People have always been interested in discovering their past and seeking answers to their existential questions. Therefore institutions like museums, which collect exhibits related to the history and development of humans, have been known since antiquity. However, museology today has changed and is no longer confined to establishments related to popular fields like painting, sculpture and archaeology. Nowadays, there are also museums dedicated to medical sciences, which present the history of humanity in the sphere of its biological development. The Medical University in Wrocław can boast of several such establishments, although so far they have been treated as separate institutions. For this reason, the idea was created to combine them all into a single museum route, and to make it available to a broader visitor base. Thanks to this, people can view items from old and modern medicine practice located in many different sites, allowing them to deepen their knowledge and expand their interests. To make it easier for visitors to navigate through such a diverse complex, a special museum path has been created, along with a description of each location.
Objectives The objective of the study was to assess prenatal toxicity of N-methylaniline (NMA) administered by gavage to pregnant female rats. Material and Methods Pregnant female rats were administered N-methylaniline in corn oil by gavage at daily doses of 0.8 mg/kg of body weight (b.w.), 4 mg/kg b.w., 20 mg/kg b.w. and 100 mg/kg b.w. from implantation (the 5th day post mating) to the day prior to the scheduled caesarean section (the 20th day of pregnancy). General behavior, body weight, food and water consumption, hematological, biochemical analyses and pathomorphological changes of the dams were recorded. Results All the females survived until the end of the study. The test substance was toxic to pregnant females, even at the lowest of the used doses, i.e., 0.8 mg/kg b.w./day. Lower weight gain during pregnancy and significantly higher NMA-dose-dependent absolute weight of the organs were noted in the exposed females. The females from the groups exposed at doses of 20 mg/kg b.w./day and 100 mg/kg b.w./day developed anemia and showed higher concentrations of free thyroxine (FT3) and free triiodothyronine (FT4) thyroid hormones. Total protein concentration exhibited an increase in all the exposed groups of females. In the prenatal toxicity study, administration of N-methylaniline throughout the embryonic and fetal periods produced embryotoxic effects at doses ranging 4–100 mg/kg b.w./day. Conclusions Considering the data obtained in this study, it is reasonable to assume that N-methylaniline administered orally to pregnant rats is toxic for mothers even at a low dose of 0.8 mg/kg b.w./day. However, this dose was not associated with any significant effects to their offspring. This prenatal exposure level may be considered as no-observed-adverse-effect level (NOAEL) for the progeny and a dose of 4 mg/kg b.w./day as the lowest-observed-adverse-effect level (LOAEL) for the progeny.
Celem pracy było określenie wartości prognostycznej markerów stanu zapalnego u pacjentów z potrójnie ujemnym rakiem piersi. Zebrano dane dotyczące 143 chorych i oceniono używając testu chi-kwadrat, testu Wilcoxon–Mann–Whitney oraz regresji Coxa. Stwierdzono związek między wysokim poziomem stosunku neutrofilów do limfocytów, płytek do limfocytów, wskaźnikiem ogólnoustrojowej reakcji immunologiczno-zapalnej a miejscowym stopniem zaawansowania: guz (T3/T4) (P=0.0001, P=0.0198, P=0.0001), dodatnie regionalne węzły chłonne (P=0.0014, P=0.0075, P=0.0206). Wielowymiarowa analiza wykazała, że choroba rozsiana, gorszy stan sprawności oraz wysoki stosunek neutrofilów do limfocytów (Hazard ratio: 4.48 [2.05-9.80], P=0.0002; 2.23 [1.24-4.03], P=0.0010; 2.23 [1.24-4.03], P=0.0075) stanowią negatywne czynniki prognostyczne. Wysoki stosunek neutrofilów do limfocytów oraz gorszy stan sprawności stanowią niezależne negatywne czynniki prognostyczne.

The aim was to evaluate inflammatory biomarkers as prognostic factors in patients with triple negativbreast cancer. We have collected data from 143 patients and evaluated using Chi-Squared test, Wilcoxon–Mann–Whitney test and Cox regression. We found a relationship between high neutrophil- to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune inflammation index and local advancement features: tumor (T3/T4) (P = 0.0001, P = 0.0198, P = 0.0001), positive regional lymph nodes (P = 0.0014, P = 0.0075, P = 0.0206). In the multivariate analysis metastatic disease, worse performance status and high NLR (Hazard ratio: 4.48 [2.05–9.80], P=0.0002; 2.23 [1.24–4.03], P=0.0010; 2.23 [1.24–4.03], P=0.0075) were adverse prognostic factors. High neutrophil-to-lymphocyte ratio with worse performance status turned out an adverse independent prognostic factors.
