Objective: to identify the presence of chronic endometritis in patients with adenomyosis and its cumulative role in the formation of reproductive losses. Materials and methods: 101 women of reproductive age with grade II adenomyosis and habitual miscarriage were examined. The comparison group (group 2) consisted of 49 patients with grade II adenomyosis without a history of early reproductive losses. The control group (group 3) consisted of 50 healthy patients. In order to diagnose chronic endometritis, a comprehensive immunohistochemical study of the expression of specific immunological markers of chronic endometritis (natural killer CD56, B cells (CD20), plasma cells (CD138) and activated lymphocytes (HLA-DR) with antibodies and the determination of CD68 macrophages was carried out. Polymerase chain reaction in the “real-time” mode (PCR) was used to determine the types and amount of endometrial microbiota. Statistical data processing was carried out in the environment of the STATISTICA package. Results: despite the absence of pathogenic and conditionally pathogenic microflora, according to the results of microbiological examination from the vagina and cervical canal of all examined patients, statistically significant differences in the detection frequencies of various microbiota taxa of crops from the uterine cavity were obtained. Patients with reproductive losses on the background of adenomyosis had microbiological and immunohistochemical signs of chronic endometritis of moderate and mild severity. The presence of chronic endometritis combined with adenomyosis contributes to the occurrence of pronounced endothelial dysfunctions, eventually leading to a violation of reproductive function in patients with a combination of HE and adenomyosis. Conclusion: The similar symptoms of adenomyosis and CE, a reliable association of adenomyosis with CE in patients with habitual miscarriage requires the inclusion of immunohistochemical and microbiological examination of the endometrium in the volume of pre-gravidar examination, even if there are negative results of microbiological examination of the environment of the cervical canal.

Authors: Radojičić Jelena , Radović Ognjen 
Published: July 2023

This paper examines the market efficiency of the most significant cryptocurrencies, Bitcoin and Ethereum. In the paper, we use several different tests to check the normality of return distribution, long-run correlation and heteroscedasticity of return volatility.We compare the characteristics of cryptocurrency returns with the returns on stocks of the most important companies producing hardware components for cryptocurrency mining. The correlation of returns, trading volume and volatility between cryptocurrencies and selected stocks is tested using a Granger causality test. The research results reject the efficient market hypothesis and show that the cryptocurrency market is a completely new speculative market that is weakly correlated with the stock market.

Published: July 2023

This research aims to assess and analyze the financial performance of public companies operating under the Sharia category during the Covid-19 pandemic. The Altman Z-Score method, which utilizes four parameters and secondary data, was employed to investigate the 2020 financial statements of 30 companies listed in the Sharia category in JII. The study findings indicate that three companies exhibited potential bankruptcy as their Z-Score value was less than 1.1, while three other companies were susceptible to bankruptcy with a Z-Score value between 1.1 and 2.6. In contrast, 24 companies were classified as financially healthy since their Z-Score value was greater than 2.6. To mitigate the risk of bankruptcy, management is advised to implement effective debt restructuring and management strategies while examining best practices from companies that thrived during the pandemic. This research underscores the effectiveness of the Altman Z-Score method in assessing financial performance, identifying financial issues, predicting bankruptcy, and evaluating a company's financial health level.======================================================================================================== ABSTRAK – Kinerja Perusahaan Publik Syariah Pada Masa Pandemi Covid-19: Analisis Altman Z-Score.

Published: July 2023

Historical studies are a vital discussion in various social sciences and humanities, including Islamic studies. Islam and Muslims are not static entities, but a continuous fact. In Islamic studies, a historical approach has actually been carried out, not only in relation to the chronology of Islamic development. This research uses descriptive qualitative research methods. The data were taken from historical science literature, then analyzed by theoretical hermeneutics which were then analyzed using the triangulation method, namely by conducting a cross check between theories in the historical method. The results of this research show that there are aspects of Islamic history that must be understood objectively so as not to lose the orientation of space and time, so that all doctrines, schools of thought and civilization in Islam can be presented objectively.Keywords:Â History;Â Methodology; Islamic Studies.

Published: July 2023

ABSTRACT

Objective
To assess soft tissue differences between monozygotic twins (MZ) for the total face and between facial regions using three-dimensional (3D) stereophotogrammetry and quantitative surface-based 3D deviation analyses.

Materials and Methods
The study sample consisted of 14 untreated MZ twins (6 males, 8 females, mean age: 14.75 years) from the archive of Marmara University, Department of Orthodontics. The images were taken by the 3dMDface system, and 3dMDvultus software was used for removal of undesired areas and approximation of the images. Then, stereolithography (.stl) format images were superimposed using the best-fit algorithm using 3-matic software. The face was divided into facial thirds, and upper lip and lower lip + chin regions were created. For the comparison, 3D deviation analyses were performed, and a color map and histogram were created. The data were presented as mean deviation, root mean square (RMS), median, and interquartile range.

Results
Between the facial thirds, there was no significant difference in soft tissue differences for mean deviation. A statistically significant difference was found between the upper and lower face for the RMS value. For the comparison of upper lip and lower lip + chin region, the only significant difference was for the RMS. When the data were presented as median and interquartile range, there were no statistically significant differences between any facial regions.

Conclusions
Lower facial third and lower lip + chin regions had the greatest differences within MZ twin pairs. The genetic and environmental influences might not be the same for different parts of the face.
Condições do Ensino Médio para a oferta de itinerários formativos no Brasil
Authors: Fernandes Edison Flávio 
Published: July 2023

O estudo objetiva trazer uma base diagnóstica sobre as condições atuais das escolas de ensino médio no País, bem como de seu professorado, tendo em vista a corrente reforma dessa etapa de ensino, especificamente a oferta de itinerários formativos, de modo a contribuir com os debates no âmbito do novo Plano Nacional de Educação (PNE).
Metodologicamente, são investigados a quantidade e a infraestrutura das escolas que ofertam o ensino médio no Brasil, os níveis de adequação da formação e de esforço dos docentes que mediarão a oferta dos itinerários formativos e a situação do alunado de ensino médio (propedêutico, integrado e normal) em relação ao fluxo e ao rendimento escolar. Como parte de uma sequência de investigações sobre o campo curricular, o estudo volta-se, particularmente, ao estado dos sistemas de ensino médio enquanto receptores de políticas de reforma.
Para a investigação, adotaram-se premissas (não exaustivas) de condições mínimas para um acesso amplo e abrangente aos preconizados itinerários formativos, conforme estabelecido pela legislação afeta, a partir de três ângulos: a infraestrutura escolar, a formação e a valorização do docente e a trajetória escolar dos alunos de ensino médio. As premissas são confrontadas com estatísticas educacionais sobre as condições correntes de oferta do ensino médio no País (com suas desagregações) e sobre o atual estágio das metas do PNE, estimadas no 4º Relatório de Monitoramento do Plano. São utilizadas as bases de dados mais recentes do Censo da Educação Básica, os indicadores educacionais do Instituto Nacional de Estudos e Pesquisas Educacionais (Inep), a Pesquisa Nacional por Amostra de Domicílios (Pnad) Contínua, bem como o corpo normativo relacionado ao corrente Plano Nacional de Educação (PNE 2014- 2024) e à reforma do ensino médio no Brasil após 2016.
Os resultados sugerem que, para além das construções normativo-curriculares, as quais, por si, não garantem o direito e a oportunidade equitativa de acesso ao conhecimento e à experiência escolar, as discussões no âmbito do novo PNE devem perpassar mecanismos de indução e fomento a políticas de promoção de condições estruturais mínimas nas escolas e de condições de trabalho e de valorização docente que respaldem, ex ante, qualquer iniciativa política no campo curricular. Nesse sentido, identifica-se a premência de um novo PNE que recupere e avance em objetivos, metas e estratégias voltados à infraestrutura das escolas de ensino médio e à valorização, à atratividade e ao respeito à carreira docente. A discussão e formulação do Plano, entende-se, reclamam a direta participação da comunidade educacional e escolar.
