    Opis:
    Dużym problemem w implantologii są infekcje pooperacyjne. Infekcje w dużej mierze są wynikiem adhezji mikroorganizmów do powierzchni implantów oraz tworzeniem na ich powierzchniach biofilmu – kompleksu mikroorganizmów osadzonych na stałe do podłoża. W ostatnich latach wiele prac badawczych dotyczy wytworzenia biomateriałów o właściwościach antybakteryjnych. Próbuje się wytworzyć na powierzchni implantów powłoki, które zmniejszają zdolności adhezji oraz trwałego przyczepienia mikroorganizmów i rozwoju biofilmu. Celem pracy były badania strukturalne próbek na bazie tytanu z dodatkiem srebra, które miałyby właściwości antybakteryjne. Wyniki wskazują na możliwość tworzenia takich spieków metodami metalurgii proszków o jednorodnej strukturze i dobrych właściwościach biologicznych.
    The main problem in implantology are postsurgical infections. Infections are a result of the adhesion of microorganisms to the surface of the implant and the formation of biofilm on their surfaces - the complex of microorganisms attached to a solid substrate. In the last few years many research were directed to the preparation of biomaterials with antibacterial properties. Scientists are trying to produce the implant surface coatings that reduce the adhesion capacity and permanent attachment of microorganisms and biofilm development. The aim of this research work was to investigate the structural samples based on titanium with silver, which would have antibacterial properties. The results indicate the possibility of the formation of such sintered powder metallurgy methods of homogeneous structure and good biological properties.

    Opis:
    Przy wykorzystaniu metod metalurgii proszków otrzymano szereg materiałów spiekanych na bazie tytanu – potencjalnych biomateriałów, bez toksycznych dodatków glinu i wanadu. Wykonano badania właściwości mechanicznych otrzymanych materiałów. Badano stopy tytanu: Ti-15Mo-2,8Nb i Ti-7,5Mo-2Fe oraz materiały kompozytowe na bazie tytanu z dodatkami 10% grafitu. Wyniki badań wytrzymałościowych wskazują, że otrzymane biomateriały charakteryzują się dobrymi właściwościami mechanicznymi. Materiały posiadają odpowiednią wytrzymałość na ściskanie i jednocześnie niskie współczynniki sprężystości, co jest bardzo ważne w przypadku materiałów do zastosowań biomedycznych.
    With the use of powder metallurgy methods, a number of titanium-based sintered materials were obtained without toxic additives of aluminium or vanadium – potential biomaterials. Experiments on mechanical properties of the obtained materials were carried out. Ti-15Mo-2.8Nb and Ti-7.5Mo-2Fe alloys, as well as titanium-based composite materials with 10% of graphite added, were tested. The results of strength tests indicate that the obtained biomaterials are characterised by good mechanical properties. The materials are appropriately resistant to compression and yet they have low modulus of elasticity, which is very important in the case of materials for biomedical application.

    Opis:
    Wśród zagadnień biotribologii jednym z najczęściej pojawiających się problemów jest wydłużenie trwałości endoprotez stawów. Konieczność zapewnienia korzystnych parametrów tarciowych przy zachowaniu wymogów biozgodności implantów wymusza poszukiwanie nowych rozwiązań. W pracy przedstawiono koncepcję węzła tarciowego endoprotezy stawu biodrowego opartego na pracy samosmarnego łożyska porowatego. Panewka z warstwą porowatą, wykonaną z porowatego spieku ze stali 316L, powinna zapewnić niskie współczynniki tarcia i małe zużycie elementów współpracujących. Badania przeprowadzono na symulatorze tarcia stawu biodrowego. W celach porównawczych wykonano także analogiczne testy dla tradycyjnych panewek polietylenowych. Ocenę zużycia panewek przeprowadzono zgodnie z normą ISO 14242-2. Badania eksperymentalne potwierdziły słuszność koncepcji porowatego łożyska endoprotezy stawu biodrowego.
    One of the most common among the biotribological issues is elongation of joint endoprosthesis durability. Necessity to ensure favourable friction parameters along with the implants biocompatibility requirements forces search for new solutions. The new conception of tribological system of hip joint endoprosthese, based on the idea of porous selflubricating bearing, was presented in this work. Hip joint cup with porous layer made of porous sintered 316L steel should ensure low friction coefficient as well as low wear of working elements. Research were undertaken on hip joint friction simulator. Similar tests were taken for traditional polyethylene cup for comparison. Wear assessment were led in accordance with ISO 14242-2. Experimental research confirmed legitimacy of the conception of porous hip joint bearing.

    Opis:
    Magnetic and structural properties of EuS-SrS semiconductor multilayers were studied by SQUID and magneto-optical Kerr effect magnetometry techniques and by X-ray diffraction method. The multilayers composed of monocrystalline, lattice matched ferromagnetic EuS layers (thickness 35-50Å) and nonmagnetic SrS spacer layers (thickness 45-100Å) were grown epitaxially on KCl (001) substrates with PbS buffer layer. Ferromagnetic transition in EuS-SrS multilayers was found at the Curie temperature T$\text{}_{c}$=17 K. The multilayers exhibit only weak in-plane magnetic anisotropy with [110] easy magnetization axis. Coercive field of EuS-SrS multilayers shows a linear increase with decreasing temperature. Magneto-optical mapping of magnetic hysteresis loops of the multilayers revealed good spatial homogeneity of their magnetic properties.

    Opis:
    This paper attempts to study the dynamics of apoptosis of granulocytes and lymphocytes in peripheral blood in rabbits infected with haemagglutinating (Vt97, Triptis, Hartmannsdorf) and non-haemagglutinating (Pv97, 9905 RHDVa) antigenic variants of the RHD virus. The pathogenicity of those antigenic variants was also assessed by recording the mortality of the infected animals. The animals were infected with antigenic variants and blood was sampled at hour 0,4,8,12,24,36 p.i. and the percentage of apoptotic granulocytes and lymphocytes was measured with the use of flow cytometry. The results of the study showed that apoptosis is included during RHDV infection, as the number of apoptotic granulocytes and lymphocytes increases throughout the experiment; depending on the antigenic variant, apoptosis joins in at 4-8-12 h p.i. and lasts until 24-36 h p.i. Furthermore, the mortality of rabbits infected with the examined strains of RHD virus varied from 30% to 100%. This study performed for the first time in this manner, indicates the importance of apoptosis during infection with the RHD virus.

    This paper describes a model of cell death, called autophagy, one among other typical and atypical processes of cell death. This phenomenon is present in the organism, from conception until death, and is conditioned by many genes of ATG family, or mTOR kinase and specific proteins, like BNIP3. This process plays a very important role not only in physiological functions of the organism but also in pathological, such as Alzheimer or Huntington disease, as well as diseases caused by viruses.

    Opis:
    The aim of the study was to establish if haemagglutination of rabbit haemorrhagic disease virus (RHDV) affects haematological picture of peripheral blood in rabbits and the pathogenicity of the virus. The study analyzed white and red blood cell picture in rabbits experimentally infected with two non-haemagglutinating (HA-) RHDV strains (Frankfurt and Asturias) and one strain with variable haemagglutination capacity (HA+/−) (Hagenow). Studies with HA− and HA +/− are rare and relate only to 4 HA− strains (2 RHDV: BLA and Rainham; 2 RHDVa: Pv97 and 9905) and 1 HA+/− RHDV strain: ŻD, where less changes in haematological indices and less pathogenicity were observed. We found that changes caused by HA− Frankfurt strain were related to the number of neutrophils and thrombocytes, while in HA− strain Asturias, in thrombocytes and leukocytes. Changes evoked by HA+/− Hagenow strain pertained to the number of eosinophils, thrombocytes, leukocytes, monocytes, and concentration of hemoglobin. Mortality caused by the Frankfurt strain was 100% between 36 and 48 h post infection (p.i.), while that caused by Asturias strain was 100% between 24 and 36 h p.i., and that observed in case of Hagenow strain was 90% between 36 and 48 h p.i. The changes in haematological picture caused by the HA− and HA+/− RHDV strains were less intensive than those found in case of the HA+ RHDV strains, which cannot be confirmed for pathogenicity, and is not in line with the existing hypothesis suggesting higher pathogenicity in HA+ viruses.

    Opis:
    The aim of this study was to determine the differences in immunological response of animals infected with different antigenic variants of the virus – three haemagglutinating (Vt97, Triptis, Hartmannsdorf) and two non-haemagglutinating (Pv97, 9905 RHDVa). The specific immunological response was measured by the dynamics of changes in the amount of lymphocytes T (with CD5+, CD4+, CD8+, CD25+ receptor) and B (with CD19+ receptor). The study showed differences in immunogenicity of the analysed RHDV antigenic variants, which allowed them to be divided into groups of: more immunogenic strains, including non-haemagglutinating 9905 RHDVa and haemagglutinating Vt97 and Triptis variants; and less immunogenic strains, including the haemagglutinating Hartmannsdorf variant and the non-haemagglutinating Pv97 variant. Such a result may indicate that the agglutination capacity of red blood cells might not be a factor impacting the number of T and B lymphocytes.

    Opis:
    The present paper refers to the cytometric analysis of lymphocytes T (with receptor CD5+), Th (with receptor CD4+), Tc/Ts (with receptor CD8+), lymphocytes CD25+ and lymphocytes B with receptor CD19+ in rabbits experimentally infected with strains of RHD virus - Rainham, Frankfurt and Asturias, not having haemagglutinogenic capacities, which makes them unique, as haemagglutinogenic capacity is a classic and typical property of most strains of this virus. The study was performed in the dynamic system, drawing blood samples from animals at hour 0, namely before the administration of the viral antigen, and then at 4, 8, 12, 24 and 36 h after the infection. The study indicated that Rainham and Asturias strains of RHD virus cause a similar amount of changes as the most immunogenic haemagglutinogenic strains CAMP V-561 and CAMP V-562 of the RHD virus do. In contrast, the Frankfurt strain of the RHD virus is characterised with 5-6-fold lower reactivity in this respect and is most similar to the least immunogenic haemagglutinogenic strain CAMP V-558 of the RHD virus.

    Opis:
    The present study was aimed at determining changes in chosen elements of phagocytosis in rabbits infected with 3 antigenic variants of RHD – Hartmannsdorf, Pv97 and 9905, which differed in haemagglutination ability. The animals were tested for phagocytosis parameters, and the results revealed that the examined strains showed the differences. These variations regarded mainly Pv97 strain, as the intensity of the changes were 5 times stronger in comparison to strain Hartmannsdorf and 9905. As all of the strains examined are signified as antigenic variants, we have stated that this feature does not determine their immunological picture. The results suggest the existence of immunological dissimilarities among strains of the RHD virus, which was revealed for the first time in antigenic variants.

    Opis:
    The paper describes the immunological response in the matter of percentage of T cells (receptor CD5+) and subpopulations (Th with receptor CD4+, Tc/Ts with receptor CD8+, T with receptor CD25+) and B cells with receptor CD19+, as well as the percentage of apoptotic granulocytes and lymphocytes, in rabbits experimentally infected with the Hagenow strain of the RHD virus. The material chosen for the experiment is special, as among all strains of RHD virus, there are only two strains which carry the variable haemagglutination capacity of red cells. The results of the study show that the Hagenow strain gives an untypical picture of T and B lymphocytes, whereas the results in inducing apoptosis seems to corespond with previous data, confirming the inclusion of apoptosis from 4 h p.i. and the intensity of the phenomenon being higher in granulocytes.

    Opis:
    This paper presents the way of identifying the influence of the tolerance of model pumps (TYPE 3PWR-SE) construction on the total efficiency. The identification of sensitive control dimensions (Value / Tolerance) of examined pumps has been made by means of the multi-valued logic and inductive decision trees. In order to confirm the obtained results, multiple-valued logic trees have been used in the paper according to algorithms for the minimization of individual logic functions. What is more, a specific monotonicity of values of the most key parameters has been determined for the investigated set of pumps having individual specification numbers.

    Opis:
    The paper concerns the use of a novel, very effective diagnostic method, a real-time PCR for diagnosis of a viral agent causing viral haemorrhagic disease in rabbits – RHDV. Until now, the method was widely used for detecting many different viruses, both DNA, and RNA, but as far as RHDV is concerned, there are not many records of such use. This study aimed at the detection of 17 different strains from different European regions, differing in biological features and mortality. The study confirmed that real-time PCR is an applicable and effective method for diagnosis of RHDV, irrespective of the stains’ features.

    Opis:
    The objective of the study was to determine values of apoptosis for peripheral blood lymphocytes and granulocytes, including dependency on the season of the year, in Polish mixed-breed rabbits and in mixed-breed rabbits with the addition of blood of meat-breed rabbits. The study was carried out in four seasons of the year (spring, summer, autumn, winter) involving 120 Polish mixed-breed rabbits – group I, and 120 Polish mixed-breed rabbits with addition of meat-breed rabbit blood – group II. Assessment of apoptosis of lymphocytes and granulocytes was performed using as FACScan cytometer by Becton Dickinson with FACSDiva software (USA), using as ApoFluor®Green Caspase reagent kit (MP Biomedicals, USA) to detect the activity of the total caspase pool 1, 3, 4, 5, 6, 7, 8, 9 in granulocytes and lymphocytes of rabbit peripheral blood. The results for apoptosis of lymphocytes and granulocytes in peripheral blood in the animals investigated (group I and II) were subjected to statistical analysis with the t’Student test at p=0.05. It was noted that, in rabbits from group I, the values for apoptosis of lymphocytes were the highest in winter and autumn (36.02% and 31.24%, respectively), and the lowest in spring and summer (26.73% and 22.72%, respectively), whereas in the case of granulocytes the highest values were in summer and spring (14.69% and 12.95%, respectively), and the lowest in winter and autumn (8.16% and 8.57%, respectively). In mixed-breed rabbits with the addition of meat-breed blood (group II), the values for apoptosis of lympocytes were the highest in spring (29.13%), and the lowest in summer (25.43%); whereas in the case of granulocytes the highest values were in summer and spring (14.0% and 11.15%, respectively), and the lowest in autumn and winter (7.46% and 7.64%, respectively).

    In the paper we studied haematologic values,such as haemoglobin concentration, haematocrit value, thrombocytes, leucocytes: lymphocytes, neutrophils, basophils, eosinophils and monocytes in the pheral blood in Polish mixed-breeds with addition of meat breed blood in order to obtain the reference values which are until now not available for this animals. In studying this indices we took into consideration the impact of the season (spring, summer, autumn, winter), and sex of the animals. The studies have shown a high impact of the season of the year on those rabbits, but only in spring and summer. Moreover we observed that the sex has mean impact on the studied values of haematological parameters in those rabbits. According to our knowledge, this is the first paper on haematologic values in this widely used group of rabbits, so they may serve as reference values.

    Opis:
    In Poland, rabbit is a highly valued animal, due to dietetic and flavour values of its meat, but above all, rabbits tend to be commonly used laboratory animals. The aim of the study was developing standards for counts of B-cells with CD19+ receptor, T-cells with CD5+ receptor, and their subpopulations, namely T-cells with CD4+, CD8+ and CD25+ receptor in the peripheral blood of mixed-breed Polish rabbits with addition of blood of meet breeds, including the assessment of the impact of four seasons of the year and animal sex on the values of the immunological parameters determined. The results showed that the counts of B- and T-cells and their subpopulations in peripheral blood remain within the following ranges: for CD19+ B-cells: 1.05 - 3.05%, for CD5+ T-cells: 34.00 - 43.07%, CD4+ T-cells: 23.52 - 33.23%, CD8+ T-cells: 12.55 - 17.30%, whereas for CD25+ T-cells: 0.72 - 2.81%. As it comes to the season of the year, it was observed that it principally affects the values of CD25+ T-cells, while in the case of rabbit sex, more changes were found in females.

    Opis:
    Mixed-breed rabbits in Poland are widely used for diagnostic and scientific research and as utility animals, therefore there is a need to know their immunological status, as well as their haematological status. In this study natural immunity factors were analyzed in Polish mixed-breed rabbits and Polish mixed-breed rabbits with addition of blood of meet-breed, considering the impact of sex and season of the year (spring, summer, autumn, winter) using measurement of non-specific cellular and humoral immunity parameters in peripheral blood. The study has revealed that there is a variety between the two commonly used mixed-breed types of rabbits, especially when sex and season is concerned, which is crucial for using these animals in experiments.

    The aim of the study was to develop reference values for such haematologic values as haemoglobin concentration, haematocrit value, volume of erythrocytes, thrombocytes, leucocytes, lymphocytes, neutrophils, basophils, eosinophils and monocytes in peripheral blood in Polish mixed-breed rabbits, considering the impact of the season (spring, summer, autumn, winter), and sex of the animals. The results reveal, that the season of the year has a small impact in Polish mixed-breed rabbits, and it principally referred to spring and summer. Finally it was shown, that sex has average impact on the studied values of haematological parameters.

    Opis:
    The paper presents the possible applications of using acoustic diagnostics in inspecting the technical condition of an internal combustion engine with autoignition on the example of the Fiat drive unit with common rail system. As a result of measuring the sound pressure level for specific faults and comparing the noise generated by the motor running smoothly, the detailed maps of changes in the acoustic spectrum are possible to generate. These results may be helpful in the future diagnostics of internal combustion engines. In the paper, the results of scientific work in the area of research, design and operation of internal combustion engines, conducted at the Department of Automotive Engineering, in cooperation with the Laboratory of Hydraulic Drives & Vibroacoustics of Machines at the Wroclaw University of Technology are included.
