2 (PGE2), NO, IL-6, IL-8 and TNF-α. Further molecular mechanism analysis identified PVT1 as an endogenous sponge RNA that could directly bind to miR-149 and repress its expression and activity. More importantly, miR-149 inhibition reversed the protective roles of PVT1 cessation in attenuating IL-1β-evoked matrix aberrant catabolism and inflammation. Together, this research confirms that lowering PVT1 expression may ameliorate the progression of OA by alleviating cartilage imbalance toward catabolism and inflammatory response, thus supporting a promising therapeutic strategy against OA.

Authors: Chen Yuan , Wang Liang , Geng Jiang-hui , Zhang Hui-feng , Guo Li
Published: August 2018

The current study was designed to investigate effect of copper administration on oxidative damage to the brain in ApoE−/− mice and to explore the putative neuroprotective effects rendered by apolipoprotein E (ApoE). Male C57BL/6 ApoE−/− and wild-type mice were randomly assigned into four groups, ApoE−/− mice wild-type mice treated with either copper or saline. Copper sulphate pentahydrate or saline (200 µl) were administered intragastrically daily for 12 weeks. Expression of malondialdehyde, superoxide dismutase (SOD), hemeoxygenase 1 (HO-1), and NAD(P)H: quinone oxidoreductase 1 (NQO1) were determined by a combination of biochemical assays. The concentration of copper in the brain of C57BL/6 mice and ApoE−/− mice treated by copper significantly increased compared with mice treated by saline (P=0.0099 and P=0.0443). Compared with the C57BL/6 mice treated by copper, the level of the ApoE−/− mice treated by copper was higher (P=0.018). TBARS and SOD activities or the expressions of NQO1 and HO-1 in the brain were not significantly different amongst the four experimental groups of mice. The relative value of NQO1/β-actin expression in the brain of the ApoE−/− mice was similar in both saline and copper administration experimental groups. However, Western blot analysis showed that NQO1 expression was significantly higher in the ApoE−/− mice brain treated with saline compared with saline treated wild-type mice (P=0.0449). ApoE does not function in protecting the brain from oxidative damage resulting from copper build-up in Wilson’s disease, but may play a role in regulating copper accumulation in the brain.

Authors: Yao Shun , Li Jian , Fan XiuDe , Liu QingQuan , Lian JianQi
Published: August 2018

To explore the effect of selective serotonin re-uptake inhibitors (SSRIs) on risk of type II diabetes mellitus (T2DM) and acute pancreatitis (AP), expecting to provide guidance for clinic. Literature was retrieved by searching Pubmed, Embase, Cochrane and Scopus and hand searching of reference lists of related articles. Stata 14.0 was utilized for processing and analysis, and adjusted odds ratios (aORs) were applied. Our study included 113898 T2DM patients and 284131 controls from nine studies and 17548 AP patients and 108108 controls from four studies. The pooled aORs of SSRIs on the risk of T2DM and AP were 1.38 (95% confidence interval (CI) = 1.24–1.54) and 1.26 (95% CI = 1.13–1.40), respectively. Study design, quality, ethnicity, follow-up, and sample size of patients were the resources of heterogeneity. Subgroup analysis showed that 2 weeks is a high-risk time for AP after SSRIs use, with 1.48-fold-times as much after it. This meta-analysis provides evidence of a significant positive association between SSRIs use and risks of T2DM or AP, and duration of 2 weeks of SSRIs use has higher risk of AP, which should be paid much attention to.
ZNF139 increases multidrug resistance in gastric cancer cells by inhibiting miR-185
Authors: Tan Bibo , Li Yong , Zhao Qun , Fan Liqiao , Wang Dong
Published: August 2018

It has been reported that the expression of zinc finger protein 139 (ZNF139) and microRNA-185 (miR-185) were associated with proliferation, drug resistance of gastric cancer (GC) cells. However, the detailed mechanisms have not been fully investigated. The expression of ZNF139 in both GC tissues and cell lines was tested, then SGC7901/ADR or SGC7901 cells were transfected with ZNF139-siRNA, miR-185 analog, or pcDNA-ZNF139. Cell activity was determined by MTT assay. Real-time PCR and Western blot were utilized to detect ZNF139, miR-185, and multidrug resistance (MDR) related genes including MDR1/P-gp, GST-π, MRP-1, Bcl-2, TS and Bax. ChIP and dual luciferase activity assay were used to investigate regulation between ZNF139 and miR-185. Increased ZNF139 and decreased miR-185 expression were detected in GC tissues and cell lines. Transfection with ZNF139-siRNA into SGC7901/ADR cells markedly increased expression of miR-185, and treating with chemotherapeutic drugs ADR, 5-FU, L-OHP, the survival rate of SGC7901/ADR cells obviously decreased after ZNF139-siRNA transfection. On the other hand, transfection with pcDNA-ZNF139 in GC cell line SGC7901 resulted in an increased expression level of ZNF139 and a decline in the expression level of miR-185, meanwhile drug resistance of GC cells was clearly enhanced to ADR, 5-FU, L-OHP. Dual luciferase activity assay demonstrated that ZNF139 inhibited transcriptional activities of miR-185’s promoter in cells transfected with the reporter plasmid encompassing the upstream promoter region of miR-185 along with pcDNA-ZNF139. Our data reveal that ZNF139 might promote MDR gene MDR1/P-gp, MRP-1 and Bcl-2 by prohibiting miR-185.

Authors: Hoang Minh Vu Nguyen , Pham A. Tuan , Nguyen L. D. Luan , Diep V. Thanh
Published: August 2018

Land pooling and readjustment (LPR) is a significant instrument which is used to the rapid development of urbanization. It is a way of urban expansion and renovation without any compulsory revoking of land. By this way, people should not be relocated like in other ordinary planning projects, but they are encouraged to contribute their land (or land value) for construction and modernization of infrastructure system. Therefore, after contribution, remaining land will increase its value, and living conditions will also be improved. Especially, this approach is effectively implemented in urban renovation projects in various countries and regions worldwide, i.e. Japan, Germany, Korea, Taiwan, The United States of America, Australia, India, and Thailand. Its effectiveness has been demonstrated for mitigating unusual urban growth in peripheral areas. This study aims to perform the significances of LPR instrument, as well as demonstrate its practical impacts by analyzing an implemented case-study of Tra Vinh city. Recommendation of deployment is also done as a solution for renovation of landscapes of Ho Chi Minh City (HCMC) embankments.
Proposed probabilistic models of pipe failure in water distribution system
Authors: Pham Thi Minh Lanh , Pham Hai Ha , Do Nguyen Anh Thu , Le Dinh Hong
Published: August 2018

All pipes in water supply network are installed underground, so it is difficult to identify pipe failure location during the operation of a system. Prediction of the risk of pipe failure in the water distribution systems is necessary for preparation of reparations and displacement of a pipe network system. Based on the probability of pipe failure, it will be possible to save money and labor cost for water supply companies. Many studies have been conducted on this topic, some of which used experimental models, others used statistical models in which recently many authors used regression model, but almost all the models come up with calculating the pipe failure rate per unit length of pipe in a year. It is not a direct probability of pipe failure. This article reviews various methods to evaluate pipe failure in water distribution systems. Based on that, the authors proposed two models: Regression Logistic Model and Decision Tree Model that would support an effective decision making for detecting the pipe failure and proposing appropriate solutions.

Authors: Truong Quang Thanh , Le Phan Ta , Nguyen Thi Nhu Quynh
Published: August 2018

Most of the earth embankments in central Vietnam are usually built with clays. Some types of clays in this area are swollen. If they are used to build dams, it can be detrimental to the embankment. Based on the results of laboratory test analysis, the authors investigated swelling characteristics of some soil types in the study area and found that the swelling rate of soil increases with the compaction of the soil sample. When swelling under pressure in approaching water over time, the swelling coefficient of the soil decreases significantly. Thus, swelling clays can be used to make dams, but they must be put in the appropriate position for the purpose of not swelling freely.

Published: August 2018

The article identifies and postulates the importance of energy efficiency issues providing certain principles for the sustainable development of society, the national and world economy. The study analyzed the most energy-intensive types of economic activity - industrial production, which has a significant potential for energy conservation and energy efficiency from all energy consumers. The main indicator in the analysis of energy costs in industry is the structure of the costs of production and the energy balance for the respective types of production. The revealed regularities testify the availability of significant reserves of energy conservation and energy efficiency, which is available in certain types of industrial production: the manufacturing industry, the extraction of useful minerals, and the production and distribution of electricity, gas and water. The reduction in energy costs should concern not only technical, but also organizational changes. These recommendations are aimed at increasing the competitiveness of Russian products by reducing the material costs of energy. The most successful way to cope with the task of energy saving and increasing the energy efficiency of an industrial enterprise is the use of modern management mechanisms, including the international energy management standard ISO-50001.

Authors: Zhadanovsky Boris , Sinenko Sergey , Slavin Alexey
Published: August 2018

The characteristics of wall panels, the facing element of which is porous concrete, are given. For exterior wall panels, laboratory suggested the exposed porous concrete of grades B7,5 and B10 based on white and grey cements M400. As aggregates, one uses limestone and granite mined in the corresponding quarry. Air-entangling additives are applied in concrete manufacturing, due to which placeability of concrete mix is improved and volumetric weight of concrete is reduced. In its turn, it allowed reducing water absorption and enhancing freeze resistance of products. Presence of fine-splitted air in formation of closed pores (pore forming) improves the structure of exposed concrete, bringing its properties closer to the ones of porous claydite-concrete as the essential material of exterior wall panel.

Nonlinear design model of reinforced concrete in terms of triaxial deformation
Authors: Berlinov Mikhail , Grigorjan Artem
Published: August 2018

The influence of reinforcement in the concrete work in the conditions of triaxial stress state high-rise construction is considered. The basic phenomenological resolving equations in a triaxial stress-strain state under vibration effects were developed for the calculation of reinforced concrete elements working with and without cracks in terms of nonlinearity and rheology of concrete deformation. A method for linearizing a problem based on integral estimates is proposed, which provides for the fixation of the creep processes in the considered period of time. The implementation of this method will allow us to find a numerical solution of the problem. Such an approach in the design of reinforced concrete structures will allow not only more fully taking into account the real conditions of their work, revealing additional reserves of load capacity, but also opening additional opportunities for analysis and forecasting their functioning at various stages of operation.
About the influence of hardening conditions on the structure and properties of expansive concretes
Authors: Alekseev Vyacheslav , Harchenko Igor , Harchenko Aleksey , Bazhenova Sofia
Published: August 2018

The paper describes the effect of hardening conditions on the hydration of cement stone and methods of controlling the concrete formation on the basis of the above research methodology. It has been proved that when the humidity of the medium in which hardening takes place is regulated, the strength and the deformation of the material change. By adding an expand-ing component to concrete, it is possible to adjust the technical parameters of concrete and simulate the durability of concrete structures. Thus, the study of the mechanisms of volumetric deformation during hardening of cement stone with a different ratio of the expanding additive allows designing con-crete compositions for different operating conditions.

Polyurethane foams are currently the most effective thermal insulation materials, polyisocyanurates have low combustibility. Predicting the number of closed cells forming a gas-filled matrix in the finished polymer is necessary to improve the quality and durability of rigid sprayed polyurethane foam (SPF) and also be able to determine their quantity in finished coatings using standardized techniques. Depending on the number of closed cells, the polyurethane coatings are classified into certain levels in European documents. The methods of determining the volume percentage of open and closed cells of polyurethane foam, the problems of applying these methods, measuring equipment and their errors are analyzed in the article. The authors analyzed the international standard ISO 4590 for determining the volume percentage of open and closed cells spread in the EU countries and the American standard ASTM D 6226 for the purposes of harmonization of European standards with the developed national standard for PUR insulation and polyisocyanurate (PIR), sprayed on the site of production.
Bending strength and phase composition of cement stone subjected to loading at an early stage
Authors: Galkin Yuriy , Udodov Sergey
Published: August 2018

The article deals with the results of comparative tests of the phase composition of cement stone distinguished by strength under bending and compression. The comparison has been made between samples subjected to early loading and control samples. An increase in tensile strength in bending of samples subjected to early loading was recorded. The difference in compressive strengths does not exceed 5%. X-ray phase analysis indicates amorphous phase increase with the growth of strength properties, which is manifested in increased intensity of the amorphous phase arc in the X-ray diffraction pattern. The highest peak of the curve corresponds to the maximum flexural strength of the entire row of samples. Among the samples subjected to early loading, the peak intensity of the group of crystal tobermorites with interplanar distances 11.5-11.3Å and 12.5Å appeared to be higher than the intensity of the control samples. It was proposed that the amorphous structure affects the increase in tensile strength in bending of cement stone subjected to early loading.

Effective binder based on the artificial anhydrite for manufacturing of filling mixtures
Authors: Galtseva Nadezda , Bogdanova Anfisa
Published: August 2018

The article exposes the results of research on the development of filling mixtures based on artificial anhydrite obtained after the interaction of concentrated sulfuric acid and limestone flour. The anhydrite derivation method has a significant impact on its properties and brings more options for the application. The key features of artificial anhydrite are high compressive strength which is more than 50 MPa and extended setting time which is more than 10 hours. In order to use it as a binder in the filling mixtures, it is necessary to modify properties of the anhydrite by integrating the hardening activators. In the relation to the study it was found that the optimal activator providing desirable setting start time (at least 2 hours) and a sufficient set of strength in the first 7 days of hardening is a mixture of 5% portland cement CEM I 42,5 and 1% of potassium sulfate, where 100% is the mass of binder. The additional inclusion of Melment F10 plasticizer in the amount of 0.4 to 1% of the binder ensures the achievement of the such parameters as the 0.3 water-binder ratio, setting start from 120 to 225 min, final setting time from 180 to 355 min, compressive strength after 24 hours from 6.9 to 13.3 MPa, after 7 days from 24.0 to 33.5 MPa. The microstructure of the binder has been analyzed and the modification options of the artificial anhydrite have been revealed in order to regulate its technical and technological properties., Two compounds of the filling mixture have been developed on the basis of the obtained binder, technical properties of compounds satisfy the maximum requirements for filling materials for depleted underground spaces. Research results have shown an opportunity and a prospectively of integrating the modified artificial anhydrite in structures of filling mixtures.
Neural network principle of implementation of digital filters
Authors: Morozov Sergey , Makarov Gennady , Kuzmin Konstantin
Published: August 2018

Comparative evaluations of the frequency responses (FR) of two types of filters implemented by the classical and neural network methods are carried out. It is shown that the neural network principle of the implementation of digital filters can serve as an alternative to the classical method for specifically defined parameters of FR in the pass bands and attenuation bands of the frequencies of signal spectrum. The simplest method for calculating the parameters of the filters’ difference equations is the neural network approach, regardless of the type of classification of discrete and digital filters. The implementation of TM (transmultiplexer) on a digital element base requires the use of methods of filtering, modulating and demodulating signals that are largely different from traditional analog methods. The frequency responses of non-recursive types of filters presented in the paper are based on the property of the approximable function determined only in the pass bands and attenuation bands of the frequencies of signal spectrum.

Phenomenology method of making a place
Authors: Tran Duc
Published: August 2018

The paper shows the concept of phenomenology originated from Edmund Husserl’s contemplation of “I think, therefore I am.” As the scientific method of consciousness, phenomenology relates to architecture via the phenomenological-self. The method concentrated on investigation and description, without prejudices. Living in the world, the phenomenological-self can be a being man, a perpetual man, a wandering man, or a sensory man. Places appear because these egos have projected them to in-between the Earth and Heaven. The selves rendered their dwelling by reflection, imagination, apperception, or sensation of the built environment. The site historicity impacted on making architecture as humans’ embodiment. The influence can be either site conformation or humans force as traditional culture. Both are the primary objects of the phenomenology method that is taken shape in four steps, from Husserl’s five phases for pure knowledge. Applying those paces in making a place, designer and students keep off their prejudices to produce a pure phenomenological architecture meaningful and articulatory to its surrounding.
