Opis:
Purpose: The article aims to assess the informative value of the financial statements of public enterprises, auxiliary enterprises and budget institutions which have been transformed into public sector enterprises (IGB). The goal of the article is also to interpret the data included in financial statements, from the property and structure management point of view. Metodology: The main research tool was the economical analysis of the chosen elements of the financial statements of public sector enterprises. Review of the data which describe the public sector enterprises which conduct business activities was done. In relation to “Center of Logistic Services” entity, the method of case study was used. Findings: The analysis shown in the article implies that the legal and organisational changes have not improved the public finance sector operations in this area. It results from the fact that the changes in management, way of thinking should be directed to managerial model. Research implications: The article is the first author’s insight into the problem of public sector enterprises. There is no doubt, this type of research should be continued in many aspects. Originality: The author presented the interesting and current problem concerning public finance sector. Stated in the article theses and the analysis of the financial standing of the public sector enterprises is one of the opinions in the debate on the expected direction of changes in the organisation of public finance sector.

Opis:
Nowadays, the Mechanical Circulatory Support (MCS) within the Ventricular Assist Devices (VAD) appears to be a reliable and effective solution for patients with advanced heart failure (HF). After many years of work, extracorporeal pulsatile VADs have been replaced by new generations of implantable continuous flow (CF) pumps. Clinical experience has shown that present-day pump constructions still need to be improved to minimize the risk of complications during heart assistance. One of the complications is the pump inflow obstruction caused by the ingrowth of tissue into the blood inflow path and pump thrombosis. The main goal is to develop a coating for the external surface of the inflow cannula to provide controlled tissue ingrowth. The smooth surface of the cannula external wall results in the tissue overgrowth into the pump inflow orifice, and may be a source of emboli. The paper presents external surface modifications of the inflow cannula performed by different VAD manufacturers within the topography characterization. The inflow cannulas used in CF VADs are mainly made of titanium alloy due to its mechanical properties and high biocompatibility. In general, the discussed surface coatings were characterized by the roughness of about ≈ Ra = 15 μm, high porosity and good wettability Φ ≈ 60°. The surface was covered with titanium microspheres or titanium mesh. The developed surfaces and clinical experience confirm the ability to control the tissue ingrowth along the external surfaces of the inflow cannula at the tissue-implant interface.

Opis:
The aim of the study was to determine the influence of long term exposure to Ringer’s solution of biodegradable polymer coatings containing an active substance on the Ti6Al7Nb alloy substrate on the physical and chemical properties of the coatings and the degradation process of the metal substrate. The studies used poly(L-lactide-co-trimethylene carbonate) P(L/TMC), poly(L-lactide-co-trimethylene carbonate-glycolide) P(L/TMC/G) and poly(D,L-lactide-glycolide) (PLGA) coatings applied to the anodically oxidized Ti6Al7Nb alloy by means of dipping method (1, 2 and 3 dips). The polymer coatings contained ciprofloxacin. Roughness and wettability tests were carried out on the substrate and polymer coatings, the pitting corrosion resistance of the substrate and samples with polymer coating was determined, the number of metallic ions released to the solution from the coated and uncoated samples was determined as well as the adhesion of polymer coatings. The research was supplemented by microscopic observations. The results of the research indicate different influence of exposure to Ringer’s solution on the physical and chemical properties of biodegradable polymer coatings containing ciprofloxacin and the course of the degradation process of the metal substrate.
