AbstractBackground:Primary hyperparathyroidism (pHPT) is associated with low-grade inflammation, left ventricular hypertrophy and increased cardiovascular mortality, but the association between inflammatory markers and parameters of adverse cardiac remodeling is unknown. We investigated the relationship between C-reactive protein (CRP), the essential amino acid tryptophan and its pro-inflammatory derivatives kynurenine and quinolinic acid (QUIN) with echocardiographic parameters.Methods:Cross-sectional baseline data from the “Eplerenone in Primary Hyperparathyroidism” trial were analyzed. Patients with any acute illness were excluded. We assessed associations between CRP, serum levels of tryptophan, kynurenine and QUIN and left ventricular mass index (LVMI), left atrial volume index (LAVI) and E/e′.Results:Among 136 subjects with pHPT (79% females), 100 (73%) had arterial hypertension and the prevalence of left ventricular hypertrophy was 52%. Multivariate linear regression analyses with LVMI, LAVI and E/e′ as respective dependent variables, and C-reactive protein and tryptophan, kynurenine and QUIN as respective independent variables were performed. Analyses were adjusted for age, sex, blood pressure, parathyroid hormone, calcium and other cardiovascular risk factors. LVMI was independently associated with CRP (adjusted β-coefficient=0.193, p=0.030) and QUIN (β=0.270, p=0.007), but not kynurenine. LAVI was related with CRP (β=0.315, p<0.001), kynurenine (β=0.256, p=0.005) and QUIN (β=0.213, p=0.044). E/e′ was related with kynurenine (β=0.221, p=0.022) and QUIN (β=0.292, p=0.006). Tryptophan was not associated with any of the remodeling parameters.[Correction added after online publication (22 April 2017: The sentence “Among 136 subjects with pHPT (79% females), 100 (73%) had left ventricular hypertrophy.” was corrected to “Among 136 subjects with pHPT (79% females), 100 (73%) had arterial hypertension and the prevalence of left ventricular hypertrophy was 52%.”]Conclusions:Cardiac remodeling is common in pHPT and is associated with low-grade inflammation and activation of the tryptophan-kynurenine pathway. The potential role of kynurenine and QUIN as cardiovascular risk factors may be further investigated in future studies.

Published: April 2017

AbstractBackground:Thiamine has a crucial role in energy production, and consequently thiamine deficiency (TD) has been associated with cardiac failure, neurological disorders, oxidative stress (lactic acidosis and sepsis) and refeeding syndrome (RFS). This review aims to explore analytical methodologies of thiamine compound quantification and highlight similarities, variances and limitations of current techniques and how they may be relevant to patients.Content:An electronic search of Medline, PubMed and Embase databases for original articles published in peer-reviewed journals was conducted. MethodsNow was used to search for published analytical methods of thiamine compounds. Keywords for all databases included “thiamine and its phosphate esters”, “thiamine methodology” and terms related to critical illness. Enquiries were also made to six external quality assurance (EQA) programme organisations for the inclusion of thiamine measurement.Summary:A total of 777 published articles were identified; 122 were included in this review. The most common published method is HPLC with florescence detection. Two of the six EQA organisations include a thiamine measurement programme, both measuring only whole-blood thiamine pyrophosphate (TPP). No standard measurement procedure for thiamine compound quantification was identified.Outlook:Overall, there is an absence of standardisation in measurement methodologies for thiamine in clinical care. Consequently, multiple variations in method practises are prohibiting the comparison of study results as they are not traceable to any higher order reference. Traceability of certified reference materials and reference measurement procedures is needed to provide an anchor to create the link between studies and help bring consensus on the clinical importance of thiamine.

Abstract

Purpose
This study investigated the prevalence of Internet addiction (IA) and cyberbullying and examined profiles of adolescents with increased risk to develop pathological behaviors.

Methods
In this cross-sectional, school-based study, 8053 students of 30 middle and 21 high schools (12–18 years old) were invited to participate, based on a multistage stratified random sampling technique. The Internet aiddiction test (IAT) was used along with information on socio-demographics, Internet activities and cyberbullying experience.

Results
Five thousand five hundred and ninety students participated (response rate 69.4%). Pathological Internet use (IAT ≥50) was found in 526 (10.1%), while 403 (7.3%) experienced cyberbullying as victims and 367 (6.6%) as perpetrators during the last year. In multivariable models, the odds of IA increased with online hours on mobile phones and Internet use during weekends, Internet café visits, chatrooms usage and engagement in cyberbullying. Cyberbullying victims were more likely to be older, female, Facebook and chatrooms users, while perpetrators were more likely to be male, older Internet users and fans of pornographic sites. A perpetrator was significantly more likely to have also been a victim [odds ratio (OR) = 5.51, confidence interval (CI): 3.92–7.74]. Hours of daily Internet use on a mobile phone was independently associated with IA and cyberbullying (OR) 1.41, 95% CI 1.30, 1.53 and OR 1.11, 95% CI 1.01, 1.21, respectively.

Conclusions
Cyberbullying is associated with IA and the hours spent online on a mobile phone affected both conditions. The increasing Internet access through mobile phones or other devices should be accompanied by the appropriate education of both parents and adolescents on safe Internet use.

Authors: Zhang Shuang , Zhang Long 
Published: April 2017

Abstract
In this paper, 2,5-furandicarboxylic acid (FDCA) was efficiently prepared by the direct oxidation of 5-hydroxymethylfurfural (5-HMF) using hydrogen peroxide (H2O2) in alkaline conditions without any catalysts. The effects of reaction parameters on the process were systematically investigated and the optimal parameters were obtained as follows: molar ratio of 5-HMF:KOH:H2O2 was 1:4:8, reaction temperature and reaction time were determined as 70°C and 15 minutes, respectively. Under these conditions, the yield of FDCA was 55.6% and the purity of FDCA could reach 99%. Moreover, we have speculated the detailed oxidation mechanism of 5-HMF assisted by hydrogen peroxide in alkaline condition to synthesize FDCA.

Published: April 2017

AbstractThe adsorption and the inhibitive properties of methanol extract of Euphorbia heterophylla on copper in 0.5 M HNO3have been studied by weight loss method at different temperatures (30-50°C), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) techniques. Also, the surface morphology was analyzed by scanning electron microscopy (SEM). It was found that the inhibition efficiency increases with increasing extract doses and decreased with increasing temperature. The polarization data revealed that this extract acts as mixed type inhibitor. The adsorption process was more favored at lower temperatures with larger negative standard free energy. The extract was adsorbed physically on the copper surface followed Frumkin isotherm.

Published: April 2017

Abstract
In this paper, the removal of benzotriazole (BTA) was investigated by a Photo-Fenton process using nano zero valent iron (NZVI) and optimization by response surface methodology based on Box-Behnken method. Effect of operating parameters affecting removal efficiency such as H2O2, NZVI, and BTA concentrations as well as pH was studied. All the experiments were performed in the presence of ultraviolet radiation. Predicted levels and BTA removal were found to be in good agreement with the experimental levels (R2 = 0. 9500). The optimal parameters were determined at 60 min reaction time, 15 mg L-1 BTA, 0.10 g L-1 NZVI, and 1.5 mmol L-1 H2O2 for Photo-Fenton-like reaction. NZVI was characterized using X-ray diffraction (XRD), transmission electron microscope (TEM) images, and scanning electron microscope (SEM) analysis.

Authors: Heimowska Aleksandra , Morawska Magda , Bocho-Janiszewska Anita 
Published: April 2017

Abstract
The environmental degradation of poly(ε-caprolactone)[PCL] in natural fresh water (pond) and in The Baltic Sea is presented in this paper. The characteristic parameters of both environments were measured during experiment and their influence on the biodegradation of the samples was discussed. The loss of weight and changes of surface morphology of polymer samples were tested during the period of incubation. The poly(ε-caprolactone) was more biodegradable in natural sea water than in pond. PCL samples were completely assimilated over the period of six weeks incubation in The Baltic Sea water, but after forty two weeks incubation in natural fresh water the polymer weight loss was about 39%. The results have confirmed that the investigated polymers are susceptible to an enzymatic attack of microorganisms, but their activity depends on environments.

Published: April 2017

Abstract
The aim of this paper is to localize the fugitive leaks from the above ground facilities of the existing system of Titas Gas (TG) after developing mathematical model for fugitive emission. Soap screening techniques and Gasurveyor 500 series instrument were used in this study for detecting potential leaks. Leaked gas was quantified using either Hi-Flow gas sampler or bagging measurements system. The results show that the respective potential gas leaking point of City Gate Station (CGS), commercial Regulating and Metering Station (RMS), industrial RMS, residential RMS and Town Bordering Station (TBS)/ District Regulating Station (DRS) are scrubber dump valve (average leak rate 217.00 L/min), insulating point (average leak rate 4.04 L/min), tube fitting connector (average leak rate 8.00 L/min), connector (average leak rate 1.55 L/min) and pressure relief valve (average leak rate 437.92 L/min). Fugitive methane emission can be reduced by stopping leaks of fittings or components having high KLeak value.

Abstract
Our research aims to identify the importance of anthropometry measurements and functional testing of two groups that practice sport different, the first group, the experimental group was formed by 25 students (age 10 ± 2.1 years, 13 boys and 12 girls), that practiced 2 hours a week physical education and other 2 hours a week basketball and volleyball optional courses; and the second group formed by 25 students (age 10 ± 1.8 years, 14 boys and 11 girls), that practiced 2 hours a week classic physical education.
The anthropometric tests included in the research were the measurement of height, weight, different length of superior and inferior segments, bust, spread of arms, biacromial diameter, bitrohanterian diameter and chest perimeter.
Results showed that children from the experimental group, that practiced more sports activities, developed more quickly and had better proportionality index then the sample group. Statistically significant differences were determined within the experimental group both in the initial and in the final tests (p<0.05), also significant differences were discovered between the experimental and the sample group in the final measurement (p<0.05).
Conclusions of this research showed that more physical activities can influence the development of children both in anthropometric way and in functional and health related.

Published: April 2017

Abstract

Background
The aim of our study was to obtain reference data of the EORTC QLQ-C30 quality of life dimensions for the general Slovenian population. We intend to provide the researchers and clinicians in our country with the expected mean health-related quality of life (HRQL) scores for distinctive socio-demographic population groups.

Methods
The EORTC QLQ-C30 questionnaire supplemented by a socio-demographic inquiry was mailed or distributed to 1,685 randomly selected individuals in the Slovenian population aged 18 – 90. Answers from 1,231 subjects representing socio-demographic diversity of the Slovenian population were collected and transformed into EORTC dimensions and symptoms. The impact of socio-demographic features on HRQL scores was assessed by multiple linear regression models.

Results
Gender, age and self-rated social class are the important confounders in the quality of life scores in our population. Men reported better quality of life on the majority of the specific scales and, at the same time, reported fewer symptoms. There was no gender-specific difference in cognitive functioning. The mean scores were consistently lower with age in both sexes.

Conclusions
This is the first study to report the normative EORTC QLQ-C30 scores for one of the south-eastern European populations. The reported expected mean scores allow Slovenian oncologists to estimate what the quality of life in cancer patients would be, had they not been ill. As they are derived by common methodology, our results can easily be included in any further international comparisons or in the calculation of European summarized HRQL scores.
Socio-Economic Convergence as a Necessary Precondition and Determinant of Societal Growth
Authors: Hudec Martin 
Published: April 2017

Abstract
The issue of socio-economic convergence is nowadays more than ever an extremely dominant topic, especially in the case of less developed countries and countries suffering stagnation, mainly due to the integration processes occurring worldwide and the determinant to achieve long-term growth in an effort to advance towards the socioeconomic sustainable level of developed economies. A key assumption towards convergence is that economies with initially lower socio-economic levels will at some point reach (in an idea case) or get very close the level of developed economies, gradually reducing the gap between the capital stock and the level of product size between countries, while the lower economic level the country has, the higher the growth rate it will go through the transition period. This suggests that the economies with lower levels of performance will grow on average at a higher rate than economies that are more efficient. It is therefore expected that the growth performance of a country will with its improvement also at some point slow down and quite realistically there can also occur a situation where the levels of development and growth of individual states economies will rather show delay. This is basically an opposite action to the concept of convergence, which is known as the divergence. The aim of our research paper is to analyze closely the concept of convergence, while pointing it is specifically characteristics and overall focusing on the significance of the issue of convergence.
Reproductive Potentials of Diploid and Polyploidy Representatives of the Genus Сobitis (Cypriniformes, Cobitidae)
Authors: Mezhzherin S. V. , Salyy T. V. , Tsyba A. A. 
Published: April 2017

Abstract
Comparison of reproductive parameters in several Cobitis forms with different ploidy shows that the maximum fertility is found in diploid Cobitis, the triploids are less fertile and the tetraploids even less fecund. The latter reach maximum values of size and weight indicators but minimum number of eggs, the smallest size of the ovaries but the biggest eggs. Nevertheless, the combined reproductive potential of polyploid females is higher than of diploid spiny loaches with equal ratios of males to females in populations. The obvious reasons for the successful expansion of polyploid individuals of the spiny loaches are both their higher fertility at the population level and the changes in environmental conditions associated with the regulation of all major rivers in Ukraine in the 1960-1970s.
Hibernation of Parti-Coloured Bat, Vespertilio murinus (Chiroptera, Vespertilionidae), in Belarus
Authors: Shpak A. V. 
Published: April 2017

Abstract
Parti-coloured bat (Vespertilio murinus Linnaeus, 1758) was considered in Belarus as a migrant species until recently. This point of view was based on the absence of winter records as well as the registrations in Austria and Romania of two V. murinus′ specimens, banded in Belarus. The data, obtained over the past few years, allow to state, that the whole territory of Belarus belongs to the winter range of this species. Hibernating animals were observed exclusively in the anthropogenic roosts.
Preparation of magnesium oxide and magnesium silicate replicas retaining the hierarchical structure of pine wood
Authors: Klaithong Somruedee , Van Opdenbosch Daniel , Zollfrank Cordt , Plank Johann 
Published: April 2017

Abstract
Replicas retaining the structural characteristics of softwood (Pinus sylvestris) were obtained by infiltrating pretreated templates with a methanolic methoxymagnesium methyl carbonate (MeOMgOCO2Me) solution as a precursor which then hydrolyzed into MgCO3 nanoparticles. Subsequent calcination at temperatures ranging from 500 to 1450°C yielded annealed MgO replicas on levels of hierarchy from the macroscopic to the submicron scale. The mechanical stability of the replicas could be improved through calcination at 1450°C. However, this treatment leads to considerable shrinkage (Δax=56%). Even more stable MgO replicas were obtained by infiltrating the pine template first with MeOMgOCO2Me, followed by a second infiltration step with an ethanolic tetraethyl orthosilicate (TEOS) solution and subsequent calcination at 1350°C. The resulting replicas constitute an MgO framework overgrown with Mg2SiO4 (forsterite) and exhibit compression strengths of 31±8 MPa, as well as hierarchical structures combined with an anisotropic porosity.
