    Opis:
    Celem pracy jest porównanie skuteczności różnych form i metod laseroterapii na podstawie przeglądu literatury. Uwzględniono opublikowane w latach 2003-2011 prace badawcze skatalogowane w medycznych bazach danych Pub-Med, Embase, Cochrane oraz liczne pozycje piśmiennictwa anglojęzycznego i polskiego z przedmiotowej tematyki. Dane wskazują na szerokie możliwości zastosowania laseroterapii, zarówno jako samodzielnej metody, jak również metody skojarzonej. Zauważalna jest jednak niewielka liczba badań naukowych o wysokiej jakości metodologicznej, a tylko właściwie zaplanowane i rzetelnie realizowane badania naukowe mają istotne znaczenie dla podejmowania ważnych decyzji terapeutycznych w praktyce klinicznej.
    The main goal of this paper is to compare the effectiveness of various forms and applied methods of laser therapy, basing on the literature survey. This review is based on the papers published in years 2003-2011, presented in the medical databases PubMed, Embase, Cochrane and in English and Polish language literature. The various laser therapy applications as an independent method or as a combination therapy, are discussed. There are some scientific studies of high methodological quality, what is important, since only carefully planned and thoroughly executed scientific studies are helpful in therapeutic decisions in clinical practice.

    Opis:
    Purpose: Subjects with post-stroke hemiparesis frequently present with asymmetric gait patterns. Symmetry, reflecting similarities in temporospatial, kinematic parameters, is an important measure of gait assessment. The study was designed to examine the relationships between asymmetry of temporal, spatial and kinematic gait parameters and walking velocity and distance. Methods: Temporospatial and kinematic gait parameters were examined in a group of 50 chronic post-stroke subjects and in a group of 25 healthy controls. Symmetry ratio was calculated for all the parameters. Gait velocity was measured during 10-metre test, the walking distance during 2-Minute Walk Test, and balance during Up&Go Test. Results: The relationship between stance phase duration symmetry and gait speed was at a moderate level (r = –0.43, p = 0.0173). There was a moderate relationship between swing phase symmetry and walking velocity and distance. The findings did not show a significant correlation between step length symmetry versus gait speed and distance. Conclusions: There is a mild relationship between self-selected gait velocity and walking distance versus temporal parameters symmetry. The findings do not confirm a relationship between self-selected gait velocity and walking distance versus spatial and kinematic parameters as well as balance. Likewise, no evidence confirms that asymmetry of temporal, spatial, kinematic gait parameters changes with the age of post-stroke subjects or is related to the length of time from stroke onset. Given the above, gait symmetry may be recognized as an important indicator of the level of gait control in post-stroke patients because it enables unique gait assessment, independent from other parameters.

    Opis:
    Purpose: The aim of the study is to define the impact of exercise on a treadmill on static balance and stability of posture in a group of patients after cerebral stroke rehabilitated in a late period, with an application of a treadmill with the function of visual biofeedback. Methods: The examination was carried out in a group of 46 people in a late period after ischemic cerebral stroke. The patients examined were randomly put to a group with intervention (n = 23), in which a rehabilitation programme with an application of a treadmill with the visual feedback function was realized and to a control group (n = 23). They evaluated balance in standing on both feet by means of a force plate, symmetry of load of lower limbs and dynamic balance in Up & Go test. Results: A statistically significant change of stabilometric parameters was observed only in the area of postural sways of the centre of pressure (COP). A significant improvement of the symmetry of load of lower limbs in standing ( p = 0.0266) was diagnosed in the examined group after the end of the programme. After the end of the programme no significant difference between the group with intervention and the control group as for a change of balance of the examined patients was found. Conclusions: In the examined group in the chronic period after cs no significant improvement of stabilometrically evaluated balance was obtained, but improvement of the symmetry of load of lower limbs as well as improvement of dynamic balance were observed.

    Opis:
    The Gait Variability Index (GVI) summarizes overall gait quality, taking into account spatiotemporal parameters from a 3-dimensional gait analysis. However, there are no studies evaluating changes in gait patterns after stroke, based on the GVI. The study was designed to assess usefulness of the GVI for evaluation of gait pathology in subjects with stroke, compared to healthy individuals. Methods: Spatiotemporal gait parameters were examined in a group of 50 subjects at a chronic stage post-stroke and in 50 healthy controls. The GVI was calculated based on the 9 spatiotemporal data. Results: The findings show statistically significant differences between the values of the GVI for paretic and non-paretic limbs ( p < 0.001). Higher values of the index were identified in the case of non-paretic limb: 80.74 vs. 76.32. The GVI scores were decreased for both paretic and non-paretic limbs, compared to the controls – p < 0.001. Conclusions: The GDI score seems to be a viable tool for quantifying changes in gait pattern during evaluation of subjects with chronic post-stroke hemiparesis. Further studies should be conducted to validate the use of GVI in the post-stroke population.

    Opis:
    Sex-ratio bias in seeds of dioecious Rumex species with sex chromosomes is an interesting and still unsettled issue. To resolve gender among seeds of R. acetosa and R. thyrsiflorus (two species with an XX/XY1Y2 sex chromosome system), this work applied a PCR-based method involving DNA markers located on Y chromosomes. Both species showed female-biased primary sex ratios, with female bias greater in R. acetosa than in R. thyrsiflorus. The observed predominance of female seeds is consistent with the view that the female biased sex ratios in Rumex are conditioned not only postzygotically but also prezygotically

    Opis:
    Powłoki tlenkowe wytworzone na podłożu aluminium o czystości technicznej impregnowano w procesie elektroforezy. Stosowano zawiesinę wodną cząstek teflonu. Ustalono wpływ wartości napięcia elektrycznego i czasu prowadzenia procesu elektroforezy na odporność na zużycie – w warunkach tarcia wytwarzanych impregnowanych powłok tlenkowych. Wykazano, że aluminium nieimpregnowane ma największą odporność na ścieranie. Proces impregnowania poprawia natomiast odporność korozyjną powłoki tlenkowej w roztworze HCl.
    Electrophoresis was employed in order to impregnate anodic coatings obtained onto aluminium. The water suspension composed of teflon particles was applied. The influence of voltage and time of electrophoresis on the abrasion resistance of the impregnated coatings was determined. It was shown that anodized aluminium is the most wear resistant coating. However, the impregnation process enhances the corrosion resistance of anodic coatings in the HCl solution.

    Opis:
    Al2Cu phase has been obtained by melting pure metals in the electric arc furnace. It has been found that the intermetallic phase undergoes selective corrosion in the H3PO4 aqueous solutions. Aluminium is dissolved, the surface becomes porous and enriched with copper. The corrosion rate equals to 371 ±17 g∙m-2∙day-1 (aerated solution) and 284 ± 9 g∙m-2∙day-1 (deaerated solution). The surface of Al2Cu phase after selective corrosion was characterised by using electrochemical impedance spectroscopy. It was found that the surface area of the specimens increases with temperature due to higher corrosion rate and is between 2137 and 3896 cm2.

    Opis:
    In the predominantly polyploid and apomictic genus Hieracium (Asteraceae) sexual diploids are extremely rare and their distribution is limited mainly to the refugial areas of southern Europe. Here we characterized for the first time the chromosome complex of the relict species Hieracium bracteolatum from a diploid population on the Greek Island of Evia. The cytogenetic analysis based on classical chromosome staining, C-banding/DAPI method and fluorescence in situ hybridization with rDNA probes (rDNA-FISH) showed no major differences in the karyotype structure between this relict species and other diploids within the genus, especially in terms of chromosome morphology and rDNA location. Our study is part of the still very scarce research on the karyotype organization in sexual Hieracium taxa.

    Opis:
    Horizontal gene transfer (HGT) is a process that allows genetic material to flow between even distantly related organisms. It is primarily observed in bacteria and protists but also in different lineages of eucaryotes. The first HGT cases in plants were discovered at the beginning of the 21st century and have been intensively studied ever since. Researchers have placed particular emphasis on the plant kingdom, especially parasitic plants. This review presents the current state of knowledge about this phenomenon in plants, with a special focus on parasitic plants. Among the described factors facilitating HGT, close physical contact between organisms is believed to be one of the most important. It is noted especially in the case of parasitism and similar relationships. For that reason, reported occurrences of this phenomenon in holoparasites, hemiparasites, and mycoheterotrophic plants are compared. The mechanisms responsible for HGT in plants still remain unclear, however, the studies described here suggest that both DNA and RNA may play a role as a carrier in that process. Also, the transfer between genomes of different organelles in the cell, intracellular gene transfer (IGT), and its relationships with HGT are described. The occurrence of the HGT and IGT phenomena concerning different genomes: nuclear, mitochondrial, and plastid is discussed in the review. Finally, some future areas of research in the field are proposed.

    Opis:
    The male-specific DNA markers are very useful in molecular sexing of non-flowering plants and seeds of dioecious species. In this paper we identified ten Y chromosome-specific RAPD primers suitable for identification of male plants in three Cannabaceae species with sex chromosomes (Humulus lupulus, XX/XY; H. japonicus, XX/ XY1Y2; Cannabis sativa, XX/XY). Basing on the nucleotide sequence of the OPJ-09 RAPD product we developed the HJY09 SCAR marker, which is very efficient in sexing of Japanese hop.
