Published: August 2022

Aim. To study the spectrum of variants in the PRL, PRLR, PRLHR genes in women of reproductive age with non-tumor hyperprolactinemia. Material and methods. In women with non-tumor hyperprolactinemia (n = 15), targeted high-throughput sequencing of the PRL, PRLR, and PRLHR genes was performed. The target panel of genes included coding regions and adjacent splicing sites. Results. When analyzing the PRL, PRLR, PRLHR genes, a number of rare and common variants were identified. The common variant rs1205955 was found in the PRL gene (MAF А = 0.279). For the PRLR gene, a rare variant rs185353023 was identified in the 3’UTR (MAF А/С = 0.003) and 12 common variants. For the PRLHR gene, 10 common variants have been identified. The maximum number of variants was localized in the 3’UTR region and introns. Conclusions. For the first time in Russia, targeted high-throughput sequencing of the PRL, PRLR, PRLHR genes was performed, the results of which did not reveal obvious pathological variants in the studied genes in women with high prolactin content of non-tumor origin. The discovered polymorphism in these genes makes it possible to further study its association with impaired function of the prolactin link of hormonal regulation.

Background. The study of explanted heart valve bioprostheses is a valuable source of information about the destructive processes in their components that develop as a result of prolonged contact with the recipient’s body. An analysis of the morphology, staging and degree of involvement of various valve prosthesis materials in the prevalence of pathological processes – calcification, mechanical damage, growth of the connective tissue capsule, is the basis for developing potential methods for increasing the service life of these products and reducing the risk of re-interventions. The aim of the study was to evaluate the potential of computed microtomography to analyze the internal structure of a biological prosthetic heart valve explanted due to dysfunction. Material and methods. In this work, we investigated the prevalence of pathological mineralization of the PeriCor bioprosthesis, explanted as a result of the developed dysfunction of the leaflet apparatus with a clinical picture of grade 2B prosthetic insufficiency. The material was described macroscopically, after which it was subjected to high-resolution computed microtomography. In the structure of the sample, X-ray dense areas of pathological mineralization were identified and described, and the volume of the material involved in calcification was assessed. Results. It was shown that the main pathological changes that led to prosthetic dysfunction were degenerative changes in the biomaterial with signs of calcification, thickening and rupture of the leaflets. It was quantitatively determined that the areas of radiologically dense inclusions (calcifications) occupy 11.1 % of the volume of the material. It has been established that the described areas are associated with the sheathing of the frame and with the elements of the suture material used in the production of this bioprosthesis. Conclusion. The method of non-destructive analysis of the internal structure of altered materials of a biological prosthesis studied in this work has demonstrated the possibility of а qualitative and quantitative assessment of areas of pathological mineralization, their distribution and connection with other processes leading to the development of prosthetic dysfunction. The method makes it possible to visualize macro- and microsites of calcification and can become a valuable tool to complement existing approaches to the study of explanted bioprostheses.

Authors: Jahagirdar R.
Published: August 2022

There is a high risk of suicidal attempts in patients with psychiatric problems. This risk varies according to the sociodemographic status and clinical presentation. Periodic systematic profiling of suicidal risk factors in developing countries is an established need.Objectives. The objective was to study the sociodemographic data, psychiatric disorder, precipitating events, mode of attempt, and intent of attempt in suicide attempted patients.Material and methods. During the 1.5 years, 150 referrals were screened for the presence of suicide attempters in consultation-liaison services. Those who fulfilled the criteria for suicide attempters were evaluated by using semistructured pro forma containing sociodemographic data, precipitating events, mode of attempt, psychiatric diagnosis by using ICD-10 and intent of the attempt.Results. Adult age, rural background, housewives and students, unemployed, below matriculation educated were more represented in this study. Gender wise more females are represented. More than 80 % of all attempters had a psychiatric disorder. The majority had a precipitating event before the suicide attempt. The most common method of attempt was by use of insecticide poison. Many have moderate intent in the attempt.Conclusions. The majority of suicide attempt patients had a mental illness. Early identification and treatment of these disorders would have prevented morbidity and mortality associated with this.

Les briques de terre stabilisées peuvent être une bonne alternative pour résoudre le problème de logement si les typologies de sol, les horizons de prélèvement de sol et les quantités de liants bon marché comme la paille de riz sont identifiés. C’est pourquoi une étude a été réalisée sur les sols prélevés dans l’horizon B de Ferralsols et d’Acrisols ainsi qu’un échantillon de Kaolin ont été utilisés pour les fabrications d’adobe. Les briques de terre crue ont été fabriqué avec différentes proportion de paille de riz (0,2% ; 0,4% ; 0,6% ; 0,8% et 1%), et soumis à des tests de compressibilités et de flexions. Les résultats obtenus montrent que le dosage à 0,4% de paille a été optimal, avec une résistance à la compression de 1,04 - 1,2 N/mm2 pour les Ferrasols prélevés à une profondeur de (113 cm -30 m) et 0,21- 0,65N/mm2 pour les Acrisols (74 -122 cm). La proportion optimale en paille a été de 0,2% pour la flexion (0,01 - 0,06N/mm2) avec une plus forte valeur de 0,06 N/mm2 pour le kaolin issu du Ferralsol plinthic justifiant cette recommandation pour une meilleure résistance à la flexion. Le Ferrasol Stagnic dosé à 0,4% de paille a été recommandé pour une meilleure résistance à la compression.
Macroeconomics Indicator, Institutional Quality, and Public Private Partnership: A Case of Indonesia
Authors: Grafitanti Iklima Devi , Ubed Roby Syaiful
Published: August 2022

Objective: This study aims to provide empirical evidence about the effect of macroeconomic conditions (inflation and GDP growth) and governance (control of corruption, stability politics, and voice and accountability) on private participation in PPP infrastructure projects in Indonesia as proxied by a total investment of PPP project.
Design/Methods/Approach: This study uses secondary data with annual data for the period 2003 to 2019. The data sources are obtained from the World Bank Database (WGI, WDI, and PPI).
Findings: The results show that inflation, GDP growth, and stability politic have no significant effect on the total investment of the PPP in Indonesia. Meanwhile, control of corruption has a significant positive effect on the total investment of PPP, and voice and accountability have a significant negative effect on the total investment of PPP projects in Indonesia.
Originality: This study differs from previous research since variables such as inflation, GDP growth, political stability, corruption control, voice, and accountability have never been used in the Indonesian context.
Practical/Policy implication (optional): These findings are likely to imply government to improve corruption control so that private participation in PPP projects increases and increasingly involves citizens' participation in PPP projects.

Educational Media is a determining factor in achieving the success of the learning process, especially in e-learning. E-learning is something new for teachers in Indonesia, especially Japanese high school and vocational high school teachers in Bali. There may be problems arising in the preparation and use of educational media. Therefore, it is important to know how the teacher determines the media in Japanese e-learning and teachers' perceptions of the use of these media. To obtain answers to these questions, a purposive online survey was conducted, followed by descriptive analysis. The survey was conducted on 117 Japanese high school and vocational high school teachers in Bali. The determination of the online learning platform is based on the results of discussions between related parties in education, especially students and teachers. The selection of educational media (teaching material) is tailored to the needs of delivering materials and the student conditions. Regarding teachers' perceptions of the use of media, there are differences in terms of the criteria for the gender of the teacher and the hours of experience of the teacher. Meanwhile, in the education level criteria, there is no difference in the perception of the teacher.
