Opis:
Physical effort can elicit differential adaptive changes in the tissues of trained versus untrained rats. Proteolytic activity in the extracellular matrix could be engaged in such adaptation due to its influence on the elasticity of tissues. The effects were investigated of a single physical effort on the activity of elastase, cathepsin K, and plasmin in the skeletal muscles, heart muscles, and aortas of untrained (UT, n=30) and trained (T, n=30) rats. T rats underwent 6 weeks of endurance training. After the last training session, T and UT rats were divided randomly into 3 subgroups. Ten rats from each group (Tpre, n=10) and (UTpre, n=10) were sacrificed. The other 20 rats from each group performed 60 min. of aerobic exercise and were sacrificed immediately post exercise (T0h, n=10; UT0h, n=10) or 3h later (T3h, n=10; UT3h, n=10). Enzyme activity was measured fluorometrically. Cathepsin K and plasmin activity increased in the soleus muscles of UT0h versus UTpre, plasmin activity increased also in UT3h versus UTpre. Elastase, cathepsin K and plasmin activity increased in the heart muscles of T0h and T3h versus Tpre. No aortic differences were observed. Thus, a single bout of physical effort elicited different responses in tissues of T versus UT rats. Increased proteolytic enzyme levels in muscles could influence tissue remodeling. Unchanged aortic cathepsin K levels may help prevent aortic remodeling and neointima formation.

Opis:
Introduction and objective. One of the main factors determining the burden of breast cancer is the effectiveness of measures taken to combat this cancer including urban-rural differences. The aim of the study was to analyse the differences in breast cancer incidence and disease stage distribution among urban and rural women in the Świętokrzyskie Province as a part of a strategy for breast cancer control. Materials and method. The study of disease stage distribution included 483 female residents of Świętokrzyskie Province who were diagnosed in 2013 with invasive breast cancer, and reported to Świętokrzyskie Office for Cancer Registration. Urban-rural differences in breast cancer incidence in 2002–2013 were presented using Range Ratio (RR). Changes in incidence trends in urban and rural areas were analysed using joinpoint models. Annual Percentage Change (APC) of the rates was calculated for each time trend. Results. Breast cancer incidence rate in the urban female population was higher than in rural women with RR, amounting to 1.43. However, the analysis of trends showed that the pace and direction of change were developing negatively among inhabitants of rural areas. In 2002–2013, in rural women, the age-standardized rate (ASR) values increased by 2.8% per year (p<0.05). The course of ASR trends showed statistically significant urban-rural differences (p=0.004). Analysis of urban-rural differences in disease stage distribution revealed a non-significantly higher proportion of cases with localised stage in urban than in rural areas, amounting to 51.0% and 43.9%, respectively. Conclusions. Existing health inequalities indicate the need to intensify activities in rural areas and should be the starting point for making key decisions in combating breast cancer.

Opis:
Introduction and objective. The timings of Fraxinus and Betula flowering and pollen release overlap, which may cause increased allergic reactions in sensitive people. The aim of the present study was to characterize Fraxinus pollen seasons in Lublin (central-eastern Poland) and to identify meteorological factors that most determine the occurrence of airborne pollen of this taxon, as well as obtain forecast models for the basic characteristics of the pollen season. Materials and method. The study was conducted in Lublin during the period 2001–2016, employing the volumetric method. The seasons were compared by PCA (Principal Component Analysis). To determine relationships between meteorological conditions and the pattern of pollen seasons, regression analysis was used. Data for the period 2001–2015 were used to create forecast models by applying regression analysis, while the 2016 data served to verify these models. Results. Season end date and seasonal peak date were characterized by the lowest variation. The biggest differences were found for peak value and total annual pollen sum. The average dates of occurrence of ash pollen grains in the air of Lublin were between 13 April 13 – 3 May 3, whereas, on average, the pollen peak date occurred on 23 April. The factor loading values for the PC1 variable indicate that it is most strongly correlated with peak value and total pollen sum, while the PC2 variable correlated with the pollen season start date and season duration (a negative correlation). Regression models were developed for the following pollen season characteristics: season start, end and duration, seasonal peak date, and total annual pollen sum. Conclusions. The fit of the forecast models was at the level of 62–94%. Analysis of the data showed that weather conditions mainly in February were important factors controlling the Fraxinus pollen season.
