Authors: Tsugorka Oleksandr 
Published: November 2022

The purpose of the research is to find out the role of scenery in theatrical productions, their types and features of their creation by a production designer. The research methodology is based on the complex use of methods of modern art history, which are aimed at the theoretical and artistic-practical understanding of scenery in theatrical productions; the method of art-historical analysis is used, which makes it possible to investigate the trends of the cultural development of theatre technologies; empirical material is studied in a combination of art studies, theatre studies, cultural studies, and historical approaches; the method of formal and stylistic analysis allows revealing the artistic features of scenographic solutions. The scientific novelty lies in the fact that the article is one of the first analytical works in which the author tries to reveal the multifaceted role of scenery in theatrical productions by analysing the definitions of "scenery”, “theatrical and decorative art”, “scenography” that describe the artistic design of theatrical productions. Conclusions. In the process of analysing the role of scenery in theatrical productions, a completely objective impression was formed that scenery is a type of fine art related to the artistic design of a theatrical performance, the elements of which were rooted in antiquity and with minor changes have reached our days and consist of decorations, noise design, lighting, and props, actors' costumes and make-up. Each element has its own function in achieving theatrical expressiveness, which as a whole creates a single artistic whole, the purpose of which is to create the illusion of a place for a theatrical performance. Scenery in theatrical productions is created by a production designer according to the director's idea, which are closely related to the theatre itself, its development and general trends in modern art and modern theatre, the arrangement of theatre premises and the stage, lighting techniques, equipment and many other conditions. The analysis of the definitions of “scenery”, “theatrical and decorative art”, “scenography”, which are used to describe the artistic design of the stage and space in different ways in the scientific and artistic literature, makes it possible to conclude that the scenery is an important part of almost any theatrical performance, and many theatre artists are recognised as independent creators.
Key words: scenery; decorative arts; scenography; theatre and decorative arts; theatre artist.

Published: November 2022

The dangling bond on the surface of bulk materials makes it difficult for a physically contacted heterojunction to form an ideal contact. Thus, periodic epitaxial junctions based on Sb2Te3 nanoblades serialized by Te nanowires (Sb2Te3/Te) were fabricated using a one-step hydrothermal epitaxial growth method. X-ray diffraction and electron microscopy reveal that the as-prepared product has a good crystal shape and heterojunction construction, which are beneficial for a fast photoresponse due to the efficient separation of photogenerated carriers. When the Sb2Te3/Te composite is denoted as a photodetector, it shows superior light response performance. Electrical analysis showed that the photocurrent of the as-fabricated device declined with temperatures rising from 10K to 300K at 980 nm. The responsivity and detectivity were 9.5 × 1011 μA W−1 and 1.22 × 1011 Jones at 50 K, respectively, which shows better detection performance than those of other Te-based photodetector devices. Results suggest that the as-constructed near-infrared photodetector may exhibit prospective application in low-temperature photodetector devices.

IntroductionPseudomonas aeruginosa is a common clinical opportunistic pathogen. Antibiotic resistance of P. aeruginosa is frequent, and it affects the clinical curative effect and leads to recurrent infections, disease progression, and difficult treatment, especially in cystic fibrosis patients. The drug-resistance mechanism of P. aeruginosa is complex, and biofilms play an important role. Given the widespread antibiotic resistance of P. aeruginosa, the discovery of a drug that can prevent or eradicate biofilm formation is imperative. Daphnetin (DAP), a coumarin derivative, is a safe, non-toxic, natural compound with antibacterial and anti-biofilm properties. Herein, this study highlights the bacterial motility effects, antibacterial effect, pyocyanin production, and anti-biofilm potential of DAP against P. aeruginosa.MethodsIn this study, the minimal inhibitory concentration of DAP against P. aeruginosa was determined using the microdilution method. The antibiofilm activity of DAP against P. aeruginosa was determined using crystal violet staining, colony-forming unit enumeration, and scanning electron microscopy. The effect of DAP on P. aeruginosa motility was detected using the swimming, swarming, and twitching agar plates to measure the diameter of the concentric area.ResultsWe found that DAP at concentrations of 0.445–1.781 mg/mL and 0.89–1.781 mg/mL can effectively inhibit biofilm formation and eradicate the formed biofilm of P. aeruginosa, respectively. DAP reduced pyocyanin production and inhibited bacterial motility of P. aeruginosa.DiscussionIn conclusion, our results support the conclusion that DAP can effectively eradicate formed biofilm and inhibit biofilm formation, bacterial motility, and pyocyanin production of P. aeruginosa and may represent a natural anti-biofilm therapeutic agent.

Published: November 2022

IntroductionThis study aimed to identify whether interleukin-6 (IL-6) is better than C-reactive protein (CRP) for the prediction of severe acute pancreatitis (SAP), infected pancreatic necrosis (IPN), and mortality.MethodsSixty-seven patients with acute pancreatitis (AP) who were hospitalized within 48 h of onset and received serum CRP and IL-6 tests from September 2018 to September 2019 were included. Spearman’s correlation was performed to assess their associations with severity. The areas under the curve (AUCs) for the prediction of SAP, organ failure, pancreatic necrosis, IPN, and mortality were estimated using receiver operating characteristic curves.ResultSerum CRP and IL-6 levels were significantly positively correlated with the severity of AP (p &lt; 0.05). The AUC for the prediction of SAP based on the CRP level was 0.78 (95% CI, 0.66–0.89) and that based on the IL-6 level was 0.69 (95% CI, 0.56–0.82). For the prediction of organ failure and pancreatic necrosis, CRP was more accurate than IL-6 (AUC 0.80 vs. 0.72 and 0.75 vs. 0.68, respectively). However, CRP was less accurate than IL-6 for predicting mortality and IPN (AUC 0.70 vs. 0.75 and 0.65 vs. 0.81, respectively). Systemic inflammatory response syndrome plus CRP was more accurate than systemic inflammatory response syndrome plus IL-6 (AUC 0.79 vs. 0.72) for the prediction of SAP.ConclusionsIL-6 was more accurate than CRP for predicting mortality and IPN in patients with AP.

Published: November 2022

BackgroundCoronary microvascular dysfunction (CMD) may play an important role in various cardiovascular diseases, including HFpEF and both obstructive and non-obstructive coronary artery disease (CAD). To date, there has been no bibliometric analysis to summarize this field. Here, we aim to conduct a bibliometric analysis of CMD to determine the current status and frontiers in this field.Materials and methodsPublications about CMD were taken from the Web of Science Core Collection database (WOSCC). WOSCC’s literature analysis wire, the VOSviewer 1.6.16, and CiteSpace 5.1.3 were used to conduct the analysis.ResultsA total of 785 publications containing 206 reviews and 579 articles are included in the sample. The leading authors are Iacopo Olivotto, Paolo G. Camici, and Carl J. Pepine. The most productive institutions are the University of Florence, Cedars Sinai Medical Center, and Harvard University. The most productive countries are the USA, Italy, and England. There are a total of 237 journals that contribute to this field, and the leading journals in our study were the International Journal of Cardiology, the European Heart Journal and the JACC. From 2012 to 2021, the top three most-cited articles focused on the association between HFpEF and CMD. The important keywords are heart failure, hypertrophic cardiomyopathy, chest pain, women, coronary flow reserve (CFR), endothelial dysfunction and prognostic value. “Positron emission tomography” shows the strongest burst strength, followed by “blow flow” and “artery.” The keywords that started to burst from 2015 are particularly emphasized, including “heart failure,” “coronary flow reserve,” and “management.”ConclusionStudies about CMD are relatively limited, and the largest contribution comes from the USA, Italy and England. More studies are needed, and publications from other countries should be enhanced. The main research hotspots in the CMD field include CMD in patients with HFpEF, sex differences, the new methods of diagnosis for CMD, and the effective treatment of CMD. Attention should be given to CMD in patients with HFpEF, and untangling the association between CMD and HFpEF could be helpful in the development of physiology-stratified treatment for patients with CMD and HFpEF.
