Objectives

Brown adipose tissue (BAT) is important in the maintenance of cardiometabolic health in rodents. Recent reports appear to suggest the same in humans, although if this is true remains elusive partly because of the methodological bias that affected previous research. This cross-sectional work reports the relationships of cold-induced BAT volume, activity (peak standardized uptake, SUVpeak), and mean radiodensity (an inverse proxy of the triacylglycerols content) with the cardiometabolic and inflammatory profile of 131 young adults, and how these relationships are influenced by sex and body weight.

Design

This is a cross-sectional study.

Methods

Subjects underwent personalized cold exposure for 2 h to activate BAT, followed by static 18F-fluorodeoxyglucose PET-CT scanning to determine BAT variables. Information on cardiometabolic risk (CMR) and inflammatory markers was gathered, and a CMR score and fatty liver index (FLI) were calculated.

Results

In men, BAT volume was positively related to homocysteine and liver damage markers concentrations (independently of BMI and seasonality) and the FLI (all P ≤ 0.05). In men, BAT mean radiodensity was negatively related to the glucose and insulin concentrations, alanine aminotransferase activity, insulin resistance, total cholesterol/HDL-C, LDL-C/HDL-C, the CMR score, and the FLI (all P ≤ 0.02). In women, it was only negatively related to the FLI (P < 0.001). These associations were driven by the results for the overweight and obese subjects. No relationship was seen between BAT and inflammatory markers (P > 0.05).

Conclusions

A larger BAT volume and a lower BAT mean radiodensity are related to a higher CMR, especially in young men, which may support that BAT acts as a compensatory organ in states of metabolic disruption.

. Introduction. Today, the globalization of various spheres of human functioning (economy, politics, etc.) is one of the society trends. Sport as a social practice is also intensively globalized, and this is most clearly seen in the example of professional sport. In this area, today the laws of development (commercial, sports, etc.) are spreading to Olympic and non-Olympic sports, and more globally – the level of professional sport affects the economic development of entire countries and, in many respects – the formation of society. Purpose: to characterize the specifics of globalization of social practice «professional sport» in modern conditions of development. Material and methods. The study was based on the processing of modern scientific articles on the development of professional sport in its various aspects, as well as popular science sources of information and materials on the official websites of leading professional sport organizations. Research methods: analysis and synthesis, historical method, system approach, comparison. Results. Today, the globalization of professional sport is taking place in the following areas: expanding cooperation with media corporations and sponsors; internationalization and commercialization (increase in the number of organizations that oversee various sports and, accordingly, the number of profitable competitions); maximum use of Internet technologies for the promotion of sport products and the development of e-sports within professional sport leagues; increase match attendance by ensuring effective marketing policies; expanding cooperation with the authorities at the state and local levels on mutually beneficial terms; bringing championships beyond national borders (typical of the North American model of professional sport, as for the European throughout the history of its development the emphasis has been and remains on the leading importance of international competitions), etc. Conclusions. Today, due to the processes of society globalization, which actively influence the field of professional sport, this social practice undergoes internal globalization, which can be traced both in purely sport (expanding the calendar of competitions, going beyond national championships, etc.) and commercial areas (expanding cooperation with sponsors, media companies, etc.), technological (introduction of modern technologies, launching a series of cyber competitions, etc.) political (expanding cooperation with state and local authorities), and etc. directions.

Quinine, a naturally happening alkaloid initially utilized for the treatment of muscle cramps, is currently most usually utilized to treat malaria. Symptoms of poisonous quinine, called Cinchonism, include wooziness, tinnitus (ringing in the ears), blurred vision, nausea, vomiting, serious adverse reaction to excessive quinine use, vision impairment and deafness. This research aimed to obtain more polar quinine derivatives using reactions with sulfuric acid and nitric acid to reduce toxicity. The reactions were performed analogously to the procedures reported in the literature. The characterization of reaction products utilizing proton (1H) and carbon-13 (13C) nuclear magnetic resonance (NMR) spectroscopy showed that the reaction using reagents led to nitration of the quinoline ring with the yields of 7.09 %. The IC50 value of >10.000 μg/mL was obtained from the antimalarial test against Plasmodium falciparum 3D7. The IC50 values proved that the synthesis products (6-Methoxy-2,5-dinitro-quinoline-4-yl)-(5- vinyl-1-aza-bicyclo[2.2.2]oct-2-yl)-methanol) was not potential for malaria treatment.

There is often a drawback during the determination of Eu in aqueous solvents using the voltammetric method. The current signal from water can reduce that of the element, which causes difficulty while separating the Eu signal from other rare earth elements (REE). Therefore, this study used acetonitrile as a solvent due to its high electrical conductivity and wide potential range. The optimum conditions for the determination of Eu in acetonitrile using the Box-Behnken design include 74.56 seconds deposition time, 0.125 V amplitude modulation, and -2.0 V potential deposition. The platinum electrode's performance showed a recovery value of 98.91% and accuracy and precision (in %RSD) of 96.67% and 1.11%, respectively. Furthermore, detection and quantitation limits of 0.6 mg/L and 5.1 mg/L were recorded from the analysis. It concluded that the differential pulse voltammetry method was applied to determine the presence of Eu in acetonitrile.

Recently, the Indonesian industry has been rapidly developed and affects the number of heavy metal ions waste such as iron (II). Iron (II) is dangerous to the environment because it is harmful to aquatic systems and carcinogenic. This research used activated silica/lignin to remove iron (II) in water. The activated silica/lignin was isolated from rice husk and activated by sodium periodate with a 10% weight of lignin in the range of pH of 2–5 at 55 °C. Then its specific surface area was analyzed with the methylene blue adsorption method. It is found that the condition in pH 2 showed the best isolation and activation condition to achieve the lowest impurity (cellulose and hemicellulose) in silica/lignin composite. Furthermore, the activated silica/lignin composite, isolated in pH 2, has a specific surface area of 366.6372 m2/g with the highest adsorption value of 1.1825 mg g-1 for iron (II) ions solution (5 ppm) within a contact time of 90 minutes. Moreover, the adsorption kinetics followed the pseudo-second-order kinetic model, also the adsorption isotherm fitted with the Freundlich model. This research showed that activated silica/lignin could be used as an alternative of environmentally friendly material for iron (II) removal in water.

Actinobacillus pleuropneumoniae (App) is the etiological agent of porcine pleuropneumonia. The purpose of the study was to present a serological report on App prevalence among pigs in industrial farms in Bulgaria. Seventy-two pigs from four industrial farms in four districts of Bulgaria – Eastern Bulgaria (Razgrad and Yambol districts) and Western Bulgaria (Lovech and Sofia districts) were included. Animals were divided in two age groups: weaners and fattening pigs. A commercial enzyme-linked immunosorbent assay (ELISA, INgezim APP MIX, Eurofins Ingenasa, Madrid, Spain) for the detection of antibodies against App parasuis in porcine serum was used. Microtitrе plate was coated with App antigen of the serovars 1, 2, 9 and 11. Positive results for anti-App antibodies were detected in 32 (44.4%) of all 72 tested sera. The overall seropositivity in weaners and fattening pigs was 22.2% (8/36), and 66.7% (24/36), respectively. The highest App seropositivity in pigs was found in Eastern Bulgaria - 61.1% (22/36; P<0.001) in comparison to App seropositivity in Western Bulgaria – 27.8% (10/36; P=0.137). This study on anti-App prevalence among pigs in Bulgaria gives new insights on App epidemiology in our country.

Published: June 2022

Toxoplasma gondii and Neospora caninum, two obligatory intracellular protozoan parasites, are important causes of neonatal mortality and abortion in farmed ruminants worldwide. Previously, protozoan abortions in small ruminants were attributed to T. gondii, but the role of N. caninum in these abortions was uncertain. The aim of this study was to investigate the role of T. gondii and N. caninum in ovine abortion in Urmia, northwest of Iran using a molecular method. Overall, 130 placenta and brain samples of aborted ovine foetuses were collected. Extracted DNA from placenta and CNS tissues of the aborted foetuses were analysed using PCR with primers specific for T. gondii and N. cani­num. The association of the frequency of T. gondii and N. caninum infection of aborted foetuses with age and breed in flocks was also studied. The results showed that out of the 130 examined ovine foetuses, 5.3 and 2.3 % were PCR-positive for T. gondii and N. caninum DNA, respectively. In this study, no significant differences were recorded relating to Toxoplasma and Neospora infection in different age groups in flocks and among sheep breeds included in the present study (P>0.05). The results of this study proved the importance of T. gondii and N. caninum as reasons of abortion in the studied area.

Published: June 2022

Fusarium spp. are phytopathogens causing fusarium head blight in wheat. They produce mycotoxins, mainly fumonisins, deoxynivalenol, and zearalenone. The study was conducted during two growing seasons (2020 and 2021) at the experimental field and laboratories of the Hungarian University of Agriculture and Life Sciences (MATE). The aim of the study was to determine the influence of growing season, nitrogen fertilisation, and wheat variety on Fusarium infection and mycotoxin production in wheat kernel. Zearalenone was not detected during the two growing seasons and deoxynivalenol was only detected in 2020. The results indicate that nitrogen fertilisation and wheat variety did not have statistically significant influence on Fusarium infection and mycotoxin production. The growing season had statistically significant influence on Fusarium infection and fumonisins production due to higher rainfall in 2021 compared to 2020 during the flowering period when the wheat spike is the most vulnerable to Fusarium infection.
Two novel titanium alloys for medical applications: Thermo-mechanical treatment, mechanical properties, and fracture analysis
Authors: Haase Fabian , Siemers Carsten , Rösler Joachim
Published: June 2022

Titanium alloys are ideally suited for use in implant or osteosynthesis applications due to their good mechanical properties, corrosion resistance, and biocompatibility. In terms of higher strength applications, Ti–6Al–4V and Ti–6Al–7Nb are frequently used. However, both alloys contain the alloying elements aluminum and, in the former case, vanadium, which could have toxic effects on the human body. Therefore, in the present study, two novel, medium- to high-strength titanium alloys, Ti–0.44O–0.5Fe–0.08C–0.4Si–0.1Au and Ti–0.44O–0.5Fe–0.08C–2.0Mo, have been developed on the basis of CP-Titanium Grade 4. They only contain alloying elements, which are either already present in the human body or which are biocompatible. Dedicated thermo-mechanical treatments were developed for both alloys and the resulting mechanical properties were evaluated by tensile and (partly) fatigue tests with subsequent fracture surface analysis. Results reveal that these new alloys show excellent mechanical properties and, therefore, might be a possible alternative for Ti–6Al–4V for use in medical applications.

Published: June 2022

Shallots are bulb-shaped commodities that are difficult to maintain in new conditions because they are easily damaged. An effective effort to prevent deterioration of food quality during storage is by coating it using nano chitosan. The effectiveness of nano chitosan is influenced by particle size which related to the ratio of chitosan and STPP (sodium tripolyphosphate). This study aimed to determine the effect of nano chitosan coating with the addition of different ratios of chitosan and STPP and the appropriate ratio of chitosan and STPP on nano chitosan as a coating to maintain the quality of shallot bulbs (Allium ascalonicum L. var. Bauji). This study used a completely randomized design (CRD) method with four treatments and five replications. The treatments of this research were P0= Control, PI= Nano chitosan ratio of chitosan: STPP 1:3, P2= Nano chitosan ratio of chitosan:STPP 1:4, and P3= Nano chitosan ratio of chitosan:STPP 1:5. The variables of this study were the percentage of damage, the percentage of diameter shrinkage, weight loss, color, hardness, and moisture content. Data were analyzed using the ANOVA test and continued with the DMRT test. The application of nano chitosan coating on shallot bulbs could reduce damage, shrinkage of tuber diameter, weight loss, color, hardness, and decrease in water content better than the control treatment. The best results were shown by treatment P3 (1:5) with a percentage of damage of 8%, diameter shrinkage of 20.20%, weight loss of 18.40%, total color change of 54.45, hardness of 226.23 N, and a decrease in water content of 4.65% at the final water content of 79.09%.

Published: June 2022

Studies on morphology, growth, and reproduction have been carried out on wild Javaen barb, but there was no information on its digestive capacity; therefore, the research was conducted to determine protease and amylase activities in the digestive tract. This study used a total of 50 barbs with body weights between 13.56 -128.93g / fish. The measurement of enzyme activity was carried out using the spectrophotometer method. The results showed that differences in fish size resulted in differences in protease activity, but not for amylase. Fish with a small size have a higher protease activity than fish with a larger size. The protease activity did not differ between pH 6.9 to 10.0 but was higher than pH 12.5. Protease activity also did not vary between the anterior and posterior intestine and between 30-50°C. Amylase activity also found no difference between the anterior and posterior intestine, but there was a difference in activity between temperatures of 30-50°C. In conclusion, protease activity occurs in a neutral to alkaline environment, and there were differences in protease activity between different body sizes but not between intestinal segments. Amylase activity occurs throughout the intestine and decreases at temperatures of 50°C.

Translanguaging in online language teaching
Authors: Wimalasiri Apsara , Seals Corinne A
Published: June 2022

The Covid-19 pandemic has restricted social interactions to online spaces, shifting usual face-to-face classrooms to online platforms. This article investigates how teachers and adult learners in an English as an additional language classroom experience these changes, solve problems that arise and negotiate their teaching and learning methods in an online space. Specifically, we focus on a case involving a teacher practising in an online Zoom English language classroom during the 2020 Covid-19 lockdown in Aotearoa New Zealand. The data for this article come from a semi-structured narrative interview, four hours of online classroom observations and a stimulated recall session. Data analysis was conducted using the Interactional Sociolinguistics approach to discourse analysis. Findings from this study show how the teacher shifted to an online space, overcoming initial struggles and negotiating her teaching methodologies, including making use of new technological advancements of the online platforms she used. Additionally, the data highlight the teacher’s efforts to maintain pedagogical translanguaging in her online classes as an effective language teaching strategy. However, there are also restrictions in her awareness of benefits of using spontaneous translanguaging in the language classroom, highlighting that her choices do not always align with translanguaging as a form of social justice.
Foreign-local teacher-learners in the digital classroom

Published: June 2022

Prior to the Covid-19 pandemic outbreak in 2020, the University of Oslo (UiO), Norway, operated largely through in-person teaching, with minimal use of digital platforms. While online teaching did not change the multilingual nature of the academic community at UiO, nor the everyday Scandinavian-English translanguaging practices of our classrooms, it did bring to light the need to explicitly discuss forms of engagement and participation, including language use. We are both sociolinguists, learners of Norwegian and work migrants to Norway who have been members of UiO for over five years; as such, we negotiate positions as both foreign and local, and as teachers as well as learners. In this article, we take an autoethnographic practitioner inquiry perspective to investigate how our pedagogical translanguaging practices in digital modes of teaching have been shaped by (a) localised language hierarchies, (b) institutional demands/structures, (c) students’ needs and (d) our teaching philosophies. Drawing on our experiences in online teaching over three semesters, we analyse the challenges we have encountered and how attempting to address these challenges through pedagogical translanguaging practices has led to new insights into the nuances of Scandinavian repertoires and to pedagogical relationships based on a non-hierarchical understanding of the roles of lecturers and students. We have found it useful to draw attention to the everyday translanguaging of Norwegian society and to explicitly legitimise pedagogical translanguaging and translingual literacies in our classes as a way to foster metalinguistic awareness and better communication in the online classroom. At the same time, we acknowledge that the particular challenges posed by this digital transition and the dominant role of English in Scandinavian higher education still need further attention as we attempt to create teaching and learning spaces in online platforms that encourage the use of students’ and teachers’ linguistic repertoires.

En el marco más amplio de discusión sobre las virtualidades posibles del precedente judicial en la actividad jurisdiccional del Tribunal Supremo de la Signatura Apostólica, el presente trabajo se centra en ciertos aspectos de su jurisprudencia en términos de legitimidad y en su función fundamental de observancia exacta e interpretación uniforme de la ley. Al determinar la especificidad de algunas sentencias firmes en las que, hipotéticamente hablando, se podría encontrar la ratio decidendi asumida como supuesto indispensable del precedente, el artículo destaca algunas ventajas de poder juzgar en base al precedente. Partiendo específicamente del análisis de su actividad judicial, se ha podido identificar que el enjuiciamiento por precedente es por el momento un postulado de lege ferenda.

An Analysis of Exchange Rate Pass-Through to Domestic Prices: Evidence from Turkey
Authors:   Pennsylvania State University, OZDOGAN Zeliha
Published: June 2022

Assessing the impact of exchange rate shocks on domestic prices (Exchange Rate Pass-through) has a crucial role, particularly for the inflation targeting countries. This paper aims to clarify some aspects of ERPT to domestic prices in Turkey, an emerging country. Specifically, this study investigates if ERPT in Turkey is complete and how the behavior of ERPT has changed after the adoption of a flexible exchange rate regime in 2001. A Vector Auto Regression (VAR) framework is used to analyze the impact of exchange rate shocks on CPI Inflation. This study provides empirical evidence on the incompleteness and the pattern of ERPT on Turkey’s CPI inflation based on the VAR Model. The findings demonstrate that ERPT is not only incomplete but also has a different pattern during the floating exchange rate period. The pass-through has decreased from 2001 to 2017, and it has increased dramatically after 2017 to a large extent because of very high inflation and high exchange rate volatility in this period.

Magnetic nanoparticles play an important role in rapidly developing advanced branches of science and industry, e.g. fabrication of magnetic storage media, synthesis of ferromagnetic liquids, medicine and chemistry. One problem faced in the usage of magnetic nanoparticles is their high chemical activity leading to oxidation in air and agglomeration. The chemical activity of magnetic nanoparticles stems from the contribution of their large specific surface to volume ratio. Carbon coating of nanoparticles reduces the interaction between nanoparticles. FeCoAl/C metal-carbon nanocomposites have been synthesized using IR pyrolysis of polymer / metal salt precursors. The effect of synthesis temperature (IR heating) in the range from 500 to 700 °C on the structure and composition of the nanomaterials has been studied. We show that the forming particles are the FeCoAl ternary solid solution with a FeCo based bcc lattice. An increase in the synthesis temperature from 500 to 700 °C leads to an increase in the coherent scattering region of three-component nanoparticles from 5 to 19 nm. An increase in the aluminum content from 20 to 30 % relative to Fe and Co results in an increase in the size of the nanoparticles to 15 nm but this also entails the formation of a Co based solid solution having an fcc lattice. An increase in the nanocomposite synthesis temperature and a growth of the relative Al content as a result of a more complete carbonization and the structure-building effect of metals reduce the degree of amorphousness of the nanocomposite carbon matrix and lead to the formation of graphite-like phase crystallites having an ordered structure. The effect of synthesis temperature and relative content of metals on the electromagnetic properties (complex dielectric and magnetic permeability) of the synthesized nanocomposites has been studied. Synthesis conditions affect the radio absorption properties of the nanocomposites, e.g. reflection loss (RL) in the 3—13 GHz range.
Features of the superposition of ultrasonic vibrations in the welding process

Introduction. The main problem in obtaining welded joints is the nonuniform heating of the joint zone, which leads to differences in the structure and properties of the weld metal and the base metal. One of the ways to intensify the welding process is the use of ultrasonic vibrations. As a result of the analysis of methods for introducing ultrasonic vibrations into the melting zone, a method of superimposing vibrations on the elements to be welded was chosen for experimental studies. This method makes it possible to influence the welded elements throughout the entire welding cycle from the melt bath to complete crystallization of the metal. Methods. Experimental studies were carried out on plates made of carbon structural steel St3 (ASTM A568M, AISI 1017, DIN 17100) and aluminum deformable non-hardened alloy AMg4 (EN AW-5086, AW-AL Mg4, 5086). As a source of oscillations, a rod magnetostrictive oscillatory system was used, the end of which was rigidly fixed on one of the welded plates. To determine the places of application of the oscillation source and the welding zone, a calculation method is proposed based on the equality of the resonant frequencies of the used oscillatory system and the natural frequency of bending vibrations of the welding component. It is shown that the optimal places for the application of vibrations and welding will be the antinodes of oscillations, which have the maximum amplitude. Welds were obtained by the method of semi-automatic gas metal arc welding. Results and Discussion. Microstructural study of obtained samples showed a significant decrease in the proportion of dendritic segregation. The changes in the structure are the result of the effects that occur in the liquid melt when ultrasonic vibrations are introduced. The main effects are sound pressure, cavitation and acoustical streaming. The structure change mechanism consists in the dispersion of growing dendrites and crystallization nuclei under the action of shock waves and cumulative jets that occur when cavitation bubbles collapse. The formed fragments of dendrites are new crystallization nuclei that propagate through the melt pool under the action of acoustic currents. Then the process is repeated. The resulting effects affect the kinetics of the crystallization process – the degree of supercooling increases, the number of crystallization nuclei formed per unit time increases, and the rate of its growth decreases. Changes in the structure of the weld metal lead to an increase in the quality of the welded joint, which reduces welding deformations, increases the tensile strength and significantly increases ductility.

Mitochondrial bioenergetics plays a key role in a variety of basic cellular processes, such as energy production, nucleotide biosynthesis, and metabolism. Not only the basic system of cell production and death (apoptosis), it is also necessary for embryonic development. Besides, mitochondrial bioenergetics is involved in the adaptive process and its gene products in species, as well as in the formation of animal reproductive disorders.
