Published: May 2022

The purpose of this research is to examine the variability in yields and yield components of wheat cultivars in Northern Serbia, examine and visualize their groupings and relationships, and determine the correlations between their traits using principal components analysis (PCA). A total of fifteen wheat genotypes (Triticum aestivum L.), developed in 10 different countries over a period exceeding 70 years, were analyzed during the growing seasons of 2018/2019 and 2019/2020 at Rimski šančevi, the experimental station of the Institute of Field and Vegetable Crops in Novi Sad. A phenotypic analysis was performed for the following wheat traits: spike weight, number of spikelets per spike, number of grains per spike, thousand grain weight, and grain yield. Data analysis was performed using descriptive statistics, an analysis of variance, a correlation analysis for interactions between the traits considered, and PCA. The results obtained indicate significant differences between the genotypes according to all the traits examined. The correlation analysis revealed significant positive correlations between the yields produced and nearly all yield components. The PCA confirmed the relationship between the traits examined, grouped the genotypes according to their performance, and highlighted the genotypes eligible for future breeding and research.

Authors: Gosztonyi Márton
Published: May 2022

Objective: In our study, we analyze Central and Eastern European (CEE) scientific papers published in peer-reviewed scientific journals between 2015 and 2021. We examine what category systems and methods are used in Central and Eastern European start-up researches in the recent years.

Methodology: Our used methodology was structured literature review analysis and artificial intelligence-based natural language processing which is one of the most evolving methodological directions in economics and social sciences at present but it is very rarely used in review analysis of startup research.

Value Added: The NLP method has not been widely used for the analysis of the startup literature. Furthermore, our study is the first which analyzes CEE startups research with NLP technique.

Findings: Based on our results, it can be stated that CEE startup researches follow the big global startup research narratives. However, a specific conceptual network is also emerging which contains several shifts of emphasis compared to the directions of global research.

Background: Healthcare Workers (HCW) represent one of the most vulnerable subject groups to be infected by severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2).

Aims: Between March 2020 and May 2020, we decided to implement a surveillance programme for HCW that aimed to (1) strengthen the safety of the employees; (2) estimate the punctual prevalence of SARS-CoV-2 infection in asymptomatic operators; (3) use the results to train personnel and to strengthen surveillance for applying and validating preventive strategies; and (4) compare the observed prevalence and the infection characteristics with a real-life (RL) sample from non-healthcare settings.

Methods: A nasopharyngeal (NP) swab in HCW, representative of all mansions, and RL subjects was performed after informed consent signing (T0), then after 6 d ± 24 h (T1) and after 12 d ± 24 h (T2). The presence of SARS-CoV-2 mRNA was tested by commercially available real-time PCR.

Results: A total of 219 HCW and 100 RL subjects were enrolled; and among all the subjects, only 1 HCW resulted positive at the swab testing throughout the study period. The positive subject was an asymptomatic nurse without any comorbidities or risk factors.

Conclusions: Our experience supports the utility of implementing dedicated surveillance programmes for the HCW. The efficiency in keeping low the number of the infection, maintaining the psychological well-being of the personnel and the availability of a tool which in case of infection may allow the early identification of clusters are critical issues which encourage the planning and implementation of such programmes NIH clinicaltrials.gov (NCT04913701).
The Admission of Baptized Children to Holy Communion before Confirmation Anglican Approaches
Authors: Nichols Bridget
Published: May 2022

The member churches of the Anglican Communion take different approaches to the admission of children to communion before they are confirmed. This article surveys developments in the Church of England, which introduced the practice experimentally in 1996 and gave it official sanction in 2006. Since then, dioceses have developed materials for preparation and training. There is a noticeable emphasis on the meal and community aspects of the eucharist in this provision, which tends to draw rather selectively on Scripture to provide a foundation. More active involvement of biblical scholars, theologians and liturgists would provide balance and depth. In the life of the church, such dialogue might contribute towards more imaginative involvement of children in the eucharist, beyond simply allowing them to be communicants.

Authors: Sescu-Gal Cristina , Savaniu Mihail , Frâncu Cătălin
Published: May 2022

The inspection of bridges is an essential activity to maintain the viability and safe operation of these structures. The inspection process shall be carried out by visual means using special equipment called bridge inspector. The equipment is similar in design to mobile crane installations – crane lorries, with the rotating part in the form of a boom at the end of which is the work platform for personnel and tools. The structure of the arm has the shape of a lattice girder or beams with closed section (caisson); regardless of the type of construction there is at least one telescopable section. During use, the installation is positioned on the superstructure of the bridges, supporting it by means of folding or telescopic outriggers.

Starting from the determination of the loads on the supports of a crane, loads necessary to ensure the stability, in the case study presented in the paper, the authors identify for bridge inspection equipment the value of the loads transmitted through the support system for different positions of the telescopic arm. These values are of interest when, due to space or omission, the outriggers of the installation are positioned on sidewalks or degraded structures and may cause loss of stability leading to technical damage (of the installation and the bridge) but also possible injuries to workers.

Published: May 2022

As the prevalence of social media increases, it is considered as an important promotion outlet for the airline industry. The main motivation behind this paper is to identify the determinants of attitude towards social media advertising in the context of the Turkish airline industry. The model of advertising value lies in the theoretical foundation of this paper. Employing a convenience sampling, a questionnaire was completed by 123 users of social media in Turkey. The Partial Least Squares Structural Equation modeling (PLS-SEM) approach was employed to test the hypothesized relationships. Results revealed that informativeness, entertainment, and credibility are positively associated with advertising value, thus affecting attitude towards social media advertising. On the other hand, irritation has no significant relation with advertising value.
The Move Towards Cashless Society: How to Improve Consumers’ Use of Bank Cards in Retail Stores?
Authors: Aboubaker Ettis Saïd , Mohamed Eldabet Mahmoud
Published: May 2022

The World Health Organization says money can spread all varieties of bacteria and viruses. A measure that can be taken to help stop the spread of Covid-19 is decreasing or ideally, eliminating, the use of cash and promoting the use of contactless payments. Cash remains a frequently used retail payment method specifically for small-value purchases. The switch from cash to cards and other payment methods is one of the major trends in consumer shopping financial behavior. This research investigates explaining factors of bank cards use for payment purposes. It builds on an integration of the Technology Acceptance Model and the Theory of Planned Behavior to explain customers’ intention to use bank cards. Data was collected with a face-to-face survey in retailing context. The proposed model was tested through the PLS-SEM approach. Results show that perceived usefulness, perceived ease of use, subjective norm, perceived behavioral control, and attitude are prominent predictors of the behavioral intention to use bank cards for payment purposes in retail stores. The findings provide insights to service vendors and merchants on how to increase customers’ use of cards rather than cash.

Role of Economic Factors in Property Liability Insurance Consumption: Empirically Examining the Indian Market
Authors: Abhijit Mukherjee , Amlan Ghosh
Published: May 2022

The association of property liability insurance (PLI) consumption with economic growth in the post liberalized era has already been established justifying the need to analyze the economic factors which lead to PLI development. The empirical examination reveals that income and trade development have a positive relation with PLI consumption whereas negative relationship is obtained for interest rate movement and financial development. However, inconclusive relation is derived for infrastructure development and price of insurance. The findings will assist the policymakers, insurance regulator and insurance statutory body in stimulating PLI consumption by focusing on the identified economic factors and devise policies to support the growth in PLI sector.

Determinants Analysis of Islamic and Conventional Banks Systemic Risk Potentiality: A Preliminary Study
Authors: Fitri Rahmadana Muhammad , Hafiz Sagala Gaffar
Published: May 2022

This study aims to analyze the determinants of systemic risk in Islamic and conventional banks. The population of this research is Islamic and conventional banks, which are listed on the Indonesia Stock Exchange. Researchers used purposive sampling to ensure the suitability of the sample with the research objectives. Furthermore, we use secondary data obtained from financial databases such as Yahoo Finance and the Indonesia Stock Exchange. This study adopts the systemic risk measurement offered by Fiordelisi and Marquez-Ibanez (2013). The determinants of systemic risk were explored from the six independent variables, namely the bank efficiency, business model, size, interest rate, GDP, and bank categories (Islamic or conventional). Data analysis was performed with panel data regression. The results indicate that size is the critical factor in determining potential systemic risk for banks, both Islamic and conventional banks. This study contributes theoretically in constructing theoretical frameworks related to the stability and resilience of Islamic banks in comparison with conventional banks. Practically this study seeks to produce recommendations for improvement of Islamic banking financial governance as an alternative to conventional banking.
Non-Oil Sectors, Economic Diversification and Growth in Nigeria: Further Empirical Evidence
Authors: Obafemi Young Ademola
Published: May 2022

The adverse consequences of over-reliance of Nigerian economy on oil has continued to heighten the call and need to diversify the productive base of the economy towards non-oil sectors. To heed the call, successive governments have implemented several economic policies at different periods. However, while the contents of these policies are plausible, the full-anticipated benefits are far from being realized. The disappointing results have been linked to two principal factors: the incoherent implementation of the policies and neglect of the country-specific circumstances. Informed by the need to take cognizance of the country’s peculiar circumstances, the question as to which priority sectors that Nigeria should target for diversification efforts has come up in literature. Empirically, in view of the country’s natural resource abundance, studies have suggested agricultural, industrial and many others non-oil sectors as plausible options for diversifying the economy. In light of this, the study examines the interactions among non-oil sectors, economic diversification and growth in a multivariate VAR model over the period 1960-2019. Empirical results reveal that while an expansion of economic activities into resource-based sectors is a necessary condition for diversification; however, it is not a sufficient condition as the dimension of the diversification matters.
Exploring Romania’s Digital Gap - What is Under the Water, If this is Only the Tip of the Iceberg?
Authors: Claudia Ogrean , Mihaela Herciu
Published: May 2022

Fully committed to a digital future and actively engaged in the transition to a digital economy, the European Union has issued (in March 2021) “2030 Digital Compass: the European way for the Digital Decade’. While setting the EU’s digital ambitions on Skills, Business, Infrastructures, and Public services, the Digital Compass also envisions an enhanced DESI” (Digital Economy and Society Index) to become an official and concerted instrument for monitoring the EU’s progress towards the stated targets. As regards Romania’s digital transformation path (and speed), its persistent lack of DESI performance compared to the EU average raised the question of whether there is something more / deeper that needs be identified, assessed, and properly managed to make Romania fit for the digital age (in general) and to Digital Europe (in particular). Therefore, the paper aims to explore Romania’s digital gap both top-down (via DESI lenses) and bottom-up (up to the “key competences and basic skills” evaluated by PISA, the OECD’s periodic assessment on student performance) - in search of DESI’s (deeper / hidden) determinants / causes needing to be addressed - due to their capacity to impact Romania’s fit for the digital age on the long run.

Object and purpose of research. The object of research is arrangement of various items on the bottom of water bodies. The purpose of research is achieving maximum invisibility for such items. Anticipated search or accidental detection of bottom objects can be carried out by the bathymetric method, i.e. assessment of water column over such objects. Materials and methods. It is expected that low flying UAVs (unmanned aerial vehicles) equipped with bathymetric laser emitter are used for detection of underwater objects. With consideration of some simplifications, optimization is carried out for the operation of bathymetric laser detector of objects located on the sea bed. The task of detecting an underwater object is considered to be solved when the difference between the signals reflected from the sea bed and underwater object is reliably recorded. Minimum external detectability is achieved at minimum of the said difference. Main results. An objective functional is obtained to characterize the total signal from multiple underwater objects. As a result of performed optimization, the condition is determined at which the minimum of the objective functional is achieved. According to the obtained result, the total signal reflected from an underwater object reaches its minimum if the height of underwater objects and their reflection coefficient vary paraphase, i.e. the growth of one is accompanied with the reduction of the other. Conclusion. A method for minimum detectability of objects stacked on the sea bed is suggested and validated. Practical procedures of storing various objects on the sea bed are defined, which ensures their invisibility for the bathymetric laser detector onboard the low-flying UAV.

La voz de los ancestros. El teponaztli de Huatusco, Veracruz
Authors: Escamilla Udave Jorge
Published: May 2022

En la parte central del estado de Veracruz, dominio territorial del coloso Pico de Orizaba, se ubica la ciudad de Huatusco de Chicuellar. En ese rincón de la geografía estatal existe un teponaztli muy antiguo asociado con eventos de trascendencia histórica. De su intervención restaurativa se desprendió un catálogo del manejo y del uso prolongado al que fuera sometido en su larga vida, a riesgo de privarle de su profundo sonido que, sostienen las leyendas locales, podía ser escuchado hasta las faldas del pico nevado y que, por lo mismo, era asociado con la voz de los ancestros. A partir de diferentes fuentes históricas: crónicas, leyendas y testimonios de la tradición oral, nuestro correlato reconstruye su larga vida y el sentido otorgado al teponaztli dentro de la cosmovisión indígena, premisa inspiradora que motivó el esfuerzo por preservarlo como símbolo inequívoco de la identidad huatusqueña actual.
Amazigh in Morocco through the Lens of the U.S. State Departmentâ€™s Reports between 1999 and 2020: A Critical Discourse Analysis
Authors: Laaguid Brahim Ait
Published: May 2022

This paper uses critical discourse analysis (CDA), particularly Theo Van Leeuwenâ€™s socio-semantic inventory, to discover the discursive representations of the social actors in the U.S. State Departmentâ€™s coverage of Amazighsâ€™ struggle for their linguistic and cultural rights in its annual reports on human rights practices in Morocco, between 1999 and 2020. The data comprises 21 texts with 5796 words. These are the content of the â€˜National/ Racial/ Ethnic Minoritiesâ€™ section within the pertinent reports, available on the State Departmentâ€™s online database. The investigated section follows the section of â€˜Persons with Disabilitiesâ€™. The findings show that the Amazigh issue has not been reported with careful attention; inaccurate information has, for instance, been detected. The inclusion representational categories are predominantly used; differentiation and categorization are given special weight, compared to the strategies of genericization, individualization, objectivation, and assimilation. Assigning distinctive prominence to two groups aims to emphasize the persistent â€˜conflictâ€™ in Morocco between the disempowered Amazigh activists and the empowered Moroccan â€˜authoritiesâ€™. The exclusion representational categories, on the other hand, specifically backgrounding and nominalization, are also heavily employed to mystify agency in critical situations, mainly when the related social actors are â€˜the authoritiesâ€™. The study concludes that the representation of the social actors is influenced by the ideological stances and agenda of the U.S. State Department.

The recent COVID-19 pandemic crisis has led to the rapid digitalization which significantly causes changes the labour market structures. Although digitalization is often associated with higher productivity, however, the implications of automation may have some critical challenges to the labour market and future employment. This paper aims to explore the implications that pandemic-induced digitalization may have on the labour market. By employing the systematic literature review approach, this paper will gather the relevant past literature evidences to determine the consequences and economic benefits of the digital transformation that has been triggered by the COVID-19 crisis. The main findings from this review indicated that the pandemic crisis has likely resulted the acceleration of digitalization and changes the nature of work in many occupations. Next, the results of the review further pointed out the implications of digitalization in employment by causing job displacement, resulting youth unemployment, causes diminishing demand for low-skill workers, and increasing inequality. However, there are suggestion that there could be positive benefits from the digital transformation experienced. Hence, a future research is encourage to explore the public policy solutions that can be implemented to support an inclusive and efficient digital transformation.

Published: May 2022

Patients with COVID-19 who are in the ICU considered to be extremely high malnutrition, which is caused by food intake matter and the disease itself. In critically ill, the definition of malnutrition is not only based on weight loss but also muscle wasting, sarcopenia and metabolic dysregulation. Good nutrition management prevents malnutrition getting worse. Nutritional theraphy is an essential element of the patients management.  Nutritional screening and assessment, as well as nutritional management, should be integrated into general therapeutic strategy.  Nutrition theraphy to ICU patients with COVID-19 has been published by some institutions/organizations.

A cross-sectional study on clinical correlates of post-stroke depression in a tertiary health-care system of India
Authors: Samantray Swayanka , Sahoo Srikant Kumar , Mohapatra Hiranmaya
Published: May 2022

Objectives:

The aim of our study is to determine the relation of the type of stroke and site of lesion and medical comorbidities such as diabetes and hypertension with the severity of depression, HAM-D scores as well as age and gender of these patients.

Materials and Methods:

The present study was a hospital-based cross-sectional study conducted over 2 months that included 61 patients from neurology OPD of IMS and SUM Hospital, Bhubaneswar. Purposive sampling was done. The patients fulfilling the inclusion and exclusion criteria were first assessed using a semi-structured questionnaire to obtain the sociodemographic data. Clinical psychiatric evaluation and detailed mental state examination were done. Based on the clinical findings and using ICD 10-DCR criteria, the 61 patients with CVA were segregated as depressive and non-depressive categories. HAM-A and HAM-D scales were applied on both the groups. MRI findings done at the time of the attack were obtained. Further research is needed to identify the mechanisms of depression and why antidepressants lead to improved physical and cognitive recovery and decreased mortality.

Results:

Age of onset, gender, type of stroke and hemispherical involvement do not show any correlation with PSD. However, we found that the HAM-D scores were much higher in PSD patients with lacunar lesions as compared to non-depressive post stroke patients.

Conclusion:

Lacunar lesions may be involved in the psychopathology of depressive illness among stroke survivors. This could help us predict the occurrence of depressive illness among stroke patients with lacunar lesions. HAM-D and HAM-A may be used to detect anxiety and depressive symptoms among these patients.

The school counselling profession has challenges in pandemic or post-Covid-19 pandemic conditions for self-development and alleviation of student problems. Current conditions limit all access to learning as well as GC-S (GC-S). The social media utilization becomes an alternative supporting GC-S. The goal of this research is to evaluate the use of social media by school counsellors to support GC-S in schools. Mix-method research with sequential transformative design through quantitative data backed by qualitative data. The research targets were 90 students and three school counsellors with questionnaires and interviews. Analysis of questionnaire data was quantitative with standard deviation and percentage, and then interview data was descriptive qualitative. The result of the study is that school counsellors have used social media to support GC-S with good categories. School counsellors use two primary social media, namely WhatsApp and YouTube, because of the access and convenience for students, although not all students can interact, discuss, and participate actively. Counsellors need to be more active and creative during a pandemic or post-Covid-19 pandemic in GC-S with various technologies in GC-S.
On Language Equations with One-sided Concatenation
Authors:   Theoretical Computer Science Dresden University of Technology, Baader Franz , Okhotin Alexander ,   Department of Mathematics University of Turku
Published: May 2022

Language equations are equations where both the constants occurring in the equations and the solutions are formal languages. They have first been introduced in formal language theory, but are now also considered in other areas of computer science. In the present paper, we restrict the attention to language equations with one-sided concatenation, but in contrast to previous work on these equations, we allow not just union but all Boolean operations to be used when formulating them. In addition, we are not just interested in deciding solvability of such equations, but also in deciding other properties of the set of solutions, like its cardinality (finite, infinite, uncountable) and whether it contains least/greatest solutions. We show that all these decision problems are ExpTime-complete.

Musical preferences are an extremely complex phenomenon formed under the influence of many factors. The paper investigates whether there are gender- and age-related differences in the preferences of primary school students from Croatia and Bosnia and Herzegovina and whether there is a connection between music familiarity and preferences for certain musical excerpts. To examine students’ preferences for musical excerpts, a general data questionnaire and an assessment scale were administered to a sample of 253 participants, including second, third, seventh, and eighth grade primary school students from Croatia and Bosnia and Herzegovina. The results show gender- and age-related differences in the preferences for classical music, whereby female students, compared to male students, and younger students, compared to older students, show higher preferences for classical music. A significant interaction effect of gender and age on classical music preferences was found. Furthermore, the results show that male and female students do not differ in their preferences for world music, while age-related difference was observed, with younger students, compared to older students, showing greater preferences for this musical style. A significant interaction effect of gender and age on world music preferences was found. Finally, it was confirmed that students show higher preferences for familiar musical excerpts compared to unfamiliar musical excerpts. The obtained results represent a significant contribution to the study of musical preferences from the aspect of music psychology and music pedagogy.
A Mean-Field Model for Oxygen Reduction Electrocatalytic Activity on High-Entropy Alloys

High-entropy alloys (HEAs) represent near-equimolar points in the middle of a vast composition space of multi-metallic catalysts. Successful modeling of the catalytic activity of these complex materials allows to search this composition space for optimal catalysts. Previous models of HEA catalytic activity have been based on local and intricate descriptions of the atomic environment on the catalyst surface to predict accurate adsorption energies. These are subsequently used to model the catalytic activity. In this study, we show that by approximating the ligand effect of the surrounding atoms around an adsorption site with a mean-field perturbation corresponding to equimolar AgIrPdPtRu, the same trend in the predictions of the oxygen reduction reaction catalytic activities are obtained for a majority of the quinary Ag-Ir-Pd-Pt-Ru composition space. By comparing to models that consider the ligand effect locally, we show that the extent of such a mean-field approximation is valid up to and including equimolar ternary alloys, corresponding to 60.3 % of the quinary composition space. When extrapolating to make predictions far from near-equimolar compositions, such as for binary alloys, the mean field has been sufficiently perturbed to cause large discrepancies compared to the local models. Here, the intricate models thus prove more useful for discovering optimal catalysts.

The bis(tert-butylimido)-molybdenum(VI) framework has been used successfully in the design of vapor-phase precursors for molybdenum-containing thin films, so understanding its thermal behavior is important for such applications. Here we report the thermal decomposition mechanism for a series of volatile bis(alkylimido)-dichloromolybdenum(VI) adducts with neutral N,N’-chelating ligands, to probe the stability and decomposition pathways for these industrially relevant molecules. The alkyl groups explored were tert-butyl, tert-pentyl, 1-adamantyl, and a cyclic imido (from 2,5-dimethylhexane-2,5-diamine). We also report the synthesis of the new tert-octyl imido adducts, (tOctN)2MoCl2·L (L = N,N,N’,N’ tetramethylethylenediamine or 2,2'-bipyridine), which have been fully characterized by spectroscopic techniques as well as single-crystal X-ray diffraction and thermal analysis. We found that the decomposition of all compounds follows the same general pathway, proceeding first by the dissociation of the chelating ligand to give the coordinatively unsaturated species (RN)2MoCl2. Subsequent dimerization results in either an imido bridged adduct, [(RN)Mo(μ-NR)Cl2]2, or a chloride bridged adduct, [(RN)2Mo(μ-Cl)Cl]2, depending on the size of the R group. The dimeric species then undergoes an intramolecular γ-hydrogen transfer to yield a nitrido-amido adduct (RHN)MoNCl2, and an alkene. Ultimately, the resulting molybdenum species decomposes into free tert-alkylamine and β-Mo2N. The thermolysis reactions have been monitored using 1H NMR spectroscopy, and the volatile decomposition products were analyzed using gas chromatography–mass spectrometry. A key intermediate has also been detected using electron ionization high-resolution mass spectrometry. Finally, a detailed computational investigation supports the mechanism outlined above and helps explain the relative stabilities of different N,N’-chelated bis(alkylimido)-dichloromolybdenum(VI) adducts.

Natural selection is the cornerstone of Darwinian evolution and acts on reproducing entities exhibiting variations that can be inherited and selected for based on, among others, interactions with the environment. Conversely, the replicating entities can also affect their environment generating a two-way feedback on evolutionary dynamics. The onset of such ecological-evolutionary dynamics marks a stepping stone in the transition from chemistry to biology. Yet the bottom-up creation of a molecular system that exhibits ecological-evolutionary dynamics has remained elusive. Here, we describe the onset of such dynamics in a minimal system containing two synthetic self-replicators. The replicators are capable of binding and activating a cofactor, enabling them to change the oxidation state of their environment through photoredox catalysis. The replicator distribution adapts to this change and, depending on light intensity, one or the other replicator prevails. In both cases the replicator distribution evolves towards higher dynamic kinetic stability, rooted in a faster replication rate under the specific environmental conditions. This study opens the world of chemistry to evolutionary dynamics that has until now been restricted to biology.

Targeted degradation of proteins, especially those regarded as ‘undruggable’, attracts wide attention to develop novel potential therapeutic strategy. GPX4, a key enzyme regulating ferroptosis, is such a target whose inhibition is currently limited to molecules acting through covalently binding. Here, we have developed a targeted photolysis approach to achieve the efficiently degradation of GPX4. The Photo-Degradation TArgeting Chimeras (PDTACs) were synthesized by conjugating a clinically approved photosensitizer Verteporfin to GPX4-targeting peptides. Although the ligands themselves exhibit neither inhibitory nor degrading activity towards GPX4, these chimeras degraded selectively the target protein in living cells upon red-light irradiation. In contrast to the application of Verteporfin alone, the targeted photolysis of GPX4 resulted in dominant ferroptotic cell death in malignant cancer cells of different origins. Moreover, the dying cells resulted from our chimeras exhibited potent immunogenicity in vitro, and elicited more efficiently anti-tumor immunity in vivo in comparison with those dying from Verteporfin. Our approach therefore provides a novel method to dysfunction GPX4 based on noncovalent binding and specifically trigger immunogenic ferroptosis, which may boost the development of triggering ferroptosis as a potential strategy in cancer immunotherapy.
