Authors: Chafik Mhamdia , Reda Belmamoun Ahmed , Afaf Baki 
Published: May 2022

The aim of our work is to evaluate the antioxidant activity of two parts (leaves and roots) of a methanolic extract of Urtica dioica L.
The study of the chemical composition revealed that the leaf extract is richer in polyphenols, flavonoids and tannins than the root extract.
The evaluation of the antioxidant effect showed that the inhibition reached its maximum at the highest concentration (initial DPPH concentration = 5000 μg/ml) equal to 89.25 ± 0.0022% for ascorbic acid against 67.17 ± 0.0013% (p<0.05) for the methanolic extracts of the leaves and 17.36 ± 0.0040% (p<0.001) of the roots.
The methanolic extract of the leaves has a strong scavenging power of the ABTS˙+ radical with an IC50 equal to 6.59 ± 0.0060 μg/ml, equal (p> 0, 05) to that of ascorbic acid (4.67± 0.0044 μg/ml) and pyrogallol (IC50= 548.7 ± 0.084 μg/ml), with an IC50 of 481.2 ± 0.34 μg/ml for roots, against the latter.

Published: May 2022

ABSTRACT

Objectives
To analyze the anatomical limitations and characteristics of maxillary and mandibular retromolar regions affecting molar distalization using cone-beam computed tomography (CBCT).

Materials and Methods
A total of 120 qualifying patients were classified into equal groups of skeletal Class II and Class III and stratified by vertical growth pattern, age, sex, and third molar presence. The available distance along the axis of distalization and cortical bone thickness (CBT) were measured in the maxillary and mandibular retromolar regions of Class II and Class III patients, respectively. One-way analysis of variance was used to examine the effects of the factors on the measured data.

Results
The minimum available distance of the Class II maxilla was observed at a level 3 mm from the cementoenamel junction (CEJ), while that of the Class III mandible was at a level 9 mm from the CEJ. The average available distance at the limit level was 4.06 ± 1.93 mm in the Class II maxilla, and the average corresponding CBT was 1.00 mm. The average available distance at the limit level in the Class III mandible was 2.80 ± 1.96 mm, and the corresponding CBT was 2.24 mm. In both skeletal Class II and Class III patients, hyperdivergent groups had the least available distance for molar distalization.

Conclusions
The limit for available distance in the Class II maxilla is closer to the coronal level, while that of the Class III mandible is closer to the apical level. A hyperdivergent growth pattern in a patient is indicative of less potential for molar distalization. Axial slices of CBCT images provide valuable evaluation for molar distalization regarding limit levels.

<p> </p>
<p>Prevention of immune rejection without immunosuppression is the ultimate goal of transplant immunobiology. One way to achieve this in cellular transplantation, such as with islet transplantation, is to create a favorable local environment at the transplant site. In the present study, we found that streptozotocin (STZ)-induced diabetic C57BL/6 mice remained normoglycemic for more than one year after transplantation of BALB/c islets without immunosuppression when the inguinal subcutaneous white adipose tissue (ISWAT) was the site of transplantation and when the site was pretreated with basic fibroblast growth factor. Mechanistically, mesenchymal stem cells (MSCs) expanded in the ISWAT after the treatment was found to produce TGFb and prevention of islet allograft rejection could be achieved by co-transplantation with syngeneic MSCs isolated from the ISWAT after the treatment, which was abolished by anti-TGFb antibody treatment. Importantly, TGFb-producing cells remained present at the site of co-transplantation for up to the end of observation period at 240 days after transplantation. </p>
<p>These findings indicate that prevention of islet allograft rejection without immunosuppression is feasible with the use of syngeneic TGFb-producing MSCs expanded in the ISWAT after the treatment with bFGF, providing a novel strategy for prevention of islet allograft rejection without immunosuppression. </p>

El presente artículo busca aportar una reflexión sobre dos recientes sentencias de la Corte Suprema de Justicia de la Nación en materia de relaciones colectivas de trabajo: “APSAI” y “Romero”. Analizaremos ambas sentencias, en sus diferentes instancias, hasta arribar a la decisión de la Corte Suprema. Estimamos que ambas sentencias, dentro de sus tendencias jurisprudenciales, vienen a complejizar aún más el panorama de tratamiento de diversas temáticas neurálgicas sobre las asociaciones sindicales de trabajadores/as y sus representantes.
En la primera sentencia, trataremos la retención de cuotas sindicales por parte de las asociaciones simplemente inscriptas y en la segunda, abordaremos la tutela sindical de los representantes gremiales. Como conclusión preliminar, podemos aseverar que la Corte mediante distintos tecnicismos y apreciaciones del caso en concreto, ha dado nuevos giros en materia de relaciones colectivas, mediante la negación de, a su vez, tendencias decisorias de otros años.
Si bien se trata de casos muy específicos, es sabido que los fallos del Máximo Tribunal son influyentes para otras instancias judiciales, a la vez que instalan estándares en la misma instancia extraordinaria, y de ahí la importancia en su análisis.

Abstract
The research on land-use transfer has always been a hot spot for domestic and foreign scholars, and it is also the focus of practical works. In China, the Beijing Municipal Government has put forward many forestry policies, emphasising the need to improve the collective forest land transfer system against the new background of the capital’s forestry development. This paper built a binary logistic regression model and structural equation modelling (SEM) based on the theory of planned behaviour (TPB), collected research data through questionnaires and explored the factors that affect the willingness of the transfer of forest land. The research showed that (1) farmers’ attitudes and behaviours had significant negative impacts on the willingness to transfer forest land. When farmers are assured that they know more about the forest land’s management rights transfer policy, and the forest land’s management rights transfer can bring more income to them, they will be satisfied with the existing forest land policy, which is more conducive to the forest land’s management rights transfer; (2) the perceived behaviour control of farmers had no significant impact on the willingness of forest land’s management rights transfer, that is, difficulties that farmers perceived in the implementation of forest land’s management rights transfer did not significantly affect their decision-making willingness and (3) the different results of the two models’ analysis on the impact of subjective norm on the willingness of forest land’s management rights transfer need further study and verification.

Abstract
This research examines the factors that affect Photo Voltaic (PV) solar technology’s usage intention in rural households in Bangladesh. The conceptual model for this research was developed according to past studies. There were five hypotheses developed and verified in this study. Cross sectional quantitative method was used in this research. The model was tested using empirical data collected from 209 households. This research mentions that PV solar technology usage intention was predicted by environmental concern, environmental knowledge, adoption cost, awareness, and government initiatives. The model shows a larger proposition (95 %) in the variance of PV solar technology usage in rural households in Bangladesh. According to the results of this study, we have accepted all hypotheses (H1–H5). From a practical perspective, this study’s results provide a guideline for investment decisions for the usage of PV solar technology in Bangladesh.

Objective:
This study aims to describe knowledge, attitudes, and practices about human immunodeficiency virus/ acquired immunodeficiency syndrome (HIV/AIDS) among a sample of 563 urban workers in Lubumbashi, in the Democratic Republic of the Congo.

Material and Methods:
This was a cross-sectional study where workers’ knowledge of HIV/AIDS was measured through a French adaptation of the Brief HIV Knowledge Questionnaire.

Results:
Overall, the level of knowledge of participating workers was poor (81.9%). Working in a private company (adjusted odds ratio [aOR] = 2.0 [1.2–3.3]) and having previously tested for HIV/AIDS (aOR = 2.5 [1.5–4.3]) were associated with good knowledge level about HIV/AIDS.

Conclusion:
Our results highlight the importance of implementing different awareness and education strategies for workers.
The Historical and Source-Based Aspects of Studying Early Russian Silent Film Posters of 1908—1919
Authors: Mikhalkina Ekaterina M. 
Published: May 2022

The Russian State Library holds one of the largest collections of Russian posters. Film posters from the time before the cinematography nationalization in 1919 are presented there in more than 250 sheets. Most of them advertise Russian films, more than a third — foreign ones, 25 sheets — documentary cinematography and newsreels of the Russian branch of the French firm “Pathé Brothers”.Recently, there has been a growing researchers’ interest in this period. Active popularization is being carried out by holding exhibitions and publishing catalogs of the largest collections, this phenomenon is discussed in detail at the beginning of the article.As well as cinematography, a film poster is a synthetic work. It represents a piece of graphic art, which is a commercial advertisement for another type of art. This research is aimed at studying film posters as a historical source that can tell us a lot: about characteristic social trends, about filmmaking as a process and about films themselves, about tendencies in the visual arts, about advertising of that period in general and about itself as a new type of advertising in particular.The article shows the history of the film poster formation as a product of commercial advertising and its subsequent development into a separate type of spectacular poster. There is analyzed its potential as a source on the history of cinema. In conclusion, the film posters are presented as a reflection of the era and society, which reacts to fundamental changes in the country.

Description du sujet. L’étude de la qualité physico-chimique de l’eau vise une connaissance des risques écologiques que l’activité d’extraction du sable peut engendrer sur l’environnement et ses ressources. Objectifs. Évaluer l’impact de l’extraction du sable fluvio-lagunaire sur la qualité physico-chimique de l’eau des écosystèmes aquatiques du sud-Bénin. Méthode. Les données ont été collectées mensuellement de décembre 2018 à novembre 2019 au niveau de 16 stations dont huit stations draguées et huit stations non draguées (stations de références). Treize paramètres physico-chimiques dont neuf paramètres (température, pH, transparence, profondeur, salinité, oxygène dissous, conductivité électrique, Solides Totaux Dissous, vitesse du courant) sont analysés in situ et quatre autres (NO2-, NO3-, NH4+, PO43-) au laboratoire. Le test de Kruskal-Wallis, la Matrice de Corrélation, la Classification Hiérarchique Ascendante et l’Analyse en Composantes Principales (ACP) ont été utilisés pour l’analyse des données collectées. Résultats. Les résultats ont permis d’identifier les effets de l’activité d’extraction du sable sur la physico-chimie de l’eau des écosystèmes aquatiques à travers l’analyse des stations draguées et des stations non draguées. Les stations non draguées présentent des eaux fortement minéralisées associées également à une pollution azotée et phosphorée, ce qui pourrait créer un déséquilibre au niveau de la faune aquatique. Par contre, les stations soumises à l’activité d’extraction du sable présentent les caractéristiques d’eaux bien oxygénées, des pH qui tendent vers la basicité, des eaux bien transparentes et profondes. Les résultats de cette étude montrent que les eaux des milieux dragués sont bien oxygénées et pourraient être bien favorables avec le temps au bon développement des espèces aquatiques, lorsque ceux-ci retrouveront peu à peu leur stabilité et redeviendront riches en matières minérales et nutritives. Conclusions. Cette étude permettra aux chercheurs et aux services techniques en charge de l'environnement de mieux appréhender les effets de l'activité d'extraction du sable sur la qualité physico-chimique des eaux des hydrosystèmes pour une meilleure gestion de ces milieux.

Tujuan pelaksanaan pelatihan flourishing untuk membantu anggota organisasi meningkatkan self compassion. Mahasiswa memiliki kesempatan mengembangkan diri secara akademis dan secara sosial selama belajar di perguruan tinggi. Usia mahasiswa saat belajar di perguruan tinggi biasanya berada pada masa emerging adulthood. Salah satu karakteristiknya ialah identity exploration yang terdiri dari eksplorasi relasi romantis, eksplorasi pekerjaan dan eksplorasi cara pandang akan dunia. Salah satu cara mahasiswa melakukan eksplorasi pekerjaan dengan mengikuti organisasi. Anggota Organisasi Mahasiswa Universitas X Surabaya juga mengalami hal serupa. Saat masa kepengurusan, sedang terjadi pandemi Covid-19 dan mengharuskan seluruh pelaksanaan kegiatan secara daring. Hal ini menyebabkan persoalan self compassion karena anggota organisasi memilih pasif, mengisolasi diri dan mengkritik diri berlebihan ketika mengalami kesulitan. Metode penelitian menggunakan teknik penelitian quasi experimental, yaitu teknik penelitian dengan menggunakan desain one group pretest posttest design. Pelaksanaan pelatihan selama 2 hari dan 6 sesi melalui aplikasi Zoom Meeting. Hasil analisis uji beda wilcoxon (0.289; p<0.05) menunjukkan adanya perbedaan self compassion antara sebelum dan setelah pemberian pelatihan flourishing, namun perbedaan yang terjadi tidak signifikan. Hal yang menyebabkan kondisi ini ialah interaksi sosial belum berfungsi secara utuh di dalam organisasi dan adanya faktor tahap perkembangan pada usia mahasiswa, sehingga pelatihan flourishing tidak dapat meningkatkan self compassion secara signifikan.

Published: May 2022

In the Baltic Sea, where osmotic stress limits the growth of marine organisms, mariculture is driven primarily by the need to improve the status of the environment. To this end, several mussel farms have been attempted in selected areas, except the southern Baltic. The pilot culture of Mytilus trossulus was carried out with the use of a modified long-line system in the Gulf of Gdańsk in 2009–2012, providing the first evaluation of the mussel farming potential in this area. The growth rate of mussels (3.0–6.7 mm year-1) in the gulf was in the low range, but the mean wet biomass gain (1.50 kg m-1 normalized culture rope) was among the highest in the Baltic. After a two-year growth period, one tonne of mussels fixed in their soft tissues from 93 to 98 kg N t-1 and 11 kg P t-1. The cost-benefit analysis revealed a negative budget balance of production for human consumption, with a total income covering only 12.0% of the cumulative costs. Mussel farming in the gulf can therefore only be justified to improve the environmental quality if additional funding mechanisms are put in place to support farming activity.
