There are scores of myths surrounding the things we eat: chocolate is almost addictive; Coca-Cola is just a concoction of chemicals; garlic wards off heart disease and cancer; an aspirin a day keeps the doctor away. None of these statements is true, but they contain a germ of truth. In this gallery we can inspect the portraits of some of the natural and unnatural chemicals which a normal diet contains. The pleasures of eating are sweet but fleeting, while the warnings about food seem bitter and never-ending. The warnings we should heed are those of professional dietitians, the front-line troops who are fighting the war against poor nutrition and unbalanced diets. While they help the people who are referred to them, the rest of us only hear their advice second-hand, and even then we do not heed it—which may explain why one person in five is now classed as obese (33% or more overweight) i. the USA, and one in ten in Britain. Behind the front-line dietitians is a regiment of armchair food commanders who offer their advice to anyone who listens. Often it is soundly based, telling us how to lose weight and still be properly nourished, but a lot is rather unhelpful, merely condemning some popular foods as ‘junk’ without explaining why they are so (although this term is generally taken to mean that they contain too much sugar, salt, saturated fats and additives). Examples of junk food are chocolate, colas, hamburgers and french fries. Sadly the healthy alternatives, such as raw celery, mineral water and lentils, lack appeal for many, and especially for children. Alongside claims about junk food come more dire warnings about the chemicals that are present in other foods, and especially if these have been added merely to make food look and taste more tempting, or if they are there as contaminants that come from pesticides and processing. Surprisingly, most food-related illness comes not from these, but from micro-organisms such as bacteria and fungi, and we are most at risk when we eat food that has not been properly stored or prepared. Ideally food should be free of all dangerous impurities, be they bacteria, fungi or chemicals.

The article reveals the essence and specificity of culture as an important component of the spiritual factor of victory. Special attention is paid to the characteristics of fiction. The article substantiates the moral and aesthetic impact on the consciousness of defenders of the Motherland, such works of art as“They fought for the Motherland”,“Leningrad poem”,“Russian character”,“Invasion”, etc. The article describes the significant role of theatrical art, which reveals the moral values of the people and Soviet soldiers. This is reflected in such plays as: “the Front”; “the Guy from our city”; “Once upon a time”, etc. The article substantiates the important role of the spiritual influence of cinema on Soviet people. This influence was realized through artistic images of selfless service to the Motherland, loyalty to military duty. Among these films: “Two fighters”, “Wait for me”, “Front-line friends”. During the war, as the article emphasizes, an important component of the spiritual factor of victory was the musical art. Activities in this area of culture famous musicians:B. Astafiev, S. Prokofiev, D. Shostakovich, A. Alexandrov, V. Soloviev-Sedoy, and others, was implemented in operas, symphonies, cantatas and songs, which by their nature emotional expression differed Patriotic and epic strength. The purpose of the research : to reveal the axiological components, culture of the Russian world, as important components, spiritual factor during the great Patriotic war. Conclusions : the culture of the Russian world at various stages of the great Patriotic War, through a variety of means and forms, actively mobilized all Soviet people to defend the Motherland and defeat Nazi Germany. The spiritual culture of our country and its types, in the course of functioning, during the war, clearly and expressively revealed the idea of patriotism, courage, bravery and heroism, and encouraged the Soviet people, the soldiers of the red Army, to achieve a great Victory.

COVID-19 is a serious coronavirus disease that is spreading all over the world. As of the date of this publication, 2.834.134 people have been infected with COVID-19 and 197.924 deaths have been recorded in 185 countries (John Hopkins Corona Resource Center, 25th April 2020) [1]. This overwhelming mortality rate requires intensive research activities around the world. To date, the number of deaths per day in the United States is still killing, indicating an uncontrollable state of infection spread. SARS-CoV-2 binds to the angiotensin II receptor in various tissues of the human body, particularly in the oral cavity and tongue. SARS-CoV-2 requires the cheerful TMPRSS2 to activate this inertia. SARS-CoV-2 uses the ACE2 receptor as a gateway to the lungs. The SARS-CoV-2 virus binds with the spike protein to the ACE2 receptor. COVID-19 is more common among African Americans in the USA (Science 10th April 2020). The comfort and the emotional loading capacity of the employees in the health service are key components for the maintenance of the essential health services during the outbreak of the COVID-19 virus (Coronavirus) [2,3]. Hence, it will be important to anticipate the charges linked with this work and to release support for employees in the health service. The supervision and assessment of the psychic health and the well-being of the employees in the health service will be important, just as the efforts to guarantee a successful reunion with colleagues if they are infected.

More than 80% of the people in the USA and Canada live in cities. Urban development replaces natural environments with built environments resulting in limited access to outdoor environments which are critical to human health and well-being. In addition, many urban open spaces are unused because of poor design. This paper describes case studies where traditional landscape architectural design approaches would have compromised design success, while evidence-based landscape architecture (EBLA) resulted in a successful product. Examples range from school-yard design that provides safe levels of solar radiation for children, to neighborhood parks and sidewalks that encourage people to walk and enjoy nearby nature. Common characteristics for integrating EBLA into private, public, and academic landscape architecture practice are outlined along with a discussion of some of the opportunities and barriers to implementation.

Traumatic injury is the leading cause of death in young people in the USA. Our knowledge of prehospital resuscitation is constantly evolving and is often informed by research based on military experience. A move toward balanced blood product resuscitation and away from excessive crystalloid use has led to improvements in outcomes for trauma patients. This has been facilitated by new technologies allowing more front-line use of blood products as well as use of tranexamic acid in the prehospital setting. In this article, we review current practices in prehospital resuscitation and the studies that have informed these practices.

In our current endeavor, 3-dimensional (3D) tungsten oxide (WO3) nanostructures (nanocubes, nanobars and nanobricks) have been swiftly generated via hydrothermal route at 160 °C for 24 h. Physico-chemical characterization of the resultant powder revealed formation of WO3 nanostructures with predominantly faceted cube, brick and rectangular bar-like morphology. The present study was also aimed at exploring the antimicrobial and anticancer potential of WO3 nanostructures. Antimicrobial activity was tested against different micro-organisms viz., Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli and Aspergillus fumigatus. The antibacterial and antifungal activity was ascertained against these micro-organisms by measuring the diameter of inhibition zone in agar well diffusion test which revealed that the resultant WO3 nanostructures acted as excellent antibacterial agents against both bacteria and fungi but were more effective against the fungus, A. fumigatus. To examine the growth curves of bacterial cells, time kill assay was monitored for E. coli, against which significant antibacterial action of WO3 nanostructures was noted. The anti-cancer activity of WO3 nanostructures was found to be concentration-dependent against KB cell line by viable cell count method. In our pilot study, WO3 nanostructures suspension with concentration in the range of 10−1 to 10−5 mg/ml was found to kill KB cells effectively.

Abstract Funding Acknowledgements Type of funding sources: Private company. Main funding source(s): Sanofi Introduction The 2020 European Society of Cardiology and the 2019 USA (AHA/ACC/HRS) guidelines recommend the use of AADs for rhythm control in patients with symptomatic AF. This study sought to understand AAD treatment practices and adherence to guidelines across the EU and the USA. Method An online physician survey of cardiologists, cardiac electrophysiologists and interventional electrophysiologists (N = 569) was conducted in the USA, Germany, Italy and the UK. All respondents were actively treating ≥10 AF patients who received drug therapy and/or who had received or were referred for ablation. This extensively detailed survey explored questions on physician demographics, AF types, and drug treatment and ablation practices. Results: Of the responses obtained (1) Amiodarone was used frequently across co-morbidity categories (highest use in those with heart failure with reduced left ventricular ejection fraction [LVEF] [80%]), including in those in which it is not indicated for initial therapy (minimal or no structural heart disease: 26%). Other deviations from guideline recommendations, include: class 1C drugs were used with structural heart disease, including coronary artery disease (CAD) (average class 1C use in CAD-related comorbidities: 6%); sotalol was used with renal dysfunction (22%); and drugs such as sotalol and dofetilide were initiated out of hospital (56% and 17% of respondents, respectively). (2) Nonetheless, a majority of respondents (53%) considered guidelines as the most important non-patient factor in influencing their choice of AF management. (3) Rhythm control was selected more frequently as primary therapy for paroxysmal AF (PAF) (59% of patients) while rate control was used more often for persistent AF (53%). (4) For PAF, AADs were preferred as 1st line more often than ablation, especially if PAF was infrequent and mildly symptomatic (59% of respondents) while ablation was preferred more if frequent symptomatic PAF and for recurrent persistent AF. (5) Rhythm control (AAD or ablation) was chosen in notable numbers for asymptomatic AF and subclinical AF (AADs: 36% and 37%, respectively; ablation: 9% and 14%, respectively). (6) AAD use for those with a first or recurrent episodes of symptomatic AF was 60% or 47%, respectively. (7) Efficacy and safety were chosen as the most important considerations for choice of specific rhythm control therapy (49% and 33%, respectively), and reduction of mortality and cardiovascular hospitalisation (23%) were as important as maintaining sinus rhythm (26%) for rhythm therapy goals. Conclusions Although surveyed clinicians consider guidelines important, deviations in patient types and treatments chosen that compromise safety or were not indicated were common. Findings suggest a lack of understanding of the pharmacology and safe use of AADs, highlighting an important need for further education. Abstract Figure.

In 2019 comes the 70th anniversary of the founding of LLKS – the Union of Lithuanian Freedom Fighters (Lietuvos Laisvės Kovos Sąjūdi). This underground organization had been founded in February of 1949. It united the people, who had been fighting against the Soviet power in Lithuania. Heads of the LLKS were active partisans and they called themselves freedom fighters. In the same time, other people called partisans ‘forest men’, ‘greens’ etc. The main purpose of this article – to consider the process of unification of the forces of Lithuanian partisans under unified command and to highlight the main circumstances of this process. The article is based on the archival materials and modern research writings. So far, very few research papers about Lithuanian anti-Soviet struggle have been published outside Lithuania. That’s why one of the goals of the author – to provide the information about this episode of the modern history of Lithuania to Ukrainian readers. Perhaps, the similarity with Ukrainian national insurgent movement during the 2nd World War will be found. The final ambition of the armed struggle of Lithuanian partisans was the creation of free democratic Lithuania. Partisans considered the mistakes of Lithuanian state-building during the interwar period, such as authoritarian regime and weak social politics. Freedom fighters hoped to get help from the West countries – Great Britain of the USA – through the mediation of Lithuanian emigrants. The unification of partisans was difficult because of the activity of infiltrated Soviet security agents. The chronological framework of the article covers the period of 1946-1949, when where held the main events of the unification of partisans. Active partisan struggle against the Soviet in Lithuania power lasted to 1953.

The concept of “ecological tourism” both in the world and in Russia has appeared in the second half of the twentieth century, although people traveled with natural-focused purposes, including around the protected areas, much earlier. The article presents several definitions of ecotourism, including the two given by the authors. The authors note that ecotourism can be developed in two ways: as a journey on any remaining natural areas or as tour, excursion exclusively within specially protected natural areas (SPNA). The second option is successfully developed in many Englishspeaking countries. The article confirms this fact using the original modern data on the dynamics of visits to the most famous national parks in the USA. Based on the analysis of literature and Internet sources it is concluded that the governance of the Russian Federation considers it necessary to develop eco-tourism in our country according to the second “North American” concept. In this case, the people attending the state protected areas – national parks and reserves with educational and recreational goals should be considered as eco-tourists. Based on this assumption the authors of the article give modern official data concerning the number of specially protected areas of different types in Russia as main destinations of ecotourism. The article presents the diagrams showing the quantitative characteristics of the infrastructure for ecotourists in specially protected areas: visitor centers, museums, ecological paths and routes. The dynamics of tourist arrivals in the reserves and national parks of Russia for the period 2001-2016 years is analyzed. In the final part of the article the main problems of eco-tourists recording are identified.
