Abstract

Background: The histology of the lung includes a variety of cell types. Fibrosis is a universal process, occurring in the skin, intestine, heart, muscles, kidney, blood vessels, liver, and also the lungs. Telocytes are a type of cells with a wide range of properties, which were previously described in healthy and disease-affected organs of human and animal organisms.

Aim: This study aimed to identify telocytes in the lungs of rats and discuss their possible role in the development of pulmonary fibrosis.

Methods: Tissue samples were taken from a group of ten male Wistar rats. Further histological and immunohistochemical analysis was performed. Double immunolabeling for c-kit, vimentin, CD34, and PDGFRα has revealed telocytes in the lungs.

Results: In all tissue samples, telocytes have been identified (in the area of interalveolar septa, close to blood vessels, and between the airway epithelium).

Conclusion: Telocytes might be directly and indirectly (through contact with stem cells, secretomes, and reduction in number) involved in the development of pulmonary fibrosis. The heterogeneity of the telocyte population in different pathologies and their subtypes, as well as their tendency to be common stress their important role in pathological physiology.

Abstract

The aim of the study was to determine the influence of posttraumatic enophthalmos in orbital blow-out fracture on the treatment results. The relationship between time from injury to treatment, type of surgical reconstruction, bone graft site, type of diplopia and treatment results were evaluated. The relationship between the location of the fracture and the degree of enophthalmos was also analyzed. The study included 730 patients, 128 women and 602 men, aged 4 to 77 years, average 28 years, treated because of orbital blow-out fracture in our Department between 1975 and 2015. The study included only patients with an isolated orbital floor or medial wall fracture, so-called „pure blow-out” or „internal blowout”. Fractures of the lower rim, roof or lateral wall of the orbit, as well as the coexistence of other fractures of the facial part of the skull, were excluding citeria from the study. Complete recovery in surgically treated patients was achieved in 405 (58.8%) patients, improvement in 179 (26%) and no improvement in 105 (15.2%) patients. The degree of post-traumatic enophthalmos affects the result of the treatment. The location of the orbital fracture affects the enophthalmos, in our group of patients the largest incidence occurred in the fracture located in the orbital floor combined with medial wall. Patients who underwent surgical treatment up to 14 days after the injury achieved better results than those postponed.

Abstract

The article discusses the operation of solid oxide electrochemical cells (SOC) developed in the Institute of Power Engineering as prospective key components of power-to-gas systems. The fundamentals of the solid oxide cells operated as fuel cells (SOFC – solid oxide fuel cells) and electrolysers (SOEC – solid oxide fuel cells) are given. The experimental technique used for electrochemical characterization of cells is presented. The results obtained for planar cell with anodic support are given and discussed. Based on the results, the applicability of the cells in power-to-gas systems (P2G) is evaluated.

Abstract

This text focuses on non-military aspects of Polish-Soviet relations in cinema before 1989. It offers an analysis of two melodramas, the Polish “Interrupted Flight (L. Buczkowski, 1964),” and the Soviet-Polish “Remember Your Name” (S. Kolosov, 1974). From a narrow ideological perspective, both fi lms show Polish-Soviet relations in a positive light. Yet, the author points to omissions and understatements that refl ect the ambiguities present in Polish-Soviet relations of the time. As a genre. melodrama complicates superfi cial statements of Polish-Soviet friendship.
