Актуальність. Неалкогольна жирова хвороба печінки (НАЖХП) — хронічна дифузна патологія печінки, що пов’язана з інсулінорезистентністю та метаболічними порушеннями, серед яких ожиріння, цукровий діабет 2 типу та дисліпідемія. НАЖХП охоплює простий стеатоз, який має доброякісний перебіг, неалкогольний стеатогепатит, що може прогресувати до цирозу та гепатоцелюлярної карциноми. Морфологічне дослідження печінки залишається золотим стандартом для оцінки ступеня стеатозу, печінкового запалення і фіброзу, однак все більший інтерес останнім часом викликають неінвазивні методи, серед яких оцінка різних індексів, заснованих на сироваткових маркерах. Мета. Оцінка показників діагностичної точності сироваткових маркерів та неінвазивних лабораторних індексів у визначенні морфологічних змін печінки у хворих на НАЖХП. Матеріали та методи. У дослідження включені 60 пацієнтів із НАЖХП, які проходили обстеження й лікування у відділенні захворювань печінки та підшлункової залози ДУ «Інститут гастроентерології НАМН України». Серед досліджених 26 (42,3 %) чоловіків та 34 (56,7 %) жінки, середнім віком (37,1 ± 12,4) та (44,3 ± 7,3) року відповідно. Усім пацієнтам була проведена черезшкірна пункційна трепан-біопсія печінки з подальшим морфологічним дослідженням пунктату; виконано визначення вмісту гіалуронової кислоти, a2-макроглобуліну, аполіпопротеїну А1, фібронектину, гаптоглобіну в сироватці крові, був проведений розрахунок неінвазивних маркерів фіброзу печінки: AAR, APRI, FIB-4. Результати. У хворих на НАЖХП встановлено високу діагностичну точність сироваткових маркерів фіброзу як при розмежуванні різних стадій фіброзу, так і при виключенні саме наявності фіброзу. Висновки. Визначення сироваткових маркерів має значення для вирішення питання про необхідність медикаментозного лікування та його тактику, а відповідність неінвазивних маркерів золотому стандарту — морфологічному дослідженню дозволяє уникати біопсії печінки як методу з потенційно можливими ускладненнями внаслідок своєї інвазивності.

Estudo sobre a apresentação gráfica de sinais de advertência verbais impressos em embalagens de brinquedos comercializados na cidade de São Luís (MA). Analisou-se uma amostra constituída por 612 sinais de advertência impressos em embalagens de brinquedos – representados nos modos verbal – distribuídos em 7 (sete) classificações de brinquedos. Considerou-se no estudo analítico o modelo das Variáveis da Apresentação Gráfica proposto por Mijksenaar (1997). A partir dos resultados obtidos é possível afirmar que, de maneira geral, os sinais de advertência no modo verbal não estão em conformidade com o que a literatura recomenda. Ressalta-se que, em 9 das 12 variáveis analisadas (níveis gráficos), a maioria das advertências apresentou deficiências e, estas, consequentemente, podem provocar em danos/prejuízos para o consumidor indireto, as crianças.

Authors: Elsharkasi MM , Platt JA , Cook NB , Yassen GH , Matis BA 
Published: December 2017

SUMMARY
The present study investigated the effect of three high-viscosity bulk-fill resin-based composite materials on cuspal deflection in natural teeth. Thirty-two sound maxillary premolar teeth with large slot mesio-occlusal-distal cavities were distributed into four groups (n=8). Three groups were restored with bulk-fill resin composite materials (Tetric EvoCeram Bulk Fill, Ivoclar Vivadent, Schaan, Liechtenstein; x-tra fil, VOCO, Cuxhaven, Germany; and SonicFill, Kerr, Orange, CA, USA) in a single 4-mm increment. The conventional composite group, Filtek Z100 (3M ESPE, St Paul, MN, USA), was used to restore the cavities in 2-mm increments. Cusp deflection was recorded postirradiation using a Nikon measurescope UM-2 (Nikon, Tokyo, Japan) by measuring the changes in the bucco-palatal widths of the teeth at five minutes, 24 hours, and 48 hours after completion of the restorations. Cuspal deflection was significantly higher in the conventional composite than in the Tetric EvoCeram Bulk Fill (p=0.0031), x-tra fil (p=0.0029), and SonicFill Bulk (p=0.0002) groups. There were no significant differences in cuspal deflection among the three bulk-fill materials (all p&lt;0.05). In conclusion, all the investigated bulk-fill resin composites exhibited cuspal deflection values that were smaller than those associated with a conventional incrementally placed resin composite.
A Novel Enamel and Dentin Etching Protocol Using α-hydroxy Glycolic Acid: Surface Property, Etching Pattern, and Bond Strength Studies
Authors: Cecchin D , Farina AP , Vidal CMP , Bedran-Russo AK 
Published: December 2017

SUMMARY

Objectives:
To determine the use of α-hydroxy glycolic acid (GA) as a surface pretreatment for dental restorative applications. The etching pattern of GA pretreatment of dental hard tissues was assessed by surface microhardness and scanning electron microscopy (SEM). The effectiveness of GA surface etching on the enamel and dentin resin bond strengths was assessed using two etchant application modes (rubbing and no rubbing) and three adhesive systems (Single Bond [SB], One Step Plus [OSP], and Scotchbond Universal [SBU]).

Methods:
Knoop microhardness measurements were carried out on polished enamel and dentin surfaces before and after treatment with 35% GA, 35% phosphoric acid (PA), or distilled water (control group) for 30 seconds. The microtensile bond strength test was carried out on enamel and dentin. Ultrastructural analysis of the surface and interfacial interaction was qualitatively accomplished using SEM.

Results:
Etching with either PA or GA significantly decreased the enamel microhardness, with GA being significantly less aggressive than PA (p&lt;0.001), while both acids showed similar decreases in dentin microhardness (p=0.810). SEM revealed similar etching patterns of GA and PA, while apparently a thinner hybrid layer was observed for GA groups. In dentin, the bond strengths were statistically similar between PA and GA groups, regardless of the etchant application mode (p&gt;0.05). However, rubbing of GA enhanced the bond strength to enamel. PA and GA significantly increased the SBU bond strength to enamel when compared to SB and OSP (p&lt;0.05).

Conclusions:
GA effectively etched enamel and dentin surfaces, resulting in bond strength values similar to those associated with traditional PA. GA is a suitable enamel and dentin surface etchant for adhesive restorative procedures.
Replacement of a Missing Maxillary Central Incisor Using a Direct Fiber-Reinforced Fixed Dental Prosthesis: A Case Report
Authors: Romero MF , Haddock FJ , Brackett WW 
Published: December 2017

SUMMARY
The use of the direct fiber-reinforced fixed dental prosthesis (FDP) restorative technique presented in this article will result in an ideal restoration considering both esthetics and function in a single appointment. Although indirect techniques are available and may be used, they are time-consuming, resulting in higher cost; therefore, a simplified approach combining a prebonded fiber-reinforced mesh with a sculptable micro-hybrid composite will deliver an acceptable esthetic result with proper function.

Published: December 2017

SUMMARY

Objective:
To evaluate the effect of sodium hypochlorite on the immediate and three-year bonding properties of a resin-eroded dentin interface produced by one of two adhesive strategies.

Methods and Materials:
Forty-eight molars were randomly assigned to six experimental groups, according to the combination of the adhesive strategy (etch-and-rinse and self-etch) and the dentin surface (control groups without erosion, eroded dentin surface [ED], and eroded dentin surface + NaOCl 5.2% [ED + NaOCl]). After completing restoration, specimens were stored in water (37°C) for 24 hours and then sectioned into resin–dentin beams (0.8 mm2) to be tested under tension (0.5 mm/min) immediately thereafter or after three years of water storage. To assess nanoleakage (NL), specimens were immersed in silver nitrate solution and examined by scanning electron microscopy at both time points. The dentin-etching pattern was examined under a scanning electron microscope. Data were subjected to appropriate statistical analysis (α=0.05)

Results:
In both strategies, a more pronounced and significant reduction of the microtensile bond strength (μTBS) values was observed for the ED groups (p=0.0001) after three years. However, in the ED + NaOCl group, μTBS values were maintained after three years of water storage. Furthermore, application of NaOCl to eroded dentin significantly reduced the immediate NL values and also preserved these values after three years of water storage for both adhesive strategies (p&gt;0.05). When considering the ED group, a superficial removal of the smear layer and enlarged lumen tubules in comparison to control were present. However, for ED + NaOCl, there was a total removal of the smear layer and significant numbers of collagen fibrils were exposed.

Conclusion:
The use of NaOCl may maintain the long-term stability of a resin-eroded dentin interface formed by etch-and-rinse and self-etch adhesives.

Published: December 2017

This study includes solvent extraction and electrowinning of copper from leaching process. The Taguchi method was used to determine the optimum conditions for solvent extraction process of copper ore in sulfuric acid solution. The experimental parameters of solvent extraction were: Extractant mass of sodium diethyldithiocarbamate (SDDT), agitation time, and pH value. While, the electrowinning parameters were constant at 25°C temperature, reaction voltage of 2 V, 200 A/dm2 current density, and 2.5 cm distance between electrodes. The following optimum solvent extraction parameters levels were found: Extractant mass of SDDT 100 mg, agitation time 30 min, pH = 8. Under these conditions, the extraction ratio was 97.15%. It was observed that the extraction ratio increases with the increase of SDDT mass. A contacting time of 30 min is considered for ensuring state of equilibrium, and the extraction ratio decreases in a more alkaline medium (pH >8) when the cation of hydrolysis at the aqueous phase was sufficiently disturbed from heating, allowing elements to return to the aqueous phase, thereby decreasing the extraction ratio. After electrowinning is carried out, the results for the experiments were taken to quantitative analysis using the X-ray fluorescence pectrophotometer, scanning electron microscopy, and X-ray diffraction patterns which showed the presence of pure copper at a purity level of 100%.

Correlating Diversity of Cultures and Organisation Performance in Kurdistan Region of Iraq: An Empirical Study
Authors: Tasie George O. 
Published: December 2017

The increase in globalisation has made it essential for organisations in general to deal with a cultural diverse workforce. Undoubtedly, these increases are forcing both small and large companies to recognise the importance of dealing with cultural diversity by developing new procedures and policies to guide employees. Recently, increasing workplace cultural diversity has become a significant issue for many managers of a good number of organisations in Kurdistan due to a proliferation of the presence of international businesses. The purpose of this paper, therefore, is to examine the issue that borders on diversity of cultures since research in this area is almost non- existent in Kurdistan. The paper analyses the effects of cultural diversity on performance via some randomly selected organisations in the Kurdistan Region of Iraq. The data from our findings show that there is a positive correlation between cultural diversity and organisational performance.
