    Opis:
    The objective of the study was to test the research hypothesis that the surface area of the medullary bone is correlated with other indicators of body condition. The study also focused on identification of potential differences in and with carcass weight fat parameters and carcass weight between forest and field ecotypes of roe deer. The area of the medullary cavity was measured using DIRA 200 software. Metacarpal bone III+IV, proximal phalanges III and IV, and middle phalanges III and IV were measured as well. The study included 38 female European roe deer (Capreolus capreolus) aged 3-5 years. The results revealed a statistically significant negative correlation between the surface area of the medullary cavity in metacarpal bone III+IV and the kidney fat index KFI (rs = −0,483; P < 0,05) and the weight of the perirenal adipose tissue (rs = −0,362; P < 0,05). No correlation was shown between the area of the medullary cavity of metacarpal bone III+IV and the doe carcass weight (rs = 0,093; ns). The size of the medullary cavity is an anatomical parameter that is not susceptible to cyclical changes in environmental conditions. The study showed that it is independent of body weight and determines the amount of bone marrow and hence the amount of accumulated fat reserves. We believe that, alongside biometric measurements, the surface area of the medullary cavity can be a good parameter for assessment of the individual quality of roe deer and for comparison of populations.

    Opis:
    Filtering nonwovens produced with melt-blown technology are one of the most basic materials used in the construction of respiratory protective equipment (RPE) against harmful aerosols, including bio- and nanoaerosols. The improvement of their filtering properties can be achieved by the development of quasi-permanent electric charge on the fibres. Usually corona discharge method is utilized for this purpose. In the presented study, it was assumed that the low-temperature plasma treatment could be applied as an alternative method for the manufacturing of conventional electret nonwovens for the RPE construction. Low temperature plasma treatment of polypropylene nonwovens was carried out with various process gases (argon, nitrogen, oxygen or air) in a wide range of process parameters (gas flow velocity, time of treatment and power supplied to the reactor electrodes). After the modification, nonwovens were evaluated in terms of filtration efficiency of paraffin oil mist. The stability of the modification results was tested after 12 months of storage and after conditioning at elevated temperature and relative humidity conditions. Moreover, scanning electron microscopy and ATR-IR spectroscopy were used to assess changes in surface topography and chemical composition of the fibres. The modification of melt-blown nonwovens with nitrogen, oxygen and air plasma did not result in a satisfactory improvement of the filtration efficiency. In case of argon plasma treatment, up to 82% increase of filtration efficiency of paraffin oil mist was observed in relation to untreated samples. This effect was stable after 12 months of storage in normal conditions and after thermal conditioning in (70 ± 3)°C for 24 h. The use of low-temperature plasma treatment was proven to be a promising improvement direction of filtering properties of nonwovens used for the protection of respiratory tract against harmful aerosols.

    Opis:
    In gilts, the period of early pregnancy occurring from the time of fertilization to the beginning of implantation is sensitive to any environmental disruptions, including an unbalanced diet of a future mother. Previously, we found that due to the undernutrition in gilts during this period, the endocrine intrauterine microenvironment and DNA methylation in the uterus have been changed. These distortions may diminish the success of pregnancy. In this study we focused on the influence of a restricted diet used in gilts during the first days of pregnancy on their biochemical and haematological parameters in peripheral blood. The applied restrictive diet vs. normal diet covered only 70% of the nutritional demands of early pregnant gilts. Normal (n = 4 gilts) or restrictive (n = 5 gilts) diets were used from the day of the first signs of the estrus until day 9 of pregnancy and biochemical and haematological parameters in blood plasma were determined during peri-implantation period, e.g. on days 15 to16 of pregnancy. In restrictive vs. normal fed gilts significantly lower plasma phosphorus, calcium and total cholesterol as well as the tendency to increasing concentrations of triglicerydes and asparate aminotranserase were found. Haematological parameters did not differ between the studied gilts. Thus, it seems that the availability of nutritional factors became suboptimal in restrictively fed early pregnant gilts. Even short-lasting undernutrition of females during the peri-conceptional period may cause a disruption of biochemical homeostasis during the peri-implantation period and probably affect the success of pregnancy.
