La Mano: una lascivia di Michelangelo e i suoi effetti
Authors: Saracino Francesco
Published: June 2023

This essay presents the hitherto unknown copy of a drawing by Michelangelo representing a hand performing a lascivious act, and assesses the consequences of this invention in the artist's circle. It is an image that fits well into the burlesque tendencies of the Renaissance, and perhaps pertains to the ideology of the procreative artist; its scheme was even adapted to devotional and narrative contexts by some painters who observed the drawing among the papers of the “divine” – such as the Master of the Manchester Madonna, Battista Franco, and Girolamo Muziano. Michelangelo's Hand involved layered motivations and gives insight into some aspects of the master's imagination during his early maturity.
Cristofano Allori dans son dessin : le sujet dans le procédé d’étude
Authors: Pagliano Éric
Published: June 2023

In a book entitled The Subject in Painting, Daniel Arasse highlighted the anomalies and gaps likely to contain the “marks of the personality of their author” in works by Mantegna, Piero di Cosimo, Bellini, and Titian. He intended to show “how in the subject of a work the subject who painted it shines through.” This particular study is done in the footsteps of Arasse, but instead of starting from a completed work I will consider a preparatory drawing by the Florentine painter Cristofano Allori (1577–1621) as a point of departure. The challenge of this article is, thus, to show that the research methods specific to drawing employed to put in place a “subject-theme” can indeed refer to the “subject-artist” and even contain him or her: Allori studies his subject while “revealing himself” as a subject, and in this case his personal story is one of a tumultuous and passionate relationship with his mistress, La Mazzafirra.
Facile synthesis of a ZnO/Fe2O3 heterostructure and its graphene-reinforced composite for boosting the photo-mineralization of crystal violet and phenol
Authors: Shahid Muhammad
Published: June 2023

Herein, a nanostructured ZnO/Fe2O3 heterostructure and its graphene (Gr)-reinforced composite (ZnO/Fe2O3@Gr) have been synthesized via co-precipitation and post-ultrasonication approaches. The formation of heterojunction at the ZnO–Fe2O3 interface reduces the bandgap and keeps the electron-hole pairs apart. The graphene plays multiple roles to boost the dye removal effectively of the ZnO/Fe2O3@Gr composite. The charge transfer aptitude, isolation of charge carriers, and resistance at the ZnO/Fe2O3-Graphene interface were also examined by Mott–Schottky, chronoamperometric, and impedance experiments. The performance of an as-synthesized ZnO/Fe2O3@Gr catalyst was explored for the mineralization of a cationic dye (crystal violet, CV) and phenol in visible-light (λ above 400 nm) for 2 h. The ZnO/Fe2O3@Gr catalyst has mineralized 92.8 % CV dye and 50.86 % phenol after 2 h of visible-light irradiation. Moreover, the mineralization constant (k) comes to be 0.019 min−1, which is 4.2, 2.3, and 1.7 times higher than ZnO, Fe2O3, and ZnO/Fe2O3 catalysts, respectively. Increasing the dosage of the ZnO/Fe2O3@Gr catalyst from 10 mg to 30 mg increased the rate constant from 0.006 min−1 to 0.019 min−1, thereby increasing the efficiency of CV dye mineralization from 58.5 % to 92.8 %. The tuned photocatalytic activity of the ZnO/Fe2O3@Gr is due to the formation of the ZnO–Fe2O3 heterostructure and, preferentially, its conductive graphene. In fact, graphene serves the roles of an efficient electron collector, a transporter, and an effective UV/Vis light absorber, enabling the creation of active species that further boost the photocatalytic performance. According to the results of this study, the easiest and cheapest way to deal with toxic dyes in industrial waste is to make photocatalysts from semiconductive and carbonaceous materials that have integrated properties.

Published: June 2023

Industrial Revolution 4.0 requires individuals to have the ability in the field of technology and use it to solve existing problems. Computational Thinking (CT) is one of the skills needed in dealing with technological developments through a problem-solving process. Many research developments in the field of CT have been carried out, but the theoretical studies presented are still limited to the ability in solving problems using a computer. Whereas in its development, CT theory must be adapted to the scope and purpose of building it. Based on that, new research is needed which aims to test and analyze the truth of these findings and examine the stages of building appropriate CT for science students with state-of-the-art review method. By taking a specific scope that has not been studied by many researchers, namely science education, it is found that CT is the ability in dividing a problem into sub-steps, carry out deeper investigations, analyze and criticize and test the truth of something so that the right solution is obtained. This definition is more specific than the definition of CT in theory because it is adapted to the characteristics of science. Whereas from a state-of-the-art review of the stages of building CT, it was found that the stages of task decomposition, abstraction, generalization, data structures and algorithms were considered to optimalize the CT construction for science students. It is because students could identify tasks or problems and divide the problem into small parts at the task decomposition stage. Therefore, they can be completed one by one.

Learner support for reading problems in Grade 3 in full-service schools in the Gauteng province
Authors: Phala Thembi
Published: June 2023

In South Africa, the issue of learning to read is an area of concern. While studies have focused on reading problems in the Foundation Phase, little is known about this issue in full-service schools. In light of this, the aim of this study was to explore how Grade 3 teachers supported learners who experienced reading problems in full-service schools. Vygotsky’s sociocultural theory was used to understand the meaning-making of Grade 3 teachers in the context of reading. This qualitative study with a case study design was conducted in 3 full-service schools in the Tshwane North district in the Gauteng province. Participants included 6 learner-support teachers and 11 Grade 3 class teachers. Data were produced using semi-structured interviews. The findings show that the methods of reading and modes of working to support learners are complex, varied, and largely teacher-driven. This set of circumstances highlight the need for co-construction of reading with learners and the addressing of specific barriers to learning to read. This was somewhat evident among the specialist teachers but not sufficiently robust. This study raises questions for professional development for reading problems in the Foundation Phase.
Yabancı Uyruklu Üniversite Öğrencilerinde Yalnızlık ve Dini Başa Çıkma İlişkisinin İncelenmesi (Kilis Örneği)”.

Published: June 2023

Son yıllarda Türkiye’deki üniversitelerde öğrenim görmekte olan yabancı uyruklu öğrencilerin sayısı artmaktadır. Yapılan son araştırmalar, yabancı uyruklu öğrencilerin şehir ve üniversite yaşamında sosyal dışlanma ve yalnızlık gibi sosyal sorunlar yaşadıklarını göstermektedir. Yalnızlık, psikososyal iyilik hâli üzerinde doğrudan etkili bir kavramdır. Bu nedenle yabancı uyruklu öğrencilerde yalnızlık ve dinî başa çıkma becerilerinin incelenmesinin önemli olduğu görülmektedir. Çalışmanın amacı, yabancı uyruklu üniversite öğrencilerinin yalnızlık ve dinî başa çıkma düzeylerinin sosyo-demografik değişkenler bakımından ortaya konulmasıdır. Araştırmada, nicel araştırma desenlerinden korelasyonel araştırma yöntemi kullanılmıştır. Araştırmanın örneklemi ise 121 Suriye uyruklu 18 Afrika kökenli toplam 139 öğrenciden oluşmaktadır. Araştırma sonucunda, 20 yaş altı üniversite öğrencilerinin pozitif dinî başa çıkma düzeylerinin 20 yaş üzerindeki öğrencilerden yüksek düzeyde olduğu tespit edilmiştir. Türkiye’de ikamet süresinin uzamasının öğrencilerin pozitif yönde dinî başa çıkma düzeylerini artırdığı ayrıca öğrencilerin aile tiplerinin (anne-baba birlikte, parçalanmış, ebeveyn kaybı vb.) dinî başa çıkma ve yalnızlık düzeyleri üzerinde etkisinin olmadığı tespit edilmiştir. Öte yandan yabancı uyruklu öğrencilerde kardeş sayısı ile dinî başa çıkma ve yalnızlık arasında, gelir durumları ile dinî başa çıkma ve yalnızlık arasında anlamlı ilişki olmadığı, Suriye kökenli üniversite öğrencilerinin pozitif başa çıkma düzeylerinin, diğer uyruktan gelen öğrencilere göre daha düşük olduğu son olarak mühendislik fakültesi öğrencilerinin dinî başa çıkma düzeylerinin, diğer birimlerde öğrenim gören öğrencilerden yüksek düzeyde olduğu saptanmıştır.

Background: Badminton being one of the most popular and fastest racket sport, demands the players to have different skills and fitness level in-order to excel. Skills like power, agility, speed, dynamic balance and reaction time are few of them. Aim: This study aims to compare the effect of plyometric exercises versus speed agility quickness (SAQ) training on agility, speed, power, dynamic balance and reaction time in badminton players. Methods: An experimental study was conducted in 36 amateur badminton player who were divided in 3 groups with 12 participants in each - Plyometric training group, SAQ training group and control group. All received intervention for 6 weeks. The outcome measures used were a) agility- Illinois agility test, b) speed- 30 meters’ sprint test, c) power- vertical jump test, d) dynamic balance- modified star excursion balance test and e) Reaction time- simple visual reaction time task. Statistical analysis: Statistical analysis was performed using SPSS software, version 24. Paired t test was used to compare pre-post differences in each group. Intergroup comparison was evaluated using ANOVA test. Results: Plyometric group showed a significant improvement in the agility, speed, power, posterolateral and posteromedial directions in modified star excursion balance test and reaction time using paired t test. Speed Agility Quickness group revealed significant difference in speed, agility, all three directions in modified star excursion balance test. In control group, significant improvement was seen only in anterior and posteromedial directions in modified star excursion balance test. There was significant difference between the groups in agility, power and speed using ANOVA test. Further post hoc analysis revealed that plyometric and SAQ group showed no statistically significant difference when compared with each other except for power which showed more improvement in the plyometric group. Conclusion: Both plyometric and SAQ training were equally effective in improving speed and agility in badminton players. Power was seen to be improved more in plyometric group. Hence, these training protocols can be used as evidence-based approach to improve skills in badminton players for optimal performance.

Published: June 2023

A ocupação desordenada é um problema que atinge cada vez mais os grandes centros urbanos. Desta maneira, o objetivo deste estudo é realizar uma avaliação acerca das vulnerabilidades ambientais, sociais e econômicas decorrentes da ocupação irregular em Áreas de Proteção Permanente (APPs), através de um estudo de caso elaborado em áreas lindeiras a um trecho do Rio Beberibe, localizado na Região Metropolitana do Recife (RMR), com o intuito de identificar os impactos ambientais urbanos encontrados na área, para enfatizar a crescente necessidade de reestruturação e renaturalização destas. Para isto, foi realizada uma análise comparativa do uso e ocupação do solo através de ortofotocartas georreferenciadas da década de 1970, de 2013 e 2021. Ademais, foram realizadas visitas in loco para análise e coleta de dados. Os resultados identificaram que a ocupação da APP, em 2021, é de 35,91% para vegetação e 64,09% para área que sofreu intervenções antrópicas, sejam elas edificadas, impermeáveis ou solo exposto. Assim como, foram evidenciadas diversas inconformidades com a legislação ambiental. Desta maneira, observa-se a necessidade de programas de reestruturação destas margens e adoção de técnicas compensatórias de drenagem, sejam elas, estruturais ou não estruturais.

Este estudo, teve como objetivo principal a análise da formação sócio-histórica do bairro negro Niterói da cidade de Itaperuna-RJ, localizada no interior do Estado do Rio de Janeiro. Para tanto, precisamos compreender o que são os bairros negros, considerando o período afrodiásporico brasileiro, bem como refletir sobre a constituição do núcleo urbano de Itaperuna. Para a execução desse trabalho, nos fundamentamos no método da afrodescendência e no referencial teórico-metodológico dos percursos urbanos, tendo como coleta de dados, o levantamento iconográfico. Exploramos o conceito de bairros negros como uma proposição de entendimento das especificidades que caracterizam as populações negras nos espaços urbanos, visto que pouco se discute sobre as condições dos ex-escravizados após a abolição, sobre as atividades que desempenhavam e como se deu sua inserção no espaço urbano. Em nossas análises percebemos o rio Muriaé, inserido na paisagem urbana, como demarcador de segregação socioespacial pensada pela elite brancocêntrica, no intuito de manutenção das hierarquias sociais.

Study of Mobility Patterns in Metropolitan Region of Campinas, São Paulo, Brazil
Authors: Silva Janini de Oliveira Dias da , Martinez Pedro José Perez
Published: June 2023

The current model of Brazilian cities dependent on individual transport and the low coverage of collective systems in metropolitan regions has generated problems that make it difficult for the population to move and increase pollutant emissions into the atmosphere. This article aims to analyze mobility patterns and relate them to infrastructures and the urbanization process of the Metropolitan Region of Campinas (RMC). For methodological purposes, consultations were carried out on legislation, integrated urban development plans, master plans, metropolis statute and bibliographic review of scientific works on the themes, as well as a survey of the results of the Origin Destination Research, carried out in the region in 2011 and the use of geotechnologies (GIS). After document analysis and the calculation of indicators, it was identified that the pattern of urban-spatial organization in the region presents a strong socioeconomic polarization that directly affects mobility patterns and the absence of integration of public transport systems.

Adler’e göre insan davranışının oluşumunda kalıtımsal faktörler kadar sosyal çevre, bireyin çevresiyle yaptığı etkileşimler ve etkileşim süreci içinde fenomonolojik anlamlandırmaların da önemi vardır. Adler Kuramı’na göre birey seçicidir, tektir, karar alabilen ve hayatını şekillendirebilen bir varlıktır. İnsanın temel amaçları ve yaşamsal görevlerine değinilen kuramda; bireylerdeki organ eksikliği, aşağılık duygusu, sosyal ilgi ve doğum sırası gibi kavramların yaşam tarzını etkilediği; düşünce, duygu ve davranışların oluşumunda etkili olduğu vurgulanır. Kuramın temel kavramlarının birey, aile, grup ve toplumla çalışan Sosyal Hizmet disiplini için katkı sağlayıcı olduğu; terapötik ilişki kurulurken kuramdan faydalanıldığı ve insan davranışını anlamada geniş perspektif sunduğu bilinir. Teorinin daha iyi anlaşılması ve yaşamsal olaylar içinde değerlendirilebilmesi için vaka örneği üzerinde çalışmanın faydası yadsınamaz. Vaka örneği olarak, yazınsal kaynaklar kadar özellikle gerçek yaşam öykülerinden uyarlanan filmlerin analizinden de yararlanılmaktadır. Multidisipliner bir bilim olarak Sosyal Hizmet‘in sanatla da iç içe olması nedeniyle, sinemada yayınlanmış bir film üzerinden kuramı derinlemesine gözlemlenmek ve yorumlamak mümkündür. Bu nedenle, bu çalışmada sinema filminin analizi Adler Kuramı perspektifinden yorumlama yöntemiyle gerçekleştirilmiştir. Kuramın temel ilkeleri ve insana bakış açısı filmdeki somut olaylar üzerinden aktarılmıştır. Bu bağlamda Adler Kuramı ile birçok açıdan bağlantılı olduğu düşünülen, gerçek bir yaşam hikâyesinden uyarlanan ‘Yetenekli Eller: Ben Carson Hikâyesi’ filminin analizi yapılarak Adleryen bakış açısıyla film yorumlanmıştır. Çalışmanın amacı, sanat ve sosyal hizmet alanlarının kesişiminde insan psikolojisini anlamaya yönelik farklı bir bakış açısı sunmaktır.
FOR THE HISTORY OF THE OF THE OCCUPIED GEORGIAN TSKHINVALI’S LITERARY AND CULTURAL LIFE (The end of the XIX century and the beginning of the XX century)
Authors: MGHEBRİSHVİLİ Aleksandre
Published: June 2023

Basishvili, son of Samson Antoni, was one of the interesting figures in the literary and literary arena of the 19th-20th centuries of the Tskhinvali region. He was born next to Tskhinvali, village in kurta. In the population census of 1860 village Eight Basishvili households are mentioned in Kurta (naturally, the records indicate that they are ethnic Georgians). The surname of Basishvili is mentioned in many historical documents of previous centuries. In particular, the book of “sitarkhani” issued by Levan Machabeli to Meladze is dated to the first half of the 18th century, in the list of witnesses of which Katsia Basishvili is mentioned, as well as from Parsa of 1714 and Levan Machabli is the witness of the purchase book of Alkhaz Machabeli and Beri Akhalkatsisshvili. Sekhnia Basishvili is mentioned next to Ivane Maisuradze, Giorgi Goginashvili, Beri Mamukashvili and others, in the same document, "Sulkheli, Erpir Bassishvili" and others are generally mentioned as witnesses. (see tabuashvili, 2013) In Kurta, the representatives of this family were referred to as "Priests". Anton Basishvili (priest), Manase Basishvili (priest) and Samson Basishvili (priest) were buried in the yard of the Church of the Mother of God of Kurta. This last one was the person to whom we would like to draw the reader's attention today.
S. Basishvili had close, friendly relations with his contemporary writers and public figures. He was engaged in active creative and journalistic activities. In his own publications, he often wrote about the ongoing processes in his native village, agricultural works, lack of educational institutions, etc.
In addition to his clerical and publicist work, Samson Basishvili was actively involved in the cultural life of the region. His name is repeatedly found in the archive materials of the Tskhinvali branch of the Society for Spreading Literacy among Georgians.

Data klimatologi aktual diperoleh dari stasiun klimatologi terdekat sedangkan data prediksi merupakan data hasil perkiraan dari Climate Forecast System Reanalysis (CFSR) yang dilaksanakan oleh National Centers for Environmental Prediction/Environmental Modeling Center (NCEP/EMC) yang tersedia di 4 stasiun di sekitar Sub DAS. Pada awalnya model mensimulasikan debit dari Sub DAS menggunakan input data klimatologi aktual yang hasilnya dikalibrasikan dengan data debit tercatat pada pos duga air. Model dengan parameter terbaik kemudian digunakan untuk mensimulasikan tiga skenario simulasi menggunakan data input klimatologi hasil prediksi, adapun skenarioskenario tersebut adalah (1) data dari satu stasiun terdekat, (2) data dari dua stasiun terdekat dan (3) data dari empat stasiun terdekat. Hasil kalibrasi model menunjukkan bahwa model memiliki kinerja cukup baik dengan nilai koefisien determinasi 0.67 dan koefisien Nash-Sutcliffe 0.37. Aplikasi data klimatologi hasil prediksi menunjukkan bahwa, data prediksi dari satu stasiun terdekat menghasilkan kinerja model yang lebih baik. Sementara itu semakin banyak stasiun yang digunakan sebagai input data akan menghasilkan hasil simulasi yang semakin mendekati hasil simulasi dengan menggunakan data aktual.SWAT Model Application To Simulate Discharge From Krueng Meulesong Sub Watershed Using The Actual And Predicted Climatological DataABSTRACT. The Soil and Water Assessment Tool (SWAT) hydrological model was used to simulate discharge from Krueng Meulesong subwatershed located in Aceh Besar District using actual and predicted climatological data. The actual data were collected from the nearest local meteorological station while the predicted data was the results of Climate Forecast System Reanalysis (CFSR) completed by National Centers for Environmental Prediction/Environmental Modeling Center (NCEP/EMC) through four stations located around the subwatershed. The model was initially developed using actual data and then calibrated with observed streamflow data. The best model then was rerun using 3 scenarios of predicted data i.e. (1) data from the nearest station, (2) data from average of the two nearest stations and (3) data from average of four nearest stations. The model performance was categorized into satisfactory with determination and Nash-Sutcliffe coefficients were 0.67 and 0.37, respectively. Comparing the model performance resulted from predicted data suggested that using the nearest station data would produce a better model performance. Meanwhile, incorporating more predicted data stations around subwatershed would cause the model to produce simulated streamflow similar to the streamflow using the actual data.

Authors: Yanda Rian Juli , Syah Hendri , Agustina Raida
Published: June 2023

Abstrak. Ubi kayu merupakan salah satu tanaman yang mengandung karbohidrat. Ubi kayu dapat dikeringkan untuk mendapatkan produk olahan contohnya pembuatan tepung dan gaplek. Pada penelitian ini dilakukan modifikasi pengering surya dengan menambahkan kincir angin savonius sebagai penggerak kipas pada pengering tersebut yang bertujuan untuk memaksimalkan sirkulasi udara didalam ruang pengering. Parameter yang dilakukan diantaranya pengukuran kecepatan udara, distribusi temperatur, kelembaban relatif, iradiasi surya dan pengukuran kadar air. Dengan penambahan kincir angin savonius, kecepatan udara di dalam pengering surya lebih stabil bila dibandingkan dengan kecepatan udara di lingkungan. Temperatur di dalam ruang pengering lebih tinggi dari pada temperatur lingkungan, sedangkan kelembaban relatif di dalam pengering lebih rendah dibandingkan dengan di lingkungan. Hal ini menyebabkan proses pengeringan berlangsung cepat. Nilai iradiasi surya yang didapat berfluktuasi. Iradiasi tertinggi diperoleh pada hari kedua penelitian yaitu 595 W/m2. Kadar air awal ubi kayu yaitu 61,7 %. Kadar air akhir yang diperoleh rak A5 yaitu sebesar 11,7% dan rak B1 yaitu sebesar 12,9% sudah mendekati kadar air yang diharapkan untuk  pembuatan tepung yaitu 12%. Performance of Solar Dryer by Using Savonius Windmill for Cassava (Manihot esculenta) DryingAbstract. Cassava is one of the plants that contain carbohydrates. Cassava can be dried to produce processed products such as cassava flour and “gaplek”. In this research, the solar dryer was modified by adding a savonius windmill as fan drive which aims to maximize the air circulation inside the drying chamber. The observed parameters include air velocity, the distribution of temperature, relative humidity, solar irradiation and the water content. The addition of savonius windmill caused the air velocity in the solar dryer was more stable when compared to the speed of the air in the environment. Moreover, the temperature in the drying chamber was higher than the ambient temperature, while the relative humidity in the dryer was lower than in the environment. As a result, it caused rapid drying process. Solar irradiation values obtained fluctuate. The highest irradiation was obtained on the second day of the study (595 W / m2). The moisture content of the cassava decreased from  61.7% to 11.7% (at A5 rack) and 12.9% (at B1 rack). Those values was approaching the expected flour water content (12% ).

Adicionalmente, se propone la implementación de la geoética en las carreras de ingeniería geológica y geociencias para promover la responsabilidad social y ambiental entre las y los jóvenes graduados y científicos que inician su carrera, a fin de prevenir prácticas profesionales negativas y mejorar la visibilidad de las geociencias y sus beneficios para la sociedad. El artículo concluye llamando al involucramiento de los geocientíficos en las políticas públicas para la protección del patrimonio geológico y la promoción de los valores geoéticos, así como la creación de un grupo profesional para desarrollar y promover la didáctica de las geociencias para mejorar la calidad educativa en el campo.
Fossil relatives of extant parasitic crustaceans from the Mesozoic of Europe
Authors: Schädel Mario , Nagler Christina , Hyžný Matúš
Published: June 2023

The fossil record of Isopoda includes remains of presumed parasites. Among the fossils which have been discussed as potential parasites are those termed as Urda Münster, 1840. Some of these fossils have been discussed as possibly related to an extant group of parasites, Gnathiidae Leach, 1814. The type species of Urda – Urda rostrata Münster, 1840 – is herein interpreted as a close relative of the group Gnathiidae, based on the shared occurrence of a number of apomorphic features. This is with Urda punctata (Münster, 1842) herein being interpreted as a junior subjective synonym of U. rostrata. However, not all of the fossils associated with the name Urda can safely be identified as close relatives of Gnathiidae. Moreover, it is unclear whether the extinct species, which can be identified as close relatives of U. rostrata and Gnathiidae form a monophyletic group, as we could not identify an autapomorphy for a natural group Urda. A new species of close relatives of Urda rostrata and Gnathiidae – Urda buechneri n. sp. – is formally described based on µCT image data. Palaega suevica Reiff, 1936 and Palaega kessleri Reiff, 1936 are found to be subjective synonyms and are re-interpreted as Urda suevica n. comb. – a species closely related to U. rostrata. Due to the documented destruction of the holotype, a herein figured fossil specimen is designated as the neotype of Urda suevica. Palaega? stemmerbergensis Malzahn, 1968 is also interpreted as a close representative of U. rostrata and herein treated as Urda stemmerbergensis n. comb. Another already formally described species – Eobooralana rhodanica gen. et comb. nov. – is interpreted as a more distant relative, which is likely to be closer related to other extant species of Isopoda than those within Gnathiidae. For three species there are not enough characters preserved to interpret them as closely related to U. rostrata and Gnathiidae: Urda? liasica Frentzen, 1937 nom. dub. (type material destroyed, description insufficient for proper diagnosis), Urda? moravica Remeš, 1912 and Urda? zelandica Buckeridge and Johns, 1996.

New Dermaptera taxa (one new genus and four new species) are reported from amber pieces proceeding from Mina Los Pocitos near Simojovel de Allende, Chiapas. The amber pieces were collected in the lower Miocene Mazantic Shale, including well-preserved earwigs, with only one antecedent for this insect group in the Mexican amber. The presence of this kind of insects supports the paleoenvironmental interpretation for the Mazantic Shale amber as of a humid forest.

Authors: Behnam Shayesteh , Zavareh Saeed , Salehnia Mojdeh
Published: June 2023

Objective: Oxidative stress affects the development of ovarian follicles during in vitro culture thus applying an antioxidant is necessary. The aim of this study was to investigate the effect of coenzyme Q10 (CoQ10) on the expression of apoptosis-related genes of mouse ovaries during in vitro culture.
Materials and methods: The immature mouse ovaries were cultured in the presence of 50 μM CoQ10 for 7 days. Histological examinations were performed and the 17 beta-estradiol concentration was measured on the seventh day of culture. The relative expression of Caspase 3, Bax, Bad, and Bcl 2 genes were investigated by real-time RT-PCR.
Results: The rates of normal follicles in the presence of CoQ10 was significantly increased compared to the control group. Also, in CoQ10-trated group a significant increase in the level of 17 beta-estradiol was seen compared to the control group. The mRNA expression of anti-apoptotic gene Bcl2 was significantly increased while the expression of pro-apoptotic genes (Caspase3, Bax and Bad) significantly declined in CoQ10 treated group compared to those of control group.
Conclusion: The supplementation of the ovarian culture media with CoQ10 improved the follicular development through alteration in expression of apoptosis-related genes and stimulated the production of estradiol.

Authors: Quental Carolina , Brito Daniel Bertoluci , Sobral João , Macedo Ana Mafalda
Published: June 2023

Objective: In Raynaud's phenomenon of the nipple there is a change in color, accompanied by pain or discomfort during breastfeeding.
Case report: A 29-years old female patient, breastfeeding, develops a severe bilateral nipple pain during and after breastfeeding and biphasic change in nipple color, with difficulties in the breastfeeding technique. She was medicated with nifedipine and recommended application of warm compresses to the nipples and use of electric breast pump, showing complete resolution after four weeks of treatment.
Conclusion: Raynaud's phenomenon of the nipple should be considered in breastfeeding women who report nipple pain or discomfort. In clinical practice, nipple pain is a very frequent complaint, and responsible for many cases of early abandonment of breastfeeding. It is therefore essential to make an early diagnosis and implement a correct and immediate treatment.

Background: Allergic rhinitis is a very common disease which its clinical symptoms can reduce the patient’s quality of life. This study aimed to compare the effects and side effects of desloratadine with fexofenadine on allergic rhinitis.
Methods: The present study is a clinical trial on 68 patients with allergic rhinitis who were randomly divided into two groups named A and B. In the A group, patients used 120 mg of fexofenadine for 4 weeks and in the B group, patients received 5 mg of desloratadine for 4 weeks. After two weeks of rest, patients in the A group received desloratadine, and patients in the B group received fexofenadine for 4 weeks. Then, the clinical conditions and efficiency of the drugs in both groups were compared.
Results: The severity of symptoms significantly decreased in the A and B groups before and after the treatment (p<0.001 and p=0.007, respectively). The severity of symptoms after taking the first and second drugs in the A group was lower than in the B group. In the A group, the changes in symptom severity after taking the first and second drugs were significantly greater than in the B group. Other symptoms were not significantly different between the two treatment groups (p>0.05 in all cases).
Conclusion: In patients with allergic rhinitis, the use of fexofenadine compared to desloratadine can more effectively reduce the severity of the symptoms of the disease and can be prescribed as a suitable treatment option for these patients.

Published: June 2023

Background: This study aimed to determine the distance between the hard palate and the tongue and its relationship with Nasal Septal Deviation (NSD).
Methods: This descriptive-analytical study was conducted on patients aged 18 to 60 years referred to the ENT clinic of Milad and Masih Daneshvari Hospitals. Patients were also divided into two groups (patients with and without NSD). Coronal CT scan was taken in all patients in the same position. In this regard, these pictures were taken vertically from the highest point of the hard palate to the tongue, the transverse distance between the two upper third molars of the upper jaw, and the ratio of these two distances.
Results: The mean age of patients with and without NSD was 35.8212.49±, and 33.9912.78± years old (p=0.66). The distance of hard palate to tongue in patients with and without NSD was 13.05±4.52, and 12.26±4.68 mm, respectively (p=0.32). The intermolar distance in these patients was 34.2±3.50, and 34.40±3.31 mm (p=0.78), respectively. This ratio in the two groups was 0.380.13±, and 0.340.11±, respectively (p=0.16).
Conclusion: According to these findings, no significant difference was observed between the patients with and without NSD regarding the distance between the hard palate and tongue, intermolar distance, and its ratio, but the distance of hard palate to tongue, and the ratio in the patients with NSD was slightly higher than patients without NSD. Further studies using coronal CT scan in larger samples are needed to clarify the role of the distance of hard palate and the tongue in NSD.

Background: We conducted this study to determine the safety and evidence of effectiveness of SeptimebTM among patients with COVID-19.
Methods: An uncontrolled phase II clinical trial with SeptimebTM was implemented in Imam Khomeini Hospital as a before-and-after trial during May to October 2020. Considering the inclusion and exclusion criteria, 33 patients with COVID-19 were treated using SeptimebTM. The patients received the anti-inflammatory drug 150 mg /10 ml /IV infusion SeptimebTM on the first day and then 300 mg /20 ml / IV infusion from the second day onwards for at least 2 days and up to 13 days based on the improvement of clinical symptoms and laboratory findings in addition to treatment which were selected according to the national protocol. The patients were then evaluated for the treatment efficacy and side effects. Adherence to treatment, clinical observations, and side effects were recorded before and after the treatment.
Results: The herbal drug SeptimebTM was injected in phase two of an uncontrolled clinical trial on 33 patients with COVID-19 in Imam Khomeini Hospital in Tehran as a before-and-after trial. The number of new cases admitted to the Intensive Care Unit (ICU) and the new need to Non-Invasive Ventilation (NIV) ecreased compared to before the treatment. Also, blood oxygen saturation and platelet count increased. Conversely, CRP, ESR, and ferritin levels decreased (p<0.05). Besides, SeptimebTM did not show any serious side effects except recurrent thrombophlebitis during the treatment.
Conclusion: We found some evidence regarding the efficacy of this drug and its low amount of short term side effects. The investigators recommend conducting the third phase of the clinical trial.

Published: June 2023

Background: The current study decided to assess CT scan findings in patients with any kind of pleural effusion to obtain any diagnostic value of this modality of imaging to discriminate malignant conditions from benign ones, especially pleural or pulmonary tuberculosis.
Methods: Through a cross-sectional design, patients with pleural effusion enrolled in this study when their diagnosis was known as malignancy or tuberculosis. The findings of chest CT-scan were compared between the two conditions and the frequency and statistically different variables were reported as discriminating factors between malignancy and tuberculosis.
Results: Among our findings, male sex was prone to tuberculosis, but pleural thickening >10 mm, lung collapse and lung mass in CT-scan, were the most prevalent findings in malignancy and absent in tuberculosis cases. No significant differences were observed in the free or loculated effusion, air-fluid level and gas, Hounsfield score and loculation involvement between groups.
Conclusion: CT scan, despite its unconfirmed diagnostic values, could be considered as a very useful part of diagnosing malignancies against benign or infective causes of pleural effusion, especially in terms of pleural thickening more than 10 mm, lung collapse and lung mass disregarding transudative or exudative as well as uni- or bilateral, free or loculated, mild or severe, or other kinds. CT scan scoring system may be the next topic to work on by authors.
