The funeral live : political ritual and media event

The article presents short but multi-faced of events surrounding the funeral of President Lech Kaczyński. Based on this example, the author considers issues concerning the political ritual and the media event. Also, the funeral is described as a performance following a specific scenario. The analysis was based on the material available in the media and the author’s personal observations

Stress conditions affect the immunomodulatory potential of Candida albicans extracellular vesicles and their impact on cytokine release by THP-1 human macrophages

Human immune cells possess the ability to react complexly and effectively after contact with microbial virulence factors, including those transported in cell-derived structures of nanometer sizes termed extracellular vesicles (EVs). EVs are produced by organisms of all kingdoms, including fungi pathogenic to humans. In this work, the immunomodulatory properties of EVs produced under oxidative stress conditions or at host concentrations of $CO_{2}$ by the fungal pathogen Candida albicans were investigated. The interaction of EVs with human pro-monocytes of the U-937 cell line was established, and the most notable effect was attributed to oxidative stress-related EVs. The immunomodulatory potential of tested EVs against human THP-1 macrophages was verified using cytotoxicity assay, ROS-production assay, and the measurement of cytokine production. All fungal EVs tested did not show a significant cytotoxic effect on THP-1 cells, although a slight pro-oxidative impact was indicated for EVs released by C. albicans cells grown under oxidative stress. Furthermore, for all tested types of EVs, the pro-inflammatory properties related to increased IL-8 and TNF-$\alpha$ production and decreased IL-10 secretion were demonstrated, with the most significant effect observed for EVs released under oxidative stress conditions

Funeral of president Lech Kaczyński: ritual, media, myth.

Praca jest wieloaspektowym spojrzeniem na wydarzenia związane z pogrzebem prezydenta Lecha Kaczyńskiego. Na przykładzie tego pogrzebu rozpatrywane są kwestie dotyczące rytuału, rytuału politycznego, wydarzenia medialnego i mitu. Autorka opisuje pogrzeb również jako swoiste widowisko podporządkowane scenariuszowi. Praca jest próbą pokazania, jak mocno wpisane w znane już wzorce, są zdarzenia przedstawiane w mediach jako niezwykłe i niepowtarzalne. Analiza pogrzebu została oparta na materiałach dostępnych w mediach oraz osobistej obserwacji autorkiThe thesis presents a multi-faceted analysis of events surrounding the funeral of President Lech Kaczynski. Based on this example, the author considers issues concerning the ritual, the political ritual, the media event and the myth. Also, the funeral is described as a performance following a specific scenario. The thesis also attempts to illustrate how events depicted by the media as unusual or unique are deeply rooted in previously known patterns. The analysis was based on the material available in the media and the author's personal observations
