Background: The myeloid-epithelial-reproductive tyrosine kinase (MERTK) is involved in hepatic steatosis, inflammation and liver fibrosis. Here we evaluated the association between the MERTK rs4374383 single nucleotide polymorphism (SNP) and liver fibrosis progression in hepatitis C virus (HCV)-infected patients. Methods: We performed a retrospective study (repeated measures design) in 208 patients who had liver stiffness measurement (LSM), which was assessed by transient elastography No patient had cirrhosis at baseline (LSM≥12.5 kPa). Results: At baseline, 53.8% were male, the median age was 47.1 years, 13.5% reported a high intake of alcohol, 10.1% were prior injection drug users, 85.3% were infected by HCV genotype 1, and 22.6% had previously failed antiviral therapy (pegylated-interferon-alpha/ribavirin). During a median follow-up of 46.6 months, 26 patients developed cirrhosis. The rs4374383 G carriers had a higher risk of increasing LSM (adjusted arithmetic mean ratio (aAMR)=1.14; p=0.006) and a higher likelihood of having an increase in LSM greater than 5 kPa (ΔLSM≥5 kPa) [adjusted odds ratio (aOR)=2.37; p=0.029], and greater than 7 kPa (ΔLSM≥7 kPa) [aOR=3.24; p=0.032], after controlling for confounding. The SNP’s association with cirrhosis progression was close to statistical significance (aOR=2.18; p=0.070). Conclusions: MERTK rs4374383 A carriers had a lower risk of liver fibrosis progression than G carriers, supporting the hypothesis that this SNP seems to have a critical role in the pathogenesis of liver disease in HCV-infected patients.

In the process of modernization and development, a human being always needed energy, which increased the dependency on the available sources of fossil fuel. Tetraselmis, a green algal genus belong to the order Chlorodendrales, are described by their strong green coloured chloroplast, flagellated cell bodies, and the occurrence of a pyrenoid within the chloroplast. In this study, four different strains of Tetraselmis species were successfully isolated from the saltpans Kovelong, Chennai, Tamil Nadu, India. The isolated strains were cultured in the normal basal medium and their morphological features were subsequently studied. The species of Tetraselmis straiata (T. straiata) Butcher BBRR1 was confirmed using molecular identification of 18S rRNA gene analysis and its observed systematic position. Among the four different isolates, T. straiata Butcher BBRR1 recorded a highest biomass concentration of 0.58 ± 0.021 g L-1, 15% lipids, 19%  proteins and 17% carbohydrates when it grown under laboratory condition. Whereas, in open raceway ponds, T. straiata BBRR1 produced 0.95 ± 0.06 g L-1 biomass, 19%   lipids, 28%  proteins and 21%  carbohydrates in an modified CFTRI I medium. The fatty acids profile of T. straiata Butcher BBRR1showed the presence of 33.14 % Palmitic acid, 22.64% 11- Octadecenoic acid and 21.94% Heptadecanoic acid. Since T. straiata BBRR1 can be cultivated in open ponds without a major contaminations, this species can be used as novel biomass feedstock to produce biofuels. This study may suggest the potential of T. straiata BBRR1 for biofuel production and could compete the energy demand in the future. In addition, this species contains healthful components of carotenoids, lipids and proteins, all these may provide a health benefits beyond basic nutrition.

Published: October 2018

Trans platinum complexes have been the landmark in unconventional drugs prompting the development of innovative structures that might exhibit chemical and biological profiles different to cisplatin. Iodido complexes made a new turning point in the platinum drug design field since their cytotoxicity was reevaluated and reported. In this new study, we have synthesized and evaluated diodido complexes bearing aliphatic amines and pyridines in trans configuration. X-ray diffraction support the structural characterization. Their cytotoxicity has been evaluated in tumor cell lines such as SAOS-2, A375, T-47D and HCT116. Moreover, we report their solution behavior and reactivity with biological models. UVA irradiation induces an increase in their reactivity towards model nucleobase 5´-GMP in early stages, and promotes the release of the pyridine ligand (spectator ligand) at longer reaction times. Density Functional calculations have been performed and the results are compared with our previous studies with other iodido derivatives.
Measurement Invariance of a Direct Behavior Rating Multi Item Scale across Occasions
Authors: Gebhardt Markus , DeVries Jeffrey M. , Jungjohann Jana , Casale Gino , Gegenfurtner Andreas , Kuhn Jörg-Tobias
Published: October 2018

Direct Behavior Rating (DBR) as a behavioral progress monitoring tool can be designed as longitudinal assessment with only short intervals between measurement points. The reliability of these instruments has been evaluated mostly in observational studies with small samples based on generalizability theory. However, for standardized use in the pedagogical field, a larger and broader sample is required in order to assess measurement invariance between different participant groups and over time. Therefore, we constructed a DBR with multiple items to measure the occurrence of specific externalizing and internalizing student classroom behaviors on a Likert scale (1 = never to 7 = always). In a pilot study, two trained raters observed 16 primary school students and rated the student behavior over all items with a satisfactory reliability. In the main study, 108 regular primary school students, 97 regular secondary school students and 14 students in a clinical setting were rated daily over one week (five measurement points). IRT analyses confirmed the instrument’s technical adequacy, and latent growth models demonstrated the instrument’s stability over time. Further development of the instrument and study designs to implement DBRs are discussed.

The effect of innovation and technological specialization on income inequality
Authors: Yorga Permana Muhammad , Crestofel Lantu Donald , Suharto Yulianto
Published: October 2018

Using a panel of 28 European Union countries for the period 2003–2014, the authors provide empirical evidence for the relationship between innovation, technological specialization, and income inequality. The results of the fixed effect panel regressions show two important findings. Firstly, the positive link was found between innovation, as measured by patenting activities, and income inequality as measured by Gini index and the top 10% income shares of the richest. Secondly, the authors also found the positive correlation between technological specialization, as measured by the Coefficient of Variances (CV) of Revealed Technological Advantage Index, and income inequality. Overall, the study enriches the previous literature suggesting that innovation may increase the gap of income distribution through the mechanism of Skill-Biased Technical Change (SBTC) and the Schumpeterian view of entrepreneurial rent. More importantly, this study is the first which found that not only the level of innovation does matter to the income distribution, but also how the innovation activities are specialized or diversified. Concentrating the activities into few narrow sectors (i.e., increase technological specialization) may also lead to the increase of income inequality.

Published: October 2018

The article presents the results of the study of clinical efficacy of treatment of acute rhinosinusitis in 80 children aged 3–15 years using Sialor® as an adjunct to comprehensive treatment. The children of group 1 (active treatment group) received Sialor® in addition to the standard treatment without use of decongestants. group 2 (comparison group) received decongestants in addition to the standard treatment without use of Sialor®. The efficacy of treatment was assessed according to clinical examination findings. The study showed that the inclusion of Sialor® (silver proteinate) in the combined treatment improves the clinical efficacy of treatment of acute rhinosinusitis. On Day 4 after the first examination, group I showed a decrease in nasal congestion that was evaluated using Visual Analogue Scale (VAS) by more than 4 points as compared with group 2. On Day 4 of treatment, presentations of rhinorrhea in the active treatment group of children decreased by more than 2 points on VAS scale compared with the control group. The children who received Sialor also demonstrated an improvement in the quality of sleep. The results showed that the inclusion of Sialor (silver proteinate) in the treatment regimen of ARS allows to achieve a more rapid relief of symptoms of intoxication, nasal congestion, rhinorrhea, restoration of smell, improvement in the quality of sleep of patients by Day 4 from the start of treatment.

Published: October 2018

The article presents modern data on the main molecular and genetic determinants of shaping the taste preferences. The authors present the structure and mechanism of the functioning of sweet taste receptors, umami taste, acidic and bitter tastes, as well as other molecules and cellular structures influencing the perception of flavors – the gust protein, toll-like receptors. They described the role of structures ensuring perception of taste outside the oral cavity – the cells of the hypothalamus. The article underlines the importance of the genetic polymorphism of these structures and the importance of interaction of genetic factors and environmental factors in shaping the taste preferences and eating behavior of the infant. Particular attention is given to the practical significance of the presented data in the context of introduction of supplemental foods for infants.
Technique for Studying Motivation Toward Scientific Activity: Development and Practical Application
Authors: Karpov Anatolii V. , Razina Tat'yana V.
Published: October 2018

Introduction. As our analysis has shown, the literature offers very few publications that address the issue of diagnosing motives for scientific activity in adult research professionals. Being guided by the principles of the meta-system approach, we developed the concept of motivation toward scientific activity as a theoretical foundation for the appropriate diagnostic technique. According to this concept, motivation toward scientific activity includes 10 various motivational subsystems (groups of motives) such as external, internal, value, cognitive, reflexive, and indirect ones, competition-, security-, and achievement-related motives, and anti-motivation. These subsystems are reflected in the corresponding scales of the developed technique.
Methods. A total of 944 research professionals at various research institutes, including universities, and commercial scientific organizations from different cities of the Russian Federation participated in this study. Exploratory factor analysis was employed to select tasks for the technique.
Results. The final version included 70 items (7 for each of the 10 scales), of which 25,71% were ‘reverse-worded’ and 74,29% were ‘positive-worded’. The technique met the criteria of test-retest reliability (r= .899, р = .001), half-split reliability (Spearman–Brown: r= .822, p = .001; Rulon: r= .814, p = .01), and internal consistency reliability (r= .814, p≤ .05). The authors determined empirical validity of the technique by examining the relationship between scientific productivity and motivation. The Motivational Profile test by W. Richie and P. Martin was instrumental in testing construct validity. A Shapiro–Wilk test showed that the scores for each scale were normally distributed, which made it possible to use sten-score scales.
Discussion. The practice of psychological support of research activity at the RAS research institutes and R&D commercial organizations enabled authors to provide recommendations for chiefs, psychologists, and human resource managers for managing and optimizing the structure and level of motivation among research workers and increasing their labour productivity.
Toward an Ecological Perspective of Interethnic Ideologies: Moderation Effects of Ethnic Density on Relationships between Interethnic Ideologies and Intergroup Bias
Authors: Grigoryev Dmitry S. , Jurcik Tomas , Batkhina Anastasia A. , Dubrov Dmitrii I.
Published: October 2018

Introduction. In this exploratory study, we examined several interethnic ideologies held by individuals (assimilation, colorblindness, multiculturalism, and polyculturalism) from a social ecological perspective. We examined moderation effects of neighborhood ethnic density (ED) on relationships between interethnic ideologies and intergroup bias towards various minority ethnic groups in the Russian context. Intergroup bias was assessed as a composite score of bias toward four ethnic groups who have different cultural distances from the Russian mainstream population: Chechens, Belarusians, Uzbeks, and Chinese.
Method. We obtained a gender balanced sample of ethnic Russians from the Central Federal District of Russia (N = 359) comprising of 47% women and 53% men. The measures were used in a Russian translation by an adaptation using the back-translation and cognitive interviews. Multiple regression analysis was used to test the relationships.
Results. The results showed that high perceived neighborhood non-Russian ED weakened negative relations between intergroup bias and ideologies that purportedly accept cultural diversity (multiculturalism and polyculturalism). On the other hand, for interethnic ideologies those purportedly reject cultural diversity, high perceived neighborhood non-Russian ED weakened the positive relations between intergroup bias and assimilation and strengthened the negative relations between intergroup bias and colorblindness.
Summary and Conclusions. The pattern of results suggests that the relationship between attitudes and intergroup bias may change based on the perceived ethnic composition of the local area and frequency of contacts. Although our findings are relatively novel they support the emerging view that attitudes and intergroup relations need to be studied from a social ecological context.
A Study on the Effects of Multiwall Carbon Nanotubes on Dynamic Stiffness of Hydrophilic-base Magnetorheological Gel
Authors: Kim Young-Keun , Kim Jangheon , Jang Daeik , Kim Soohyun , Jung Wonsuk
Published: October 2018

Background:

Recently, addition of multi-walled-carbon-nanotubes (MWCNTs) has been
researched to enhance the rheological properties of magnetorheological (MR) materials of fluid,
elastomer and gel. However, there is a lack of study on the effects of MWCNTs on hydrophilic based
MR gels (MRG), which have shown a high potential to be applied in smart vibration control systems.

Objective:

This study is aimed to analyze the effect of MWCNTs on the dynamic stiffness of hydrophilic
based MRG.

Method:

Dynamic stiffness of hydrophilic based MRG was experimentally computed under different
magnetic fields and strain amplitudes.

Results:

Experimental results indicate that the addition of MWCNTs in hydrophilic MRG showed
overall degradation of stiffness variation in contradictory to similar research performed on silicon oil
based MR gel.

Conclusion:

These contradictory results reveal that MRGs of hydrophilic base have a different interaction
with MWCNTs than hydrophobic oil base.

Authors: Lam Sinh C. , Nguyen Kieu T.
Published: October 2018

Background & Objective:

In this work, we introduced a mathematical network model
which follows on the recommendations of 3GPP to evaluate the downlink Long Term Evolution
(LTE) network utilizing Strict Frequency Reuse (FR) scheme. The network modelling bases on the
establishment phase and communications of the FR scheme. The user average coverage probability
is derived and analysed under Rayleigh fading environment and furthermore the closed-form formulations
of the performance are found using Gauss Quadratures. Through the Monte Carlo simulation,
it is proved that the proposed analytical approach is more accurate than other approaches in the
literature.

Conclusion:

Furthermore, this paper stated that the overall system can achieve the better performance
with a higher number of Cell-Edge Users (CEUs), which contrasts with other works in the literature.
