Cardiorenal effects of newer antidiabetic agents
Authors: Papazafiropoulou Athanasia K. , Georgopoulos Elias , Antonopoulos Stavros
Published: July 2021

Chronic kidney disease is a major problem of public health and is associated with increased cardiovascular mortality and morbidity. Its treatment includes multifactorial intervention: optimal blood pressure and intensive glycaemic control. There are many studies – clinical and experimental – demonstrating that classic and newer antidiabetic agents delay the progression of diabetic nephropathy. Glucagon-like-peptide-1 (GLP-1) receptor agonists and sodium-glucose co-transporters-2 (SGLT-2) inhibitors have renoprotective action. Furthermore, these antidiabetic agents have beneficial effects to the cardiovascular system, including weight loss and blood pressure reduction. Large, randomized, placebo-controlled outcome trials have showed that SGLT-2 inhibitors and GLP-1 receptor agonists are able to reduce cardiovascular events. Therefore, the present review aims to summarize the existing data regarding the effect of newer antidiabetic agents on kidney function and cardiovascular system.
The impact of parental health status on children’s eating habits and behaviors: A narrative review
Authors: Bogri Maria , Kanellopoulou Aikaterini , Notara Venetia , Panagiotakos Demosthenes
Published: July 2021

Although the problem of childhood obesity has been broadly documented over the last decades and characterized as one of the most significant problems of public health, the percentage of overweight and obese children remains extremely high. It is undeniable that parents contribute significantly in shaping children’s dietary behavior and can be a valuable factor for implementing effective strategies. However the influence of parental health status on children’s eating habits is another aspect that remains almost uninvestigated. The aim of the study is to examine to what extend parental diet-related chronic diseases affect their own but also their children dietary behavior. A literature review was conducted focusing on studies published within the last decade. The majority of studies examined,indicated a moderate to very low adherence to dietary guidelines for a specific disease, as a result children’s dietary behavior is not favorably affected.Therefore we should emphasize on the importance of healthy dietary modeling especially in case of a family history of disease.

Both the innate and adaptive arms of the immune system partake in various steps of atherogenesis. Recent studies have unraveled proatherogenic properties to clonal hematopoiesis of indeterminate potential (CHIP). Krüppel-like factors (KLFs) are transcription factors regulating pathways that confer atheroresistant and anti-inflammatory effects. Pharmaceutical targeting of inflammatory cascades could be beneficial in battling atheromatosis. Statins, aspirin, and other anti-platelet medication have off-target immune-modulatory effects. Canakinumab, a monoclonal antibody targeting IL-1β significantly reduces major adverse cardiovascular events. Nevertheless, according to the CANTOS study this does come with an increased risk of sepsis. As shown in the LoDoCo and COLCOT trials, low-dose colchicine also exerts substantial cardiovascular protection without predisposing to infections. Targeting other pathways has yet to provide an evidence of cardiovascular benefit.
Do platelet mediators and coagulation factors affect the formation of neutrophil extracellular traps?
Authors: Moschonas Iraklis C. , Papadaki Styliani , Sidiropoulou Sofia , Tselepis Alexandros D.
Published: July 2021

Aim: To investigate the effect of factor Xa (FXa), thrombin and platelets, under activation or resting conditions, on neutrophil extracellular traps (NETs) formation (NETosis). Materials and Methods: Neutrophils, isolated from apparently healthy volunteers, were challenged with 25-50 nM FXa, 0.2-8 U/mL thrombin, 5-100 μM adenosine diphosphate (ADP), 0.1-0.5 mM arachidonic acid (AA), 5-15 μg/mL collagen, 100 μM protease-activated receptor (PAR)-4 activating peptide, 10-100 μM PAR-2 activating peptide or 25-100 nM phorbol 12-myristate 13-acetate (PMA). Moreover, neutrophils were challenged with platelet-rich plasma (PRP), activated with ADP (at a concentration of either 20 μM, in an aggregometer, or of 50 μM, in situ). Neutrophils were incubated for 3.5 h at 37οC and 5% CO2 and an immunofluorescence protocol followed, in order to stain neutrophils and NETs for myeloperoxidase and DNA. Finally, NETs and neutrophils were microscopically visualized and the percentage of NET-releasing neutrophils of each of the above experimental conditions was evaluated. Results and Conclusion: Among the agonists studied, only PMA and AA, induced robust NETosis, at a threshold concentration of 25 nM and 0.25 mM, respectively. Furthermore, platelets pre-activated with ADP, but not resting platelets induce the formation of NETs, a phenomenon that is also observed when platelets were activated with ADP in situ, in the presence of neutrophils. The present results provide an additional mechanism through which platelets contribute to various pathophysiological conditions in which NETs are implicated, such as inflammation and thrombosis. The whole spectrum of platelet mediators that are implicated in NETosis needs to be further investigated.

Published: July 2021

Food allergy is a typical immediate-onset allergic disease in which symptoms are provoked by exposure to the sensitized antigens. Although previous reports have shown that omalizumab has helped children with egg or milk allergy achieve oral immunotherapy safely, there is still no established method for induction of remission in adult food allergy. A 51-year-old woman with oral steroid-dependent severe asthma was treated with omalizumab for 6 years. She had shellfish and wheat food allergy and oral allergy syndrome induced by kiwi and other foods associated with latex-fruit syndrome. Since omalizumab treatment, her food allergy symptoms had disappeared. After 7 years of this treatment, disseminated erythema suddenly appeared; omalizumab was discontinued because of suspected drug-induced eruption. After omalizumab interruption, she felt an itching sensation in her throat with worsened asthma control immediately after wheat ingestion. Readministration of omalizumab improved these symptoms. Thus, we raised the possibility that omalizumab not only improved asthma control but also induced pharmacological remission of the patient’s food allergy. Omalizumab may be considered as a treatment option for adult patients with food allergies and severe asthma.
Parasitism and behavioral responses of Acromyrmex coronatus (Fabricius, 1804) and Acromyrmex crassispinus (Forel, 1909) (Hymenoptera: Formicidae) to Myrmosicarius catharinensis Borgmeier, 1928 (Diptera: Phoridae) in Londrina, PR

Leaf-cutting ants of the genus Acromyrmex cause serious damage to cultivated forest areas. Some flies of the family Phoridae are known to parasitize them, and the result of this interaction can provide a promising basis for the management of these ants. This study was developed to record the parasitism and behavioral responses of Acromyrmex spp. leaf-cutting ants to parasitoid phorids in the municipality of Londrina-PR, Brazil. Visual examinations and collections of leaf-cutting ants and associated phorids were carried out between October/2019 and April/2020 in selected anthills and their trails, located on the campus of the State University of Londrina (UEL) and at the Botanical Garden of Londrina. The collected insects were preserved in 70% alcohol, for later identification of the species. The behavioral response of the ants to the parasitoids was recorded individually and collectively, following protocols cited in the literature. The frequencies of the different response behaviors exhibited by the attacked ants were compared using analysis of variance. The leaf-cutting ant species Acromyrmex coronatus and Acromyrmex crassispinus were found at the two evaluated sites. Myrmosicarius catharinensis was the only species of parasitoid phorid found, which attacked both ant species. Although the occurrence of M. catharinensis has been reported in other Brazilian states and its association with A. crassispinus recorded in Buenos Aires, Argentina, this is the first report of the occurrence of the phorid in the state of Paraná with a new association for the species A. coronatus. Under foraging action by the parasitoid, 63.5% of the ants exhibited only one behavioral response, while 36.5% showed two. Accelerated walking, attempting to “bite” the parasitoid, and adopting a ‘C’ posture were the most frequent behavioral responses to avoid parasitism. Ants crowding together around a worker and the presence of “hitchhiker” workers on the transported leaf fragments were the observed changes in collective behavior, the latter being the most frequent. These changes occurred in all observed ant nests and, in two of them, the constancy of alteration in collective behavior was 53%. These results demonstrate the interference caused in nests of Acromyrmex spp. by the occurrence of M. catharinensis, a potential control agent for this pest.

It was aimed to evaluate anti-GnRH vaccine efficiency on productive characteristics, seminal performance, size, and histology of testicles of lambs submitted to immunocastration. Twenty contemporary Texel lambs were evaluated, being 10 animals received two doses of 1 mL of anti-GnRH vaccine and 10 received two doses of 1 mL of saline, with an interval of 30 days. Seminal characteristics, weight and histological cut for the testicles, productive performance, and blood parameters were analyzed. Andrological monitoring was carried out every 30 days. All animals were kept on pasture of Urochloa spp. receiving daily supplementation protein-energetic by 90 days. There was effect of immunocastration on slaughter weight (44.3 vs. 48.3 kg), total gain (9.9 vs. 10.3 kg), daily gain (104.5 vs. 108.9 g/day), and feed conversion (5.83 vs. 5.97) respectively to immunocastrated and intact lambs. There was immunocastration effect on testicle weight (0.09 vs. 0.35 g), motility (4.5 vs. 61.0%), vigor (0.40 vs. 3.00), volume (0.09 vs. 0.74 mL) and swirling (0.20 vs. 2.70) in the third semen collection. Immunocastration through two doses of 1 mL of anti-GnRH vaccine with a 30-day interval between doses, causes infertility in sheep and can be adopted for lambs.

The study aimed to evaluate the in vitro antioxidant action of glycosaminoglycans (GAGs) from the skin of Oreochromis niloticus, and to determine their ideal concentration to supplement the sperm freezing medium of Prochilodus brevis. In experiment 1, the in vitro antioxidant properties of GAGs were verified through the analysis of DPPH, chelating ferrous ability, and total antioxidant capacity. In experiment 2, milt pools were formed, which were frozen in solution supplemented or not with different GAGs concentrations: 0 (control), 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, or 5.0 mg mL-1 (total of 10 treatments). The samples were evaluated for membrane integrity, DNA integrity, sperm morphology, and sperm kinetics. The results of experiment 1 showed that the GAGs exhibited, with the increase of the concentration, significant antioxidant action, for all the evaluated tests, mainly in the chelating ferrous ability. In experiment 2, it was observed that the increase of GAGs concentration decreased kinetic parameters (P < 0.05), however, the control and 0.5 mg mL-1 GAGs concentration showed similar results. For the other parameters (membrane integrity, DNA integrity, and sperm morphology), there was no decrease in results with the increase of GAGs concentration. In conclusion, GAGs extracted from O. niloticus skin have antioxidant action, and the concentration of 0.5 mg mL-1 was the most adequate to supplement the P. brevis sperm-freezing medium.

The aim of this study was to evaluate the chronic salinity tolerance of Carassius auratus and the effects on blood parameters, gill morphology, and survival. In the first test, nine different concentrations (0.0, 0.5, 1.0, 2.5, 5.0, 10, 15, 20, and 25 g L-1) of NaCl were used with nine repetitions for 96 h. The survival of fish subjected to 15 g L-1 NaCl was 4 h, and 5 min at a concentration of 25 g L-1. The mortality of fish with 15 g L-1 NaCl was 100%. Morphological analyses of the gills showed hyperplasia of the coated cells in the interlamellar space and hypersecretion of mucus in fish exposed to 10 g L-1 of NaCl. At concentrations of 20 and 25 g L-1, necrosis of the support collagen caused the cells to detach from the lamellar structure mucosa. In the chronic test, two concentrations were used, with four replications containing nine fish in each aquarium for a period of 21 days. Blood samples and gills from the fish were collected, and it was observed that the fish showed a decrease in the concentration of bicarbonate (NaHCO3) in the blood, indicating hypernatremia. Acute exposure of C. auratus to sodium chloride (NaCl) should be at a maximum of 10 g L-1 of NaCl, after which level there would be a loss in animal performance and/or mortality. Chronic exposure to 5 g L-1 of NaCl promotes acidemia, ionic imbalance, and pathological changes in the gills; therefore, it is not recommended.

A Review on the New Normal, Employee Wellbeing and the Role of HRM: A Tale of HR among the New Normal for the Employee Wellbeing
Authors: Yvonne Kiconco , Jiang ShiMei
Published: July 2021

The sudden change in scenarios due to the COVID-19 pandemic has not only affected people’s financial situations but also their health and wellbeing. Psychological, physical discomfort along with on and off work schedules have led to stress for both the employer and employee. Gearing pressure of competition to survive in the dying economy has led to a path for the ‘New Normal’ where the current situation has been accepted as Normal with new adaptations. Employees, risking their lives and leaving the so-called comfort of their homes have had to step out to join the office while others have turned their homes into offices so as to work from home. They are at high risk of infection and stressed with the changed working scenario. The most challenging phase for the employers is the well-being of their employees for the continuous and timely work progress. The Role of HR has become the most crucial factor during this pandemic. Dealing with the employees and getting the work done with the limited resources in the crisis is the most challenging task. The present paper studies the three terms- 'New Normal', 'Employee Wellbeing' and 'Role of HR' within linked perspective and provides insight based on the various researches done in this field. It has been found that employee well-being is a well-talked topic and it has been a great concern for all the HR executives for a long time. Well- being of the employee ensures mutual gain for the employee and the organization both.
Volatility Analysis and Visualization of Climate Data Based on Wavelets
Authors: Liu Meili , Wang Liwei , Lee Chun-Te , Lin Jeng-Eng
Published: July 2021

In this article, we analyze the real meteorological data recorded by Wenzhou Meteorological Bureau from 1951 to 1997. The data has not been used elsewhere and is available at Meteorological Station Wenzhou (ID: CHM00058659) at https://geographic.org/global_weather/china. We perform the time series volatility analysis including ARMA, ARIMA, ARCH-LM, PARCH, SARMA and Morlet wavelet analysis and use the Mann-Kendall (M-K) test to analyze both the trend and mutation defined by statistics sequence. In addition, a Morete wavelet time-frequency model is established to show that both the precipitation and temperature have a very important 12-month cycle and the precipitation is also very unstable. We then employ the STL, coif1 decompositions and NAR model to capture both the volatility and Heteroscedasticity in the data. In addition, the performance of the fitted model has been proven to be satisfactory on actual climate data with the small Mean Square Error (MSE), Root-Mean-Squarred Error (RMSE), and coefficient of determination. Finally, monthly average temperature is added as an exogenous (covariate) variable and a nonlinear autoregressive exogenous model is employed to improve the performance of the model. Our results show that the performance of NARX model is more accurate and stable with better mean square error.

The promoter is a part of the gene that functions in carrying out the gene expression, and its work activity becomes a matter of concern to ensure that expression works effectively. MeEF1A6 (Manihot esculenta Elongation Factor 1 Alfa - 6) is a promoter derived from cassava plants (Manihot esculenta). In previous studies, the MeEF1A6 promoter was successfully isolated, introduced, and characterized into the pBI121 plasmid, replacing the CaMV35S promoter. This study aims to analyze the activity of MeEF1A6 promoters in-vivo and in-vitro by using transient and transgenic techniques in tobacco plants. The pBI121 plasmid containing the MeEF1A6 promoter was introduced into Agrobacterium tumefaciens strain AGL1 and LBA4404. The promoter's work was then analyzed by the result of introducing it into the tobacco plant using the transient and stable transformation. The whole part of explants was used for transient study and tested in a minimum of two biological replicates. Sixty sheets of explant leaves that have been cut were used for stable transformation. The promoter work analysis was carried out with the GUS gene expression that integrated with the promoter with histochemical GUS assay. The transient produced a blue color in the roots, stems, and leaves on the whole repetition. The transverse incision in the stem shows the blue color on the epidermis and procambium tissue. Stable transformation using AGL1 as vector produced 43 shoots from 40 calli. A total of 43 shoots were selected with antibiotics and produced 27 plantlets that were successfully grown. Some plantlets are then reacted with x-gluc as histochemical GUS assay substrat and produced a blue color in the explants, indicating that the MeEF1A6 promoter has been successfully introduced. The results indicate that the MeEF1A6 promoter could work on plant tissue in roots, stems, leaves, and tissues that connect meristems such as procambium in tobacco plants. This reinforces the suspicion that the MeEF1A6 promoter performs work constitutionally as a constitutive promoter.

Pliek u is an Acehnese traditional condiment made from fermented coconut (Cocos nucifera) endosperm. The traditional pliek u fermentation process typically involves a diverse bacterial community. This research aimed to discover the physiological profile of the bacterial community diversity in pliek u fermentation. BIOLOGTM EcoPlates was used to obtain the physiological functions of the bacterial community during the pliek u fermentation process. The bacteria were then isolated from EcoPlate substrate to determine the predominant microorganism. Results from the analysis showed that the value of the Average Well Colour Development (AWCD) increased during the EcoPlates incubation period. The AWCD values in sample IV were higher than the AWCD values in samples I, II, and III. PCA analysis showed that the use of EcoPlate substrate by the bacterial community at the beginning of the fermentation was correlated with the substrate groups of carbohydrate and polymer, and with the substrate groups of carbohydrate and the amino acid at the end of the fermentation. The phylogenetic analysis showed that EC1 had a close relation with Pseudomonas azotoformans strain NBRC, while EC3 had a close relation with Psedomonas lundensis strain ATCC 49968. In conclusion, there were changes in the use of EcoPlate substrate and the activities of the bacterial community during the pliek u fermentation process.

To evaluate the pulmonary toxicity of Korean chrysotile (KC), 1 or 2 mg of KC (low- and high-concentration groups, respectively) was instilled in the lungs of Sprague-Dawley rats by a single intratracheal instillation. The lungs were examined using a light microscope at several time points (5 days, 5 weeks, and 10 weeks). Up to 10 weeks after KC instillation, differences were observed in the pathological reactions and ultimately in lung recovery between the two groups. At 5 days after KC instillation, lung weight increased and severe bronchiolitis obliterans developed in proportion to the KC concentration administered. From 5 to 10 weeks after KC administration, the lung weight of the low-concentration group increased and bronchiolitis obliterans worsened. In the high-concentration group, the lung weight and the severity of bronchiolitis obliterans at 10 weeks after administration of KC declined compared to those at 5 weeks. In conclusion, the effects of KC on lung tissue were initially found to be more influenced by the amount of fiber, but over time, the effects were influenced by the residual fibrous material in the lung tissue and its biodurability.

Culture-Specific Information Encoded in Lacunae: The Author’s and Translators’ Strategies of Representation
Authors: Slavova Liudmyla , Borysenko Natalia
Published: July 2021

The present study examines the representation of Ukrainian culture-specific information in Marina Lewycka’s novel A Short History of Tractors in Ukrainian. Such information is encoded in lacunae and the author’s or translator’s task is to decode it using relevant translation strategies. The latter ones have been identified: 1) the strategy of domestication (equivalent or near equivalent translation); 2) the combination of domestication and foreignization (transliteration together with a near equivalent and descriptive translation, calque translation accompanied by descriptive translation); and 3) the strategy of foreignization (borrowing, transliteration alone or combined with calque translation). Graphic means such as inverted commas and italics are used to mark information as culture-specific for the reader. Ukrainian and Russian translations of the novel demonstrate that lacunae are rendered mostly with the help of the corresponding Ukrainian and Russian lexemes. It has been revealed that archaic forms can be substituted by modern ones, and both native and borrowed elements are employed. This paper also demonstrates that the procedures and means used in rendering Ukrainian culture-specific information in the source English and target Ukrainian and Russian texts aim at finding balance between the strategies of domestication and foreignization used in the presentation of culture-specific information.
Конвербы в русском и литовском языках

Published: July 2021

В работе представлен обзор особенностей русских и литовских конвербов в сопоставительном аспекте. Обобщаются существующие положения относительно происхождения, современного употребления форм и синтаксических функций конвербов, конвербы сопоставляются с точки зрения маркирования глагольных категорий и их отношения к субъектудействия. Отмечается, что основной семантической особенностью конвербов является сопряженность выражаемого ими действия с действием, выраженным опорным глаголом, при которой конвербы локализуют события на временной оси в контексте дейктического значения опорного глагола. С этой точки зрения конвербы представляют собой тип зависимого таксиса, значения которого (одновременность/предшествование) в русском и литовском языках морфологически реализуются по-разному: в русском – за счет противопоставления, осуществляемого показателями вида, в литовском – за счет противопоставления, осуществляемого показателями времени. На основании анализа русских и литовских корпус-ных материалов (НКРЯ и DLKT) устанавливается, что соответствия между данными типами корреляций (деепричастием НСВ – пусдаливисом (полупричастием) или падаливисом настоящего времени, деепричастием СВ – действительным причастием прошедшего времени или падаливисом прошедшего времени) присутствуют в большинстве контекстов при значениях временного отношения, однако в контекстах логического отношения проявляются закономерности другого характера.

Introduction: Pyogenic liver abscess (PLA) is a serious infectious disease of the liver. Pyogenic liver abscess caused by Fusobacterium nucleatum is extremely rare. Here we report the first case of liver abscess caused by F. nucleatum in China. Case Presentation: The case was a 34-year-old female patient admitted to the hospital due to high fever. The diagnosis of liver abscess was confirmed by imaging studies and liver puncture. We finally confirmed the pathogen as F. nucleatum by next-generation sequencing (NGS). After the targeted anti-infective treatment, the patient recovered and discharged. Conclusions: As a new microbial detection method, NGS can still help in clinical practice. In addition, to improve the positive rate of anaerobic bacteria culture, we should pay attention to avoid contact with air in the process of specimen collection when the pathogenic bacteria are suspected to be anaerobic bacteria.
Technologies of Reproduction: Race, Disability, and Neoliberal Eugenics
Authors: Valentine Desiree ,   Philosophy Documentation Center
Published: July 2021

When considering the relation between race, disability, and reproduction, race and disability tend to figure as outcomes of reproduction. It is assumed that one births a child with a certain race and ability status as a function of biological and genetic processes. This paper shifts such analyses of race and disability in the context of contemporary reproduction to examine how race and disability are not only produced but are productive. Building on recent work describing race as a technology emergent in certain sociopolitical contexts and used to develop and maintain certain ways of life, intimate and collective relations, and political orders, this essay examines the possibilities for understanding disability as a technology. It argues that race and disability function as technologies in contemporary reproductive practices through the naturalization of choice, the normative production of ‘risk,’ and the making and unmaking of kinship.
Proposal of new genera and species of the subfamily Diosaccinae (Copepoda: Harpacticoida: Miraciidae)

Published: July 2021

Representatives of several genera of the family Miraciidae (Copepoda: Harpacticoida) were found in sediment samples taken in the year 2019 from a coastal system in north-western Mexico. The subfamily Diosaccinae (Miraciidae) was by far the most diverse taxon followed by the subfamily Stenheliinae (Miraciidae). Here we report on a new miraciid species, Typhlamphiascus medici sp. nov., and provide a new amended diagnosis for Typhlamphiascus Lang, 1944 along with a key to its species. Additionally, Typhlamphiascus lamellifer lamellifer (Sars, 1911) and T. l. capensis Kunz, 1975 are considered as distinct species and the latter is given full species rank. Upon preliminary inspection, another diosaccin species was thought to be a derived form of Bulbamphiascus Lang, 1944. This promoted us to perform a more in-depth phylogenetic analysis. Our results showed that the new presumed derived form of Bulbamphiascus represents a new genus, Spinodiosaccus gen. nov. and that the genus Bulbamphiascus, which we propose a new amended diagnosis for, could be split into different genera. Also, the possible relationships amongst the different diosaccin clades found during our analyses are commented. We give a brief ecological analysis on the distribution of T. medici sp. nov. and S. primus gen. et sp. nov. in the Urías system.
