Published: July 2023

Dalam penelitian terdahulu, temuan arca-arca pendeta Buddha di Jawa Timur selalu diidentifikasi sebagai perwujudan Raja Kṛtanāgara . Namun, ternyata arca serupa juga terdapat di Jawa Tengah dan berasal dari masa lebih awal, sehingga menimbulkan pertanyaan apakah arca serupa juga dapat dikaitkan dengan tokoh tertentu? Tulisan ini mendiskusikan permasalahan tersebut dengan melakukan kajian kembali terhadap sejumlah arca pendeta Buddha baik di Jawa Tengah maupun di Jawa Timur. Kajian dilakukan dengan pendekatan ikonografi dan ikonologi. Hasil kajian memperlihatkan bahwa tokoh pendeta Buddha diarcakan mirip dengan tokoh Tathāgata atau Buddha, tetapi tanpa atribut khas Tathagatha yaitu ūrṇā, uṣṇīṣa, rambut ikal, serta padmāsana. Penggambaran ini dimaksudkan untuk menunjukkan sifat kemanusiaannya. Selain itu, apabila di Jawa Timur arca pendeta Buddha dapat dikaitkan dengan tokoh Kṛtanāgara , arca pendeta Buddha di Jawa Tengah hanya dapat ditafsirkan secara umum sebagai perwujudan pendeta Buddha tertinggi, guru, atau arhat, dan belum dapat diidentifikasikan dengan tokoh sejarah tertentu.

In previous research statues of Buddhist priests found in East Java are interpreted as the embodiment of King Kṛtanāgara . In fact, similar statues are also discovered in Central Java from an earlier period. This raises the question whether these statues can indeed be associated with certain historical figures? This article addresses this issue by conducting a review of several statues of Buddhist priests in Central and East Java using an iconographic and iconological approach. The study showed that a Buddhist priest would be sculpted in a form similar to the Tathāgata or Buddha figure, but without his distinctive attributes, namely ūrṇā, uṣṇīṣa, curly hair and padmāsana. This depiction is meant to show his human nature. If in East Java statues of Buddhist priests can be associated with Kṛtanāgara , then similar statues in Central Java can only be interpreted in general as the embodiment of the highest Buddhist priest, guru or arhat.

Published: July 2023

Selama masa pandemic Covid-19, penghentian kegiatan dan penutupan fasilitas telah membatasi kunjungan ke museum dan situs arkeologi. Keadaan ini sangat berdampak pada peneliti yang harus mengobservasi objek kajiannya, misalnya patung. Sebagai alternatif, foto patung yang disebarluaskan secara daring dapat menjadi solusi masalah ini. Dalam tulisan ini akan dibahas tiga hal terkait hal ini. Pertama, tinjauan terhadap kajian patung kuno di masa lalu yang menggunakan foto sebagai dasar kajian menunjukkan cara itu mampu menyediakan data dimensi bentuk yang amat berguna dalam analisis gaya dan ikonografi. Kedua, kini beberapa museum dan lembaga telah menyebarluaskan katalog digital fotografi patung Indonesia kuno, meskipun kebijakan yang diterapkan beragam.Terakhir, untuk menghadapi berbagai isu digitalisasi sumber kajian berupa fotografi perlu dilakukan kerjasama multidisiplin.

Published: July 2023

INTRODUCTION: Triple negative cancer is one of the most aggressive subtypes of breast cancer. Currently, no effective treatment methods have been proposed that would significantly affect the long-term results of treatment.OBJECTIVE: To summarize the possibilities of theranostics and nanteranostics in the visualization and elimination of malignant cells and immunosuppressive cells of the microenvironment of thriple negative breast cancer.MATERIALS AND METHODS: A search was conducted for scientific publications in the PubMed information and analytical system for 2015–2022 by keywords: «triple negative breast cancer» («triple negative breast cancer»), «signaling pathways» («signaling pathways»), «tumor microenvironment» («tumor microenvironment»), «cancer stem cells» («stem tumor cells»), «theranostics», «nanomaterials» («nanomaterials»), «nanotheranostics» («nanoteranostics»). After excluding articles devoted to the technical aspects of molecular biological research, 57 publications related to the theranostics of thrice-negative breast cancer were analyzed.RESULTS: Targets for theranostics of triple negative breast cancer are associated with tumor cells and components of the microenvironment. The article presents data on the composition and interaction between various cellular subpopulations in the tumor microenvironment, as well as on the role of cancer stem cells in its formation. State of art classifications of triple negative breast cancer and data on molecular defects associated with various subtypes are presented. Targets for theranostics associated with stem, differentiated tumor cells and components of the tumor microenvironment are described. The authors present their own data on the nature of the distribution of various subpopulations of the microenvironment, which should be taken into account when choosing the nature of the effect on the tumor. The possibilities and applications of radiopharmaceuticals and nanoparticle-based preparations developed to date have been analyzed.CONCLUSION: Triple negative breast cancer is characterized by the presence of a large number of biomarkers that can be targets for diagnostic and therapeutic drugs. It is advisable to use artificial intelligence technologies for their selection. The use of nanoparticles makes it possible to reduce toxicity and ensure the implementation of several treatment methods simultaneously.
Technological Restructuring of Economies of the Former Soviet Union: from “Destruction” to “Creation”
Authors: Boiko I. V. 
Published: July 2023

Modern geo-economic and geopolitical processes create a need to rethink the integration interaction between the republics of the former USSR, now — sovereign countries. This is due not only to the rapidly increasing instability of the global financial system, the growth of trade and economic contradictions between countries, but also to the possibility of using the previous experience of inter-republican industrial-technological and intellectual cooperation to achieve the goals of economic development.Aim and tasks. The article’s main aim is to frame the technological and economic interaction between the former republics of the USSR in the new geo-economic and geopolitical conditions.Methods. The methods applied includes empirical and statistical analysis, the use of consistency, the principles of scientific discussion, dialectical methods of cognition, such as the unity of the historical and logical, the principles of induction and deduction, the principle of the linkage between qualitative and quantitative characteristics, the unity of analysis and synthesis.Results. The article highlights the features of the trajectory of the economic development of the former Soviet republics. The main problems associated with the transition to a “free market economy”, such as declining economies, population decrease, significant external debt, “Dutch disease” and deindustrialization of the economy, are identified.Conclusion. In conclusion the need to develop a new economic policy in the countries of the former USSR is argued from the standpoint of increased instability in the external economic environment and the need to strengthen their national economies, but also by the loss of economic independence and the accumulation of problems during the period of building a “market economy”. Significant efforts are required to restore the economy of the former republics of the USSR. The strategic direction is the reindustrialization of the economy, that is, the restoration of the lost economic potential on a new industrial and technological basis. For the successful implementation of the goal of strengthening economic sovereignty, it is of great importance to unite the scientific, intellectual and educational potential of the former republics of the USSR and create a common technological space. This will inevita bly lead to the formation o f a new system of international division of labor in the post-Soviet space, which is the main feature of a market economy.

Purpose. To study the features of the clinical course of coronavirus infection (COVID-19) in people living with HIV and risk factors for adverse outcomes.Materials and methods. The study included 523 patients with a confirmed diagnosis of COVID-19 occurring against the background of HIV infection and hospitalized from March 2020 to September 2021 on the basis of the GBUZ “S.P. Botkin KIB” in St. Petersburg. Two groups were formed: 1 – receiving antiretroviral therapy (n=204), 2 – not receiving ART (n=319). A comparative analysis of the results obtained during the examination was carried out using statistical methods: Mann-Whitney (p≤0.05) and the calculation of the relative risk (RR) when comparing the probability of the outcome of the disease depending on the presence of risk factors: respiratory rate ( NPV),% lung damage, levels of CD4 and C-reactive protein (CRP) with a significance level of p≤0.05.Results. Among the patients, persons aged 30 to 49 years predominated. In 50.5% of cases, coronavirus infection proceeded in the form of acute respiratory viral infections, pneumonia was diagnosed in 49.5%, which was subsequently complicated in 22.9% by the development of acute respiratory distress syndrome or sepsis in 2.1%. Severe course of COVID-19 was observed in non-adherent to ART, with CD4 lymphocyte count (≤50 cells/µl), multimorbidity and amounted to 45%.Conclusion. A feature of the course of COVID-19 in patients with HIV/SARS-COV-2 coinfection was a high number of deaths – 21.6%. In the overall structure of causes of death, the maximum share fell on HIV infection – 58.4%, COVID-19 – 24.8%, HIV/ COVID-19 –9.7% coinfection and other causes – 7.1%. Factors associated with the development of severe forms of coronavirus infection caused by SARS-COV-2 in HIV-infected patients who were hospitalized, the combination of which can be used as a predictor of death, have been identified: respiratory rate (RR) > 20 per minute, percentage of involvement lungs> 50%, CD4 lymphocyte level <40 cells/µl, CRP>50 mg/l, presence of three or more concomitant diseases.

Aim – to evaluate the effect of direct antiviral drugs (sofosbuvir and velpatasvir) on the formation of the metabolic syndrome in patients with chronic hepatitis C with a high risk of its development 2 years after treatment.Materials and methods. 112 patients with HCV (n=112) were examined, in whom the risk of developing the metabolic syndrome was determined using a specially developed method. In 58 patients, a high risk of developing metabolic syndrome was identified. This cohort of patients was divided into two groups: group 1 (n=26) who took sofosbuvir and velpatasvir and group 2 (n=32) who did not take AVT. Patients were periodically examined and observed for 2 years. At the final stage of observation, a comparative analysis of laboratory and instrumental data was carried out in patients in two comparison groups.Results. At the start of AVT, HCV patients with a high risk of developing metabolic syndrome were found to be over-weight, moderately pronounced stage of liver fibrosis (F2 according to METAVIR), high viral load, increased transaminases, total low-density lipoprotein cholesterol, atherogenic coefficient, insulin, glucose. Two years after the etiotropic therapy in HCV patients with a high risk of developing the metabolic syndrome, normalization of blood lipid metabolism, glucose, insulin levels and a decrease in the concentration of total thyroxine were registered.Conclusion. Etiotropic therapy with direct antiviral drugs in patients with chronic hepatitis C reduces the relative risk of developing the metabolic syndrome by 6,3 times.
