Guiné-Bissau
Authors: Monteiro Ivanilson Dinis Geraldo
Published: November 2024

A Guiné-Bissau é uma nação situada na Costa Ocidental da África com uma superfície de 36.125 km². O país despõe de 2 milhões de hectares de floresta, constituindo assim um potencial ecológico rico e diversificado, o que permite acolhimento de vida das mais variadas espécies. Apesar dessa riqueza ecológico, digno de proteção e preservação, mas o que vem sendo observado, ultimamente na Guiné-Bissau, é a sua delapidação desenfreada pela atividade humana, com interesses econômicos obscuros. Atividade essa com grande potencialidade de afetar negativamente a vida da geração vindoura, além dos efeitos negativos que a população já está vivenciando, enfrentando. Nesse sentido, baseando no exposto e reportando o texto do Pedro Felipe Narciso intitulado “O golpe de estado, a burocracia e a teoria marxista do Estado”, o ensaio objetiva-se refletir sobre as cíclicas instabilidades política e/ou burocrática associadas a devastação florestal na Guiné-Bissau.
Ensaio crítico sobre a corrupção na produção científica brasileira
Authors: Marques Ana Alice
Published: November 2024

Corrupção é fenômeno de interesse internacional, que vem ganhando espaço na agenda pública e também na produção acadêmica. No intuito de captar como a corrupção vem sendo debatida na produção científica brasileira, foi feita uma revisão assistemática, contemplando também como o assunto é debatido no campo da Saúde. Foi intuito também tecer crítica marxista a concepção mais comum de corrupção. As revisões de literatura demonstraram que houve aumento da produção a partir da década de 2010, sendo maioria no campo do Direito. Os estudos são majoritariamente de âmbito público, sem especificar poder ou esfera de governo e tem maior uso de referências estrangeiras. Há necessidade de ampliação nos estudos, inclusive com leituras críticas ao discurso dominante, como foi o caso do questionamento feito sobre a separação entre “público” e ”privado”, ”político” e ”econômico” da definição de corrupção. Destacou-se uma visão marxista de corrupção enquanto ideologia do Estado Capitalista.
Revisitando a teoria da derivação e sua crítica aos limites do Estado social
Authors: Pessoa Robertonio Santos
Published: November 2024

O artigo revisita a teoria da derivação do Estado, uma corrente marxista surgida na Alemanha nos anos 1970 e que trouxe grande contribuição para uma crítica marxista do Estado social. Essa teoria critica a visão tradicional do Estado como instância pública, impessoal, apartada da dinâmica e dos embates da vida social e voltada para o atendimento dos interesses gerais da sociedade. Disso resulta que o equacionamento dos conflitos e das contradições da sociedade capitalista deve ocorrer, segundo o pensamento político-jurídico liberal, por meio de uma instância política separada da sociedade, em que a mediação dos interesses conflitantes ocorrerá por meio da adoção de medidas de interesse público. A teoria da derivação revela os problemas e contradições dessa concepção. Para essa teoria, o Estado se apresenta como uma relação social contraditória fundamental, que somente pode ser explicada sob a luz das contradições básicas da sociabilidade capitalista. Os contornos do Estado e da sua atividade devem ser examinados no contexto da sociedade capitalista como um todo, como resultante de um devir histórico e de estruturas sociais dinâmicas e contraditórias. Os aportes da teoria da derivação podem trazer novas luzes para um exame do atual contexto latino-americano e brasileiro, marcado pela volta da esquerda ao poder, na medida em que apresentam uma reflexão crítica sobre os limites das intervenções do Estado no campo social e econômico quando voltadas para a concretização de projetos emancipatórios e para a construção de sociedades mais justas e igualitárias.
“Festa da Selma”
Authors: Grischke Lucas Lopes
Published: November 2024

Tendo em vista a violenta invasão de prédios públicos datada de 8 de janeiro de 2023, combinada em rede social por manifestantes antidemocráticos que promoveram depredações e violações do patrimônio nacional, tais como as ocorridas na sede do Supremo Tribunal Federal (STF), este trabalho se debruça sobre os conceitos de neofascismo e de fake news, de modo a analisar sua compatibilidade teórica com as práticas ocorridas em Brasília. Para tanto, sob a perspectiva conceitual será utilizada análise bibliográfica com duas categorias principais: fascismo e fake news. Serão explanados conceitualmente o fascismo e suas derivações atuais, incluídas reflexões sobre a instrumentalização do ódio por meio das fake news e o abalo na ordem democrática causado pelas manifestações criminosas na capital federal. Entende-se que o refreamento da disseminação de fake news pode ser um importante passo inicial no combate aos extremismos propostos por ideologias de caráter fascista que tenham por intenção abolir o Estado democrático de direito.

Islamische Theologie der Religionen. Eine Einführung und Bewertung
Authors: Mirsadri Saida
Published: November 2024

This article analyses the development of Islamic theology of religions in recent decades and classifies the various approaches into two main categories: exclusivism and pluralism. Furthermore, it argues that, in contrast to the historical Islamic tradition, which predominantly pursued a rather exclusivist approach, a theology of religions based exclusively on the Qurʾan offers significantly greater potential for an Islamic theology of pluralism.
Activism and the academy: implementing and evaluating activist-in-residence programmes
Authors: Stevens Ed , Dhavan Nayana , Matzner Sebastian
Published: November 2024

Activist-in-residence programmes in universities represent a paradox: what space exists for activists in institutions which are often seen as re/creating and perpetuating hegemonic structures, and/or as the epistemic sources and reinforcers of the very ideas which activists aim to disrupt? In this article, we examine the motivations and theoretical considerations that drive the establishment of such programmes, and discuss the tensions and possibilities that arise from this inherent paradox. Based on an analysis of existing activist-in-residence programmes and current theoretical framings, we propose a reflexive process evaluation framework for their development and evaluation. We then deploy the framework to critically review a recent activist-in-residence programme hosted by Queer@King’s, an interdisciplinary research centre specialising in gender and sexuality at King’s College London, UK.
The fractional Hopf differential and a weak formulation of stationarity for the half Dirichlet energy
Authors: Gaia Filippo
Published: November 2024

We obtain a weak formulation of the stationarity condition for the half Dirichlet energy, which can be expressed in terms of a fractional quantity, related to the trace of the Hopf differential of the harmonic extension of the original map. As an application we show that conformal harmonic maps from the disc are precisely the harmonic extensions of stationary points of the half Dirichlet energy on the circle. We also derive a Noether theorem and a Pohozaev identity for stationary points of the half Dirichlet energy.
Struwe’s global compactness and energy approximation of the critical Sobolev embedding in the Heisenberg group
Authors: Palatucci Giampiero , Piccinini Mirco , Temperini Letizia
Published: November 2024

We investigate some of the effects of the lack of compactness in the critical Folland–Stein–Sobolev embedding in very general (possible non-smooth) domains,
by proving via De Giorgi’s Γ-convergence techniques that optimal functions for a natural subcritical approximations of the Sobolev quotient concentrate energy at one point. In the second part of the paper, we try to restore the compactness by extending the celebrated Global Compactness result to the Heisenberg group via a completely different approach with respect to the original one by Struwe [M. Struwe,
A global compactness result for elliptic boundary value problems involving limiting nonlinearities,
Math. Z. 187 1984, 4, 511–517].
Electroacupuncture on GB acupoints improves osteoporosis via the estradiol–PI3K–Akt signaling pathway
Authors: Wang Xinyu , Zeng Xiyu , Long Yu , Du Yanfei , Li Chang , Jiang Hua , Li Guang
Published: November 2024

Recent studies have reported that electroacupuncture (EA) can treat osteoporosis, but most of which were based on the “kidney governing bones” theory. However, the ancient Chinese medical textbook Huangdi Neijing pointed out that “Gallbladder Meridian of Foot Shaoyang” correlates with bone diseases, including osteoporosis, although the therapeutic regimens were lost after the Tang Dynasty. Here, we explored whether EA at GB points improves osteoporosis and its underlying mechanism. We constructed ovariectomized mice and treated them with EA at GB30 (Huantiao), GB34 (Yanglingquan), and GB39 (Xuanzhong) acupoints. EA treatment significantly improved bone parameters in osteoporotic mice, as evidenced by micro-computed tomography and histological assessment. Additionally, EA treatment elevated the serum levels of estradiol and SOD that were downregulated in osteoporotic mice. Transcriptome and qPCR results verified that EA treatment upregulated the expression of genes associated with bone formation. Moreover, transcriptome analysis revealed differential enrichment of the PI3K–Akt pathway. Furthermore, Western blot analysis demonstrated that estradiol partially counteracted a reduction in p-AKT expression induced by hydrogen peroxide. These findings indicate that EA treatment increases serum estradiol levels in mice, thus inhibiting osteoporosis induced by oxidative stress. This effect is achieved by activating the PI3K–Akt signaling pathway.
Transcriptomic analysis of liver immune response in Chinese spiny frog (Quasipaa spinosa) infected with Proteus mirabilis

Published: November 2024

The expansion of Chinese spiny frog (Quasipaa spinosa) aquaculture has increased the prevalence and severity of diseases such as “skin rot” disease, which is triggered by harmful bacteria. Previous studies have mainly focused on pathogen identification and vaccine development. However, frog immune responses following pathogenic bacterial infection have hardly been investigated. We thus examined the immune response of Chinese spiny frog to skin rot disease caused by Proteus mirabilis. The liver transcriptomes of Chinese spiny frog infected with P. mirabilis were sequenced using the MGISEQ-2000 platform. We identified a total of 138,936 unigenes, of which 32.35% were known genes. After infection with P. mirabilis, 801 genes showed differential expression, with 507 upregulated and 294 downregulated genes. These differentially expressed genes were enriched in pathways related to cytokine–cytokine receptor interaction, TNF signaling, and toll-like receptor signaling, according to Kyoto Encyclopedia of Genes and Genomes analysis. Following P. mirabilis infection, immune genes, including H2-Aa, hamp1, LYZ, CXCL10, and IRAK3, were significantly upregulated, while NLRP3, ADAM19, TYK2, FETUB, and MSR1 were significantly downregulated. The results provide important information on how the immune system of Chinese spiny frog responds to P. mirabilis infection and help understand the development of skin rot in cultured frog species.
Periprosthetic joint infections – a scoping review
Authors: Youssef Yasmin , Hättich Annika , Klepka Kim Lydia
Published: November 2024

Periprosthetic joint infections (PJIs) are dramatic complications after primary total joint arthroplasty. Despite increasing research in this field, the diagnosis, classification, and management of PJI remain a challenge. This is mainly due to the heterogenous clinical presentation of PJI in clinical routine and patient-related factors as secondary diagnosis and periprosthetic tissue condition. The early detection of PJI is essential for adequate treatment. However, there is no definition for PJI with 100 % sensitivity or a negative predictive value. This can potentially lead to a delayed or missed diagnosis of PJI. Furthermore, the surgical and antibiotic treatment is among the most discussed topics in PJI literature. There is no international consensus on the treatment of different PJI entities. Concludingly many aspects of PJI diagnostics and treatment remain controversially discussed and current studies are only comparable to a limited extent due to study heterogeneity and limited comparability.
Toeplitz operators associated with the Whittaker Gabor transform and applications
Authors: Mejjaoli Hatem
Published: November 2024

The Whittaker Gabor transform (WGT) is a novel addition to the class of Gabor transforms, which has gained a respectable status in the realm of time-frequency signal analysis within a short span of time. Knowing the fact that the study of the time-frequency analysis is both theoretically interesting and practically useful, the aim of this article is to explore two more aspects of the time-frequency analysis associated with the WGT including the spectral analysis associated with the concentration operators and the scalogram.
The construction of anti-pandemic image: a semiotic study of the role metaphors play in pandemic discourse in China
Authors: Li Ke , Wang Yanyu , Li Shukang
Published: November 2024

The pandemic has attracted extensive media attention around the world. In reports on the pandemic, metaphors are widely used to frame pandemic events through cross-domain mappings. Based on critical metaphor analysis, this study examines the metaphors in pandemic reports published in China Daily, the largest government-owned English-language newspaper in China and explores the metaphorical construction of China’s anti-pandemic image. We find more than 13 metaphor varieties, among which, the metaphors of war, journey, and family and friend are dominant. Through these metaphors, China is largely constructed as a people-oriented, united, resilient, responsible, and friendly country as well as a victim of political stigmatization. We argue that the stance and ideology of China Daily and the international background of infodemic influence the representation of China’s anti-pandemic image.
Motivational dysregulation with melanocortin 4 receptor haploinsufficiency
Authors: Steiner Alex M. , Roscoe Robert F. , Booze Rosemarie M. , Mactutus Charles F.
Published: November 2024

Obesity, by any standard, is a global health crisis. Both genetic and dietary contributions to the development and maintenance of obesity were integral factors of our experimental design. As mutations of the melanocortin 4 receptors (MC4R) are the leading monogenetic cause of obesity, MC4R haploinsufficient rats were fed a range of dietary fat (0–12 %) in a longitudinal design. Physiological and motivational assessments were performed using a locomotor task, a 5-choice sucrose preference task, an operant task with fixed and progressive ratios, as well as a distraction operant task. Dendritic spine morphology of medium spiny neurons (MSNs) of the nucleus accumbens (NAc), cells with ample D1 and D2 receptors, was also assessed. The percentage of lipid deposits in the liver of each rat was also analyzed using the Area Fraction Fractionator probe for stereological measurements. MC4R haploinsufficiency resulted in a phenotypic resemblance for adult-onset obesity that was exacerbated by the consumption of a high-fat diet. Results from the operant tasks indicate that motivational deficits due to MC4R haploinsufficiency were apparent prior to the onset of obesity and exacerbated by dietary fat consumption after obesity was well established. Moreover, MSN morphology shifted to longer spines with smaller head diameters for the MC4R+/− animals under the high-fat diet, suggesting a potential mechanism for the dysregulation of motivation to work for food. Increasing our knowledge of the neural circuitry/mechanisms responsible for the rewarding properties of food has significant implications for understanding energy balance and the development of obesity.

Published: November 2024

Objectives

Dysfunction of cerebral microcirculation due to SARS-CoV-2 infection has been postulated to be a plausible mechanism for the neurological symptoms of post-COVID-19 conditions (neuro-PCC), affecting oxygen homeostasis in the brain. In this study, we aimed to investigate the balance between cerebral oxygen delivery and consumption, measured by oxygen extraction fraction (OEF), in patients with neuro-PCC.

Methods

25 participants with neuro-PCC (8 previously hospitalized and 17 not hospitalized) and 59 age-matched healthy controls were studied. Global OEF was quantified using TRUST MRI and compared across the three groups. Associations between OEF and neurobehavioral measures were also evaluated in participants with neuro-PCC.

Results

OEF was significantly different (one-way ANCOVA-p=0.046) among the three groups, after accounting for age and sex. On post-hoc analyses, previously hospitalized neuro-PCC participants had significantly higher OEF (42.40 ± 5.40 %) than both uninfected controls (37.70 ± 5.09 %, p=0.032) and neuro-PCC participants without hospitalization (37.02 ± 5.05 %, p=0.015). Within the participants with neuro-PCC, OEF was significantly associated with locomotor function assessed with the 4-m walk gait speed score (β=−0.03, r=0.34, p=0.003).

Conclusions

Participants with neuro-PCC had altered cerebral OEF, which is also associated with slower locomotion. OEF is a promising marker for studying neuro-PCC.
Mexican queer influencers: corporeal-emotional social reconfigurations
Authors: Amao Ceniceros Melina
Published: November 2024

Purpose

The proliferation of queer influencers is framed in various phenomena that connect celebrity culture, digital psychopolitics and historical LGBTIQ+ movements, resulting in what we can call a post-reality. This study analyzes the tensions of bodies/emotions that arise from the visibility of queer influencers in Mexico in terms of representation and subjectivation of the sex/gender system, comparing visual narratives and political positionings or the lack of these in a necropolitical context for the LGBTIQ+ community.

Design/methodology/approach

A descriptive approach was carried out to have a overview of the diversity of profiles, and subsequently the mediabiography methodology was applied to a case study, with the selection of texts and digital images on an analytical model of three axes: corporality, emotionality and visuality.

Findings

The presence of Mexican queer influencers reconfigures dominant gender narratives and opens possible scenarios to recognize non-hegemonic corporalities and corporal practices. The content they generate articulates counter-narratives, counter-visualities and counter-emotionalities, such as pride in the face of shame, and anger in the face of the neoliberal depoliticization of pride.

Practical implications

Queer Studies guide the enactment of public policies that recognize the rights of sex/gender diversity. Mediabiography opens creative avenues for the study of contemporary visual narratives on social media.

Social implications

Counter-narratives, counter-visualities and counter-emotionalities legitimize the dignified existence of corporalities systematically and historically marginalized by the dominant gender model, and de-hierarchize life.

Originality/value

This is the first study that uses mediabiography for the analysis of visual narratives on social media. It contributes to new discussions for Communication Studies, Queer Studies and the Sociology of Bodies and Emotions.

Published: November 2024

The random motion (the diffusion) of guest molecules in nanoporous host materials is key to their manifold technological applications and, simultaneously, a ubiquitous phenomenon in nature quite in general. Based on a specification of the different conditions under which molecular diffusion in nanoporous materials may occur and of the thus resulting relevant parameters, a survey of the various ways of the measurement of the determining parameters is given. Starting with a condensed introduction to the respective measuring principles, the survey notably includes a summary of the various parameters accessible by each individual technique, jointly with an overview of their strengths and weaknesses as well as of the respective ranges of observation. The presentation is complemented by basic relations of diffusion theory and molecular modeling in nanoporous materials, illustrating their significance for enhancing the informative value of each measuring technique and the added value attainable by their combination. By providing guidelines for the measurement and reporting of diffusion properties of chemical compounds in nanopores, the document aims to contribute to the clarification and standardization of the presentation, nomenclature, and methodology associated with the documentation of diffusion phenomena in nanoporous materials serving for catalytic, mass separation, and other relevant purposes.
Planetarische Müllabfuhr – Gamechanger der Klimapolitik?
Authors: Edenhofer Ottmar , Kalkuhl Matthias
Published: November 2024

Dieser Beitrag spiegelt die in englischer Sprache gehaltene Thünen-Vorlesung von Ottmar Edenhofer auf der Jahrestagung des Vereins für Socialpolitik am 16. September 2024 in Berlin unter dem Titel „The (Missing) Third Pillar“ wider. Der Klimaökonom zeigt auf der Basis der gemeinsamen Forschung mit Matthias Kalkuhl, dass die internationale Klimapolitik vor einem Paradigmenwechsel steht: Durch CO2-Entnahmen („carbon dioxide removal“, CDR) sollen zusätzliche natürliche und technische Kohlenstoffsenken bereitgestellt werden, weil andernfalls die ambitionierten Klimaziele des Pariser Klimaabkommens nicht zu erreichen sind. CDR hat darüber hinaus die Funktion, die globale Kooperation zu erleichtern. Die Autoren entwickeln einen Vorschlag, wie eine Europäische Kohlenstoffzentralbank – die European Carbon Central Bank (ECCB) – eine Schlüsselrolle für Europas Beitrag zu einer planetarischen Müllabfuhr einnehmen kann. Den ökonomischen Anreiz liefern Clean-Up-Zertifikate, die die CO2-Entnahmen im EU-Emissionshandel finanzieren sollen.
Experimenting the compressive performance of low-carbon alkali-activated materials using advanced modeling techniques
Authors: Yang Xue , Wu Tong , Amin Muhammad Nasir , AlAteah Ali H. , Qadir Muhammad Tahir , Khan Suleman Ayub , Javed Muhammad Faisal
Published: November 2024

Activated alkali materials (AAMs) are progressively utilized as an alternative to Portland cement concrete owing to their widespread application and reduced environmental impact. This research employed multi-expression programming (MEP) and gene expression programming (GEP) to create predictive models for the compressive strength (CS) of AAMs based on a dataset of 381 entries with eight distinct variables. To further assess the significance of the factors influencing the CS of AAMs, sensitivity analysis was employed. In comparison to GEP, MEP was better at predicting AAM’s CS. The R
2 score of the GEP model was 0.953, which is lower than the MEP model’s 0.970 level. This was further backed up by the results of the statistical study and Taylor’s diagram. The results of the sensitivity analysis showed that specific surface area, aggregate volumetric ratio, and silicate modulus were the three most important parameters influencing the models’ outcomes. In comparison to models built in Python, the produced models yield novel empirical equations for AAM strength characteristic prediction. Researchers and professionals in the field could use these equations to find the best proportions for mix designs, cutting down on the need for repeated laboratory tests.
Zwischen Vulnerabilität und Resilienz: Der »Verstockungsauftrag« in der Theologie des Jesajabuches
Authors: Klein Anja
Published: November 2024

Ausgehend von einer Analyse des sogenannten »Verstockungsauftrags« in Jes 6,9–10 untersucht der Beitrag Konzeptionen von Vulnerabilität im Buch. Während im Ersten Jesaja die Vorstellung der situativen Verwundung dominiert, gehen die Texte im Bereich des Zweiten Jesaja von einer ontologischen Verwundung aus. Die zwei Vorstellungen gehen auf unterschiedliche Krisenerfahrungen zurück, die die theologiegeschichtliche Überlieferung ausbilden und sich für die Rezipientenkreise als resilienzfördernd erwiesen haben.
Maintenance-(Art)Work und die Arbeit am eigenen Bild
Authors: Kuhn Eva
Published: November 2024

This paper confronts two traditions that seem to complement each other: the sociohistorical tradition of women as reproductive and care workers lacking public visibility, and the art-historical tradition of women as images, as silent and fixed show objects. This combination of women’s work made invisible and their objectifying hyperexposure, which in turn relies on the invisibilization of the media and ideological dispositive, is addressed in a 1975 film by Chantal Akerman, Jeanne Dielman, 23, quai du Commerce, 1080 Bruxelles, in a particularly eloquent way. The paper places this film, a time-based portrait of a woman and her work, at the center of the investigation and takes it as a model of showing how the systemic determination of maintenance work – to maintain the status quo – can be overcome by making this work visible. By demanding our physical presence and endurance in facing and caring about another, this film enables us to perceive the details that make the difference and shows how maintenance (art)work can bring about change. It pointedly emphasizes the notion of the contemporary and allows us to ask the question of what is contemporary art once again.
De-linking Women and Nature: Care Work as a Subject of Art at the 1978 Venice Biennale
Authors: Bremer Maria
Published: November 2024

This essay revisits the 1978 Venice Biennale, titled From Nature to Art, from Art to Nature, to discuss the “gender neutral” use of both notions within the exhibition’s official discourse at the time. Against the backdrop of the 1970s, amid the momentum of second-wave feminism, initiatives concomitant to the exhibition discerned and challenged the persisting, though implicit, gendered implications of both art and nature, complicating the Biennale’s main narrative. These initiatives included self-organized shows by feminist collectives, namely the Gruppo Femminista Immagine from Varese and Donne/Immagine/Creatività from Naples. Informed by a Marxist perspective, both exhibitions, I argue, engaged with reproductive labor in original ways to contest and dismantle traditional assumptions of an inherent connection between women and nature.
Blurred Lines: Negotiating the In/Visibility of Maintenance in Feminist Art
Authors: Fiocco Fabiola
Published: November 2024

Visibility has been a key battleground for social movements such as feminism since the 1970s. In a socioeconomic landscape where the value and purpose of visibility vary according to gender, class, and race, it becomes even more urgent to critically investigate the mechanisms that organise it. By drawing from feminist and postcolonial theories, the article examines the negotiation of visibility in the artworks of Daniela Ortiz, Mayo Pimentel, and Liryc Dela Cruz. Through their work, these artists provide valuable insights into the aesthetic and political implications of in/visibility, particularly in relation to maintenance work, identified as a domain where these contradictions are most pronounced.

Current models for the study of neuroendocrine tumours (NETs) are severely limited. While in vitro (e.g. cell lines), ex vivo (e.g. organoids) and in vivo (e.g. mice) models all exist, each has limitations. To address these limitations and collectively identify strategies to move the NET models field forward, we held an inaugural NET models meeting, hosted by our founding group: Dr Lines (Oxford), Prof. Quelle (Iowa), Dr Dayton (Barcelona), Dr Ear (Iowa), Dr Marinoni (Bern) and Dr Guenter (Alabama). This two-day meeting in Oxford (UK) was organised and supported by Bioscientifica Ltd and was solely dedicated to the discussion of NET models. The meeting was attended by ∼30 international researchers (from the UK, EU, Israel, USA and Canada). Plenary talks were given by Prof. Thakker, who summarised NET research over the past few decades, and Dr Schrader, who described the process and pitfalls of generating new cell lines. Eight researchers also presented their work on topics ranging from human cell 3D bioprinting to zebrafish models and included novel ideas and improvements on current concepts. This was followed by an interactive workshop, where discussion topics included a summary of currently available NET models, limitations of these models, barriers to developing new models, and how we can address these issues going forward. This white paper summarises the key points raised in these discussions and the future aspirations of the NET Models Consortium. The next meeting will take place in Oxford (UK) in 2025; contact contact@netcancerfoundation.com for more information.
Hemin restores ACTH-induced glucocorticoid response in insulin-resistant rats

Published: November 2024

The sustained consumption of sucrose-rich diet has deleterious effects on the adrenal cortex, impairing its steroidogenic capacity. As hemin treatment has been shown to exert cytoprotective effects (e.g., by heme oxygenase 1 induction), our main goal was to analyze the adrenocortical function in rats treated with diet and hemin. Male Wistar rats fed standard chow and 30% sucrose in the drinking water (SRD) for 12 weeks ad libitum were injected with hemin for the last 2 weeks of treatment. mRNA and proteins were analyzed by real-time polymerase chain reaction, western blot or immunofluorescence, and corticosterone levels were assessed by radioimmunoassay. A decrease in lipid peroxides and an increase in the activity of catalase were detected in the SRD + H group. Moreover, pro-inflammatory markers (TNF-α, IL1β, CXCL10, NOS2, NALP3 and MCP1), IBA1+/ED1+ cells and NFκβ activation were still elevated in tissues from SRD + H-treated rats, whereas an increase in markers of macrophages with the M2-phenotype (ARG1, MRC1 and TGFβ) was also shown. Activation of ER stress in SRD-treated rats (CHOP, XBP1s and P58IPK) and the induction of apoptosis (TUNEL and the BAX/BCL2 mRNA ratio) were also attenuated by hemin. Finally, ACTH-stimulated glucocorticoid production, significantly decreased in SRD-treated rats, was upregulated by hemin. The consumption of SRD involves exposure of tissues to a higher metabolic load that could generate oxidative stress and a pro-inflammatory state. Deleterious consequences of these processes could account for the significant decrease in the ACTH-induced corticosterone output from the gland. By correcting these effects, hemin treatment was able to restore the hormone-induced adrenocortical response.
Withdrawal of a participant from a limited liability company: a review of case law
Authors: Vasylyeva V.V.
Published: November 2024

The article analyzes the procedure for withdrawal of a participant from the company and outlines the novelties of legislative regulation. It is determined that the withdrawal of a participant from the company can be realized both at the discretion of this person and with certain restrictions on the free withdrawal of a person from the company. The Law of Ukraine «On Limited and Additional Liability Companies» provides different rules for withdrawal for a participant from a company that owns less than 50 percent of the share in the share capital and for a participant who owns 50 or more percent of the share in the share capital.It is established that in martial law it is legally possible to enter information into the USR on changes in the composition of participants in connection with leaving the company, but it is prohibited to carry out state registration of transfer of ownership of property to a participant who left the company. However, this restriction does not significantly affect the possibility of withdrawal of the participant from the company, as the company, as a rule, settles with the participant in cash. Replacement of the obligation to pay cash to the obligation to transfer other property can take place only with the consent of the member of the company who left.It is argued that the exercise of the right to withdraw from the company may consist in the possibility of refusing to withdraw from the company. In case of refusal to withdraw from the company, which owns less than 50 percent of the share in the share capital, such a requirement must be properly executed by the application for withdrawal of the application for withdrawal, namely in writing and notarization of the signature of the withdrawing participant. In the case of a member of the company who owns 50 percent or more of the share in the share capital, in addition to the said statement of the participant, consent to withdraw the application to withdraw from the company should be given by participants who have agreed to withdraw. Such consent must also be duly executed. Accordingly, the possibility of withdrawing the application to withdraw from the company must be realized until the actual fulfillment of the company’s obligations.
Development of the conceptual foundations of the ratio of public law to private law in classical German jurisprudence
Authors: Andriiuk V.V.
Published: November 2024

In the article, the author tries to focus on the problem of the evolution of views, ideas and concepts of the relationship between public and private law in classical German jurisprudence, taking into account the active influence of German legal doctrine in the formation of Ukrainian legal opinion on this issue. At the same time, the author attempted a generalized analysis of key theoretical positions in the history of the development of classical German legal doctrine regarding the distinction between public and private law.The author came to the conclusion that for a long time (practically until the end of the 18th century) German legal opinion did not attach any significant importance to the division of law into public and private law, and German legal scholars of that time considered this issue traditionally in line with the ideas formulated by Roman jurists, without succeeding to proper legal argumentation.At the turn of the 18th and 19th centuries, the first attempts to investigate the problem of the relationship between public and private law appeared in German philosophical literature, and later in legal doctrine, which began to develop actively. These subsystems are already considered as autonomous legal entities, because the concentration of political power in the hands of the state and the creation of public law also led to the separation of private law as a separate subsystem of law.In the 19th century, during the formation of classical legal science, German lawyers thoroughly developed the issue of distinguishing public and private law, trying to clearly define its criteria, the ontological essence and methodology of legal regulation within these subsystems, as well as, in general, the transformation and development of positive law in the context of its division on public and private. At the same time, within the limits of the German legal doctrine of this period, a detailed argumentation of the concept of interest, the concept of the subject, the functional concept, the concept of subordination, as well as the mixed approach, which offers a combination of the provisions of these concepts, is proposed.Since the end of the 19th century, under the influence of state intervention in the sphere of economy, active state regulation of social relations, development of concepts of social direction (in particular, the concept of the welfare state), a tendency to interweaving, rapprochement, and convergence of public and private law has been observed in German legal doctrine.
Classification of criminal offenses in the field of economic activity related to the circulation of information
Authors: Solodzhuk V.V.
Published: November 2024

The article analyzes the existing points of view regarding the classification of criminal offenses in the field of economic activity in general and those related to the circulation of information. The discussion revolves, first of all, around the definition of the object of this group of criminal offenses, and since the generic object is one of the criteria used for the classification of criminal offenses, accordingly, the issue of such classification is also not unequivocally resolved. The analysis of the existing classifications of criminal offenses in the field of economic activity allows us to conclude that the relevant criminal offenses, the subject of which is information, may belong to different groups. The main criterion for such classifications is the object of criminal offenses. Any classification is conditional, since criminal offenses in the field of economic activity usually encroach on several specific (direct) objects, and are placed in only one classification group. Within the scope of the study, it is suggested that the distribution of criminal offenses related to the circulation of information in the field of economic activity be carried out as follows: 1) criminal offenses related to the circulation of information in the system of money circulation, the stock market, and the circulation of individual documents (art. 200, 2231, 2321, 2322, 2323 Criminal Code of Ukraine); 2) criminal offenses related to the circulation of information when engaged in economic activity (art. 2051, 2091 Criminal Code of Ukraine); 3) criminal offenses related to the circulation of information in the field of lending (art. 2201, 2202, 222 Criminal Code of Ukraine); 4) criminal offenses related to the circulation of information during fair competition (art. 231, 232 Criminal Code of Ukraine).
