    Opis:
    Utilization of various amino acids and carbohydrates by heterotrophic bacteria isolated from a sandy beach in Sopot, Poland, southern Baltic Sea coast, was determined. The most intensive growth of bacteria was observed in the presence of amino acids, while carbohydrates were utilized less actively. Differences in the utilization of individual amino acids and carbohydrates by bacteria have been determined. The highest capability to assimilate amino acids and carbohydrates was observed in bacterial strains isolated from the middle part of the studied beach. No major differences were determined in the intensity of assimilation of the tested compounds by bacteria isolated from the surface and subsurface sand layers. Bacterial utilization of amino acids and carbohydrates depended on the chemical structure of those compounds.
    W pracy przedstawiono wyniki badań dotyczących wykorzystania w procesach metabolicznych aminokwasów i cukrów przez bakterie heterotroficzne wyizolowane z plaży morskiej południowego Bałtyku. Stwierdzono, że bakterie wykazywały znacznie lepszy wzrost w obecności aminokwasów niż cukrów. Najbardziej preferowanymi przez bakterie aminokwasami były kwas asparaginowy i histydyna, a cukrami mannoza i ryboza. Nie stwierdzono różnic w intensywności asymilacji aminokwasów i cukrów przez bakterie wyizolowane z powierzchniowych i podpowierzchniowych warstw piasku. Natomiast wykazano, że poziom przyswajania przez bakterie obu badanych grup organicznych związków niskocząsteczkowych zmieniał się istotnie w płaszczyźnie horyzontalnej plaży morskiej. Szczepy bakterii wyizolowane ze środkowej części plaży charakteryzowały się największa aktywnością metaboliczna wobec testowanych aminokwasów i cukrów. Poziom bakteryjnego wykorzystania aminokwasów i cukrów zależał od ich budowy chemicznej. Najwyższy procent testowanych szczepów bakterii preferował aminokwasy aromatyczne i siarkowe, a spośród cukrów heksozy.

    Opis:
    The objective of the study was to evaluate an efficacy of sows vaccination protocols in the herd with serious problems affecting efficacy of reproduction. The study was performed in a large pig herd with about 1200 sows. Before vaccination against PCV2, farrowing rate in this farm was about 65%. Sows, boar and replacement gilts were immunized using Circovac vaccine (Merial, France) according to producer’s recommendations. Parameters of production were analyzed since 2007 until 2010 in selected batches of sows inseminated at the same weeks of the year (17th, 18th, 19th and 20th) to eliminate seasonal variability. In total, 940 sows were subjected to the study. No significant changes in management during these years were introduced. The applied protocol of sow herd long-term vaccination proved to be very efficient. All measured production parameters: reproduction rate, number of piglets born alive, birth weight of piglets and number of piglets weaned per a litter improved after implementation of immunization program. Moreover, further improvement was observed with vaccination in the following reproduction cycles. The most spectacular effect of vaccination regarded average farrowing rate that increased from 64.76% in control group to 86.93% after basic vaccination. Two years after implementation of vaccination program this parameter reached 93.6%. Number of piglets weaned per sow per a litter improved from 10.31 to 11.74 after one year of vaccination and remained relatively stable through the following year. Simultaneously, the percentage of newborn piglets with birth weight < 1 kg decreased significantly (p < 0.05). To summarize, vaccination against PCV2 influenced positively the insemination rate, number of piglets born alive and weaned per litter as well as birth body weight and percentage of piglets weighing < 1 kg.

    Opis:
    The paper reports on the growth conditions of Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ single crystals in both pure and Yb, Co, Mn doped systems. The crystals were grown by the Czochralski method using an intentional concentration of the above-mentioned ions at a level of 0.5 mol.%. The pure and Mn-doped crystals were found to be highly transparent and clear. The crystals doped with Yb$\text{}_{2}$O$\text{}_{3}$ had a lot of precipitations making them opaque. The Co-doped crystals were purple-blue in colour and highly transparent. The growth of Yb and Co doped Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ crystals was reported for the first time in this paper. Absorption was measured in the range of 200 to 3200 nm, moreover analysis of changes in the absorption spectrum ofγ-irradiated pure and doped Li$\text{}_{2}$B$\text{}_{4}$O$\text{}_{7}$ crystals was performed. Some thermoluminescence properties were measured, e.g. energies and lifetimes of the traps of different charge carriers occurring in the crystals at low temperatures.

    Opis:
    Purpose: Correct foot structure is important due to locomotion and postural stability. The aim of this study was to determine the relationships between morphological foot structure and balance indices in a quiet standing position in women over 65 years of age. Methods: The study included 116 women aged 65-90 years. The mean age was 70.6±8.4 years and BMI 29.1±3.4 m/kg2. The measured indices included postural control while standing on both feet and photogrammetric foot evaluation. An analysis was performed of the selected foot and balance indices. Results: There were no significant differences observed in the feet structure. Certain correlations between some foot indices and the indices of postural control were noted. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis. Conclusions: The differences between the indices and morphological indices for the right and the left foot are not significant, which indicates the proportionate formation of feet in the individual life. The increased differences in the width indices between the right and the left foot lead to balance deterioration. Larger angles of valgity and varus deformity of toes and indices describing the longitudinal arch and transverse front arch of the foot have the greatest impact on the deterioration of balance in the medio-lateral axis.

    Opis:
    Introduction and objective: The aim of the study was to determine the effects of 3-(N-p-isopropoxyphenylsuccinimidomethylamino)-cinnamic acid (IPPSMA-CA – a new succinimide derivative) on the protective action of 4 classical antiepileptic drugs (AEDs): carbamazepine [CBZ], phenobarbital [PB], phenytoin [PHT] and valproate [VPA]), against maximal electroshock (MES)-induced tonic seizures in mice. Materials and methods: Tonic hind limb extension (seizure activity) was evoked in adult male albino Swiss mice by a current (sine-wave, 25 mA, 500 V, 50 Hz, 0.2 s stimulus duration) delivered via auricular electrodes. Acute adverse-effectprofiles of the combination of IPPSMA-CA and 4 classical AEDs (CBZ, PB, PHT and VPA) with respect to motor performance, long-term memory and skeletal muscular strength were measured in the chimney, passive avoidance and grip-strength tests, respectively. Results: IPPSMA-CA administered at 150 mg/kg (i.p.) significantly elevated the threshold for electroconvulsions in mice (p<0.01). IPPSMA-CA at doses of 50 and 100 mg/kg, however, had no significant impact on the threshold for electroconvulsions in mice. Nor did IPPSMA-CA (100 mg/kg) significantly affect the anticonvulsant activity of CBZ, PB, PHT and VPA in the MES test in mice. None of the examined combinations of IPPSMA-CA (100 mg/kg, i.p.) with CBZ, PB, PHT and VPA (at their ED50 values from the MES-induced seizure test) affected motor coordination in the chimney test, long-term memory in the passive avoidance task, and muscular strength in the grip-strength test in mice. This indicates no possible acute adverse effects in animals. Conclusions: IPPSMA-CA elevated the threshold for electroconvulsions in mice in a dose-dependent manner. However, IPPSMA-CA at a sub-protective dose of 100 mg/kg did not affect the anticonvulsant action of various classical AEDs in the mouse MES model. Thus, the combinations of IPPSMA-CA with CBZ, PB, PHT and VPA are neutral from a preclinical viewpoint.
