Continuous planting of Coix lacryma-jobi L. has expanded, causing yield and quality drops. A key issue is autotoxicity due to unbalanced root-microbe interactions, but this is not well understood. In this study, we hypothesized that root exudates from C. lacryma-jobi impede seed germination and young plant growth, which is exacerbated in continuous cropping systems. Autotoxicity was simulated using rhizosphere soil leachate prepared from Xingren C. lacryma-jobi cultivated for different durations to investigate the effects on seed germination and young plant growth and explore the relationship between continuous cropping and autotoxicity. Four concentrations, 0.025 (C1), 0.050 (C2), 0.100 (C3), and 0.200 g/ml (C4), and three continuous cropping years, rotation (P0), continuous cropping for 4 years (P1), and continuous cropping for 6 years (P2), were set, with distilled water as the control, totaling 13 treatments. Seed germination and young plant growth tests were conducted. The results showed that the rhizosphere soil leachate significantly affected seed germination and young plant growth depending on continuous cropping years and leachate concentration. The inhibitory effect of P2 at C4 was the strongest. The synthesis effect (SE) of the rhizosphere soil leachate under different continuous cropping years and concentrations was P2 < P1 < P0, C1 < C2 < C3 < C4. The research results reveal key factors contributing to continuous cropping obstacles and provide a scientific basis for developing sustainable agricultural strategies. This will help increase crop yields in C. lacryma-jobi planting areas, improve soil health, and promote the development of more resilient agricultural systems.

Reliable estimation of mango fruit maturity has great significance in ensuring enhanced fruit quality, shelf life and market value. There is hardly any univocal criterion that can be used to correctly detect the optimum stage of fruit harvest under varied climatic conditions. Hence an experiment was conducted to optimize a reliable criterion for one of the most important commercial mango varieties of India (‘Dashehri’) under sub-tropical region. Fruits were harvested progressively in five pickings viz. 90, 95, 100, 105 and 110 days after full bloom (DAFB). Heat unit, fruit firmness, dry matter, soluble solids content and SSC/acid ratio were considered as stable attributes in defining maturation due to their low standard deviation and coefficient of variation. Harvesting of ‘Dashehri’ mango between 95-100 DAFB exhibited enhanced color development (a* and b*), fruit quality and sensory attributes with no incidence of jelly seed. On the other hand, late harvesting of fruits not only caused high incidence of jelly seed but also affected the shelf life. The findings were also evident with principal component analysis. Early harvested fruits were characterized with sub-optimal color attributes, high post-harvest weight loss and low SSC, sugar and ꞵ-carotene content. The results indicated that DAFB can be used as a reliable non-destructive index to predict optimum time of fruit harvest. Accordingly, optimal range of SSC, dry matter, firmness, heat unit accumulation and SSC/acid ratio was quantified at maturation under subtropical climatic conditions of north India.
Viticulture in Santorini Island: current trends and challenges
Authors: XYRAFIS Efstratios G.
Published: December 2024

The Santorini vineyard is a unique and extreme vineyard on a global scale with economic, historical and wine value. It also constitutes the second largest activity after tourism although linked to it. The special soil-climatic conditions and the specificity of viticulture on the island make it uniquely distinct and therefore a field of interdisciplinary study and research at a local and global level. However, the aging of the vineyard, the reduction of its cultivation area, its non-optimal management and finally the looming effects of climate change form a set of factors that should be weighed and assessed by those involved in the sector. At the same time, the rapid changes taking place at the global level (e.g. technological innovations) create opportunities, but at the same time the context in which the brand name "Santorini" is undoubtedly part of becomes more competitive, while also entailing risks from unforeseen developments. Only with collective action and a strategic approach will it be possible to ensure a sustainable future for the vineyard of Santorini. It is up, the stakeholders of the island to take the adequate initiatives.

Published: December 2024

This paper aimed to monitor the adaptation of one-year black locust seedlings in the field conditions. The seedlings of three Romanian provenances were previously produced in the containerized method under eight different substrate conditions (peat MKS 1, peat MKS 3, rendzina, rendzina + sand, dystric cambisol, dystric cambisol + sand, eutric cambisol and eutric cambisol + sand), and three water regimes (70%, 50% and 30%). The survival rate of seedlings and the main growth traits at the end of the first year after planting in the field were evaluated according to each type of treatment in which the seedlings were previously produced in containers. In field conditions, the growing traits of seedlings were not influenced by their provenance. The seedlings that were produced in the greenhouse in eutric cambisol + sand substrate, regardless of the water regime and provenance, were the shortest in the field conditions. The highest values of height were registered for the seedlings produced in peat MKS3 substrate under a medium watering regime. The seedlings that were produced in containers on dystric cambisol with sand substrate under high and medium water regimes had the best response in terms of survival in the field.

Time to initiation of dialysis and length of stay in hospitalized patients with kidney damage: a cross-sectional study
Authors: Gemente Douglas Vieira , Bacci Marcelo Rodrigues
Published: December 2024

ABSTRACT BACKGROUND: Universal healthcare is a cornerstone of Brazil’s public health system. However, delayed diagnosis and treatment of chronic kidney disease (CKD) remain substantial issues. The scarcity of outpatient dialysis facilities contributes to extended hospital stays. This study aimed to examine how the time to dialysis initiation (TID) impacts mortality in patients with renal disease. OBJECTIVES: This study aimed to evaluate the correlation between variables affecting TID and mortality in hospitalized patients with renal disease. DESIGN AND SETTING: A cross-sectional study was conducted at Santa Marcelina Hospital in São Paulo. METHODS: This cross-sectional study was conducted in a tertiary hospital, involving adults with kidney disease who were referred to the emergency department between 2014 and 2017. Primary outcomes included TID and mortality rates. RESULTS: Among the 402 patients studied, the average age was 58.6 years, and 59.4% were men. The median hospital stay was 44.5 d. Notably, 28.1% of the patients began dialysis under emergency conditions. Diabetes and hypertension were the most prevalent causes of renal disease. A positive correlation was found between age and TID (P = 0.007). CONCLUSIONS: Primary care in Brazil often fails to effectively detect and manage CKD, leading to a higher incidence of emergency dialysis, particularly among older adults. This delay correlates with increased mortality rates. Older age is associated with delayed TID, prolonged hospital stays, and consequently higher mortality. These findings highlight the need for better primary care to effectively manage CKD and reduce hospitalization and mortality.

Abstract Introduction: Multicenter research initiatives in Brazilian dialysis centers are scarce. We described the recruitment and implementation phases of the SARC-HD study, aimed at investigating sarcopenia and its impact on adverse clinical outcomes. Methods: The SARC-HD is a cohort study being conducted with patients on hemodialysis in Brazil. The recruitment phase was defined as the period from the invitation to the center until the start of patient enrollment, whereas the implementation phase lasted from then until the completion of enrollment and baseline data collection. Upon implementation, a structured questionnaire was distributed to collect feedback from principal investigators. Results: 21 centers from three Brazilian regions consented to participate, with two dropping out. Ten principal investigators oversaw the 19 sites. Nine centers (47%) were funded entirely by health insurance companies. A total of 1525 patients were screened for eligibility and 1008 were enrolled, with a 66.1% recruitment rate. Recruitment and baseline data collection took 12 [interquartile range: 5–15] weeks. Qualitative content analysis identified barriers such as a lack of infrastructure and logistics for research. Facilitators included the management and organization of the steering committee. Data collection challenges were mainly reported with the subjective 7-point global assessment and the international physical activity questionnaire. The main challenge for the ongoing maintenance phase will be the lack of standardized information in electronic health records. Conclusions: The recruitment and implementation phases of the multicenter SARC-HD study were feasible. Barriers and facilitators identified by principal investigators may help future multicenter initiatives to integrate research-related tasks into clinical routine, facilitating successful experiences.

Abstract Background: A new induction therapy strategy of a single 3 mg/kg dose of rabbit antithymocyte globulin (r-ATG) showed a lower incidence of acute rejection. Methods: The objective of this study was to use real-world data to determine the incremental cost-effectiveness ratio (ICER) of r-ATG induction for the prevention of acute rejection (AR) in the first year following kidney transplantation and for kidney graft survival over 1, 4, and 10 years of post-transplantation from the perspective of the national public healthcare system. A Markov state transition model was developed utilizing real-world data extracted from medical invoices from a single center. The study population consisted of adults at low immunological risk undergoing their initial transplantation and received kidneys from either living or deceased donors. The intervention of r-ATG induction was compared to no induction. The clinical outcomes considered for this analysis were acute rejection, cytomegalovirus infection/disease, death, graft loss, and retransplantation. Results: The cost-effectiveness analysis in the first year revealed that the r-ATG group was more cost-effective, with an ICER of US$ 399.96 per avoided AR episode, an effectiveness gain of 0.01 year in graft survival and a total incremental cost of US$ 147.50. The 4- and 10-year analyses revealed an effectiveness gain of 0.06 and 0.16 years in graft survival in the r-ATG induction group, and a total incremental cost of US$ −321.68 and US$ −2,440.62, respectively. Conclusion: The single 3 mg/kg dose of r-ATG is cost-effective in preventing acute rejection episodes and dominant in the long term of transplantation, conferring survival gain.

Abstract ZnO and Cu-doped ZnO nanoparticles (NPs) are synthesized using a biosynthesis process utilizing Aloe barbadensis (Aloe vera) leaf extract. The investigation thoroughly explores the structural, morphological, antibacterial, optical, and photocatalytic properties exhibited by ZnO and Cu-ZnO NPs. Both NPs formed a hexagonal wurtzite phase, and the crystallite sizes of ZnO and Cu-ZnO NPs are 21.28 nm and 17.55 nm, respectively. From the morphology, it has been observed that the particle size of Cu-ZnO is 15-20 nm whereas it is 20-50 nm for undoped ZnO. The antibacterial assessment was conducted through the agar well diffusion method, employing Klebsiella pneumonia, Escherichia coli, and Bacillus zhangzhownsis bacterial mediums. The highest bacterial growth inhibition observed for Cu-ZnO against Klebsiella pneumonia is 21 mm, 35% higher than undoped ZnO. It is found that the band gap for Cu-ZnO (3.22 eV) has reduced compared to the band gap of undoped ZnO (3.37 eV). The photocatalytic capabilities of both nanoparticles were evaluated through the degradation assessment of Methylene Blue (MB) dye and natural blackberry dye. Nevertheless, improved photocatalytic activities were observed in Cu-ZnO nanoparticles (the highest value is 83.4%) compared to the un-doped ZnO.
Environmental impact of real precast and cast-in-situ supermarket building structures
Authors: Dal Lago Bruno , Krelani Visar , Visconti Davide
Published: December 2024

Alongside the efforts focusing at material level to mitigate the environmental impact of constructions, another instrument is reduction of material volume employed by structural optimisation, often ensured by innovative technologies employing high-performance materials that typically have, assuming same material volume, higher impact than traditional ones. The present paper compares the environmental impact of two similar single-storey supermarket facilities designed and built in near areas of the Po valley, Northern Italy, with either precast or cast-in-situ concrete. Analysing the bill of materials employed for the uncladded superstructure of both buildings, the comparison based on several environmental impact indexes derived from EPDs, computed per covered square metre, allows to evaluate and compare the impact of the two structural solutions concerning the use of raw materials. Despite using materials with higher footprint, the precast solution allows a global reduction of all the environmental indexes, equal to 44% in terms of GWP, thanks to the structural optimisation allowed by such materials used in combination with advanced batching and moulding technologies. The theoretical replacement of most impacting components with alternative more sustainable solutions shows single improvements of 13∼20%, which despite being relevant, is less effective than structural optimisation in tackling a consistent reduction of impact.

Published: December 2024

This article explores the problem of defining and distinguishing between the concepts of human and posthuman, analyzes the attributes and aspects ascribed to them from the perspective of technological posthumanism. The author connects the relevance of this study with the active development of NBIC technologies, with the expectation that humanity will soon reach the point of technological singularity, and with the implications of the theory of integrated information developed by J. Tononi. The study refers to the integrated information theory, which develops the concept of the completeness of phenomenal experience and ways of its empirical fixation both in humans and in other entities, as well as to the theories of R. Kurzweil and R. Braidotti. As a result of research conducted, the paper provides the following definitions of human and posthuman subjects based on the functional approach to the definition of a human being by R. Kurzweil: a human subject is a biological or non-biological entity of natural or artificial origin, possessing consciousness or the potential for its actualization, and capable of performing the function of a subject associated with civilization; a posthuman subject is a man-made, active, intellectual agent that is benevolent to life, possesses the form of reflection of reality that is superior to consciousness, and has motives for activity that lie in the material world. The author suggests that the criterion for the diversification of such subjects is the parameter of the completeness of phenomenal experience. The existence of human subjects is associated with a certain degree of manifestation of internal and external causality, as well as with various risks for the existence of life in general; the existence of posthuman subjects is associated with the overcoming of such limitations and of existential risks for life in the universe. The results obtained are proposed for use in social philosophy and social theory.

The formation of double composite structure allows to increase significantly the fracture toughness of ceramic composites in comparison with the structure with homogeneous distribution of components. The increase in fracture toughness in samples with a double composite structure is explained by the simultaneous realization of several mechanisms aimed at crack bifurcation and dissipation of its energy, namely, the formation of elastic microstress fields and crack deflection at contact with interphase boundaries.

The paper presents a theoretical explanation of the phenomenon of anode-directed acceleration of ions in geometrically inhomogeneous vacuum diodes. The explanation is based on solving the equations of collisionless physical kinetics of electrons and ions using the example of an axisymmetric vacuum diode. The proposed theoretical interpretation demonstrates that the main mechanism of the cathode plasma expansion is the collisionless movement of ions in a self-consistent electric field. The paper also shows the possibility of the emergence of ions with “abnormally high” kinetic energies.

The temperature dependences of dielectric and thermal properties for a nanocomposite based on the organic ferroelectric diisopropylammonium iodide (DIPAI) embedded in the pores of SBA-15 silicate matrices were studied in comparison with bulk DIPAI samples. It was found that in bulk DIPAI, regardless of the temperature history, one phase transition is observed upon heating without the appearance of a ferroelectric phase. For nanocomposite DIPAI, the ferroelectric phase appears already during the first pass in the range of 362-378 K.
Studies of Sino-Indian relations from a regional perspective in the PRC: Historiography in the 21st century
Authors:   Tomsk State University, Qimou Li , Savkovich Yevgeni V. ,   Tomsk State University
Published: December 2024

The article provides an overview of the history of formation of research on Sino-Indian relations in People’s
Republic of China. The purpose of this article is to identify major thematic layers of research on Sino-Indian relations in their "common peripheries" such as South Asia, Central Asia and East Asia. The major stages of Chinese scholars studying SinoIndian relations at the regional level were divided. The nature of relations between China and India was defined. Special attention has been paid to Sino-Indian relations within the framework of various international organizations and mechanisms.
The source base of the study is attainable Chinese literature, including articles in Chinese Core Journals entering the CSSCI and A Guide to the Core Journal of China, PhD dissertations and monographs. The initial phase of the study was from the mid-2000s to 2012 – the beginning and slow development of Chinese research on Sino-Indian relations in their "common peripheries". At this stage several regional strategies were developed or formed in India, including the development of the SAARC, the implementation of the Look East strategy, and the realization of the importance of Central Asia in India's foreign policy. In this period, research of Chinese scholars was limited to the strategic policies, economic and trade ties of China and India with different regions in Asia, as well as analyzing the impact of the regional presence of one of the two countries on the other. This stage is characterized by a shift in research focus from Sino-Indian bilateral relations to the regional dimension and the beginning of comparative research on the issues.
Since 2013, the quantity and quality of Chinese research on the regional dimension of Sino-Indian relations have increased sharply; moreover, the diversification of topics and methodology is clearly observed. This phase is marked by the launch of China's full-scale Belt and Road Initiative in 2013. Immediately thereafter, multilateral frameworks for regional cooperation such as Project Mausam and Act East were launched from the Indian side, signaling a further broadening and deepening of China-India engagement in regions.
It is found that the study of Chinese scholars is not fully systematized; moreover, most of the works are characterized by such problems as a high degree of homogeneity and insufficiently grounded analytical framework in the first phase. However, the quality of Chinese academic work has gradually improved over time, with research topics becoming more diverse and theoretical and methodological frameworks better developed.
The Babenberg "Austrian Freedom" in Habsburg empire historical memory: the case of "Austrian Plutarch" by Joseph von Hormayr
Authors:   Northern Arctic Federal University named after M.V. Lomonosov, Ragozin German S.
Published: December 2024

The paper deals with the reception of “Austrian Freedom” emergence in the Middle Ages as an element of historical memory in the Habsburg empire in early XIX century. The Romanticist historiography tapped into revisiting the ideological grounds of Habsburg Empire, which took place after collapse of the Holy Roman Empire. Creating the Austrian empire in 1804 has become an impulse for producing the new historical memory to justify its legitimacy. It was Joseph von Hormayr to initiate the process during the Napoleonic warfare as a conservative ideologist and romanticist historian.
The purpose of the paper is to analyze the elements of the “Austrian Freedom” myth presented in essays on Babenberg dynasty in “Austrian Plutarch” by Joseph von Hormayr. The twenty-volume work aimed to present the main historical figures of the Habsburg empire, both Austro-German and non-Germanic. Besides the Habsburgs, “Plutarch” also contained essays devoted to Czech and Hungarian regents, ministers, warlords, artists and scientists from all parts of the Empire. The essays published in volumes 19 and 20 of the “Plutarch” dealing with the Babenberg era in Austria were the last part of the work.
The main methodology is the history of concepts, which is aimed to analyze the emergence and evolution of a certain term and its revisiting within a surrounding context. It should trace the elements of the “Austrian Freedom” as a pattern of Austrian historical memory and identity. Moreover, the concepts of imaginary community, historical myth and historical memory should ensure the study of "Austrian freedom" and its justification by Hormayr. The latest essays of the "Austrian Plutarch" were aimed at justifying the "Austrian Freedom" by means of historical memory. Narratives on the Babenberg era in Austria were to show succession to the Habsburg house as a proof for a single historical mission of Ostmark – Austria. The image of Austria was given as a state with “independence, rapid economic development and loyalty to the Christian cause” and as an adequate example of centralization for the rest of Germany. Hormayr made a special emphasis on the ability of Austria to respond towards such challenges as hostile invasions and political instability of the Holy Roman Empire. The image of the “loyal vassal of the Emperor” turned into justification of the Austrian autonomy, which was to enforce the Empire, and the Babenbergs became a personal image for it in the “Austrian Plutarch”.
The fate of the Empress Maria Feodorovna photographic collections in the 1920s–1930s. Based on documents from the Saint Petersburg archives

The family of the Emperor Alexander III was into photographic process and had a huge photographic collection. The collections of the Empress Maria Feodorovna by the time of the February revolution of 1917 numbered several tens of thousands of images. The main part of them was stored in two places: in the Anichkov Palace in St. Petersburg and in the Gatchina Palace in the suburb. The purpose of the research is to trace some ways of moving these photographic collections. The article is based on materials from the archives of St. Petersburg (Literature and Arts Central State Archive of St. Petersburg, the archive of Gatchina State Museum-Reserve and the archive of The State Hermitage).
The first museum curators tried to keep the interiors of the palaces-museums intact. The abundance of photographs in these interiors played a large role in the characterization of the last emperors. The private rooms of the Anichkov Palace, which became part of the City Museum in October 1918, and the Imperial chambers of the Gatchina Palace remained intact. In 1923, two laws were issued: "On the concentration in the Central archive of the RSFSR archives of the active leaders of the counterrevolution, as well as persons who emigrated abroad since 1917", and "On the concentration in the Central archive of the RSFSR archives of the Romanov family and some other persons". They obliged museums to hand over their existing Imperial documents and photographs to the archives. Although the first seizure of documents from the Gatchina Palace was carried out in the spring of 1917, this process has accelerated since 1923. It was a long process, which was delayed for 10 years. Nevertheless, a significant part of the photographs continued to be displayed in museums throughout the 1920s and 1930s.
In the 1920s, the curators several times sealed the Royal documents and photos from the Anichkov Palace, but we do not know if they planned to transfer them somewhere and if they did it. When the historic premises of the Anichkovo Palace were destroyed in 1927-28, the majority of the photographs were transferred to the Gatchina Palace Museum instead of the archive as required by the 1923 decrees.
The removal of photographs as parts of the Imperial archives was delayed for the first decade of Soviet power, because curators did not know their huge collection well. Photos were discovered gradually, during the inventory of the museum property, and when they were discovered, some of them were handed over to the archive. Archivists were mainly interested in documents, and photos were taken together (and at the same time) with documents. "Imperial" photographs were well represented in exhibitions and were not considered as "harmful" material, so they were not prohibited.

The aim of this research is to study the features of the rural settlement life space organization as well as the system of internal and external interaction of the peasant community with the natural, social and socio-cultural environment. The research relies on an anthropological approach. Also, the analysis of formation of organizationalplanning and functional structures of rural settlements is used.
Within the framework of a major scientific problem of territorial organization of population and economy, it is relevant to consider the specifics of this process into the borders of Tyumen district of Tobolsk province. Tyumen district is located at the junction of two natural and climatic zones of the Trans-Urals - the middle forest-steppe and southern sub-taiga, which, in turn, influenced the development of the structure of productive forces as well as land use practices. The study relies on the massive bulk of unique cartographic archival materials of the General Land Survey in the Tyumen district of the Tobolsk province of the 19th century from the fund of the GBUTO GATO, No. 49. It is planned to present these archival sources for the first time in scientific discourse. The plans of the villages under analysis are not classified and are publicly available.
The documentary basis for drawing up plans for rural settlements was formed by topographic surveys of the Corps of Military Topographers and other departments of the Russian Imperial Army. The archival materials show that in the process of the land surveying, which was carried out from 1800 to 1880, with the aim of forming a reserve land fund “State quitrent articles”, the interests of Russian old-timers, descendants of the first wave of settlers at the beginning of the 17th century, were significantly affected. The practice of the borrowed-tribal form of land ownership was preserved, which is a historical phenomenon, existed exclusively on the territory of the middle Trans-Urals in the 19th century.
Integration of written and archaeological sources on the history of the Umrevinsky ostrog (Novosibirsk region)

Published: December 2024

The archeological research related to the period of the Russian development of Siberia and the Far East (the end of the 16th - 17th centuries) takes a special place in the archeology of the Asian part of Russia due to the fact that this era is quite rich in written sources. During interpretation of the materials of archeological research, it is required to review them jointly with the data obtained from historical sources. The goal of the research, the progress and the results of which are described in this article, is to integrate archeological and written sources for reconstructing the history of the Umrevinsky Ostrog. The source base of the research is represented by the materials of the Umrevinsky Ostrog archeological excavations, scarce archive data disseminated across various scientific publications and itineraries by I.G. Gmelin, D.G. Messerschmidt, and S.L. Vladislavich-Ragusinsky. The article dwells upon the time of the Umrevinsky Ostrog foundation, the construction periods are identified. The original fortifications had disappeared by 1725. In 1732-1734, the ostrog was built again, with two towers added to it. In 1741-1759, the ostrog lost its defensive functions, and there was a necropolis formed in its territory. By the mid 1780s, the large industrial settlement that existed by the ostrog fell apart. The experience in assessing the information potential of archeological and written sources through the lens of historical and archeological characteristics of the Umrevinsky Ostrog that is presented in this article allows outlining three ways of integration of the stated types of sources by conducting a complex study of the "ostrog"-type monument: 1) isolated integration of written and archeological sources when data from heterogeneous sources do not overlap in terms of their content but follow consecutively one another, in the chronological order, by reconstruction of the monument history; 2) correlation of written and archeological sources when data from heterogeneous sources reflect the same facts and phenomena of the past; whereby every source of any particular type has no characteristics that would be missing in the source of another type; 3) productive integration of archeological and written sources resulting in new knowledge of the past that is not a simple sum of data from archeological and written sources (isolated integration). Most frequently, in practice, the researcher comes across isolated integration but not correlation. The facts of productive integration as part of this study are very few however they are the most valuable as the so-reconstructed facts and phenomena of the past are not directly contained in archeological and written sources. The facts and phenomena of historical reality resulting from productive integration may become a source base for new instances of productive integration, which will considerably contribute to our image of facts and phenomena of the past.
Ahura’dan Kalanlar: Ağrı Dağı’nda Yok Olan Bir Köyün Etnografik İzleri
Authors: Yulu Adem
Published: December 2024

Ağrı Dağı, doğal, kültürel ve tarihsel yönüyle yerküre üzerinde en çok bilinen dağlardan biridir. Bu görkemli dağın kuzey yamaçlarında derin bir vadide kurulan ve köklü bir tarihsel geçmişe sahip olan Ahura köyü (şimdiki adı Yenidoğan köyü), tarih boyunca farklı yüzyıllarda Ağrı Dağı’nı ziyaret eden seyyahların, bilim insanlarının ve misyonerlerin uğrak yeriydi. Nuh peygamber ve çocuklarının buradan dünyaya yayıldığı inancı nedeniyle zamanla “kutsal mitolojik” bir özellik kazanan köy, 19.yüzyılda Ağrı Dağı’nın kültürel coğrafyasına damgasını vurmuştu. Kuruluş tarihi, 8. yüzyıla kadar uzanan Ahura köyü, 1840’ta depremle ilişkilendirilen yıkıcı bir kütle hareketiyle yerle bir olmasına rağmen kısa bir süre sonra yeniden kurulmuş ve günümüze kadar varlığını devam ettirmiştir. Bu çalışma, etnografik yapısıyla, yerel bir doğal felaket geçmişi olan tarihi Ahura köyünün anlatılmamış hikayesini duyulur kılmayı, bu kadim köyün görünürlüğünü artırmayı, 1840’taki yok oluşu hatırlatan coğrafi risklere ve son yıllarda kronik bir sorun haline gelen göçün nedenlerine-sonuçlarına dikkat çekmeyi amaçlamaktadır. 2022-2024 yılları arasında gerçekleştirilen saha çalışmaları ve mülakatlara dayanan bu çalışma, Ahura köyünün yerel köy sakinlerinin hafıza mekânına dönüştüğünü, yerel dezavantajlara ve coğrafi risklere rağmen belirli bir yaş üstü köy sakinlerinin yaşadıkları yere karşı bir aidiyet bağı kurduklarını ve yakın geçmişte bölgenin sosyo-ekonomik cazibesini yitirmesiyle göçün hızlandığını (özellikle gençler arasında) ortaya koymaktadır.

Breast cancer (BC) is a prevalent malignant tumor that poses a significant health risk to women. The complexity of basic BC research and clinical treatment is influenced by multiple factors, including age, fertility, hormone metabolism, molecular subtypes, and tumor grading and staging. Traditional in vitro models often fall short of meeting modern research demands, whereas organoids—an emerging 3D primary culture technology—offer a unique platform that better replicates the tumor microenvironment (TME). Coupled with advances in high-throughput sequencing technologies, organoids have become increasingly valuable in biological and chemical research. Currently, the most widely used organoid model in BC research is the patient-derived organoid (PDO) model, which is generated directly from original tumor tissues. This paper aims to summarize the current status of PDO models across various BC subtypes, highlighting recent advances in genetics, mechanisms of drug resistance, identification of new therapeutic targets, and approaches to personalized treatment. In conclusion, the development of clinical precision medicine urgently requires in vitro models capable of accurately simulating the unique molecular subtypes of patients. This review will examine the challenges and future prospects of organoid models in BC research, offering new insights into the fundamental mechanisms of BC and paving the way for more effective personalized therapies.
