    Opis:
    In this paper, we discuss the presence of community gardens in urban spaces and the types of activities performed there, using the city of Poznań as a case study. First, based on interviews with representatives of selected non-governmental organisations, analyses of available Internet sources as well as our own field research, cartographic and photographic documentation, we identify community gardens in the space of the city and explore their formation process. In the course of our study we also concentrate on the type of garden location. In addition, we devote our attention to the gardens which have disappeared from the fabric of the city. Our study reveals that community gardens currently operating in Poznań are established in non-central locations. These gardens are scattered in various parts of the city. Only in the Łazarz district there are two community gardens. Most frequently, community gardens are established on plots between old blocks of flats and tenement houses. Two gardens are located on underdeveloped greenery near the Warta River and in two city parks. A detailed examination of the events held in the community gardens in the Łazarz district in the years 2014–2017 shows that they had a very diversified character. Both of them turned out to be multifunctional, i.e. hosted meetings devoted to agriculture and horticulture, environmental education, artistic events, DIY and recreation. However, the percentage of events in the structure of the meetings organised in the gardens differed considerably.

    Opis:
    Expression of p16 protein, intragenic mutations of CDKN2A and hypermethylation of CDKN2A promoter region in 41 sporadic primary uveal melanomas were studied. There were 2 cases of spindle cell B histological type, 11 of A + B and 28 of mixed type. All melanomas infiltrated sclera but in 28 cases infiltration was superficial while in 13 profound. In 7 cases the tumor infiltrated the optic nerve. Expression of p16 was studied by immunohistochemistry and recorded by assessment of the proportion of positive tumor cells and staining intensity. Results were expressed as staining index (IRS). Intragenic mutations were studied by PCR-SSCP followed by sequencing, while hypermethylation of the promoter region by CpG methylation assay. In 15% of cases less than 10% of melanoma cells were p16 positive, in 70% of cases less than 50% of cells, while in 7% more than 80% of cells stained for p16 (mean IRS for all cases was 4.87 ± 2.43). In B type the IRS was 8.5 ± 0.7, in A + B type 6.0 ± 2.1 and in the mixed type 4.17 ± 2.43 (differences statistically significant). In melanomas profoundly infiltrating sclera mean IRS was 4.16, while in those infiltrating optic nerve 3.71 (statistically not significant). Analysis of the intragenic mutations revealed in two patients a GAC/GAT substitution in codon 84 - a silent mutation. No hypermethylation of the CpG island of the p16 promoter region was found. In conclusion, we found that the degree of p16 expression is related to the histological type of tumor but not to the histological indicators of tumor invasiveness and that intragenic mutations and promoter hypermethylation are not major mechanisms of p16 inactivation in sporadic uveal melanoma.
