Procrastination and well-being among elderly people

Celem pracy było zbadanie zależności pomiędzy prokrastynacją a odczuwanym dobrostanem życiowym wśród osób po 60. roku życia oraz sprawdzenie jej w grupie osób mieszkających w domach i w grupie pensjonariuszy Zakładu Opiekuńczo-Leczniczego. W badaniu użyto polskich adaptacji skróconej wersji kwestionariusza do badania prokrastynacji Pure Procrastination Scale P. Steel’a oraz pełnej wersji kwestionariusza do badania dobrostanu Psychological Well-Being Scale C. Ryff. Ponadto, za pomocą pytań własnego autorstwa oceniano subiektywne zdrowie. Zbadano łącznie 60 osób z podziałem na dwie grupy: osób mieszkających w domach oraz pensjonariuszy Zakładu Opiekuńczo-Leczniczego w Krakowie. Z analiz międzygrupowych wskaźników zdrowia, dobrostanu i prokrastynacji wynika, iż grupa osób mieszkających w domach cechuje się wysokim wynikiem oceny zdrowia, grupa pensjonariuszy Zakładu Opiekuńczo-Leczniczego natomiast, wysokim wynikiem na skali dobrostanu. Nie zanotowano różnic między grupami w zakresie zjawiska prokrastynacji. Stwierdzono, iż wyższe wyniki w zakresie prokrastynacji umiarkowanie korelują z niższymi wynikami w zakresie dobrostanu życiowego. Wystąpiły także różnice międzypłciowe w zakresie tejże zależności. Dodatkowo wskazano, iż wysokie wyniki na skali zdrowia nie determinują wysokich wyników na skali dobrostanu.The aim of this study was to investigate how procrastination impacts on subjective well-being in elderly and how this relationship differs among the group of elderly people living in homes and residents of the House of Care and Treatment. The short version of the Pure Procrastination Scale by P. Steel and the full version of the Psychological Well-Being Scale by C. Ryff have been used. Additionally, three questions of own authorship related to subjective health has been asked. A total of 60 people were examined divided into two groups: elders living in their homes and residents of the House of Care and Treatment in Cracow. The intergroup analysis of health, well-being and procrastination indicators shows that the group of people living in homes is characterized by a high score of health assessment, while the group of residents of the House of Care and Treatment is characterized by a high score on the scale of well-being. There were no differences between the groups in terms of procrastination. It was found that higher procrastination results moderately correlate with lower results in terms of well-being. Differences between gender were additionally found. Moreover, it was pointed out that high results on the health scale do not determine high results on the scale of well-being

Vimentin cytoskeleton architecture analysis on polylactide and polyhydroxyoctanoate substrates for cell culturing

Polylactide (PLA), widely used in bioengineering and medicine, gained popularity due to its biocompatibility and biodegradability. Natural origin and eco-friendly background encourage the search of novel materials with such features, such as polyhydroxyoctanoate (P(3HO)), a polyester of bacterial origin. Physicochemical features of both P(3HO) and PLA have an impact on cellular response 32, i.e., adhesion, migration, and cell morphology, based on the signaling and changes in the architecture of the three cytoskeletal networks: microfilaments (F-actin), microtubules, and intermediate filaments (IF). To investigate the role of IF in the cellular response to the substrate, we focused on vimentin intermediate filaments (VIFs), present in mouse embryonic fibroblast cells (MEF). VIFs maintain cell integrity and protect it from external mechanical stress, and also take part in the transmission of signals from the exterior of the cell to its inner organelles, which is under constant investigation. Physiochemical properties of a substrate have an impact on cells’ morphology, and thus on cytoskeleton network signaling and assembly. In this work, we show how PLA and P(3HO) crystallinity and hydrophilicity influence VIFs, and we identify that two different types of vimentin cytoskeleton architecture: network “classic” and “nutshell-like” are expressed by MEFs in different numbers of cells depending on substrate features
