    Wstęp. W ostatnim okresie czasu zdecydowanie wrasta zainteresowanie jakością życia w aspekcie zdrowia. Takie spojrzenie na zdrowie może wynikać z uznania i zaakceptowania holistycznego spojrzenia na człowieka. Badania dotyczące wpływu zdrowia jamy ustnej na jakość życia pacjentów są prowadzone stosunkowo rzadko. Współcześnie do tych badań można wykorzystywać wskaźniki zarówno ogólne, jak i specyficzne. Celem badań było określenie jakości życia chorych na choroby przyzębia na podstawie badania ankietowego kwestionariuszem GOHAI (Geriatric Oral Health Assessment Index). Materiał i metodyka. Badania przeprowadzono w okresie od 3 listopada do 15 grudnia 2013 r. w przyzakładowej przychodni stomatologicznej Państwowej Wytwórni Papierów Wartościowych w Warszawie. W badanej grupie było 32 osoby (11 kobiet i 21 mężczyzn) w wieku 27-67 lat. Każdego badanego objęto dwuetapowym badaniem: I etap Najpierw lekarz dentysta przystąpił do badania klinicznego, w którym oceniono występowanie potrzeb leczniczych u pacjentów oraz stan zdrowia jamy ustnej. Każdy pacjent został zbadany przy sztucznym oświetleniu, przy użyciu lusterka i zgłębnika. Na tym etapie wyselekcjonowano grupę chorych z chorobami przyzębia. Ta grupa była przedmiotem dalszych badań w II etapie- badań ankietowych. II etap Badanie ankietowe kwestionariuszem GOHAI (Geriatric Oral Health Assessment Index. Wyniki badań i wnioski. 1.Rozkład odpowiedzi (punktacji) na poszczególne pytania kwestionariusza GOHAI był mocno zróżnicowany. Wśród badanych rozkład punktacji wahał się w przedziale 19-46. Średnia ilość punków jaką uzyskali chorzy na choroby przyzębia wynosiła 30. 2. Większość dolegliwości wynikające z rozwoju chorób przyzębia występowały z różną częstością wahającą się od jednej trzeciej do około połowy liczby ankietowanych. 3. Dla dokonania bardziej pogłębionej analiz konieczne jest powtórzenie tego typu badań na zdecydowanie większej grupie chorych z chorobami przyzębia.Introduction. The interest in the quality of life as far as health is concerned has recently noticeably increased. Such an attitude towards health may result from the acceptance of a holistic approach to a person. Studies on the influence of the health of oral cavity on the patient's quality of life are relatively infrequent. Nowadays, such studies can utilise general as well as specific indices. The aim of this study was to determine the quality of life of persons suffering from periodontal diseases basing on the GOHAI (Geriatric Oral Health Assessment Index) questionnaire. Materials and Methods. The study was carried out between 3 November and 15 December 2014 in the company dental clinic of the Polish Security Printing Works in Warsaw. The studied group consisted of 32 persons (11 women and 21) men aged 27-67. Each of the studied people underwent a two-stage process: Stage I At first, a dentist carried out a clinical examination assessing the patient's needs for treatment and the health of oral cavity. Each of the patients was examined in artificial lighting, with a mirror and a dental probe. In this stage, a group of persons with periodontal diseases was selected. The group was subject to further study in the stage II – the survey. Stage II Survey study with the use of the GOHAI (Geriatric Oral Health Assessment Index) questionnaire. Results and Conclusions. 1.The distribution of answers (score) for given questions of the GOHAI questionnaire was strongly diversified. Among the studied persons, the score distribution ranged from 19 to 46. The average score obtained by the persons suffering from periodontal diseases was 30. 2.Most of the conditions resulting from the development of periodontal diseases occurred with various frequency in 1/3 to ca. 1/2 of the respondents. 3. For a more in-depth analysis, the repetition of this type of study on a considerably greater number of persons suffering from periodontal diseases will be required

    Early postnatal development of the lumbar vertebrae in male Wistar rats: double staining and digital radiological studies

    The aim of the study was to evaluate the physiological developmental changes of male rats’ lumbar vertebrae during the first 22 days after birth. Morphology and mineralisation of lumbar vertebrae were evaluated using double-staining and digital radiography system, which allowed vertebral width and optical density to be determined. Pup weight, crown-rump length, body mass index and vertebral width increased during postnatal period and significantly correlated with their age. Bone mineralisation, as measured by optical density, did not show any significant differences. The complete fusion of the primary ossification centres had a cranio- -caudal direction and started on day 19 after parturition but was incomplete by day 22. It could be concluded that, unlike significant age-related increase of vertebral size, mineralisation was only slightly elevated during evaluated postnatal period. The method described is supplementary to alizarin red S staining as it provides both qualitative and quantitative data on mineralisation in a similar manner to micro computed tomography but does not allow 3 dimensional and microarchitecture examination

    Despite the variety of modern molecular techniques available, examination of foetal anatomy is still a fundamental part of teratological studies in evaluating the developmental toxicity of xenobiotics or other non-chemical factors. The article presents contemporary methods of embryotoxicity and foetotoxicity assessment. A single alizarin red S and double alcian blue followed by alizarin red S staining, as well as various methods of soft tissue examination are discussed

    DATA OPTIMIZATION FOR 3D MODELING AND ANALYSIS OF A FORTRESS ARCHITECTURE

    Thanks to the recent worldwide spread of drones and to the development of structure from motion photogrammetric software, UAV photogrammetry is becoming a convenient and reliable way for the 3D documentation of built heritage. Hence, nowadays, UAV photogrammetric surveying is a common and quite standard tool for producing 3D models of relatively large areas. However, when such areas are large, then a significant part of the generated point cloud is often of minor interest. Given the necessity of efficiently dealing with storing, processing and analyzing the produced point cloud, some optimization step should be considered in order to reduce the amount of redundancy, in particular in the parts of the model that are of minor interest. Despite this can be done by means of a manual selection of such parts, an automatic selection is clearly much more viable way to speed up the final model generation. Motivated by the recent development of many semantic classification techniques, the aim of this work is investigating the use of point cloud optimization based on semantic recognition of different components in the photogrammetric 3D model. The Girifalco Fortress (Cortona, Italy) is used as case study for such investigation. The rationale of the proposed methodology is clearly that of preserving high point density in the model in the areas that describe the fortress, whereas point cloud density is dramatically reduced in vegetated and soil areas. Thanks to the implemented automatic procedure, in the considered case study, the size of the point cloud has been reduced by a factor five, approximately. It is worth to notice that such result has been obtained preserving the original point density on the fortress surfaces, hence ensuring the same capabilities of geometric analysis of the original photogrammetric model

    Biomechanical properties of bone depend on the composition and organization of collagen fibers. In this study, Raman microspectroscopy was employed to determine the content of mineral and organic constituents and orientation of collagen fibers in spongy bone in the human head of femur at the microstructural level. Changes in composition and structure of trabecula were illustrated using Raman spectral mapping. The polarized Raman spectra permit separate analysis of local variations in orientation and composition. The ratios of ν2PO43−/Amide III, ν4PO43−/Amide III and ν1CO32−/ν2PO43− are used to describe relative amounts of spongy bone components. The ν1PO43−/Amide I ratio is quite susceptible to orientation effect and brings information on collagen fibers orientation. The results presented illustrate the versatility of the Raman method in the study of bone tissue. The study permits better understanding of bone physiology and evaluation of the biomechanical properties of bone

    Columns packed with commercial glass beads 5 and 19 lm average size and a mixture of both (0.7 volume fraction of large particles) were used to analyse starch composition by hydrodynamic chromatography (HDC), applying water as mobile phase. To obviate retrogradation, experiments were carried out at column temperatures of 15 and 3 °C and several types of starch were assayed. In what concerns amylopectin and amylose separation, a better resolution and a lower pressure drop were obtained for the mixed binary packing when compared with the packing containing uniform 5 lm glass beads. A more efficient cooling of the mobile phase was also obtained with the mixed packing, which was determinant for improving resolution. For the Hylon VII starch the relative retention times (RRT) were 0.777 and 0.964 for amylopectin and amylose, respectively, while for the Tapioca starch the obtained RRTs were 0.799 and 0.923. Application of unbound glass beads as column packing not only might reduce equipment and running costs in preparative scale separations, but also proved to be useful as a fast and reliable method to monitor the amylose and amylopectin content of starch samples of different sources.FEDERThe authors wish to thank FCT for the grant provided to Dr. Alexander Yelshin (Yelshyn).
