Pharmaceutical products containing non-steroidal anti-inflammatory drugs (NSAIDs) are among the most prescribed topical formulations used for analgesic and antirheumatic properties. These drugs must overcome the skin barrier to cause a therapeutic effect. Human skin has been widely used as a model to study in vitro drug diffusion and permeation, however, it suffers from many limitations. Therefore, to perform in vitro permeation test (IVPT), we used a Strat-M® membrane with diffusion characteristics well-correlated to human skin. This study’s objective was to optimize the IVPT conditions using Plackett–Burman experimental design for bio-predictive evaluation of the in vitro permeation rates of five non-steroidal anti-inflammatory drugs (diclofenac, etofenamate, ibuprofen, ketoprofen, naproxen) across Strat-M® membrane from commercial topical formulations. The Plackett–Burman factorial design was used to screen the effect of seven factors in eight runs with one additional center point. This tool allowed us to set the sensitive and discriminative IVPT final conditions that can appropriately characterize the NSAIDs formulations. The permeation rate of etofenamate (ETF) across the Strat-M® membrane was 1.7–14.8 times faster than other NSAIDs from selected semisolids but 1.6 times slower than the ETF spray formulation.

Background: Obesity and overweight affect a large proportion of the world’s population. Increasingly, this problem can be observed among young adults. The aim of the study was to identify the motivations and barriers to healthy eating habits among young Poles, the relationship between physical activity and healthy eating and the impact of healthy eating on the body composition of the young. Methods: The method used in the research was a diagnostic survey using direct personal interviews. The research was conducted in the years 2016–2019 on a group of 399 young Poles aged 18–26. Their body composition was analyzed by determining resistance and reactance using the biological impedance method, with a TANITA SC-330ST Body Composition Analyzer. Results and conclusion: The main reasons for healthy eating among young Poles are the intent to follow a doctor’s recommendations, to lose weight and to live a healthy lifestyle and to follow a trend. On the other hand, the largest barriers to proper nutrition are: lack of time to prepare healthy meals and of financial resources, inability to prepare meals and limited knowledge of the principles of healthy eating. The eating behavior varied significantly in relation to the physical activity of the respondents. Active people’s eating habits were the best, and those of sedentary people the worst. Healthy eaters also had normal body composition indicators (adipose tissue level, BMI, body type). Young adults should be educated on the principles of healthy eating and have access to healthy food in canteens and vending machines, both at work and at university.

Lubelszczyzna posiada bogatą historię współistnienia i przenikania się różnych tradycji, kultur i religii, świadkami wielokulturowej przeszłości tych ziem są miasta i miasteczka. Małe miasta Lubelszczyzny borykają się obecnie z różnorodnymi problemami przestrzennymi, które związane są m.in. z organizacją i rewitalizacją przestrzeni publicznych, postępującym rozproszeniem zabudowy czy zmianami w rozwiązaniach układów komunikacji. Celem opracowania jest przedstawienie problematyki dotyczącej kształtowania krajobrazu oraz rewitalizacji małych miast Lubelszczyzny na przykładzie Frampola.

The study objective was to assess the impact of the vegetative shoots of the lawn cultivars of Poa pratensis (one of the most valuable lawn grasses), cut and left on the lawn surface, on the species composition and overwinter survival of a lawn. The investigation was conducted in a field experiment. Each cultivar was sown in monoculture, on microplots covering 1 m2 each. In the control objects, the cut biomass was removed immediately after the cutting. The investigation showed that ‘Bila’ had the strongest negative impact on the share of sown lawn grass cultivars (sensitivity to the biomass of the same cultivar remaining after cutting). The smallest share of other, unsown grass species in objects where the cut biomass remained was observed in lawns with ‘Nandu’ and, in the case of dicotyledons – with ‘Bila’. The biomass left on the lawn surface after cutting did not have a significant influence on the overwinter survival of the plants. The negative impact of P. pratensis biomass, both on the sown cultivars and other groups of plants, can indicate its allelopathic properties. Therefore, the grass of this species should not be left on the lawn after cutting. The aboveground biomass cut and left on the lawn surface was shown to have a clearly varied influence on the soil pH: in the case of the ‘Ani’ and ‘Bila’ cultivars, the influence was unequivocally negative. In addition, the biomass of these cultivars did not result in significantly increased levels of assimilable forms of phosphorus, potassium and magnesium in the soil.

The results of the research devoted to the change of the biological composition of the soil under the conditions of activation of microbiological vital activity and increase in the number of earthworms in the technology of spring barley cultivation are presented. It was found that the organic system of growing crops against the background of manure, cereal straw and green manure in comparison with the organo-mineral system obtained a positive dynamics of decomposition of linen tissue and the development of earthworms in the soil.The highest grain yield was formed by agrocenosis of spring barley with the introduction of Lancelot 450 WG – 0.033 kg·ha–1 + Axial 50 EC – 1 dm3·ha–1 (tube exit phase) – 4900 kg·ha–1 and 4700 kg·ha–1 for organo-mineral and organic fertilizer systems in accordance.

A contemporary look at modernism from the perspective of landscape architecture, superbly illustrated. The authors describe modernism considering its today’s viewers: theoreticians, architects and students who create space as well as the “consumers” of modernist cities, districts and housing estates, pointing at the relative ambiguity of the phenomenon. They also attempt to answer the question concerning the future of modernism. The aim of the conducted research was to show – in the context of contemporary reception of modernism – its ideas, forms and meaning which can be of use in creating the optimal space between buildings. The authors employed various research methods, used in landscape architecture, urbanism, environmental psychology, sociology, art, social communication and media.

W artykule przedstawiono warunki występowania wód leczniczych na Dolnym Śląsku zwracając szczególną uwagę na specyfikę tego obszaru. Omówiono wielowiekową historię wykorzystywania dolnośląskich wód leczniczych oraz obecny stan udokumentowania ich zasobów. Na Dolnym Śląsku występuje wiele rodzajów wód leczniczych, m.in. szczawy, wody radonowe i lecznicze wody termalne, a także ich mieszaniny (szczawy termalne, szczawy radonowe). Wody te zawierają także szereg składników swoistych, takich jak żelazo, fluorki, kwas metakrzemowy i siarkowodór. Złoża tych wód w największym nagromadzeniu występują w Sudetach. Na obszarze bloku przedsudeckiego i monokliny przedsudeckiej są mniej liczne. Aktualnie na Dolnym Śląsku znajduje się 20 złóż wód leczniczych, z czego w 2020 r. wody wydobywano z 10 z nich. Wody lecznicze Dolnego Śląska są wykorzystywane głównie w balneoterapii i rozlewnictwie, także w rekreacji oraz do wytwarzania kosmetykówi produkcji naturalnego CO2. W artykule poruszono także najważniejsze zagadnienia związane z dokumentowaniem zasobów eksploatacyjnych ujęć wód leczniczych na Dolnym Śląsku.
