    The effect of ketotifen on inflammation in the intestine during T. spiralis infection in BALB/c mice was examined. The lack of enteropathy in treated mice was accompanied to affected the size of worms and the number of worms, but did not prevent the retardation of nematodes in the intestine. Fecundity of females in vitro and the number of muscle larvae were not statistically changed after treatment. Ketotifen reduced the number of mast cells and IgA plasma cells in the intestine. As inflammatory influx, epithelial damage and IgA response are related to the action of T cells, ketotifen affected T dependent reactions in the gut of T. spiralis infected mice.

    Opis:
    The aim of this paper is to study periodic solutions of Marchuk's model, i.e. the system of ordinary differential equations with time delay describing the immune reactions. The Hopf bifurcation theorem is used to show the existence of a periodic solution for some values of the delay. Periodic dynamics caused by periodic immune reactivity or periodic initial data functions are compared. Autocorrelation functions are used to check the periodicity or quasiperiodicity of behaviour.

    Opis:
    Patients with plasma cell disorder require a medical examination that will enable in a quick way to make a diagnosis, treatment selection and conduct patient monitoring during drug therapy. The aim of this study was to determine the concentration of serum immunoglobulin and light free chains in patients with monoclonal gammopathy. The blood serum of patients was evaluated in the Beskid Hematological Clinic Cancer Center – City Hospital in Bielsko-Biała. The serum of immunoglobulin light free chains was determined by using commercially available tests by the Binding Site company. Assay validation was performed in the serum light free chains of immunoglobulin by setting the analytical range of the method, linearity, precision, analytical sensitivity, recurrence and limit of detection as well as quantification methods. The results obtained indicate that the determination of serum immunoglobulin and light free chains is important in the diagnosis of patients with multiple myeloma and other monoclonal gammopathy, such as smouldering myeloma, light chain disease, gammopathy of undetermined significance, non-Hodgkin lymphoma and amyloidosis.

    Opis:
    The primary physical and chemical parameters that define the hypopolarized plasma cell membrane of malignant (cancer) cells compared to non-malignant cells reflect universal characteristics. The median value for the resting membrane potential is the constant for the Nernst equation without reference to discrepancies in ion concentrations and is identical to Boltzmann energies at 37 °C. The threshold energy defining space-time converges with access to entropic processes that are reflected in the morphology of cancer cells and tumors. Slowing of growth in cancer cell lines but not normal cells following exposure to weak (~1 to 10 μT) patterned magnetic fields occurs when the energy induced within the cell corresponds to the energy equivalent of the hypopolarized membrane potential. The optimal temporal parameters for the efficacy of these fields can be derived from Hubble‟s parameter and the transform function for “noise” or “random” patterns within the system. Quantitative solutions and experimental data indicate that the cancer cell may be dominated by entropic process that can be attenuated or blocked by temporally-structured applied magnetic fields whose intensity matches the increment of energy associated with this threshold.

    Opis:
    Introduction: Inflammatory myofibroblastic tumor (IMT) is a rare condition that can mimic potentially more dangerous states such as malignant tumors. The tumor itself can also show local malignancy as well as malignant transformation. The paranasal sinus IMT is quite a rare case in the literature. The manifestation of the disease can include face swelling, nasal obstruction, epistaxis, vision acuity worsening, numbness of the face, pain. Etiology of this type of lesion still remains uncertain but there are a few assumptions on the issue: viral and genetic, as well as posttraumatic and postinflammatory. We report a case of an adult woman with IMT detected in the right maxillary sinus after endoscopic sinus surgery. Case report: We report the case of an adult woman with IMT detected in right maxillary sinus after endoscopic sinus surgery.
    Wstęp: Zapalny guz miofibroblastyczny (IMT) jest rzadkim stanem, który może naśladować potencjalnie bardziej niebezpieczne choroby, takie jak nowotwory złośliwe. Sam guz może również wykazywać miejscową złośliwość, a także złośliwą transformację. IMT zatok przynosowych jest dość rzadko opisywany w literaturze. Objawem choroby może być obrzęk twarzy, niedrożność nosa, krwawienie z nosa, pogorszenie ostrości wzroku, drętwienie twarzy, ból. Etiologia tego typu zmian nadal pozostaje niejasna, ale rozważa się następujące przyczyny powstawania guza: wirusową, genetyczną, a także pourazową i pozapalną. Niniejszy opis przypadku dotyczy dorosłej kobiety z IMT wykrytym w prawej zatoce szczękowej po endoskopowej operacji zatok. Opis przypadku: Niniejszy opis przypadku dotyczy dorosłej kobiety z IMT wykrytym w prawej zatoce szczękowej po endoskopowej operacji zatok.

    Opis:
    There is a growing trend in the engineering of biomaterials, focusing on surface modifications of biomaterials to improve their mechanical strength, corrosion resistance, and biological properties. Cold plasma treatment may improve biological properties of biomaterials for biomedical applications by enhancing their integration with host tissue. This study investigated the influence of different cold plasma treatments on the surface properties of a polysaccharides- -based biomaterial to improve cell adhesion to its surface. The samples were subjected to plasma treatment using three different reactors operating at atmospheric pressure: gliding arc discharge (GAD) reactor, dielectric barrier discharge (DBD) plasma jet, and DBD surface reactor. Next, surface chemistry of the biomaterial after plasma treatment was determined by ATR-FTIR analysis. Furthermore, a cell adhesion assay on the samples was carried out using normal human skin fibroblasts (BJ cell line). The attenuated total reflection Fourier transform infrared analysis (ATR- -FTIR) showed that new potential functional groups could be formed on the material surface after plasma treatment. However, plasma treatment of the samples did not enhance cell adhesion to the surface of the polysaccharides-based biomaterial. Thus, the obtained results indicate that plasma treatment using GAD reactor, DBD plasma jet, and DBD surface reactor was not effective for surface modification and cell responses.

    Opis:
    The metabolism of oxygen in aerobic organisms leads to generation of reactive oxygen species (ROS). These entities are able to oxidize almost all classes of macromolecules, including proteins, lipids and nucleic acids. The physiological level of ROS is usually regulated by antioxidant defense mechanisms. There are at least three groups of antioxidant enzymes: superoxide dismutases, catalases and glutathione peroxidases (GSH-Pxs) which neutralize ROS. The trace elements (copper, zinc and selenium) bound to the active sites of the above listed enzymes play an important role in the antioxidant defense system. In mammals, a major function of selenium (Se) and Se-dependent GSH-Pxs is to protect cells from oxidative stress. Selenium concentrations and GSH-Px activities are altered in blood components of chronic kidney disease (CKD) patients. The Se level is frequently lower than in healthy subjects and the concentration very often decreases gradually with advancing stage of the disease. Studies on red cell GSH-Px activity in CKD patients reported its values significantly lower, significantly higher and lower or higher, but not significantly as compared with healthy subjects. On the other hand, all authors who studied plasma GSH-Px activity have shown significantly lower values than in healthy subjects. The degree of the reduction decreases gradually with the progression of the disease. High inverse correlations were seen between plasma GSH-Px activity and creatinine level. A gradual decrease in plasma GSH-Px activity in CKD patients is due to the fact that this enzyme is synthesized predominantly in the kidney and thus the impairment of this organ is the cause of the enzyme's lower activity. Se supplementation to CKD patients has a slightly positive effect in the incipient stage of the disease, but usually no effect was observed in end-stage CKD. Presently, kidney transplantation is the only treatment that may restore plasma Se level and GSH-Px activity in patients suffering from end-stage CKD. A few studies have shown that in kidney recipients, plasma Se concentration and GSH-Px activity are restored to normal values within a period of 2 weeks to 3 months following surgery and thus it can be acknowledged that Se supplementation to those patients has a positive effect on plasma GSH-Px activity.

    Opis:
    Objectives: The method for the determination of As, Al, Cd, Ni, Pb (toxic elements) and Cr, Co, Cu, Fe, Mn, Zn (essential elements) in human urine by the use of Inductively Coupled Plasma Mass Spectrometry (quadrupole ICP-MS DRCe Elan, Perkin Elmer) with the dynamic reaction cell (DRC) was developed. Materials and Methods: The method has been applied for multi-element analysis of the urine of 16 non-exposed healthy volunteers and 27 workers employed in a copper smelter. The analysis was conducted after initial 10-fold dilution of the urine samples with 0,1% nitric acid. Rhodium was used as an internal standard. The method validation parameters such as detection limit, sensitivity, precision were described for all elements. Accuracy of the method was checked by the regular use of certified reference materials ClinCheck®-Control Urine (Recipe) as well as by participation of the laboratory in the German External Quality Assessment Scheme (G-EQUAS). Results: The detection limits (DL 3s) of the applied method were 0.025, 0.007, 0.002, 0.004, 0.004, 0.086, 0.037, 0.009, 0.016, 0.008, 0.064 (μg/l) for Al, As, Cd, Cr, Co, Cu, Fe, Mn, Ni, Pb, Zn in urine, respectively. For each element linearity with correlation coefficient of at least 0.999 was determined. Spectral interferences from some of the ions were removed using DRC-e with addition of alternative gas: methane for cobalt, copper, cadmium, chromium, iron, manganese, nickel and rhodium, and oxygen for arsenic. Conclusions: The developed method allows to determine simultaneously eleven elements in the urine with low detection limits, high sensitivity and good accuracy. Moreover, the method is appropriate for the assessment of both environmental and occupational exposure.

    Opis:
    Nowadays, various microfluidic platforms are developed with a focus on point-of-care diagnostics in the biomedical field. Segregation of blood cells and plasma remains an essential part of medical diagnosis in which isolation of platelets (PLTs), red blood cells (RBCs), and white blood cells (WBCs) is a requirement for analysis of diseases associated with thrombocytopenia, anemia, and leukopenia. However, a separated plasma contains proteins, nucleic acids, and viruses, for which a microfluidic device is introduced for continuous separation of PLTs, RBCs, and WBCs with a diameter range of 1.8–2 m, 5–6 m, and 9.4–14 m, respectively, and plasma using the negative dielectrophoresis (DEP) force principle. In this study, design of the device is explored utilizing COMSOL Multiphysics 5.4 tool. This design consists of triangular micro-tip electrodes at the top, which are effective in generating a nonuniform electrical field with a significantly small AC voltage. Furthermore, the blood cells are subjected to the negative DEP force resulting in deflection toward their respective outlets, due to which blood cell separation purity and efficiency from the sample, i.e., of PLTs, RBCs, and WBCs, improve and are obtained at a blood sample flow velocity of 700 m/s and buffer solution flow velocity of 1200 m/s with 12 Vpp electrode voltage, after experimenting and testing at multiple flow velocities. Additionally, a curved microchannel is introduced, producing better plasma flow velocity than a flat microchannel at the side outlets (top and bottom). The cell-free diluted plasma is collected at side outlets (top and bottom) with high purity and improved separation efficiency.

    Opis:
    To investigate the dynamics of a planar plasma diode system (PDS), a model based on the current density equilibrium at the interface was developed. The current densities and plasma boundary variations with the potential fields were obtained by simulating a single square pulse. The variation of an observed overshoot current density with the applied voltage is presented. Planar plasma diode system was also simulated for periodic, sine, square, triangular and saw tooth voltage patterns by varying the amplitude and frequencies. A method to find the lower bound of the electron density of plasma for a specified PDS is presented. Particle-In-Cell simulation technique was used to investigate the plasma particles and electric field distributions over the anode cathode gap for different intensities of external electric fields. The system became stable after few time steps and this time depends upon the intensity and polarization of the external field.

    Opis:
    Existing global models of interaction between the solar wind (SW) and the local interstellar medium (LISM) describe the heliosphere that arises as a result of this interaction. There is a strong motivation to develop a kinetic model using the Particle-in-Cell (PIC) method to describe phenomena which appear in the heliosphere. This is however a long term scientific goal. This paper describes an electrostatic Particle-in-Cell numerical model developed in the Institute of Aviation in Warsaw, winch includes mechanical and charge exchange collisions between particles in the probabilistic manner using Direct Simulation Monte Carlo method. This is the first step into developing simulations of the heliosphere incorporating kinetic effects in collisionless plasmas. In this paper we focus only on presenting the work, which have been done on the numerical PIC algorithm.
    Istniejące globalne modele oddziaływania wiatru słonecznego (SW) z lokalną materią międzygwiazdową (LISM) opisują heliosferę, która powstaje w wyniku interakcji tych dwóch ośrodków. Istnieje silna motywacja do opracowania modelu kinetycznego wykorzystującego metodę Particle-in-Cell (PIC) w celu opisu zjawisk, które zachodzą w heliosferze. Jednakże jest to długoterrninowy cel naukowy. W artykule przedstawiono elektrostatyczny model numeryczny PIC. opracowany w Instytucie Lotnictwa w Warszawie, który obejmuj e kolizje mechaniczne i rezonansową wymianę ładunków pomiędzy cząstkami w sposób probabilistyczny metodą Direct Simulation Monte Carlo. Jest to pierwszy krok w opracowywaniu symulacji heliosfery zawierającej efekty kinetyczne w plazmach bezzderzeniowych. W tym artykule koncentrujemy się tylko na prezentowaniu prac, które zostały wykonane z wykorzystaniem algorytmu numerycznego PIC.

    Opis:
    Low density polyethylene (LDPE) was modified by an Ar plasma discharge and then grafted with glycine (Gly), bovine serum albumin (BSA) or polyethylene glykol (PEG). Some plasma-treated samples and samples grafted with BSA were exposed to a suspension of colloidal carbon particles (C, BSA+C). Pristine LDPE and tissue culture polystyrene dishes (PSC) were used as control samples. The materials were seeded with rat aortic smooth muscle cells and incubated in a medium DMEM with 10% of fetal bovine serum. On day 1 after seeding, the cells on LDPE modified with plasma only, Gly, BSA and BSA+C adhered in similar numbers as on PSC, while the values on non-modified and PEG-modified samples were significantly lower. On day 5, the highest cell numbers were found again on LDPE with Gly, BSA and BSA+C. On day 7, the highest number of cells was found on LDPE modified only with plasma. The latter cells also dis-played the largest cell spreading area. The increased cell colonization was probably due to the formation of oxygen-containing chemical functional groups after plasma irradiation, and also due to positive effects of grafted Gly, BSA and BSA in combination with colloidal C particles.

    Opis:
    The attractiveness of synthetic polymers for cell colonization can be affected by physical and chemical modification of the polymer surface. In this study, high density polyethylene (HDPE, m.w. 0.952g/cm3) and low density polyethylene (LDPE, m.w. 0.922g/cm3) were modified by an Ar plasma discharge using Balzers SCD 050 device (exposure time 10, 50, 150 and 400 seconds, discharge power 1.7W). The material was then seeded with rat aortic smooth muscle cells (RASMC; passages 8 to 9, 17 000 cells/cm3) and incubated in a DMEM medium with 10% of fetal calf serum. On day 1 after seeding, the number of initially adhered cells was significantly higher on all modified HDPE and LDPE samples. On day 2, this difference persisted in HDPE, whereas in LDPE only the values on the samples modified by 150 and 400 seconds were significantly higher. On the 5th and 7th day, there were no significant differences in cell number among all LDPE samples. However, on the HDPE foils, significant differences were still apparent on the samples modified for 400 seconds. The cell spreading areas measured on day 1 after seeding were significantly larger on all modified LDPE samples, and, on day 2, on the HDPE samples exposed for 150s. The increased cell colonization was probably due to the formation of oxygen-containing chemical functional groups in the polymer. These results suggest that the responsiveness of the cell to the changes in physiochemical surface properties was more pronounced in HDPE than in LDPE. On both types of polyethylene, the most appropriate exposure time for the enhancement of cell adhesion and growth seemed to be 150 and 400 seconds.

    Opis:
    The effects of inhibitors of plasma membrane NADPH oxidase on menadione-induced cell injury processes were studied using human osteosarcoma 143B cells. The intracellular level of superoxide in the cells treated with menadione for 6 h reached a maximum followed by an abrupt decrease. The population of apoptotic cells detected by Annexin V and propidium iodide double staining also reached its maximum at 6 h of menadione-treatment while that of necrotic cells increased continuously reaching 90% of the total population at 9 h of the treatment. Pretreatment of the cells with inhibitors of NADPH oxidase, including diphenyliodonium chloride, apocynin, N-vanillylnonanamide and staurosporine was effective in lowering the menadione-induced elevations of superoxide, and also in the suppression of the switch of the cell death mode from apoptosis to necrosis in menadione-treated cells except for the case of staurosporine. These results strongly suggest that superoxide generated by NADPH oxidase, besides that generated by the mitochondria, may contribute to the remarkable increase in the intracellular level of superoxide in the cells treated with menadione for 6 h resulting in the switch from apoptosis to necrosis, although a direct evidence of the presence of active and inactive forms of NADPH oxidase in control and menadione-treated 143B cells is lacking at present.

    Opis:
    This contribution presents results of a Particle-in-Cell simulation of ion beam acceleration via the interaction of a petawatt 25 fs laser pulse of high intensity (up to ~1021 W/cm2) with thin hydrocarbon (CH) and erbium hydride (ErH3) targets of equal areal mass density (of 0.6 g/m2). A special attention is paid to the effect that the laser pulse polarization and the material composition of the target have on the maximum ion energies and the number of high energy (>10 MeV) protons. It is shown that both the mean and the maximum ion energies are higher for the linear polarization than for the circular one. A comparison of the maximum proton energies and the total number of protons generated from the CH and ErH3 targets using a linearly polarized beam is presented. For the ErH3 targets the maximum proton energies are higher and they reach 50 MeV for the laser pulse intensity of 1021 W/cm2. The number of protons with energies higher than 10 MeV is an order of magnitude higher for the ErH3 targets than that for the CH targets.

    Ukosowanie blach tradycyjnie jest wykonywane ręcznie, za pomocą tzw. sekatorów. Tak realizowany proces jest pracochłonny, a jego efekt często nie jest zadowalający pod względem jakości. Proces ukosowania ręcznego stwarza ponadto bardzo niebezpieczne warunki pracy. Te mankamenty nie występują w zrobotyzowanych stanowiskach ukosowania. W artykule przedstawiono techniczne, organizacyjne i ekonomiczne aspekty robotyzacji ukosowania blach z zastosowaniem technologii cięcia plazmowego. Wykorzystano doświadczenia z wdrożenia w TAGOR S.A. zrobotyzowanego stanowiska ukosowania opracowanego przez zespół aplikacyjny PIAP przy udziale specjalistów z TAGOR. Opisane stanowisko jest eksploatowane w zakładzie od blisko dwóch lat.
    Traditionally, metal sheets bevelling has been performed manually. It is a very laborious process, whose effects are often not satisfactory in terms of quality. Moreover, manual bevelling is performed in highly hazardous work environment. Robotized cells eliminate all such disadvantages. The economic, organizational and technical aspects of the robotised metal sheets bevelling with of plasma cutting are presented in the paper. Authors have utilised the experiences from preparation and application of robotized cell for metal sheets bevelling by plasma cutting. It was first developed through the joint effort of PIAP's design & implementation team with the help of specialists from TAGOR S.A. In this factory the cell was installed and is exploited since two years.

    Opis:
    Cell wall proteins of Candida albicans, besides their best known role in the adhesion of this fungal pathogen to host's tissues, also bind some soluble proteins, present in body fluids and involved in maintaining the biochemical homeostasis of the human organism. In particular, three plasma factors - high-molecular-mass kininogen (HK), factor XII (FXII) and prekallikrein (PPK) - have been shown to adhere to candidal cells. These proteins are involved in the surface-contact-catalyzed production of bradykinin-related peptides (kinins) that contribute to inflammatory states associated with microbial infections. We recently identified several proteins, associated with the candidal cell walls, and probably involved in the binding of HK. In our present study, a list of potential FXII- and PPK-binding proteins was proposed, using an affinity selection (on agarose-coupled FXII or PPK) from a whole mixture of β-1,3-glucanase-extrated cell wall-associated proteins and the mass-spectrometry protein identification. Five of these fungal proteins, including agglutinin-like sequence protein 3 (Als3), triosephosphate isomerase 1 (Tpi1), enolase 1 (Eno1), phosphoglycerate mutase 1 (Gpm1) and glucose-6-phosphate isomerase 1 (Gpi1), were purified and characterized in terms of affinities to the human contact factors, using the surface plasmon resonance measurements. Except Gpm1 that bound only PPK, and Als3 that exhibited an affinity to HK and FXII, the other isolated proteins interacted with all three contact factors. The determined dissociation constants for the identified protein complexes were of 10-7 M order, and the association rate constants were in a range of 104-105 M-1s-1. The identified fungal pathogen-host protein interactions are potential targets for novel anticandidal therapeutic approaches.

    Opis:
    Fast electrons created as a result of the laser beam interaction with a solid target penetrate into the target material and initialize processes leading to the generation of the characteristic X-ray K-α radiation. Due to the strong electric field induced at the rear side of a thin target the transmitted electrons are redirected back into the target. These refl uxing electrons increase the K-α radiation yield, as well as the duration of the X-ray pulse and the size of the radiation emitting area. A model describing the electron refl uxing was verifi ed via particle- -in-cell simulations for non-relativistic electron energies. Using this model it was confi rmed that the effect of the electron refluxing on the generated X-ray radiation depends on the target thickness and the target material. A considarable increase of the number of the emitted K-α photons is observed especially for thin targets made of low-Z materials, and for higher hot electron temperatures.

    Opis:
    Three monoclonal antibodies specific to the central cell-binding and the C- and N-terminal domains of fibronectin (FN) were used to test antigenic epitope accessibility on human plasma and cerebrospinal fibronectins. In the plasma group, the mean N-terminal FN domain immunoreactivity was about one fourth that of the cell-binding and C-terminal domains, whereas in cerebrospinal fluid they were nearly equal. In the presence of 0.5-6 M urea N-terminal domain immunoreactivity in the plasma increased 3-6-fold, but it decreased 0.7-3-fold in the cerebrospinal fluid. Analysis of fibronectin domain immunoreactivities of the cell-binding and N-terminal domains by a panel of specific monoclonal antibodies may reveal N-terminal fibronectin domain accessibility for reaction with biological partner ligand(s) and/or processes in which FN could be implicated. Such determinations may have important clinical implications.
