Mycotoxicoses in children
Authors: Peraica Maja , Richter Darko , Rašić Dubravka 
Published: January 2015

Abstract
Mycotoxicoses are acute and chronic poisonings caused by mould toxins called mycotoxins. Although acute mycotoxicoses, caused by high mycotoxin levels in food are rare nowadays, they need to be described in order to inform physicians and other health care workers about their symptoms. Children are more sensitive to mycotoxins because of their lower body mass, higher metabolic rate, and underdeveloped organ functions and detoxication mechanisms. Some mycotoxicoses appear only in children, and some are more pronounced in children than in adults. Acute mycotoxicoses in children are reported poorly, mostly because they occur in the tropical regions with poor healthcare coverage. In developed countries healthcare authorities are more concerned about child exposure to low levels of mycotoxins with immunotoxic, genotoxic or carcinogenic properties

Abstract
The need to reduce pollution to levels that minimize adverse effects on human health involve the monitoring of air quality, including dry depositions and their metal content. The analysis of these parameters aims to investigate the air quality in Maramures County (with nonferrous mining activities) and in the Romanian - Ukraine transboundary area. The paper presents the experimental results obtained for dry atmospheric deposition of copper and zinc using flame atomic absorption spectrometry (FAAS). The samples were collected from four location/cities of Maramures County (Baia Mare, Sighetu Marmatiei, Viseu de Sus and Borsa) during May-October 2014. The highest average values of copper concentration in the dry depositions were found in Baia Mare (199.88 μg/g), that is the most important industrial centre in Maramures County, followed by Borsa (111.49 μg/g), that used to be a nonferrous mining centre. In Viseu de Sus and Sighetu Marmatiei the average concentrations of copper in the dry depositions were lower: 75.63 μg/g and 64.26 μg/g, respectively. Zn average concentrations in dry depositions were 6.4-12 times higher than Cu concentrations. In Viseu de Sus and Borsa relative high values of Pearson correlation coefficients between the logarithm of Cu and Zn content in the dry deposition were found (0.702 and 0.737, respectively) estimating that both pollutants in the ambient air have the same sources, probably the re-suspension of the dust from the tailing ponds. This study is implemented within the frame of ENPI Cross-border Cooperation Programme Hungary-Slovakia-Romania-Ukraine 2007-2013, in the project Clean Air Management in the Romania-Ukraine Transboundary Area - (CLAMROUA), financed by the European Union
Myofibroblasts in Normal and Fibrotic Liver in Different Animal Species
Authors: Vladimir Kukolj 
Published: January 2015

Abstract
Myofibroblasts, cells sharing characteristics with fibroblasts and smooth muscle cells, may have a very heterogeneous origin. The myofibroblasts may be derived from a variety of sources including resident mesenchymal cells, epithelial to mesenchymal transition, as well as from circulating fibroblast-like cells called fibrocytes that are derived from bone-marrow stem cells, or derived from bone marrow precursors. In normal conditions, fibroblastic cells exhibit a low extracellular matrix production ability. After tissue injury, they become activated by cytokines locally released from inflammatory and resident cells to migrate into the damaged tissue and to synthesize extracellular matrix components. The investigation of cytoskeletal and cell surface markers showed a certain degree of heterogeneity of these cells. The reason for this is that markers these cells express to a large extent depend on the type of animal, age and stage of development of fibrosis. A better knowledge of the molecular mechanisms involved in the appearance of differentiated myofibroblasts in different pathological situations will be useful for understanding the development of fibrosis, its prevention and therapy

Published: January 2015

Abstract
Despite medical advancements, the development of an ideal vascular prosthesis still poses a great challenge. In this study the researchers tried to test and verify the characteristics of a new type of vascular prosthesis, using adiponectin (Adipograft Ra 1vk 7/350) developed at the Knitting Research Institute, a.s. Brno. Two types of vascular prostheses (12 with adiponectin and 6 as a control without adiponectin) were implanted in nine healthy 4-year-old Merino sheep. The implantation site was the common carotid artery and the length of the implant was 10 cm. We applied the theory of the protected coagulum, whereby all sheep received antibiotics as a prophylactic measure. A Doppler U.S. was performed before finishing each operation, in order to verify the patency of the prostheses. Each animal was followed up during the whole study and the prostheses were extirpated on days 30 and 100 (1 and 3 months). It was observed that all prostheses coated with adiponectin showed patency after extirpation. The lumen implants were of a consistent thickness of 7 mm. Histological study of the implanted prostheses confirmed a quick, high quality, healing. Experimental vascular prostheses coated with adiponectin appeared to be successful in clinical practice. The researchers think that Adipograft Ra 1vk 7/350 can be a turning point in the development of vascular prostheses, due to its patency and quick healing.

Abstract
The aim of this study was to compare the effects of different premedication protocols followed by a propofol/fentanyl TIVA on cardio-respiratory and hemodynamic changes in twenty-four dogs randomly divided into two groups (AMD-group: medetomidine, atropine and diazepam; AXD-group: xylazine, atropine and diazepam). Cardiorespiratory variables, acid-base indices, quality of sedation, induction, intubation and recovery were recorded throughout the experiment. Significant changes were observed for the pO2 level, which was increased in the AMDgroup from 90 min. (*P< 0.05) to 120 min. (**P< 0.01) of anesthesia. This can be explained by a reduction of the administration rate of propofol/fentanyl TIVA and oxygenation initiated due to excessively deep anesthesia detected by an anesthetsiologist, leading to improved ventilation and increased pO2. The pCO2 (*P < 0.05) reached more preferable values during the first 30 min. and pH (**P< 0.01) was significantly improved within the first 60 min. in the AXD-group thanks to less depressant effects of xylazine. Within the first 30 min. of anesthesia a significant heart rate difference between the groups was accompanied with significantly higher BP (hypertension) in the AXD-group (10 min. ***P< 0.001, 30 min. **P< 0.01). This points to the possibility of atropine application only in the case of a tendency to bradycardia followed by hypotension. It can be concluded that xylazine is a better option for the premedication of a propofol/ fentanyl TIVA in dogs undergoing a prolonged surgical intervention, in spite of the fact that lower sedation scores were attained. We have detected significantly less adverse cardio-respiratory and hemodynamic effects of xylazine, and a shorter recovery time when compared to medetomidine

Summary
Reproductive health implies that people are able to have a responsible, satisfying and safe sex life and that they have the capability to reproduce and the freedom to decide about it. It is directly conditioned by social, cultural and behavior factors.
One in every five people in the world is an adolescent, and 85% of them live in developing countries. In many countries, taboos and norms about sexuality pose strong barriers to providing information, health services and other forms of support needed by young people to safeguard their sexual and reproductive health.
The regulation of fertility is the most important factor that affects the reproductive health. Adolescents are not sufficiently aware of the possibility of contraception or sexually transmitted infections. In Serbia, 84% of boys and 65% girls (adolescents) have had sexual experience. Worldwide, 36-70% of adolescents do not use contraception and unwanted pregnancies are the reason for 90% of unwanted births and 89% of unsafe abortions.
There are many programs in the world which aim to increase the knowledge about preservation of reproductive health. There are not any national programs in our country for family planning and preservation of reproductive health in youth population. In national strategy for youth are given different ways of youth education in the field of health promotion, including promotion of reproductive health.
In order to ensure that adolescents have the ability to achieve good health, we must provide information and education in a timely manner, and we need to provide life skills and choices.
Unfolded Protein Response and Triad Formation in Skeletal Muscles of Catecholaminergic Polymorphic Ventricular Tachycardia Mouse / Odgovor Razvijenog Proteina I Formiranje Trijada U Skeletnim Mišićima Miševa Sa Kateholaminergičkom Polimorfnom Ventrikularnom Tahikardijom

Summary
Isoform 2 of calsequestrin (CASQ2) is the main calcium-binding protein of sarcoplasmic reticulum (SR), expressed both in cardiac and in skeletal muscles. CASQ2 acts as an SR calcium (Ca2+) sensor and regulates SR Ca2+ release via interactions with triadin, junctin, and the ryanodine receptor. Various mutations of the csq2 gene lead to altered Ca2+ release and contractile dysfunction contributing to the development of arrhythmias and sudden cardiac death in young individuals affected by catecholaminergic polymorphic ventricular tachycardia (CPVT).
Recently, a transgenic mouse carrying one of the identified CASQ2 point-mutations (R33Q) associated to CPVT was developed and a drastic reduction of the mutated protein was observed. Following a biomolecular approach, several analysis were performed using different antibody treatments in order to identify when the reduction of CASQ2 begins in skeletal muscles, unveil the mechanism involved in the reduction of CASQ2 in slow-twitch and fast twitch muscles and verify if other proteins are affected by the presence of the mutated protein.
Mutated CASQ2 decreased soon after birth. Up-regulation of proteins associated to the unfolded protein response (UPR) was also observed. Important proteins in skeletal muscle triads formation were analyzed and increased protein levels were observed in adult knock-in CASQ2-R33Q/R33Q mice.
Probably, R33Q mutation induced the decrease of CASQ2 by activation of the UPR and subsequently degradation through proteasome.

Summary
Evaluation is the most important field of efficacy in clinical education. Since knowledge of the current situation is one of the most essential requirements for planning a desirable one and students' and tutors' viewpoints act as a facilitator in this regard, we conducted this study to compare the current and desirable situation of clinical evaluation from the students' and tutors' point of view at Mashhad Faculty of Nursing and Midwifery.
In this cross-sectional study, midwifery students and tutors of the Mashhad University of medical sciences were assessed. The researcher - designed questionnaires "current and desirable situation of criteria and methods in clinical evaluation" were approved by content validity and Cronbach's alpha. Descriptive and analytic statistics were used.
Total score means of current and desirable criteria in clinical evaluation were: 55.2± 18.0 and 68.4±19.3 (of 100) from students' view, respectively; and: 47.0±18.3 and 72.3± 20.4 (of 100) from tutors' view, respectively. Mean total scores of current and desirable methods in clinical evaluation from students' point of view were: 51.5±17.9 and 56.5±18.3, respectively, and tutors': 55.6±16.0 and 69.5±14.4 (of 100), respectively.
The findings showed that the current situation of criteria and methods in midwifery clinical evaluation differs from the desirable situation, i.e. the current status score of criteria and methods is lower than the desirable ones. Therefore, we can improve the current situation with criteria and methods in clinical evaluation by using desirable situation.

Summary
Bone marrow involvement is rare in patients with Hodgkin lymphoma (HL). Its incidence varies with respect to risk factors from 4% to 14%. Low risk patients do not need trephine biopsy according to some research. In the era of positron emission tomography/computed tomography (PET/CT) staging prior to therapy, the role of trephine biopsy as a part of staging procedures becomes debatable. Many institutions worldwide created their own guidelines in the application of trephine biopsy in staging of the (HL) patients. Our institution prefers performing trephine biopsy in all risk group patients, except those who underwent PET/CT staging before therapy and if no active bone sites were found. Most of our patients are staged using multislice computed tomography (MSCT) and we perform PET/CT in the follow up after completing the induction protocol. That is why we propose the trephine biopsy to the most of our patients. A Greek group of authors have derived a clinical prediction rule for the possibility of the bone marrow involvement, which is named the Z score (Zs), and if it is ≥10, patients are at high risk for bone marrow involvement.
We present a case of a neglected, advanced (HL) patient, with the defined high risk for bone marrow involvement (Zs=25). He was clinically suspected to have affected bone marrow, which was later histologically confirmed. Unilateral trephine biopsy was performed.

Authors: Živković Nela , Stojanović Sonja 
Published: January 2015

Summary
The aim of the paper was to show the diagnostic and therapeutic approaches to a patient suffering from osteomalacia, as well as differential diagnosis with osteoporosis.
Osteomalacia (OM) is a metabolic disease of bones which appears as a result of defective mineralization of newly formed bone matrix in adults. Diagnosis of disease may represent a big problem. A 67-year-old female patient from Pirot was examined in an outpatient unit by a rheumatologist in the Niška Banja Institute in December 2012. The patient reported pain along the vertebral column and inability to get out of bed. Radiography showed vertebral compression fractures and the patient had previously received surgical care at Orthopedics Ward of General Hospital Pirot due to the left femur fracture. Orthopedist, neurologist, physiatrist and practicing rheumatologist suspected osteoporosis. The diagnosis of osteomalacia was established in February, 2013. The treatment was initiated by introducing large doses of vitamin D and advising bisphosphonates. After eighth months, the patient's general condition was improved. This was demonstrated by her independent mobility.

Alternative Approaches to a Calibration of Rainfall- Runoff Models for a Flood Frequency Analysis
Authors: Valent Peter , Szolgay Ján , Výleta Roman 
Published: January 2015

Abstract
One of the tools which are currently being used in flood frequency analysis (FFA) is rainfall-runoff (RR) modelling. Its use in FFA often confronts the problem of how to correctly calibrate RR models to extreme flows. Since FFA only deals with extreme flows, traditional calibration techniques using simple objective functions such as the Nash-Sutcliffe model’s efficiency criterion are not sufficient. In this paper we have focused on proposing alternative approaches for calibration techniques of RR models in order to enhance the description of extreme flows. We have selected the HBV type conceptual, lumped model HRON as an RR model. We have suggested two alternative calibration approaches: 1) the use of a new optimization function that compares only values higher than the 95th percentile of observed flows and 2) using two sets of parameters to separately simulate low and high flows. Each of these improvements has enhanced the simulation of extreme flows, which has been demonstrated in the empirical cumulative distribution function calculated for the simulated and observed annual maximum series of flows. The results of this paper show that improvement can be obtained by both approaches, which give good agreement between observed and simulated extreme flows, while preserving a good simulation of low and medium flows

Published: January 2015

Abstract
: The efficiency of enzyme-assisted extraction for the recovery of polyphenols from rose (Rosa damascena Mill.) petals was evaluated performing a simplex centroid experimental design for mixture with three components (pectinolytic, cellulolytic and hemicellulolytic preparation). The ternary enzyme combinations leaded to the highest contents of total polyphenols, reaching 43% higher average value as compared to the control (without enzymatic treatment) sample. Enzymatic treatments also enhanced (9−25%) the extractability of total anthocyanins. The results obtained demonstrate that enzyme-assisted extraction improves the recovery of polyphenolic antioxidants from rose petals, especially using ternary enzyme combinations, comprising pectinolytic, cellulolytic and hemicellulolytic preparation.

Abstract
Isolation and industrial exploitation of probiotics from human milk is a goal for worldwide milk biotechnology centres because of their modulation effect on the immune system in infants and adults. In the proposed study we have analysed fermentation patterns of Lactobacilli isolated from human milk, the reliability of API 50 CH carbohydrate fermentation system and a possible link between lactose concentrations and fermentation profiles on carbohydrates. We had succesfully identified three species of Lactobacillus (paracasei ssp paracasei, fermentum, acidophilus) and one unsatisfactory identification of Lactoccocus lactis ssp lactis. These strains had different carbohydrate fermentation patterns but with common characteristics and showed no statistically significant correlations between their carbohydrate metabolic trends and lactose concentrations in the milk samples.

Abstract
This paper presents the effects of temperature on gessoes that have different substances added, usually used in painting or restoration to enhance the flexibility of the ground layer or to create a suitable gesso for the specific painting technique. Five samples of gesso were made and applied on Balsa wood (a dry, stable wood that is used in restoration for completing the missing elements of the panel). After the thermal treatment, the samples were analyzed optical, by microscopy and colorimetry. The results showed small differences in colour, but no cracks of the gessoes

Seasonal Variability of Climatic Conditions for Tourism and Recreation Along the Southern Coast of the Baltic Sea
Authors: Świątek Małgorzata 
Published: January 2015

Abstract
This paper aims to indicate the periods within the year that are most and least suited to outdoor recreation along the southern coast of the Baltic Sea. The author indicates these periods based on the analysis of annual variability of several meteorological and bioclimatic parameters from the years 1981-2010 in Greifswald and Świnoujście, and from 1985 to 2010 in Hel and Gdynia. Passive recreation is favoured in July and the first half of August. The whole of the summer season has the most favourable conditions for active recreation. Good conditions frequently occur in May, and to a lesser degree in September. The advantages of May are that it has the highest sunshine duration and the lowest frequency of precipitation.
