Published: December 2016

AbstractA cluster analysis is applied to the Aerosol Robotic Network (AERONET) data obtained at Belsk, Poland, as well as three nearby Central European stations (Leipzig, Minsk and Moldova) for estimation of atmospheric aerosol types. Absorption Ångstrom exponent (AAE), aerosol optical thickness (AOT) and extinction Ångstrom exponent (EAE) parameters are used. Clustering in both 2D (AOT, EAE) and 3D (AOT, EAE, AAE) is investigated. A method of air mass backward trajectory analysis is then proposed, with the receptor site at Belsk, to determine possible source regions for each cluster. Four dominant aerosol source regions are identified. The biomass burning aerosol source is localized in the vicinity of Belarusian-Ukrainian border. Slovakia and northern Hungary are found to be the source of urban/industrial pollutants. Western Poland and eastern Germany are the main sources of polluted continental aerosols. The most differentiated source region of Scandinavia, Baltic Sea and Northern Atlantic, associated with lowest values of AOT, corresponds to clean continental and possibly maritime type aerosols.

Published: December 2016

SummaryIn recent years, results obtained from different studies with large cohorts have revealed a bond between the presence of extensive lymphocytic infiltration and favourable prognostic associations in the early-stage of breast cancer (BC) and high response rates to neoadjuvant chemotherapy. Examiners used tumors from large cohorts of patients who took part in randomized neoadjuvant and adjuvant clinical trials. The importance of tumor infiltrating lymphocytes (TILs) appears to be subtype-specific and varies depending on the histological characteristics of the tumor. TILs have proven to be a good prognostic marker, but only in highly proliferative breast tumors such as triple negative breast tumors (TNBC) or HER 2 positive BC.In the era when standard, well-known, prognostic and predictive biomarkers are ever changing and the use of molecular profiling analyses are increasing, we are looking for techniques to improve our understanding of tumor biology and improve patient outcome. The relevance of TILs cannot be ignored but needs to be properly evaluated in larger prospective studies which must encompass the parameters set out in previous studies. The use of TILs as prognostic biomarkers in early breast cancer may represent a new dawn, and use of immunotherapy, especially immune checkpoint inhibitors, probably is the future for the breast cancer but it is not yet ready for prime time.

Published: December 2016

AbstractStatins are drugs that are well tolerated, but considering their extensive use, there are still concerns regarding their safety. Knowledge of patients about the side effects of statins has not been adequately studied, although timely recognition of the AES is of vital importance for improving the quality of patient care and reducing morbidity and suffering. The aim of this study was to develop and test a questionnaire for measuring the knowledge of patients about statin therapy about adverse effects of statins (AES).This two-center cross-sectional study was conducted during the period from March 1, 2015 to April 1, 2016, taking place in pharmacies from the city of Belgrade and at the Department of Internal Medicine, Clinical Center in Kragujevac, Serbia. The study included 300 patients and 20 pharmacists.The questionnaire showed satisfactory internal consistency, with Cronbach’s alpha of 0.898, good construction and homogeneity of questions. After splitting the questionnaire to two parts at random, Cronbach’s alphas were 0.834 and 0.842 for the both parts, respectively. Exploratory factorial analysis revealed two domains. The patients rated their knowledge of the side effects of statins 52.7±19.9 on the visual analogue scale.Based on the results of this study, we believe that this questionnaire could be a useful tool for testing the knowledge of patients about adverse effects of statins and help physicians to identify patients with insufficient knowledge who should be additionally informed about it.

AbstractThe aim of this study was to investigate the possible potential of preschool staff through a newly designed questionnaire and evaluate their role in the prevention of early childhood caries (EEC) in Serbia where extremely high prevalence of this preventable disease was recorded.We preformed a cross-sectional study of 268 preschool staff using specially prepared semi-structured questionnaire for measuring potential of secondary children’s caregivers to prevent EEC. The questionnaire was tested on a pilot sample and after that all collected data were analyzed trough construction of correlation matrix with the evaluation of the value of each question, reliability testing, factorial analysis and estimating of its validity using SPSS software.The tested questionnaire had good internal consistency based on the Cronbach’s alpha coefficient value of 0.873 calculated directly and similar value (0.899) after applied Spearman-Brown “prediction” formula. Using exploratory factorial analysis and orthogonal rotation, we identified two domains that emerged with similar loadings (4.043 and 3.183). The first factor (domain) reflected attitudes of the study participants towards prevention of EEC, and the second factor (domain) showed behaviour of the study participants, which includes preventive actions against EEC.The total score of the questionnaire was correlated positively with oral health knowledge (Spearman’s correlation coefficient 0.331, p=000) and inversely with the length of employment, where each additional year of employment decreased the total score of the questionnaire by 1.20.These findings could partially explain an extremely high prevalence of EEC in young children and indicate that preschool teachers should be more engaged in health education activities and motivation programs.
Morphological Variation of Fissure and Lobe of the Left Lung: A Case Report
Authors: Dogood Atoni Atoni , Aidemise Oyinbo Charles , Patrick Udoye Ezenwa 
Published: December 2016

Abstract
The left lung usually has an oblique fissure that divides it into superior and inferior lobes. Some variants in the lobar fissure are well known, but the knowledge of certain uncommon variants will enhance our anatomical understanding and proper identification of the bronchopulmonary segments. Several imaging techniques have been used to describe anatomical variations of the lung, but studies that utilize dissections as tools for understanding lobar variations were limited. In this report, we described an incomplete horizontal fissure, bifurcated accessory fissure, incomplete superior and middle lobes, and fibrous condensation of the left lung pulmonary pleura observed during dissection. The knowledge of these anatomical variations will be useful in surgical segmental resection and lobectomy, and for accurate interpretations of medical diagnostic images.

Published: December 2016

Abstract
Breast involvement by lymphoma is uncommon and poses challenges in diagnosis. Breast involvement by malignant lymphoma, whether primary or secondary, is a rare event. Primary breast lymphomas account for 0.38% - 0.7% of all non-Hodgkin lymphomas, 1.7%-2.2% of all extranodal non-Hodgkin lymphomas, and only 0.04% - 0.5% of all breast cancer cases. Most frequent primary breast lymphomas are diffuse large B cell lymphomas (53%). Breast mucosa-associated lymphoid tissue (MALT) lymphomas account for a small fraction of all the MALT lymphomas (1% - 2%). Herein we report a case of a patient with primary breast MALT lymphoma and its presentation on different imaging modalities. Two years after the presentation and treatment with eight cycles of chemotherapy, the patient is alive and well, without evidence of residual disease or recurrence.

Abstract
The aim of the study was to evaluate genotoxic effects of Pirimor-50®, a pirimicarb-based formulation (50 % active ingredient), in human lymphocyte cultures and Vicia faba root meristems. Furthermore, the objective was to examine a combined influence of insecticide treatment with mammalian microsomal S9 and vegetal S10 metabolic fractions or S10 mix metabolic transformation extracts (after Vicia faba primary roots treatment with Pirimor-50®). We used sister chromatid exchange assay-SCE and measured cell cycle progression and proliferation (proportion of M1-M3 metaphases and replication index ratio-RI). Two processes were used for plant promutagen activation: in vivo activation-Pirimor-50® was applied for 4 h to the plant and then S10 mix was added to lymphocytes; and, in vitro activation-lymphocytes were treated with Pirimor-50® and S10 or S9 for 2 h. Direct treatment induced significantly higher SCE frequencies in meristems at 0.01 mg mL-1. In lymphocytes, significantly higher SCE was at 1 mg mL-1 with decrease in RI and M1-M3 metaphase proportions at 0.5 mg mL-1 and cell division stop at 2.5 mg mL1. S10 mix lymphocyte treatment showed significantly elevated SCE values at 2-2.5 mg mL-1, with cell death at 3 mg mL-1. Lymphocyte treatment with Pirimor-50® together with S9 or S10 showed slightly elevated SCE frequency but had a significant influence on RI decrease, with lowest values in S9 treatment. Since no data are available on the genotoxicity of Pirimor-50®, this study is one of the first to evaluate and compare its direct effect in two bioassays, animal and vegetal, and also the effect of plant and animal metabolism on its genotoxic potential.

AbstractThe present study was aimed at the estimation of heavy metal content in vegetables sold at the city market of one of the densely populated Croatian cities, Varaždin, and to establish the relationship between their levels and possible sources of contamination. Twenty-eight samples of the most common diet vegetables (red and white potato, onion, carrot, common bean, lettuce, and cabbage) were randomly bought at the market in September and October 2013. Using the atomic absorption spectrometry method, concentrations of nine heavy metals (As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn) were measured in the selected samples. The results showed that, in five out of 28 samples analysed, six concentrations exceeded the maximum levels provided for in the regulations: five for Pb and one for Cd. Maximum regulated levels for Pb were exceeded in two samples of red potato, two samples of common bean, and one sample of carrot (17.9 %), and for Cd in a sample of red potato (3.6 %). In conclusion, the cause of the overstepping of the maximum levels for Pb and Cd in the vegetables analysed was most likely the contaminated soil. The possible sources of soil contamination include traffic, nearby industry, floodwaters of rivers and streams, and the use of pesticides and fertilisers in agricultural production.

Surface Layer Properties of Low-Alloy High-Speed Steel after Grinding
Authors: Jaworski Jan , Trzepieciński Tomasz 
Published: December 2016

Abstract
Investigations of the surface layer characteristics of selected kinds of low-alloy high-speed steel after grinding were carried out. They were carried out on the flat-surface grinder with a 95A24K grinding wheel without cooling. The influence of grinding parameters was defined especially for: the quantity of secondary austenite, surface roughness, microhardness and grinding efficiency with a large range of grinding parameters: grinding depth 0.005–0.035 mm, lengthwise feed 2–6 m/min, without a cross-feed on the whole width of the sample. It was found that improvement of grinding properties of low-alloy high-speed steels is possible by efficient selection of their chemical composition. The value of the grinding efficiency is conditioned by grinding forces, whose value has an impact on the grinding temperature. To ensure high quality of the tool surface layer (i.e. a smaller amount of secondary austenite, lack of wheel burn and micro-cracks) in the case of sharpening of tools made of low-alloy high-speed steel, the grinding temperature should be as low as possible.

Some conclusions are derived from the parametric study into the influence of frustum angle and wall thickness upon the energy absorption capability.
On the Numerical Solution of the Initial-Boundary Value Problem with Neumann Condition for the Wave Equation by the Use of the Laguerre Transform and Boundary Elements Method
Authors: Litynskyy Svyatoslav , Muzychuk Yuriy , Muzychuk Anatoliy 
Published: December 2016

AbstractWe consider a numerical solution of the initial-boundary value problem for the homogeneous wave equation with the Neumann condition using the retarded double layer potential. For solving an equivalent time-dependent integral equation we combine the Laguerre transform (LT) in the time domain with the boundary elements method. After LT we obtain a sequence of boundary integral equations with the same integral operator and functions in right-hand side which are determined recurrently. An error analysis for the numerical solution in accordance with the parameter of boundary discretization is performed. The proposed approach is demonstrated on the numerical solution of the model problem in unbounded three-dimensional spatial domain.
A Study of the Preload Force in Metal-Elastomer Torsion Springs
Authors: Sikora Wojciech , Michalczyk Krzysztof , Machniewicz Tomasz 
Published: December 2016

Abstract
Neidhart type suspension units composed of metal-elastomer torsion springs can be a good alternative to steel helical springs in applications such as vibration absorbers or vehicle suspension systems. Assembling this type of spring requires initial preload of the elastomeric working elements, which determines their operating properties. The results of experimental tests and numerical simulations concerning the preload of elastomeric working elements in Neidhart type suspension units are presented in the paper. The performed research made it possible to propose a new calculation model for determining the preload force value acting on the elastomeric cylindrical elements applied in this type of suspension unit. The results obtained using the proposed model exhibit good convergence with FEM simulation results within the range of the tested geometrical and material properties.

Characteristics of Pneumatic Tuners of Torsional Oscillation as a Result of Patent Activity
Authors: Homišin Jaroslav 
Published: December 2016

Abstract
Mechanical systems with combustion engines, compressors, pumps and fans, can be characterized as torsional oscillating mechanical systems (TOMS). It is therefore necessary to control their dangerous torsional vibrations. It was confirmed that dangerous torsional vibration can be reduced to acceptable level by an appropriate adjustment, respectively by tuning the TOMS. According to several authors, the most appropriate way of system tuning is application of suitable flexible element, which is flexible shaft coupling. It turned out that one of the types of shaft couplings, which are particularly suited to meeting this objective are pneumatic flexible shaft couplings, to act as so-called pneumatic tuners of torsional oscillations. The issue of research and development of pneumatic tuners of torsional oscillations, among other things is, long-term in the focus of the author. The existence of tuners creates the opportunity to develop new ways of tuning torsional oscillating mechanical systems. The author of the scientific article will focus on the characteristics of developed pneumatic tuners of torsional oscillation in terms of their design, construction, function, significance advantages and conditions imposed on pneumatic tuners based on the results of his patent activity. Simultaneously provides information about the characteristic properties of pneumatic tuners of torsional oscillations in the general design.
