Snakebite envenoming is a health concern and has been a neglected tropical disease since 2017, according to the World Health Organization. In this study, we evaluated the ability of ten 1,2,3-triazole derivatives AM001 to AM010 to inhibit pertinent in vitro (coagulant, hemolytic, and proteolytic) and in vivo (hemorrhagic, edematogenic, and lethal) activities of Bothrops jararaca venom. The derivatives were synthesized, and had their molecular structures fully characterized by CHN element analysis, Fourier-transform infrared spectroscopy and Nuclear magnetic resonance. The derivatives were incubated with the B. jararaca venom (incubation protocol) or administered before (prevention protocol) or after (treatment protocol) the injection of B. jararaca venom into the animals. Briefly, the derivatives were able to inhibit the main toxic effects triggered by B. jararaca venom, though with varying efficacies, and they were devoid of toxicity through in vivo, in silico or in vitro analyses. However, it seemed that the derivatives AM006 or AM010 inhibited more efficiently hemorrhage or lethality, respectively. The derivatives were nontoxic. Therefore, the 1,2,3-triazole derivatives may be useful as an adjuvant to more efficiently treat the local toxic effects caused by B. jararaca envenoming.
Methylglyoxal and high glucose inhibit VEGFR2 phosphorylation at specific tyrosine residues
Authors: Betting Fabian , Schlunck Günther , Agostini Hansjürgen T. , Martin Gottfried
Published: June 2022

Diabetes is characterized by hyperglycemia and a significant risk of vascular complications. Vascular endothelial growth factor (VEGF) and its main receptor VEGFR2 (KDR), which is highly expressed in vascular endothelial cells, are essential mediators of vascular maintenance and angiogenesis. During glycolysis after high calorie food intake, methylglyoxal (MGO) is formed and MGO blood levels are elevated in diabetes. MGO reacts with arginine residues to generate MG-H1 or with lysine residues to carboxyethyl lysine which are common components of advanced glycation end-products. Therefore, the question arises whether hyperglycemic conditions affect VEGF signaling via a ligand-independent direct modification of signaling components. As a first step, the effect of MGO on VEGFR2 activation was investigated in cultured endothelial cells from human umbilical vein by determination of VEGFR2 phosphorylation at selected tyrosine residues by ELISA and immunoblotting using phospho-specific antibodies. Phosphorylation of VEGFR2-Y996, VEGFR2-Y1054, or VEGFR2-Y1175 reached a maximum 5 min after stimulation of endothelial cells with VEGF. Phosphorylation was significantly inhibited by 100 µM MGO and to a lesser extent by high glucose treatment. 2,3-Pentanedione and glyoxal were investigated for comparison. In summary, VEGFR2 phosphorylation is sensitive to MGO or high glucose concentrations which may be relevant in the pathophysiology of microvascular disease in diabetes.
Considerations to Optimize Strength and Muscle Mass Gains Through Flywheel Resistance Devices: A Narrative Review
Authors: Raya-González Javier , Castillo Daniel , de Keijzer Kevin L. , Beato Marco
Published: June 2022

Flywheel (FW) resistance training is a valid and time-efficient method to improve force production and muscular hypertrophy. However, no definitive consensus exists regarding FW parameters for optimizing chronic training responses. Therefore, this review aims to examine the FW training literature and provide evidence-based conclusions and practical applications for practitioners. This review reports that FW resistance training is a valid strategy to improve force, power, and hypertrophy responses; however, differences with traditional training programs have not been clearly established. It is not possible to state that FW training is superior to traditional resistance training methodologies. Moreover, the differences between populations and sex should be studied in further depth to establish robust conclusions. Finally, this review reports variables (duration, volume, and intensity) that should be adopted to improve force, power, and hypertrophy responses—even though future research is needed to establish the appropriate training dose for specific populations.

Authors: Liu Xiaoning , Jiang Xiao , Zhu Zheng , Sun Liqin , Lu Hongzhou
Published: June 2022

While the COVID-19 pandemic continues, the world is on high alert regarding the second public health threat of a global monkeypox outbreak. Monkeypox, a relative of smallpox, is a zoonotic disease that was initially restricted to Africa. However, a novel outbreak has occurred in Europe, a non-endemic region, starting in May 2022. In the face of this unprecedented event, people should be aware of several crucial facts regarding monkeypox to support global public health prevention and control of the outbreak, including pathogenetic epidemiological and diagnostic aspects. As the cases outside Africa rapidly increase, including in a large proportion of men who have sex with men, thinking about the potential effects on global public health, as well as the shifting epidemiological trends of monkeypox and the insights from this novel outbreak, will be crucial.
Advances in Acute Severe Hepatitis of Unknown Etiology in Children
Authors: Zhou Xuefeng , Lu Hongzhou
Published: June 2022

Since the International Health Regulations National Focal Point for the United Kingdom alerted the WHO of ten cases of acute severe hepatitis of unknown etiology in children on April 5, 2022, relevant cases have been reported worldwide. These patients had acute hepatitis (negative for hepatitis viruses A–E) and elevated aminotransferase (AST) or alanine aminase (ALT) exceeding 500 U/L. Furthermore, severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) and/or adenovirus type F41 have been detected in some cases. This unknown hepatitis has been hypothesized to be induced by a viral reservoir of novel coronavirus superantigen, which repeatedly stimulates the intestines and leads to a multisystem inflammatory syndrome in children (MIS-C), which causes immune abnormalities in the presence of human adenovirus. Although this hypothesis has not been confirmed by any in vivo experimental or clinical studies, it may provide ideas for possible intervention strategies.

Published: June 2022

Kisspeptin system was shown to be a key factor in mediating social stress and reproduction. Yellowtail clownfish, Amphiprion clarkii, is a hermaphrodite fish, whose sex determination and gonadal development are affected by the social status of individuals. The yellowtail clownfish is a fantastic animal model to explore sex determination, but the social status and precise distribution of kiss mRNAs in the brain of this species are unknown. Hererin, a novel in situ hybridization technique, RNAscope, was used to investigate the distribution of kiss1 and kiss2 expressions in the brain of yellowtail clownfish. The coronal planes of brain showed that the kiss1 signal was mainly present in dorsal habenular nucleus (NHd) and kiss2 mRNA was widely expressed in telencephalon, midbrain, and hypothalamus, especially in dorsal part of the nucleus of the lateral recess (NRLd). Additionally, kiss1 and kiss2 signals have sexually dimorphic distribution. The kiss1 mRNA was distributed in NHd, the telencephalon, and lateral part of the diffuse nucleus of the inferior lobe (NDLIl) of females but in NHd and NDLIl of males. kiss2 signals were stronger in females than that in males. The distribution of kiss1 and kiss2 neurons in NHd of habenula and NRLd of hypothalamus may suggest that kiss genes associate environmental signaling and reproductive function in yellowtail clownfish.

Published: June 2022

Purpose

In patients with type 2 diabetes mellitus (T2DM), Roux-en-Y gastric bypass (RYGB) leads to beneficial metabolic adaptations, including enhanced incretin secretion, beta-cell function, and systemic insulin sensitivity. We explored the impact of RYGB on pituitary, pancreatic, gut hormones, and cortisol responses to parenteral and enteral nutrient stimulation in patients with obesity and T2DM with repeated sampling up to 2 years after intervention.

Methods

We performed exploratory post hoc analyses in a previously reported randomized trial. Levels of adrenocorticotropic hormone (ACTH), cortisol, growth hormone (GH), glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), peptide YY (PYY), ACTH, insulin, and glucagon were measured in 13 patients with T2DM and obesity at four different visits: before and 4, 24, and 104 weeks after RYGB; and in three sequential conditions on the same day: fasting, intravenous arginine challenge, and OGTT.

Results

RYGB surprisingly induced a rise in ACTH, cortisol, and GH levels upon an oral glucose load, together with enhanced GLP-1 and PYY responses. Fasting and post-arginine GH levels were higher after RYGB, whereas insulin, glucagon, GLP-1, GIP, and cortisol were lower. These endocrine adaptations were seen as early as 4 weeks after surgery and were maintained for up to 2 years.

Conclusion

These findings indicate adaptations of glucose sensing mechanisms and responses in multiple endocrine organs after RYGB, involving the gut, pancreatic islets, the pituitary gland, the adrenals, and the brain.
Pheochromocytoma and paraganglioma: germline genetics and hereditary syndromes
Authors: Turin Christie G , Crenshaw Molly M , Fishbein Lauren
Published: June 2022

Pheochromocytomas (PCCs) and paragangliomas (PGLs) are neuroendocrine tumors arising from the adrenal medulla and extra-adrenal ganglia, respectively. Approximately 15–25% of PCC/PGL can become metastatic. Up to 30–40% of patients with PCC/PGL have a germline pathogenic variant in a known susceptibility gene for PCC/PGL; therefore, all patients with PCC/PGL should undergo clinical genetic testing. Most of the susceptibility genes are associated with variable penetrance for PCC/PGL and are associated with different syndromes, which include susceptibility for other tumors and conditions. The objective of this review is to provide an overview of the germline susceptibility genes for PCC/PGL, the associated clinical syndromes, and recommended surveillance.
The Nexus between Causal Macroeconomic Relations in Japan
Authors: Zestos George K , Jiang Yixiao , Patnode Ryan
Published: June 2022

Japan achieved phenomenal economic growth after WWII. Starting in the early 1990s, however, the Japanese economy began experiencing a prolonged deflation-stagnation period widely known as the “Lost Decades”. Based on data from the World Bank and the Federal Reserve Bank of Saint Louis, this paper employs an autoregressive distributed lags (ARDL) model to find evidence of a long run relation among the real GDP, real imports, the real exchange rate, and the public debt-to-GDP ratio for Japan. Once cointegration is established with the Bounds Test, Granger Causality tests are performed by employing an estimated Vector Autoregressive (VAR) model with the same variables. The empirical results support Granger causality in all directions. In particular, we found real imports and public debt-to-GDP ratio to directly cause real GDP. Interestingly, the real exchange rate causes real GDP indirectly via imports. The public debt had a negative effect on GDP but did not wreak havoc on the Japanese economy. The study also examines whether former Prime Minister Shinzō Abe’s unprecedented macroeconomic policies and structural reforms launched in 2013, known as Abenomics, are pulling Japan out of its economic doldrums.
Demand for Money in Greece After Euro Area and Policy Uncertainties
Authors: Ongan Serdar , Gocer Ismet
Published: June 2022

This study examines the asymmetric effects of uncertainties in monetary policy on the demand for money in Greece. In doing so, it introduces and uses the monetary policy uncertainty (MPU) index, which can probably be a very appropriate and robust explanatory variable in demand-for-money models. Therefore, this study with this index differs from previous empirical studies that use conventional uncertainty-based independent variables. Empirical findings of both models indicate that changes in the MPU index have significant effects on Greek money demand. Additionally, compendious inferences of the nonlinear model for the Greek people’s financial preferences are as follow as: (i): Greek people invest more in alternative financial instruments and/or spend their money rather than hold (demand) it when the MPU index rises, (ii): Greek people’s money demand in both increases and decreases in the MPU index is predominantly determined by longer-term bond rate changes.

Subject and Purpose. The paper is concerned with the behavior of a nonlinear dynamic system that has two degrees of freedom and whose joint nonlinearity is established by all the nonlinear coupling between the degrees of freedom. The purpose is to find out if the Krylov—Bogolyubov—Mitropolsky (KBM) method is applicable to a system of partial differential equations. Methods and Methodology. The consideration of the problem is by the Krylov—Bogolyubov—Mitropolsky method in the first approximation. Then the results are treated using numerical methods. Results. An electromechanical system with two degrees of freedom and a known parametric resonance has been studied using the Krylov—Bogolyubov—Mitropolsky method in the first approximation. The phase space of the system has been described. It has been shown that the obtained solution covers an energy periodic transfer between the two degrees of freedom. The difference between the considered oscillation system and its analogs discussed in the literature lies in that the considered circuit is parametrically excited by an internal force rather than external one. In a similar system of two circuits connected through a diode, the coupling includes a linear component. In the system of present concern, the coupling is all-nonlinear. Conclusion. The obtained results are of interest for the research into internal nonlinear resonances between degrees of freedom in an oscillation system that has two degrees of freedom and whose joint nonlinearity is due to all the nonlinear coupling between the degrees of freedom. The considered system can serve a test example in the development of programs implementing the Krylov—Bo- golyubov—Mitropolsky method as applied to an oscillation system with numerous degrees of freedom and a small nonlinearity.

Subject and Purpose. In Part 1 of the paper, a mathematical model of an autodyne self-oscillator with frequency tuning by varactor capacitance varying is built and thoroughly analyzed for the features of signal formation in autodyne radar with a wide frequency-modulation bandwidth and a nonlinearity in the modulation characteristic. The aim of the study is to appreciate the action that the nonlinearity of the oscillator modulation characteristic exerts on the spectral characteristics of signals from frequency-modulation autodyne radar. Methods and Methodology. The research method is a mathematical analysis of the operation of an autodyne oscillator with electronic frequency tuning. To examine formation processes of emitted autodyne signals, the spectral, frequency and amplitude characteristics of signals from frequency-modulation autodyne radar are constructed with the use of numerical modeling techniques. Results. Numerical modeling of autodyne response signal spectra has been performed for various distances to the reflecting object and different modulating voltages across the varactor. It has been shown that a nonlinear dependence of the generator frequency on the varactor voltage makes for the broadening of the autodyne response signal spectrum. It has been found that as the object distance increases, the frequency of the autodyne response signal moves towards the higher frequencies, while the nonlinearity makes the spectrum broaden. The obtained calculation results refer to an 8-mm Gunn diode autodyne. Conclusion. The performed research of the spectral characteristics and into the features of signal formation in autodyne transceiver devices with a wide frequency tuning has shown that in order to achieve high resolution figures from autodyne radar, certain methods are needed to be developed for adjusting the laws of frequency modulation and for the processing of response signals from reflecting objects. Such a method and ways to solve these problems will be presented in Part 2 of the work.

У статті обстоюється думка, що сучасна російсько-українська війна є постколоніальною за своєю природою і спричинена імперським синдромом нинішньої Росії. Розглянуто вузлові проблеми підневільного становища України у Російській імперії та СРСР, зокрема складні конфігурації залежності. Акцентовано увагу на адаптації старої імперської спадщини в радянському державно-політичному проєкті. Відзначено своєрідність західної рецепції історії України у світлі постколоніальних студій. Проаналізовано російський дискурс виправдання сучасної війни в контекстах імперської та радянської спадщини. Зазначено, що війна Росії проти України має реваншистський та антиглобалістський характер, оскільки зорієнтована на відновлення залежного становища пострадянського простору та перегляд світоустрою після розпаду СРСР. Наголошено, що для українців війна є екзистенційною, позаяк сучасна Росія де-факто не визнає ані Україну як державу, ані українську ідентичність.

Zoltán Kodály and Hungarian Dance
Authors: Pávai István
Published: June 2022

In addition to folk music, Zoltán Kodály was interested in folk dance. This is evidenced not only by his writings dedicated to the subject – some relevant ideas are to be found in his publications mainly focused on other topics. In this article, the author collects both Kodály's writings explicitly related to folk dance as well as the “hidden” ideas, presented partly chronologically, partly in thematic groups. Topics include: Kodály's dance experiences, his practical dance knowledge, his work of exploring data of historical dance music, his role in the emergence of Hungarian ethnochoreology as a scholarly discipline, his critical views on the use of folk dance on stage, etc. In contrast to the earlier literature, this article no longer considers the Hungarian shepherds' horn signals as the inspirational sources for Bécsi harangjátek [Viennese Clock], a movement which imitates a musical clock in Kodály's Singspiel Háry János. The movement entitled Branle de village, part of seventeenth-century Austrian composer Johann Heinrich Schmelzer's Partita ex Vienna, contains some bars that bear a close resemblance to the repeated main motif of Kodály's Viennese Clock. It is safe to assume that Branle de village was Kodály's source of inspiration, given that there is evidence that he studied the DTÖ-collection of Schmelzer's works: he referred to this volume where he found a Styrian version of a Székely dance tune.
The Forgotten Youth of Sándor Veress
Authors: Dalos Anna
Published: June 2022

Although Sándor Veress achieved his first significant successes in Hungary and abroad at the turn of the 1930s and 1940s, musicological research still remains indebted to the detailed analysis of the composer's career related to the history of Hungarian music and cultural life. Based on press and archival documents, letters and recollections, and the historical literature of the period as well, the present study attempts to explore the socio-cultural environment that characterized and helped to unfold Veress's development. My study looks at the composer's network of contacts, his family ties and the political-ideological movements and relations with the Reformed Church that promoted his career, and examines their direct influence on Sándor Veress's works composed during this period, especially The Miraculous Flute (1937), the Japanese Symphony (1940) and Térszili Katica (1943).

Provinsi Lampung mempunyai potensi yang sangat besar untuk dikembangkan sebagai produsen ikan terbesar di Indonesia, baik perikanan air tawar, air payau (tambak udang dan bandeng), maupun air laut. Akan tetapi, angka konsumsi ikan Provinsi Lampung masih berada di bawah rata-rata nasional. Walaupun begitu, angka konsumsi yang masih terbilang rendah itu cukup menjadi bukti bahwa konsumsi ikan di Provinsi Lampung memiliki prospek yang baik dan menjanjikan bagi produsen ikan. Studi ini bertujuan untuk mengkaji proses diseminasi informasi sistem akuaponik, mengidentifikasi masyarakat sasaran kegiatan inkubasi, merumuskan metode/model sistem inkubasi melalui proses diseminasi informasi sistem akuaponik, melaksanakan sosialisasi metode/model sistem inkubasi melalui proses diseminasi, mengembangkan pabrik percontohan (pilot plant) kegiatan inkubasi melalui diseminasi, dan mengidentifikasi nilai tambah proses diseminasi informasi sistem akuaponik bagi pembudi daya ikan air tawar. Analisis data pada kajian ini dilakukan dengan metode analisis deskriptif kualitatif, analisis SWOT, dan analisis kelayakan finansial. Waktu penelitian ini dimulai dari waktu inkubasi itu sendiri. Title: Dissemination of Aquaponics System as Freshwater Fish Cultivation Income Alternatives in Central Lampung RegencyLampung Province has enormous potential to be developed as the largest fish producer in Indonesia, both freshwater fisheries, brackish water (shrimp and milkfish ponds) and marine fisheries.

A quantitative soil classification system (SCS) has been the aim of generations of Vietnam soil scientists. The SCS is a system of harmonizing the traditional Vietnam SCSs and creating a capability for international exchange. Up to now, there are three partially developed Vietnam official SCSs and three Vietnam semi-quantitative ones. This article aims to upgrade the Vietnam semi-quantitative SCS based on Vietnam's traditional pedogenetic (qualitative) and the World Reference Base for Soil Resources in 2014 (quantitative). For this purpose, a study was conducted to compare and analyze the correlation between the published Vietnam semi-quantitative SCSs and the official ones. Six SCSs were compared and analyzed. The results show that the Vietnam semi-quantitative SCS-2006 was selected to continue adapting and updating. Apart from the necessary adjustments, the study added 12 diagnostic horizons, 4 diagnostic properties, 2 diagnostic materials, 2 soil groups, 11 soil types, and 37 soil sub-types in the Vietnam semi-quantitative SCS-2006. Finally, the Vietnam semi-quantitative SCS includes 25 soil groups, 86 soil types, 492 soil sub-types with 30 diagnostic horizons, 7 diagnostic properties, 6 diagnostic materials, 58 qualifiers, and 9 criteria for defining soil varieties. The system keeps the traditional aspects of Vietnam's official SCSs and allows the exchange of international soil information.
Koniec specjalnych relacji Stanów Zjednoczonych z Arabią Saudyjską?
Authors:   Uniwersytet Kazimierza Wielkiego w Bydgoszczy, Gwiazda Adam

The Saudi special relationships with the U.S., unlike that of the U.S. with Israel, are mutually beneficial. Saudi Arabia sells about 10 million barrels of oil a day and all those transactions are denominated in American dollars, which helps that currency to perform the role of the currency of account (world, s currency) and has been of crucial help to the American ambition to dominate the global economy. On the other hand the United States did its part to uphold the relationship be granting the security to Saudi Arabia and other Gulf oil states. This was demonstrated for example in 1990 during Iraqi attack on Kuwait, that also menaced Saudi Arabia. At that time the U.S. deployed 400,000 troops in Saudi Arabia and expelled Iraqi troops from Kuwait. The priority of American foreign policy in that region has been to keep Gulf oil in friendly hands. Since the increase of the production of shale oil in the United States that priority has been less important. Another factor which has exerted an influence on the nature of the U.S.-Saudi relationship was the signing the permanent agreement with Iran in July 2015 on the limitation of the Iranian nuclear program and normalization of political-economic relations with the West. This has led to further worsening of the U.S.-Saudi Arabia alliance which has always been like a ”marriage of convenience” where behind the façade of friendship and harmony there is cold calculation of benefi ts and losses. That alliance will last as long as the potential benefi ts will still be bigger than possible losses.
Narracje na temat aneksji Krymu na łamach „Foreign Affairs” w świetle teorii stosunków międzynarodowych
Authors:   Uniwersytet Kazimierza Wielkiego w Bydgoszczy, Walewicz Piotr
Published: June 2022

Publications in western specialized journals which describe the Russian Federation’s international behavior have always followed a certain paradigm of international relations. The article is an analysis of opinions and beliefs held by commentators and analysts writing for „Foreign Affairs”, based on their publications about the annexation of Crimea by the Russian Federation on march 2014. They have been scrutinized using three predominant theories of international relations: realism, liberalism and constructivism. The research proved that western commentators and analysts writing about the annexation of Crimea usually present a single paradigm of international relations. Moreover, they believe it to be the only effective tool in explaining countries’ foreign policy, thereby depreciating the value and usefulness of other paradigms.

In this article the authors examine the impact of integration processes on the competitiveness of national economies of the participating countries of the Eurasian Economic Union (EAEC). Any integration, including integration within the EAEC affects the economy of participants in two ways: on the one hand it favorably promotes multilateral mutually beneficial business contacts, and on the other hand, it feels the strength, competing with each other, the individual national economies. The authors comprehensively investigated the current situation and problems of the EAEC with the use of different methods of political analysis (comparative and system analysis, content analysis, event analysis, SWOT-analysis, and others.). In a sufficiently sharp polemical form, based on credible evidence materials, the article shows not only the integration of interaction, but also features of competition within the EAEC, the causes of conflict, as well as the consequences that resulted in the devaluation of ruble and dumping prices in Russia, which in turn all have a negative impact on competitiveness of the economies of Kazakhstan and Belarus.

Terrorism is harmful to democratic governments and societies. In addition to the visible and the direct effects of attacks on bystanders, aim bombers are undermining democratic values, including the weakening of confidence in state institutions and laws that regulate their functioning. As a result of the use of violence can permanently give birth to create a socio-political divisions, antagonize certain entities and groups, and thus provoke conflicts thus destroying the existing compromises, agreements or arrangements between the parties concerned. In matters of international terrorism it is not only a challenge for the rule of law, but because it also applies to relations between states, poses a serious threat to security and stability.

The aim of this article is to present the biography of a film director- L. Riefenstahl, with an emphasis on her propaganda documentary works by the example of two documentaries: “Triumph of the Will” and “Olympia”. The thesis stated by the authors of this article is about creating reality by L. Riefenstahl. The authors present the propaganda techniques used by the director in her documentaries. The authors base this work on the analysis of audiovisual productions, historical method and finally- deduction. L. Riefenstahl was the artist with a great experience. As the director, not only was she innovative and unconventional, but also she was able to use and transfer her experience gained on other fields of her own life onto audiovisual productions. Therefore, the critics value Riefenstahl’s works due to their innovatory character and technical nuances. Although L. Riefenstahl is one of the most talented documentary directors, still, vast majority of her films were vile propaganda at the service of the 3rd Reich. Worshipping Hitler, love of symbols and faith in NSDAP is highly visible in Riefenstahl’s works.
