Mixture model of NMR - its application to diagnosis and treatment of brain cancer
Franciszek Binczyk, Rafa Tarnawski, Joanna Polańska
Archives of Control Sciences , 2010, DOI: 10.2478/v10170-010-0026-3
Abstract: Nuclear Magnetic Resonance (NMR) is widely used technique in cancer diagnosis and treatment planning. It is employed to search for the high concentration regions of particular metabolites, which are directly related to the concentration of cancer cells. NMR signal maybe be characterized by a set of peaks which are representation of every distinct metabolite. Area under peak must be calculated in order to obtain proper information about metabolite amount. Commercially available software allows for the analysis of one-peak-in-time only. The proposed technique, based on Gaussian Mixture Model (GMM), allows for modeling all-peaks-in-time, and corrects after the neighboring peaks giving more accurate estimates of metabolite concentration. The resulting software processes NMR signal from the very beginning up to the final result, which is given in a form of so called metabolite map.

Abstract: Introduction:The aim of this work was a quantitative and qualitative assessment of a selected part of the microcirculation in children with diabetes type 1 using videocapillaroscopy technique.Material/Methods:The authors tested a group consisting of 145 children (70 boys, 75 girls) diagnosed and treated for diabetes type 1 in the Diabetic Clinic of GCZD in Katowice for at least one year. The study included history, clinical examination (including dermatological examination) and videocapillaroscopy. Capillaroscopy, a non-invasive, painless and easily repeatable test, was performed using videocapillaroscopy with digital storage of the obtained images. All nailfolds were examined in all children using videocapillaroscopy, and the obtained images were assessed quantitatively and qualitatively for changes in capillary loops in the tested children according to the defined diagnostic procedure.Results:The analysis of capillaroscopic images described selected quantitative and qualitative characteristics. The conducted analysis showed an increase in the number of capillaries and their elongation, the presence of megacapillaries and Raynaud loops, which were accompanied by an intensive red background, indicating possible neoangiogenesis. The increase in the number of capillaries, disturbances in distribution of capillaries and the presence of abnormal capillaries were correlated with the longer duration of diabetes. Raynaud loops were more frequently found in the cases of increased mean values of HbA1c. Higher values of HbA1c influenced the capillaroscopic images, mainly the number of vessels, including Raynaud loops.Conclusions:Videocapillaroscopy technique could be a useful tool to detect the early changes of microangiopathy in children with diabetes type 1.

Abstract: The aim of the study was to assess chosen factors of genetic susceptibility to DMT1: DRB1, DQB1, and TNF-α polymorphisms-308 (G/A) in children with DMT1 and their up-to-now healthy siblings. Then we tested whether the association between TNF-α genes and DMT1 is independent of HLA. 87 diabetic children, their 78 siblings, and 85 persons from healthy control group were followed up. The highest risk of DMT1 was connected with alleles: DRB1*0401 (OR = 3.39; CI: 1.55–7.41), DRB1*0301 (OR = 2.72; CI: 1.48–5.01), DQB1*0201 (OR = 4.04; CI: 2.17–7.52), DQB1*0302 (OR = 5.08; CI: 2.54–10.14), and TNF-α-308 A allele (OR = 2.59; CI: 1.23–5.44). Moreover linkage disequilibrium for TNF-α-308 A allele with DRB1*0301 and DQB1*0201 was observed in both diabetic children and their siblings. Diabetic children and their siblings present similar genetic risk factors for DMT1. The association between TNF-α-308 A allele and DMT1 is dependent of HLA-DRB1 and DQB1 alleles.

International Journal of Occupational Medicine and Environmental Health , 2007, DOI: 10.2478/v10001-007-0037-x
Abstract: Objectives: The study objective was to evaluate an association between selected work-related and socio-economic factors and tobacco smoking among economically active individuals. Materials and Methods: The study was conducted among randomly selected residents of the city of ód (n = 598) aged 25-64 years. The smoking status was determined based on questionnaire data. Logistic regression models were applied to assess the factors related to the smoking habit. Results: Multifactorial logistic regression analysis indicated that low level of education, lack of recreational physical activity and medium/heavy physical work were significant determinants of smoking. Conclusions: Prevention programs aimed at improving health-related habits and behaviors should be addressed to all economically active individuals, particularly to those who perform medium and heavy physical work. An antismoking intervention should be tailored to individual needs, taking into account the educational level.
On Bridge Requirements in English
Joanna miecińska
Poznań Studies in Contemporary Linguistics , 2007, DOI: 10.2478/v10010-007-0008-1
Abstract: A minimalist analysis of island conditions and bridge requirements on wh-movement in English is proposed. It has been traditionally assumed within the generative framework that wh-movement is impossible or degraded across a range of structurally analysable configurations (islands) and acceptable elsewhere (bridges). Structures meeting the configurational requirements but nevertheless having a degraded grammaticality status (non-bridge constructions) were, not rightly, banished from the scope of syntactic research proper. With the advent of minimalism, a syntactic account of non-bridge constructions can be achieved. The paper employs and modifies ideas from, among others, Chomsky (1998 and 1999), Uriagereka (1999), and Franks (2000) to show that the time of merging of a given constituent is crucial for its islandhood. Thanks to a minimalist perspective taken here, unification of bridge and island conditions seems possible. Also, a reinvestigation of Erteschik's (1973) verb typology is offered with an interim conclusion that that factivity of verbs with complement clauses is a decisive factor for their island status.

Abstract: Dans les années 1930, Milan Pi út (1908-1984) présenta Slovenské iskrice (L’étincelle slovaque, 1856), poème jusqu’alors inconnu de Samo Bohdan Hroboň (1820-1894), en le pla ant dans le contexte du messianisme. Le critique et historien de la littérature slovaque de renom voulait ainsi exprimer que le messianisme slovaque loin d’être un extrémisme poétique avait en réalité imprégné toute une génération et lui avait fourni un soutien spirituel fondamental à une époque de magyarisation a...
The influence of economic and marketing factors on market behaviour of young consumers
Joanna Kicińska
Journal of Agribusiness and Rural Development , 2010,
Abstract: Due to the high value of the market of young consumers in Poland, both children and the youth constitute a very attractive segment of consumers. A very high rate of them have their own money. This article aims at evaluation of influence of economic and marketing determinants on market choices of teenagers. The research shows that the determinants are of a crucial significance; the most important being the quality of goods and their prices. The most popular source of income for teenagers is the pocket money received from their parents. Young consumers use different ways of promotion and ways of sales support. Professional service and the possibility of the return of the product are the most appreciated assets of trading points.
The influence of psychological and social factors on market behaviour of young consumers
Joanna Kicińska
Journal of Agribusiness and Rural Development , 2009,
Abstract: This article presents the results of research concerning the influence of psychological and social factors on market behaviour of young consumers in Poland and in the world. The research confirms that children and the youth constitute a separate market group and the age determines their market independence. Making decisions regarding purchase of goods young consumers tend to ask for help those whom they rely on, which is connected with their small market experience. The need to do market shopping is mainly influenced by the feeling of lack of young people and then parents’ suggestions and peers’ advice. Young consumers buy goods also on impulse. It regards mainly comestibles. Fashion is the most important for children and the youth in case of clothing articles and shoes. The factor of market novelty is not a determinant of a big importance in the choice of goods purchased by children and the youth.

Abstract: The aim of this project was to evaluate the effect of intensive individual anti-smoking counselling among pregnant women from a Polish urban community with a large representation of socially underprivileged women. The study was conducted between 1 December 2000 and 31 December 2001. Out of 204 women who were asked to take part in a midwives-assisted program of educational counselling to stop smoking, 152 (74.5%) agreed to participate. The intervention program included four visits of a midwife trained in smoking cessation techniques to the home of a smoking pregnant woman. The control group were 145 pregnant women who on the first visit to a maternity unit received only a standard written information on the health risk from maternal smoking to the foetus. The percentage of pregnant women who quitted smoking during the project was 46.1% in the intervention group and 23.4% among the controls (p < 0.001). After combining the intervention group with the women who refused to participate in the project, the rate of quitting was 36.3%, still significantly higher than in controls (p = 0.01). The strongest influence of the intervention was found among women smoking more than 5 cigarettes/day. Women covered by the intervention programme, who reported smoking in previous pregnancies, were found to quit smoking to a much higher extent than the controls with a similar background. Such pattern was also observed for women whose husbands were smokers. The benefits of the intervention, especially for the socially underprivileged women, seem to result from an increased proportion of subjects who undertook a quitting attempt, rather than the effectiveness of these attempts. In the intervention group, among the subjects who did not manage to quit smoking during pregnancy, the number of women who at least slightly reduced their smoking rate was twice as high as in the controls.
