    In the report of the World Health Organization from 1990 to 2016 to this day, Ukraine continues to occupy first place in the European region in morbidity and mortality from diseases of the cardiovascular system. One of the predictors and key links in the development of CVD is endothelial dysfunction. In this work, it was shown that chronic loading with sodium nitrite provokes the development of oxidative stress (an increase in 2,3-bisphosphoglyceric acid), inflammation (an increase in the level of interleukin-1-beta, which, in turn, causes a sharp increase in iNOS activity), the development of endothelial dysfunction (increase in von Willebrand factor). L-arginine alone, and in conjunction with the drug β€œVin-Vita” cause a decrease in the negative effect of sodium nitrite

The most likely mechanism that is damaged in the endothelium during peritonitis is the activation of the synthesis of inducible NO-synthase by neutrophils/macrophages in response to infection. It is possible that hyperproduction of nitric oxide (NO), on the one hand, is aimed at destroying microflora and oxidizing toxins, and on the other hand, at suppressing the expression of tissue factor and cell adhesion molecules. platelet aggregation and cascade disorders in the hemostasis system. All this indicates that the hyperproduction of NO not only reflects the processes that occur in the focus of damage to the vascular endothelium, but also affects the severity of the inflammatory process and the outcome of the disease. In animals with experimental peritonitis on the background of OS, an increase in the number of circulating desquamated endothelial cells in the blood, which is a highly specific marker of endothelial dysfunction, was noted. The level of the Willebrand factor also increased, which can serve as a marker of increased risk of thrombus formation and indicate the pathogenetic dependence of the factors that damage the vascular wall endothelium on the concentration of the Willebrand factor, which contributes to the reduction of vascular permeability by adhesion of platelets to the endothelium. Confirmation of the development of endothelial dysfunction in peritonitis is an increase in the concentration of endothelin-1, which is a regulator of the process of vascular neoangiogenesis in response to endothelial damage. Keywords: peritonitis; endothelial dysfunction; oxidative stress; Willebrand factor; pathogenesis

    Background. In industrial heating processes, scaling is a major problem especially when natural water is used as heat carrier. The world economic losses due to scaling are estimated to constitute billions of dollars per year, the development of efficient, environmentally friendly and cheap approaches for reduction of scaling is an actual task nowadays. Utilization of agro-food wastes as a renewable source of scale inhibitors for water treatment of cooling water systems is a promising alternative to the existing approaches. Objective. Three industry by-products, namely rapeseed pomace, sugar beet pulp and fodder radish cake, have been tested as scale inhibitors of mild steel in tap water. Methods. Ethanol extracts were prepared by maceration and the electrochemical approach to study the scale formation was utilized, based on the measurement of oxygen reduction current during nucleation and formation of calcium carbonate in the presence of extracts. Scaling time, porosity and area density of the scale was determined and used to characterize the inhibition efficiency. Chemical compositions of extracts were analysed by GC-MS analysis (gas chromatography with mass selective detector by mass selective integration). Results. The rapeseed pomace extract and fodder radish cake extract at the concentration of 10 mL/L appeared to be efficient scaling inhibitors. Sugar beet pulp extract increases the crystallization time, however the amount of deposited scale appeared to be the same as in the tap water. Conclusions. The scale inhibition is caused mainly by the formation of adsorbed film on the scale nucleus that blocks the surface and prevent further crystal growth. Natural extracts are a promising source of scale inhibitors due to their low price, efficiency and environmental safety.ΠŸΡ€ΠΎΠ±Π»Π΅ΠΌΠ°Ρ‚ΠΈΠΊΠ°.

    Antitrust Damages Actions in Ukraine: Current Situation and Perspectives

    No full text
    The article gives an overview of Ukrainian legislation and experiences concerning antitrust damages actions. The analysis has led to a number of conclusions: private claims are rare in Ukraine due to difficulties in obtaining evidence, high legal costs, and lacking confidence in the Ukrainian court system. The paper gives examples of Ukrainian private antitrust enforcement practice and provides a statistical analysis of the dynamics of β€˜compensated’ damages caused by antitrust infringements in Ukraine. The value of β€˜compensated’ damages is compared to the value of the economic effect of stopping antitrust infringements, as well as to the value of the overall welfare loss deriving from market power in the national economy. Finally, some new sources of damages caused by market power are discussed considering the development perspectives of this branch of antitrust activity

    During the last decade interferons are regarded as potent candidates for generation of plant-based edible vaccines because of broad spectrum of antiviral activities and adjuvant properties. Establishment and certification of numerous interferon producing plant systems requests development of fast and efficient multiplex PCR protocol for the transgene detection in GM plants. Here we represent a protocol for simultaneous amplification in one assay of fragments of hIFN alpha 2b gene and two control genes, namely virD1 of Agrobacterium tumefaciens and conservative region of plant actin gene.Π’ послСднСС дСсятилСтиС ΠΈΠ½Ρ‚Π΅Ρ€Ρ„Π΅Ρ€ΠΎΠ½Ρ‹ Ρ€Π°ΡΡΠΌΠ°Ρ‚Ρ€ΠΈΠ²Π°ΡŽΡ‚ΡΡ ΠΊΠ°ΠΊ пСрспСктивныС ΠΊΠ°Π½Π΄ΠΈΠ΄Π°Ρ‚Ρ‹ для получСния ΠΈΠ· растСний Π² Π²ΠΈΠ΄Π΅ ΡΡŠΠ΅Π΄ΠΎΠ±Π½Ρ‹Ρ… Π²Π°ΠΊΡ†ΠΈΠ½, ΠΏΠΎΡΠΊΠΎΠ»ΡŒΠΊΡƒ ΠΎΠ±Π»Π°Π΄Π°ΡŽΡ‚ ΡˆΠΈΡ€ΠΎΠΊΠΈΠΌ спСктром антивирусной активности ΠΈ Π°Π΄ΡŠΡŽΠ²Π°Π½Ρ‚Π½Ρ‹ΠΌΠΈ свойствами.
