Excimer laser coronary atherectomy (ELCA) is a long-established adjunctive therapy that can be applied during percutaneous coronary intervention (PCI). Technical aspects have evolved and there is an established safety and efficacy record across a number of clinical indications in contemporary interventional practice where complex lesions are routinely encountered. The role of ELCA during PCI for thrombus, non-crossable or non-expandable lesions, chronic occlusions and stent under-expansion are discussed in this review. The key advantage of ELCA over alternative atherectomy interventions is delivery on a standard 0.014-inch guidewire. Additionally, the technique can be mastered by any operator after a short period of training. The major limitation is presence of heavy calcification although when rotational atherectomy (RA) is required but cannot be applied due to inability to deliver the dedicated RotaWire™ (Boston Scientific), ELCA can create an upstream channel to permit RotaWire passage and complete the case with RA – the RASER technique.

Campo de Dalías, located in southeastern Spain, is the greatest European exponent of greenhouse agriculture. The development of this type of agriculture has led to an exponential economic development of one of the poorest areas of Spain, in a short period of time. Simultaneously, it has brought about a serious alteration of natural resources. This article will study the temporal evolution of changes in land use, and the exploitation of groundwater. Likewise, this study will delve into the technological development in greenhouses (irrigation techniques, new water resources, greenhouse structures or improvement in cultivation techniques) seeking a sustainable intensification of agriculture under plastic. This sustainable intensification also implies the conservation of existing natural areas.

Background. Vitamin C, E, D, A, zinc are considered to be essential in preventing and treating of acute respiratory infections (ARI) including COVID-19. Methods. We reviewed published studies evaluating the potential roles of these vitamin and zinc for ARIs and COVID-19 using Medline database, medRxiv, and bibliographic references. Results. Vitamins C, D, and E did not reduce incidence of common cold in general, but vitamin C reduced by half in population with physical and environment stresses. Vitamins C and E shortened duration and reduced severity of common cold. A large-dose vitamin A had no effect on recovery from pneumonia. Zinc improved clinical deterioration and pneumonia duration in under five. The effect on preventing COVID-19 morbidity and related-death was lacking. Conclusions. Although the effects of vitamins and zinc on ARIs including COVID-19 were inconclusive, taking these for a short period during pandemic may be beneficial when there is risks of deficiency.

The paper analyzes the course of events and the international context of Сarpatho- Ukrainian state’s rise and defeat in terms of role and impact of the leading European actors at the end of the 1930’s. Based on an in-depth study of the wide range of literature, documents and relevant archives, the author highlights the role of Carpatho-Ukraine, which for a short period happened to be at the epicenter of the geopolitical interests of the states whose actions or inaction fueled the warmongers. The revival and strengthening of a number of European countries at that historical period deteriorized international relations. The erosion of the Versailles-Washington bases intensified the contradictions in the foreign policy between the victorious and vanquished states. The defeated countries reinforced their positions, since the victors, who were expanding their military might at the expense of Czechoslovak Republic, including Transcarpathia, were becoming more submissive in accommodating territorial claims. This situation largely updated the approaches to the Ukrainian question. The variability of the ways to solve it largely depended on the situational decisions of the Third Reich political leadership.

В статье на основе методов включенного наблюдения и интервьюирования современников, материалов периодической печати представлена картина проведения 9 мая на территориях Донецкой народной республики и Луганской народной республики. В ходе исследования удалось выяснить, что в республиках эта дата вышла за рамки памяти о событиях и участниках Великой Отечественной войны, дополнившись новыми смыслами, приобретя свои особенности и знаковость. Коммеморативные практики не ограничились только погибшими в период Великой Отечественной войны: они включили в себя и погибших военных в действующем вооруженном конфликте на Донбассе, и погибших мирных граждан республик. Особое внимание уделяется роли Русской православной церкви Московского патриархата (РПЦ МП) в мероприятиях, проводимых по случаю праздника. Праздничная атрибутика включает в себя ряд уникальных символов и знаков, характерных только для Дня Победы. Вместе с тем 9 мая на темпоральном отрезке занимает небольшой часовой промежуток времени, а потенциал эмоциональной составляющей и наполненность дня больше сравнима с праздничной культурной традицией, чем с коммеморативной. This article describes Victory Day commemorations (9 May) in the territories of the Donetsk People’s Republic and the Lugansk People’s Republic, based on observation, interviews, and material from the periodical press. In the course of the study, it was found out that in the republics celebration of this date went beyond the memory of the events and participants of the Great Patriotic War. The holiday assumed new meanings, acquiring its own characteristics and markers. Commemorative practices were not limited to participants of the Great Patriotic War, but were also devoted to the military and civilian dead in the current armed conflict in the Donbas. Particular attention is paid to the role of the Russian Orthodox Church of the Moscow Patriarchate (ROC MP) in events held on this day. The holiday’s celebration includes a number of unique symbols and signs that are only characteristic of the 9th of May. While the celebration of 9 th of May takes but a short period of time, its emotional component and capacity for expression are more comparable to the festival tradition than to that of commemoration. At the same time, on the temporal segment, 9th of May takes a short one-hour period of time, and the potential of the emotional component and the fullness of the day is more comparable to the festive cultural tradition than to the commemorative one.

Based on the analysis of the previously unused archival sources and research works on the history of Russian cooperation, the main areas of the activities of the Akmola District Union of Cooperatives in 1917–1922 are studied and generalized. In terms of methodology, the study is based on the works of ideologists of Russian cooperation (M.I. Tugan-Baranovsky, V.F. Totomianets, A.V. Chayanov, and others) and the original concepts they developed. The article analyzes the activities of the Union of Cooperatives of a particular micro-region: the number of employees, organizational structure and management, organization of industrial production, financial and social policies, cultural and educational activities. The author substantiates the role of the District Union of Cooperatives in the development of economic relations in the region and in the district peasant farms’ entry into the all-Russian market. Despite the difficult political circumstances and the relatively short period of existence (from August 1917 to the end of 1922), the Akmola District Union of Cooperatives became an economic and organizational center, contributed to the establishment and development of the consumer cooperation system not only in the district, but also in the region: it initiated the establishment of the regional Union of Steppe Cooperatives. In the conditions of the territorial remoteness from industrial centers and the underdeveloped transport infrastructure, the District Union of Cooperatives significantly facilitated and promoted the production activities of the peasants of the region connecting them with the market, expedited the involvement of Kazakh farms in the regional economy. The Union carried out an active social policy and diversified cultural and educational work, allocated significant amounts from its profits to the development of education in the district. According to the author, the activities of the Akmola District Union of Cooperatives can be considered as an integral part of the national cooperative movement, and its success was due to the application of the allRussian experience during the heyday of cooperation in the country.

AbstractThe recent outbreak by SARS-CoV-2 has generated a chaos in global health and economy and claimed/infected a large number of lives. Closely resembling with SARS CoV, the present strain has manifested exceptionally higher degree of spreadability, virulence and stability possibly due to some unidentified mutations. The viral spike glycoprotein is very likely to interact with host Angiotensin-Converting Enzyme 2 (ACE2) and transmits its genetic materials and hijacks host machinery with extreme fidelity for self propagation. Few attempts have been made to develop a suitable vaccine or ACE2 blocker or virus-receptor inhibitor within this short period of time. Here, attempt was taken to develop some therapeutic and vaccination strategies with a comparison of spike glycoproteins among SARS-CoV, MERS-CoV and the SARS-CoV-2. We verified their structure quality (SWISS-MODEL, Phyre2, Pymol) topology (ProFunc), motifs (MEME Suite, GLAM2Scan), gene ontology based conserved domain (InterPro database) and screened several epitopes (SVMTrip) of SARS CoV-2 based on their energetics, IC50 and antigenicity with regard to their possible glycosylation and MHC/paratopic binding (Vaxigen v2.0, HawkDock, ZDOCK Server) effects. We screened here few pairs of spike protein epitopic regions and selected their energetic, IC50, MHC II reactivity and found some of those to be very good target for vaccination. A possible role of glycosylation on epitopic region showed profound effects on epitopic recognition. The present work might be helpful for the urgent development of a suitable vaccination regimen against SARS CoV-2.

<p>Ocean acidification is a consequence of current anthropogenic climate changes. The concomitant decrease in pH and carbonate ion concentration in sea water may have severe impacts on calcifying organisms. Coral reefs are among the first ecosystems recognized vulnerable to ocean acidification. Within coral reefs, large benthic foraminifera (LBF) are major calcium carbonate producers.</p><p>The aim of this study was to evaluate the effects of varying pH on survival and calcification of the symbiont-bearing LBF species <em>Peneroplis</em> spp. We performed culture experiments to study their resistance to ocean acidification conditions, as well as their resilience once placed back under open ocean pH (7.9).</p><p>After three days, small signs of test decalcification were observed on specimens kept at pH 7.4, and severe test decalcification was observed on specimens kept at pH 6.9, with the inner organic lining clearly appearing. After 32 days under pH 7.4, similar strongly decalcified specimens were observed. All the specimens were alive at the end of the experiment. This result demonstrates the resistance of <em>Peneroplis </em>spp. to an acidified pH, at least on a short period of time.</p><p>After being partially decalcified, some of the living specimens were placed back at pH 7.9. After one month, the majority of the specimens showed recalcification features, mostly by addition of new chambers. The trace elements concentrations of the newly formed chambers were analysed by LA-ICPMS. Interestingly, more chambers were added when food was given, which highlights the crucial role of energy source in the recalcification process. Moreover, the newly formed chambers were most of the time abnormal, and the general structure of the tests was altered, with potential impacts on reproduction and in situ survival. In conclusion, if symbiont-bearing LBF show some resistance and resilience to lowered pH conditions, they will remain strongly affected by ocean acidification.</p>
