    Opis:
    The goal of this study is to evaluate the relationship between the time spent in front of a computer or TV and eating habits in kindergarten children. The study was conducted in May and September 2012 in two kindergartens in Krakow (n=61) and in a kindergarten in Podłęże, a village near Krakow (n=34). The average age of the studied children was 5.02±1.17. 40 parents of boys and 55 parents of girls took part in the study. The differences in responses related to gender and place of living were checked. The analyses of correlations among particular factors, including BMI, were conducted by means of the Spearman rank. Most of the kindergarten children (60%) spent an hour or less in front of TV. No relation between the time spent in front of TV or computer and gender or place of living or BMI interpretation was noticed. The time devoted to watching TV was connected with the frequency of snacks and fast-food consumption. The higher the education of mothers the less frequently children eat in front of TV. The frequency of sweetened beverages was also linked with the time spent in front of a computer. The relation between time spent in front of TV or computer and frequency of high energy food consumption among children was confirmed in the study. An effort should be made to educate parents about probable increased risk of children’s obesity connected with watching media

    Opis:
    Artykuł podejmuje zagadnienie występowania ADHD wśród dorosłych kobiet i mężczyzn. W celu wstępnego rozeznania na temat aktualności i wagi tego problemu u osób rozpoczynających dorosłe życie przeprowadzono badania pilotażowe. Przebadano 331 osób (204 kobiety i 127 mężczyzn) – studentów II roku różnych kierunków na Uniwersytecie Jagiellońskim. Z przeprowadzonych analiz wynika, że blisko 1/4 (72) studentów obu płci (18% spośród kobiet i 28% w grupie mężczyzn) wykazuje objawy zaburzeń związane z ADHD, co znacznie utrudnia im funkcjonowanie we wszystkich sferach życia codziennego (nie tylko nauki) w porównaniu z osobami zdrowymi. Na tej podstawie można wnosić o potrzebie kontynuacji badań empirycznych nad ADHD u dorosłych i opracowania skutecznych form pomocy dotkniętym tym zaburzeniem studentom.
    The article focuses on the issue of occurrence of ADHD amongadult men and women. A pilotstudy involving persons entering adulthood has been conducted as means of preliminary assesmentof currency and severity of the problem. 331 individuals (204 women and 127 men) who were 2ndyear students enrolled in various courses at the Jagiellonian University have been surveyed. Analysis of the gathered data reveals that nearly 1/4 (72) of students of both genders (18% of womenand 28% of men) exhibits symptoms of disorders related to ADHD severe enough to negativelyimpact all aspects of their lives, not merely studying. These findings suggest a need for continuation of empirical studies on adult ADHD and consequent development of effective means of helping the affected students.

    Opis:
    In quest of alternate, extradermal path of melanin transfer from skin to the visceral organs, we suggested that some portions of such melanin may be deposited in the spleen, which in young black C57BL/6 mice is often melanized. Here, we confirm these observation using young C57BL/6 female mice (up to 17 weeks) and show that this phenomenon cannot be observed in old animals where the hair cycle is not synchronized any more. The experiments were carried out both on spontaneous and depilation-induced hair cycle. We have checked it as a side-observation over many other experiments carried out on young and old C57BL/6 female mice (up to 2.5 years of life). The presence or absence of melanin in the spleens was checked macroscopically, and histologically by Fontana-Masson (FM) staining, and synchronization of the hair cycle - by standard histomorphometric analysis of the back skin hair follicles. In about 40% of old spleens black FM-stainable 'debris' could be found under closer histological examination. This study shows that, at least in part, the phenomenon of splenic melanosis in C57BL/6 mice can be correlated with the synchronized skin melanization parallel to the hair cycle progress, and that splenic melanin undergoes gradual degradation during the mouse life.

    Opis:
    Purpose: The authors analyze the decisions made from March to September 2020 which affected the functioning of Polish health care facilities. According to the authors, that period determined and significantly influenced the decisions taken by state authorities during the subsequent waves of the SARS-CoV-2 pandemic. Design/methodology/approach: The analysis of the issue presented in the paper will be a descriptive one. The research exploration will be carried out using the desk research method. Findings: Analyses of secondary and compilation documents showed that the authorities of the Republic of Poland were not prepared to manage the state in unprecedented conditions caused by the first wave of the pandemic, and the decisions taken at that time by public administration bodies were chaotic, not always well thought out and often influenced by public opinion. Originality/value (mandatory) The article can be considered original due to the fact that it combines an analysis of Polish legal acts issued during the first wave of the COVID-19 epidemic with, above all, an analysis of their social effects. The analyses showed that Polish authorities were not prepared for the pandemic crisis. The article is addressed to state administration employees as well as employees and students of universities with majors in national defense, public safety, medicine, medical rescue and public health. It may become a basis for developing legal acts of a preventive nature, which can be immediately applied in the event of another epidemic.

    Opis:
    Cancer chemotherapy is associated with serious side effects, including temporary hair loss and impairment of pigmentation. We suspect that ectopic melanin deposition occurring due to chemotherapy may add to these effects worsening the already unpleasant symptoms. We associated the ectopic occurrence of follicular melanin after chemotherapy with splenic melanosis - an interesting example of extradermal melanin localization - and we expected an increase in splenic melanin deposition after chemotherapy. Using the C57BL/6 murine model of synchronized hair cycle induced by depilation, we visualized splenic melanin by means of several histological and histochemical protocols of staining: hematoxylin and eosin, May-Grünwald-Giemsa and Fontana-Masson. Unexpectedly, the splenic deposition of melanin decreased due to application of cyclophosphamide (i.p. 120 mg/ kg body weight on day 9 post depilation). The drop was abrupt and lasted for at least 5 days (day 13-18 post depilation), as compared with normal hair cycle. Moreover, in mice with normal, depilation-induced hair cycle we observed a similar drop shortly before entering catagen (day 15 post depilation), followed by a slow and partial increase in splenic melanization up to day 27 post depilation in both groups. We conclude that cyclophosphamide negatively affects splenic melanization and/or extradermal transfer of ectopic melanin from the dystrophic hair follicles, but the most powerful down-regulator of splenic melanosis is normal and dystrophic catagen - the phase of hair follicle involution and re-modelling.

    Opis:
    The presence of melanin in spleens of black C57BL/6 mice has been known for long. Although its origin and biological functions are still obscure, the relation of splenic melanin to the hair follicle and skin pigmentation was suggested. Here, we demonstrated using for the first time electron paramagnetic resonance spectroscopy that black-spotted C57BL/6 spleens contain eumelanin. Its presence here is a "yes or no" phenomenon, as even in the groups which revealed the highest percentage of spots single organs completely devoid of the pigment were found. Percentage of the spotted spleens decreased, however, with the progress of telogen after spontaneously-induced hair growth. The paramagnetic properties of the spleen eumelanin differed from the hair shaft or anagen VI skin melanin. The splenic melanin revealed narrower signal, and its microwave power saturability betrayed more heterogenous population of paramagnetic centres than in the skin or hair shaft pigment. Interestingly, the pigment of dry hair shafts and of the wet tissue of depilated anagen VI skin revealed almost identical properties. The properties of splenic melanin better resembled the synthetic dopa melanin (water suspension, and to a lesser degree - powder sample) than the skin/hair melanin. All these findings may indicate a limited degradation of splenic melanin as compared to the skin/hair pigment. The splenic eumelanin may at least in part originate from the skin melanin phagocyted in catagen by the Langerhans cells or macrophages and transported to the organ.
