Spiritual Practices and Academic Performance of University Students: Basis for the Formulation of Values Development Instructional Package
Authors: Jr. Alipio Antonio Jr. Anano
Published: January 2025

This study examined the relationship between the level of spiritual practices and the academic performance of
university students in state universities across Samar Island. It also aimed to propose a values development instructional package
for university students. Using proportionate random sampling, the study involved 346 Education students from state universities
on the island. The research assessed the students’ level of spiritual practices and its correlation with their academic
performance. The findings revealed that the overall average level of spiritual practices among students in the four state
universities was 2.238, interpreted as "often practiced." In terms of academic performance, the general weighted average (GWA)
of students was 1.92, equivalent to "very good." Statistical analysis showed a moderate positive relationship between the level of
spiritual practices and academic performance. The computed correlation coefficient (r-value) was 0.290, indicating a linear
association between the two variables. Moreover, the p-value of 0.043 was below the 0.05 level of significance, confirming that
the relationship was statistically significant. These results underscore the importance of fostering spiritual growth among
university students. The study recommends that administrators empower campus ministries to enhance spiritual activities within
the universities, thereby fostering an environment supportive of students' spiritual development. Faculty and staff are
encouraged to actively support these initiatives and engage in values formation programs for students.
Beyond point forecasting: Probability density forecasting of corn yield based on quantile regression forest
Authors: Xiong Tao , Xia Meng , Li Gucheng , Li Jian , Xia Weiyi
Published: January 2025

Crop yield forecasting is crucial for global food security. In this paper, we go beyond traditional point forecasting to examine the probability density forecasting of corn yield using a quantile-based machine learning approach. Leveraging 36 years of county-level panel data that cover 1260 counties in China between 1984 and 2019, we develop a quantile regression forest model, enhancing the traditional random forest by integrating quantile regression, for probability density forecasting of corn yield. Quantile regression and quantile regression neural networks are selected as benchmarks. Thirteen meteorological variables are adopted as predictors, and LASSO is used to examine the importance of each variable. Our results show that all quantile-based models produce good point forecasts, prediction intervals, and probability density curves; in general, we find that quantile regression forest with LASSO is best. We also find that the quantile regression neural network does not perform better than the traditional quantile regression, and LASSO doesn’t improve prediction models much in this context. This paper demonstrates that quantile-based machine learning is a promising tool for probability density forecasting of corn yield — but attention must be paid to the selection of machine learning algorithms and their black box properties.

Esta percepción del docente amerita un posicionamiento en el tiempo-espacio que comprenda dimensiones sociales y éticas con la intención de garantizar la confluencia de diferentes percepciones sobre un mismo ámbito de estudio, en aras de articular la teoría con el desarrollo de experiencias y construcciones únicas insertas en contextos emergentes. El presente artículo muestra la relevancia de la humanización de la praxis universitaria en contextos emergentes desde una mirada metacomprensiva. Se abordan elementos implícitos en la praxis académica, tales como la interformación docente, el conocimiento pedagógico y el docente como sujeto orgánico transformador.
Board governance and ownership structure as mechanisms to oversight earnings management: Insights from an emerging market
Authors: Turshan Mohammed Nader
Published: January 2025

This paper investigates the effectiveness of board governance and ownership structures as mechanisms to mitigate earnings management in Palestinian non-financial firms. By analyzing the relationship between board effectiveness and ownership structure on earnings management across 27 companies listed on the Palestine Stock Exchange (PEX) from 2018 to 2022, the study employs multiple regression analysis to derive its findings. The study concludes that Palestinian non-financial companies participate in earnings management, often shaping financial statements to align with management objectives. Family ownership is identified as the most significant factor in reducing earnings management, as higher family ownership typically involves more oversight of management behavior. Board independence also plays a key role, as independent directors effectively monitor executive activities, enhancing performance. Companies audited by the Big Four experience less earnings management due to the quality audit services provided by these firms. Based on these findings, several recommendations are proposed: companies should increase board independence with a higher proportion of independent directors, reduce board size for improved communication, and ensure productive board meetings through structured agendas. Policies supporting family ownership structures and encouraging institutional investor involvement in governance could further enhance transparency. Additionally, engaging high-quality audit firms should be a priority due to their association with lower earnings management. Future research could explore cross-country comparisons, longitudinal studies on governance changes, sector-specific analyses, and qualitative studies on the motivations behind earnings management practices, providing deeper insights into the relationship between corporate governance and earnings management.
The image of women in the dialect dictionaries of the Prizren-Timok dialect area
Authors: Ilic Mirjana
Published: January 2025

The paper analyzes the image of a woman from the perspective of a patriarchal
language community, which is preserved in the lexicon of archaic
Prizren-Timok dialects, based on a corpus of over one thousand lexemes. The
linguistic worldview is stored in the conceptual structures of lexemes,
where the conceptosphere of a traditionally educated patriarchal man is
outlined through the semantic structure. The analysis shows how much the
social status of a woman, her role in the social community, differs from
that of today, but also points to the former ideal of female physical
beauty, spiritual, psychological and moral characteristics.
Bishop of Shkoder Viktor Mihailovic’s letters to reverend Protopresbyter-Stavrofor Stevan Dimitrijevic
Authors: Andrijasevic Nemanja
Published: January 2025

In 1925, Serbian Orthodox Church Bishop Viktor Mihailovic, Archbishop of
Shkoder, addressed some letters to his former teacher, Professor
Protopresbyter-Stavrofor Stevan Dimitrijevic. In these letters, whose
content has been completely unknown to the public eye, he notifies
Dimitrijevic on the position, circumstances and temptations the Serbian folk
and the Serbian Orthodox believers in Albania under his jurisdiction were
facing. It is revealed that the greatest jeopardy for the Serbian believers
living in the city of Shkoder and its vicinity presented a hostile
environment, famine and malaria. These people endured life in such dire
circumstances primarily out of respect for their ancestors, who had
participated in battle and laid their lives for the liberation of this
territory from the Ottoman Empire, and the wish to keep their graves
untouched. Bishop Viktor expected Protopresbyter Dimitrijevic to draw the
attention of the authorities to this issue, i.e., to appeal to certain
Serbian institutions - the Ministry of Health and the Ministry of Education,
namely - and wealthy individuals to take greater care of the Orthodox Serbs
in order to make their further presence and survival in Shkoder more likely.

Published: January 2025

OBJECTIVE

We investigated associations between per- and polyfluoroalkyl substances (PFAS) and changes in diabetes indicators from pregnancy to 12 years after delivery among women with a history of gestational diabetes mellitus (GDM).

RESEARCH DESIGN AND METHODS

Eighty Hispanic women with GDM history were followed from the third trimester of pregnancy to 12 years after delivery. Oral and intravenous glucose tolerance tests were conducted during follow-up. Plasma PFAS concentrations were measured at the third trimester of pregnancy and first postpartum visit. A linear mixed-effects model was used to analyze associations between PFAS and trajectories of diabetes indicators, adjusted for age, breastfeeding status, daily total calorie intake, and body fat percentage.

RESULTS

Increased 2-(N-methyl-perfluorooctane sulfonamido) acetate level was associated with faster increase in concentrations of fasting glucose (P = 0.003). Increased perfluorononanoate (PFNA) and linear perfluorooctanoate (n-PFOA) concentrations were associated with faster increase in fasting insulin concentrations (P = 0.04 for PFNA; P = 0.02 for n-PFOA) and faster decrease in acute insulin response to glucose (P = 0.04 for PFNA; P = 0.02 for n-PFOA).

CONCLUSIONS

PFAS exposure is associated with glucose intolerance, insulin resistance, and β-cell dysfunction, thus increasing type 2 diabetes risk.

Deubiquitinating enzyme USP2 alleviates muscle atrophy by stabilizing PPARγ
Authors: Yang Shu , Xiong Lijiao , Liao Tingfeng , Li Lixing , Li Yanchun , Kang Lin , Yang Guangyan , Liang Zhen
Published: January 2025

Insulin resistance, a hallmark of type 2 diabetes, accelerates muscle breakdown and impairs energy metabolism. However, the role of Ubiquitin Specific Peptidase 2 (USP2), a key regulator of insulin resistance, in sarcopenia remains unclear. Peroxisome proliferator activated receptor γ (PPARγ) plays a critical role in regulating muscle atrophy. This study investigates the role of deubiquitinase USP2 in mitigating muscle atrophy. Our findings revealed reduced USP2 expression in skeletal muscles of patients with type 2 diabetes. In mouse models of diabetes- and dexamethasone (DEX)-induced muscle atrophy, USP2 expression was downregulated in skeletal muscles. Usp2 knockout exacerbated muscle loss and functional impairment induced by diabetes or DEX. Moreover, skeletal muscle-specific Usp2 knockout further aggravated muscle loss and functional impairment induced by diabetes. Local injection of AAV-Usp2 into the gastrocnemius muscles of diabetic mice increased muscle mass, and improved skeletal muscle performance and endurance. It enhanced insulin sensitivity in diabetic mice, shown by lower fasting serum glucose and insulin levels and better glucose tolerance. Mechanistic analysis showed USP2 directly interacted with PPARγ by deubiquitinating it, stabilizing its protein levels, enhancing insulin signaling and sensitivity, and maintaining muscle mass. Loss of PPARγ abolishes the regulatory effects of USP2 on insulin sensitivity and muscle atrophy. MYOD1 activates USP2 transcription by binding to its promoter region. This study demonstrates the protective role of USP2 in mitigating muscle atrophy by stabilizing PPARγ through deubiquitination, particularly in models of diabetic and DEX-induced muscle atrophy. Targeting the USP2-PPARγ axis may offer promising therapeutic strategies for metabolic disorders and sarcopenia.
A reliable and objective method of measuring soft tissue changes in 2D photographs after distraction osteogenesis in individuals with CL/P
Authors: Bergendal Sterner Annika , Svensson Henry , Becker Magnus , Collander Farzaneh Farokh , Wiedel Anna-Paulina
Published: January 2025

Pre- and postoperative photos to assess results are widely used in plastic and reconstructive surgery, for instance, in patients with cleft lip and palate (CL/P). Evaluations are often performed by assessment panels by viewing the photos. However, these are prone to be subjective. Measurements of soft tissues in photos could be an alternative method but have not been widely used so far. Some patients with CL/P develop a retrognathic maxilla in adolescence, with ensuing Class III malocclusion. In severe cases, distraction osteogenesis (DO) of the maxilla may be indicated. The effect of DO on the facial soft tissues is sparsely reported, perhaps due to the rare procedure. The primary aim of the present study is to provide a reliable and objective method of measuring soft tissue profiles in two-dimensional digital photos. Furthermore, the study aims at assessing changes in soft tissues following DO.
Fourteen patients who had undergone DO at our unit were recruited. Preoperative and postoperative photos were identified, and long-term follow-up photos were taken. Three raters performed measurements of four angles and two distances. Inter- and intra-rater reliability and soft tissue changes were analyzed statistically.
Inter- and intra-rater reliability was high overall for most variables. Two angles related to facial convexity changed significantly. So did the upper lip height.
Soft tissues can be measured with a high degree of accuracy, but further evaluation of the method is necessary. DO causes a favorable increase in facial convexity, and an increased upper lip height.

Authors: Sidoryakina V. V. , Solomakha D. A.
Published: January 2025

Introduction. Detecting oil spills is a critical task in monitoring the marine ecosystem, protecting it, and minimizing the consequences of emergency situations. The development of fast and accurate methods for detecting and mapping oil spills at sea is essential for prompt assessment and response to emergencies. High-resolution aerial photography provides researchers with a tool for remote monitoring of water discoloration. Artificial intelligence technologies contribute to improving and automating the interpretation and analysis of such images. This study aims to develop approaches for identifying oil spilled on water surfaces using neural networks and machine learning techniques.

Materials and Methods. Algorithms capable of automatically identifying marine oil spills were developed using computer image analysis and machine learning methods. The U-Net convolutional neural network was employed for image segmentation tasks. The neural network architecture was designed using the PyTorch library implemented in Python. The AdamW optimizer was chosen for training the network. The neural network was trained on a dataset comprising 8,700 images.

Results. The performance of oil spill detection on water surfaces was evaluated using metrics such as IoU, Precision, Recall, Accuracy, and F1 score. Calculations based on these metrics demonstrated identification accuracy of approximately 83–88%, confirming the efficiency of the algorithms used.

Discussion and Conclusion. The U-Net convolutional network was successfully trained and demonstrated high accuracy in detecting marine oil spills on the given dataset. Future work will focus on developing algorithms using more advanced neural network models and image augmentation methods.

Relationship between deadwood structural diversity and carbon stock along environmental and disturbance gradients in Tropical dry forests
Authors: Masanja Sarafina N. , Shirima Deo D. , Zahabu Eliakimu M.
Published: January 2025

Deadwood is a substantial component of forest ecosystems playing a vital role in maintaining ecosystem health and functioning. However, there is limited information on deadwood stand structure which encompasses attributes such as type, quantities and distribution of deadwood pieces and how it is related to its biomass. This study examined the relationship between deadwood species structural diversity and carbon stock along different environmental and disturbance factors in forest and woodland ecosystems. An agglomerative hierarchical clustering analysis was used to identify species communities, followed by indicator species analysis which was done to determine the species significantly associated with each community. Species richness, evenness and Shannon-Wiener diversity index were calculated to determine deadwood species diversity in both ecosystems. Multimodel inference approach was used to analyse the relationship between deadwood carbon stock and diversity indices, soil properties, climate and proximity to roads and settlements. Three communities were identified from forest ecosystems while four communities were from woodland. Multimodel analysis found a positive significant relationship between deadwood carbon stock and species abundance, Shannon-Wiener diversity, soil moisture and proximity to roads in both ecosystems. These findings provide insights into conservation strategies that prioritize protection and restoration of ecosystems as carbon reservois.

Published: January 2025

Insights into the relationships between tree species and their potential seed dispersers in a specific region are vital for determining spatial distribution and population dynamics that rely solely on natural regeneration. Several factors influence fruit production in trees, and the fluctuations in fruit output directly affects the population and diversity of frugivores in that area. We examined the trees of Melia azedarach to analyse the impact of tree size attributes (diameter, height and crown length) on fruit yield. Furthermore, we observed the seed dispersers to determine their role in fruit removal and dispersal. The average fruit production among sample trees varied from 1.8 × 103 to 1.18 × 105. Out of the 10 bird species recorded, the Hypsipetes leucocephalus (Himalayan Black Bulbul) and Pycnonotus leucogenys (Himalayan Bulbul) were the most frequent visitors and crucial for seed dispersal of M. azedarach. Psittacula krameri (Rose-ringed Parakeets) dropped a significant quantity of fruits below the parent tree, acting as a pre-dispersal seed predator. There were significant variations among species in total visits and estimated endocarp disbursed. Our findings indicate that the tree-size attributes like diameter, height, and crown length strongly affected fruit yield capacity in trees of Melia azedarach. Large trees are likely to be reproductively matured and are prioritising resources for reproduction rather than growth. Native animals, especially birds are facilitating seed dispersal in M. azedarach. The estimated period of the availability of ripe fruits reflects the status of seed predators and seed dispersal. The results ultimately revealed that the animal plant interactions of this study would be vital for ecosystem functioning, habitat rewilding and conservation of the ecosystem through balancing plant-animal mutualism.

In August 2024, the pink hibiscus mealybug, Maconellicoccus hirsutus (Green) (Hemiptera: Coccomorpha: Pseudococcidae), was found in heavy infestations on Albizia julibrissin Durazz. (Fabaceae) and Grevillea robusta A. Cunn. (Proteaceae) in Athens, Greece. This is the first global record of A. julibrissin and the first record on G. robusta in Greece, as hosts of M. hirsutus. All developmental stages: eggs, nymphs, and adult males and females, were present. Honeybees (Apis mellifera L.) were observed actively foraging on the abundant honeydew secreted by the mealybugs. Further research is necessary to assess the potential impact of this invasive pest on host plants in Greece, and the significance of its honeydew as an alternative food resource for honeybees.
Mediation in the Enterprise. A New Approach Needed?
Authors: Broński Włodzimierz , Dąbrowski Marek , Rokosz Marcin , Sławicki Piotr
Published: January 2025

Values set the desired course of action in an enterprise. They are a kind of bonding and expression of the corporate culture, which determines how conflicts are understood, resolved, and managed. A problem that negatively affects the enterprise's productivity is the lack of effective conflict prevention and resolution mechanisms. Thus, mediation as a non-confrontational method of diagnosing and resolving conflicts should be a key element of the corporate culture in the enterprise. Does this mean that a new approach to the institution of mediation is needed? To answer this question, the subject of conflicts in the enterprise is discussed first. Then, the need is indicated to have internal dispute resolution procedures operational in the enterprise, which should also include a system for preventing the occurrence of disputes and dealing with possible court proceedings. In the last part, the issue of the mediator is presented, considering the role that the mediator plays, which is to provide professional assistance in the amicable resolution of disputes arising in the workplace.

Published: January 2025

Objective: To investigate factors associated with bovine mastitis in a Compost Barn system and to use MALDI-TOF mass spectrometry to determine the microorganisms involved in the infection.
 
Theoretical Reference: Mastitis negatively impacts dairy farming. To target control measures efficiently, it is important to assess predisposing factors and identify microorganisms. The MALDI-TOF MS technique can contribute to this.
 
Method: Subclinical mastitis was diagnosed by the California Mastitis Test (CMT), with milk collected from positive teats for microbiological analysis by Gram staining and subsequent identification by MALDI-TOF mass spectrometry. Teats were classified for hyperkeratosis and dirt according to standardized methodologies. The seasonal influence on mastitis was analyzed based on local climate data.
 
Results and Discussion: The prevalence of mastitis in the Compost Barn was 35%, with a higher frequency in the warmer, rainier months. There was an association between the occurrence of mastitis and hyperkeratosis (p<0.000001) and dirt (p = 0.02) in the Compost Barn system. Staphylococcus and Bacillus predominated in cases of mastitis. There was no dependence between the type of microorganism and the degree of subclinical mastitis (p = 0.053).
 
Research implications: The results may contribute to developing efficient strategies to combat and control bovine mastitis in the dairy sector.
 
Originality/value: This study contributes to the literature by showing the association of factors with the occurrence of bovine mastitis on dairy farms in the north of Minas Gerais. Using the MALDI-TOF MS technique, it also contributes to the libraries of microorganisms involved in cases of mastitis. The relevance and value of this research are evidenced by its influence on the decision-making process of dairy farmers.

Published: January 2025

Objectives:
This study aimed to understand the complex relationship between type-2 diabetes mellitus (T2DM) management and cancer, ultimately improving patient care and informing public health.
Methods:
This observational cohort study utilized data from the National Institutes of Health Survey (NIHS) for the years 2022 and 2023, comparing health characteristics, risk factors, and cancer risks between patients with T2DM and healthy controls. Data analysis involved multivariate logistic regression to examine associations between T2DM, its treatments, and the incidence of various cancers, adjusting for confounders such as age, gender, hypertension, and smoking status.
Results:
The findings indicated that T2DM significantly elevated the risk of several cancers, notably pancreatic (OR=24.913), liver, uterine, and rectal cancers. Lifestyle factors such as smoking and electronic cigarette use also showed strong associations with increased cancer risks in diabetic patients. Treatments including diabetic pills and insulin were particularly linked with varying cancer risks, highlighting the complex interactions between diabetes management and cancer development.
Conclusions:
The study underscored a critical need for comprehensive diabetes management that extended beyond glycemic control to potentially include cancer risk monitoring. These results suggested that the interplay between diabetes treatments and long-term cancer risks warrants further investigation to optimize treatment strategies and improve overall patient outcomes in individuals with T2DM.
El arte del contrapunto y la paradoja. Imágenes artísticas de Juan Fernando Herrán, Juan Manuel Echavarría, Clemencia Echeverri, Óscar Muñoz y Doris Salcedo como mementos poético-políticos contemporáneos
Authors: Malagón-Kurka María Margarita
Published: January 2025

This article investigates the fact that alongside their concerns with understanding and confronting traumatic situations in their geographical and historical environments, Juan Fernando Herrán, Juan Manuel Echavarría, Clemencia Echeverri, Óscar Muñoz, and Doris Salcedo coincide in alluding in their works to existential and symbolic dimensions linked to vital and natural cycles. These dimensions suggest significant connections with works and theoretical approaches of previous centuries of the Western tradition, in which special emphasis was placed on the finite conditions of human existence. Such an emphasis simultaneously allowed for an awareness of inexorable aspects of the destiny of every living being and of the possible agency that each being can enjoy during his or her existence.
Un museo para la “Nueva Argentina”. La gestión del Museo Nacional de Bellas Artes durante los gobiernos peronistas, 1944-1955
Authors: Suasnábar María Guadalupe
Published: January 2025

This article analyzes the management of the National Museum of Fine Arts during the first Peronist government in Argentina, under the direction of the art historian and critic Juan Zocchi. I argue for a revised account of the relationships established between the National Museum and the artistic field, and its role within the cultural project of early Peronism. Zocchi's directional tenure has been described by art historians as a “delay” in the modernizing project begun years before. However, a deeper analysis allows us to see a novel project based on a particular understanding of modern art, articulating itself with ideologies of justicialist doctrine, and developing strategies to transform the Museum into a prominent site of Peronism's cultural project.

Poly(heptazine imides) (PHIs), a crystalline subclass of carbon nitrides, have emerged as transformative materials for energy conversion, chemical synthesis, and electrochemical applications. Distinguished by a nitrogen-rich ionic framework, structural stability, and a pseudohexagonal lattice, PHIs serve as ideal platform for single-atom catalysts (SACs), delivering exceptional atomic efficiency, catalytic activity, and selectivity. Their unique structural and electronical properties, including negatively charged sites, promote homogeneous SAC dispersion, enhanced light absorption, and efficient charge transport. Advances in ionothermal synthesis, structural engineering, and heterojunction formation have further elevated their functionality. This review highlights PHIs' versatile applications in photocatalysis, photoelectrocatalysis, and organic photoredox catalysis, specifically water splitting, hydrogen production, oxygen evolution, carbon dioxide reduction, methane oxidation, and ammonia synthesis. By systematically exploring their synthesis, structural properties, and catalytic synergy with SACs, this study underscores PHIs' potential to tackle critical challenges in green technologies, achieving efficiencies comparable to their metal oxide counterparts

Renewable electricity-driven valorisation of glycerol is recognised as an effective and alluring approach to generate high value-added compounds from biomass by-products. Two-dimensional conjugated metal-organic frameworks (2D c-MOFs) are promising for electrocatalysis due to their diverse and predictable structures, high electronic conductivity, and efficient utilisation of well-defined active centers. Herein, we report the first systematic investigation of 2D c-MOFs with Ni-X4 (X = O or N) moieties for glycerol oxidation reaction (GOR) to investigate factors impacting both electrocatalytic activity and selectivity. The study involves [Ni3(HHTQ)2]n (HHTQ = 2,3,7,8,12,13-hexahydroxytricycloquinazoline), [Ni3(HHTP)2]n (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene), [Ni3(HITP)2]n (HITP = 2,3,6,7,10,11-hexaiminotriphenylene), and [Ni3(HATI)2]n (HATI = 2,3,7,8,12,13-hexaiminotriindole), revealing superior GOR performance of Ni3(HHTQ)2. In situ-13C electrochemical nuclear magnetic resonance (NMR) and Raman spectroscopies provide insights into the GOR mechanism and identify Ni-O4 sites as active centers. Theoretical exploration further demonstrates that the high GOR activity of Ni3(HHTQ)2 originates from strong adsorption of intermediates and weak interlayer interactions, which improve the transfer process and overall kinetics. Our research proves the feasibility of exploiting 2D c-MOFs as remarkable GOR catalysts, opening up an inspiring avenue for the elaborate design of advanced electrocatalysts, which is of great significance for the development of renewable energy conversion and storage technologies.

Single-crystalline LiNiO2 (SC-LNO), a high-energy-density Li-ion cathode material, suffers from poor long-term electrochemical performance when cycled above 4.2 V (vs. Li+/Li). In this study, we evaluate this degradation using SC-LNO–graphite pouch cells electrochemically aged within a stressful voltage window (2.5–4.4 V) using a constant-current constant-voltage (CC-CV) protocol. Notable capacity fade was observed after one hundred cycles at C/3 rate, in addition to an increase in the overall electrochemical cell impedance. Operando X-ray diffraction data revealed that, despite no significant long-range bulk structural changes, (de-)lithiation of the aged SC-LNO becomes kinetically hindered after 100 cycles. Aging-induced changes in the short-range structure and charge compensation were evaluated through a multi-model quantitative analysis of the operando X-ray absorption spectroscopy data. While the electrochemical aging did not result in particle cracking, soft X-ray absorption spectroscopy data revealed the reconstruction of the cathode surface to a dense rock salt-like layer after long-term cycling, which acts as a kinetic trap for Li+ diffusion. Therefore, even under stressful conditions, deleterious surface reconstruction is the dominant factor that increases cell impedance and reduces Li+ mobility, which leads to the capacity fade. Cathode surface engineering will therefore be key to improving the long-term electrochemical performance of SC-LNO cathodes.

Cyclopentadienyl (Cp) Ru(IV) quinoline complexes are known for their role in bioorthogonal catalysis within cellular environments, where they use endogenous GSH to deprotect profluorescent and prodrug substrates. However, their reactivity toward GSH and potential for redox-mediated therapies remain underexplored. This study presents RuQ-TARF, a Cp-Ru(IV) complex with a quinoline ligand linked to 2',3',4',5'-tetraacetylriboflavin (TARF) as a redox-active moiety. Its catalytic activity in oxidizing GSH and activating a Pt(IV) prodrug of oxaliplatin was investigated. RuQ-TARF catalyzes the oxidation of GSH to GSSG, improving electron transfer compared to RuQ, its flavin-free analogue. LC-MS analysis showed that activating the Pt(IV) prodrug with GSH produces multinuclear Pt(II)-GS species. RuQ-TARF was additionally evaluated during co-incubation with GSH and NADH under blue light, where NADH enabled faster activation of the prodrug, producing oxaliplatin as confirmed by 195Pt NMR. Cyclic voltammetry showed that linking TARF to RuQ improves the reversibility of redox processes, enhancing catalytic performance and supporting its use in combined GSH oxidation and prodrug activation strategies.
