Published: February 2021

Present issue proposes a solution to the problem of the waste oils with different composition recycling into esters of fatty acids and low-molecular alcohols by using flexible type technology. Waste oils differ in the composition of hydrocarbon radicals of the vegetable oils triglycerides and in the content of the free fatty acids impurities. For waste oils processing it is advisable to use technology options that differ in combinations of basic technological operations. An algorithm is proposed for selecting the main technological operations and their combinations for inclusion in the technology process, taking into account the composition of the recycling raw materials and the type of product obtained. The flexibility of the technology is provided by using different combinations of reactor blocks, each of which is designed to perform one of the provided technological operations. The developed flexible type technology was tested in the recycling of experimental batch of the low-eruption rapeseed oil waste.

The paper explores the germination of seeds, yields and an tioxidant properties of microgreens of different varieties and varieties of Petroselinumcrispum (Mill.) Nym. in controlled microclimatic conditions. The most active germination of seeds was observed in the interval of 7-11 days after sowing. The total increase in microgreens in height almost stops after 14 days of germination in the dark. Thus, growing products by germination in the dark is advisable longer than this period to get microgreens promising leafy varieties of parsley. A significant increase in total antioxidant activity in seed germination has been established – 2.7-5.6 times for different varieties. Parsley Petroselinumcrispum (Mill.) Nym. – a herbaceous plant used in many kitchens of the world as spicy and for the preparation of side dishes. The main flavor compounds of parsley are 1.3.8-n-metatrien, apiol, myristicin, and tetramethoxyallbenzene, of which apiol and mydisticin are “toxic in large doses”. Green, herbaceous and fruit notes in parsley are determined by the hex-3-enil, (Z)-hex-3-enol and (Z)-hex-3-enylacerate. It is proposed to use parsley as a component of functional products in the treatment of cancer. Growing parsley microgreens is advisable due to the high antioxidant and other beneficial properties. Despite the slow and time-stretched germination of seeds, within 2 weeks of cultivation formed a fairly high vegetative mass, which can be used for food and medicinal purposes, for example, as a product of functional nutrition. It is possible to grow products in the dark without the use of artificial light sources. The highest yield is provided by leafy varieties of parsley compared to root varieties.

Published: February 2021

In the example of complex grassmannians, we demonstrate various techniques available for computing genus-0 K-theoretic GW-invariants of flag manifolds and more general quiver varieties. In particular, we address explicit reconstruction of all such invariants using finite-difference operators, the role of the q-hypergeometric series arising in the context of quasimap compactifications of spaces of rational curves in such varieties, the theory of twisted GW-invariants including level structures, as well as the Jackson-type integrals playing the role of equivariant K-theoretic mirrors.
Temperature in Solar Sources of 3He-rich Solar Energetic Particles and Relation to Ion Abundances

Published: February 2021

3He-rich solar energetic particles (SEPs) are believed to be accelerated in solar flares or jets by a mechanism that depends on the ion charge-to-mass (Q/M) ratio. It implies that the flare plasma characteristics (e.g., temperature) may be effective in determining the elemental abundances of 3He-rich SEPs. This study examines the relation between the suprathermal (≲0.2 MeV nucleon−1) abundances of the He–Fe ions measured on the Advanced Composition Explorer and temperature in the solar sources for 24 3He-rich SEP events in the period 2010–2015. The differential emission measure technique is applied to derive the temperature of the source regions from the extreme ultraviolet imaging observations on the Solar Dynamics Observatory. The obtained temperature distribution peaks at 2.0–2.5 MK that is surprisingly consistent with earlier findings based on in situ elemental abundance or charge state measurements. We have found a significant anticorrelation between 3He/4He ratio and solar source temperature with a coefficient −0.6. It is most likely caused by non-charge-stripping processes, as both isotopes would be fully ionized in the inferred temperature range. This study shows that the elemental ratios 4He/O, N/O, Ne/O, Si/O, S/O, Ca/O, Fe/O generally behave with temperature as expected from abundance enhancement calculations at ionization equilibrium. The C and Mg, the two species with small changes in the Q/M ratio in the obtained temperature range, show no such behavior with temperature and could be influenced by similar processes as for the 3He/4He ratio.

We present a study of molecular outflows using six molecular lines (including 12CO/13CO/C18O/HCO+ (J = 1−0) and CS/SiO (J = 2−1)) toward nine nearby high-mass star-forming regions with accurate known distances. This work is based on the high-sensitivity observations obtained with the 14 m millimeter telescope of the Purple Mountain Observatory in Delingha. The detection rate of outflows (including 12CO, 13CO, HCO+, and CS) is 100%. However, the emission of SiO was not detected for all sources. The full line widths (ΔV) at 3σ above the baseline of these molecular lines have the relationship

. 12CO and HCO+ can be used to trace relatively high-velocity outflows, while 13CO and CS can be employed to trace relatively low-velocity outflows. The dynamical timescales of the 13CO and CS outflows are longer than those of the 12CO and HCO+ outflows. The mechanical luminosities, masses, mass-loss rates and forces of all outflows (including 12CO, 13CO, HCO+, and CS) are correlated with the bolometric luminosities of their central IRAS sources.

Published: February 2021

Clinopodium vulgare L. (Lamiaceae) was used in the traditional Bulgarian medicine for treatment of wounds, diabetes and gastric ulcers. The aim of the present study was to evaluate the antioxidant capacity of the extract (CVE) and fractions from C. vulgare (CV) using DPPH, ABTS and FRAP methods. Enzyme inhibitory activity against acetylcholinesterase, α-glucosidase and α-amylase was also investigated. Rosmarinic acid was used as a positive control. The fraction CV3 demonstrated the highest radical scavenging activity with IC50 values of 0.02 mg/ml (DPPH) and 0.0002 mg/ml (ABTS), as well as the strongest ferric reducing potential (FRAP) of 0.89 mM TE/mg dw. The crude aqueous-methanol extract of C. vulgare also showed high activity with IC50 values of 0.05 mg/ml (DPPH), 0.04 mg/ml (ABTS) and 0.89 mM TE/mg dw (FRAP). Moreover, CV3 demonstrated moderate α-glucosidase and α-amylase inhibitory potential.

Ornamentula
Kisielewski, 1991 is a monospecific genus in Order Chaetonotida. The sole species, O. paraensis Kisielewsk, 1991, is a semiplanktonic gastrotrich found in a single pond in the Amazon region of Brazil. Herein we describe a new species of the genus Ornamentula, collected in a small urban lagoon in the Atlantic Forest of southeast Brazil. Ornamentula miyazakiisp. nov. resembles O. paraensis, but it shows differences in the ornamented trunk scales and spinal spines distribution, sufficient to proposte it as it’s a new species.
La formation à l’épreuve de la psychanalyse
Authors: Assoun Paul-Laurent
Published: February 2021

Le terme de formation semble lié à un discours technique et pédagogique, et c’est cela que la psychanalyse met radicalement à l’épreuve. Aussi est-il essentiel de reconsidérer, comme à neuf, à quoi l’on forme quand on « forme » un psychanalyste. Il est essentiel de redécouvrir à cette fin le concept de Bildung , en sa connotation éminemment culturelle. Freud invente l’analyste, en son originalité absolue, par son slogan Psycha. Fara da se , en sorte qu’elle ne craint rien de l’Université et y a sa place légitime… d’autant plus qu’elle pourrait s’en passer. En sorte qu’il n’hérite de la psychothérapie qu’en la dé- formant suffisamment pour y affronter le réel inconscient. Il faut alors, pour penser l’ Ausbildung , c’est-à-dire la formation au sens « professionnel », démarquer la question du savoir de celle de l’acquisition des connaissances – problème auquel s’est confronté l’Institut psychanalytique de Berlin il y a juste un siècle. Lacan, dont on sait les démêlés institutionnels sur la question de la formation, enfonce le clou freudien en faisant de l’analyste même un symptôme, une formation inconsciente. Il y aurait alors à redécouvrir l’idée de « mouvement psychanalytique » comme acte culturel autant que clinique. Ledit analyste étant le mieux placé pour adresser à la Kultur le réel de son malaise, attesté par le symptôme. Métier de l’impossible, selon l’expression freudienne, à ce titre irremplaçable.
La formation de l’analyste
Authors: Lippi Silvia
Published: February 2021

Nous allons analyser la place de la théorie en psychanalyse, théorie qui constitue un des trépieds de la formation du psychanalyste aux yeux de Freud, mais qui a aussi une place active à l’intérieur de la cure analytique. La place de théorie en psychanalyse, en particulier dans son rapport avec sa pratique, se distingue de l’usage de la théorie dans la médecine et dans la psychologie, notamment car, dans la discipline inventée par Freud, la théorie est distincte du savoir.
L’exigence éthique dans l’acte analytique
Authors: Benabdallah Fouzia
Published: February 2021

Cet article tente d’examiner la question éthique qui prenait et prend encore une place très particulière dans la définition de l’acte analytique, depuis le questionnement éthique engagé par Freud vis-à-vis de la responsabilité de l’analyste et de la manière avec laquelle il répond au transfert de l’analysant. Pour aborder cette question, nous allons mettre en exergue la notion de désir de l’analyste et son rapport à la question éthique.

De larges extraits de la conférence de F. Jullien restituent ici la vivacité de sa pensée dont il nous a fait bénéficier en direct le 14 mars 2020. À partir de son expérience de l’altérité radicale du chinois pour un philosophe européen il évoque là ce que lui a apporté la capacité de sortir de sa pensée. Ce qui le conduit vers ses thèmes de prédilection depuis cette expérience d’immersion en une pensée intraduisible : vivre ou exister, l’inouï et la dé-coïncidence, l’accès à l’inouï par la poésie, l’inouï de l’autre… Une démarche forte qui ne peut laisser indifférent aucun Gestalt-thérapeute.

Stability analysis and optimal control of production-limiting disease in farm with two vaccines
Authors: Liu Yue , Lo Wing-Cheong
Published: February 2021

The transmission of production-limiting disease in farm, such as Neosporosis and Johne's disease, has brought a huge loss worldwide due to reproductive failure. This paper aims to provide a modeling framework for controlling the disease and investigating the spread dynamics of Neospora caninum-infected dairy as a case study. In particular, a dynamic model for production-limiting disease transmission in the farm is proposed. It incorporates the vertical and horizontal transmission routes and two vaccines. The threshold parameter, basic reproduction number \begin{document}$ \mathcal{R}_0 $\end{document}, is derived and qualitatively used to explore the stability of the equilibria. Global stability of the disease-free and endemic equilibria is investigated using the comparison theorem or geometric approach. On the case study of Neospora caninum-infected dairy in Switzerland, sensitivity analysis of all involved parameters with respect to the basic reproduction number \begin{document}$ \mathcal{R}_0 $\end{document} has been performed. Through Pontryagin's maximum principle, the optimal control problem is discussed to determine the optimal vaccination coverage rate while minimizing the number of infected individuals and control cost at the same time. Moreover, numerical simulations are performed to support the analytical findings. The present study provides useful information on the understanding of production-limiting disease prevention on a farm.
Evaluating vaccination effectiveness of group-specific fractional-dose strategies
Authors: Chen Zhimin , Liu Kaihui , Liu Xiuxiang
Published: February 2021

In this paper, we formulate a multi-group SIR epidemic model with the consideration of proportionate mixing patterns between groups and group-specific fractional-dose vaccination to evaluate the effects of fractionated dosing strategies on disease control and prevention in a heterogeneously mixing population. The basic reproduction number \begin{document}$ \mathscr{R}_0 $\end{document}, the final size of the epidemic, and the infection attack rate are used as three measures of population-level implications of fractionated dosing programs. Theoretically, we identify the basic reproduction number, \begin{document}$ \mathscr{R}_0 $\end{document}, establish the existence and uniqueness of the final size and the final size relation with \begin{document}$ \mathscr{R}_0 $\end{document}, and obtain explicit calculation expressions of the infection attack rate for each group and the whole population. Furthermore, the simulation results suggest that dose fractionation policies take positive effects in lowering the \begin{document}$ \mathscr{R}_0 $\end{document}, decreasing the final size and reducing the infection attack rate only when the fractional-dose influenza vaccine efficacy is high enough rather than just similar to standard-dose. We find evidences that fractional-dose vaccination in response to influenza vaccine shortages take negative community-level effects. Our results indicate that the role of fractional dose vaccines should not be overestimated even though fractional dosing strategies could extend the vaccine coverage.
Limited-angle CT reconstruction with generalized shrinkage operators as regularizers
Authors: Deng Xiaojuan , Zhao Xing , Li Mengfei , Li Hongwei
Published: February 2021

Limited-angle reconstruction is a very important but challenging problem in the field of computed tomography (CT) which has been extensively studied for many years. However, some difficulties still remain. Based on the theory of visible and invisible boundary developed by Quinto et.al, we propose a reconstruction model for limited-angle CT, which encodes the visible edges as priors to recover the invisible ones. The new model utilizes generalized shrinkage operators as regularizers to perform edge-preserving smoothing such that the visible edges are employed as anchors to recover piecewise-constant or piecewise-smooth reconstructions, while noises and artifacts are suppressed or removed. This work extends our previous research on limited-angle reconstruction which employs gradient \begin{document}$ \ell_0 $\end{document} and \begin{document}$ \ell_1 $\end{document} norm regularizers. The effectiveness of the proposed model and its corresponding solving algorithm shall be verified by numerical experiments with simulated data as well as real data.

Effects of Using Digital Tools on the Process of Memorization
Authors: Hamzi Amine , Echantoufi Noureddine , Khouna Jalal , Ajana Lotfi
Published: February 2021

Recent studies show that the effect of digital tools have a direct impact on atten-tion, motivation, autonomy and academic success. In Morocco, considering the extent to which students use digital tools, precisely scientific students, and be-cause of the essence of memory to all learning, this article is part of the overall framework of a study that attempts to find the link between the use of digital tools and the process of memorization. The factors that can influence the memorization process are multiple and diverse: biological, psychological, and sociological. These factors are unquantifiable in most cases, where it is difficult to determine with certainty their degree of impact, or to experimentally show the nature of their influence on the memory process that constitutes the most important function of the brain being the most complex organ of the human being. Therefore, in this ar-ticle, we will only stick to the duration of use of digital tools as an evaluable pa-rameter, and we will try to determine the link between this duration and the mem-orization process in order to determine the conditions for healthy and efficient us-age
Education Between GovTech and Civic Tech
Authors: Yoshida Masami , Thammetar Thapanee
Published: February 2021

In the recent movement towards smart societies, smart governments supported by GovTech and smart cities developed through Civic Tech have become known as dominant structures enabled by information and communications technology. Since GovTech and Civic Tech share the goal of giving citizens better and safer lives through their engagement with government and technology, the development of online public services is characterized by the use of collaborative production methods involving various stakeholders and players. Open data, collaboration, and systematic teamwork are key to understanding this production of heterarchical structures. This study reviews previous cases of collaboration between GovTech and Civic Tech, identifies the dominant mechanisms of the smart society, and summarizes existing pedagogical and industrial theoretical systems, mindsets, and skillsets with the aim of developing content for a university course. Double loop learning, design thinking, the Agile methodology, and the lean principle are identified as theoretical systems. Our findings are arranged so that they can be applied in the content of a university-level educational technology course, which we designed to develop students’ transformative competencies to enable them to become active citizens. In addition, we compared the processes involved in observed theoretical systems and conventional pedagogical theories to clarify the differences in their mechanisms. We conclude with a discussion of the need to recognize frameworks of different paradigms to prepare students for transformative social activities.

Authors: Cao Yusong
Published: February 2021

With the advent of the big data era, significant changes have taken place in every aspect of education. To effectively evaluate the academic performance of college students, this paper firstly establishes a scientific evaluation index system for student portrait. Taking the course Object-Oriented Programming as an example, the authors collected various data on the academic performance of college students. The collected data were normalized, and the weight of each evaluation index was determined through analytic hierarchy process (AHP). Next, a fuzzy evaluation model was constructed based on big data, and used to assess each dimension of college students’ academic performance. The evaluation reveals the problems of college students in learning and practice, and helps to generate the portrait of each student. The research results promote the realization of personalized education.

Published: February 2021

This paper is exploring on maneuver to improve research instrument reliability in scientific research related to Educational Technology by analyzing the traditional Cronbach’s alpha reliability using SPSS software and the newer statistical tool, AMOS using Construct Reliability (CR) approach. Two sets of data were used as sample to perform the comparison. The first set of data is from a research involving Technology Enhanced Learning Environment. The second data are sampled from research in digital competency. Finding from this paper concluded that, conventional approach of using Cronbach’s alpha have lower reliability than the newer approach of using CR. Using Cronbach’s alpha show tendency toward measuring consistency instead of reliability. CR offer better definition of reliability and give a robust measurement of reliability in research. This paper had shed light into offering alternative approach to the commonly and widely uses of research reliability especially when it involves questionnaire as instrument.
Second-hand shoe circulations in Tunis
Authors: Grüneisl Katharina
Published: February 2021

Research on the second-hand clothes trade has focused on global value chains and transnational circulations from the Global North to the Global South. This article instead investigates the circulation of a ubiquitous and highly popular second-hand commodity, namely shoes, in the Tunisian capital city Tunis. The second-hand materials – referred to as “fripe” in Tunisia – that arrive in the Tunis cargo port have been donated or discarded in their countries of origin and their commodity value is thus uncertain. In addition, second-hand shoes are officially banned from sale on the Tunisian market. In order to explain how fripe shoes are nevertheless transferred into new commodity situations in Tunis, this article hones in on processes of valuation at the urban scale. Three locations that feature prominently in the urban trajectory of second-hand shoes – a sorting factory, the wholesale quarter, and a specialised market street – are examined as distinct sites for valuation that enable the renewed circulation of fripe shoes in the city. Investigating valuation and circulation with an explicit focus on urban space demonstrates how such processes not only transform fripe objects in circulation, but are also constitutive of socio-spatial relations: At times, valuation becomes manifest in urban form, or situated urban change; At other times, fripe shoe circulations generate linkages and interdependencies that tie seemingly bounded sites of valuation to diverse actors and spaces across the city. As inherently contested commodity form, second-hand shoes thus provide insight into the complex social and political negotiations that define commodity circulation as both contingent and productive urban process.

Notre étude des représentations médiatiques des transidentités est centrée sur la télévision, en raison de la richesse de ses différentes formes de création et de diffusion (actualités, reportages, documentaires, débats, divertissements, fictions et cinéma). Elle s’appuie sur cinq années d’observation participative du terrain transidentitaire français (associations et collectifs transidentitaires, personnes transgenres et transsexes) et sur un corpus de plus de huit cents documents audiovisuels, constitué sur les bases archives de l’Institut National de l’Audiovisuel. Nous nous intéressons aux modélisations sociales et culturelles, causes et conséquences du processus de médiatisation. L’analyse des glissements successifs du lexique médiatique du fait-divers au fait de société, jusqu’à la notion de l’égalité des droits permet de décrire et d’étudier les liens qu’entretiennent des représentations sociales et des représentations médiatiques consubstantielles. Les logiques de production, les structures de représentation des périodes déterminées éclairent sur les dynamiques sociales en action et en interaction.

Du fait linguistique au(x) genre(s) : oralité et scripturalité à l’époque classique
Authors: Goux Mathieu
Published: February 2021

Dans cet article, nous étudions les relations entre les genres textuels et l’emploi du pronom relatif lequel à la fonction sujet au long de la période classique. Nous montrons que l’emploi de ce pronom relatif s’explique, en addition de divers phénomènes linguistiques, par une opposition entre les contextes de production des discours. Nous avons en ce sens distingué les genres dits « écrits » et destinés à une lecture silencieuse, tels les romans ou les essais, et les genres oralisables, comme les pièces de théâtre, les correspondances ou les oraisons. Notre analyse, fondée sur les récentes études de la grammaire des genres, nous permet dès lors d’éclairer certains aspects de l’emploi de ce pronom relatif atypique au cours du XVIIe siècle.
Montaigne : un cas intertextuel ?
Authors: O’Brien John
Published: February 2021

À partir d’exemples pris dans les guerres de religion et le scepticisme, l’intertextualité montaignienne est pensée non comme une concurrence entre elle et l’auteur dont le prix serait la célèbre « mort de l’auteur », mais comme une collaboration entre l’auteur et le lecteur au profit de la spécificité historique des Essais. Sont ainsi mis en valeur les Essais comme fruit d’une activité qui met l’accent sur la transformation des données de l’enquête menée par la skepsis.

Technological Innovations Through Digital Service Design in Hospital Districts
Authors: Ryynänen Sanna , Uusisalmi Riitta
Published: February 2021

The aim of the study is to describe and increase understanding about digital service design in creating technological innovations in Finnish hospital districts. The data was collected via an open questionnaire during March-August 2019 and analyzed using a combined thematic and narrative analysis. Three distinct themes arose from the research narratives: cooperation, development, and cost. First, the importance of cooperation in the early stages of the service design process, when new technological innovation ideas are developed, was emphasized. Second, the possibilities of digitalization and need for new innovations were taken into account in the development theme. Third, costs define the utilization of an innovation and guide its initial development. If savings and costs are in balance, technological innovations will move forward. Moreover, the findings show that technological innovations in hospital districts progress in a certain pattern, and the utilization of innovations come from the need and pressure to evolve.

Discovery of digital innovations is a key organizational capability for sustaining competitive advantage. Despite its importance, discovery of digital innovations is still ill understood. In this paper, the authors seek to provide a theory-based practice for digital innovation discovery. To meet this objective, they source the theories of knowledge and knowledge combination. Data for this case study were collected through semi-structured interviews and a quantitative questionnaire from three pension insurance companies. The data were analyzed by using principal component analysis and by constructing biplots based of the results. Two significant dimensions in the digitalization needs that guide knowledge synthesis were recognized: the importance of adopting the enabler and the volume of resources needed to adopt the enabler. A closer look at the enablers revealed that the most business-critical current digital business enablers for the pension insurance industry are business process automation, online services, and big data.

This cross-secctional study investigated the role of resilience on motivation among athletics and swimming parathletes. The subjects were 64 male (n=41) and female (n=23) parathletes from North and Northeast regions of Brazil. The parathletes were practitioners of athletics (69.5%) and swimming (30.5%), with mean age of 28.42±11.32 years. The instruments were the Sport Motivation Scale-II and Connor-Davidson Resilience Scale. Data analysis was conducted thorugh Kolmogorov Smirnov, Spearman correlation and Path Analysis (p<0.05). The results showed that resilience showed significant correlation (p<0.05) with all controlled and autonomous regulations: external (r=0.29), introjected (r=0.40), identified (r=0.29), integrated (r=0.26) and intrinsic (r=0.42). Path Analysis revealed that that resilience showed a significant (p 0.05) and effect on intrinsic, introjected and external regulations, explaining 16%, 11% and 11% of the variance of the variables, respectively. It should be noted that resilience had a moderate and positive effect on intrinsic (β=0.40), introjected (β=0.33) and external (β=0.33) regulations. It was concluded that in the context of the paralympic athletics and swimming, resilience seems to be an intervening factor on both autonomous and controlled motivation.

Published: February 2021

O objetivo deste estudo foi identificar, na opinião de jogadoras de handebol, os métodos de ensino preferidos e as transferências entre os conceitos enfatizados em cada método e o jogo formal. Foram entrevistadas 17 jogadoras de handebol da categoria adulta de uma equipe municipal do Estado de São Paulo. Seus depoimentos foram analisados a partir do método do Discurso do Sujeito Coletivo. Os resultados mostraram que as jogadoras apresentam preferência por métodos de ensino ativo (como o situacional e o global-funcional), principalmente pelas questões que envolvem a complexidade do contexto do jogo. Em relação à transferência entre os métodos de ensino ativos e o jogo as jogadoras destacaram a demanda psicológica, as questões técnico-táticas, as semelhanças com o contexto do jogo e a necessidade de ajustar os comportamentos às demandas do jogo.  Conclui-se que as jogadoras preferem treinamentos atrelados à dinâmica do jogo, com oposição, privilegiando situações que provoquem questionamentos sobre o jogo.

The reptile MHC class I (MCH-I) and MHC class II proteins are the key molecules in the immune system; however, their structure has not been investigated. The crystal structure of green anole lizard peptide–MHC-I–β2m (pMHC-I or pAnca-UA*0101) was determined in the current study. Subsequently, the features of pAnca-UA*0101 were analyzed and compared with the characteristics of pMHC-I of four classes of vertebrates. The amino acid sequence identities between Anca-UA*0101 and MHC-I from other species are <50%; however, the differences between the species were reflected in the topological structure. Significant characteristics of pAnca-UA*0101 include a specific flip of ∼88° and an upward shift adjacent to the C terminus of the α1- and α2-helical regions, respectively. Additionally, the lizard MHC-I molecule has an insertion of 2 aa (VE) at positions 55 and 56. The pushing force from 55-56VE triggers the flip of the α1 helix. Mutagenesis experiments confirmed that the 55-56VE insertion in the α1 helix enhances the stability of pAnca-UA*0101. The peptide presentation profile and motif of pAnca-UA*0101 were confirmed. Based on these results, the proteins of three reptile lizard viruses were used for the screening and confirmation of the candidate epitopes. These data enhance our understanding of the systematic differences between five classes of vertebrates at the gene and protein levels, the formation of the pMHC-I complex, and the evolution of the MHC-I system.

Background: We previously, reported that granulocyte-colony stimulating factor (G-CSF) reduces cardiomyocyte apoptosis in diabetic cardiomyopathy. However, the underlying mechanisms are not yet fully understood. Therefore, we investigated whether the mechanisms underlying of the anti-apoptotic effects of G-CSF were associated with autophagy using a rat model of diabetic cardiomyopathy.Methods: Diabetic cardiomyopathy was induced in rats through a high-fat diet combined with low-dose streptozotocin and the rats were then treated with G-CSF for 5 days. Rat H9c2 cardiac cells were cultured under high glucose conditions as an in vitro model of diabetic cardiomyopathy. The extent of apoptosis and protein levels related to autophagy (Beclin-1, microtubule-binding protein light chain 3 [LC3]-II/LC3-I ratio, and P62) were determined for both models. Autophagy determination was performed using an Autophagy Detection kit.Results: G-CSF significantly reduced cardiomyocyte apoptosis in the diabetic myocardium in vivo and led to an increase in Beclin-1 level and the LC3-II/LC3-I ratio, and decreased P62 level. Similarly, G-CSF suppressed apoptosis, increased Beclin-1 level and LC3-II/LC3-I ratio, and decreased P62 level in high glucose-induced H9c2 cardiac cells in vitro. These effects of G-CSF were abrogated by 3-methyladenine, an autophagy inhibitor. In addition, G-CSF significantly increased autophagic flux in vitro.Conclusion: Our results suggest that the anti-apoptotic effect of G-CSF might be significantly associated with the up-regulation of autophagy in diabetic cardiomyopathy.

Published: February 2021

Background:

Cervicogenic headache (CGH) is a secondary headache with a cervical source that radiates pain to the head or face. Accordingly, one reason of CGH is myofascial trigger points. The purpose of this study was to investigate the effect of one session dry needling (DN) of myofascial trigger points of the sternocleidomastoid (SCM) muscle in patients with CGH.

Materials and Methods:

In this before-and-after clinical trial, 16 females aged 18–60 years with a clinical diagnosis of CGH were enrolled. All of the patients received one session DN into the myofascial trigger points of the SCM muscle. Headache index (HI), headache duration, headache frequency, and headache disability index (HDI) were assessed at 2 weeks before and 2 weeks after the intervention. This study was registered in Clinical Trials as IRCT20181109041599N1.

Results:

One session DN into myofascial trigger points of the SCM muscle showed a significant improvement in HI (P < 0.001). Duration and frequency of headache as well as HDI significantly reduced after intervention (P < 0.001).

Conclusion:

One session DN into myofascial trigger points of the SCM muscle was effective on improvement of HI, headache duration, headache frequency, and HDI in patients with CGH.

Introduction:

Patients with sleep-related breathing disorders (SRBD) have various structural and functional abnormalities of the upper airway during sleep which may get reflected on their pulmonary function tests. The aim of the study was to find the correlation between the spirometric indices and snoring, grades of apnea–hypoapnea index (AHI), and STOPBANG. There is scarcity of literature showing correlation of STOP BANG with spirometric variables.

Material and Methods:

Patient with SRBD fulfilling the inclusion and exclusion criteria were enrolled. The pretest probability sleep score STOPBANG and polysomnography (PSG) were calculated for all the patients. Spirometric indices like forced expiratory volume in one sec (FEV1), forced vital capacity (FVC), postbronchodilator ratio FEVI/FVC (PBDR), and peak expiratory flow rate (PEFR) were studied. Their association with snoring, different grades of obstructive sleep apnea (OSA), and STOPBANG were evaluated using statistical analysis.

Results:

A total of 70 patients were enrolled. Abnormalities of spirometric indices were found to be common in patients with SRBD but their association with snoring, grades of OSA, and STOPBANG were not statistically significant. There is no statistically significant correlation between body mass index (BMI) and grades of AHI.

Conclusion:

This study found no statistically significant correlation between spirometric parameters and STOPBANG and degree of AHI. Primary care physicians should be aware that obstructive lung disease does coexist with the sleep disordered breathing but as per this study, their statistically significant association needs further validation.

Published: February 2021

Bupropion is taken as an antidepressant for treatment of major depressive disorders, treatment of sexual side effects of selective serotonin reuptake inhibitors, and as a smoking cessation aid, however, it may result in adverse effects such as nausea, dry mouth, headache, insomnia, dizziness, anxiety, tremor, and constipation. We investigate the case of a 34-year-old woman with bulimia nervosa where acute dystonia was induced by bupropion in 8 months. Following this diagnosis and after normal tests and MRI results, the patient was advised to discontinue bupropion intake. In the follow-up done 2 weeks later, 3 months later, and 6 months later, no signs of acute dystonia was observed. A physician who administers dopamine blocking agents must be aware of the prevalence of and the risk factors for acute dystonia and also the way of prevention and treatment.
