Abstract
Despite the long research history on the genus Coelastrella, its species diversity and biotechnological potential have not been fully explored. For the first time, cluster analysis of morphological characteristics was done in the representatives of the said genus. The results obtained have shown that morphological similarity does not necessarily indicate a molecular genetic relationship. It the light of it, the taxonomic status of species can reliably be determined using specific DNA region, such as 18S-ITS1-5.8S-ITS2. The V4 and V9 regions of gene 18S rRNA are relatively conservative fragments which are not suitable for species identification. The ITS2 can be used as a "short barcode". Among the advanced machine methods for delimitation species, the most effective algorithm for distinguishing Coelastrella species was the Generalized Mixed Yule Coalescent (GMYC) method. This paper represented for the first time our comprehensive review of the works devoted to the analysis of the biotechnological potential of representatives of the genus Coelastrella and shows that fatty acid composition of the three main chemogroups within the studied genus differs. In the future, this may form the basis for predicting the composition of the fatty acid profile of new strains, which is important while searching for organisms with specified biotechnological properties. In conclusion, an integrative approach was employed to describe Coelastrella affinis sp. nov., a new species of the genus Coelastrella with high biotechnological potential. Also, a new description of C. thermophila var. astaxanthina comb. nov. was proposed.

Abstract
The aim of the study is to determine whether the assessment of postoperative pain and timely measures to control it improve the quality of medical care in intensive care units (ICUs). To develop an improvement model with a focus on pain assessment and control. 151 patients were included in the study, divided into two groups: a retrospective group (RG)-60 patients and a prospective group (PG)-91 patients. A multimodal approach to pain control was applied to all patients. We administered the Critical Care Pain Observational Tool (CPOT) to PG upon admission to the ICU. Visual analog scale (VAS) for pain assessment was used in all non intubated patients in 6 hours intervals. In the PG, а model for improvement was applied using a PDSA (Plan, Do, Study/ Check, Act) cycle. The following indicators have been used: process, outcome, and balancing indicators. A survey of the PG was also conducted. The developed Model of improvement increased the VAS score reporting success rate from 40 to 95%, which allowed significantly better pain control. In PG the registered CPOT score was 1.71 ± 0.73. 90% of patients in PG have an average VAS score below 5 after the improvement model, while in RG-50% of patients, which is statistically significant (P < 0.001). There was no statistically significant difference in balancing indicators between the two groups. Conclusion: The conducted survey confirmed the positive effect of the model. Quality improvement in the ICU depends on accurate assessment of postoperative pain and timely and adequate treatment.

Abstract
The Adolescent Brain Cognitive Development (ABCD) Study® is a 10-year longitudinal study of children recruited at ages 9 and 10. A battery of neuroimaging tasks are administered biennially to track neurodevelopment and identify individual differences in brain function. This study reports activation patterns from functional MRI (fMRI) tasks completed at baseline, which were designed to measure cognitive impulse control with a stop signal task (SST; N = 5,547), reward anticipation and receipt with a monetary incentive delay (MID) task (N = 6,657) and working memory and emotion reactivity with an emotional N-back (EN-back) task (N = 6,009). Further, we report the spatial reproducibility of activation patterns by assessing between-group vertex/voxelwise correlations of blood oxygen level-dependent (BOLD) activation. Analyses reveal robust brain activations that are consistent with the published literature, vary across fMRI tasks/contrasts and slightly correlate with individual behavioral performance on the tasks. These results establish the preadolescent brain function baseline, guide interpretation of cross-sectional analyses and will enable the investigation of longitudinal changes during adolescent development.

Introduction
In the acute period of myocardial infarction (MI) inflammatory disorders of blood are registered, but data of prognostic significance of these disorders is multiple-valued.
Purpose
Research of manifestation of the inflammatory response in patients who suffered MI, and estimation of its prognostic significance.
Materials and methods
772 patients with myocardial infarction were examined. Prospective follow-up from 1 to 7 years was performed.
Results
The death rate during all years of follow-up was 14,2 % of all included in the study. 61% of patients died suddenly, but 26% of them died as a consequence of the progression of chronic cardiac insufficiency. In patients died suddenly lower level of lymphocytes in the first 24 hours: 1,30 ± 0,47 * 109/l vs 1,80 ± 0,73*109/l, (p = 0,03) was registered. In patients who died due to heart failure progression, authentically registered higher leukocytosis in the first 24 hours, in comparison to survived ones, reached 13,83 ± 6,00*109/l (vs 11,9 ± 3,12*109/l; p = 0,005), but to 5th day in the compared groups leukocytes levels had practically the same values (7,36 ± 1,89*109/l vs 7,47 ± 1,99*109/l; accordingly p = 0,8). In the compared groups the number of lymphocytes, expressing CD 95 did not differ authentically, but in died abruptly patients this index was rather lower.
There were not authentic differences detected among groups of dead and survived patients, in terms of interleukins 1β,2, and 6, whereas TNF-α was almost twice as high in patients who died due to CHF progression. Studying inflammatory markers were not included in the number of independent indexes, connected with the risk of death when conducting multivariate regressive Cox-analysis.
Conclusion
In our opinion, inflammatory factors were displaced from the prognostic model for assessing the risk of death, both sudden and due to heart progression, by more powerful structural-functional predictors.

Abstract
Kashkaval is a hard cheese produced in Eastern Europe and consumed after ripening. The influence of ripening temperature (9±1°C, 11±1°C and 13±1°C) of cow's milk Kashkaval cheese on its physicochemical, microbiological and sensory characteristics was studied. For the ripening period no statistically significant differences (P>0.05) in the indicators dry matter, fat content, salt and protein were found. A slight decrease in active acidity was observed during the maturation process which tendency was more pronounced in the experimental samples ripened at higher temperatures (13.0±1.0°C). It was found that lowering the ripening temperature of Kashkaval cheese was accompanied by a prolongation of the lag phase in the development of lactic acid microflora. A significantly higher amount of lactic acid microorganisms (P<0.05) in cheese samples matured at 13±1° C was established. The chosen temperature regime of maturation did not affect the number of psychrotrophic microorganisms (P>0.05). The absence of unwanted side microflora in fresh cheese was established, which was an important prerequisite for the normal course of the maturing processes and the formation of a characteristic sensory profile of the cheese. Kashkaval cheese ripened at 13±1°C for 45 days was characterized by the highest overall sensory score comparable to Kashkaval cheese ripened at 9±1°C and 11±1°C for 60 days. The obtained results demonstrated that the higher ripening regime could be successfully used to reduce production costs without changing the specific physicochemical, microbiological and sensory characteristics of Kashkaval cheese from cow milk.

Abstract
Early diagnosis of benign prostatic hyperplasia (BPH) in dogs using imaging methods has become increasingly prevalent in recent years. That allows accurate differentiation of BPH from other diseases, as well as timely prophylaxis and treatment. The aim of the research was to make a comparative analysis of BPH diagnosis by ultrasound, X-ray and computed tomography (CT) and computer-assisted sperm analysis (CASA) of ejaculates from sexually mature male dogs. Two hundred and fifty patients of different breeds, 80 of whom with previous clinical history and BPH-related complaints at 3 to 7 years of age, were followed. The results of echographic studies of dogs with clinical signs of BPH showed structural prostate changes. Focal inflammation, small or larger intra- or paraprostatic cysts (7%), neoplasia (3%), acute or chronic prostatitis (15%) and prostate abscesses (3%) were detected. The remaining 72% of patients demonstrated evidence of hypo -to hyper heterogenic parenchyma with moderate heterogeneity, which are characteristic of BPH. X-ray findings about prostate volume showed that 85% of the patients studied had an increase in prostate volume, enlarged soft tissue shadow in the caudal abdomen or cranially to the pelvis but caudally to the bladder. These data were found out in 13% more patients than those with ultrasound data for BHP. In this study, computed tomography demonstrated structural changes and precise prostate size in all 10 patients with suspected BPH. The CASA results showed that the percentage of static sperm was significantly higher in dogs with BPH than in healthy dogs. At the same time, there was a decline in the percentage of cells with progressive movement at a rapid and medium rate of movement in patients with BPH compared to those data in healthy dogs. These changes could have a negative effect on the fertilising potential of the sperm. The obtained results suggested that the application of CT and CASA for early diagnosis of BPH in dog breeders from rare and valuable breeds is advisable and useful for timely prevention and treatment of the disease.

Abstract
In this study the individual profiles of seminal plasma proteins (SPP) in rams of three breeds – Merino, Pleven Blackhead and Ile de France - were analysed. The study was carried out with three rams at 3, 6 and 10 years of age, grown and fed under similar conditions. Eighteen ejaculates (6 ejaculates from each ram) were evaluated by Sperm Class Analyzer. The total SPP concentration was measured spectrophotometrically. The separation and characterisation of SPP was performed by HPLC and one dimensional polyacrylamide gel electrophoresis (SDS-PAGE). There were no significant differences between the characteristics of ejaculates and the main kinematic parameters of the sperm in the breeds studied. Chromatograms showed specific profiles with 9, 10 and 11 protein peaks for Merino, Pleven Blackhead and Ile de France breeds, respectively. The total SPP concentration was the highest in the Pleven Blackhead breed and the lowest in Ile de France breed. The major parts of SPP in the three breeds were identical. The seminal plasma of Merino breed contained proteins with molecular mass of 30.3 kDa, 15.7 kDa and 15.2 kDa that were not present in the other two breeds. In the Ile de France and Pleven Blackhead samples only, two proteins with molecular masses of 39.7 kDa and 21.1 kDa, were observed. In conclusion, the detection of specific proteins can be used as a biological marker for sheep breed identification.

Abstract
In the present study, a comparative analysis was undertaken on the possibilities of using
olive oil in fresh spreadable cheese either emulsified or encapsulated. The changes in
titratable acidity, active acidity and total Lactococcus count were recorded continuously
throughout the storage period. At the end of the storage period, Lactococcus count in the
samples with encapsulated oil were found to be slightly higher (7.7 and 7.8 log CFU.g-1
respectively) in comparison with the control sample (7.5 log CFU.g-1
). A significantly
higher content (P < 0.05) of unsaturated fatty acids (56.88 g per 100 g fatty acids) and a
lower peroxide value of extracted fat (0.35 meqO2.kg-1
) were found in the fresh spreadable
cheese samples with 4% (w/w) encapsulated olive oil and extract of dill used as
antioxidant in an amount of 0.003% (v/v). The addition of antioxidant (dill extract) further
reduced oxidation process and enhanced cheese functionality. The sensory profile of the
fresh cheeses, containing encapsulated oil, was better compared to the sensory profile of
the products prepared with directly added olive oil (with or without added antioxidant).

Abstract
The importance of control for nosocomial and community-acquired infections is one of the priorities of practical surgery, and maxillofacial surgery is no exception in this matter. Aim of study - to determine the spectrum of antimicrobial activity of widespread antiseptics and antibacterial agents used for topical treatment of odontogenic phlegmons of the maxillofacial region. A bacteriological study of purulent wound exudate was carried out for 109 patients of the maxillofacial hospital department with a diagnosis of odontogenic phlegmons. Using the method of "draw-wells" the sensitivity of the isolated bacterial cultures to solutions of decamethoxin, dioxidine, formaldehyde, and sanguiritrin was determined. Using the dilution method microbicide concentrations of decamethoxin and miramistin were determined by influencing the clinical and museum strains of pathogenic bacteria. In purulent exudate the monocultures of staphylococci were determined - 79 (40.1%), and streptococci - 86 (43.65%), aerobic non-fermenting bacteria - 11 (5.60%) and enterobacteria - 21 (10,65%) were found much less often. Isolated from S. aureus and E. coli proved to be sensitive to solutions of decamethoxin, formaldehyde and sanguiritrin; isolated strains of P. aeruginosa - only to decamethoxin and formaldehyde. Microbicide concentrations of decamethoxin were 4-35 times lower than miramistin due to effect on clinical and museum strains of bacteria. Efficiency of decamethoxin was higher.

Abstract
Chromaffin cells of adrenal medulla have traditionally been considered as modified sympathetic neurons. However, the results of recent studies indicate the need to revise this concept. The article reviews recent findings in origin and ontogeny of adrenal chromaffin cells and transcriptional and posttranscriptional regulation of developmental processes. The article summarizes data on transcriptional control of chromaffin cells proliferation and maturation and participation of microRNA in regulation of chromaffin and sympathetic neuronal phenotype gene expression.

Abstract
In addition to accumulation and metabolism of triglycerides, white adipose tissue is recognized as the active endocrine organ, whose dysfunction is associated with the development of a wide range of diseases. The secretome of adipocytes is represented by a wide range of adipokines, which vary in depot and sex-specific manner. In addition, adipokines have diverse biological effects, correlations with different metabolic features and functions. In this review, the data on biological effects, origin and the clinical significance of adipokines are discussed. The influence of adipokines on metabolism, sensitivity to insulin, vascular homeostasis, angiogenesis, repair, inflammation and immune cells are shown. Visceral adipose tissue accumulation is accompanied with adipocytes hypertrophy and overproduction of such proinflammatory and proaterogenic molecules like resistin, visfatin, vaspin, tumor necrosis factor, interleukin 6, lipocalin, glypican 4, RBP4 etc. There is a tight correlation between these adipokines level and development of insulin resistance, type 2 diabetes, cardiometabolic complications and cancer. Thus, adipokines represent a group of informative biomarkers for the diagnostics of metabolic disorders and the prediction of the outcome of the wide range of diseases. The study of the effects and mechanisms of the action of adipokines is the basis for determining new targets for therapy.

Abstract
The requirements for quality control (QC) in diagnostic radiology were introduced in Bulgarian legislation in 2005. Hospital medical physicists and several private medical physics groups provide QC services to radiology departments. The aim of this study was to analyse data from QC tests in mammography and to investigate the impact of QC introduction on mammography practice in the country. The study was coordinated by the National Centre of Radiobiology and Radiation Protection. All medical physics services were requested to fill in standardised forms with information about most important parameters routinely measured during QC. All QC service providers responded. Results demonstrated significant improvement of practice since the introduction of QC, with reduction of established deviations from 65 % during the first year to 7 % in the last year. The systems that do not meet the acceptability criteria were suspended from use. Performance of automatic exposure control and digital detectors are not regularly tested because of the absence of requirements in the legislation. The need of updated guidance and training of medical physicists to reflect the change in technology was demonstrated.

Abstract
The resistance patterns of Campylobacter spp. isolated from retail broiler chicken meat originating either from Estonia, Lithuania or Latvia collected in Estonia were determined. Additionally, in collaboration with the laboratories of several Estonian hospitals, antimicrobial susceptibility patterns were determined for Campylobacter isolates from patients with severe Campylobacter enteric infections. The isolates were identified at the species level by the PCR method. Respectively, 88.8% of the isolates were C. jejuni, and 11.2% were C. coli. In total, 126 Campylobacter isolates of broiler chicken meat and human origin were tested for minimal inhibitory concentrations (MICs) with the broth microdilution VetMIC(TH) method (National Veterinary Institute; Uppsala, Sweden) for a total of six antimicrobials. Resistance to one or more antimicrobials was detected in 62 (63.3%) of Campylobacter broiler chicken meat isolates and in 20 (71.4%) of human-origin isolates. Large proportions of the broiler chicken meat isolates were resistant to ciprofloxacin (60.2%). Multidrug resistance (i.e. to three or more unrelated antimicrobials) was detected in five (5.1%) C. jejuni isolates. Among the human isolates, 20 (71.4%) were resistant to fluoroquinolones, and two (7.1%) C. jejuni isolates exhibited multidrug resistance. The chicken meat isolates of Estonian origin were the most susceptible. However, a high proportion of fluoroquinolone-resistant C. jejuni isolates were found in Latvian and Lithuanian products. The results of this study indicate that the problems caused by the inappropriate use of antimicrobials extend beyond the country in which a food originates; therefore, both domestic and international interventions and agreements are required to implement common policies on antimicrobial usage and to minimize the emergence of Campylobacter drug resistance.

Abstract
There are a variety of definitions for "non-thermal effects" included in different international standards. They start by the simple description that they are "effects of electromagnetic energy on a body that are not heat-related effects", passing through the very general definition related to low-level effects: "biological effects ascribed to exposure to low-level electric, magnetic and electromagnetic fields, i.e. at or below the corresponding dosimetric reference levels in the frequency range covered in this standard (0 Hz-300 GHz)", and going to the concrete definition of "the stimulation of muscles, nerves, or sensory organs, vertigo or phosfenes". Here, we discuss what kind of effect does the non-thermal one has on human body and give data of measurements in different occupations with low-frequency sources of electromagnetic field such as electric power distribution systems, transformers, MRI systems and : video display units (VDUs), whereas thermal effects should not be expected. In some of these workplaces, values above the exposure limits could be found, nevertheless that they are in the term "non-thermal effects" on human body. Examples are workplaces in MRI, also in some power plants. Here, we will not comment on non-thermal effects as a result of RF or microwave exposure because there are not proven evidence about the existance of such effects and mechanisms for them are not clear.
