Published: November 2024

Porphyry Cu deposits (PCDs) in collisional orogens are new targets for modern mineral exploration. A series of post-collisional (Miocene; 22-12Ma) porphyry copper deposit (PCDs) with Cu reserve over 45 Mt have been discovered in the Gangdese magmatic belt, southern Tibet. These magmas derived from partial melting of sulfide-bearing Tibetan juvenile lower crust are fertile for porphyry Cu in many aspects, such as high oxidation state, and rich volatiles such as water, S, and Cl, but some of individual plutons ended up with economic concentrations. The fundamental question remains what accounts for the significant Cu endowments. We measured the igneous zircon water contents of ore-related and barren high Sr/Y magmas in the Gangdese belt, southern Tibet and found that magmas that produce giant PCDs have lower zircon water contents than barren and small-deposit related magmas. Combined with previous fluid inclusions, magmatic breccias, apatite geochemistry, and thermal histories, which demonstrated higher initial water content in causative porphyries such as giant deposits of Qulong and Jiama, we believe that the lower zircon water content may be attributed to these magmas experiencing of faster cooling and sudden depressurization of a large, primed, volatile-saturated or supersaturated mid-upper crustal magma chamber, which could lead to rapid and voluminous volatile exsolution and fluid discharge. These processes caused intense hydrothermal alteration and large ore deposition. In contrast, magmas that experienced slow cooling and deep emplacement would undergo steady state degassing and weak alteration. The variable intrusive and thermal histories across Gangdese reflects interplay between surface and lithospheric dynamics within the Himalaya—Tibet orogen. Our findings suggest the difference of zircon water content reflects the emplacement rate and depth of granitic body, and therefore may serve as an indicator for tectonics and potential for mineralization.
Porphyry Cu-Mo mineralization at Anabama Hill, Delamerian Orogen, South Australia: Fertility assessment implicated from epidote and chlorite chemistry

Published: November 2024

Porphyry-style hydrothermal alteration has long been recognized in the Delamerian Orogen, Southeastern Australia. However, the fertility of porphyry prospects in this belt, including the Anabama Hill, remains elusive, due to intermittent exploration activities and sparse exposure. Recent significant discoveries of porphyry-epithermal Cu-Au deposits in the adjacent Stavely Arc have led to renewed exploration interest. Reinvestigation of the Anabama Hill drill cores highlights that K-feldspar-rich and epidote-chlorite-dominated alterations are superimposed by extensive quartz-pyrite ± chalcopyrite ± molybdenite veins with white mica-quartz selvedges, related to early-middle Ordovician granitic stocks. Granodiorite and diorite hosts have diagnostic geochemical characteristics, including high Sr/Y, V/Sc ratios, and listric-shaped REE trends, implying amphibole-leading fractionation due to high water contents in primitive melts. LA-ICP-MS analyses show that characteristic element compositions, e.g., high Fe, Sr, Pb, U and Bi and low Mg and REEs in the Anabama Hill epidote, and high Mn, Zn, Zr and U and low Ca, Ba and Pb in the chlorite, suggest the two minerals resulting from propylitic alteration rather than metamorphism. Compared to well-mineralized porphyry deposits, the epidote shows high Bi, Cu, Sr, Ti, Zr and U, and the chlorite is high in Ti/Sr and Al/Si ratios, implying that they are most likely deposit-proximal or near a heat center. This is supported by intermediate to high temperatures of 200—420°C calculated by chlorite geothermometer. Propylitic epidote and chlorite outside pyrite halos typically define geochemical shoulders by anomalous As-Sb and Mn-Zn highs, 1—1.5 km away from the mineralized centers. Given most of the epidote and chlorite intergrown with sulfides, their close proximity to a likely mineralized center accounts for low to moderate concentrations of distal pathfinder elements and subdued performances on the As-Sb and Mn-Zn fertility plots. Combined with bulk-rock results, proximal-fertility indicators recorded in epidote and chlorite provide encouraging implications for porphyry exploration in the Delamerian belt.
Impact of integrated marketing communication strategies on choice of higher education institutions
Authors: Roy Saumi , Misra Sheelan
Published: November 2024

In today’s fiercely competitive realm of higher education, Integrated Marketing Communications (IMC) have emerged as a crucial approach for institutions to effectively connect with prospective students. This study examines the influence of IMC strategies on students’ choices of higher education institutions (HEIs) in Bangalore, India. Using a descriptive research design, data were gathered via a structured questionnaire from a sample of 384 students. The findings reveal notable disparities in perceptions of IMC based on gender, academic discipline preference, and institution type. Interestingly, age does not yield significant differences in IMC perceptions. A positive correlation (0.632) between IMC perceptions and choice of HEIs underscores the importance of customized strategies in attracting and engaging students. IMC strategies such as digital marketing, social media engagement, content marketing, alumni engagement, and student ambassadors significantly influence the choice of HEIs with the variance of 0.315, 0.523, 0.394, 0.619, and 0.298, respectively. Further, IMC strategies such as digital marketing, social media engagement, alumni engagement, partnership with influencers, and student ambassadors significantly influence the selection of disciplines with the variance of 0.298, 0.642, 0.497, 0.421, and 0.234, respectively. In essence, this study emphasizes the pivotal role of effective IMC strategies in higher education choice decision-making and provides actionable insights for institutions seeking to refine their marketing approaches.
Stress state and strength of welded joints with V-shaped elements
Authors: Gumerov Aidar , Vafin Tagir , Sokolova Viktoria
Published: November 2024

It has been established that in the vicinity of V-shaped elements with a sharp apex, the stress field has a singularity of type σ→∞, which requires the use of the concept of “stress intensity factor” in strength calculations. This need arose due to different dimensions of the SIF and fracture toughness. Special criteria for the destruction of structures with V-shaped stress concentrators have been developed, which include, as special cases, the criteria of classical mechanics and the criteria of fracture mechanics. An experimental test of the proposed criteria and calculation methods was carried out. The information obtained is useful for analyzing welded joints on main pipelines and other equipment.

Published: November 2024

Within the framework of Kirchhoff’s theory, a new approach to constructing a solution to the problem of modeling the bending of a thin rectangular orthotropic plate clamped along the contour, which is under the influence of a load normally distributed over its surface, is proposed. the solution to the inhomogeneous biharmonic equation for an orthotropic plate is obtained in the form of a partial sum of a double series in Chebyshev polynomials of the first kind. To find the coefficients in this expansion, the boundary value problem is reduced by the collocation method to a system of linear algebraic equations in matrix form using the properties of these polynomials. Based on matrix and differential transformations, expressions for bending moments and shearing forces are obtained. the results of calculations of the bending of the middle surface of the plate under different loads on the plate are presented, which demonstrate the effectiveness of the proposed approach.
Common fixed point results: New developments on commuting mappings and application in dynamic programming
Authors:   University Sidi Mohamed Ben Abdellah, Touail Youssef
Published: November 2024

Based on a class of semicontinuous functions, we prove a common fixed point theorem for a pair of commuting mappings. As a consequence, we give another common fixed point for the so-called weakly contractive mappings of type ET. The proven results are established in the setting of bounded metric spaces without using neither the compactness nor the uniform convexity. Some examples are built to demonstrate the superiority of the obtained results compared to the existing ones in the literature. Furthermore, an application to a system of functional equations arising in dynamic programming is given.

Zipf’s law have been shown to hold true in many places. From it’s first idea of a statistical phenomenon related to natural language to it’s later adaptations for economical, social and many other fields, it has been shown to work almost universally. In all of these cases authors discuss the applicability of the Zipf’s law in terms of semantically complex structures. We take this notion a step further and show how this law can work for data analysis, in particular for the sequences of byte data, obtained from various sources. We show that, using the basic chunking methodology, the Zipf’s law can be shown to hold true for many different types of raw sequences of byte data. In particular, the law holds true in all cases for the “middle point” of data, where it is present with a degree of certainty of more than 90 %. We conclude by discussing the implications and potential use cases of these findings.
On the boundary control problem for a pseudo-parabolic equation with involution
Authors:   Namangan State University, Dekhkonov Farrukh N.
Published: November 2024

Previously, some control problems for the pseudo-parabolic equation independent of involution were considered. In this paper, we consider a boundary control problem associated with a pseudo-parabolic equation with involution in a bounded one-dimensional domain. On the part of the border of the considered domain, the value of the solution with control function is given. Restrictions on the control are given in such a way that the average value of the solution in the considered domain gets a given value. The problem given by the method of separation of variables is reduced to the Volterra integral equation of the second kind. The existence of the control function was proved by the Laplace transform method.
The Military Component and its Role in the History of the Japanese State and Society: The Specifics of the Japanese Military System in the 7th–9th Centuries
Authors:   St. Petersburg State University, Osmanov Evgenii M.
Published: November 2024

The purpose of this article is to analyze the role of the military component underlying the functioning of the Japanese state in the 7th–9th centuries. It was during this period that military houses appeared in Japan, and military service began to be perceived as one of the most important government functions. The recruitment of the armed forces was based on universal conscription. As part of the most important government codes, the Military Defense Law for the first time in Japan laid the foundation for the formation of the institution of universal conscription. In this regard, it is extremely interesting to trace how much the Japanese recruitment system coincided and whether it coincided at all with the Chinese one. Created at the turn of the 7th–8th centuries the army recruitment system was a complex phenomenon, which was undoubtedly a progressive step towards the formation and development of the Japanese state. However, despite all the progressiveness of this system, which was borrowed by the Japanese from China, in the conditions of Japanese reality (exorbitant burden for peasants and the absence of enemies) it turned out to be unnecessary and by the 9th century it was replaced by “private” formations. However, the fact that this system, with minimal changes, was taken as the basis of the Japanese Imperial Army in the second half of the 19th century and existed until 1945, speaks of its advanced character and enormous historical significance.
Questions of Attribution of Some Tiles from Mausoleum in Khanqah of Pir Huseyn
Authors:   State Hermitage Museum, Sadofeev Dmitry V.
Published: November 2024

The article is devoted to the study of medieval Iranian lustre tiles in the collection of the State Hermitage Museum and foreign museum collections. Previously, some tiles were published in 1946 in “Tiles from the mausoleum of Pir Huseyn” by V. A. Kratchkovskaya. V. A. Kratchkovskaya had analyzed the Hermitage collection and published tiles, concluded that some of the tiles belong to Khanqah of Pir Huseyn on the Pirsagat River in Azerbaijan. Tiles from Khanqah were completely stolen by the 1920s and now are stored in Baku, Tbilisi and St. Petersburg. The author found additional materials that made it possible to revise the position of V. A. Kratchkovskaya and to state that some of the previously published tiles could not come from the monument. The State Hermitage museum has 22 tiles from the lower part of the cenotaph — a ledge. In addition to them, the author found 14 more tiles from this group in various publications and museum collections. After combining the text on the tiles, the author came to the conclusion that V. A. Kratchkovskaya inaccurately determined the number of tiles on each tier. The author clarified dimensions of the ledge, and concluded that the dimensions of the ledge do not fit into the room where the cenotaph was located. V. A. Kratchkovskaya relied only on circumstantial evidence and had no direct confirmation of the origin of the tiles. The author identified some stylistic features uncharacteristic for tiles from Khanqah and called into question attribution of corner tiles and some luster-cobalt stars.

Authors:   Institute for Linguistic Studies of the Russian Academy of Sciences, Turanskaya Anna A.
Published: November 2024

Any specialist, engaged in the research of the South Siberian antiquities, encounters various materials and collections of Aleksander V. Adrianov (1854–1920), an outstanding researcher who carried out archaeological excavations of hundreds of anciet burial mounds, discovered the majority of currently known petroglyph locations, and dozens of stone carvings and inscriptions. For various historical reasons the materials collected by this prominent archaeologist were never presereved together at the same place. Due to the the existing at the beginning of the 20th century tradition the collected items were sorted by contents and transferred to various institutions of the Russian Academy of Sciences and other academic organizations. This article deals with a rather small part of the Aleksander V. Adrianov’s materials, i. e. the estampages made by the researcher himself and, most probably, under his supervision. These estampages were transferred to the Asiatic museum (AM, nowadays the Institute of Oriental manuscripts of the Russian Academy of sciences (IOM RAS)) in the 1920s from the Museum of Anthropology and Ethnography (now MAE RAS). The estampages were identified during the throughout inventorying and cataloguing of the Collection of Central Asia and Siberia of the IOM RAS in 2021–2023. The collection includes 95 estampages of 30 Old Turkic runiform texts from the Yenisei area, as well as three later Buddhist inscriptions, that were discovered by Adnianov in 1904–1916. The article includes a detailed information on the provenance of the estampages, identified in the Collection of the IOM RAS. and their brief catalogue.

Authors:   Urgench State University, Annakhasanova Irina B.
Published: November 2024

In the article, the issue of studying the comparative analysis of the study of the work of Alisher Navoi by European and Russian orientalists is considered. The works of scientists, given the huge source base, are distinguished by diversity, differences in approaches and interpretations. Nowadays, there are so many translations and works on the study of the works of Alisher Navoi that they require periodic systematization and analysis. From this point of view, the study of the problem of perception and interpretation of such a bright classic in oriental studies in Europe and Russia in the 20th–21st centuries is important. The need for studying the work of Alisher Navoi in European and Russian oriental studies also provided a versatile approach to the analysis of literary text. The main branch of oriental studies of the twentieth century of Russian Navoi studies is the study of works of a figurative nature. The descriptions and reviews of the works of Alisher Navoi are studied separately. The scientific skill in the research of Russian scientists of the 20th century is studied and the features of the translation of Alisher Navoi’s works, characteristic of modern translators, are highlighted. Basically, the modern period is characterized by the systematization and compilation of catalogs of existing works. The purpose of the study is to thoroughly study European and Russian Navoi studies of the 20th–21st centuries, to give a correct assessment of the creative heritage of Alisher Navoi, comparatively examining the works of European and Russian orientalists. In the course of a systematic analysis of the following research tasks, a review of the history of studying the poet’s works in Europe and Russia was made, the most significant scientific works on the work of Alisher Navoi were highlighted both in Europe and in Russia. The problems of scientific excellence in the research of European and Russian scientists of the 20th–21st centuries were studied.

Published: November 2024

The article reveals the motivic field and specificity of Kazakh camp prose. The purpose of the work is to consider the features of camp prose in Kazakh literature. The authors studied the history of the issue, the literary leitmotif, typological convergences of Russian and Kazakh literatures, and the tragic in the novel. The relevance of the study is caused by the interest of modern science in works of camp prose, which act as a model of society in a certain historical period. The scientific novelty of the study is the insufficiency of studying Kazakh camp prose in modern literature. Based on the material of Zhaik Bekturov’s novel “The Brand,” the authors prove that the image of the camp serves as the semantic center of the work. The camp gives rise to motivic connections that are repeated in the name, characters, portraits, comparisons, vocabulary, and details. The specificity of the work is the characters who have lost their individuality; they form motive connections and a single motive field of the novel. The artistic originality of the work was the perception of the camp through the prism of the national picture of the world and the repetition of the motif, which is necessary to understand the artistic idea of the work. The tragic in the novel takes on a special meaning: movement among contradictions is generated by a change in the layers of the image, where the hero’s internal value orientation remains unchanged. Finally, conclusions are presented, structural-semantic and analytical research methods were applied.
Conceptual and Meaningful Originality of the Literary Translation of the Poem Demon by M. Yu. Lermontov into the Kyrgyz Language in the Version of O. Sultanov
Authors:   Kyrgyz-Russian Slavic University named after the first President of the Russian Federation B. N. Yeltsin, Sultanova Zhypar Omorovna
Published: November 2024

M. Yu. Lermontov’s poem Demon is the most mystical and popular (including translations) work of the poet. It demonstrates the multi-layered themes and images embedded in it. The relevance of the study is marked by the fact that in the course of literary translation, the text has even more additional facets and meanings. In Kyrgyzstan, the Kyrgyz is the state language, and Russian has the status of an official one, therefore, their cooperation can reveal the entire spectrum of the socio-cultural background of the Kyrgyz audience. Its bilingualism makes the translator be even more responsible since almost every Kyrgyz reader, knowing both languages, is able to assess the quality of the translation. However, there is the little-studied interaction between the Russian and Kyrgyz languages in the framework of literary translation, which determines the novelty of this study. The problem of the research is a literary translation in the conditions of contact of unrelated languages — Russian and Kyrgyz. The purpose of the work is to identify the conceptual foundations of the Kyrgyz translation of the poem Demon by comparing it with the original work. The main objectives include the study of the features of the Kyrgyz literary translation of the Demon in the version of the People’s Poet of Kyrgyzstan Omor Sultanov. In Kyrgyz it is called Azreil. The conceptual and semantic accents of poem’s translation are of paramount importance, while the assessment of its equivalence and adequacy, as well as the degree of adaptability, are additional parameters for study.
In Reference to the Methods for Expressing Speech Contamination by Means of the Chinese Writing System (Based on Works of Fiction)

Published: November 2024

The authors put forward the hypothesis that contaminated speech can be expressed by means of the Chinese system of writing. However, as compared with alphabetic languages, its application in the Chinese language is quite limited. The objective of the study is to find methods of expressing contaminated speech by means of the Chinese hieroglyphic writing. To achieve the objective the authors set themselves a number of tasks: to study the approaches to the study contaminated speech, classifications of the phenomenon; to find and analyze the elements of contaminated speech in the Chinese fiction. In the course of the research, the authors concluded that, despite its morphological features and the writing system, speech contamination can be expressed by means of the Chinese language. The analysis of the empiric base of the research showed such methods as phonetic stylization; stylistically colored lexemes; graphic substitution of characters for 错别字 (“incorrectly written characters”) and violation of grammar and punctuation rules are used for the indication of contaminated speech. Within the framework of a work of fiction, contaminated speech works as an element of the artistic language with special linguistic and pragmatic functions, allowing the reader to form the opinion about the linguistic personality of the character.
The Geocultural Image of the Vygovsky Region in the Mikhail Prishvin’s Works: Specifics and Factors of Change
Authors:   Shanghai International Studies University, Wu Jun , Zou Luwei ,   Shenzhen MSU-BIT University
Published: November 2024

In the article the authors analyze the geocultural image of the Vygovsky region, its transformation in the works by Mikhail M. Prishvin in his early books “In the Land of Fearless Birds”, “Behind the Magic Bun” and in the final novel “Tsar’s Road”. In the first works, the idea of the unique geocultural space in the region is presented through acquaintance with the life style, cultural traditions, values and worldview of people who were born and live in this region all their lives. In the fairy tale novel “Tsar’s Road”, in contrast to the earlier works, deep philosophical reflections on the meaning of Russian history are added to Prishvin’s impression of the special natural and human “content” in the region, so the deciphering of an autonomous geocultural image, a unique complex subculture becomes the context for the writer to comprehend the multi-layered cultural, historical and socio-political space of the Russian North and Russia as a whole. The traditional contradiction of “necessity” and “freedom”, as a result of collision between state power and the original Russian people, according to the writer, on the territory of the Russian North has its own features and gives rise to other forms of compromise. The authors of the article explore these attributes of the transformation of cultural space in specific historical circumstances, its connection with geographical, political and socio-economic conditions, in the way Prishvin saw it, with the aim of further extrapolating conclusions to the historical and modern realities of Russian peoples. Views of Prishvin, which were not objectively assessed during the writer’s lifetime, today again attract the attention of the thinking part of humanity, since they raise to a very high level the problems of preserving the uniquenessof not only the natural-cultural system of the Russian North, but also of any ethnocultural subject.

The basic principles of working with the group are shown by the example of a discussion-dispute on the popular topic of “Professional burnout in the age of online learning”. Within the framework of the lesson, several stages are highlighted, their features are described in a similar way, the functional and semantic types of speech are indicated, which are being worked on at each stage (explanation, argumentation, instructions). It describes the part of the functionality of the MS Teams online platform that best meets the tasks of working with a foreign audience, and provides examples of effective use of such tools. Different options for structuring each stage of the lesson are considered. The educational potential of role-playing games is demonstrated, and scenarios for their construction of varying degrees of complexity are proposed. The article is applied in nature and aims to disseminate the experience of effective teaching of the creation of a reasoning text by the example of working with foreign students who speak Russian at the B1+ level, as part of ethnically mixed groups. The work is based on a textual typology developed by the staff of the Department of Russian Language and Teaching Methods of St. Petersburg State University by K. A. Rogova, D. V. Kolesova, T. I. Popova, O. V. Khorokhordina, N. V. Shkurina, I. M. Voznesenskaya and I. A. Gonchar and is implemented within the framework of a communicative activity approach. The authors propose to the teaching community another way of teaching the functional and semantic types of speech using modern technical education and achievements of methodological science.

The article highlights the main stages of history and the current state of studying and teaching the Russian language at one of the oldest departments of the Herzen State Pedagogical University of Russia. In 2018, the department celebrated its 100th anniversary. When the Philological Faculty was emerged at the Herzen Institute, the best academic traditions of Russian studies and philology of the early 20th century intersected there, and it determined the prospects for scholarly research of the Russian Language Department for a long time. The history of the Russian language and Slavic studies, dialectology and lexicography became the main scholarly directions of the department, where outstanding linguists and lexicographers of the 20th century worked: B. A. Larin, L. P. Yakubinsky, N. P. Grinkova, F. P. Filin, V. I. Kodukhov, A. P. Evgenieva, S. G. Ilyenko, A. V. Bondarko, V. D. Chernyak and others. In the 1970s scholarly problem groups were organized, which determined the main directions of work of the department for a half a century: syntax, functional lexicology, functional grammar, the language of fiction, general theory of language. In the 1990s, the activities of the department were reformatted for the following reasons: the structure of higher education in the country and the linguistic paradigm had changed, and the faculty of the department was renewed. In the 21st century all the best traditions of the Russian language department were preserved and developed. Now we can distinguish three main areas of scholarly activity of the team: rhetoric and speech culture, syntax and text theory, lexicography.
A novel hybrid model for long-term water quality prediction with the ‘decomposition–inputs–prediction’ hierarchical optimization framework
Authors: Han Jianjun , Wang Lingling , Yao Qiwen , Zhu Dawei , Zhu Hai , Xu Jin , Hu Lihan , Yang Xu
Published: November 2024

Accurate, stable, and long-term water quality predictions are essential for water pollution warning and efficient water environment management. In this study, a hierarchical water quality prediction (HWQP) model was developed based on ‘data decomposition–predictor screening–efficient prediction’ via wavelet decomposition, Spearman correlation analysis, and long short-term memory network, respectively. The observed data from 14 stations in the Huaihe River–Hongze Lake system, including ammonia nitrogen (AN) and chemical oxygen demand (COD), were used to make long-term water quality predictions. The results suggested that, compared to existing water quality prediction models, the HWQP model has higher accuracy, with the root mean square errors of 6 and 17% for simulating AN and COD, respectively. The AN and COD concentrations will range from 0 to 1 mg/l and from 3 to 5 mg/l at 12 stations, respectively, and the COD concentrations will exceed the water quality target at Stations 4 and 5. The established model has great potential to address the challenges associated with the water environment.

Aortic root reimplantation in patients with bicuspid and tricuspid aortic valve: a systematic review
Authors: Kokorin A.V. , Aminov V.V. , Lukin O.P. , Bogachev-Prokophiev A.V.
Published: November 2024

Introduction: Valve-preserving operations are gaining popularity in the surgical treatment of aortic root aneurysms in patients with both tricuspid aortic valve (TAV) and bicuspid aortic valve (BAV). Most studies are focused on the results of valvepreserving procedures in patients with TAVs.
Objective: The study takes a comparative assessment of clinical results on aortic root reimplantation in patients with TAV and BAV.
Methods: The systematic review was accomplished according to the PRISMA 2020 criteria. Search for published papers involving comparison of the results on the valvepreserving aortic root reimplantation in patients with TAV and BAV was conducted in three main electronic databases, namely Medline [PubMed], Web of Science, and Google Scholar. The review only included studies, which involved patients of both groups, differed by the anatomy of the valve; studies based on one examination group were excluded.
Results: We revealed that 13 articles met the inclusion criteria. In total, the review involved the treatment results of 3,191 patients, of whom 608 had a BAV and 2,583 had a TAV; patients of comparison groups were similar by sex and age. In most studies, hospital mortality did not exceed 1%. Patients with BAV and TAV showed no significant differences in freedom from aortic regurgitation (AR) ≥ II and long-term survival in 5, 10, 15, and 20 years. However, certain studies noted that patients of the BAV group had a significantly higher reoperation rate than those with TAV (p = 0.026 and p = 0.002).
Conclusion: Reimplantation provides excellent survival for long-term follow-up periods with a low risk of reoperation and recurrence of aortic regurgitation in patients both with TAV and BAV.

Published: November 2024

Background:

Indole is considered the most promising scaffold for anticancer
drug design due to its high bioavailability, unique chemical properties, and broad spectrum
of pharmacological action.

Objective:

Twelve novel thiazole-containing the 5-fluoro-1,3-dihydro-2H-indol-2-one
derivatives as sunitinib analogs were designed and synthesized, and their anticancer activity
was evaluated against the NCI-60 cancer cell lines.

Method:

The thiazole-contained 5-fluoro-1,3-dihydro-2H-indol-2-one derivatives were
synthesized using Knoevenagel condensation of 1,3-thiazole-5-carboxylic acid 1. Their
anticancer activities were evaluated by NCI-60 one-dose screen assay. The molecular
docking studies were performed using AutoDock tools and the AutoDock Vina programs.
The ADMETlab 2.0 web server predicted the physicochemical properties of compounds.

Results:

Among the synthesized new 5-fluoro-2-oxindole derivatives, compound 3g demonstrated
high antitumor activity (GI>70%) against eight types of cancer: leukemia,
breast cancer, ovarian cancer, lung cancer, melanoma, CNS cancer, renal cancer, and
colon cancer. The most activity was observed against breast cancer (T-47D,
GI=96.17%), lung cancer (HOP-92, GI=95.95%), ovarian cancer (NCI/ADR-RES,
GI=95.13%), and CNS cancer (SNB-75, GI=89.91%). The molecular docking results of
compound 3g demonstrated the possibility of inhibiting VEGF2 receptors as his potential
anticancer mechanism. The physicochemical properties predicted for compounds 3f
and 3g showed positive results.

Conclusion:

Compound 3g demonstrated high in vitro NCI-60 anticancer activity
against nine cancer types and showed cell growth inhibition against leukemia, CNS, and
breast cancer at 6 - 31% higher than Sunitinib, and may represent the basis for further
modification of the thiazole-containing analogs of the anticancer drug Sunitinib.

Published: November 2024

Pyrazolic chalcone exhibits diverse therapeutic activities, including anti-inflammatory,
antioxidant, antimicrobial, antitumor, and anti-diabetic properties. Structural activity relationship
(SAR) studies play a crucial role in understanding the molecular aspects governing their biological
effects, guiding the rational design of derivatives with enhanced efficacy and reduced side effects.
This review provides an overview of pyrazolic chalcone derivatives, emphasizing their synthesis
through both conventional and green methods. In comparison, conventional synthesis methods have
been widely employed in the past for the production of pyrazolic chalcones, often relying on traditional
chemical processes that may involve the use of hazardous reagents and generate significant
waste. On the other hand, green synthesis methods, in harmony with the growing emphasis on sustainable
practices in drug discovery, offer a more environmentally friendly alternative. Green synthesis
typically involves the use of eco-friendly reagents, solvents, and energy-efficient processes,
resulting in reduced environmental impact and improved resource efficiency. Overall, pyrazolic
chalcone derivatives represent a promising class of compounds with significant potential for
therapeutic applications.

Background and Aim:

Diabetic foot ulcers (DFUs) constitute one of the most debilitating
complications of diabetes mellitus (DM). The use of topical herbal products as adjuvant agents in
wound dressing is one of the most widely used practices worldwide. The present review aimed to
provide a detailed and comprehensive systematic review focusing on randomized clinical studies and
critically analyze not only the clinical outcomes but also the methodological approaches used by
these studies.

Methods:

The present systematic review was conducted according to the Preferred Reporting Items
for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. For the extraction of relevant
studies, three databases were searched: Pubmed, Web of Science Core Collection, and Scopus
by two independent researchers.

Results:

A search of the three databases resulted in the identification of 5528 records which were
reduced to 3224 after removal of duplicates. The application of inclusion and exclusion criteria left
35 full-text articles assessed for eligibility. Finally, 13 articles were excluded and only 22 articles
were advanced to the final analysis. Most studies reported details of local ulcer management only
while others reported the additional systemic/surgical measures used for management. The present
review identified 18 botanical agents/preparations used alone or in combination with other agents as
adjuvant agents in treatment of DFUs. In most situations, these agents proved to be effective.

Conclusion:

The present review reported the methodological approaches and clinical outcomes of
botanical extracts used topically for the treatment of diabetic foot ulcers in randomized controlled
studies. These agents proved to be generally effective. However, many gaps existed in the study
designs which may limit the evidence-based value of these studies.

A Crime that Cannot be Named: Normalisation or Distortion of Incest Victims’ Narratives with #MeTooInceste
Authors: Foubert Oceane , Marinato Lola , Vallery Robin , Würschinger Quirin
Published: November 2024

In January 2021, the #MeTooInceste hashtag emerged on French-speaking Twitter, allowing victims of incest to recount their experiences and bring their narratives to light. As the private became public, many defined this movement as a “liberation of speech” (Idoiaga Mondragon, et al., 2022). An extremely taboo subject (Ambroise-Rendu, 2016; Giuliani, 2016), incestuous sexual abuse was suddenly at the heart of the public debate, with politicians and the media commenting on the movement. However, with institutionalisation comes distortion (Ehrlich, 2014). Looking at 1,122 tweets, our comparison of incest testimonies and their reactions on Twitter shows that there is distortion of the victims’ narratives on two aspects: (i) when naming the perpetrator, and (ii) when naming the act. The results show that (i) while victims do name perpetrators, reaction tweets tend to erase them, and (ii) while victims name the act specifically, reactions tend to broaden the subject and talk of sexual abuse in general. The taboo might constrain the content of victims’ testimonies, and institutionalisation distort the narratives, but this movement focused public attention on the subject and normalised at least the use of the word itself. Through this study, we wish to assess exactly how these voices are changing the discursive norm about incest.
