Published: January 2025

Abstract
One of the most challenging features of textile recycling is the widespread use of mixed fibre blends, which hardens the task of effective separation. A mixture of aqueous sodium hydroxide and a cosolvent was applied to a polycotton pre-consumer fabric to promote the chemical separation of polyester (PES) and cotton (CO). The feasibility of reusing the hydrolytic solutions was tested, where dimethyl sulfoxide (DMSO) and 2-propanol allowed the reusage of the hydrolytic solution for up to 3 consecutive cycles when applied to pristine material. The recovery of pure terephthalic acid (TPA), after treatment at 50 °C followed by vacuum filtration, achieved yields ranging from 65 to 69%. No further purification was required in 75% of the tested conditions. Through this environmentally sustainable procedure, a method was proposed that could facilitate the development of a scalable process for the TPA recovery from polycotton textiles. This approach aims to reduce both textile waste production and the need for the de novo synthesis of TPA.

Abstract
The present study was conducted to adapt the short version of the Santa Clara Strength of Religious Faith Questionnaire into Turkish and to examine the validity and reliability of the scale. This methodological study was conducted between January and May 2024 with 283 individuals aged 18 and older in Turkey. Data were collected online by using “Personal Information Form” and the “Short Version of the Santa Clara Strength of Religious Faith Questionnaire”. It was found that all participants believed in God. According to the study results, item-based content validity index (I-CVI) was between 0.87 and 1.00, and the scale-based content validity index (S-CVI) was found to be 0.98. Factor loadings of the scale items vary between 0.570 and 0.840. Fit indices of the scale were calculated as follows: X
2 = 9.64, df = 4 (p < 0.05), X
2/df = 2.41, RMSEA = 0.071, CFI = 0.99, SRMR = 0.021, TLI = 0.98, RMR = 0.012, AIC = 31.64. The overall Cronbach’s alpha value of the scale was 0.860, and the Omega reliability value was 0.866. Short Version of the 5-item Santa Clara Strength of Religious Faith Questionnaire was validated without any changes to the original form. The Turkish version of the Short Version of the Santa Clara Strength of Religious Faith Questionnaire is a valid and reliable instrument for measuring individuals’ strength of religious faith.

Growth hormone-releasing hormone signaling and manifestations within the cardiovascular system
Authors: Dulce Raul A. , Hatzistergos Konstantinos E. , Kanashiro-Takeuchi Rosemeire M. , Takeuchi Lauro M. , Balkan Wayne , Hare Joshua M. 
Published: January 2025

Abstract
Growth hormone (GH)-releasing hormone (GHRH), a hypothalamic peptide initially characterized for its role in GH regulation, has gained increasing attention due to its GH-independent action on peripheral physiology, including that of the cardiovascular system. While its effects on the peripheral vasculature are still under investigation, GHRH and synthetic agonists have exhibited remarkable receptor-mediated cardioprotective properties in preclinical models. GHRH and its analogs enhance myocardial function by improving contractility, reducing oxidative stress, inflammation, and offsetting pathological remodeling. Studies performed in small and large animal models have demonstrated the efficacy of these compounds in diverse cardiomyopathies, suggesting their potential as promising therapeutic agents. However, the clinical translation of GHRH synthetic analogs still faces challenges related to the route of administration and potential side effects mainly associated with activation of the GH/IGF-I axis. Despite these hurdles, the compelling evidence supporting their role in cardiac repair makes GHRH analogs attractive candidates for clinical testing in the treatment of various cardiac diseases.
School bullying and cyberbullying – associations of student’s roles with social-cognitive and affective reactions
Authors: Knauf Rhea-Katharina , Eschenbeck Heike 
Published: January 2025

Abstract
Bullying is a widespread phenomenon at schools and in digital media. Many adolescents come into contact with bullying and must react to it. Social-cognitive and affective reactions to bullying incidents (SCARB) might determine which roles classmates adopt. The current study investigates school bullying and cyberbullying within the class community on the basis of peer nominations and associates pupils’ roles with self-reported SCARB. Roles were assigned in a sample of 1506 pupils. It was hypothesized that defenders stand out in terms of high levels of empathy, feelings of responsibility and defending self-efficacy as well as low levels of moral disengagement and low apprehensions of negative outcomes of defending. Multilevel analyses controlling for gender and grade showed that defenders especially differed from bullies and reinforcer-bullies in terms of empathy, responsibility, defending self-efficacy and moral disengagement for both forms of bullying. Only moral disengagement differed between defenders and other bystander roles (outsiders, reinforcers) and only for cyberbullying. Regarding apprehensions, only victims of school bullying reported significantly higher levels than defenders. The results suggest that strengthening empathy, feelings of responsibility and defending self-efficacy might be pertinent for reducing bullying behavior and fostering defending behavior. Moreover, counteracting moral disengagement may be relevant to prevent undesirable bystander behaviors such as passivity and reinforcing.

Published: January 2025

Abstract
Research in aging often refers to animal models, particularly C57BL/6J (B6J) mice, considered gold standard. However, B6J mice are distributed by different suppliers, which results in divers substrains exhibiting notable phenotypic differences. To ensure a suitable phenotype of cardiac aging, we performed heart analyses of young (5 months) and old B6J mice (24 months) from two substrains: B6JRj (Janvier) and B6JCrl mice (Charles River). In hearts of both substrains, myocardial fibrosis increased with age; however, only in old B6JRj mice cardiac hypertrophy associated with a decreased ejection fraction was observed. Gene set enrichment analysis in heart tissue using proteomic data revealed different age-associated pathway changes between the substrains, especially in oxidative phosphorylation. Functional assessment of isolated cardiomyocytes verified cardiac impairment during aging in B6JRj mice. Overall, results demonstrate that cardiac aging manifests as a moderate systolic dysfunction in B6JRj mice, while B6JCrl mice display no functional changes with age.
Expectancy-disconfirmation and consumer satisfaction: A meta-analysis
Authors: Schiebler Tom , Lee Nick , Brodbeck Felix C. 
Published: January 2025

Abstract
Expectancy-disconfirmation has been the dominant paradigm to explain the formation of consumer satisfaction for over 40 years. Within this paradigm, it is possible for expectations to have opposing effects on consumer satisfaction depending on the underlying psychological processes presupposed. In general, assimilation processes predict positive effects, while contrast processes predict negative effects. A comprehensive assessment of the empirical evidence for these positions is missing. Hence, we provide a meta-analysis of expectancy-disconfirmation research, using 150 records (N = 58,597), to test the direct effects of perceived performance and performance expectations on consumer satisfaction, while also including disconfirmation as a mediator in each path (using meta-analytical path analysis). We found evidence for an overall positive relationship between expectations and consumer satisfaction (r = .29 [0.24, 0.34]) and no evidence supporting contrast effects. Moderator analyses revealed that the positive correlation between performance expectations and consumer satisfaction was significantly stronger for predictive (vs. normative) expectations, for services (vs. goods), and for cross-sectional (vs. longitudinal and experimental) studies. Furthermore, we found an unexpected downward publication bias, which suggests that the true correlation between disconfirmation and consumer satisfaction is higher than the (already high) estimate we found. We discuss how future research can empirically scrutinize popular practitioner views and promote the development of causal explanations, account for non-linear effects, and elucidate the anomalous publication bias found here.

Published: January 2025

Abstract

Purpose
This study aimed to investigate the role of DNA ploidy and proliferation index in distinguishing ameloblastoma (AB) from ameloblastic carcinoma (AC).

Methods
The study included 29 ACs, 6 conventional ABs that transformed into ACs, and a control cohort of 20 conventional ABs. The demographics and clinicopathologic details of the included cases were summarised and compared. The Ki-67 proliferation index was scored using the QuPath open-source software platform. DNA ploidy analysis was performed using high-resolution flow cytometry.

Results
The cohort of ABs presented at an overall younger age compared to both primary and secondary ACs. There was a statistically significant difference between the median duration of the tumour when comparing primary and secondary ACs, with ACs presenting with longer durations than the AB cohort. All cases of AC showed a relatively high median proliferation index of 41.7%, with statistically significant higher scores compared to ABs. DNA ploidy analysis showed that all cases in the AB cohort were diploid. Two diploid cases of AB that transformed into ACs were aneuploid when the corresponding secondary AC was analysed. Fourteen cases of AC were diploid and 12 were aneuploid, with no statistically significant association found between DNA ploidy status of primary and secondary ACs. A statistically significant difference was noted when the DNA ploidy status of ABs was compared to that of ACs. When comparing the Ki-67 proliferation score of ACs to their DNA ploidy status, no statistically significant association was noted.

Conclusion
DNA ploidy analysis and proliferation index via Ki-67 IHC are useful ancillary tests that may be used to support a diagnosis of AC and may assist in distinguishing between challenging cases of AB and AC.

Published: January 2025

Abstract
Natural and artificial selection in domesticated animals can cause specific changes in genomic regions known as selection signatures. Our study used the integrated haplotype score (iHS) and Tajima’s D tests within non-overlapping windows of 100 kb to identify selection signatures, in addition to genetic diversity and linkage disequilibrium estimates in 9498 sheep from breeds in Ireland (Belclare, Charollais, Suffolk, Texel, and Vendeen). The mean observed and expected heterozygosity for all the sheep breeds were 0.353 and 0.355, respectively. Suffolk had the least genetic variation and, along with Texel, had slower linkage disequilibrium decay. iHS and Tajima’s D detected selection signatures for all breeds, with some regions overlapping, thus forming longer segments of selection signatures. Common selection signatures were identified across iHS and Tajima’s D methods for all breeds, with Belclare and Texel having several common regions under positive selection. Several genes were detected within the selection signature regions, including ITGA4, TLR3, and TGFB2 related to the immune system against endoparasites; DLG1, ROBO2, MXI1, MTMR2, CEP57, and FAM78B related to reproductive traits; WDR70 related to milk traits; SCHM1 and MYH15 related to meat traits; and TAS2R4, TAS2R39, and TAS2R40 related to adaptive traits. In conclusion, our results demonstrated moderate genetic diversity in the sheep breeds and detected and characterized selection signatures harboring genes associated with reproductive traits, milk production, meat production, and adaptive traits such as endoparasite resistance.
Fast estimation of the Renshaw-Haberman model and its variants
Authors: Guo Yiping , Li Johnny Siu-Hang 
Published: January 2025

Abstract
In mortality modelling, cohort effects are often taken into consideration as they add insights about variations in mortality across different generations. Statistically speaking, models such as the Renshaw-Haberman model may provide a better fit to historical data compared to their counterparts that incorporate no cohort effects. However, when such models are estimated using an iterative maximum likelihood method in which parameters are updated one at a time, convergence is typically slow and may not even be reached within a reasonably established maximum number of iterations. Among others, the slow convergence problem hinders the study of parameter uncertainty through bootstrapping methods. In this paper, we propose an intuitive estimation method that minimizes the sum of squared errors between actual and fitted log central death rates. The complications arising from the incorporation of cohort effects are overcome by formulating part of the optimization as a principal component analysis with missing values. Using mortality data from various populations, we demonstrate that our proposed method produces satisfactory estimation results and is significantly more efficient compared to the traditional likelihood-based approach.

Published: January 2025

Abstract
The increasing demand for sustainable and eco-friendly pest control methods has led to a growing interest in the development of novel, plant-based pesticides. In this study, we investigated the potential of nano-emulsions containing plant oils (Portulaca oleracea, Raphanus sativus, and Rosmarinus officinalis) as a new approach for controlling three major pests: Aphis gossypii, Spodoptera littoralis, and Tetranychus urticae. Using ultrasonication, we prepared stable and uniform nano-emulsions characterized by thermodynamic properties, dynamic light scattering (DLS), and transmission electron microscopy (TEM). The results showed that the nano-emulsions were effective in controlling the three pests, with the most potent activity observed against Aphis gossypii. Our findings suggest that plant oil nano-emulsions have the potential to be used as a sustainable and eco-friendly alternative to traditional pesticides. The use of these nano-emulsions could provide a new approach to manage pest populations, reducing the environmental impact of pesticide use, and promoting sustainable agriculture.

Published: January 2025

Abstract

Purpose
Bloodstream infections (BSIs) cause significant morbidity and mortality worldwide. Pseudomonas aeruginosa is an important microorganism in BSIs. The aim of this study was to analyze recent trends in the incidence and resistance rates of P. aeruginosa BSIs in Switzerland and its different linguistic regions.

Methods
This retrospective, nationwide observational study analyzed the incidence (using Poisson regression models) and antimicrobial resistance (using logistic regression models) of P. aeruginosa BSIs in Switzerland from 2010 to 2022.

Results
The annual incidence of P. aeruginosa BSIs in Switzerland increased from 5.5 BSIs per 100,000 inhabitants in 2010 to 7.6 BSIs per 100,000 inhabitants in 2022 (p < 0.001). The incidence was higher in the French-speaking region than in the German-speaking region. The resistance rates increased significantly for cefepime (2.4% in 2010, 8.8% in 2022; p < 0.001), ceftazidime (5.6% in 2010, 9.4% in 2022; p = 0.014), ciprofloxacin (3.3% in 2010, 6.5% in 2022; p = 0.014), and piperacillin-tazobactam (6.4% in 2010, 11.2% in 2022; p = 0.002). No significant trends were observed for carbapenem-, aminoglycoside-, or multidrug-resistant P. aeruginosa. A high incidence was observed in patients ≥ 80 years, whereas resistance rates were high in young patients.

Conclusion
The increase in the incidence of P. aeruginosa BSIs emphasizes the importance of monitoring resistant and susceptible P. aeruginosa BSIs. Compared to the population-weighted mean resistance rates in Europe in 2022, those in Switzerland were lower, but an increase was observed for most antibiotics. The high resistance rates in young patients require further investigation.

Authors: Ulucan Diclehan , Ulucan Oguzhan , Ebner Marc 
Published: January 2025

Abstract
Intrinsic image decomposition has become an immensely studied problem over the last decades. It holds many challenges but also provides large benefits if it can be solved. In this study, we provide a short review of intrinsic image decomposition algorithms, datasets, and applications, while also addressing the challenges of the field. Aside from creating an algorithm for this under-constrained problem, another challenge is to evaluate the performance of the developed methods since there are certain limitations in existing evaluation strategies. Thereupon, we introduce two new error metrics, namely the ensemble of metrics and the imperceptible weighted score. The ensemble of metrics integrates different perceptual quality metrics in scale-space, while the imperceptible weighted score is the modified version of the well-known

$$\Delta E$$

metric. We present the usability of our metrics on two datasets by utilizing various intrinsic image decomposition algorithms.
Solid-state welding of UFG copper rods with conical face by means of friction heat impulse
Authors: Morawiński Łukasz , Jasiński Cezary , Goliński Jacek , Chmielewski Tomasz M. 
Published: January 2025

Abstract
Solid-state friction welding of ultra-fine grained materials (UFG) is a complex process to implement. Exceeding the recrystallization temperature during the process causes degradation of the material’s properties. The process temperature can be reduced by limiting the heat power. Using standard friction welding machines and parameters, it is difficult to achieve an appropriately low heat power. The welding tests of Cu-ETP copper with an UFG structure were carried out on a prototype rotary friction welding machine. It enables welding materials with extremely short friction times and high pressure forces. A given set of non-standard/sharp parameters influences the generated heat power. Its characteristic course is called the friction heat impulse (FHI). The use of FHI allows the energy to be reduced to the minimum necessary to obtain a joint. In order to obtain better joint conditions in a short welding time, a conical surface was used on one of the welded samples. The friction welding tests carried out using the FHI method and a prototype machine showed that the average hardness value of the joints increased slightly from 129 HV0.2 to 130 HV0.2. Additionally, the tensile strength remained at the same level as the UFG base material. The results proved that it is possible to weld UFG copper rods with conical face under recrystallization temperature without any signs of degradation of the UFG structure.
