Introduction: The natural anticoagulant—activated protein C system plays an important role in the pathogenesis of idiopathic pulmonary fibrosis. The purpose of this study was to evaluate the concentration of protein C (PC), protein S (PS), thrombomodulin (TM), selectin E (sSelE), and thrombin–antithrombin complex (TAT) in patients with idiopathic pulmonary fibrosis (IPF). Material and methods: Study grup consisted of 11 patients aged 51.5 ± 8.62 years with idiopathic pulmonary fibrosis and 20 healthy adults as control. Concentration of PC, PS TM, sSelE and TAT in plasma with ELISA method was assessed. Results: We observed significantly lower plasma concentration of PC (98.24 ± 16.17% vs. 130.59 ± 19.03%), PS (71.31 ± ± 12.95% vs. 93.47 ± 18.63%), TM (2.67 ± 0.40 ng/ml vs. 3.99 ± 1.16 ng/ml) and significantly higher level of TAT complex (Me = 4.00 mg/ml vs. 2.20 mg/ml) and sSelE (Me = 36.40 ng/ml vs. 22.84 ng/ml) in patients with idiopathic pulmonary fibrosis as compared to controls. Conclusions: In presented pilot study we observed decreased activity of protein C system and increased thrombin generation in peripheral blood of patients with idiopathic pulmonary fibrosis.
The paper presents an assessment of thermal energy consumption for heating in 10 buildings made in the OWT-67N prefabricated large-panel technology from 1983 to 1986. The work covers the years 2002-2020 in three periods: before and after thermal modernization and after the use of an innovative weather prediction heating system control in buildings. The analysis made it possible to assess the impact of carrying out a deep thermal modernization, and then installing a modern forecast regulation system in terms of reducing heat energy consumption for central heating purposes, as well as reducing greenhouse gas emissions, such as CO2, SOx, NOx, CO and www.videleaf.com benzo(a)pyrene, into the atmosphere. The implementation of deep thermal modernization in buildings allowed for savings of 19.8-35% of thermal energy consumption for heating. The use of additional regulation based on prediction saved from 4.8 to 23.5%, except for one building BU10, where there was an increase in final energy consumption by 2.1%. Replacing the weather regulation in heating stations with the forecast regulation additionally reduced the emission of pollutants by 11.1%, compared to the reduction of pollutants achieved as a result of the thermal modernization of buildings alone, amounting to an average of 29.7%.
