    Opis:
    Background: UML class diagrams can be automatically validated if they are compliant with a domain knowledge specified in a selected OWL 2 domain ontology. The method requires translation of the diagrams into their OWL 2 representation. Aim: The aim of this paper is to present transformation and verification rules of UML class diagrams to their OWL 2 representation. Method: The analysis of the results of the systematic literature review on the topic of transformation rules between elements of UML class diagrams and OWL 2 constructs. The purpose of the analysis is to present the extent to which state-of-the-art transformation rules cover the semantics expressed in class diagrams. On the basis of the analysis, new transformation rules expressing the semantics not yet covered but expected from the point of view of domain modelling pragmatics have been defined. Results: The first result is the revision and extension of the transformation rules identified in the literature. The second original result is a proposition of verification rules necessary to check if a UML class diagram is compliant with the OWL 2 domain ontology. Conclusion: The proposed transformations can be used for automatic validation of compliance of UML class diagrams with respect to OWL 2 domain ontologies.

    Opis:
    ObjectivesPhysical activity (PA) is important for the prevention and management of numerous diseases and may have a positive effect on ability to work. The study aimed to assess the level of occupational and leisure time PA of soldiers during the COVID-19 pandemic and to explore whether there was a relationship between PA and perceived work ability.Material and MethodsThe study involved 305 men and 68 women who were territorial army soldiers aged 18–55 (M±SD 32.9±9.01). The Seven-Day Physical Activity Recall (SDPAR) and the Work Ability Index (WAI) were used.ResultsThe level of self-reported PA for the studied soldiers was relatively high; 80% of them met the recommendations of the WHO and were characterized by having a good (60%) or excellent (20%) WAI status. The level of occupational PA of male soldiers was higher than the level of leisure time PA, and they indicated higher levels of occupational PA and leisure time PA during the workweek than the weekend.ConclusionsCurrent work ability in comparison to the best in life and work ability related to the physical requirements of the work were positively correlated with leisure time PA. Work ability related to physical requirements was also positively correlated with occupational and total PA, and work ability related to mental requirements was positively correlated with total PA. The study supports the relationship between PA and several aspects of work ability.

    Opis:
    Due to constantly increasing antibiotic resistance of pathogens and participation of the biofilms they make in various types of infections, a development of alternative therapeutic strategies becomes an urgent need. Taking advantage of the biological activity of plant-derived compounds can solve this problem. In this study antimicrobial, including those synergistic with classic antibiotics, and cytotoxic properties of newly-obtained extracts from Vaccinium myrtillus leaves (VLE) and Frangula alnus bark (FBE) were evaluated. Both tested extracts exhibited relevant antistaphylococcal activity (MIC range 0.75-1.5 mg/mL) accompanied by a relativly low cytotoxic effect on mammalian cells (BI > 1). Phytochemical analysis of the extracts tested showed a high total content of phenolic compounds with the predominance of hydroxycinnamic acids in VLE and hydroxybenzoic acids and flavanols in FBE. Widely described in the literature antimicrobial properties of phenolics were probably connected with the biological activity of the extracts tested. We also report that the presence of VLE or FBE at sub-MIC concentrations enhances biocidal potential of vancomycin and linezolid. Therefore, we are considering a possibility of an alternative therapy for local infections caused by S. aureus by combining classic antibiotics with plant-derived extracts.

    Opis:
    Introduction and objective. The assessment of physical activity during pregnancy is crucial in perinatal care and it is an important research topic. Unfortunately, in Poland there is a lack of one commonly accepted questionnaire of physical activity during pregnancy. The aim of this study was to adapt the Pregnancy Physical Activity Questionnaire (PPAQ) to Polish conditions and assess the reliability of its Polish version (PPAQ-PL). Materials and method. The PPAQ was translated from English into Polish and its reliability tested. 64 correctly completed (twice, one week apart) questionnaires were qualified for analysis. Test-retest reliability was assessed using Intraclass Correlation Coefficient (ICC). Results. As a result of the adaptation and psychometric assessment, in the Polish version of the questionnaire the number of questions was reduced from 36 to 35 by removing the question concerning ‘mowing lawn while on a riding mower’. The ICC value for total activity was 0.75, which confirms a substantial level of reliability. The ICC values for subscales of intensity ranged from 0.53 (light) – 0.86 (vigorous). For subscales of type, ICC values ranged from 0.59 (transportation) – 0.89 (household/caregiving). Conclusions. The PPAQ-PL can be accepted as a reliable tool for the assessing physical activity of pregnant women in Poland. Information obtained using the questionnaire might be helpful in monitoring health behaviours, preventing obesity, as well as designing and promoting physical activity programmes for pregnant women.

    Opis:
    The objective was an assessment of the impact of Leonurus cardiaca L. extract (LCE) and ursolic acid (UA) on the adhesive properties of Staphylococus aureus NCTC 8325 strain, expressing virulence factors important in the pathogenesis of infective endocarditis. The adhesion and biofilm formation of bacteria cultured in the presence of subinhibitory concentrations of LCE or UA on the abiotic surface or covered with fibrinogen, fibronectin or collagen, were evaluated. Inhibitory effects of LCE and UA on staphylococcal adherence to both types of surface were demonstrated. This, in the case of UA, resulted in a significant reduction of biofilm formation.

    Objectives This study evaluates the effect of a 3-month calorie restriction (CR) without snacking on the anthropometric parameters, Homeostatic Model Assesment of Insulin Resistance (HOMA-IR), and lipid profiles of female office workers with overweight or obesity, whose physical activity was limited during the COVID-19 pandemic lockdown. Material and Methods Forty-eight women aged 20–38 years (28.9±5.24) with low physical activity levels were divided into a non-snacking (NS) group (N = 21) and a snacking (S) group (N = 27) prior to the dietary intervention. Their daily energy intake during the intervention was lowered by 30% compared with the baseline level, and the proportion of polyunsaturated fatty acids and fiber in their diet was increased (to >30 g/day). The proportion of saturated fatty acids and simple carbohydrates was also reduced. The study participants were assessed at the baseline and post-intervention for anthropometric variables (body weight, body fat percentage BMI, waist circumference, hip circumference, waist-to-hip ratio) and the concentrations of insulin, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Moreover, the values for HOMA-IR, the atherogenic index of plasma (AIP), and the ratios of TC/HDL-C, TG/HDL-C, and LDL-C/HDL-C were calculated. Results All anthropometric parameter values obtained post-intervention were lower than the baseline in both groups. The serum insulin concentration and HOMA-IR decreased respectively by an average of 6% and 25% in the NS group and 37% and 45% in the S group. The lipid profiles of all participants improved significantly, with the LDL-C concentration showing a more promising trend in the S group (decrease by 27%) than in the NS group (17%). Conclusions The study showed that CR improved the anthropometric parameters, HOMA-IR index, and lipid profiles of all participants.

    Opis:
    Background: Head and neck neoplasms stand for 6% of all malignant neoplasms worldwide. Chemotherapy has limited use due to the biological properties of the tumor (in the majority of cases moderately and poorly differentiated squamous cell carcinoma). The fundamental molecule used in treatment is cisplatin and its derivates, that can be associated with fluorouracil. The new chemotherapeutic agents are not in common use during the treatment of head and neck malignancies. However, the use of low molecular weight complexes Pd (II) carries the potential of being more effective in therapy. Material and Methods: Fifty-one patients, 30 men and 21 women (aged 52.9 ± 12.1 years) with head and neck cancer were included in the study. Fifty-one healthy subjects, 31 men and 20 women, (aged 54.1 ± 14.7 years) years formed the control group. Antioxidant enzymes, superoxide dismutase, and catalase activities in erythrocytes were examined. Results: An increased level of antioxidant enzymes was seen in the blood samples from patients with head and neck cancer after incubation with Pd (II) complex. In the group we obtained a statistically significant result p = <0.001. Discussion: That project may contribute to the development of new, more efficient head and neck cancer treatment strategies. In our opinion, the results can be used in the future to develop a valuable prognostic marker of the disease. This is important because the initial phase of cancer is asymptomatic. The search for factors involved in pathogenesis translates into economic benefits and makes therapy more effectiveness through the reduction of treatment expenses.
