Opis:
We present the case of a 70-year-old male patient with metastatic and castration-resistant prostate cancer as well as advanced bladder cancer, who suffered a non-ST-elevation myocardial infarction (NSTEMI). The cause of ischemia was critical left main stem stenosis, and right coronary artery stenosis. Initially, the patient was qualified for conservative treatment, but due to the intensifying symptoms of myocardial ischemia, it was decided that a hemodynamic intervention was necessary. Two drug-eluting stents were implanted, leading to clinical improvement. Following the treatment, the patient was considered as a candidate for further anti-cancer therapy. Unfortunately, due to the bladder cancer progression, anaemia and haemorrhage, his clinical condition exacerbated, and the patient died about 1 month from the cardiac intervention. Apart from the case description, the paper includes a review of literature on the treatment of acute coronary syndromes without ST-segment elevation in cancer patients.

The purpose of the study was to determine velocity changes in relation to the load lifted along with their muscular activity. Twenty athletes representing different sport disciplines, familiar with the flat bench press took part in the research project. The ANOVA analysis revealed a significantly higher effect on range of mean velocity (F = 128.34; η2 = 1.22 with p = 0.001) and maximal velocity (F = 7 3.31; η 2 = 0 .81 w ith p = 0 .001) t o m easured l oads ( 70÷100% 1-RM) i n a scending p hase. Tukey’s p ost-hoc t ests revealed a statistically significant difference between 70% and 100% 1-RM loads, in mean velocity with p = 0.001 and maximal velocity with p = 0.001. Similarly the results revealed a statistically significant difference between 80% and 100% 1-RM loads in mean velocity (p = 0,012) and maximal velocity (p = 0,021) during the ascending phase. Relationship between velocity and the muscles activity indicates that the anterior deltoid and latissimus dorsi muscles show synergy and a significant relationship for loads 90 and 100% 1-RM. The triceps brachii muscle shows a higher relationship with velocity of the barbell for loads 70% and 80%, then the relationship of the pectoralis major muscle with velocity only for 90% 1-RM.

Opis:
The aim of this study was to evaluate the effects of steroidal saponin supplementation on blood concentration of T, GH and IGF-1. The research involved 14 men between the age of 45 and 60 years. The duration of the experiment was 12 weeks. There were two series of laboratory tests. Independent tests were conducted at the beginning and after 12 weeks of the intervention. A two-way repeated measures ANOVA revealed a statistically significant effect of the intervention on the following variables: T-Ch (η2 = 0.542), HDL-Ch (η2 = 0.522), LDL-Ch (η2 = 0.587), T (η2 = 0.603), IGF-1 (η2 = 0.512) and GH (η2 = 0.621). Thus, FFM significantly increased while TBF and BM decreased in comparison to pre-intervention levels. The analyzed results indicate that treatment or supplementation of individual hormone deficiencies can be a successful form of counteracting the aging process. Nevertheless, the effects of TT supplementation on the concentration of T as well as GH and IGF-1, requires further studies, especially in middle-aged and older subjects, along with different exercise programs. The analyzed results indicate that treatment or supplementation of individual hormone deficiencies can be a major form of counteracting the aging process.

Opis:
During the last sixty years, large collections of ichthyofauna, mainly isolated, microscopic, skeletal remains (ichthyoliths), from the Middle–Upper Devonian and Lower Carboniferous rocks of southern Poland have accumulated in the hands of Polish palaeontologists and in palaeontological institutions. Some parts of these collections were described in unpublished dissertations and others were published in dispersed papers, dealing mostly with selected regions or taxa. This review summarises the available data from the following regions: the Holy Cross Mountains, the Cracow Upland, the Sudetes and the Lublin Coal Basin (in the latter two cases, single localities). Altogether, 29 chondrichthyan species were identified and a few more still require classification. Of the Sarcopterygii, three species of onychodontiforms and one of the actinistians were found, in addition to a collection of dipnoans that was described much earlier. A few morphological types were distinguished among actinopterygian scales; otherwise the actinopterygian fossils are not referred to any lower-level taxon, and the same applies to the acanthodians. There were several attempts in the past to apply Polish ichthyoliths in biostratigraphy and palaeoecology, but after all these years, it appears that such propositions have only limited significance.

Opis:
The Lower Devonian of the Holy Cross Mountains is well-known in the field of vertebrate palaeontology but remains unrecognized as regards palaeoenvironmental reconstructions. We therefore analysed the spatial distribution and relative abundance of fossil vertebrates in this area within one time interval. The fauna from an Early Devonian (Emsian) siliciclastic bone-bearing breccia (the “Placoderm Sandstone”) exposed in four sections of the Łysogóry region and five sections of the Kielce region was analysed with respect to the frequency of the remains and their taxonomic affinity. The relative abundances of agnathans, acanthodians, placoderms, osteichthyans and chondrichthyans suggest more open marine conditions in the Łysogóry region and more terrestrial-influenced in the Kielce region during the Emsian. The results show that the average agnathan and acanthodian content of the Łysogóry region is significantly larger than that in the Kielce region. On the other hand, there are relatively fewer osteichthyans in the Łysogóry region and a significantly higher proportion of bony fishes was recorded in the fauna of the Kielce region. Placoderms are characterized by their generally similar frequency in both regions and from site to site in each of them, though a greater abundance was noted from the Kielce region. Likewise differences in the proportions of particular groups in the Kielce region suggest a large variety of marginal-marine environments under the influence of factors that might have included marine currents and variable conditions around a river mouth.

Opis:
This paper presents an empirical approach to the changes in motor skills of children who train sports swimming at the initial stage of school education in an annual training cycle. Swimming belongs to the disciplines in which training starts at the age of 6-7. The proper selection of candidates to train certain disciplines is a complex process as they should be chosen from a large population of children, both girls and boys, having specific somatic and motor characteristics which, developed in the long-term, will enable them to achieve sports mastery. The aim of the research was to define which changes in motor skills occur in girls who train sports Aim: swimming in an annual training cycle. The Subject group consisted of 85 girls aged 7 who attended four elementary schools in Szczecin, Poland. 36 of them belonged to the Swimmers group and they were all members of the Municipal Swimming Club (MKP) in Szczecin. The Control group consisted of 49 girls who attended the same elementary schools. All subjects took part in two examinations (carried out in the school year 2009/2010. Physical ability tests were conducted in gyms. Motor skills were assessed with EUROFIT Test Battery which is the most reliable and accurate tool according to scientific research. The research revealed changes in both groups (Sw, C) in terms of all eight tests. Examination II proved statistically significant improvement of results in both groups (Sw, C) in comparison to Examination I. Changes between Examination I and Examination II results were most visible in the Swimmers groups in terms of balance, agility, static strength, functional strength and agility run. Changes between Examination I and Examination II were similar in both groups (Sw, C) in terms of speed of limb movement, explosive strength and torso strength. Progressive changes in motor skill of subjects are a positive phenomenon in the physical development of a child. Swimming training resulted significantly in positive changes in terms of motor skills of subject who were at the initial stage of swimming trainings, compared to their non-training peers. Participation in organized, regular sports classes results in the development of motor (physical) skills of children.

The article presents selected issues related to the development and testing of the diagnostics systems dedicated for superconducting electromagnets. The systems were con- structed to assess the production quality of superconducting electromagnets of the SIS100 synchrotron, a new accelerator being built as part of the Facility of Antiproton and Ion Re- search (FAIR). One of the systems is used for automatic checking of electrical connection parameters and the continuity of electric circuits. The role of the second device is to assess the quality of winding insulation and to estimate circuit parameters of electromagnet coils using the capacitor discharge method. The work presents measurements and analysis of current and voltage waveforms acquired during discharges on a magnet coil simulator and on the SIS100 main dipole electromagnet.

Opis:
Migrations form the size and structure of human resources in regions. For that reason they have not only a demographic but also a social and economic character. The existing research is often not enough due to a spatial, temporary and also a multidimensional character of this occurrence. The subject of this paper is to apply Structural Equation Modeling (SEM) concept for analysing the population migration phenomena considering the gravity model. This approach allows describing the social and economic situation in regions considering a set of correlated variables and it also allows determining its influence on migration flows. The first part of the article describes the construction and interpretation of the gravity model and the concept of the SEM model. In the second part the adopted research procedure and the research scope are presented. In the last part, the results of the investigation are explained. The strength and direction of the impact of the socio-economic development on the migration flows between subregions (NUTS 3) in Poland in the years 2008-2010 are discussed.
Migracje kształtują wielkość i strukturę zasobów ludzkich w regionach, mają więc wymiar nie tylko demograficzny, ale także społeczno-gospodarczy. Prowadzone badania obejmujące najczęściej analizę wskaźnikową, są często niewystarczające ze względu na przestrzenno-czasowy i wielowymiarowy charakter tego zjawiska. Celem artykułu jest propozycja zastosowania w analizie migracji metodologii SEM z uwzględnieniem modelu grawitacji. Takie podejście pozwala opisać sytuację społeczno-ekonomiczną regionów z wykorzystaniem zmiennych skorelowanych, a także określić jej wpływ na przepływy migracyjne. W pierwszej części artykułu omówiona jest konstrukcja i interpretacja modelu grawitacji oraz koncepcja modelu SEM. W drugiej części omówiono przyjętą procedurę badawczą oraz zakres badań. W ostatniej części zaprezentowano wyniki prowadzonej analizy. Określono siłę i kierunek oddziaływania poziomu rozwoju społeczno-ekonomicznego na przepływy migracyjne między podregionami (NUTS 3) w Polsce w latach 2008-2010.

Opis:
The paper makes an attempt to apply local indicators for categorical data (LICD) in the spatial analysis of economic development. The first part discusses the tests which examine spatial autocorrelation for categorical data. The second part presents a two-stage empirical study covering 66 Polish NUTS 3 regions. Firstly, we identify classes of regions presenting different economic development levels using taxonomic methods of multivariate data analysis. Secondly, we apply a join-count test to examine spatial dependencies between regions. It examines the tendency to form the spatial clusters. The global test indicates general spatial interactions between regions, while local tests give detailed results separately for each region. The global test detects spatial clustering of economically poor regions but is statistically insignificant as regards well-developed regions. Thus, the local tests are also applied. They indicate the occurrence of five spatial clusters and three outliers in Poland. There are three clusters of wealth. Their development is based on a diffusion impact of regional economic centres. The areas of eastern and north western Poland include clusters of poverty. The first one is impeded by the presense of three indiviual growth centres, while the second one is out of range of diffusion influence of bigger agglomerations.

Proper diet is a well-established factor influencing the effectiveness of training. to assess the knowledge of young sportspeople from Wrocław about sport nutritional strategies an online survey was distributed to Wrocław sport schools and clubs. the respondents were asked to answer questions regarding their sport activity, diet and the knowledge of nutrition strategies. the answers were then compared with the recommended strategies of international Society of Sports Nutrition (iSSN) and other research on this topic.147 answers were analyzed. 38% of the respondents modified their diet due to training. their most popular strategy was an additional pre-workout meal. in the group that did not modify the diet, the majority (82%) heard of some sport nutrition strategy. 52% of the respondents consumed a protein peri-workout meal. estimated 30% consume the amount of protein recommended by iSSN. Percentage of young sportspeople adjusting diet to training seems to be low, taking into account both established importance of such proceedings and awareness of sport nutrition strategies in this group. interestingly, more men than women do so. Group of respondents following well-documented iSSN recommendations is comparably modest. Perhaps the topic of nutrition strategies should be given more emphasis in schools and sport associations.

Opis:
Podczas blisko trzyletnich badań nad rozkładem mchu torfowca na torfowisku przejściowym oraz w borze bagiennym w północno-wschodniej Polsce zaobserwowano kolonizację materiału roślinnego w woreczkach ściółkowych przez silnie zmykoryzowane korzenie. Procentowa zawartość tych korzeni, wyrażona jako stosunek ich suchej masy do suchej masy rozkładających się szczątków roślinnych, generalnie zwiększała się wraz z upływem czasu w borze bagiennym, natomiast w przypadku torfowiska przejściowego nie wykazała wyraźnych tendencji; z racji niewielkiej liczby powtórzeń zaobserwowane różnice nie były jednak istotne statystycznie. W materiale roślinnym rozkładającym się na torfowisku przejściowym odnotowano obecność dwóch morfotypów korzeni wrzosowatych oraz dwóch morfotypów korzeni ektomykoryzowych, natomiast w borze bagiennym odnotowano jeden morfotyp korzeni wrzosowatych i 9 morfotypów korzeni ektomykoryzowych. Tylko jeden morfotyp wrzosowatych i jeden ektomykoryzowy były odnotowane w obu typach siedlisk; różnice wynikały z zasadniczych różnic w składzie zbiorowisk roślinnych pomiędzy badanymi powierzchniami. Większość (7 z 10) morfotypów ektomykoryz pojawiła się tylko raz podczas całego okresu trwania eksperymentu. Badania molekularne uzyskanych morfotypów powiodły się jedynie w siedmiu przypadkach: zidentyfikowano jeden gatunek tworzący mykoryzę erikoidalną, trzy gatunki tworzące ektomykoryzy (w tym jeden tworzący dwa morfotypy) oraz dwa gatunki grzybów wielkoowocnikowych znanych jako saprotrofy, prawdopodobnie wtórnie infekujących korzenie. Sekwencje uzyskane z pozostałych badanych morfotypów należały do grzybów mikroskopijnych najprawdopodobniej kolonizujących korzenie jako saprotrofy lub endofity. Pomimo że badania niniejsze stanowią jedynie szkicowe studium, to jednoznacznie wskazują na możliwość udziału grzybów mykoryzowych w procesach rozkładu materii roślinnej w ekosystemach torfowiskowych.
During a 35-month study on the decomposition of Sphagnum moss litter in poor fen and pine bog forest, an intensive colonization of litter-bags by mycorrhizal roots was observed during the decomposition process. Content of mycorrhizal roots in litter-bags, expressed as % mass of roots, was generally increasing during the decomposition in pine bog forest, and fluctuating during decomposition on poor fen, although in both cases the results were statistically insignificant. Two morphotypes of ericoid roots and two morphotypes of ectomycorrhizal roots were recorded from litter-bags on poor fen during the decomposition experiment, while in pine bog forest one morphotype of ericoid and nine morphotypes of ectomycorrhizal roots were recorded. Molecular identification of mycorrhizal roots succeeded only in the case of one ericoid and six putatively ectomycorrhizal morphotypes. Most morphotypes were recorded only once during the whole 35-month decomposition period, and only one ericoid and one ectomycorrhizal morphotypes were shared between the poor fen and pine bog forest communities.

Opis:
The objective of the article was to re-define the bipolar metropolitan area within the area of the Kujawsko-Pomorskie region (NUTS 2). Concentration of metropolitan features, as well as socio-economic situations of its communes (NUTS 5) in 2011, and also the dynamics of communes’ development in the period 2009-2011 were considered in the procedure of delimitation. Bydgoszcz and Toruń, as the economically strongest cities in the region, were established as the dual core of the bipolar metropolitan area. It was assumed that the determined metropolitan area would cover the best developed and the fastest developing communes which met the following criteria of a metropolitan area: neighbourhood, continuity, compactness, maximum distance and population. The development levels of the communes were determined with the use of syn-thetic measure. Its values were calculated considering the economic (e.g. the amount of income) and also social (e.g. unemployment) aspects of regional devel-opment, as well as features typical of metropolitan areas, such as: well-developed sectors of R&D, knowledge-based economy and serving superior services. In the research, linear arrangement methods classifying as taxonomic tools of multivari-ate data analysis was applied. The metropolitan area resulting from the research (BipOM) slightly differs from the Bydgoszcz-Toruń Metropolitan Area (B-TOM) which was formally ap-pointed in 2005 and composed all of the communes located within the area of the Bydgoski and Toruński districts (NUTS 4). Chełmża and Koronowo, as the less developed communes of the districts, were excluded from the new metropolitan area, while the communes of Ciechocinek, Nakło and Unisław, belonging to the neighbouring districts of the region, were included in the BipOM due to their significant level of regional development and its dynamics. Furthermore the Inowrocław district (bordered on the BipOM) was identified as the prospective candidate for the BipOM, due to the fact that its communes demonstrate a high potential for regional development.
