Opis:: Hormotila ramosissima Korš., a very rare in the world and poorly known species, have been found in peat bogs of Lower Silesia. The growth stages typical of this species but unknown so far, have been described and illustrated. It was found that this species has many features in common with the representatives of Volvocales, Tetrasporales, and chlorococcales. The regularly observed zoospores and hemizoospores, which accompanied the various developmental stages of that species, showed an internal structure of Chlamydomonas-type. Studies on Hormotila ramosissima were based on live material collected in ample quantities from peat bogs. The collected in this way repeatable and abundant data allowed to discuss problems concerning morphology, reproduction and development, as well as consider the taxonomic position this species.

Opis:: The diversity of cyanobacteria and algae from various microhabitats in Spitsbergen is comparatively well known. However, the relationships between environmental factors and the structure of microflora communities remain largely unclear. This study was conducted in Hornsund Bay, which exhibits large variability in the physicochemical characteristics of habitats, particularly with regard to the availability of nitrogen and phosphorus. This variability, to a large degree, is caused by seabird colonies, which fertilize nutrient-poor terrestrial ecosystems near their nesting areas. The large variations in ecological conditions and vegetation types in the study area aid assessment of habitats representing different combinations of factors potentially influencing the formation of cyanobacterial and algal assemblages. The aim of this study was to examine the influence of physicochemical parameters on the taxonomic composition and diversity of green algae and cyanobacteria (particularly the coccoid, oscillatorialean, and heterocystous taxa). The study encompassed two groups of habitats – soil surface habitats and water-saturated habitats, both characterized by diverse influences of seabird colonies, vegetation cover, and moisture. Our results showed that taxonomic diversity and composition of cyanobacteria and algae were mainly influenced by P–PO₄³⁻, N–NH₄⁺ and Ca²⁺ (soil surface habitats), and NO₃⁻, as well as moisture (index of wetness) and pH (water-saturated habitats). The variability of these physicochemical properties was largely due to the variability of the seabird colony influence. Taken together, our findings aid in understanding the processes of formation of phycoflora assemblages in Arctic tundra.

Opis:: Hygiene plays an important role in patients who use removable dentures. The proper way of cleaning and storage also provides better health of oral cavity tissues as well as for the remaining teeth. The research involved 162 patients, 133 women and 29 men, aged 60–90, with different levels of education, the majority with secondary education. All patients were using removable dentures. 85.8% declared earlier use of dentures, and a half of the patients had used dentures for no more than 7.5 years. A considerable percentage (33.95%) used dentures for the whole day. Storing in a container with fluid was used by 25.93% of the respondents. Over 70% used toothpaste to clean their dentures and about 14% immersed them in special preparations, e.g. CoregaTabs, while over 8% used soap. Among patients who cleaned their dentures, the majority cleaned them once a week (75%) and the minority – twice a week (25%). The greatest percentage of patients cleaned their dentures with a toothbrush and toothpaste, which is not recommended due to occurring microabrasions. It is recommended that patients should be educated regarding prosthesis hygiene and regular follow-ups.
