Abstract
This study analyzed severe acute endometritis action on myometrial density and distribution of protein gene product (PGP)9.5- and calcitonin gene-related peptide (CGRP)-like immunoreactive nerve fibers and calcitonin receptor-like receptor (CLR) expression, and on CGRP receptor (CGRPR) participation in uterine contractility in pigs. E. coli suspension (E. coli group) or saline (SAL group) were injected into the uteri, or only laparotomy was performed (CON group). In the E. coli group myometrium, a lack of significant changes in PGP9.5 and CGRP innervation patterns and increased CLR protein level were revealed. In all groups, compared to the pretreatment period, human αCGRP increased amplitude in the myometrium, while reducing it in endometrium/myometrium. In the E. coli group endometrium/myometrium, human αCGRP lowered amplitude vs other groups. Human αCGRP reduced frequency in CON and SAL groups and enhanced it in the E. coli group endometrium/myometrium. The frequency in E. coli group increased vs other groups. CGRPR antagonist, human αCGRP8-37, reversed (CON, SAL groups) and eliminated (E. coli group) the rise in human αCGRP-induced myometrial amplitude. In endometrium/myometrium, human αCGRP8-37 abolished (CON group) and reversed (SAL group) a decrease in frequency, and reduced the rise in frequency (E. coli group) caused by human αCGRP. Collectively, in the myometrium, endometritis did not change PGP9.5 and CGRP innervation patterns and enhanced CLR protein level. CGRPR also mediated in CGRP action on inflamed uterus contractility.

Abstract
The recent studies indicated that the biochar (BC) may be a source of polycyclic aromatic hydrocarbons (PAHs) as well as their oxygen, nitrogen, or sulfur-containing derivatives that are considered as more toxic pollutants than their parent compounds. Here, the assessment of the impact of various biochars addition (1% wt.) to soil on barley Hordeum vulgare L. growth was presented. The concentrations of bioavailable PAHs and their derivatives in biochar were determined. PAHs increased reactive oxygen species generation resulting in oxidative stress in organisms. In this study, the response of soil-grown plants was examined in terms of the activity of the antioxidative enzymes (superoxide dismutase, catalase, peroxidase), lipid peroxidation, and the expression of genes related to oxidative stress. The results indicate that despite low content of a bioavailable fraction of parent compounds and their derivatives (up to 4.45 ± 0.24 ng gbiochar-1 and 0.83 ± 0.03 ng L-1, respectively) the biochemical response of plant was present, the activity of superoxide dismutase increased up to 2 times, but the activity of the other enzymes was lowered. The transcript level values support the studies on enzymatic activity. The presence of PAHs and their derivatives induced oxidative stress slightly but the plant was able to mitigate it.

Abstract
This article presents the results of flow visualization studies of Novec refrigerants during condensation in minichannels. Experimental investigation of two-phase flow regimes was conducted in minichannels with internal diameter dh = 2.5, 2.0, 1.2, and 0.5 mm. Images of the two-phase flow structures were analyzed by using the MATLAB algorithm. To calculate void fraction, a two-dimensional areal quantitative stereology technique was used. Observation of flow structures formed during the process of condensation was the major aim of the investigations. The condensation studies were conducted over a wide range of mass flux densities (G = 80–5500 kg/m2s) and saturation temperatures (ts = 30–70 °C). Visualization results and image analysis methods are described in this paper. Based on the experimental results, a flow structure map was constructed and presented.

Abstract
The phenolic and antioxidant potential of potentially bioaccessible fractions of lentil sprouts was studied. Sprouts were cocultivated with a probiotic to obtain a new functional product and further stored in cool conditions. The fraction obtained after buffer extraction and gastric digestion had higher content of phenolics compared to the control (by 20% and 46%, respectively); however, a 9% decrease was observed in samples obtained after gastrointestinal digestion. After gastrointestinal digestion, the highest content of phenolics (278 µg/g d.w.) was determined in the fresh control sprouts. Compounds neutralizing ABTS and hydroxyl radicals, chelating metal ions, and exhibiting strong reducing power were effectively released after gastrointestinal digestion (e.g., the values of the gastrointestinal digestibility index for chelating power and ability to quench hydroxyl radicals significantly exceeded 1 in all studied samples). It was proved that the enrichment of sprouts with a probiotic and further storage significantly improved the antioxidant potential; compared to the fresh control sprouts, an increase by 45% and 10% was determined after the gastric and gastrointestinal digestion, respectively. Lentil sprouts enriched with L. plantarum 299v may be a new functional product characterized by the high antioxidant capacity of the potentially bioaccessible fraction.

Abstract
The quality and shelf life of sprouts can be improved by postharvest application of water herb extracts. The effect of water infusions of marjoram, oregano, basil, and thyme on the phenolic content, antioxidant potential, and the microbiological and consumer quality of stored mung bean sprouts was studied. Compared to the control, the treatments increased total phenolic content. The highest amounts were determined in sprouts soaked in the thyme extract (6.8 mg/g d.m.). The infusions also inhibited the activity of enzymes utilizing phenolics, and marjoram and oregano were found to be the most effective. The increase in the level of phenolics was reflected in enhanced antioxidant properties (ability to quench cation radical ABTS•+, reducing and chelating power). Both total phenolics and flavonoids, as well as antioxidant capacities, were highly bioaccessible in vitro. All the natural extracts effectively reduced the growth of total mesophilic bacteria, coliforms, and molds (they were more effective than ascorbic and kojic acids). The treatments did not exert a negative influence on the sensory properties or nutritional value of the sprouts, and even improved starch and protein digestibility. These results are very promising and may suggest a wider used of natural extracts as preservatives of minimally processed food.

Abstract
Circulating, non-coding RNAs, such as microRNAs (miRNAs) have been proposed to be powerful pathophysiological indicators of pregnancy in animals and humans. Since their discovery, it is known that miRNAs can take part in numerous biological processes, including cell proliferation and differentiation during early embryonic development and establishment of pregnancy. Our recent studies have indicated that maternal blood can carry miRNAs reported previously at the embryo-maternal interface in pigs. To expand the scope of our research, we tested the hypothesis that miRNAs previously identified in conceptuses, trophoblasts, endometrium and uterine lumen-derived extracellular vesicles (EVs) collected before Day 20 of pregnancy can show reproductive status-dependent profiles in the serum of cyclic and pregnant crossbred pigs. Custom-designed TaqMan arrays, multiplex real-time reverse transcription (RT)-PCR and real-time RT-PCR allowed us to identify a number of reproductive status-dependent miRNAs in serum samples collected from pigs during the estrous cycle or pregnancy (Days 16 and 20). We found that serum samples were enriched with miRNAs involved in processes important during the estrous cycle and early pregnancy, e.g. cell sensitivity and viability, angiogenesis, embryonic cell proliferation and differentiation. Further validation revealed different abundance of ssc-miR-143-3p and ssc-miR-125b in pregnant and non-pregnant animals and correlation of ssc-miR-125b levels with litter size. In addition, analyzed serum samples contained both EVs and Argonaute2 proteins, which are known to be involved in miRNA transportation and intercellular communication. In summary, we identified several circulating miRNAs that differ in abundance between cyclic and pregnant animals and could serve as potential indicators of reproductive status in pigs during breeding management.

Abstract
The white beetroot cv. Śnieżna Kula is the first betanin-free beetroot registered in the European Union. The aim of this study was to compare the phenolic acids profile and antioxidant capacity of leaves of white (SK) and red (CC) beetroots and red (LC) and white (BL) Swiss chard growing in Poland. LC leaves were the richest source of total phenolics (16.55 mg GAE/g FW) and phenolic acids (1.81 mg/g FW), while the highest content of flavonoids was determined in CC leaves (1.6 mg QE/g FW). The highest antiradical activity was observed for LC, whereas CC extract exhibited the highest chelating power. BL and CC leaf extracts demonstrated high LOX inhibitory potential (EC50 = 53.23 and 56.97 mg FW/mL, respectively). An uncompetitive type of LOX inhibition was obtained for all extracts. SK extracts demonstrated the highest XO inhibitory activity (EC50 = 81.04 mg FW/mL). A noncompetitive type of XO inhibition was obtained in both extracts from red leaves (CC and LC), whereas an uncompetitive mode of inhibition was observed in the case of white leaf (SK and LC) extracts. Thus, it can be assumed that the presence of betanin influences the XO inhibition mechanism.

Abstract
Gastric digests from mung (MBS) and adzuki (ABS) bean sprouts enriched with probiotic Lactobacillus plantarum 299v were tested for their antioxidant potential, as well as antiproliferative and antimotility properties, in human stomach cancer cells (AGS). The digest of ABS contained quercetin and kaempferol derivates, while kaempferol and apigenin derivates were dominant in MBS. Compared to the controls, the probiotic-rich sprouts had a higher antioxidant potential—by 13% and 9%, respectively. Adzuki bean sprouts decreased the viability of AGS already at low concentrations (25% motility inhibitions). MBS and ABS displayed dose-independent cytostatic effects. The ABS extracts decreased the proliferation of AGS more effectively than the MBS extracts—0.2‰ ABS exerted c.a. 70% of inhibitions. Moreover, the phytochemicals from the probiotic-rich sprouts considerably reduced this activity. The increased vinculin level, the apoptotic shape of cell nuclei, and the reduced cell motility and proliferation indicate that the extracts exhibited cytostatic and cytotoxic activity.

Abstract
The effect of basil leaf (BLE) and wheat bran (WBE) extracts (potent anti-browning agents), on the phenolic content, antioxidant potential, microbiological quality, and consumer quality of shredded lettuce during storage were studied. Treatment of lettuce with increasing concentrations of BLE proportionally increased the total phenolic content and antioxidant properties. Compared to the control, the treatment enhanced the antiradical properties. This was especially visible during the analysis of the chemical extracts, while this effect was not retained in the potentially bioaccessible fraction. In the lettuce stored for 8 days, the highest reducing potential and ability to quench radicals were observed in samples treated with 1% BLE-33 mg Trolox equivalent/g d.m. and 2.8 mg Trolox equivalent/g d.m., respectively. Compounds exhibiting antiradical properties were easily bioaccessible in vitro. There was no negative effect of the treatments on the consumer quality. Most importantly, after 8 days of storage, lettuce treated with the studied extract, except 10% WBE, had higher microbiological quality. After 8-day storage, the coliforms count was reduced by 84% and 88% in samples treated with 0.5% BLE and 10% WBE, respectively. In conclusion, treatments of shredded lettuce with BLE and WBE maintain or even improve its quality during storage.

Abstract
The magnitude of the orbital magnetic moment and its role as a trigger of the Verwey transition in the prototypical Mott insulator, magnetite, remain contentious. Using 1s2p resonant inelastic x-ray scattering angle distribution (RIXS-AD), we prove the existence of noncollinear orbital magnetic ordering and infer the presence of dynamical distortion creating a polaronic precursor for the metal to insulator transition. These conclusions are based on a subtle angular shift of the RIXS-AD spectral intensity as a function of the magnetic field orientation. Theoretical simulations show that these results are only consistent with noncollinear magnetic orbital ordering. To further support these claims we perform Fe K-edge x-ray magnetic circular dichroism in order to quantify the Fe average orbital magnetic moment.

Abstract
Nutrient content and digestibility as well as factors with a potentially negative effect on these parameters were studied in legume sprouts enriched with L. plantarum 299v. The nutrient digestibility and contents were not strongly affected by the co-culture of the probiotic and sprouts. The highest digestibility of starch was observed for adzuki bean preparations (from 91.6% to 95.5%), while the lowest value was noted for soybean preparations (from 49.6% to 60.8%). A slight decrease in starch digestibility was observed in adzuki and soybean sprouts enriched with the probiotic (by about 5% and 7% respectively). An increase in starch digestibility was noted in lentil and mung bean sprouts. A key influence on protein digestibility was exerted by the activity of trypsin and chymotrypsin inhibitors. Generally, there was no negative effect of the studied factors on starch digestibility. Most importantly, the control and probiotic-rich sprouts retained high quality after cold storage.

Abstract
The effect of elicitation with arachidonic and jasmonic acids on the production of phenolic compounds as well as the antioxidant and anti-inflammatory properties of phenolic extracts of wheatgrass was evaluated. The qualitative and quantitative analysis of phenolic compounds carried out with the UPLC-MS technique indicated that luteolin and apigenin derivatives were the dominant flavonoids, while ferulic acid derivatives and syringic acid were the main components in the phenolic acid fraction in the wheatgrass. No qualitative changes in the examined phenolic compounds were observed in the case of the control and elicited plants, while there was an increase in the content of some compounds. The antioxidant activity increased in the elicited samples (with the exception of reducing power) and this elevation was partially correlated with the increase in the polyphenol content in the studied plants. Elicitation with 0.01 µM arachidonic acid also caused improvement of potential anti-inflammatory properties of the wheatgrass.

Abstract
INTRODUCTION Alopecia areata and frontal fibrosing alopecia are common causes of eyebrow loss (madarosis). OBJECTIVE Assessment of trichoscopic markers of eyebrow loss in alopecia areata and frontal fibrosing alopecia. MATERIALS AND METHODS The analysis included 50 patients with scalp alopecia areata with madarosis, 50 patients with scalp frontal fibrosing alopecia with madarosis and 50 healthy controls. In every case, trichoscopy of the eyebrow area was performed. RESULTS Empty follicular and eccrine duct openings were observed in all patients and presented predominantly as yellow dots. Exclamation mark hairs were only detected in patients with alopecia areata (30%). Tapered hairs, broken hair, black dots and Pohl-Pinkus constrictions were observed in 14%, 36%, 26% and 4% of patients with alopecia areata, respectively, 4%, 16%, 2% and 0% of patients with frontal fibrosing alopecia, respectively, and they were not present in healthy controls. Dystrophic hairs and whitish areas were observed only in patients with frontal fibrosing alopecia (28% and 32%, respectively). Eyebrow regrowth in distinct directions was present in 32% of patients with frontal fibrosing alopecia, 8% of patients with alopecia areata and 4% of healthy controls. Diffuse erythema was detected in 60% of patients with alopecia areata and frontal fibrosing alopecia and 56% of healthy controls. Vellus hairs and upright regrowing hairs were observed in patients with alopecia areata (62% and 58%, respectively), frontal fibrosing alopecia (60% and 84%, respectively) and healthy controls (100% and 100%, respectively). CONCLUSION Trichoscopy of the eyebrow area is useful in diagnosing patients with isolated eyebrow loss. The most characteristic trichoscopic features of eyebrow loss in alopecia areata include exclamation mark hairs, tapered hairs, broken hairs and black dots. Frontal fibrosing alopecia of the eyebrows is characterized by the presence of dystrophic hairs, white areas and eyebrow regrowth in distinct directions.

Abstract
SummaryObjectives: Rule induction is one of the major methods of machine learning. Rule-based models can be easily read and interpreted by humans, that makes them particularly useful in survival studies as they can help clinicians to better understand analysed data and make informed decisions about patient treatment. Although of such usefulness, there is still a little research on rule learning in survival analysis. In this paper we take a step towards rule-based analysis of survival data.Methods: We investigate so-called covering or separate-and-conquer method of rule induction in combination with a weighting scheme for handling censored observations. We also focus on rule quality measures being one of the key elements differentiating particular implementations of separate-and-conquer rule induction algorithms. We examine 15 rule quality measures guiding rule induction process and reflecting a wide range of different rule learning heuristics.Results: The algorithm is extensively tested on a collection of 20 real survival datasets and compared with the state-of-the-art survival trees and random survival forests algorithms. Most of the rule quality measures outperform Kaplan-Meier estimate and perform at least equally well as tree-based algorithms.Conclusions: Separate-and-conquer rule induction in combination with weighting scheme is an effective technique for building rule-based models of survival data which, according to predictive accuracy, are competitive with tree-based representations.

Abstract
Sarcoidosis may affect lung function, working ability, overall mobility, and daily activity. In the present study we performed an analysis of clinical settings in patients with sarcoidosis to disentangle its influence on daily physical activity (PA). PA assessment (number of steps per day, daily energy expenditure) was performed by accelerometry during consecutive 7 days after discharge from hospital. Thirty patients with sarcoidosis, aged 46.4 ± 10.5, were enrolled in the study. Clinical data (age, gender, steroid consumption, weight, and comorbidities), lung function tests (forced expiratory volume in one second - FEV1, forced vital capacity - FVC, and lung diffusion for carbon monoxide - DLCO), mobility (6-minute walk test - 6 MWT) and physical performance (oxygen consumption at anaerobic threshold - VO2/AT) were estimated. The mean daily PA (5214 ± 2699 steps/day) and VO2max (22.3 ± 7.0 ml/kg/min) were lower when referenced to the age-group predicted values. A significant greater daily PA was observed in sarcoidosis patients without comorbidities compared with those having more than two comorbidities (p = 0.046). No association was found between steroid use, lung function, and 6MWT. Daily PA was associated with patients aerobic efficacy and VO2max (r = 0.38, p < 0.04). The findings demonstrate a significant influence of comorbidities on sarcoidosis patients' exercise tolerance and daily PA. Special treatment considerations, including the potential impact of comorbidities, may help optimize exercise regimes, link physical activity with health, and prevent sarcoidosis complications.

Abstract
Scientific reports underscore the importance of measuring the health-related quality of life in sarcoidosis patients. The present study seeks to define how sarcoidosis patients' quality of life, daily physical activity, and physical performance are related to each other. Seventeen patients (mean age 46.8 ± 8.8 years) suffering from sarcoidosis completed the following questionnaires: the fatigue assessment scale (FAS), the quality of life scale (SF-36 questionnaire), and the Borg dyspnea scale. Physical activity (PA) was assessed using accelerometry. Respiratory function, consisting of forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory volume in one second as a percentage of vital capacity (FEV1/%FVC), and diffusing capacity of the lungs for carbon monoxide (DLCO), were assessed. In addition, performance in 6-min walk test (MWT), aerobic capacity assessed from maximal oxygen uptake (VO2max), and the metabolic equivalent of task (MET) were evaluated. We found that daily PA (4566 ± 2378 steps/day) and VO2max (21.8 ± 5.9 ml/kg/min) were lower in sarcoidosis patients than the known predicted values in healthy age-matched individuals. There were significant inverse associations between the FAS score and 6MWT (r = -0.62; p < 0.01), and between SF-36 score and 6MWT (r = -0.55; p < 0.03). In contrast, SF-36 scores associated with fatigue and dyspnea scores (r = 0.72; p < 0.001 and r = 0.85; p < 0.001). These findings imply that sarcoidosis patients are less active compared with healthy subjects. The FAS and SF-36 scales seem to be effective tools for assessing the severity of fatigue in sarcoidosis patients.

Abstract
Temperature dependent 55Mn NMR study of Sm0.55Sr0.45MnO3 is reported. Previous bulk magnetization measurements have shown that below T C ~ 125 K the sample is ferromagnetic metallic (FMM) and above TC it is charge ordered and insulating. In present report, we show that from zero-field NMR a single line double-exchange (DE) signal is observed at temperatures up to 139 K, which is due to a presence of FMM clusters also above T C. The intensity of the DE line follows the temperature dependence of the magnetization measured at 0.01 T. When a magnetic field up to 2 T is applied at 139 K (i.e. 14 K above T C), a strong increase in NMR intensity of the DE line is observed indicating that content of FMM regions increases. This reveals that metallicity is induced in the material by the applied magnetic field and explains the observed colossal magnetoresistance (CMR) effect at the microscopic level. The observation agrees with previous results, which confirm that the percolation of the FMM clusters is responsible for the CMR effect. The shift of the resonant frequency in the applied field is three times smaller compared to decrease expected from gyromagnetic ratio, which indicates an antiferromagnetic coupling between the FMM clusters.

Abstract
The aim of this study was to examine the association of single-nucleotide polymorphisms (SNPs) in the gene encoding ficolin-2 protein (FCN2 gene) at positions -986 (rs17514136), -602 (rs3124953), and -4 (rs3124952) with dental caries in Polish children. Two hundred and sixty Polish Caucasian children aged 15 years were enrolled in this study: 82 with "higher" caries experience (DMFT >5) and 178 with "lower" caries experience (DMFT ≤5). In addition, subjects with caries experience (DMFT ≥1) and caries-free subjects (DMFT = 0) were compared. FCN2 SNPs were genotyped with PCR-RFLP methods. There were no significant differences in the genotype, allele, or haplotype distributions in 3 analyzed SNPs of the FCN2 gene between children with "higher" and those with "lower" caries experience as well as between children with caries experience and caries-free children. In conclusion, we did not find any association of FCN2 promoter polymorphisms at positions -986, -602, and -4 with dental caries in Polish children.

Abstract
Elaboration of cocoa syrups by the use of modified starches such as acetylated distarch adipate (ADA) and oxidised starch (OS) were described and analysed the influence of different amounts of ADA and OS on physical and sensory properties of cocoa syrups. The sensory, textural and rheological properties of syrups produced in the laboratory conditions were compared to the properties of commercially produced ones. The quantity of modified starch added affected textural and rheological properties of syrups. All analysed syrups showed non-Newtonian, pseudoplastic flow and thixotropy. Values of yield stresses, viscosities of Casson, and consistency coefficients of syrups prepared in laboratory conditions increased with an increase in the addition of modified starches.

Abstract
BACKGROUND Recent meta-analyses of resting-state networks in major depressive disorder (MDD) implicate network disruptions underlying cognitive and affective features of illness. Heterogeneity of findings to date may stem from the relative lack of data parsing clinical features of MDD such as phase of illness and the burden of multiple episodes. METHOD Resting-state functional magnetic resonance imaging data were collected from 17 active MDD and 34 remitted MDD patients, and 26 healthy controls (HCs) across two sites. Participants were medication-free and further subdivided into those with single v. multiple episodes to examine disease burden. Seed-based connectivity using the posterior cingulate cortex (PCC) seed to probe the default mode network as well as the amygdala and subgenual anterior cingulate cortex (sgACC) seeds to probe the salience network (SN) were conducted. RESULTS Young adults with remitted MDD demonstrated hyperconnectivity of the left PCC to the left inferior frontal gyrus and of the left sgACC to the right ventromedial prefrontal cortex (PFC) and left hippocampus compared with HCs. Episode-independent effects were observed between the left PCC and the right dorsolateral PFC, as well as between the left amygdala and right insula and caudate, whereas the burden of multiple episodes was associated with hypoconnectivity of the left PCC to multiple cognitive control regions as well as hypoconnectivity of the amygdala to large portions of the SN. CONCLUSIONS This is the first study of a homogeneous sample of unmedicated young adults with a history of adolescent-onset MDD illustrating brain-based episodic features of illness.

Abstract
OBJECTIVES Addictive sexual behaviours are gaining more and more attention from researchers. There are actually 25 different questionnaires for assessing the level of loss of control over sexual. The main aim of this work was to make such an adaptation of the Sexual Addiction Screening Test-Revised (SAST-R; the most popular and questionnaire). behaviours (LoCoSB). None of them have been adapted and validated in a Polish language version. METHODS For the purpose of psychometric features examination and validation of the Polish version of SAST-R (SAST-PL-M), we recruited 116 heterosexual men receiving psychological treatment due to LoCoSB and meeting the criteria for hypersexual disorder. The control group consisted of 442 heterosexual males having never looked for any psychological or psychiatric help due to LoCoSB. RESULTS SAST-PL-M has high reliability (Cronbach's alpha = 0.904) and good filtering characteristics for identification of people who are potentially experiencing difficulty with control over sexual behaviours (the ROC curve for a threshold of 5 out of a maximum 20 points is characterised by a sensitivity of 99.1% and a specificity of 78.3%). CONCLUSIONS SAST-PL-M can be used as an efficient screening test for symptoms of LoCoSB in clinical and research setups. Results below 5 points indicate a high probability of no problems, while more than 5 points can indicate the need for additional clinical interviews. SAST-PL-M results may be successfully referred to the results of SAST-R when used with heterosexual male populations for research purposes.

Abstract
A new concept of using thin-layer chromatography to sample preparation for the quantitative determination of solute/s followed by instrumental techniques is presented Thin-layer chromatography (TLC) is used to completely separate acetaminophen and its internal standard from other components (matrix) and to form a single spot/zone containing them at the solvent front position (after the final stage of the thin-layer chromatogram development). The location of the analytes and internal standard in the solvent front zone allows their easy extraction followed by quantitation by HPLC. The exctraction procedure of the solute/s and internal standard can proceed from whole solute frontal zone or its part without lowering in accuracy of quantitative analysis.

Abstract
BACKGROUND AND AIM Many studies show high prevalence of affective disorders in obese patients. Affective temperament is a subclinical manifestation of such conditions. The 5-HTT gene encoding the serotonin transporter may be involved in both mood and eating dysregulation. The aim of this study was to investigate the influence of a polymorphism in the 5-HTT gene on affective temperament types, depressive symptoms and Body Mass Index (BMI) in obese patients. METHODS This study involved 390 patients (237 females, and 153 males) with obesity. The TEMPS-A questionnaire, Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HDRS) were used to evaluate affective temperaments and prevalence of depression. DNA was obtained for serotonin transporter gene-linked polymorphism (5-HTTLPR) genotyping. RESULTS In obese patients S/S genotype was associated with depressive and L/L with cyclothymic temperament. Subjects with L/L genotype presented significantly higher BMI and greater intensity of depressive symptoms in BDI and HDRS. Females scored higher in anxious and depressive, while males in hyperthymic, cyclothymic and irritable temperaments. Females scored higher in BDI (subjective depression) while males in HDRS (objective depression). LIMITATIONS TEMPS-A, BDI and HDRS are frequently used in studies on affective disorders. However, these methods do not examine all dimensions of mood and personality. CONCLUSIONS In obese patients S allele of 5-HTTLPR was associated with development of depressive temperament while L allele corresponded with greater obesity and prevalence of depression. Different mechanisms may be involved in manifestation of depression in males and females with obesity.

Abstract
Aim: The purpose of this study was to analyse vaccine refrigerator and vaccine management in primary care and to identify physician- and practice-related influencing factors. Background: Adequate cooling of vaccines in a temperature range of 2-8°C is essential to assure vaccine effectiveness. Studies from various countries have demonstrated cooling chain problems. We surveyed general practitioners about the quality of their vaccine refrigerator and vaccine management and aimed at identifying physician- and practice-related influencing factors. Methods: A cross-sectional, web-based questionnaire survey was performed among 3 physician populations in primary care: a 10% random sample of general practitioners (n=954), all teaching physicians of the Universities Duisburg-Essen (n=221) and Halle-Wittenberg (n=92). Surveyed were items on the following 6 aspects: (1) responsibilities within practice teams, (2) vaccine ordering and storing, (3) criteria for the vaccine pre-selection, (4) stocking system inside the refrigerator, (5) wrapping, and use of stocking boxes, (6) refrigerator and temperature control. The quality indicator "comprehensive refrigerator management" was defined to include 4 aspects: (1) separate refrigerator, (2) written temperature documentation (temperature-logbook), (3) regular storage control (wrapping, temperature and expiration date), and (4) storage in original wrappings. Results: A total of 278 physicians participated in the survey (22%). Of these, 80% had a separate refrigerator, 52% reported written temperature documentation, 93% documented regular storage control addressing vaccine wrappings, temperature and expiration dates, and 95% reported vaccine storage in original card box wrappings. A "comprehensive refrigerator management" was realised by 42% of the practices. This indicator was reached more frequently by practices with 3 or more physicians (p=0.01) and those with an additional qualification in travel medicine (p=0.036). Conclusion: Our survey showed good results for most aspects of the refrigerator and vaccine management but room for improvement with regard to temperature documentation.

Abstract
UNLABELLED The study was undertaken to verify the antimicrobial activity of Lavandula angustifolia hydrosols in moisturizing body gels. The inhibition efficacy of four lavender hydrosols (obtained from fresh or dry herbs or flowers) was tested against Staphylococcus aureus ATCC 6538, Escherichia coli ATCC 1627, Candida sp. ŁOCK 0008 and Aspergillus niger ATCC 16404 in compliance with the standards of the European Pharmacopoeia Commission. Although the tested hydrosols did not express any remarkable antimicrobial action when tested via the macrodilution method, they show preservative activity in cosmetic preparations. Criterion A for fungi was fulfilled for the cosmetic formulation containing dried flower hydrosol (reduction of the inoculum by two logarithmic units within 14 days with no increase up to the 28th day) and Criterion B for bacteria E. coli and Staph. aureus (reduction of the inoculum by three logarithmic units within 14 days with no increase up to the 28th day). The fresh herb lavender hydrosol in the cosmetic formulation was regarded as the second one effectively satisfying Criterion B for bacteria, but its activity against fungi was below the acceptance value set out in the official regulations. Lavender hydrosols used as a replacement for water phase in cosmetics may contribute to maintaining microbiological stability of cosmetic formulations. SIGNIFICANCE AND IMPACT OF THE STUDY The presented research proved antimicrobial activity of hydrosols obtained from fresh or dried Lavandula angustifolia herbs or flowers in moisturizing body gel. The study shows the usefulness of lavender hydrosols as a natural, ecologically friendly component of cosmetics with potential preservative activity in formulations. Hydrosols are commonly regarded as waste in the production of essential oils. The use of lavender hydrosols in the cosmetic industry as a replacement for water phase in cosmetics may not only result in expenses reduction for chemical stabilizers and preservatives but also in substantial decrease in sewage disposal.

Abstract
The aim of the retrospective study were to estimate the prevalence of Candida glabrata in liver and kidney transplant recipients compared to patients with short bowel syndrome receiving chronic total parenteral nutrition and relevance of the polymerase chain reaction melting profile (PCR MP) method for Candida glabrata strains differentiation. C. glabrata clinical strains isolated from patients were identified by using standard mycological procedures. The analysis of genetic relatedness of the isolated strains was conducted using the PCR MP method. The prevalence of C. glabrata comprised 29% of all episodes of fungal colonization and infection in solid organ transplant recipients, and 54% of those in hospitalized patients receiving long-term total parenteral nutrition. Among 78 isolates obtained from 55 solid organ transplant recipients and 2 organ donors, 44 different C. glabrata PCR MP fingerprints were observed. Forty-seven organ recipients and one organ donor carried unique C. glabrata strains. Among 37 isolates obtained from 31 patients receiving long-term TPN, 8 different PCR MP profiles of C. glabrata strains were observed. Two patients carried unique C. glabrata strains. Most of the C. glabrata colonization and infections in solid-organ transplant recipients were caused by endogenic strains. Most of the C. glabrata colonization and infections in hospitalized patients receiving long-term total parenteral nutrition could result by patient-to-patient transmission. The results showed that the PCR MP technique is a good discriminatory method for genotyping for C. glabrata strains.

Abstract
In the past years opportunistic fungal infections have seriously increased, mainly in immunocompromised patients. The aim of the study was to determine the prevalence of yeast-like fungi in invasive candidiasis and to estimate its susceptibility to chosen antifungal agents. One hundred and sixty strains of yeast-like fungi were cultured from various clinical material: samples from lower respiratory tract, blood, the peritoneal cavity and others. The susceptibility tests were established according to the quantitative E-test method. The Candida genus represented the main etiological factor of invasive candidiasis. The predominant species were: C. glabrata (71/160), C. albicans (34/160), C. krusei (17/160), C. tropicalis (14/160). All tested strains were the most resistant to itraconazole. Candida glabrata presented the 100% susceptibility to amphotericin B and caspofungin and was the least susceptible to itraconazole, posaconazole and voriconazole. Candida albicans was the most susceptible species to all antymicotics.
