Published: December 2019

Free radicals play a critical role in causing hemorheologic abnormality which is highly correlated with cardiovascular disease and stroke. In this study, we established an in vitro model to evaluate the influence of free radical attacks on hemorheological parameters. A well-sealed chamber with hyperbaric oxygen was used to simulate an environment of free radical attacks. Hemorheological parameters, including whole blood viscosity, erythrocyte membrane lipid peroxidation, and erythrocyte deformability, were investigated. We then used the in vitro model to evaluate the anti-free radical effects of some well-known catechin antioxidants, such as epigallocatechin gallate (EGCG), (-)-epicatechin 3-gallate (ECG), and (-)-epigallocatechin (EGC) on abnormal hemorheological parameters induced by hyperbaric oxygen. The results show that an increase in oxygen partial pressure (1.0, 1.5, 2.0 and 2.5 atm) and exposure time (4, 8, 12 and 16 h) resulted in elevated free radical formation and viscosity of whole blood, enhanced lipid peroxidation in erythrocyte membranes, but decreased erythrocyte deformability. In addition, EGCG, ECG, and EGC (0.1, 0.5 and 1.0 μM) effectively ameliorated hemorheologic abnormality and enhanced erythrocyte deformability. Therefore, this study has provided an in vitro hyperbaric oxygen model to rapidly screen or assess the efficacy of functional foods and drugs in the prevention or improvement of hemorheologic abnormality.

Published: December 2019

We tested the effects of submaximal exercise on blood viscosity (ηb), nitric oxide production (NO) and hemodynamics. Relationships between the exercise-induced changes that occurred in these parameters were investigated. Nine subjects performed exercise for 15 min at 105% of the first ventilatory threshold. Mean arterial pressure (MAP) and cardiac output (Qc) were measured, allowing the determination of systemic vascular resistance (SVR). Blood was sampled at rest and at the end of exercise. The ηb was determined at high shear rate and was used to calculate systemic vascular hindrance (VH). NO production was estimated by measuring plasma concentrations of NO stable end products (NOx). Qc, MAP, ηb and NOx, increased with exercise, whereas SVR and VH decreased. The changes between rest and exercise were calculated and tested for correlations. We observed: 1) a positive correlation between the increase in ηb and the increase in NOx; 2) a negative correlation between the increase in NOx and the decrease in VH; 3) a negative correlation between the increase in ηb and the decrease in SVR. Although the increase in Qc and blood flow during exercise probably promoted NO production due to shear dependent stimulation of the endothelium, the present results also support that the rise in ηb during exercise may be necessary for NO production and adequate vasodilation.

Published: December 2019

Hypercholesterolemia is one of the cardiovascular risk factors sensitive to preventive and control interventions. Here we created a hypercholesterolemia model to investigate the effect of the long term aerobic exercise (swimming) on the hemorheology of rats fed with high-fat diet. We found that the rats fed with high-fat diet developed hypercholesterolmia and hepatic steatosis and their hemorheological and coagulative properties were all impaired as compared to those of the rats fed with standard diet. But after exercise, the total cholesterol and triglyceride in the plasma were significantly decreased and the severity of hepatic steatosis were reduced. Exercise greatly improved the erythrocytes' hemorheological properties, including deformability, electrophoretic mobility and osmotic fragility. Exercise also markedly lowered the activated partial thromboplastin time (APTT) but had moderate effects on other coagulative parameters. The high oxidative stress level, as indicated by plasma MDA concentration, in rats with high-fat diet was significantly attenuated to the normal level after exercise. The present study suggests that long term aerobic exercise could remarkably improve the abnormal hemorheological property and the oxidative stress in rats with hypercholesterolemia.

This study tested the hypothesis that trained sickle cell trait (SCT) carriers are not subjected to greater risk of rhabdomyolysis or renal failure in response to moderate submaximal exercise than subjects with normal hemoglobin (CONT). Blood markers in 11 trained SCT carriers and 12 control counterparts were measured before and after 40 min of exercise at 55% of peak power output (Ppeak) conducted in thermoneutral environment. Body weights decreased with exercise in the same proportion in the two groups (from 65.1 ± 7.0 kg to 64.1 ± 7.0 kg and from 70.2 ± 6.6 to 68.6 ± 6.6 kg at the end of exercise in SCT and CONT, respectively). Heart rate and rectal temperature increased in the two groups in response to exercise, but the groups remained closely matched. Serum urea, CRP, CK and LDH were similar in the two groups and remained unchanged in response to exercise. Creatinine, Na+, K+, Cl− and myoglobin concentrations increased above baseline in response to exercise, with changes of the same magnitude in the two groups. In summary, the results of the present study suggest that moderate submaximal exercise is not unsafe from a biochemical point of view for sportsmen carrying SCT.

Published: December 2019

Pregnancy in sickle cell disease (SCD) has been associated with increased complications such as vaso-occlusive crises, severe anemia and foetal loss. It has been proposed that the sickling of red blood cells (RBCs) inside the placenta circulation could participate to these complications. The present study investigated the adhesion of sickle RBCs on human trophoblast-derived cell and its extracellular matrix. Results demonstrated 1) similar adhesion of sickle RBCs and healthy RBCs to trophoblast but 2) a greater adhesion of sickle RBCs to the extracellular matrix of trophoblasts as compared with healthy RBCs. This greater adhesion could partly involve the Lu/BCAM glycoproteins and could participate to the complications reported in SCD pregnant women.
Use of hydroxyethyl starch for inducing red blood cell aggregation

Published: December 2019

Aggregation of human red blood cells (RBC) remains of biological and clinical interest. Replacement of plasma proteins by polymers to induce RBC aggregation may help to unravel the fundamentals of the aggregation process. Two theories exist to explain RBC aggregation mechanisms: a depletion and a bridging theory. RBC aggregation induced by hydroxyethyl starch (HES) increases with polymer size, which suggests that aggregation is induced via the bridging theory. In this study, the electrophoretic mobility (EPM) was measured to investigate RBC aggregation induced by 200 kDa HES polymers. Also, we evaluated if these polymers were useful for demonstrating aggregation differences between RBCs from healthy and type-1 diabetes mellitus (T1DM) subjects. Our results demonstrate that EPM values of RBCs in 200 kDa HES solutions were less negative than could be predicted by the viscosity of the suspension, supporting the bridging theory. Furthermore, aggregation analysis using the LORCA demonstrated that 200 kDa HES solution enhanced RBC aggregation of healthy and diabetic subjects similarly as standard 500 kDa dextran solutions. In conclusion: our data supports the bridging mechanism underlying 200 kDa HES induced RBC aggregation. In addition, both polymers are useful for demonstrating cellular induced aggregation differences between RBCs from healthy and T1DM subjects.
The effect of physical activity on haematological predictors of cardiovascular risk – evidence of a dose response
Authors: Adams Rachel A. , Higgins Tim , Potter Stephen , Evans Shelley-Ann
Published: December 2019

Cardiovascular disease is a major cause of morbidity and mortality in the developed world. Large epidemiological studies have reported a strong association between increases in haematological factors and increased cardiovascular risk. Haematological risk factors predicted cardiovascular disease at least as strongly as traditional risk factors such as blood lipid concentrations. Lifestyle factors such as physical activity level could significantly reduce risk. The aim of this study was to determine the effect of physical activity level on haematological predictors of cardiovascular risk. Healthy subjects (156) were recruited. Physical activity in subjects was assessed by IPAQ physical activity questionnaire. Blood was collected and blood cell counts were determined by automated cell counter; neutrophil elastase was determined by ELISA. Increased levels of physical activity were associated with reduced red cell (p = 0.001), white cell (p = 0.002) and platelet counts (p = 0.001) and with reduced plasma neutrophil elastase concentration (p = 0.001). There was a continuous linear relationship between increase in physical activity and decrease in haematological risk factors. Hence, the authors conclude that increased levels of physical activity improve the flow properties of blood and thus reduce the risk of developing cardiovascular disease. Even small increases in activity result in some reduction in cardiovascular risk.

Published: December 2019

This study explores the factors of study abroad programs that contribute to cultivating intercultural competence. Through an empirically based quantitative examination of 303 Japanese study abroad students, it attempts to gain an understanding of the factors that enhance the development of intercultural competence. Considering that many previous studies worked with students in English-speaking countries, this study examines whether an investigation of Japanese students would yield similar results, given the different context. The primary findings show that program type, prior local language proficiency, and pre-departure orientation are predicted to have significant impacts on intercultural competence. The findings clearly demonstrate the importance of empirically-based arrangements of study abroad programs based on student and program profiles to enhance students’ intercultural competence.

Published: December 2019

This article assesses changing interest from India in Canadian versus U.S. universities since the 2016 U.S. presidential election, as measured by search activity reports from Google Trends. The findings indicate a rise in Indian interest toward Canadian versus U.S. universities was underway before the election. After controlling for this trend effect, there remains widespread evidence of a substantial shift in interest toward Canadian universities with search activity rising 70%–85% for Canadian versus U.S. universities in the postelection period. This shift in interest toward Canadian universities shows no sign of dissipating. Canadian universities are likely to make further enrollment gains of Indian students versus U.S. counterparts in upcoming recruiting classes.
Italy - Crimea: history and modernity

On 18 May 2016, in Venice, the Council of the Veneto Region was the first institution in the European Union that recognized the reunification of Crimea with Russia. This resolution paved the way for the same action by other Italian regional institutions: on 29 June 2016 in Genoa, the Council of the Liguria Region approved the recognition of thenew Crimean status; on 5 July, was the turn of the Lombardia Region. It is no coincidence that Veneto and Liguria have taken this step, but there are very specific historical reasons. Crimea in the Middle Ages hosted Venetian and Genoese colonies.
The Crimean Issue: Official French Policy under Criticism from Domestic Elites

Published: December 2019

De jure recognition of Crimea as a part of Russia’s territory is not on the agenda of political discussions in France. Or, a noticeable part of French society, including its elite groups, does not share the vision of Ukrainian and Crimean events built on anti-Russian postulates. The Euro-Atlantic policy, greatly endorsed by the official leadership of the country and its dominant elites, invites skepticism and criticism not only within business environment, but also from French political, diplomatic, military and expert circles. Moreover, controversy on these issues highlights a new ideological division that is pushing back the classic left-right cleavage.

Predicting the Temperature and Composition – Dependent Density and Viscosity of Diesel Fuel – Ethanol Blends
Authors: Todoruț Adrian , Molea Andreia , Barabás István
Published: December 2019

Density and viscosity are very important fuel properties which have a major influence not only on the fuel production, transportation and distribution processes but also on the processes that take place in an internal combustion engine. Developing robust and high precision density and viscosity models for stabilized diesel fuel – ethanol blends helps the production of fuel to adhere to the quality requirements regarding density and viscosity and the modeling and simulation of injection and combustion processes. For modeling the density and the viscosity of diesel fuel – ethanol blends, five mixtures were prepared with ethanol content up to 15 % (v/v) and were stabilized by adding tetrahydrofuran as a surfactant at room temperature. The temperature-dependent density and viscosity of the blends were measured at four different temperatures (0, 15, 40 and 50 °C) using an SVM 3000 type apparatus. Based on experimental data, several mixing rules were fitted to them and three new models were developed, of which two need only one experimental value. These models yield very good accuracies, presenting average relative deviations of 0.0604 % in the case of density and 3.8931 % in the case of viscosity.

PROJECT BASED LEARNING IN TRANSLATION CLASSApandiProdi Pendidikan Bahasa Inggris, FKIP Unswagati CirebonEmail: aapandi5@gmail.comDevi Siti Sihatul AfiahProdi Pendidikan Bahasa Inggris, FKIP Unswagati CirebonÂ Â AbstractThis study aims to identify student learning experiences in the Indonesian-English translation class. This study uses a case study approach with data collection methods in the form of observations, interviews and questionnaires. Observations are made to obtain data sources from direct sources. Interviews were conducted to find out whether the places visited had historical stories, legends or folktales that could be translated into English, and also to find out the obstacles or challenges faced during learning using PBL. A questionnaire was used to identify learning experiences in the Indonesian-English translation class using PBL. Respondents were students of the 6th semester of the English language education program who took part in the English-Indonesian translation course. Data is presented in the form of descriptive explanations and also supported by graph data to facilitate the presentation. This study shows that the use of PBL provides benefits in forming independent learners, improving critical thinking and can improve attitudes in collaboration with peers. However, there are still obstacles and challenges in translation courses using PBL, namely at the beginning of the lecture in the form of less preparation time, adaptation with group mates and also the location of observations that are located some distance from the campus or where students are, and there are difficulties in translating cultural words found.Key words: PBL, Translation, Learning Experience
A organização do trabalho, o risco psicossocial e o adoecimento
Authors: Pereira Reis Odete
Published: December 2019

As transformações pelas quais o mundo do trabalho vem passando, em especial o surgimento de novas tecnologias, a globalização e a reestruturação produtiva, fizeram com que surgissem também novas formas de organização do trabalho. Esse artigo tem como objetivo analisar e realizar reflexões acerca das formas de gestão e organização do trabalho que tem como base, entre outros, a cobrança de metas abusivas e o controle ostensivo dos trabalhadores, com o objetivo de intensificação do trabalho e o aumento contí­nuo de produtividade, e estudar as consequências para os trabalhadores advindas dessas práticas. Será ainda discutido como o conceito de resiliência vem sendo adotado no contexto organizacional como uma competência a mais que o trabalhador deve ter, e no sentido de não se permitir falhas no sistema. A investigação foca as atividades bancárias e de teleatendimento. A análise será feita a partir de dados de fiscalizações realizadas pela auditoria fiscal do trabalho do extinto Ministério do Trabalho (hoje Ministério da Economia). Serão analisados quatro relatórios de ações fiscais, bem como relatórios de análise de doenças psí­quicas relacionadas ao trabalho. Nesse contexto serão discutidos ainda os limites do poder diretivo que, ao adotar essas práticas como legí­timas e naturais, na busca por aumento de produtividade e lucro, ignoram questões éticas e os riscos gerados para a saúde dos trabalhadores.

For the first time, a liposomal form of a new original drug based on the Siberian musk deer preputial gland extract was obtained and characterized. An effective and scalable method of high-pressure homogenization was used for preparative extraction of liposomes from musk extracts. For the obtained liposomal product, such indicators as the quality of size distribution, homogeneity and the degree of inclusion of biologically active components were characterized using the methods of dynamic light scattering, transmission microscopy, preparative and analytical chromatography and chromatography-mass spectrometry. A homogeneous dispersion of musk liposomes with a uniform size distribution was obtained, with the maximum distribution values being achieved at 50 and 240 nm. The ζ-potential of the obtained nanoparticles of –35...–47 mV confirmed a high physicochemical stability of the developed liposomal dispersion. According to the gel filtration chromatography and mass spectrometry results, the degree of inclusion of the target musk extract components in the liposomes was 55–75% in terms of steroid and total protein values. The obtained quality indicators indicate that the developed liposomal composition of musk deer extracts can be used as a high-effective natural adaptogen.

Research laboratories in various countries are constantly endeavouring to improve the existing and to create new biological objects to simulate various human diseases. Immunodefi cient mice with transplanted human functional cells and tissues, as well as transgenic animals with the relevant human genes integrated in their genome — i. e. humanized mice — are increasingly used as test systems in biomedical studies. Humanized mouse models are constantly being improved to fi nd application in studies investigating human biological reactions and identifying the pathogenetic mechanisms behind a wide range of diseases, or as preclinical tools for medicine testing. In particular, such animals play an increasingly important role both in studies of human-specifi c infectious agents, cancer biology research and in the development of new antitumour agents. In addition, humanized mice are increasingly used as translational models in many areas of clinical research, including transplantology, immunology and oncology. Ultimately, the use of humanized animals can lead to the introduction of a truly personalized medicine into clinical practice. In this review, we discuss modern advances in the creation and use of humanized mice, emphasizing their usefulness for the pathogenesis study, as well as the development of new methods for human cancer treatment.
