    Opis:
    A formula of measures applied to assess the level of income inequality results from the intellectual basis on which this approach is founded. Our paper focuses on Generalized Entropy measures. The aim of our paper is two-fold. Firstly, it aims at presenting GE measures and discussing their properties, especially the property of additive decomposition. Secondly, the empirical aim is to assess the level of income inequality in Poland and to indicate its main determinants. In the study we use microdata obtained from EU-SILC that cover information about incomes received by individual household members in 2016. Five factors are chosen as the possible drivers of income inequality. The study proves the characteristics related to human capital are the most influential factors of income variability between households. The characteristics describing the composition of the household contribute to the overall level of inequality to a smaller extent.

    Opis:
    The aim of the paper was to assess the regional differentiation of the level of agriculture and its changes over time. Based on the synthetic measure of development the rankings of regions (provinces) were created. The objects were also classified and divided into groups of a similar level of agriculture. In addition, in order to identify the long-term tendency in this sector of economy, the process of -convergence of the level of agriculture has been studied. For the verification of hypotheses dynamic panel models were applied. All computations were performed in the Gretl, based on CSO data.

    Opis:
    The research discussed in the article concerned the level of development of agriculture in Poland. The main aim of the study was to verify the hypothesis of convergence of the economic size of farms. The analysis confirmed the existence of -convergence, however, showed no occurrence of σ-convergence and γ-convergence. Based on the results of the analysis of marginal vertical -convergence, Poland was divided into two clubs with different paths of development. In one of them the process of convergence was confirmed, but in the second one the phenomenon of divergence was revealed.

    Opis:
    The understanding of the spatial and temporal dynamics of farmland processes is essential to ensure the proper crop monitoring and early decision making needed to support efficient resource management in agriculture. By creating appropriate crop management strategies, one can increase harvest efficiency while reducing costs, waste, chemical spraying, and inhibiting the impact of biotic and abiotic factors on crop stress. Only reliable spatial information makes it possible to comprehend the influence of various factors on the environment. The main objective of the research presented in the paper was to assess the possibility of using maps of vegetation and soil indices, such as NDVI, SAVI, IRECI, CIred-edge, PSRI and HMSSI, calculated on the basis of images from the Sentinel-2 satellite, to qualitatively determine the increased amount of heavy metals in the soil in the areas of small agricultural plots around the Barania Góra nature reserve in Poland. The conducted pilot project shows that the spectral indices: NDVI, SAVI, IRECI, CIred-edge, PSRI, and HMSSI, calculated on the basis of images from Sentinel-2, have the potential to assess the content of nickel zinc, chromium and cobalt in the soil on agricultural plots. However, the confirmation of the obtained results requires continuation of the research.

    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.

    Opis:
    A protein kinase of 57 kDa, able to phosphorylate tyrosine in synthetic substrates pol(Glu4,Tyr1) and a fragment of Src tyrosine kinase, was isolated and partly purified from maize seedlings (Zea mays). The protein kinase was able to phosphorylate exogenous proteins: enolase, caseins, histones and myelin basic protein. Amino acid analysis of phosphorylated casein and enolase, as well as of phosphorylated endogenous proteins, showed that both Tyr and Ser residues were phosphorylated. Phosphotyrosine was also immunodetected in the 57 kDa protein fraction. In the protein fraction there are present 57 kDa protein kinase and enolase. This co-purification suggests that enolase can be an endogenous substrate of the kinase. The two proteins could be resolved by two-dimensional electrophoresis. Specific inhibitors of typical protein-tyrosine kinases had essentially no effect on the activity of the maize enzyme. Staurosporine, a nonspecific inhibitor of protein kinases, effectively inhibited the 57 kDa protein kinase. Also, poly L-lysine and heparin inhibited tyrosine phosphorylation by 57 kDa maize protein kinase. The substrate and inhibitor specificities of the 57 kDa maize protein kinase phosphorylating tyrosine indicate that it is a novel plant dual-specificity protein kinase.

    Opis:
    The purpose of this study was to analyze the indolic, phenolic, and fatty acid content and antioxidant activity of garlic sprouts growing in the dark and in the daylight. The pro- or anti-inflammatory properties of the garlic sprout extract were investigated by evaluating the cyclooxygenase-2 (COX-2), prostaglandin E synthase (cPGES), glutathione S transferase (GSTM1), nuclear factor NF-κB, peroxisome proliferator-activated receptors (PPARs), and aryl hydrocarbon receptor (AhR) protein levels in the RAW 264.7 cells activated with lipopolysaccharide (LPS). The highest amount of total indolic (73.56 mg/100 g f.w.) and phenolic compounds (36.23 mg/100 g f.w.) was detected in garlic sprouts grown in the daylight. Studies on antioxidant activity (the FRAP and DPPH method) of garlic sprouts showed that this activity is significantly higher for sprouts grown in full access to light when compared to those grown in the dark. In garlic sprout extracts, α-linolenic acid (ALA) was found to be in greater amount. COX-2 and cPGES level was lower when compared to LPS alone activated cells. After garlic extract treatment, higher level of GSTM1, PPARΥ, cytosolic p50 and p65 protein, as well as a lower NF-ĸB p50/p65 activity was noted in the RAW 264.7 cells which suggested PPARs and AhR transrepression mechanism of NF-ĸB signalling. The obtained results indicate Allium sativum sprouts are a rich source of n-3 fatty acids, indolic and phenolic compounds characterized by anti-inflammatory and antioxidative activity, which may support their high therapeutic and dietary potential.

    Opis:
    Metal responsive transcription factor 1 (MTF-1) is a zinc dependent transcription factor which is involved in the regulation of intracellular signaling pathways. MTF-1 regulates the expression of two streams of genes functioning in metal homeostasis and anti-oxidative response. MTF-1 acts in the process of binding of toxic metal ions in the cell, due to the activation of the expression of metallothioneins (MTs). Additionally, MTF-1 regulates transcription of genes involved in the sequestration of zinc and its intracellular transport. Disruption of zinc and MT homeostasis has an indispensable influence on the development of several pathological states. Moreover, by increasing MT activity, MTF-1 can effectively protect cells from oxidative and hypoxic stresses. The mechanism of MTF-1 action in cells includes the regulation of the proper immune response through activation/repression of anti- and pro-inflammatory cytokines. MTF-1 function in immune response is related to nuclear factor-κB (NF-κB) activity. Synthesis of insulin is also related to the activity of this transcription factor and zinc balance. Insulin transport also depends on zinc. In pancreatic β-cells, several types of the zinc transporters are found. Zinc transporters coordinated action is crucial for the synthesis and secretion of insulin. Disturbances in the regulation of signaling pathways connected with MTF-1 function can entail further alterations in zinc intracellular status and this growing imbalance can promote the pathophysiology of degenerative disorders.

    Opis:
    Guidelines for the pharmacotherapy of pain in cancer patients were developed by a group of 21 experts of the Polish Association for the Study of Pain, Polish Society of Palliative Medicine, Polish Society of Oncology, Polish Society of Family Medicine, Polish Society of Anaesthesiology and Intensive Therapy and Association of Polish Surgeons. During a series of meetings, the experts carried out an overview of the available literature on the treatment of pain in cancer patients, paying particular attention to systematic reviews and more recent randomized studies not included in the reviews. The search was performed in the EMBASE, MEDLINE, and Cochrane Central Register of Controlled Trials databases using such keywords as “pain”, “cancer”, “pharmacotherapy”, “analgesics”, and similar. The overviewed articles included studies of pathomechanisms of pain in cancer patients, methods for the assessment of pain in cancer patients, and drugs used in the pharmacotherapy of pain in cancer patients, including non-opioid analgesics (paracetamol, metamizole, non-steroidal anti-inflammatory drugs), opioids (strong and weak), coanalgesics (glucocorticosteroids, α2-adrenergic receptor agonists, NMDA receptor antagonists, antidepressants, anticonvulsants, topical medications) as well as drugs used to reduce the adverse effects of the analgesic treatment and symptoms other than pain in patients subjected to opioid treatment. The principles of opioid rotation and the management of patients with opioidophobia were discussed and recommendations for the management of opioid-induced hyperalgesia were presented. Drugs used in different types of pain experienced by cancer patients, including neuropathic pain, visceral pain, bone pain, and breakthrough pain, were included in the overview. Most common interactions of drugs used in the pharmacotherapy of pain in cancer patients as well as the principles for the management of crisis situations. In the final part of the recommendations, the issues of pain and care in dying patients are discussed. Recommendations are addressed to physicians of different specialties involved in the diagnostics and treatment of cancer in their daily practice. It is the hope of the experts who took part in the development of these recommendations that the recommendations would become helpful in everyday medical practice and thus contribute to the improvement in the quality of care and the efficacy of pain treatment in this group of patients.
