In Vitro Propagation of Alyssum Species with Different Metal Accumulation Strategies

The Alyssum genus, with its many metal-adapted species, is a good candidate for research on phytoremediation and metal tolerance mechanisms. These goals can be supported by elaborating on an in vitro multiplication protocol. Our study aimed to determine the aseptic conditions for the growth and effective propagation of Alyssum murale, A. alyssoides, and A. montanum, each exhibiting different adaptation strategies to nickel ions. Firstly, hydrogen peroxide (H2O2) or sodium nitroprusside (SNP) were investigated in the biological Lepidium test to find their optimal concentrations that could improve the germination attributes of tested Alyssum species. The concentration of 0.5 mM H2O2 or SNP was selected for research on Alyssum seeds, which were the initial material to start in vitro cultivation. Regardless of the species, H2O2 harmed germination percentage; however, its application accelerated radicle emergence, especially in metal-sensitive genotypes, while in both metal-tolerant ones, the germination time of H2O2-treated seeds was similar to that of treated with SNP. These findings provide a novel insight into the effect of H2O2 or SNP on seeds, contributing to a better understanding of their role in the germination of different genotypes. Among tested media compositions, the synchronous plant regeneration of all species was achieved on MS medium supplemented with 0.5 mg/L 2iP and 0.1 mg/L IAA, making an essential advancement in the in vitro protocols for metallophytes.

Between Consumption and Liberation – A Critical Analysis of Women’s Legal Trajectory of Emancipation, Regulation and Gender Pricing

ABSTRACT Law is always perceived as pivotal to women’s emancipation. Women gaining any form of legal recognition is construed as a step towards gender equality. Therefore, when looking to address issues around gender pricing – charging consumers differently for the same product or service because of their gender – experts turn to law as an obvious solution. Legal scholars suggest anti-discrimination regulation as the answer to liberation, and economists argue women should make better consumer choices. However, neither of these approaches addresses the problem in its entirety. In this article, instead of presenting anti-discrimination as a solution, I take gender pricing as a case study to map the intersection among law, gender, and capital and understand why the law might not be the answer leading women to emancipation. Through Queer Marxist lenses, I start by presenting gender pricing as a burden affecting women in the consumption sphere. In the second part, I focus on consumption and its relevance for the imposition of gendered subjectivities as part of an accumulation strategy. In the third part, I draw a parallel between the stages of women’s emancipation trajectory and the forms of backlash they face in their liberation struggle. As a case study, gender pricing allows me to understand consumption as an instance or site of regulation of gendered identities that goes beyond the formal equality achieved in law. The conception of women as consumers, mainly in the global North, reinforces particular subjectivities according to a historical process and is part of capital accumulation strategies. While corporations profit from gender pricing commodities, women are comparatively impoverished by gender pricing and other economic burdens, thus allowing men to maintain their hierarchically superior economic position.

A Life's Work? Unpacking the Existential Meaning of Educational Mobilities for Migrant Families

ABSTRACTIt is axiomatic that middle‐class Asian migrant families invest heavily—practically and emotionally—in their children's education. Scholarship has linked this investment to strategies of capital accumulation. There has been little discussion, however, about the transformative nature of these strategies and how they might be framed in terms of migrants' whole lives. This paper applies theoretical concepts from migration studies and a framework proposed by philosopher Charles Taylor, to argue that educational migration should be seen as profoundly life shaping.

The phenotypic and demographic response to the combination of copper and thermal stressors strongly varies within the ciliate species, Tetrahymena thermophila.

Copper pollution can alter biological and trophic functions. Organisms can utilise different tolerance strategies, including accumulation mechanisms (intracellular vacuoles, external chelation, etc.) to maintain themselves in copper-polluted environments. Accumulation mechanisms can influence the expression of other phenotypic traits, allowing organisms to deal with copper stress. Whether copper effects on accumulation strategies interact with other environmental stressors such as temperature and how this may differ within species are still unsolved questions. Here, we tested experimentally whether the combined effect of copper and temperature modulates traits linked to demography, morphology, movement and accumulation in six strains of the ciliate Tetrahymena thermophila. We also explored whether copper accumulation might modulate environmental copper concentration effects on phenotypic and demographic traits. Results showed high intraspecific variability in the phenotypic and demographic response to copper, with interactive effects between temperature and copper. In addition, they suggested an attenuation effect of copper accumulation on the sensitivity of traits to copper, but with great variation between strains, temperatures and copper concentrations. Diversity of responses among strains and their thermal dependencies pleads for the integration of intraspecific variability and multiple stressors approaches in ecotoxicological studies, thus improving the reliability of assessments of the effects of pollutants on biodiversity.

Palestine and the Ends of Theory

This article argues that over the past decade-and-a-half, amidst the resurgence of US/EU solidarity with Palestine, several anti-Zionist analyses have emerged that sidestep national liberation, regional politics, or imperialism. It connects that terrain to the rise of a new, and partially anti-systemic, political Islam that gained strength with the fall of the USSR and the contradictions arising within US-led imperialism. The article links this phenomenon to post-Cold War imperialist counterinsurgency and accumulation strategies, and the chasm separating EU-US anti-Zionism from the Palestinian national movement. It discusses political repression and the professionalization of Arab regional studies and ‘the Left,’ with pressures to create a Palestinian narrative speaking to an alleged mainstream and thus making Palestinian rights fit within a world-system and its geoculture that have no place for them. It analyzes those theories that helped forge an anti-Zionism hostile to Israel that ignores, mischaracterizes, or rejects the concrete forces resisting Israel and the US. The article calls for a more catholic theoretical practice that is open to the liberation agenda and its historical agents.

Making profit from energy transition. Political struggles and accumulation strategies in Guadeloupe

ABSTRACT The electricity industry in Guadeloupe has undergone a rapid transition. In this paper we analyse how this energy transition concretely occurred and what are the implications for industrial players and their accumulation strategies? Energy transition policies are configured by political struggles involving power producers (both incumbents and challengers) to ensure their profitability. We focus specifically on financial relationships and circuits underlying the Guadeloupean electricity industry, arguing that the political (de)construction of these circuits by (public and private) actors is key to better understand the transition process and/or its path-dependence. We identify three different and successive sequences of energy transition, from 2000 to 2023, characterized by different financial circuit architectures and distributive outcomes.

Unveiling morphophysiological and metabolic adaptive strategies of the CAM epiphytic bromeliad Acanthostachys pitcairnioides to drought

Ongoing climate changes are expected to intensify drought periods in tropical regions, directly impacting epiphytic bromeliads that depend on intermittent water availability. This study aimed to elucidate if Acanthostachys pitcairnioides, an epiphytic bromeliad of Atlantic Forest, tolerates extended drought periods and the potential strategies involved in its tolerance and recovery capacity. We suppressed irrigation for 42 days, rehydrated plants for four days, and evaluated leaf water status, and photochemical, metabolic, and anatomical changes. During the initial 28 days of drought, translocation of water from hydrenchyma to chlorenchyma, higher chlorophyll content, and accumulation of abscisic and salicylic acid and antioxidants contributed to maintaining the cell turgor and functionality of photosynthetic apparatus. At 42 days, a significant reduction in leaf water content to 45.5% was accompanied by a 2.5-fold increase in non-photochemical quenching and enhanced levels of carotenoids, anthocyanins, osmoregulators (proline, myo-inositol, and trehalose), and phytohormones (abscisic acid and jasmonates). After rewatering, water storage in the hydrenchyma and almost all pigments, hormones, and metabolites were restored to pre-stress conditions. Leaf succulence, carbohydrate and organic acid accumulation, and carbon isotope data (δ13C−14.5‰) provide evidence of induction of CAM metabolism by water limitation in A. pitcairnioides. Our findings indicate the prevalence of water accumulation strategy during the first half of the drought stress. At the end of the drought period, the complete depletion of water from the hydrenchyma favored the osmotic adjustment. Considering this set of tolerance strategies and the rapid recovery after rehydration, A. pitcairnioides can successfully withstand environments with restricted water availability.

Japanese climate capitalism? Toward an understanding of industry’s changing attitudes toward climate change mitigation in Japan

Despite a history of progressive environmental policies in relation to pollution and energy efficiency, Japan stands out as a country with relatively few achievements on the issue of climate change. While research on Japanese climate change policy up until now has focused attention on the role played by government, to date insufficient attention has been paid to the role and impacts of various sectors of Japanese industry in both directly influencing climate change policy and in shaping the discourse surrounding climate change in Japan, as well as to the ways through which the accumulation strategies of different fractions of capital may be impacted by climate change policy. This article overcomes this gap by surveying business responses to climate change and climate change policy through a mixed methods approach that combines content analysis and critical discourse analysis of major firms’ annual corporate reports, comparing data from 2010, the last year prior to the 2011 Great East Japan Earthquake that had highly disruptive impacts on Japan’s power generation capacity as well as the discourse surrounding energy more widely, and 2022, the most recent year for which all firms had data available. The content analysis results indicate a substantial increase in attention to climate change related keywords between 2010 and 2022 across all sectors, but particularly for the oil and gas, electric power, and steel manufacturing sectors. Yet a closer look at some of the detailed comments from key firms indicated an ongoing commitment to continued expansion of output and consumption, with carbon neutrality to be achieved wholly through the application of advanced technologies, many of which are currently commercially or technically unviable, raising questions about many firms’ abilities to effectively achieve their emissions reductions targets without more significant changes to their overall business strategies.

P-221 The efficiency of a PGT-A program is negatively impacted by the utilization of frozen-thawed oocytes in patients of all ages

Abstract Study question Are there any differences in the use of fresh or frozen-thawed oocytes in a PGT-A program? Summary answer While euploidy rates are comparable, the efficiency of a PGT program is adversely impacted when utilizing frozen-thawed oocytes. What is known already Oocyte vitrification has become one of the key assisted reproduction procedures. Some studies have reported rates of embryonic development, clinical pregnancy, and embryo implantation comparable between fresh and cryopreserved oocytes in egg donor patients. Vitrified oocyte accumulation before the blastocyst biopsy is a commonly used strategy in PGT programs to enhance the chances of obtaining a euploid blastocyst with the patient’s own oocytes. Further research is needed to assess the impact of frozen-thawed oocytes on aneuploidy and the efficiency of PGT programs. Study design, size, duration We conducted a retrospective comparison of 777 PGT-A cycles, using either fresh or frozen-thawed oocytes, regarding embryo development (fertilization rates, blastocyst formation, and rates of good-quality blastocysts), PGT outcomes (euploidy and mosaicism rates), and the overall efficiency of the PGT cycle, measured as the number of euploid blastocyst per available mature oocytes, between April 2018 and November 2023. The study groups were stratified based on the age of the patients (≤35 and >35 years old). Participants/materials, setting, methods PGT-A cycles were categorized into two groups: patients who utilized fresh oocytes (n = 641) and those who utilized frozen-thawed oocytes (n = 136). A total of 6,370 fresh oocytes and surviving oocytes from the initially vitrified ones (972 out of 1,153) were fertilized and cultured to the blastocyst stage, at which point biopsies were performed. The biopsied cells were subjected to NGS screening, and statistical data analysis was conducted using the Chi-square test, with significance set at P < 0.05. Main results and the role of chance In the group of patients aged ≤35 years old, significant differences were observed when comparing PGT cycles using fresh or frozen-thawed oocytes in terms of the fertilization rate (78.4% vs. 72.0%), blastocyst formation rate (47.4% vs. 37.7%), and the efficiency of the PGT cycle (24.0% vs. 16.0%), corresponding to a 33.3% reduction in efficiency. No differences were observed between fresh and frozen-thawed oocytes regarding euploidy rate (64.6% vs. 68.4%), mosaicism rate (4.9% vs. 5.1%), and the percentage of good-quality embryos (60.0% vs. 56.1%). Similarly, in patients aged >35 years old, fertilization (81.5% vs. 73.5%), blastocyst formation (40.5% vs. 33.4%), and the efficiency of the PGT cycle (11.7% vs. 7.2%), which correspond to a 38.5% reduction in efficiency, were improved when using fresh oocytes. No differences were observed regarding euploidy (35.6% vs. 35.3%) or mosaicism rate (3.8% vs. 5.3%), and the percentage of good-quality embryos (55.2% vs. 54.7%). The oocyte survival rate was 84.3%. Limitations, reasons for caution Our study is limited by its sample size and retrospective design, as well as the inclusion of a non-selected and general infertile population, which could amplify the impact of confounding variables. Wider implications of the findings We found that the utilization of frozen-thawed oocytes reduces the PGT program efficiency by decreasing fertilization and blastocyst formation rates. This suggests that the oocyte accumulation strategy should be approached with caution. However, vitrification did not lead to an increase in the rates of aneuploidy, mosaicism, or poor-quality blastocysts. Trial registration number NOT APPLICABLE

The South Korean chaebol and myths of green growth: Coloniality and Argentinian lithium production

Observers have celebrated the drive by multinational corporations to develop lithium-ion batteries as a positive step in mitigating climate change. Much of this hype, however, has resulted from corporate leaders propagating green growth narratives that trumpet the capacity of electric cars to initiate an energy transition. Against this backdrop, the paper describes and analyzes significant contradictions of green growth. The South Korean (hereafter, Korea) ‘chaebol’ (enormous, family-owned conglomerates) have deployed green growth myths to build global value chains that transform lithium into batteries that can electrify transportation. I will show how these growth strategies simultaneously produce domestic inequality in Korea and colonial inequities in Argentina, where a large proportion of the world's reserves of lithium lie. Since the 1990s, the chaebol have developed new strategies of accumulation based on a shift toward building global value chains and away from domestic economic growth and expanding employment. The growing electric vehicle industry represents a continuation of these corporate strategies, directing investments to flow abroad in ways that contract domestic employment. These technological innovations require lithium, prompting the chaebols to move decisively to establish control over a significant share of lithium production in Argentina. In seeking to create new pools of value within the much-hyped green transition, these activities have inflicted significant environmental degradation. Moreover, the coloniality of corporate relations with local labor dramatizes how the green transition promised by electric vehicles unevenly distributes the risks and benefits between those parts of the world producing green energy and the industrialized countries consuming it.

"Blood on the floor:" The nickel commodity frontier and inter-capitalist competition under green extractivism

Major companies in the mining industry are strategizing to benefit from the expected rise in demand for energy "transition minerals" that underpin current technologies of decarbonization (such as batteries and wind turbines). This article elucidates their current strategies of accumulation through the case of BHP, the world's largest mining company. We draw on political ecology and commodity frontier theory in order to grapple with inter-capitalist competition under the current moment of green extractivism by examining firm and state practices in the nickel commodity frontier. Empirically, we examine the changing role that nickel has played in BHP's asset portfolio during the past decade where it has attempted to significantly accumulate from the expansion of the nickel commodity frontier. Yet, despite this centering of the expansion of the nickel commodity frontier for its particular strategy of accumulation under green extractivism, it has so far been unsuccessful. Given this potential for failure of company practices in commodity frontiers, we argue that green extractivism should not always and everywhere be seen as a story foretold.

Imperial Past, Neoliberal Present, Dependent Future: A Political-Economic Approach to Urban Development of Bursa

Urban spaces, as the material representatives of past capital accumulation strategies, survive or get replaced on the basis of actors' strategies and partnerships. Periodization allows conceptualising these decisions and subsequent spatial change with respect to evolving local and national settings. The study focuses on expanding such approaches to Türkiye's experience beyond the two primate cities Istanbul and Ankara by the example of a secondary city, Bursa. The study uses maps, plans, official documents and newspapers corresponding to the periods and literature to form the connections between the actors' decisions and the spatial changes. The results highlight that while the previous periods' urban fabric and heritage is being replaced during the neoliberal era in parallel with the national experience, the problems faced as a secondary centre in close proximity to a primate city reduces local agency much more severely, leaving the urban space more vulnerable to exogenous influences.

The power to transform structures: power complexes and the challenges for realising a wellbeing economy

This article draws on different strands of existing scholarship to provide an analytical framework for understanding the barriers to achieving a well-being economy. It explores the interplay between agential and structural power, where some actor-coalitions can reproduce or transform pre-existing structures. Conversely, these structures are strategically selective, favouring some actors, interests, and strategies over others. Making sense of this interplay between agential and structural power, the article introduces the notion of power complexes—time-space-specific actor-coalitions with common industry-related interests and the power to reproduce or transform structures in a given conjuncture. To understand the historical “becoming” of today’s political-economic terrain, the article provides a regulationist-inspired history of the rise, fall, and re-emergence of four power complexes: the financial, fossil, livestock-agribusiness, and digital. They pose significant threats to pillars of a wellbeing economy such as ecological sustainability, equ(al)ity, and democracy. Subsequently, today’s structural context is scrutinised in more detail to understand why certain actors dominate strategic calculations in contemporary power complexes. This reveals strategic selectivities that favour multi- and transnational corporate actors over civil society, labour movements, and public bureaucracies. The article then examines firm-to-state lobbying as a strategy employed by corporate actors within today’s structural context to assert their interests. It presents illustrative cases of Blackstone, BP, Bayer, and Alphabet. Finally, it explores implications and challenges for realising a wellbeing economy based on post-/degrowth visions. It emphasises the double challenge faced by such a wellbeing-economy actor-coalition. On one hand, it has to navigate within contemporary modes of regulation that favour corporate strategies of capital accumulation while, on the other, it must confront the self-expanding and extractive logic of capital. In this context, three key challenges are outlined: the need to form unconventional strategic alliances, operate on various spatial dimensions simultaneously, and institutionalise alternatives to firm-to-state lobbying to influence policymaking.

A novel two-scale nonlinear damage accumulation model for vibration fatigue life prediction

Vibration is the main factor causing high cycle fatigue. The macro-response stress and strain of the structure under the excitation of vibration load are generally in the elastic stage. However, fatigue failure still occurs due to long-term cyclic load, which is unexplainable by the macro-plastic accumulation method. Therefore, a two-scale nonlinear damage accumulation model is proposed for vibration fatigue based on the physical characteristics of multi-scale fatigue damage evolution. In this model, two-scale elastic-plastic constitutive equations based on the equivalent inclusion theory are built, and a two-stage damage accumulation strategy with two critical damages is designed. A resonance fatigue life prediction algorithm is established based on the proposed model, and a validation test is carried out using the cantilever beam made of GH4169 alloy. The results show that the deviation between the vibration fatigue life prediction and test results is within a scatter band of factor 2, indicating that the two-scale nonlinear damage accumulation model is effective in the vibration fatigue region.

Improved consolidated bioprocessing for itaconic acid production by simultaneous optimization of cellulase and metabolic pathway of Neurospora crassa

Lignocellulose was directly used in itaconic acid production by a model filamentous fungus Neurospora crassa. The promoters of two clock control genes and cellobiohydrolase 1 gene were selected for heterologous genes expression by evaluating different types of promoters. The effect of overexpression of different cellulase was compared, and it was found that expression of cellobiohydrolase 2 from Trichoderma reesei increased the filter paper activity by 2 times, the cellobiohydrolase activity by 4.5 times, and that the itaconic acid titer was also significantly improved. A bidirectional cis-aconitic acid accumulation strategy was established by constructing the reverse glyoxylate shunt and expressing the transporter MTTA, which increased itaconic acid production to 637.2 mg/L. The simultaneous optimization of cellulase and metabolic pathway was more conducive to the improvement of cellulase activity than that of cellulase alone, so as to further increase itaconic acid production. Finally, through the combination of fermentation by optimized strains and medium optimization, the titers of itaconic acid using Avicel and corn stover as substrate were 1165.1 mg/L and 871.3 mg/L, respectively. The results prove the potential of the consolidated bioprocessing that directly converts lignocellulose to itaconic acid by a model cellulase synthesizing strain.

A ferroptosis amplifier based on triple-enhanced lipid peroxides accumulation strategy for effective pancreatic cancer therapy

As an iron dependent regulatory cell death process driven by excessive lipid peroxides (LPO), ferroptosis is recognized as a powerful weapon for pancreatic cancer (PC) therapy. However, the tumor microenvironment (TME) with hypoxia and elevated glutathione (GSH) expression not only inhibits LPO production, but also induces glutathione peroxidase 4 (GPX4) mediated LPO clearance, which greatly compromise the therapeutic outcomes of ferroptosis. To address these issues, herein, a novel triple-enhanced ferroptosis amplifier (denoted as Zal@HM-PTBC) is rationally designed. After intravenous injection, the overexpressed H2O2/GSH in TME induces the collapse of Zal@HM-PTBC and triggers the production of oxygen and reactive oxygen species (ROS), which synergistically amplify the degree of lipid peroxidation (broaden sources). Concurrently, GSH consumption because of the degradation of the hollow manganese dioxide (HM) significantly weakens the activity of GPX4, resulting in a decrease in LPO clearance (reduce expenditure). Moreover, the loading and site-directed release of zalcitabine further promotes autophagy-dependent LPO accumulation (enhance effectiveness). Both in vitro and in vivo results validated that the ferroptosis amplifier demonstrated superior specificity and favorable therapeutic responses. Overall, this triple-enhanced LPO accumulation strategy demonstrates the ability to facilitate the efficacy of ferroptosis, injecting vigorous vitality into the treatment of PC.

Emotional Experiences and Their Connection With Coping Strategies During the COVID-19 Pandemic: Gender Differences

The study was conducted in Ukraine during the onset of COVID-19 pandemic. The sample contained 232 individuals. The aim was to study emotional experiences and their connection with coping strategies in the context of gender differences. The research was based on the concept of differential emotions, and on the understanding of the accumulation strategies as a dynamic process, which is determined by personal prepositions and situational factors. Measures used in the study were the Differential Emotions Scale and the Ways of Coping Questionnaire. The growth of negative experiences and stress at the beginning of the pandemic among men and women was confirmed. We described the differences regarding emotions and coping strategies. Women use emotion-focused strategies of social support, strategies of positive reappraisal of the situation, and avoidance, the acceptance of responsibility among women is associated with negative emotions. We found that women more frequently use two or more coping strategies compared to men. A different emotional basis of coping strategies, expressed at high levels of tension among men and women, was revealed. The defined features of coping behavior among men and women may help to determine the main goals for the development of preventive and psychotherapeutic interventions.

Auxetic Structure‐Assisted Triboelectric Nanogenerators for Efficient Energy Collection and Wearable Sensing

AbstractTriboelectric nanogenerators (TENGs) are recognized for energy conversion efficiency and applications including electronics and energy storage devices. This study introduces a groundbreaking development in TENG by incorporating negative Poisson's ratio metamaterials to fabricate auxetic‐assisted triboelectric nanogenerators (Auxetic‐TENG), subversively overcoming the low power density of traditional materials. Subtly, an integrated layer‐by‐layer‐assembly and core–shell accumulation strategy is employed to create a synclastic polytetrafluoroethylene negative friction shell‐skeleton, into which positive Poisson's ratio nature collagen aggregate (CA) foam is inwardly embedded as the positive friction core‐material. Surprisingly, the on‐demand introduction of metamaterials in synergy with CA significantly increases the contact area and mechanical energy absorption of the Auxetic‐TENG under pressure. This enhancement in the conversion efficiency of mechanical to electricity capitalizes on the contraction origins of negative Poisson's ratio metamaterials, integrated with the expansion characteristics of the positive Poisson's ratio materials within the structure, facilitating the synergistic compression of the positive and negative friction stratum. Consequently, Auxetic‐TENG achieves an open‐circuit voltage of 85 V, an overturning four times compared to conventional contact–separation TENG, and a power density of 4.2 W m−2. Application experiments demonstrate the superior performance of auxetic‐TENG under various compression ratios and stress conditions, highlighting its potential for real‐time monitoring in healthcare applications.
