Abstract
Experimental models have strongly contributed to the comprehension of the processes of peritoneal damage that take place during peritoneal dialysis treatment in human patients. A variety of peritoneal dialysis models have been developed, mostly using rats and rabbits.
In this study we present the successful development of a custom-made improvised peritoneal catheter for an experimental non-uremic rabbit model of peritoneal dialysis.
A detailed description of the surgical technique of peritoneal catheter implantation, care and removal is provided.
This innovative approach to constructing a peritoneal catheter in rabbit animal model of peritoneal dialysis is easy, reproducible and inexpensive. The surgical technique applied provided adequate tissue samples for both light and electron microscopy.

Abstract
The aim of this study was to investigate the etiology of subclinical mastitis (SCM) in dairy Jersey cows with the use of bacteriological and molecular identification methods. In the study 121 Jersey and 78 hybrid Jersey cows with SCM were observed in the Samsun district of Turkey. A total of 411 California mastitis test (CMT) positive milk samples from these animals were examined bacteriologically. The prevalence of subclinical mastitis was 54.75% and 67.2% in Jerseys and hybrids, respectively. On bacteriological examination, a total of 92 strains were isolated from 411 milk samples. The most prevalent bacteria were Staphylococcus spp. (69.56%). Among them 24 isolates were Staphylococcus aureus (26.08%) the other isolates were Streptococcus dysgalactiae (23.91%), Enterococcus spp. (3.26%) and Streptococcus agalactiae (3.26%). All strains were identified with bacteriological culture methods, as well as by Polymerase Chain Reaction (PCR). Gram-negative bacteria were not isolated. In conclusion, the etiology of SCM in full blood and hybrid Jersey dairy cows in Samsun and the prevalence of bacteria were determined. The relatively high prevalence of SCM indicates the potential need for the consideration of some factors contributing to the formation of mastitis (e.g. management) as well as bacterial agents. The present study and further studies may be useful to develop mastitis vaccines by means of providing true vaccine strain sources.

Abstract

Salmonella enterica serotype Enteritidis is an important alimentary pathogen that recently gained special attention due to the ability of a large number of strains to form biofilms. Qualitative testing of biofilm forming ability was performed by observing the morphotype of the colonies on Congo Red agar and by conducting the pellicle test, while quantitative testing was carried out by Cristal violet assay on microtiter plates. A total of 14 isolates of S. Enteritidis were tested for biofilm forming ability, while Salmonella Enteritidis ATTC 13076 was used as the reference strain. Based on the morphotype of colonies cultivated on Congo Red agar at 25°C incubation temperature, among tested isolates three morphotypes were detected – red, dry and rough (rdar), brown, dry and rough (bdar) and smooth and white (saw). Half of the tested isolates demonstrated rdar morphotype. All isolates that showed a specific morphotype at this incubation temperature also formed the corresponding type of pellicle at the air-liquid interface. Additionally, comparing OD (optical density) values obtained by crystal violet test between groups of isolates that represent one of the three detected morphotypes (rdar, bdar and saw), statistically significant differences were detected. Based on OD values obtained by crystal violet test at both applied incubation temperatures, isolates were classified into three categories, regarding their ability to form biofilms: strong, moderate and weak biofilm producers. By comparing the amounts of the biofilms formed after 48h at 25°C and 37°C, statistically significant differences were noted (P<0.05). In this research we presented micrographs and a reconstruction of three-dimensional projections of biofilm developing phases of rdar morphotype isolates, which were obtained using confocal laser scanning microscopy.

Abstract
The aim of this study was to evaluate the effects of 60 days of rose-hip and grapeseed dietary supplementation of a balanced home-cooked diet on serum oxidative stress parameters: ROMs, MDA and FRAP in army service dogs before and after regular physical exercise. The dogs were fed a balanced cooked diet as instructed by army standards until the initial blood sampling in June. Thereon the dogs were randomly allotted to 4 groups according to the dietary regime: dogs maintained on a balanced cooked diet according to army standards, branded dry dog food, cooked diet with added 500 mg rose-hip extract, and cooked diet with added 100 mg grapeseed extract for a 60 day period from June to September after which all 4 groups were fed the standard cooked meal diet. Sampling was performed at the beginning of the experiment (June), 60 days from the start of the treatment (September) and finally 60 days after the end of supplementation (November). Statistical analysis of the results included descriptive statistical parameters: mean (M), standard deviation (SD), and variation coefficient (CV%). In order to test the statistical significance of the differences between treatments a multifactor variance test (ANOVA) was performed for ROM, MDA and FRAP and the combined effects of diet, exercise and time period were observed. The initial (in June) increase in MDA and ROMs after exercise indicates the presence of oxidative stress 30 minutes after exercise. However, the antioxidative effects of rose-hip and grapeseed extracts are not conclusive, as multifactor ANOVA testing of time, diet, and exercise factors did not reveal for MDA statistically significant differences either at 60 days of supplementation nor 60 days after withdrawal of the supplements. Only one distinct exception was recorded for the prolonged antioxidative effects reflected in significantly decreased (p<0.01) ROMs before and after exercise in dogs fed the branded dry food 60 days after the end of such dietary regime (November). FRAP values tend to be higher (p>0.05) after exercise compared to before exercise in all experimental groups in November, indicating on a possible redistribution and upregulation of endogenous antioxidants during the experiment.

Abstract
The objective of this study was to assess cell-free fermented culture broth of 9 Lactobacillus plantarum strains as antibiotic alternatives for the inhibition of in vitro growth of enterotoxigenic Escherichia coli (ETEC) and Shiga toxin-producing E. coli (STEC) isolated from postweaning pigs with colibacillosis and edema disease in 2014. A total of 10 ETEC and 5 STEC strains isolated from postweaning pigs were tested in antimicrobial susceptibility tests. ETEC and STEC strains used in this study possessed at least one of fimbrial, enterotoxin, and Shiga-toxin genes when tested by polymerase chain reaction. Among 9 L. plantarum strains tested, 3 strains (Lp 2-05, 2-06, and 1-03) showed inhibitory activity of in vitro growth against 10 ETEC strains (100%) and 7 strains (Lp 6-13, 3-06, 3-05, 7-01, 2-06, 1-03, and 6-05) showed inhibitory activity of in vitro growth against 5 STEC strains (100%). Three strains (Lp 3-05, 2-06, and 1-03) showed inhibitory activity of in vitro growth against 10 ETEC (100%) and 5 STEC (100%) strains. The results of this study show the inhibitory activity of cell-free fermented culture broth of L. plantarum against ETEC and STEC isolated from postweaning pigs with colibacillosis and edema disease.

Abstract
Rhabdomyosarcoma is a malignant tumor of the skeletal muscles that is occasionally observed in free-living and pet birds. A case of malignant rhabdomyosarcoma in the musculature of the right wing of a captive female cockatiel (Nymphicus hollandicus) was investigated. The clinical aspect and radiographic images suggested an invasive neoplasm. Histologically, the tumor was composed of a patternless array of large primitive polygonal cells or sheets of bizarre cells with giant nuclei and atypical mitoses set in a collagenous stroma. Anaplastic cells were poorly differentiated and exhibited notable cellular and nuclear pleomorphism. Nuclei showed extreme variability in number, size, shape, chromatin distribution and nucleolar size and number. The cross striations were encountered in elongated multinucleated cells known as “strap cells” and in ovoid cells known as “racquet cells” and numerous mitotic figures were also observed. Neoplastic cells were positive for muscle actin and negative for desmin, suggesting the diagnosis of anaplastic rhabdomyosarcoma. It is the first reliable record of a rhabdomyosarcoma in a cockatiel (Nymphicus hollandicus) in Romania.

Summary
Prostate cancer is the second most common cancer worldwide for males, and the fifth most common cancer overall. Using of autogenic training could reduce the influence of ADT and raise quality of prostate cancer patients. The aim of this study was to determine the effects of autogenic training in patients with prostate cancer. Patients were divided to experimental and control group. Experimental group participated in fourteen weeks long autogenic training program. Control group performed usual daily activities. Every subject of research performed input and output diagnostics which monitored psychical states of patients by psychological standardized tests - Differential questionnaire of depression (DDF) and Questionnaire of anxiety (STAI X1). Our data showed autogenic training program significant improved depressions symptoms and anxiety in experimental research group (p ≤ 0.05), however there was no main change of depression symptoms and anxiety values for control group (p = n.s.).
Changes In Functional Movement Screen Scores Of Slovak Women’s National Football Teams

Published: October 2015

Abstract
The aim of this study was to assess movement patterns by using Functional Movement Screen in three categories of Slovak women’s national football teams during two occasions interpressed with one year. The reason for this was to answer the questions: 1. if there is a tendency to perform better in the screen with respect to age category, and 2. if the players who did the screen more times and recieve recommendations, perform better after a year, irrespective to age category. Our results showed that every category achieved significant improvements (p<0.10) in total test score when compared the two occasions (2013 vs. 2014), except WU17, where significant decrement was found (p<0.01). These results probably represent the fact, that the WU17 is the less experienced category regarding FMS™, and the group where the most turbulence occurs in the nomination list. However, when we assessed the group of players who were present at both occasions of screening, irrespectively to age group they belong, results revealed significant overall improvements (p<0.05). In conclusion, we would suggest FMS™ as a useful tool to reveal potentially weak links in player's movement and therefore determine injury risk. Our results suggest that professional recommendations to remove these are effective and at least as much important as the screening scores alone.

Authors: Žuffová Zuzana , Zapletalová Ludmila 
Published: October 2015

Abstract
The aim of the study was to verify the efficiency of two frisbee ultimate teaching models at 8-year grammar schools relative to age. In the experimental group was used a game based model (Teaching Games for Understanding) and in the control group the traditional model based on teaching techniques. 6 groups of female students took part in experiment: experimental group 1 (n=10, age=11.6), experimental group 2 (n=12, age=13.8), experimental group 3 (n=14, age =15.8), control group 1 (n=11, age =11.7), control group 2 (n=10, age =13.8) and control group 3 (n=9, age =15.8). Efficiency of the teaching models was evaluated based of game performance and special knowledge results. Game performance was evaluated by the method of game performance assessment based on GPAI (Game Performance Assessment Instrument) through video record. To verify level of knowledge, we used a knowledge test, which consisted of questions related to the rules and tactics knowledge of frisbee ultimate. To perform statistical evaluation Mann-Whitney U-test was used. Game performance assessment and knowledge level indicated higher efficiency of TGfU in general, but mostly statistically insignificant. Experimental groups 1 and 2 were significantly better in the indicator that evaluates tactical aspect of game performance - decision making (p<0.05). Experimental group 3 was better in the indicator that evaluates skill execution - disc catching. The results showed that the students of the classes taught by game based model reached partially better game performance in general. Experimental groups achieved from 79.17 % to 80 % of correct answers relating to the rules and from 75 % to 87.5 % of correct answers relating to the tactical knowledge in the knowledge test. Control groups achieved from 57.69 % to 72.22 % of correct answers relating to the rules and from 51.92 % to 72.22 % of correct answers relating to the tactical knowledge in the knowledge test.
On Computer-Assisted Proving The Existence Of Periodic And Bounded Orbits
Authors: Srzednicki Roman 
Published: October 2015

Abstract
We announce a new result on determining the Conley index of the Poincaré map for a time-periodic non-autonomous ordinary differential equation. The index is computed using some singular cycles related to an index pair of a small-step discretization of the equation. We indicate how the result can be applied to computer-assisted proofs of the existence of bounded and periodic solutions. We provide also some comments on computer-assisted proving in dynamics.

Influence of nuclear power unit on decreasing emissions of greenhouse gases
Authors: Stanek Wojciech , Szargut Jan , Kolenda Zygmunt , Czarnowska Lucyna 
Published: October 2015

Abstract
The paper presents a comparison of selected power technologies from the point of view of emissions of greenhouse gases. Such evaluation is most often based only on analysis of direct emissions from combustion. However, the direct analysis does not show full picture of the problem as significant emissions of GHG appear also in the process of mining and transportation of fuel. It is demonstrated in the paper that comparison of power technologies from the GHG point of view has to be done using the cumulative calculus covering the whole cycle of fuel mining, processing, transportation and end-use. From this point of view coal technologies are in comparable level as gas technologies while nuclear power units are characterised with lowest GHG emissions. Mentioned technologies are compared from the point of view of GHG emissions in full cycle. Specific GHG cumulative emission factors per unit of generated electricity are determined. These factors have been applied to simulation of the influence of introduction of nuclear power units on decrease of GHG emissions in domestic scale. Within the presented simulations the prognosis of domestic power sector development according to the Polish energy policy till 2030 has been taken into account. The profitability of introduction of nuclear power units from the point of view of decreasing GHG emissions has been proved.
Influence of the type of working fluid in the lower cycle and superheated steam parameters in the upper cycle on effectiveness of operation of binary power plant
Authors: Stachel Aleksander A. , Wiśniewski Sławomir 
Published: October 2015

Abstract
In the paper presented have been the results of the analysis of effectiveness of operation of binary power plant consisting of combined two Clausius-Rankine cycles, namely the binary cycle with water as a working fluid in the upper cycle and organic substance as a working fluid in the lower cycle, as well as a single fluid component power plant operating also in line with the C-R cycle for superheated steam, with water as a working fluid. The influence of the parameters of superheated steam in the upper cycle has been assessed as well as the type of working fluid in the lower cycle. The results of calculations have been referred to the single-cycle classical steam power plant operating at the same parameters of superheated steam and the same mass flow rate of water circulating in both cycles. On the basis of accomplished analysis it has been shown that the binary power plant shows a greater power with respect to the reference power plant.
Technical and economic aspects of oxygen separation for oxy-fuel purposes
Authors: Chorowski Maciej , Gizicki Wojciech 
Published: October 2015

Abstract
Oxy combustion is the most promising technology for carbon dioxide, originated from thermal power plants, capture and storage. The oxygen in sufficient quantities can be separated from air in cryogenic installations. Even the state-of-art air separation units are characterized by high energy demands decreasing net efficiency of thermal power plant by at least 7%. This efficiency decrease can be mitigated by the use of waste nitrogen, e.g., as the medium for lignite drying. It is also possible to store energy in liquefied gases and recover it by liquid pressurization, warm-up to ambient temperature and expansion. Exergetic efficiency of the proposed energy accumulator may reach 85%.

Published: October 2015

Abstract
This article presents a comparative study of hooks’ characteristics of ring, rotor, air-jet and open-end friction spun yarns. Hook types and their extent, spinning in-coefficient and mean fibre extent in the yarns produced on different spinning technologies are investigated. The results show that the hook extents for open-end friction spun yarn are the highest followed by rotor, ring and air-jet spun yarns. Ring and air-jet spun yarns have higher percentage and extent of trailing hook as compared with leading hook, whereas, rotor and friction spun yarns show the reverse trend.
Influence of alfalfa protein concentrate dietary supplementation on blood parameters of growing-finishing pigs
Authors: Pietrzak Krzysztof , Grela Eugeniusz R. 
Published: October 2015

Abstract
The aim of the study was to analyse the effect of the feed additive alfalfa protein concentrate (APC), on pig health. The trial involved 40 crossbred gilts and 40 crossbred castrates (Polish Landrace × Polish Large White) × Duroc of 29.0 ± 0.5 kg initial body weight. Allocation of experimental animals was into four treatment groups: the control group (C) was fed standard mixtures, without APC addition; group E-15 was fed a basal diet supplemented with 1.5% APC; and groups E-30 and E-30P were fed diets with 3.0% APC inclusion. There were two feeding systems. In the first system, animals of groups C, E-15, and E-30 were fed continuously with suitable mixtures. The second feeding system was used in group E-30P where animals received the experimental or control mixture alternating at two-week intervals. The addition of APC supplement to diets significantly increased (P ≤ 0.05) red blood cell indices, i.e. haematocrit (Ht), red blood cell count (RBC), and haemoglobin concentration (Hb) in growing and finishing periods. The analysis of enzyme activity demonstrated a markedly higher activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and especially alkaline phosphatase (ALP) in the blood plasma of pigs fed APC supplement. This increase may indicate a negative impact of APC on the animal’s liver. A positive effect of dietary APC on blood lipid parameters was associated with a decreased level of total cholesterol and reduced low-density lipoprotein fraction. Analysis of the haematological and biochemical blood indices demonstrated that APC additive may affect animal health.
“Improvisation is not allowed in a second language”: A survey of Italian lecturers’ concerns about teaching their subjects through English
Authors: Helm Francesca , Guarda Marta 
Published: October 2015

AbstractEnglish-medium instruction (EMI) is increasingly being introduced not only in universities in northern Europe but also in central and southern countries, such as Italy. However, the competences and concerns of the lecturers involved are not always considered when such developments are introduced, and support or training may not be offered. This paper reports on a survey on EMI to which 115 lecturers in a public university in northern Italy responded. The survey was carried out by the university’s Language Centre as part of the LEAP (Learning English for Academic Purposes) Project, which was developed to support lecturers in EMI. The survey sought to identify what the lecturers perceived as their strengths and weakness in English, their concerns, and also their evaluations of the experience of teaching through English if they had any. The findings discussed in this paper shed light on the needs of lecturers who are involved in EMI, which relate to methodology as well as language issues. The implications of this for European university language centres intending to support EMI at their universities are discussed in the conclusion.
