Opis:
The article "John Długosz about Hus and his views" is not limited to the observationsof the Polish chronicler about the Czech reformer and his teachings. The article also includes the stages of Poland's relationship with the Czechs in the 15th century. The division was made U. Borkowska and J. Nikodem. The text presents Długosz as a person with a negative attitude to the teachings of John Hus, it was related to the fact that the Czech preacher was considered a heretic. The article presents the events described by Długosz, among others the death of Hus, clashes between the Hussites and the troops of Sigismund of Luxemburg, or the arrival of the Czech legation to King Władysław Jagiełło.

Jan Długosz
Polish-Teutonic dispute
Opis:
For the present in the Annales point of view on the Polish-Teutonic dispute, the primary importance was the victorious ending of the Thirteen Years’ War, which Długosz had witnessed, and additionally – a decades-distance in time between the baptism of Lithuania and Samogitia as well as the Grunwald victory and Council of Constance, and the period of writing of the Annales. These two circumstances led the canon of Cracow to present the events from the perspective of the sustainability of the effects of Polish Christianization, as well as military and political successes, opening the history of Poland becoming more powerful and acceding to fulfill its historical mission in that part of Europe (“rampart”). From this perspective, the Polish-Teutonic dispute was significant, but belonged to the past. In Długosz’s depiction the durability of Lithuanian and Samogitian Christianization, which finalized Polish-Teutonic relations in the “christanitas”, resulted in focusing attention on territorial matters (Conciliar so-called legal process), and not on the issue of Christianization (Conciliar socalled doctrine process). For a historian, the most important matter is not missionary activity, but Teutonic aggression causing Polish territorial losses and The Recovery action. For Jan Długosz – a man of the late Middle Ages, the most important values were piety and patriotism. The first manifested itself in the vision of God punishing those who appropriate the property of others, and a God who is showing his mercy through the victorious for the Polish side result of Thirteen Years’ War. The value of the second manifested itself in making the interest of the Polish state, from public-law perspective, the most important criterion for assessing people and events. The outcome of these values was a two-fold depiction of the parties in the Polish-Teutonic conflict. This was reflected in the writings with the portrayal of the Teutonic Knights as insidious aggressors, of the judges adjudicating in their favor as being biased, and in criticizing Polish rulers and their advisers who abandoned efforts to recover lost lands. Another manifestation involved praising the rulers aiming at the recovery of losses, that is proceeding in accordance with the interests of Poland, and the depiction of so ruling judges as conscientious and reliable. The indicated twofoldedness was also reflected in Długosz’s account of peace treaties and verdicts.

Opis:
Structural motifs found in naturally occurring compounds are frequently used by researchers to develop novel synthetic drug candidates. Some of these new agents are hybrid molecules which are designed through a concept of combining more than one functional element. In this report, anticancer activity of new synthetic molecular hybrids, substituted 3-diethoxyphosphorylnaphtho[2,3-b]furan-4,9-diones and 3-diethoxyphosphorylbenzo[f]indole-4,9-diones, which integrate natural 1,4-naphtalenedione scaffold, present in several anticancer agents, with pharmacophoric phosphonate moiety, were tested against hepatocellular cell line HepG2. Cytotoxicity was examined using MTT assay. Two most potent compounds, furandione 8a and benzoindoldione 12a, which reduced the number of viable HepG2 cells with the IC50 values of 4.13 µM and 5.9 µM, respectively, were selected for further research. These compounds decreased the mRNA expression levels of several genes: Bcl-2, angiogenic vascular endothelial growth factor (VEGF), c-Fos, caspase-8 and increased the expression of Bax, caspase-3 and -9, c-Jun, p21, p53, as determined by quantitative real-time PCR. The ability of these compounds to induce apoptosis and DNA damage was studied by flow cytometry. The obtained data showed that the new compounds inhibited cell viability by increasing apoptosis and decreasing angiogenesis. Compound 8a was a much stronger apoptosis inducer as compared with 12a and strongly activated the intrinsic pathway of apoptosis, associated with the loss of mitochondrial membrane potential and changes in Bax/Bcl-2 ratio. These findings show that the synthetic hybrids combining 1,4-naphthalenedione system and phosphonic acid moiety display potential to be further explored in the development of new anticancer agents.

Opis:
At the beginning of the year 2016, the representatives of the Polish Radon Centre decided to organize proficiency tests (PTs) for measurements of radon gas and radon decay products in the air, involving radon monitors and laboratory passive techniques. The Silesian Centre for Environmental Radioactivity of the Central Mining Institute (GIG), Katowice, became responsible for the organization of the PT exercises. The main reason to choose that location was the radon chamber in GIG with a volume of 17 m3 , the biggest one in Poland. Accordingly, 13 participants from Poland plus one participant from Germany expressed their interest. The participants were invited to inform the organizers about what types of monitors and methods they would like to check during the tests. On this basis, the GIG team prepared the proposal for the schedule of exercises, such as the required level(s) of radon concentrations, the number and periods of tests, proposed potential alpha energy concentration (PAEC) levels and also the overall period of PT. The PT activity was performed between 6th and 17th June 2016. After assessment of the results, the agreement between radon monitors and other measurement methods was confirmed. In the case of PAEC monitors and methods of measurements, the results of PT exercises were consistent and confirmed the accuracy of the calibration procedures used by the participants. The results of the PAEC PTs will be published elsewhere; in this paper, only the results of radon intercomparison are described.

Opis:
The article describes three interlaboratory experiments concerning 222Rn determination in water samples. The first two experiments were carried out with the use of artificial radon waters prepared by the Laboratory of Radiometric Expertise (LER), Institute of Nuclear Physics, Polish Academy of Sciences in Kraków in 2014 and 2018. The third experiment was performed using natural environment waters collected in the vicinity of the former uranium mine in Kowary in 2016. Most of the institutions performing radon in water measurements in Poland were gathered in the Polish Radon Centre Network, and they participated in the experiments. The goal of these exercises was to evaluate different measurement techniques used routinely in Polish laboratories and the laboratories’ proficiency of radon in water measurements. In the experiment performed in 2018, the reference values of 222Rn concentration in water were calculated based on the method developed at LER. The participants’ results appeared to be worse for low radon concentration than for high radon concentrations. The conclusions drawn on that base indicated the weaknesses of the used methods and probably the sampling. The interlaboratory experiments, in term, can help to improve the participants’ skills and reliability of their results.
