Authors: Φασλή Παναγιώτα
Published: September 2024

Η εκπαίδευση των προσφύγων έχει εξελιχθεί σε σημαντικό και πιεστικό θέμα για ανθρώπους σε όλο τον κόσμο (Dryden-Peterson, 2016). H Ελλάδα έχει εξελιχθεί σε μια ασφαλή ενδιάμεση τοποθεσία όπου μπορούν να ζητήσουν οι πρόσφυγες άσυλο. Ως αποτέλεσμα, ορισμένες περιοχές της χώρας έχουν μετατραπεί σε μεταβατική προσωρινή στέγαση για τους πρόσφυγες, πριν αυτοί να ταξιδέψουν σε τελικούς προορισμούς σε άλλες χώρες της Ευρώπης (Αρβανίτης et al., 2019). Μετά την ευρωπαϊκή προσφυγική κρίση που σημειώθηκε το 2015, περισσότεροι από 850.000 πρόσφυγες έφτασαν στην Ελλάδα μέσα σε δύο χρόνια, από χώρες όπως η Συρία (56%), το Αφγανιστάν (24%), και το Ιράκ (10%) (CEAR, 2017). Δεδομένου ότι οι πρόσφυγες άρχισαν να είναι όλο και πιο παρόντες στο δημόσιο χώρο, η εκπαίδευση των προσφύγων έγινε εθνικό ζήτημα στην Ελλάδα (Αρβανίτης, 2021). Τα εκπαιδευτικά συστήματα έχουν δεχθεί μεγάλη πίεση να καλωσορίσουν και ναενσωματώσουν τα παιδιά πρόσφυγες και τις ιδιαίτερες ανάγκες τους. Προς αυτόν τον στόχο, τα εκπαιδευτικά συστήματα έχουν υιοθετήσει πολυάριθμες προσεγγίσεις, οι οποίες έχουν κυμανθεί από την ένταξη των προσφύγων στα γενικά σχολεία, έως παροχή μη τυπικής εκπαίδευσης και εκπαίδευσης σε καταυλισμούς προσφύγων(Αρβανίτης, 2021). Σκοπός της παρούσας διατριβής είναι να εξετάσει, μέσω της βιβλιογραφικής ανασκόπησης και της πρωτότυπης ποσοτικής και ποιοτικής έρευνας, την εκπαίδευση των μεταναστών και των προσφύγων συνολικά στην Ελλάδα και πώς μπορούν να υποστηριχθούν ψυχολογικά. Στόχος είναι η παροχή συστάσεων για το πώς οι ενήλικες και οι ανήλικοι πρόσφυγες και οι μετανάστες μαθητές μπορούν να λάβουν την καλύτερη δυνατή ψυχολογική υποστήριξη ώστε να μπορούν να μάθουν όσο το δυνατόν καλύτερα στη δημόσια και ιδιωτική εκπαίδευση στην Ελλάδα.
Exploring the Synergistic Potential of Pectin-Chitosan Composites for Advanced Drug Delivery and Biomedical Implant Applications: A Comprehensive Review and Future Perspectives
Authors: Alsharbaty Mohammed Hussein M. , Naji Ghassan A. , Ali Sameh S.
Published: September 2024

The polysaccharides pectin and chitosan are derived from the fruit peels and exoskeletons of crustaceans and insects, respectively. Their biocompatibility and renewability make them suitable for use in food products. The size of the swelling and degradation of these cells can be controlled using different combinations. Pectin and chitosan are useful as medication delivery systems, where they can be integrated to control the dosages and residence times of pharmaceuticals. They have a wide range of applications such as wound dressings, body fat reducers, tissue engineering agents, and drug delivery agents. Addressing teeth loss with the use of dental implants is a critical element of dental care. In most cases, healing is time-consuming and painful. As a result of adding new materials to the implant surface, the healing process would accelerate, and medications would be delivered to the implant site with greater efficiency.

Situational Model of the Narrative Text Coherence in Modern Russian
Authors: Glazkov Aleksey
Published: September 2024

The article raises the issue of formal description of narrative text coherence. Coherence, as one of the essential characteristics of discourse, requires a formal description. The study proposed to solve this problem for narrative texts using situation modelling. It is defined a set of principles allowed to construct the coherent textual group, such as optimality, motivation, stability, declared variability. Based on these principles, it was determined a set of maxims of the narrative text coherence. It is shown that a sufficient condition of coherence of narrative text is inclusion of all expressed situations in one whole, provided that the presented information is consistent. As a proof of the conclusions the analysis of the case is given: a model of situational markup and a procedure of consolidating situations into a single whole. The proposed method can be used to analyze any large narrative texts
Program „dziewięciu idei-reform” Jana Kwiecińskiego – utopijna wizja naprawy Polski i świata w przededniu II wojny światowej
Authors: Ruciński Piotr
Published: September 2024

The article contains biographical findings about Jan Kwieciński, a little known publicist and educationalist, whose profile has not been previously researched, and the characteristics of his public activity in the interwar period. The article aims to analyse the “Nine Ideas-Reforms” programme, the background of which is the socio-political realities of the Second Polish Republic. Kwieciński’s possible political affiliation is explored in this work, as in a scientific study at Central Archives of Modern Records (AAN), Warsaw, he was considered an activist of National Democracy. The primary source base consists of Kwieciński’s collection of letters kept at AAN, numerous brochures, leaflets and his selected press articles. The daring idealism of Kwieciński, who for many years tried to promote his ideas in various ways – e.g. by sending utopian reform proposals to the highest authorities of the state, including both the President and Marshal of Poland – is an interesting subject for reflection. His programme can be treated as both a historical oddity and a sign of the times. The eccentric, sometimes graphomaniacal texts of the “writer and publicist”, as he described himself, were based on the innovative intellectual achievements of a 19th-century messianic thinker Józef Maria Hoene-Wroński, as a programme to address the realities of Poland in the 1930s – a country struggling with serious problems, such as authoritarianism, poverty, anti-Semitism and a hostile international environment. The political solution based on an intellectual endeavour (applying Hoene-Wroński’s “law of creation”) seemed unusually simple, so it is hardly surprising that Kwieciński’s lectures were very popular in the Polish provinces. In addition to elements of the biography of a little-known, original hero, the article contains conclusions relating to the realities of the Second Polish Republic towards the end of its existence.

Adaptive Incremental Modeling Combined with Hidden Markov Modeling in Cyber Security
Authors: Xu Liwen
Published: September 2024

This study examines the limitations of traditional CS technology, which relies heavily on labeled data and is unable to detect new types of attacks in real time. It proposes an optimization and improvement of CS technology through the use of hidden Markov models and adaptive incremental models. The research is conducted from three perspectives: the actual collection of security information, the extraction of unknown protocol features, and the development of detection models. Firstly, a unified method of collecting safety information is established, and a safety information database is obtained by combining information filtering, integration, and association analysis. Secondly, the modified hidden Markov model is used to parse the unknown protocol messages and extract the appropriate features. Finally, the extracted information features are applied to the adaptive incremental model for intrusion detection. The experimental results indicated that the average time cost of the data processing method is 25.841 ms, and the identification accuracy of the intrusion detection model for new attack types reaches 91.15%. The model designed by the research can adapt to the complex and changeable network environment and accurately detect network intrusion while ensuring operational efficiency, which provides a new research direction for the field of CS.
Theoretical study of a triple-band tunable terahertz metamaterial absorber with polarization insensitive and high refractive index sensing based on bulk Dirac semimetal
Authors: Zhou Weijun , Qin Xuefeng , Chen Yuxuan , Zhao Qian , Huang Yang , Zhou Haiquan , Xu Nianxi , Wang Ben-Xin
Published: September 2024

In this paper, a triple-band metamaterial absorber in the terahertz frequencies is proposed, and its refractive index sensing characteristics are analyzed, where the bulk Dirac semimetal (BDS) periodic array is on top of a photonic crystal slab backed with a metal ground plane. The simulation results show that the absorber achieves three perfect absorption peaks in the range of 3.4–5.2 THz, whose absorption rates are over 96%, and a maximum quality factor (Q) of 74.1. The designed absorber exhibits excellent polarization insensitivity and dynamic tunability; further, the tuning of the Fermi energy level of BDS enables the dynamic adjustment of absorption frequencies and absorption rates of these peaks. By analyzing the distributions of the electromagnetic field and different structural parameters, it is revealed that the absorber mainly dissipates the electromagnetic wave through coupled resonance and localized surface plasmon resonance (LSPR) effects to achieve perfect absorption. Further, the metamaterial absorber shows the capacity to detect analytes with varying refractive indices, and the absorber has a maximum sensitivity S of 405 GHz/RIU with high detection accuracy. This work provides novel design options for triple-band terahertz metamaterial absorbers and their potential applications in refractive index sensing.

Direct generation of a narrowband EUV vortex with ring Pearcey–Gaussian-vortex-beam-driven harmonics
Authors: Li Dan , Deng Fu , Hong Weiyi
Published: September 2024

The generation of tunable extreme-ultraviolet (EUV) vortex beams is highly sought after for optoelectronic applications in the EUV region. In this study, we investigate the generation of vortex high-order harmonics using a ring Pearcey–Gaussian vortex beam as the driving source. We analyze the beam’s spatial structure through phase-matching conditions and simulate high-order harmonic generation by solving the Maxwell wave equations. The beam’s self-focusing characteristics and low-diffraction properties after focusing significantly enhance harmonics near the 53rd order, indicating the generation of a narrowband EUV vortex. Our findings underscore the advantages of using a ring Pearcey–Gaussian vortex beam for narrowband EUV vortex generation, paving the way for creating tunable vortex high-order harmonics or attosecond pulses with innovative vortex beams.

Published: September 2024

We propose and numerically investigate a fractional-soliton mode-locked fiber laser by utilizing an intracavity spectral pulse shaper (SPS). The fiber laser can generate stable fractional-soliton pulses for three different Lévy index α (1 < α < 2), whose profiles are all close to the sech shape. We find that the positions of Kelly sidebands, pulse energy, and peak power of the emitted fractional pulses conform to three theoretical expressions, respectively. The numerical results are in good agreement with the theoretical analyses. In addition, the intracavity dynamics of the fractional pulses have been discussed. Our findings not only deepen the fundamental understanding of temporal fractional soliton but also provide a novel, to the best of our knowledge, approach to generating stable ultrashort fractional pulses.

Published: September 2024

Multifocal structured illumination microscopy (MSIM) is a popular super-resolution imaging technique known for its good probe compatibility, low laser power requirements, and improved imaging depth, making it widely applicable in biomedical research. However, the speed of MSIM imaging is typically constrained by the approaches employed to generate and scan the laser foci across the sample. In this study, we propose a flexible two-photon excitation MSIM method using a pair of acousto-optic deflectors. By adopting addressable scanning (AS) and synchronized capturing, MSIM super-resolution imaging can be performed in multiple discrete regions of interest (ROIs) within the field of view. Notably, this AS-MSIM scheme not only enhances the speed of MSIM imaging but also alleviates photobleaching and phototoxicity to biological samples. We demonstrate its potential by achieving super-resolution imaging of selected mitochondria within cells at a frame rate of 4 Hz. Furthermore, we deliberate the possibility of even faster imaging.

Published: September 2024

This study explores the properties of a laser beam shaping system comprising an acousto-optic dispersive delay line (AODDL) and an acousto-optic tunable filter (AOTF) for ultrashort laser pulse shaping. The system demonstrates the AODDL's ability to generate signals with arbitrarily positioned transmission windows and investigates the impact of spectral width on field distributions. The AOTF's frequency scanning and simultaneous control of two and three spectral components are presented. The experimental setup utilizes femtosecond laser radiation, and the results highlight the system's versatility for programmable spectral and spatial filtering, offering potential applications in advanced optical manipulation.

The dispersal of Homo sapiens across Eurasia during MIS 3 in the Late Pleistocene is marked by technological shifts and other behavioral changes, known in the archaeological record under the term of Initial Upper Paleolithic (IUP). Bacho Kiro Cave in north Bulgaria, re-excavated by us from 2015 to 2021, is one of the reference sites for this phenomenon. The newly excavated lithic assemblages dated by radiocarbon between 45,040 and 43,280 cal BP and attributed to Homo sapiens encompass more than two thousand lithic artifacts. The lithics, primarily from Layer N1-I, exist amid diverse fauna remains, human fossils, pierced animal teeth pendants, and sediment with high organic content. This article focuses on the technological aspects of the IUP lithics, covering raw material origin and use-life, blank production, on-site knapping activities, re-flaking of lithic implements, and the state of retouched lithic components. We apply petrography for the identification of silicites and other used stones. We employ chaîne opératoire and reduction sequence approaches to profile the lithics techno-typologically and explore the lithic economy, particularly blade production methods, knapping techniques, and artifact curation. Raw material analysis reveals Lower Cretaceous flints from Ludogorie and Upper Cretaceous flints from the Danube region, up to 190 km and 130 km, respectively, from Bacho Kiro Cave, indicating long-distance mobility and finished products transport. Imported lithic implements, were a result of unidirectional and bidirectional non-Levallois laminar technology, likely of volumetric concept. Systematic on-anvil techniques (bipolar knapping) and tool segmentation indicate re-flaking and reshaping of lithic implements, reflecting on-site curation and multifaceted lithic economy. A limited comparison with other IUP sites reveals certain shared features and also regional variations. Bacho Kiro Cave significantly contributes to understanding the technological and behavioral evolution of early Homo sapiens in western Eurasia.
Do local and landscape context affect the attractiveness of flower gardens to bees?
Authors: Eldridge Devon S. , Khalil Amani , Moulton John K. , Russo Laura
Published: September 2024

Planting floral resources is a common strategy for increasing the abundance and diversity of beneficial flower-visiting insects in human-modified systems. However, the context of the local area and surrounding landscape may affect the attractiveness of these floral resource provisioning plots. We compared the relative effects of local floral resources and surrounding urban land-use on the abundance of bees on flowering plants in common gardens in eastern Tennessee, USA. We planted four types of common garden plots at each of five different landscapes representing a variety of surrounding land use: 1) Urban Garden, 2) Forage Grassland, 3) Mixed Agriculture, 4) Forest, and 5) Organic Farm. Each common garden plot type had a fixed plant community representing one of three plant families (Asteraceae, Fabaceae, Lamiaceae) or a mix of all three, and all four common gardens were replicated at all the sites. We concurrently sampled bees in the garden plots and in a 50 m radius (local area) around the garden plots. We found that the size of the floral display (i.e. the visual display size of flowers) and diversity of flowers in the local area did not affect bee abundance or species richness in the garden plots. Although there was a significant positive association between developed land use in a 2 km radius and bee abundance in the gardens, the effect was small, and there was no relationship between land use and bee abundance or species richness in the local area. There were significant differences in the composition of the bee community between the local area and garden plots, but the largest determinants of bee community composition and species richness in the gardens were floral display size and variation in the garden plant species in bloom. This finding is promising for anyone wishing to promote pollinator populations by providing more floral resources.

The traditional crop calendar for yam (Dioscorea spp.) in South-Kivu, eastern Democratic Republic of Congo (DRC), is becoming increasingly inadequate given the significant climatic variability observed over the last three decades. This study aimed at: (i) assessing trends in weather data across time and space to ascertain climate change, and (ii) optimizing the yam crop calendar for various South-Kivu agro-ecological zones (AEZs) to adapt to the changing climate. The 1990–2022 weather data series were downloaded from the NASA-MERRA platform, bias correction was carried out using local weather stations’ records, and analyses were performed using RClimDex 1.9. Local knowledge and CROPWAT 8.0 were used to define planting dates for yam in different AEZs. Results showed the existence of four AEZs in the South-Kivu province, with contrasting altitudes, temperatures, and rainfall patterns. Climate change is real in all these South-Kivu’s AEZs, resulting either in rainfall deficits in some areas, or extreme rainfall events in others, with significant temperature increases across all AEZs. Suitable yam planting dates varied with AEZs, September 15th and 20th were recommended for the AEZ 2 while October 15th was optimal for AEZ 1, AEZ 3, and AEZ 4. However, none of the planting date scenarios could meet the yam water requirements in AEZ1, AEZ3, and AEZ4, since the effective rainfall (Pmm) was always inferior to the plant water demand (ETc), meaning that soil water conservation practices are needed for optimum plant growth and yield in these AEZs. This study does not recommend planting yam during the short rainy season owing to prolonged droughts coinciding with critical growth phases of yam, unless supplemental irrigation is envisaged. This study provided insights on the nature of climate change across the past three decades and suggested a yam crop calendar that suits the changing climate of eastern DRC.
Decolonizing animation

AI animation technologies, Carib epistemology and the western ex0tic: Rivers run between worlds
Authors: Starr Helen
Published: September 2024

This article explores how an artificially intelligent (AI) animation praxis, encompassing traditional Carib practices and AI technologies, serves as a bridge between Indigenous knowledge and contemporary experiences. It delves into AI animation’s ability to alter consciousness and perception utilizing virtual reality (VR), augmented reality (AR), and game engines (GE), drawing from scholarship such as Sri Lankan-born Dr Laleen Jayamanne’s decolonial avatar theory to reconsider the uncanny valley phenomenon. The sense of revulsion that a computer-generated figure can evoke in a viewer is often influenced by cultural and ethnic factors. What appears eerie or unsettling to one cultural group may be perceived as typical or dominant by another. By hijacking bodily processing, interactive animation apps create immersive narratives, challenging traditional philosophical debates and contrasting Carib and western world-views. Emphasizing the integration of diverse perspectives, the article highlights the potential for animation to reshape epistemologies arising from the decolonial Caribbean and Latin American ontological turn. As AI-driven animation evolves, it could lead to more holistic ways of understanding the world, transcending Eurocentric biases. The Indigenous nature-centric ontology of Carib people fosters an interconnectedness with the environment, viewing all elements – including stones, rivers, plants and animals – as imbued with informational significance. Abiogenesis, or the origin of life, is understood as the interplay of information and energy. All life emerges from non-living components, akin to a cosmic play where information serves as both script and energy driving the scenes. Landauer’s principle, which posits that creating things demands more energy than erasing them, serves as a rulebook for the universe, outlining the relationship between information and the energy required to set things in motion. This radical theory contrasts with historical binaries that compartmentalize the metaphysical and material worlds.

‘Being in the kindergarten of blended learning’
Authors: Wood Yvonne
Published: September 2024

The potential of blended learning has yet to be reached and this paper presents an alternative lens for researching teachers who work with blended learning environments. The teachers‘ role in creating blended learning environments is not yet well understood. This paper proposes the Social Construction of Technology (SCOT) as a model that may be used to explore the processes that teachers engage in when creating blended learning environments. Exploring the ways in which teachers are creators of blended learning environments provides a new lens for sustainable practice. This may signify a shift away from the focus of attempting to create a perfect product to an emphasis on sharing the process development. This paper first presents an overview of the SCOT model which is followed by examples of the ways in which the SCOT model was applied in a recent research project.
“An image hurts more than 1000 words?”
Authors: Oehmer-Pedrazzi Franziska , Pedrazzi Stefano
Published: September 2024

Visual content captures attention, is easy to understand, and is more likely to be remembered. However, it is not limited to conveying informative content; it can also be used to propagate hate. While existing research has predominantly focused on textual hate speech, this study aims to address a research gap by analyzing the characteristics of visual hate, including its channels, intensity, sources, and targets, through a standardized manual content analysis. The hate images were collected through the citizen science approach of data donation. Findings highlight that transgender individuals and migrants are the primary targets of visual hate. It reveals a presence of hate images not only on communication platforms but also in various intermediaries and journalistic media. Half of these images use factual or humorous methods to discriminate against individuals or groups, while an equal number adopt a highly aggressive tone. The study suggests governance measures to combat this issue effectively.
Optimizing ICSI outcomes in women with PCOS: the influence of BMI, hormonal levels, and male fertility parameters
Authors: Hassan Muhjah Falah , Abdul Kadim Hind , Al-Yasiry Rabab Zahir , Hafedh Sagban Sahbaa , Dutta Sulagna , Sengupta Pallav
Published: September 2024

Objectives

Women with PCOS often experience significant difficulties in achieving spontaneous pregnancy. Intracytoplasmic sperm injection (ICSI) is a viable treatment option for these patients, offering an acceptable success rate. This study purposes to identify factors that may positively or negatively influence pregnancy rates in PCOS women undergoing ICSI and explore potential modifications to enhance successful pregnancy outcomes.

Methods

The study included ninety sub-fertile couples with female partners with diagnosed PCOS. Comprehensive evaluations of the partners included medical history, physical examination, hormonal analysis, transvaginal ultrasound (TVUS), and seminal fluid analysis. All couples underwent ICSI. Pregnancy rates were determined by positive pregnancy tests 14 days after fresh embryo transfer, and participants were divided into two groups: pregnant and non-pregnant.

Results

Of the 90 women who underwent ICSI cycles, 24 achieved pregnancies, resulting in a pregnancy rate of 26.66 %. Non-pregnant women had significantly higher body mass indices (BMI). Additionally, women with elevated cycle day 2 serum estradiol (E2) levels and low follicle-stimulating hormone (FSH) levels exhibited significantly lower pregnancy rates. Women whose male partners had abnormal semen parameters also demonstrated significantly lower pregnancy rates.

Conclusions

Several factors negatively impact pregnancy rates in PCOS women undergoing ICSI, including high BMI, elevated E2, low FSH levels on cycle day 2, a lower number of mature oocytes, and male factor sub-fertility. Many of these factors can be mitigated through the use of ICSI, thereby improving the chances of achieving a successful pregnancy.

The fistulous tract exemplifies a chronic wound that presents itself as a subcutaneous tunnel exiting through the skin with presence of contaminated secretion. When the tract is infected with multi-resistant bacteria and there is biofilm presence, the medical treatment is, therefore, a lot more complicated, prolonged in time and expensive due to the cost of diagnostic procedures, veterinary management, medicines, and hospital boarding, which is often required. In addition, normally, the expected zootechnical use of the animal cannot be carried out until it heals, and its price is devalued due to the injury. The role of bacterial biofilms in chronic infected wounds is addressed and due to the difficulty in identifying them, it is advisable to look for specific clinical signs suggestive of the problem and apply the “Percival´s Diagnostic Algorithm” for the detection of biofilm. Treatment should be based on repeated debridement and the application of topical antimicrobial therapy without prescribing systemic antibiotics unless there are signs of generalized infection. A treatment protocol to improve the management of the injury and the use of alternative antiseptic substances to current conventional antibiotics are discussed, as well as the application of “ONE HEALTH” concepts to deal with such problem.
Pricing Mechanism in Panyabungan Tradisional Market Viewed from Islamic Economic Perspective
Authors: Lubis Rini Hayati
Published: September 2024

This study analyzes the pricing mechanism in the Panyabungan traditional market using the perspective of Islamic economics. The Panyabungan tradisional market is the focus of research because it is the local economic center of the Muslim community. Using a qualitative approach, data is collected through observation and interviews with traders and sellers as well as market stakeholders. The results of the study show that the pricing mechanism in the Panyabungan Old Market is largely based on market forces, which is not in accordance with Islamic economic principles that emphasize fairness in prices. In the traditional market of Panyabungan, there is still intransparency related to prices, price increases at certain moments that are not affected by the substance of the availability of goods, and buying and selling credit without paying attention to sharia principles. The implications of this study reinforce the importance of understanding and applying Islamic economic principles in traditional market practices to achieve the goals of economic justice and sustainability at the local level.

This study aims to analyze the efficient market form of the Jakarta Islamic Index. The methodology used is an event study with a window period of 20 days, including ten days before and ten days after the announcement of composition changes held twice a year. The sample consists of 102, with 30 companies listed during the study period and 36 companies excluded and re-listed following the composition change announcements. The analysis technique used is the Paired Sample T-test. The findings reveal no differences in abnormal returns and trading volume activity before and after the announcement. This suggests that the market had already absorbed the announcement information before the event, resulting in a weak reaction and indicating that the announcement did not significantly impact the Jakarta Islamic Index. This implies that the index operates in a semi-strong form of market efficiency. Consequently, companies listed in the index may need additional strategies to improve their stock performance. To provide further insight, this study also examines the average stock trading activity of companies that enter and exit the composition of the Jakarta Islamic Index for the 2019-2023 periods.

The Russian-Ukrainian conflict resulted in the transformation of modern logistics networks and supply chains to adapt to the challenges faced. This fact is particularly noticeable in the agricultural sector. Bottlenecks in the flow of raw materials have caused a global food crisis. Therefore, solutions are constantly being sought to minimize the negative effects of war, including: through the organization of solidarity corridors, as well as causing reductions in food prices. The research problem was formulated as a question: How do projects undertaken by the EU to eliminate the negative effects of war in the food supply chain sector affect their security? Additionally, a study was carried out to determine whether the actions undertaken were consistent with the adopted “farm to fork” strategy. The analysis carried out made it possible to identify the effects of the Russian invasion of Ukraine from the perspective of the global food market, along with presenting and assessing the actions taken as a result of the crisis in global food supply chains. The research conducted showed that as a result of disruptions in the functioning of global supply chains, food prices increased by approximately 34% in the first period of the conflict (March 2022). Currently, after introducing, among others, solidarity corridors, their growth is recorded at the level of 6.4%, by increasing the security of the flow of goods.
Teoria kalifatu Al-Mawardiego i jej związek ze współczesnym islamizmem
Authors:   Uniwersytet Jana Długosza w Częstochowie, Zasuń Anna
Published: September 2024

The article presents the concept of the caliphate of theologian and jurist at the turn of the 10th and 11th centuries, Al-Mawardi, based on his work Al-Ahkam as-sultaniyya and the socio-political nature of the period of the Abbasid dynasty, which was the context of its creation. Based on a detailed analysis of Al-Mawardi’s views on political power in Islam (traditional caliphate), the author’s aim was to show the connection of this theory with selected elements of the contemporary ideology of Islamism, and thus attempt to answer the question about the continuity of Muslim political thought. Considering the changes of the caliphate in times of Al-Mawardi, but also in later periods, including the ones that occurred in the Islamic world after the fall of the Ottoman Empire, the author argues that views on power in Islam were conditioned by a complex socio-political context, which was influenced by factors internal and external to the world of Islam. Discussed theory of Al-Mawardi’s caliphate constitutes the basis for the search for analogies in the political doctrine of contemporary Islamic reformers and the ideology of Islamism, which in turn allows Al-Mawardi’s views to be considered appropriate also for the contemporary concept of power in Islam.

Key Points

Peritubular endothelial cells have a hypoglycolytic metabolism in CKD.

Restoration of glycolysis in CKD peritubular endothelial cells by overexpressing 6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase attenuates microvascular rarefaction and kidney fibrosis.

Strategies targeting the metabolic defect in glycolysis in peritubular endothelial cells may be effective in the treatment of CKD.

Background

Peritubular endothelial cell dropout leading to microvascular rarefaction is a common manifestation of CKD. The role of metabolism reprogramming in peritubular endothelial cell loss in CKD is undetermined.

Methods

Single-cell sequencing and metabolic analysis were used to characterize the metabolic profile of peritubular endothelial cells from patients with CKD and from CKD mouse models. In vivo and in vitro models demonstrated metabolic reprogramming in peritubular endothelial cells in conditions of CKD and its contribution to microvascular rarefaction.

Results

In this study, we identified glycolysis as a top dysregulated metabolic pathway in peritubular endothelial cells from patients with CKD. Specifically, CKD peritubular endothelial cells were hypoglycolytic while displaying an antiangiogenic response with decreased proliferation and increased apoptosis. The hypoglycolytic phenotype of peritubular endothelial cells was recapitulated in CKD mouse models and in peritubular endothelial cells stimulated by hydrogen peroxide. Mechanically, oxidative stress, through activating a redox sensor kruppel-like transcription factor 9, downregulated the glycolytic activator 6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase expression, thereby reprogramming peritubular endothelial cells toward a hypoglycolytic phenotype. 6-phosphofructo-2-kinase/fructose-2, 6-bisphosphatase overexpression in peritubular endothelial cells restored hydrogen peroxide–induced reduction in glycolysis and cellular ATP levels and enhanced the G1/S cell cycle transition, enabling peritubular endothelial cells to improve proliferation and reduce apoptosis. Consistently, restoration of peritubular endothelial cell glycolysis in CKD mice, by overexpressing endothelial Pfkfb3, reversed the antiangiogenic response in peritubular endothelial cells and protected the kidney from microvascular rarefaction and fibrosis. By contrast, suppression of glycolysis by endothelial Pfkfb3 deletion exacerbated microvascular rarefaction and fibrosis in CKD mice.

Conclusions

Our study revealed a disrupted regulation of glycolysis in peritubular endothelial cells as an initiator of microvascular rarefaction in CKD. Restoration of peritubular endothelial cell glycolysis in CKD kidney improved microvascular rarefaction and ameliorated fibrotic lesions.
