Subclinical Diastolic Dysfunction in Diabetic Population
Authors: Mitrovska Slavica 
Published: November 2017

Abstract
Introduction. Left ventricular dysfunction is very frequent in asymptomatic diabetic population. Tissue Doppler Imaging (TDI) is a new echocardiographic technique, able to record early changes of left ventricular dysfunction and to identify asymptomatic diabetic patients at high risk of developing heart failure.
Aim. To assess the role of TDI in early detection of diastolic dysfunction in asymptomatic diabetic patients.
Methods. Cross-sectional study that involved a total number of 48 subjects. The target group consisted of 25 asymptomatic diabetic patients and control group was composed of 23 subjects without diabetes. All subjects underwent echocardiography (conventional 2D and Pulsed-Wave Doppler and contemporary-TDI) to analyze left ventricular function. We compared the results from both echo-techniques and analyzed the relation of echo-cardiographic parameters with risk factors.
Results. We found statistically significant difference between TDI and PW Doppler (E/E'vs E/A) in target (Z=−3.17, p<0.001) and control group (Z=−2.4, p<0.003). There was no significant difference in E/A between the groups (Z=0.0, p<1.0). TDI identified significantly lower E' (Z= 2.03, p<0.04) and higher E/E' (Z= −2.12, p<0.03) in target vs control group.
LVDD strongly correlated with duration of DM (p<0.00001), age (p<0.00001), female gender (p<0.0001) and obesity indices (BMI, BSA) (p<0.00001, p<0.00001) in both groups.
Conclusion. TDI unmasks the presence of subclinical LV dysfunction in asymptomatic diabetic patients and has a valuable prognostic importance.

Abstract
Introduction. As a N-methyl-D-aspartate receptors antagonist, magnesium may play a role in prevention of pain. The aim of this study was to assess the effects of single dose magnesium sulfate preoperatively on postoperative pain scores, discomfort and quality of sleep.
Methods. Forty patients scheduled for elective laparoscopic cholecystectomy were randomized in two groups. Group A received 20 mg/kg magnesium sulfate after the anesthesia induction, prior to surgical incision, and Group B was the control group. Assessment was made for pain at rest in both groups according to VAS (0-10), analgesic consumption, discomfort and quality of sleep during first 48 hours postoperatively.
Resultѕ. Compared to control group, magnesium-treated patients had lower postoperative pain at rest according to VAS score (p< 0.05) and consumed less analgesic drugs during the first 48 hours (p<0.05). The magnesium-treated group experienced less discomfort during the first and the second postoperative day. The magnesium-treated group reported no changes in sleeping pattern compared to preoperative sleeping pattern, while the control group showed an increase in insomnia during the first and the second postoperative night, compared to that preoperatively.
Conclusion. Perioperative use of magnesium sulfate as an adjuvant to general anesthesia is associated with lower postoperative pain, less analgesic consumption, less discomfort and better sleep in the postoperative period.
Annealing and Ni content effects on EPR and structural properties of Zn1–xNixO aerogel nanoparticles
Authors: Sayari A. , El Mir L. 
Published: November 2017

AbstractZn1-xNixO aerogel nanopowders with nickel concentration in the range of 0.05 ≤ x ≤ 0.25, were synthesized by the sol-gel processing technique and post-annealed in air at 500 °C. Structural, vibrational, thermal and magnetic properties of the as-prepared and annealed Zn1-xNixO powdered samples were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman scattering, thermal gravimetric analysis (TGA) and electron paramagnetic resonance (EPR) spectroscopy. In addition to the ZnNiO phase, XRD analysis revealed the formation of a secondary NiO phase when the Ni content was greater than or equal to 10 %. The TEM images confirm that the particle size is in the range of 20 nm to 40 nm, in accordance with XRD results, and the particles are well dispersed. Raman scattering measurements confirm the wurtzite structure of the synthesized Zn1-xNixO nanopowders and show that intrinsic host-lattice defects are activated when Ni2+ions are substituted to the Zn sites. Room temperature ferromagnetic order was observed in all of the samples and was strongly dependent on the Ni content and thermal annealing. These results indicate that the observed room temperature ferromagnetism in ZnNiO may be attributed to the substitutional incorporation of Ni at Zn sites.

Published: November 2017

AbstractZinc oxide thin films with different thicknesses were prepared on microscopic glass slides by sol-gel spin coating method, then hydrothermal process was applied to produce zinc oxide nanorod arrays. The nanorod thin films were characterized by various spectroscopic methods of analysis. From the images of field emission scanning electron microscope (FESEM), it was observed that for the film thickness up to 200 nm the formed nanorods with wurtzite hexagonal structure were uniformly distributed over the entire surface substrate. From X-ray diffraction analysis it was revealed that the thin films had good polycrystalline nature with highly preferred c-axis orientation along (0 0 2) plane. The optical characterization done by UV-Vis spectrometer showed that all the films had high transparency of 83 % to 96 % in the visible region and sharp cut off at ultraviolet region of electromagnetic spectrum. The band gap of the films decreased as their thickness increased. Energy dispersive X-ray spectroscopy (EDS) showed the presence of zinc and oxygen elements in the films and Fourier transform infrared spectroscopy (FT-IR) revealed the chemical composition of ZnO in the film.

Some Remarks on Language Usage in Late Babylonian Letters
Authors: Schmidl Martina 
Published: November 2017

AbstractThis paper deals with language usage in private and institutional letters from the Neo-Babylonian and Achaemenid periods. It analyses the usage of terms of address, greeting formulae and direct and indirect phrasing, drawing on notions of politeness developed by Brown and Levinson. Of particular interest are questions of usage within a temple hierarchy and its implications for professional relationships. For private letters, the case for the appellation of ‘lord’ for women as previously claimed by the author is further substantiated.
Dēnkard III Language Variation and the Defence of Socio-Religious Identity in the Context of Early-Islamic Iran
Authors: Terribili Gianfilippo 
Published: November 2017

AbstractThe aim of the present paper is to illustrate as a case study, the linguistic and stylistic peculiarities characterizing the third book of the Dēnkard, one of the most authoritative texts in Zoroastrian Pahlavi literature (9th-10th CE). The analysis will consider these features as part of a coherent system, styled to serve the dialectic strategies pursued by the Zoroastrian high priests in response to the pressures their own community was facing in the early Islamic period. In order to provide a more comprehensive overview on DkIII language distinctiveness, the research will underline the outward/inward dynamics, addressing both the relation of this theological dialectic with the surrounding socio-cultural environment and the leadingrole claims of a group within a politically subordinated community

Authors: Karagul Osman , Nalcakan Gulbin Rudarli , Dogru Yeliz , Tas Murat 
Published: November 2017

Abstract
Introduction. The aim of the study was to examine the effect of circadian rhythm on dynamic balance performance and to determine the role of physical activity level, body temperature, chronotype, and gender in this possible effect. Material and
methods. Forty-two young male and female subjects with different physical activity levels participated in the study. A dynamic equilibrium test, a Star Excursion Balance Test (SEBT), was conducted at 9:00, 13:00, and 17:00 on three different days with at least two days of interval between tests. The test scores were calculated by dividing the reaching distances by the leg length and multiplying the quotient by 100. The physical activity level and sleep state were evaluated using questionnaires. Before each test, body temperatures were measured orally. Results. The best SEBT scores were found at 13:00 and 17:00 in the male group and in the trained group. The body temperature changes increased parallel to SEBT scores. The scores for the non-dominant leg were found to be significantly different in posterior test directions, and those for the dominant leg were different in anterior directions. Chronotype did not affect the test results. Conclusions. Circadian rhythm was found to have an effect on dynamic balance performance. Body temperature, gender, and physical activity level were also found to play a role in this effect.

Abstract

Background
It is hypothesized that metabolism plays a strong role in cancer cell regulation. We have recently demonstrated improved progression-free survival in patients with glioblastoma who received metformin as an antidiabetic substance during chemoradiation. Although metformin is well-established in clinical use the influence of metformin in glioblastoma is far from being understood especially in combination with other treatment modalities such as radiation and temozolomide.

Materials and Methods
In this study, we examined the influence of metformin in combinations with radiation and temozolomide on cell survival (clonogenic survival), cell cycle (routine flow cytometric analysis, FACScan), and phosphorylated Adenosine-5’-monophosphate-activated protein kinase (AMPK) (Phopho-AMPKalpha1 - ELISA) levels in glioblastoma cell lines LN18 and LN229.

Results
Metformin and temozolomide enhanced the effectiveness of photon irradiation in glioblastoma cells. Cell toxicity was more pronounced in O6-methylguanine DNA methyltransferase (MGMT) promoter non-methylated LN18 cells. Induction of a G2/M phase cell cycle block through metformin and combined treatments was observed up to 72 h. These findings were associated with elevated levels of activated AMPK levels in LN229 cells but not in LN18 cells after irradiation, metformin, and temozolomide treatment.

Conclusions
Radiosensitizing effects of metformin on glioblastoma cells treated with irradiation and temozolomide in vitro coincided with G2/M arrest and changes in pAMPK levels.
Antifungal properties of essential oils for improvement of indoor air quality: a review
Authors: Whiley Harriet , Gaskin Sharyn , Schroder Tiffany , Ross Kirstin 
Published: November 2017

Abstract
Concerns regarding indoor air quality, particularly the presence of fungi and moulds, are increasing. The potential for essential oils to reduce, control or remove fungi, is gaining interest as they are seen as a “natural” alternative to synthetic chemical fungicides. This review examines published research on essential oils as a method of fungal control in indoor environments. It was difficult to compare the relative performances of essential oils due to differences in research methods and reporting languages. In addition, there are limited studies that scale up laboratory results and assess the efficacy of essential oils within building environments. However, generally, there appears to be some evidence to support the essential oils clove oil, tea tree oil, oregano, thyme and lemon as potential antifungal agents. Essential oils from heartwood, marjoram, cinnamon, lemon basil, caraway, bay tree, fir, peppermint, pine, cedar leaf and manuka were identified in at least one study as having antifungal potential. Future studies should focus on comparing the effectiveness of these essential oils against a large number of fungal isolates from indoor environments. Studies will then need to focus on translating these results into realistic application methods, in actual buildings, and assess the potential for long-term antifungal persistence.
Macrophage activation syndrome associated with systemic lupus erythematosus treated successfully with the combination of steroid pulse, immunoglobulin and tacrolimus
Authors: Aoyama-Maeda Natsuki , Horino Taro , Ichii Osamu , Terada Yoshio 
Published: November 2017

Abstract
Macrophage activation syndrome (MAS), a variant of secondary hemophagocyticlymphohistiocytosis, is a potentially life-threatening complication of inflammatory and autoimmune diseases. We present a case of MAS as a rare manifestation of systemic lupus erythematosus. Although initial treatment with corticosteroid, with or without cyclosporine A, is justified in patients with MAS, evidence regarding the effectiveness of this treatment protocol remains to be clarified. Our patient was successfully treated with a combination of intravenous immunoglobulin therapy and intravenous methyl predonisolone pulse therapy, which was followed by a course of oral prednisolone and oral tacrolimus. Based on our experience, we propose tacrolimus to provide a more useful adjuvant treatment to corticosteroid therapy than cyclosporine A.

Published: November 2017

Abstract
In recent times political events started to exert more and more significant impact on national financial systems due to sharpening of political problems in various countries. Undoubtedly, their influence can be followed in price dynamics of stocks which are trading in the securities market. The need to understand political news impact on the market as a whole and its separate industries is faced by investors and market agents for proper orientation in market environment. Since this issue provides rather controversial results in different studies, the authors set the aim to investigate the Russian market with the use of GARCH models. Such approach allowed determining precisely the political events’ influence on return and volatility of market assets as well as leverage and clusterization effects. The obtained results may be beneficial for investors, operating in the Russian stock market, other market agents and specialists in the field of financial science.
An Analysis Regarding Cash Holdings. Empirical Study on the Bucharest Stock Exchange Listed Firms

Published: November 2017

Abstract
Worldwide corporate cash holdings have significantly increased and have become an important tool for managers. This study explores the factors that influence firms’ behavior regarding cash holdings and the signal that financial conservatism is sending to potential investors. Our data consists in annual observations collected through the Reuters Eikon platform. It includes companies listed on the Bucharest Stock Exchange, the investigated period being 2005-2014. The econometric analysis employs multivariate regression for an unbalanced panel data, using the OLS technique. The results show a positive correlation of cash holdings with the value registered by this indicator in the previous period, fact that might be interpreted as an attempting of the companies to maintain a target level of cash. Also, the results showed a non-linear relationship between leverage and cash holdings, while the tangible assets determine a negative correlation. As regards firm size and ownership concentration, the correlations were not statistically validated.
Perceived Organizational Support, Stress Coping Behaviors and Mediating Role of Psychological Capital: Special Education and Rehabilitation Centers

Published: November 2017

Abstract
High level stress in work place is known to be associated with negative organizational behaviors and bad organizational performance. There are individual and organizational factors influencing stress coping behavior of employees. In this study we explore the impact of employees’ perceptions of organizational support on their stress coping capabilities (problem-focused stress coping and emotion-focused stress coping) and whether their psychological capital (PsyCap) plays a mediating role in this relationship using the sample of employees in special education and rehabilitation centers in Turkey. Multivariate statistical analyses show a significant positive relationship between perceived organizational support (POS) and problem-focused stress coping (PFSC), and no significant relationship between POS and emotion-focused stress coping (EFSC). A significant positive association is detected between POS and PsyCap. Accordingly, our findings show that PsyCap plays a partial mediating role in the association between POS and PFSC.
Peirce’s “Ideas, stray or stolen, about scientific writing” and the relationship between methodeutic, speculative rhetoric, and the universal art of rhetoric
Authors: Gava Gabriele 
Published: November 2017

Abstract
This paper is a reading of Peirce’s manuscript “Ideas, stray or stolen, about scientific writing.” The latter text has been considered to be a key for understanding the relationship between speculative rhetoric and methodeutic. While I agree that it includes essential reflections on the third branch of Peirce’s logic, I will argue that the classification of rhetoric studies that it contains cannot be used to clarify the way in which methodeutic and speculative rhetoric are related to one another. I will first introduce the classification as it is presented by Peirce in “Ideas, stray or stolen, about scientific writing” and list some problems that immediately arise when we identify methodeutic with the rhetoric of science. Then, I will elucidate Peirce’s distinction between the universal art of rhetoric, speculative rhetoric, and ordinary rhetoric. I will argue that the classification of rhetoric studies in “Ideas, stray or stolen, about scientific writing” should be seen as a classification of the ways in which we can obtain different ordinary rhetorics specifying the contents of speculative rhetoric for different contexts of sign use. To finish, I will propose a different approach to support the claim that methodeutic is a subdivision of speculative rhetoric.
Nuclear Markers (AFLPs) and Chloroplast Microsatellites Differ Between Fagus sylvatica and F. orientalis
Authors: Gailing O. , Wuehlisch G. Von 
Published: November 2017

AbstractFormer studies based on chloroplast markers and allozymes suggested that postglacial recolonization of central Europe by Fagus sylvatica L. occurred from one or a few undifferentiated refuges. Here, we examine F. sylvatica from Germany and Greece and different provenances of F. sylvatica ssp. orientalis (Lipsky) Greut & Burd. (F. orientalis Lipsky) with chloroplast microsatellites and AFLP markers. Only such AFLP markers were selected that had shown a differential amplification in F. sylvatica and F. orientalis in a preliminary analysis. UPGMA cluster analysis of AFLP data distinguished one F. sylvatica group and one F. orientalis group from northern Turkey. Low structuring in the neighborjoining analysis and the lack of diagnostic bands for either taxon suggests a relatively recent differentiation in Fagus orientalis and F. sylvatica. High bootstrap values were only found for a separate cluster that comprises F. orientalis from two different forest botanical gardens. Four of these samples have a unique chloroplast type and are genetically very similar (bootstrap value 96) mostly likely due to clonal replication. Only two different chloroplast types (type 1 in Germany, type 1 and type 2 in Greece) could be detected for F. sylvatica. In contrast, F. orientalis from northern Turkey showed different chloroplast types even within one provenance pointing to a glacial refuge in northern Turkey and a bottleneck at the time of postglacial recolonization of central Europe. The classification of ten samples from northern Turkey as F. sylvatica by AFLP data, chloroplast markers and morphology questions the interpretation of F. orientalis and F. sylvatica as two geographically separated (allopatric) taxa.
Simple PCR Markers for the Study of Chloroplast in Eucalyptus
Authors: Soto A. 
Published: November 2017

Summary
Combined use of two newly designed PCR primers with already described rpl2 and trnH primers, yields amplification of three non-independent products from the hypervariable JLA region of eucalypt chloroplast. Polymorphism analysis of the resulting PCR markers is proved to be a time- and cost-efficient alternative to traditional cpDNA techniques as RFLP or sequencing for Eucalyptus globulus Labill. population genetics studies.
