Forming and microstructural behaviors of high strength low alloy 420 steel sheets formed by single point incremental forming process
Authors: Gandhiraj Vignesh , Chinnaiyan Sathiya Narayanan
Published: February 2025

In this work, the forming behavior of the High Strength Low Alloy (HSLA) 420 steel sheet during the Single Point Incremental Forming (SPIF) process was investigated. The formability is enhanced by increasing the spindle rotational speed, reducing the tool feed and reducing the incremental step-down. A numerical simulation was also performed and the results were compatible with experimental results. The studies are further extended to microstructural analyses. A large dislocation density was obtained due to a high swiveling effect. Therefore, the possibilities of high-angle grain boundaries were increased, which caused an increase in the percentage of ultra-fine grain formation. Hence, the strong texture was obtained by increasing the swiveling effect and the texture components were favored to enhance the formability.
Childhood Maltreatment Experience Within a Patriarchal and Islamic Religious Context: Impacts on Dependent Self-Image of Salar Muslim Women
Authors: Xie Weiyi , Han Xiaoyuan , Emery Clifton R. , Ng Siuman
Published: February 2025

Women who have experienced maltreatment in childhood may be more susceptible to developing a dependent self-image, which can impede their overall well-being and sense of agency. This issue is particularly prevalent among the Salar Muslim women of China, who belong to a national minority and are subject to gender-based oppression within a patriarchal society, with additional challenges within the context of Islamic society. The aims of the current study are twofold: (a) It aims to examine the relationship between patriarchal and religious beliefs and dependent self-image among this often-overlooked population in China—Salar Muslim women. (b) It aims to examine the relationship between childhood maltreatment and the dependent self-image among Salar Muslim women. Two hundred one married Salar Muslim women with a probability proportional to the size sampling approach were recruited in the quantitative survey ( Mage = 34.46, SD = 9.58). Multilevel random effects regression models were conducted. The findings indicate that patriarchal beliefs and intrinsic religious motivation were significantly associated with dependent self-image. Moreover, experiences of childhood maltreatment are found to be significantly associated with dependent self-images in this group, even after accounting for contextual factors such as patriarchal beliefs, religious motivations, and other relevant covariates. This study enhances our understanding of how childhood maltreatment impacts the development of a dependent self-image among women, particularly within the complexities of a patriarchal and Islamic cultural setting. We recommend that future research adopts a more nuanced perspective on women’s self-image development, considering the interplay of childhood experiences and sociocultural contexts.
Capitalism, Competition and Class Conflicts: A Pedagogical Introduction to Marxist Political Economy
Authors: Yadav Srishti
Published: February 2025

This article offers an introduction to Marxian economics for the uninitiated student or instructor. It first places Marxian economics within the surplus approach and ties Marx’s economic analysis with his theory of history, that is, historical materialism. The concepts of class, mode of production and antagonism are introduced. The article then discusses Marx’s analysis of capitalism. This is performed by first introducing the reader to the labour theory of value and then to the circuit of capital. The conflict between capital and labour and the conflict between capital and capital are explored around the question of technological change and innovation. This is followed by a brief discussion of the capitalist crises in the Marxian framework, after which the article concludes by presenting two strands of debate within Marxian economics.
The beauty builder: A genealogical analysis of the production of female power and knowledge in artistic swimming
Authors: Hu Xiaoqian Richard , Yang Yue , Jiang Kaixiao
Published: February 2025

The study adopts a Foucauldian genealogical perspective to examine the transformation of gender discourse in artistic swimming. It highlights the importance of challenging the established gender norms and stereotypes in artistic swimming to promote greater gender inclusivity. By investigating archival documents and media coverages related to artistic swimming, the study unveils two discursive factors that result in the constitution of contemporary female-dominant discourse. First, male discourse has gradually diminished along with the development of the sport. Second, the continuous accumulation of female discourses concerning artistic swimming has produced genealogical knowledge aligned with female swimmers’ physical and aesthetic traits. This knowledge ultimately contributes to the label of artistic swimming as a feminine sport and empowers women within its domain. The genealogical examination reveals the constructive nature and the production of the power/knowledge in artistic swimming and scrutinises the epistemological and historical antecedents of the prevalent stereotype surrounding the swimming pool.
From crisis to care: Redesigning work and jobs for employee well-being in hospitality and tourism
Authors: Bansal Anjali , Mukherjee Shreya , Prayag Girish
Published: February 2025

Embedded in Job Characteristics Theory, this study explores the impact of crisis-specific HR practices, particularly job and work redesign, on employee well-being and retention in the Hospitality and Tourism (H&T) sector. Through qualitative interviews with 31 HR managers from hotels, restaurants, travel agencies, and other service organizations, the study reveals key HR practices that led to positive outcomes for both employees and organizations during crises. The findings emphasize the critical distinction between job redesign and work redesign interventions. Organizations that implemented a strategic blend of top-down job redesign and bottom-up work redesign—actively involving both management and employees—achieved better results in fostering employee well-being and retention. This research extends Job Characteristics Theory by highlighting the importance of tailoring HR practices to the unique challenges faced by the H&T sector during crises. Moreover, it underscores the value of aligning job and work design strategies to create holistic solutions that address both structural and individual needs. The study offers actionable insights for H&T practitioners, such as adopting flexible work arrangements, providing skill development opportunities, and leveraging virtual or gamified work engagement techniques. These approaches ensure long-term benefits for employees and organizations by promoting adaptability, engagement, and resilience during challenging times.
The European dimension in education in Hungarian primary school geography textbooks
Authors: Béres András , Hont Zsanett , Molnár-Kovács Zsófia
Published: February 2025

Despite Hungary's nearly quarter-century membership in the European Union (EU), less than half of its citizens hold a positive mental image of the EU. Education plays a crucial role in fostering and reinforcing a sense of European identity and awareness among students, with textbooks serving as key tools in shaping students’ understanding of European values, citizenship, and identity. This study aims to assess how European identity is represented and integrated into contemporary Hungarian primary school geography textbooks within the framework of the European dimensions in education. In the Hungarian public education system, only textbooks that have been prepared by the state may be ordered from the lists of textbooks for use in state schools. Consequently, these textbooks are significantly dependent on the National Core Curriculum (NCC), as they must comply with its standards, although differences in proportions may occur. The study employs content analysis to evaluate the reflection of European identity in regulatory documents (NCC, framework curricula) and across different grade levels and textbook versions, with a particular focus on the incorporation of the European Dimension in Education (EDE) indicators (Ledic et al., 2016). The textbooks were subjected to a systematic review to ascertain their implementation of EDE indicators. The findings suggest that while the textbooks adequately address European topics, they lack sufficient depth and thought-provoking content to effectively foster the development of European awareness and identity. There is a lack of consistency in how European social diversity and pluralism are presented across different textbook versions. Nevertheless, specific elements of European citizenship, such as consumer rights, are presented only superficially and require further attention. Moreover, deficiencies are observed in the discussion of the European Union and its democratic nature. A decline in the proportion of European content in the geography curriculum has been observed since 2000. Moreover, in the introductory section of the NCC 2020, the term “Europe” is no longer explicitly mentioned, in contrast with its presence in previous curricula. The study offers recommendations, including the enhanced integration of EDE indicators into geography textbooks to promote intercultural understanding and active citizenship. Additionally, the incorporation of interactive elements, such as QR codes, could enhance student engagement and facilitate the cognitive processing of geographical data. By improving these areas, educators can better prepare students for an increasingly interconnected and diverse European environment.
How to conduct a meta-analysis in hand surgery. Part II: heterogeneity and publication bias
Authors: Rosales Roberto S , Ruettermann Mike
Published: February 2025

This is the second part of a two-part article on pitfalls in meta-analysis in hand surgery. The purpose of this second part is to introduce the concepts of heterogeneity and publication bias and to describe how these problems should be analysed and addressed when conducting meta-analyses in hand surgery. Statistical heterogeneity, which occurs when the variability in the observed effect cannot be explained by sampling variability alone, may be caused by clinical heterogeneity, methodological heterogeneity or both. A common error in hand surgery meta-analyses is the failure to adequately investigate the sources of heterogeneity. Heterogeneity is also associated with publication bias. Understanding heterogeneity in published meta-analyses would help in the understanding of the available evidence in Hand Surgery.
Spontaneous retroperitoneal hemorrhage due to rupture of a renal angiolipoma in a 37-week pregnancy: a case of Wünderlich syndrome
Authors: Rodríguez Albarracín Mario , Agudelo Cañon Kelly , Montoya Hurtado Laura , Manrique Porras Brenda
Published: February 2025

Introduction

Wünderlich syndrome is defined as spontaneous, non-traumatic retroperitoneal bleeding, often associated with the rupture of a renal angiomyolipoma. Though rare, this condition is life-threatening if not treated promptly. The syndrome is particularly uncommon during pregnancy, posing significant challenges in diagnosis and management due to overlapping symptoms with other obstetric emergencies.

Case Presentation

We report the case of a 25-year-old woman at 37 weeks of gestation who presented to the emergency department with hypovolemic shock, left flank pain, and fetal bradycardia. A large retroperitoneal hematoma was discovered during an emergency caesarean section, later identified as secondary to a ruptured renal angiomyolipoma. Despite the critical presentation, a total nephrectomy was performed successfully, and both mother and child had favorable outcomes.

Conclusion

This case highlights the importance of considering Wünderlich syndrome in differential diagnoses of acute abdominal pain during pregnancy, especially in the presence of shock and renal masses. Prompt interdisciplinary management is crucial for positive maternal and fetal outcomes.
Gastric mucormycosis in a cat
Authors: Mavilio Emilio , Bottero Enrico
Published: February 2025

Case summary

This report describes a case of gastric mucormycosis in a young Ragdoll cat with a 5-day history of vomiting. Physical examination detected mild dehydration and tenderness was elicited on abdominal palpation. The results of blood work-up and radiographic study were unremarkable; however, abdominal ultrasonographic examination revealed multiple hyperechoic neoformations at the level of the pyloric antrum, which were confirmed on endoscopic examination. Non-septate hyphae of irregular diameter with a branched appearance were observed on cytology, and histological examination revealed severe diffuse necrotising and granulomatous gastritis with the presence of intralesional fungal hyphae indicative of mucormycosis, which was confirmed by PCR tests. Antifungal therapy with ketoconazole in addition to supportive treatment temporarily improved the clinical condition. Lethargy, fever and abdominal effusion developed in the following days. Cytological examination of abdominal fluid was compatible with septic peritonitis and, given the severity of the condition, euthanasia was opted by the owners. Post-mortem examination confirmed septic peritonitis resulting from perforation of the gastric wall at one of the neoformations of the pyloric antrum.

Relevance and novel information

To the authors’ knowledge, this is the first reported case of gastric mucormycosis in a cat. Previous literature includes a case of mucormycosis in a Persian cat affecting only the duodenum. In both the Persian cat and the cat described here, gastrointestinal mucormycosis disease progressed rapidly and was fatal.
Non-isothermal spreading and solidification of a molten droplet on solid substrates: An experimental and machine learning-based study
Authors: Hemmati Parnian , Subramanian Santoshi , Yan Peiwen , Kavehpour Pirouz
Published: February 2025

Understanding the dynamics of non-isothermal droplet spreading is critical for various industrial applications, including turbine blade cooling, biodiagnostics, and aerospace manufacturing. This study investigates the behavior of molten droplets impacting cold solid substrates, where simultaneous spreading and solidification occur due to heat exchange. Traditional analytical and numerical methods often fall short in accurately predicting key outcomes such as arrested diameter ([Formula: see text]) and contact angle ([Formula: see text]), largely due to oversimplified assumptions that neglect complex dynamics like viscous dissipation and solidification effects. Here, for the first time, we employ machine learning (ML) models to develop a predictive framework for nonisothermal droplet spreading. A comprehensive dataset was generated from 100 controlled experiments, capturing the effects of varying temperature gradients and flow rates on droplet behavior. Ensemble ML models, including Extra Trees Regressor, Random Forest, Gradient Boosting, and AdaBoost, were trained and evaluated using input features such as temperature, flow rate, and material properties. The AdaBoost model demonstrated superior performance with [Formula: see text] and the lowest error metrics, effectively capturing the complex, nonlinear relationships in the dataset. A comparison with traditional analytical models highlights the ML approach’s enhanced predictive accuracy, providing a novel, data-driven tool for applications in surface coating, soldering, and microfabrication.
How LGBTQ + adults’ experiences of multiple disadvantage impact upon their health and social care service pathways in the UK & Ireland: a scoping review
Authors: Adley Mark , O’Donnell Amy , Scott Stephanie
Published: February 2025

Background

Despite increased awareness of the significant health and healthcare inequalities experienced by minoritised groups, limited research considers the interaction of multiple domains of social disadvantage. This review therefore sought to explore how LGBTQ + adults’ experiences of homelessness, substance use, and criminal justice involvement impact upon their access to and use of health and social care services in the UK and Ireland.

Methods

A qualitative scoping review was conducted in accordance with the PRISMA-ScR framework. Electronic database and web searches identified 26 eligible peer-reviewed and grey literature documents published between 2010–2024. The data were charted, coded, and knowledge gaps identified.

Results

Data were coded thematically, clustered around the concept of normativity. Descriptive qualitative techniques were applied to explore how this was enacted and experienced. Synthesis across the literature identified experiences of discrimination and anticipated stigma that acted as barriers to accessing and engaging with services.

Conclusions

Structural normativity and the privilege afforded to hegemonic population groups impacted upon this population’s access to and use of services. The review adds depth and context to questions around the lack of visibility or engagement in services by LGBTQ + people with experience of disadvantage, and contributes to the wider literature on improving service access for marginalised, underserved, or disadvantaged communities.
Whole-exome sequencing identifies distinct genomic aberrations in eccrine porocarcinomas and poromas
Authors: Puttonen Maya , Almusa Henrikki , Böhling Tom , Koljonen Virve , Sihto Harri
Published: February 2025

Background

Eccrine porocarcinoma (EPC) is a rare malignant skin tumor arising from the eccrine gland. Investigations into the genomic landscape of EPC have uncovered potential drivers of its development and progression. However, there is limited information on the discrepancies between EPC and its benign counterpart, eccrine poroma (EP).

Methods

Formalin-fixed paraffin-embedded (FFPE) samples from 15 EPCs and 5 EPs were retrieved from Helsinki Biobank and Finnish Clinical Biobank Tampere. One EPC was found to be digital papillary adenocarcinoma in review of diagnoses. Whole-exome sequencing was used to conduct a comprehensive analysis to elucidate the genomic features of EPCs and EPs.

Results

There was general heterogeneity within EPCs and EPs, with discrepancies such as exclusive TP53, NCOR1, and CDKN2A mutations in EPCs and a higher mutational load in EPCs than in EPs. Furthermore, we identified alterations in pathways associated with cell adhesion and the extracellular matrix in EPCs, while pathways associated with ketone body and amino acid metabolism were altered in EPs. The MAPK and Ras signaling pathways were enriched in genes mutated only in EPCs.

Conclusions

EPCs and EPs are generally heterogeneous tumor entities with a few distinct discrepancies from each other. The findings from this study emphasize the need to further verify the roles of disrupted genes and pathways in the initiation and progression of EPCs and EPs.
CAR-macrophages targets CD26 to eliminate chronic myeloid leukemia stem cells
Authors: Guoyun Jiang , Yuefeng Qin , Zhenglan Huang , Zuowei Yuan , Hongyan Zhou , Ying Yuan , Wenli Feng
Published: February 2025

Background

Chronic myeloid leukemia stem cells (CML-LSCs), which exhibit resistance to tyrosine kinase inhibitors (TKIs), are the leading cause of treatment failure and recurrence in chronic myeloid leukemia (CML). This highlights the urgent need for novel therapies aimed at eliminating these CML-LSCs. Chimeric antigen receptor macrophages (CAR-M) not only perform phagocytosis on target cells but also function as antigen-presenting cells, thereby activating the anti-tumor immune response.CD26 (dipeptidyl peptidase 4, DPP IV) is abundantly expressed in CML-LSCs and functions as a tumor-specific antigen (TSA) in CAR-M treatment. The purpose of this study is to evaluate CAR-M’s efficacy in targeting CD26-positive CML cells and to develop a novel strategy for CML treatment.

Methods

CD26 CAR-M was constructed using mouse-derived macrophage Raw264.7 cells. CD26 was overexpressed in CML cell lines BP210 and BP210-T315I. The targeting phagocytosis of CAR-M was verified using confocal microscopy and flow cytometry. X-ray was used to eliminate the tumorigenicity of CAR-M, and the safety of CAR-M was verified through CCK-8, clone formation assays, and animal experiments. To assess the anti-leukemia ability of CAR-M in the CML mouse model, the survival, peripheral blood white blood cell counts, and CML cell infiltration in the liver, spleen, and bone marrow (BM) were measured. Additionally, CD26 CAR-THP1 was constructed, and its phagocytic ability against CD26-positive cells NCI-H2452 was confirmed by confocal microscopy.

Results

We successfully constructed CD26 CAR-M and validated its targeted phagocytosis of CD26-positive CML cells both in vitro and in vivo. The data indicate that CAR-M has higher phagocytic efficiency in CD26-positive CML cells than in CD26-negative cells. CAR-M-treated CML mice demonstrated extended survival and reduced CML invasion. In addition, CAR-THP1 demonstrated targeted phagocytosis of NCI-H2452 cells that normally express CD26.

Conclusion

This study demonstrates that CD26 CAR-M effectively targets and phagocytizes CD26-positive CML cells, implying that targeting CD26 with CAR-M could be a viable method for eradicating CML-LSCs. Furthermore, our discoveries illuminate the potential application of CAR-M in treating hematological malignancies.

Mutations in CHRNE encoding the epsilon subunit of acetylcholine receptor result in impaired neuromuscular transmission and congenital myasthenic syndrome (CMS) with variying severity of symptoms. Although the pathophysiology is well-known, blood biomarker signatures enabling a patient-stratification are lacking. This retrospective two-center-study includes 19 recessive CHRNE-patients (AChR deficiency; mean age 14.8 years) from 13 families which were clinically characterized according to disease severity. 15 patients were classified as mildly and 4 patients as moderate to severely affected. Seven known pathogenic and one unreported variant (c.1032 + 2_1032 + 3delinsGT) were identified. Biomarker discovery was carried out on blood samples: proteomics was performed on white blood cells (WBC; n = 12) and on extracellular vesicles (EV) purified from serum samples (n = 7) in addition to amino acid profiling (n = 9) and miRNA screening (n = 18). For miRNA studies, 7 patients with other CMS-subtypes were moreover included. WBC-proteomics unveiled a significant increase of 7 and a decrease of 36 proteins. In silico studies of these proteins indicated affection of secretory granules and the extracellular space. Comparison across patients unveiled increase of two vesicular transport proteins (SCAMP2 and SNX2) in severely affected patients and indeed EV-proteomics revealed increase of 7 and decrease of 13 proteins. Three of these proteins (TARSH, ATRN & PLEC) are known to be important for synaptogenesis and synaptic function. Metabolomics showed decrease of seven amino acids/ amino acid metabolites (aspartic and glutamic acids, phosphoserine, amino adipate, citrulline, ornithine, and 1-methyhistidine). miRNA-profiling showed increase miR − 483 − 3p, miR-365a-3p, miR − 365b − 3p and miR-99a, and decrease of miR-4433b-3p, miR-6873-3p, miR-182-5p and let-7b-5p in CHRNE-patients whereas a comparison with other CMS subtypes showed increase of miR − 205 − 5p, miR − 10b − 5p, miR-125a-5p, miR-499-5p, miR-3120-5p and miR − 483 − 5p and decrease of miR − 1290. Our combined data introduce a molecular fingerprint on protein, metabolic and miRNA level with some of those playing different roles along the neuromuscular axis.
Economic freedom, economic sustainability, and herding behavior: Does the ubiquity of information communication technology matter?
Authors: Saadaoui Mallek Ray , Albaity Mohamed , Rahman Mahfuzur
Published: February 2025

This study investigates the impact of information communication technology (ICT), economic freedom, and economic sustainability on herding behavior, and examines whether the link between economic freedom and economic sustainability depends on ICT. Using quantile regression on a sample of seven Gulf Cooperation Council stock markets from 2004 to 2020, we find that ICT and economic freedom reduce herding in lower quantiles while promoting it in higher quantiles. Conversely, open market freedom and economic sustainability appear to correct herding in all quantiles. The results show that ICT reinforces the move away from herding seen with economic freedom for the transmission channel of ICT on herding. However, ICT plays a dual role in open market freedom and economic sustainability, weakening (strengthening) the curative effect of economic sustainability (open market freedom) in the lower quantiles and strengthening (weakening) it in higher quantiles. Thus, the highest impact in reducing herding exits through the combination of ICT and economic freedom is skewed to the lower quantiles with ICT-open market freedom and skewed to the upper quantiles with ICT-economic sustainability. These results offer substantial implications for policymakers.

Published: February 2025

Background

Cancer-therapy related cardiac dysfunction (CTRCD) remains a significant cause of morbidity and mortality in cancer survivors. In this study, we aimed to identify differential plasma proteins and metabolites associated with left ventricular dysfunction (LVD) in cancer patients.

Methods

We analyzed data from 50 patients referred to the Cleveland Clinic Cardio-Oncology Center for echocardiograph assessment, integrating electronic health records, proteomic, and metabolomic profiles. LVD was defined as an ejection fraction ≤ 55% based on echocardiographic evaluation. Classification-based machine learning models were used to predict LVD using plasma metabolites and proteins as input features.

Results

We identified 13 plasma proteins (P < 0.05) and 14 plasma metabolites (P < 0.05) associated with LVD. Key proteins included markers of inflammation (ST2, TNFRSF14, OPN, and AXL) and chemotaxis (RARRES2, MMP-2, MEPE, and OPN). Notably, sex-specific associations were observed, such as uridine (P = 0.003) in males. Furthermore, metabolomic features significantly associated with LVD included 1-Methyl-4-imidazoleacetic acid (P = 0.015), COL1A1 (P = 0.009), and MMP-2 (P = 0.016), and pointing to metabolic shifts and heightened inflammation in patients with LVD.

Conclusion

Our findings suggest that circulating metabolites may non-invasively detect clinical and molecular differences in patients with LVD, providing insights into underlying disease pathways and potential therapeutic targets.

Authors: Lundh Hannah , Arvidsson Daniel , Greven Christian , Fridolfsson Jonatan , Börjesson Mats , Boman Charlotte , Lauruschkus Katarina , Lundqvist Stefan , Melin Karin , Bernhardsson Susanne
Published: February 2025

Background

Physical activity (PA) in childhood is critical for establishing a healthy lifestyle across the lifespan, particularly to treat and prevent obesity. This study aimed to explore PA and sedentary behaviour (SED) in 6–12-year-old children with obesity and their parents, and possible associations in these behaviours between children and parents.

Methods

Children referred to outpatient paediatric healthcare for obesity treatment and one of their parents wore accelerometers (Axivity) on their hip during seven consecutive days. Accelerometer data were processed using the 10 Hz frequency extended method. Correlations between child and parent PA and SED, respectively, were analysed using intra-class correlation coefficient.

Results

Thirty-nine children (19 female) and 38 parents (20 female) were included. The mean age of the children was 9.7 years (SD 2.0) and the mean parent age was 42.2 years (SD 6.1). The mean child BMI-SDS was 3.0 (SD 0.4). Fifty-seven % of the parents were born in Sweden, 16% in other European countries, and 27% outside Europe. Children spent an average of 9.8 h/day in SED, while parents spent an average of 12.3 h/day. The mean daily time spent in low-intensity PA was 3.9 h for children and 3.4 h for parents, while moderate-to-vigorous intensity PA averaged 0.7 h/day for children and 0.3 h/day for parents. Only six of the children (15%) reached the recommended minimum of 60 min of moderate-to-vigorous intensity PA per day and only two parents (5%) reached the recommended weekly minimum of 150 min of moderate intensity PA. Child and parent SED was significantly correlated, although the correlation was weak (ICC 0.14; p = 0.017). No statistically significant correlations were found for any of the analysed PA intensity levels.

Conclusions

The findings indicate an association between children’s and parents’ SED in this sample of school-aged children with obesity, while no association was observed in PA behaviour. Generalisability of our findings is limited and more research is needed– in larger samples, other settings, and using longitudinal designs– to better understand the potential links between the PA patterns of children with obesity and that of their parents.
Confirmatory Factor Analysis and Propensity to Cheat Scale Validation in the Ethiopian Public Higher Education Institutions
Authors: Taye Dame , Semela Tesfaye , Assefa Samuel
Published: February 2025

Background This study was primarily intended to validate a comprehensive and psychometrically acceptable measure of students’ propensity to cheat (PTC) behavior among undergraduate students in Ethiopian universities by assessing their engagement in different types of cheating behavior. Methods The present study employed an explanatory research design using a questionnaire based on the Propensity to Cheat Scale (PCS). The questionnaire was administered to 500 university students (male = 367 [73.4%]; female = 133 [26.6%]) selected from three Ethiopian public universities between November and January 2022. In order to measure the underlying variables of propensity towards cheating, a factor model is developed using exploratory factor analysis (EFA), and confirmatory factor analysis was employed to validate the students’ perceived PTC. The internal consistency of the PTC scale was assessed using reliability analysis, and validity evaluations were conducted to confirm the scale’s discriminant and convergent validity. Results Confirmatory factor analysis (CFA) results revealed a good fit to the data, and the internal consistency of the PCS was found to be strong, providing a reliable measure of students’ propensity for cheating. Validity evaluations, including discriminant validity and convergent validity, confirmed the validity of the scale. The average variance extracted (AVE) and composite reliability values also supported the scale’s convergent validity. The multidimensional concept of the PTC was supported by a four-factor solution consisting of 26 reliable and valid items. Conclusion The findings of the study demonstrate that the scale has also provided sufficient evidence of convergent and discriminant validity. By establishing discriminant and convergent validity, as well as reliability, through different validation procedures, the study has provided strong evidence for the effectiveness of the PCS as an instrument for determining whether university students are likely to engage in cheating behavior.

Authors: Julian Nikhil , Walia Apoorva , Shetty Tejaswini , Mala Kundabala , Thomas Manuel S
Published: February 2025

The shift towards conservative, adhesive, post-endodontic ceramic restorations represents a significant advance in restorative dentistry. By focusing on minimally invasive techniques and the use of adhesive materials, clinicians can achieve better long-term outcomes in terms of tooth preservation, function and aesthetics. The key lies in the careful assessment of each case, ensuring that the chosen restoration aligns with the principles of biomimetic dentistry, which seeks to restore the tooth in a manner that closely mimics its natural form and function. The purpose of this case series is to underscore the significance of adhesive post-endodontic ceramic restorations in the rehabilitation of the form, function and aesthetics of mutilated posterior teeth.

CPD/Clinical Relevance: The use of conservative posterior indirect adhesive restorations can enhance the long-term survival of endodontically treated teeth.

Published: February 2025

This report describes the case of a patient with Sjögren's syndrome who presented with acute suppurative parotitis. A microbiological test of the purulent discharge obtained from the right parotid duct revealed the condition was secondary to acute Candida infection of the parotid gland. Candida infection of the salivary glands is typically only reported in immunocompromised patients and those with diabetes. In this case, the infection persisted after the initial flucloxacillin prescription, but was later resolved after the patient was given fluconazole for 7 days.

CPD/Clinical Relevance: This case highlights relevant considerations when patients with a high risk of oral candidosis present with acute sialadenitis

Hypercholesterolemia is often considered a major cause of death globally, including in Malaysia, resulting in fatalities due to heart attack or stroke. Recent research indicates that consuming coffee may lower the risk of heart failure and stroke by reducing cholesterol level. The present study investigated the efficacy of consuming Liberica coffee pulp yoghurt in female rats with hypercholesterolemia. 30 rats were divided into six different groups: a control group (GC), negative control groups (NC), a positive control group treated with simvastatin (20 mg/kg) (PC), a low dosage treatment group (8.6 mg/kg) (T1), and a high dosage treatment group (25.7 mg/kg) (T2). All rats were fed a high-cholesterol diet and received treatment daily for 8 weeks. At the end of week 8, all rats were culled. The blood and organs were obtained for biochemistry tests. The results showed that the body and organ weights of GC, PC, T1 and T2 groups show less compared to NC group. The lipid profile shows a significant (P <0.05) increase in NC group compared to other groups. Total cholesterol (TC), triglycerides (TG) and low-density lipoprotein (LDL) levels in NC group show higher among all the groups. T2 group shows significantly (P <0.05) the lowest in TC, TG and LDL levels. Liver and kidney profiles showed no significant changes. The liver histology of the NC groups showed the presence of ballooning cells compared to the other groups. Visceral fat also showed significant hyperplasia in NC group. Overall, this study demonstrated the effectiveness of L.coffee pulp yoghurt at the highest dosage able to reduce hypercholesterolemia.

La cultura visual digital, como los videojuegos, y los dispositivos que la desarrollan, la distribuyen y la ejecutan están realizados en un contexto concreto el cual les impregna no solo de una forma de ver y pensar el tiempo presente, también el tiempo pasado. La recepción y el consumo de estas obras de cultura visual digital son, en muchas ocasiones, vehículos de conciencias históricas concretas. En este artículo vamos a tratar de responder a la pregunta ¿los medios hegemónicos de la cultura visual digital portan una conciencia concreta de la Edad Media? ¿Y de ser así, cuáles son sus causas y consecuencias? Apoyados sobre las obras de Sergio Martínez Luna, Juan Martín Prada y José Luis Brea para examinar la cultura visual contemporánea; las reflexiones acerca de nuestra conciencia histórica elaborados por François Hartog, Hans Ulrich Gumbrecht y Hartmut Rosa; y nuestro propio acervo investigador fruto de nuestra trayectoria investigadora intentaremos ofrecer una respuesta adecuada a la cuestión planteada.

The precise determination of the tectonic deformation timing such as thrust emplacement has always been a challenge for understanding the evolution of fold-and-thrust belts. In the Catalan Coastal Ranges, this issue has traditionally been addressed through the mapping and the analysis of the syn-tectonic successions preserved in the SE margin of the Ebro Basin. However, the age of the Paleogene contractional structures located towards the hinterland and responsible of the inversion and uplift of the inherited Mesozoic structure remained uncertain due to the lack of preserved syn-kinematic strata in these areas. With the aim of better understand the contractional evolution of the area during the Paleogene, this work presents a tectono-stratigraphic analysis approach that combines structural reconstructions, provenance analysis and magnetostratigraphic dating in well-exposed synorogenic sediments in the central SE margin of the Ebro Basin. The results of the study allow to establish the precise age of the main contractional structures present in the central Catalan Coastal Ranges. The combined analysis has revealed that: 1) the inversion of the Montmell-Vallès Faults System started in the Bartonian and continued up to the late Priabonian, and 2) the emplacement of the Gaià-El Camp Thrust and the formation of the Cabra-Carme Anticline took place from early to late Priabonian and was the responsible of the sudden increased of the sedimentation rates. A later decrease of the sedimentation rates during late Priabonian (chron C15n) has been interpreted as the prelude of the end of the Paleogene compressional phase in the area.
The role of traditional commercial spaces in urban evolution: a morphological study of the medina of Tlemcen

Traditional commercial spaces in Islamic cities, particularly souks in Maghreb medinas, have been fascinating urban fabrics in terms of continuity and change of economic activities and urban morphology. The commercial district of Tlemcen, a medieval medina, followed a pattern worth exploring. Therefore, this article examines how changes and growth in urban morphology can affect Tlemcen’s commercial district in terms of distribution and redistribution of activities, transformation of streets, and growth and location of stores. Indeed, the concentration of specialized streets, with chains and networks of stores offering similar items, has been continually affected by their changing positions within a constantly evolving morphological system.
The idea put forward is that although the layout of the traditional commercial district has changed throughout time and space, the commercial pattern has continued to evolve and adapt around its key axes, while maintaining the character of the medina. This research also highlights these spaces’ symbolic and cultural values, as well as their role in preserving urban identity and collective memory. Thus, an urban morphology analysis was conducted to verify this hypothesis by comparing urban patterns from medieval to present. This research is also based on the fieldwork consisting of participant observations and semi-structured interviews.

Utilizing nonlinear interferometers for sensing with undetected light enables new sensing and imaging techniques in spectral ranges that are difficult to detect. To enhance this method for future applications, it is advantageous to extract both amplitude and phase information of an object. This study introduces two approaches for synthetic quantum holography with undetected light, which allows for obtaining an object’s amplitude and phase information in a nonlinear interferometer by capturing only a single image. One method is based on quasi-phase-shifting holography using superpixel structures displayed on a spatial light modulator. The other method relies on synthetic off-axis holography implemented through a linear phase gradient on a spatial light modulator. Both approaches are experimentally analyzed for applicability and compared with available multi-acquisition methods.

Most steelhead trout hatcheries increase growth rate during rearing to produce and release yearling smolts for harvest augmentation, but natural steelhead exhibit variable age of smoltification, so this common rearing practice may not be ideal for programs focused on recovering imperiled wild stocks; therefore, it is important to investigate and compare alternative hatchery rearing methods that promote life history diversity. Over six consecutive years, the Winthrop National Fish Hatchery on the Methow River, WA reared and released paired groups of age-1 (S1) and age-2 (S2) steelhead smolts. To understand how the two rearing methods affected developmental ontogeny and life-history, fish were sampled prior to hatchery release for factors associated with smoltification (size, gill Na+/K+ ATPase activity, and a qualitative smolt phenotype) and sexual maturation (sex, pituitary and testis mRNA transcripts, gonadosomatic index, and plasma 11-ketotestosterone). Our objectives were to quantify levels of smoltification and male maturation during hatchery rearing, combine metrics to estimate residualism (failure to migrate upon release), and compare the treatments by sex. Overall, S2 rearing produced 7.8% more smolts and 44-fold (4.4 vs. 0.1%) more precociously mature males than S1 rearing. Conversely, S1 rearing produced 31.6% more residuals than S2 rearing. While the proportion of total male residuals was comparable between treatments, the S1 treatment produced approximately five-fold more female residuals (20.6 vs. 4.2%). Because residuals contribute minimally to adult returns and the number of returning adult females is critical to the success of salmonid supplementation efforts, developing rearing techniques that maximize migration in females is a management priority. Physiological assessments are useful for characterizing and quantifying the effects and risks of different hatchery rearing regimes on steelhead life-history, in addition to providing sex-specific guidance to inform and optimize conservation management goals in supplementation programs.
