Authors: Han Mi Ah , Kim Hae Ran , Yoon Sang Eun , Park Sun Mi , Kim Boyoung , Kim Seo-Hee , Kim So-Yeong
Published: February 2024

Purpose: Cancer is the leading cause of death in Korea, leading many investigators to focus on cancer research. We present the current practice of variable selection methods for multivariate analyses in cancer studies recently published in major oncology journals in Korea.Methods: We included observational studies investigating associations between exposures and outcomes using multivariate analysis from 10 major oncology journals published in 2021 in KoreaMed, a Korean electronic database. Two reviewers independently and in duplicate performed the reference screening and data extraction. For each study included in this review, we collected important aspects of the variable selection methods in multivariate models, including the study characteristics, analytic methods, and covariate selection methods. The descriptive statistics of the data are presented.Results: In total, 107 studies were included. None used prespecified covariate selection methods, and half of the studies did not provide enough information to classify covariate selection methods. Among the studies reporting selection methods, almost all studies only used data-driven methods, despite having study questions related to causality. The most commonly used method for variable selection was significance in the univariate model, with the outcome as the dependent variable.Conclusion: Half of the included studies did not provide sufficient information to assess the variable selection method, and most used a limited data-driven method. We believe that the reporting of covariate selection methods requires improvement, and our results can be used to educate researchers, editors, and reviewers to increase the transparency and adequacy of covariate selection for multivariable analyses in observational studies.
Adherence to the International Committee of Medical Journal Editors–recommended gender equity policy in nursing journals listed in MEDLINE or PubMed Central:
a descriptive study
Authors: Ko Eun Jeong , Jeong Geum Hee
Published: February 2024

Purpose: The evolving landscape of nursing research emphasizes inclusive representation. The International Committee of Medical Journal Editors (ICMJE) has established guidelines to ensure the fair representation of various demographic variables, including age, sex, and ethnicity. This study aimed to evaluate the adherence of nursing journals indexed in MEDLINE or PubMed Central to the ICMJE’s directives on gender equity, given that journals indexed in MEDLINE and PubMed Central typically adhere to the ICMJE’s guidelines.Methods: A descriptive literature review methodology was employed to analyze 160 nursing journals listed in two databases as of July 28, 2023. The website of each journal was searched, and the most recent original article from each was selected. These articles were then evaluated for their alignment with the ICMJE guidelines on gender equity. Descriptive statistics were applied to categorize and enumerate the cases.Results: Of the articles reviewed from 160 journals, 115 dealt with human populations. Of these, 93 required a description of gender equity. Within this subset, 83 articles distinguished between the genders of human subjects. Gender-based interpretations were provided in 15 articles, while another 68 did not offer an interpretation of differences by gender. Among the 10 articles that did not delineate gender, only two provided a rationale for this omission.Conclusion: Among recent articles published in the nursing journals indexed in MEDLINE and PubMed Central, only 16.1% presented clear gender analyses. These findings highlight the need for editors to strengthen their dedication to gender equity within their editorial policies.
Analisis Pengaruh Variabel Nilai TIU, TWK, Dan TKP Terhadap Kelulusan SKD Pada Tes CPNS Menggunakan Analisa Bivariat Sederhana
Authors: Andy Hermawan  , Aji Saputra
Published: February 2024

This study aims to assess the impact of the General Intelligence Test (TIU), National Insight Test (TWK), and Personal Characteristics Test (TKP) on the success of the Basic Competency Selection (SKD) for Civil Servant Candidate (CPNS). Using data from participants in the Ministry of Law and Human Rights' SKD selection in 2023, we employed univariate analysis, simple bivariate analysis, and binning methods to comprehend variable relationships. Results reveal non-normal distributions for TIU, TWK, and TKP scores, highlighting the intricate nature of distribution in CPNS selection. While a positive correlation exists between variable values and total SKD score, binning analysis emphasizes TKP competitiveness over TIU and TWK scores. These findings offer practical insights for SKD participants to prepare effectively, with a focus on TIU, TWK, and TKP. Additionally, they contribute to transparency and effectiveness in the CPNS selection process. Further studies are recommended to explore additional factors, like age and gender, for the development of more holistic and accurate selection methods. This research supports enhancements in the adaptive and efficient CPNS SKD selection system.

Published: February 2024

The nature and manner in which structures are collapsing in Nigeria are alarming. It creates a room in which structural engineers, the building industry, government, estate developers, building consultants and other relevant stakeholders in the department building industry ask many questions about how and what is behind the sudden collapse of structures. Therefore, this research aimed to predict the ultimate bearing capacity of the square, strip and circular footing from shearing strength parameters using ANN and ANFIS. This paper, 200 data sets were used to develop the model; 75% were used for training and 25% for testing the model. ANN and ANFIS learning algorithms were employed in developing the models under various foundation types. Eventually, Various error measures, such as coefficient of determination (R2), root mean square error (RMSE), mean absolute error (MAE), and correlation coefficient (R), were employed to compare the efficiency of the models. The performance comparison findings indicated that the soft-computing system is an efficient instrument for risk reduction in soil engineering projects. The models were validated using external data and the correlation prediction capacity of the models where ANN-STRIP (89%), ANN-SQUARE (83%), ANN-CIRCULAR (89%), ANFIS-STRIP (86%), ANFIS-SQUARE (79%) and ANFIS-CIRCULAR (96%). All the models have shown a quite good and reliable prediction capacity, with ANFIS-CIRCULAR having 96% prediction accuracy of soil bearing capacity.Keywords: Neural network, neuro-fuzzy, cohesion, angle of internal friction
Integrating business and liberal arts within a Cambodian higher education institution: Insights from action research
Authors: Polley Nathan , Polley Gina
Published: February 2024

This study applied a framework previously established in a Cambodian secondary education institution using an action research methodology to develop and deliver an online and face-to-face course in a Cambodian public university during and after COVID-19 lockdowns in 2020 and 2021. The course sought to integrate business and liberal arts through enquiry-based learning to help learners explore the history and development of business through various art movements and social lenses. Findings from focus groups in this action research study suggest that integrated business-liberal arts education can be effective in creating holistic learning but requires Cambodian educators to consider the teaching context and scaffold the learning, particularly for critical thinking and research. Recommendations are made to strengthen the future delivery of this course and other courses delivered in Cambodian higher education.

Empresas humanas, la nueva normalidad
Authors: Naranjo Picones Carla Elisa
Published: February 2024

La pandemia ha impulsado un cambio radical en las prácticas laborales, llevando a las empresas a volverse más humanas y adaptarse a la "nueva normalidad". El trabajo remoto ha facilitado la contratación global y ha generado desafíos tecnológicos y socioemocionales para los empleados. Las empresas deben apoyar a su personal y adoptar estructuras colaborativas, abandonando las jerárquicas. Estos cambios plantean interrogantes sobre el futuro de las empresas y el trabajo en equipo, pero también brindan oportunidades de crecimiento y cuidado mutuo. La solidaridad y colaboración manifiestas han fortalecido las relaciones laborales. Podemos concluir que las empresas tuvieron que adoptar muchos cambios con la llegada de la pandemia. Si les quedó de otra o no, es algo en lo que diversos autores difieren, aunque definitivamente al adoptar todas estas medidas en las que apoyan al empleado y se preocupan por su salud mental al igual de que cumplan sus objetivos, definitivamente las hizo más humanas.
El Consejo de Seguridad de la ONU frente al equilibrio de poder global contemporáneo
Authors: Mejía Mejía Kenny Gustavo
Published: February 2024

El Consejo de Seguridad constituye la piedra angular de la arquitectura de seguridad internacional. Este órgano del sistema de Naciones Unidas posee la misión central de asegurar el “mantenimiento de la paz y seguridad internacionales”. Desde su creación constituyó el reflejo del equilibrio de poder del periodo de posguerra, dotando a los vencedores de la segunda guerra mundial del estatus de miembros permanentes con poder de veto en las decisiones del Consejo, lo que les aseguró un rol protagónico en el sistema internacional de forma duradera. Durante estas más de siete décadas después de la creación del Consejo de Seguridad el mundo ha experimentado profundas transformaciones dando lugar al surgimiento de potencias emergentes que cada vez ocupan un papel más significativo en el escenario internacional. Frente a estas nuevas realidades, el Consejo de Seguridad ha permanecido inalterable, a pesar de las numerosas demandas de reformas que han formulado muchos Estados. Al analizar los indicadores económicos, demográficos y militares de los miembros permanentes (Estados Unidos, China, Rusia, Reino Unido de Gran Bretaña e Irlanda del Norte y Francia) en comparación con los países miembros del denominado G-4 (Brasil, India, Japón y Alemania) se puede determinar que el equilibrio de poder contemporáneo no se ve reflejado de manera completa en la actual estructura del Consejo de Seguridad. Estas potencias emergentes deben adquirir el estatus de miembros permanentes para aumentar la legitimidad del Consejo y su capacidad de representar de forma efectiva los intereses globales.

This study investigates the benefits of incorporating board games into the elementary English language subject, highlighting their ability to improve vocabulary, and pronunciation skills while promoting critical thinking, teamwork, and social interaction. By examining the positive impact of board games on language acquisition, educators can better understand the potential of this playful approach to enhance elementary studentsâ€™ English language proficiency and overall learning experience through a board game.
Cloud Adoption in Accounting Information Systems in Asia & SOC 2® Report – An Empirical Study on Industry’s Perspective
Authors: K. Makhija Anil
Published: February 2024

ABSTRACT Many business and technology organizations see cloud adoption and migrating existing systems to the cloud as an accelerator of digital transformation. The benefits of cloud adoption are perceived as increased scalability and cost reduction. At the same time, there are concerns about whether the information on cloud-based systems is secure and whether the privacy of the data in a cloud environment is at risk. This research brings out the industry’s perspective, both from an end-user perspective as well as IT transformation and IT procurement decision makers of accounting information systems and enterprise resource planning systems in Asia geography, on the preference for cloud-based or on-premise systems, top enablers for cloud adoption and importance of SOC 2® as an assurance for information security and data privacy concerns. The findings of this research indicate that decision-makers for IT transformation and IT procurement prefer cloud-based accounting information systems and enterprise resource planning systems over on-premise systems. Scalability, cost reduction, business agility, business continuity and disaster recovery, and enhanced collaboration are top enablers for cloud adoption. This research also indicates that the SOC 2® report is increasingly seen to address information security and data privacy concerns.

Use of Game-Based Learning Tools in Management Classes: Students’ Perception and Effects on Their Academic
Authors: Cadungog-Uy Juliet
Published: February 2024

ABSTRACT The game-based learning tool Kahoot promoted an interactive teaching methodology and was found to work best in enhancing students’ motivation and participation. The present study evaluated whether Kahoot improves not only students’ motivation, participation, and academic performance. The study participants were two cohorts of accounting students who studied at CamEd Business School in Cambodia in different semesters. Cohort 1 attended fully online classes, and Cohort 2 attended hybrid courses. The perception survey showed that both groups liked Kahoot activities. It increases class attendance and motivates students to engage in class. However, on the perceived advantages of Kahoot, the cohorts’ perceptions differ significantly, with Cohort 1 being very satisfied while Cohort 2 was satisfied. The analysis of the student’s exam scores showed that their English proficiency contributed 5 percent and 9 percent, respectively, to the variation of the Kahoot scores of the two cohorts. Further, analysis of the correlation results showed that Kahoot scores accounted for 36 percent of the variability in quiz scores, 7 percent in mid-term exam scores, and 1 percent in the final exam scores of Cohort 1. For Cohort 2, Kahoot scores accounted for 52 percent of the variability in quiz scores, 23 percent in mid-term exam scores, and 15 percent in the final exam scores. Considering the timeline when the respondents took the quiz, mid-term and final exams, it is concluded that Kahoot reviews effectively improved exam scores within the short span after the review. The effectiveness, however, wanes after the lapse of time and may not support long-term retention of the lessons.

Parenting Styles and Psychological Distress in CamEd Students
Authors: Cornet Adriaan
Published: February 2024

ABSTRACT Psychological distress in students remains a worrying problem globally, especially during the COVID-19 pandemic. This study aims to analyze psychological distress in students from CamEd Business School and its relationship with the parenting styles of parents of these students. The relationship between psychological distress and parenting styles and the influence of traditional Asian culture on both is analyzed in the literature review. One hundred sixty-four respondents scored the Perceived Stress Scale and the Parental Authority Questionnaire to measure psychological distress and parenting styles, respectively. Scores of the PSS were compared with norm scores by One sample t-test. We conducted independent sample t-tests to analyze gender differences and regression analysis to examine the relationship between parenting styles and psychological distress. The results show a significantly higher amount of psychological distress (M=22.43) in this population than in norm groups (M= 19.63). The female gender was linked with significantly higher amounts of psychological distress than the male gender. This study found no significant correlation between parenting styles and psychological distress. The paper discusses the limitations and implications of these findings. However, we need further research on variables in psychological distress and parenting styles for this population. Keywords: Psychological distress; Students; Parenting styles; Asian culture
Interpedicular approach in percutaneous sacroplasty for treating pain due to direct invasion of rectal cancer into the S3 body: a case report
Authors: Yeo Jinseok , Kim Saeyoung , Lee Chang Sub
Published: February 2024

Percutaneous sacroplasty is mainly used as an intervention for pain associated with sacral insufficiency fractures or sacral metastatic tumors. However, sacroplasty for managing the pain associated with direct sacral invasion of rectal cancer has been rarely reported. We present a case of a 74-year-old patient who underwent sacroplasty via the interpedicular approach under fluoroscopic guidance to relieve pain resulting from direct tumor invasion into the S3 body. After the procedure, the patient experienced immediate pain relief and did not feel worse pain with ambulation. Aside from peritumoral vascular leakage, no other significant complications occurred immediately post-procedure. Our results suggest that fluoroscopically guided interpedicular sacroplasty is a safe and effective option for relieving the pain associated with direct sacral invasion by rectal cancer.
Les représentations d’une région française durant l’entre-deux-guerres dans la revue La Bretagne touristique (1922-1939) : quel portrait de pays ?
Authors: Bougeard Christian
Published: February 2024

La Bretagne touristique, publication mensuelle lancée le 15 avril 1922, devenue Bretagne en 1929, est la création d’un homme Octave-Louis Aubert, journaliste-éditeur installé à SaintBrieuc (Côtes-du-Nord, Bretagne). Par sa revue illustrée d’une riche iconographie dans laquelle la photographie occupe une grande place et au régionalisme revendiqué, Aubert veut promouvoir la Bretagne dans tous les domaines — économiques et touristiques bien sûr, mais surtout littéraires et artistiques —, en défendant les traditions bretonnes tout en associant modernisation et modernité. Des écrivains connus appuient cette initiative. Les reportages photographiques et textuels dressent le portrait d’une région à la forte identité régionale qui s’efforce de préserver sa langue celtique, le breton, ses coutumes et ses traditions en valorisant son patrimoine et son passé, mais qui aspire aussi à se moderniser. En même temps, surtout dans les années 1930, la revue fait connaître les jeunes créateurs bretons (écrivains, poètes, peintres, sculpteurs, graveurs, musiciens) en publiant leurs écrits ou en reproduisant leurs oeuvres. Le dépouillement des 173 numéros parus durant l’entre-deux-guerres montre que La Bretagne touristique forge des représentations du « pays breton », cette « petite patrie » qui veut préserver son identité régionale dans le cadre de la « grande patrie » française, après les sacrifices de la Première Guerre mondiale.
Ecophilosophy as a Way of Life
Authors: Mathews Freya
Published: February 2024

The contemporary figure of the ecophilosopher perhaps holds the seeds of something that transcends philosophy in its current strictly academic, professionalized, indeed corporatized mode. This is a "something" that could, on the one hand, tie philosophy back to its own ancient, life-giving, but now lost, root in the Graeco-Roman world, and on the other hand, open it up to people searching outside the academy for a shared and reflective way of life that is authentically Earth-aligned. By means of a detailed comparison of ecophilosophy with the ancient schools of Stoicism and Epicureanism, understood not merely as intellectual discourses but as "ways of life" (Pierre Hadot), I argue that the figure of the ecophilosopher potentially offers to thoughtful people everywhere a radical pathway through the illusions of our current period of decline-and-fall towards a more adaptive life grounded in "direct, unmediated contact with the real."

Patrones sociolingüísticos de pronunciación en la ciudad de Granada: variación sociofonética del seseo
Authors: Sosiński Marcin
Published: February 2024

Los análisis realizados hasta ahora demuestran que en Granada coexisten tres patrones de las consonantes sibilantes explosivas. Por un lado, se encuentra la variante mayoritaria, distinguidora, seguida por la articulación seseante y por el ceceo. En el siguiente trabajo, a partir de los datos extraídos del corpus PRESEEA-Granada, analizamos el seseo y, por primera vez, contemplamos las variables tanto sociales como lingüísticas y estilísticas, para presentar un modelo estadístico integrador que explique su aparición en las entrevistas. Se realizan análisis bivariantes (con el programa SPSS) y multivariantes (con Rbrul ejecutado en R) que revelan que solo son significativas las variables edad y grado de instrucción, así como el contexto consonántico posterior en la secuencia, priming y la presencia de sibilantes en el ataque silábico. Las demás variables quedan descartadas.

Stanene possesses excellent properties, including an extremely high charge carrier density, massless Dirac fermions, and high thermal conductivity. Moreover, it exhibits band inversion phenomena, being made a candidate for a topological insulator. Topological insulators can generate dissipationless electric currents under certain conditions, showing great application potentials. However, the presence of a Dirac cone in the band structure of stanene at the high-symmetry point K in the Brillouin zone, resulting in a zero band gap, significantly limits its applications in the semiconductor field. This study adopts the method of doping B/N elements in stanene and applying an electric field perpendicular to the stanene to open the band gap at the K point. The effects of doping and the intensity of the applied electric field on the structural and electronic properties of stanene are investigated. The results reveal that both doping B elements and applying a vertical electric field can open the band gap at the K point while preserving the topological properties of stanene. Additionally, there is a positive correlation between the applied vertical electric field intensity and the band gap at the K point. Simultaneously doping B elements and applying a vertical electric field can increase the band gap at the K point, reaching 0.092 eV when the electric field intensity is 0.5 V/Å. After doping N elements, stanene is transformed into an indirect band gap semiconductor with a band gap of 0.183 eV. Applying a vertical electric field cannot change the structure of N-doped stanene, and the intensity of the applied vertical electric field is negatively correlated with the band gap at the K point. When the electric field intensity is 0.5 V/Å, the band gap at the K point decreases to 0.153 eV.

Polaritons, as hybrid excitations of light and matter, are important for miniaturizing the integrated nano-optoelectronic devices due to their capability of manipulating nanolight. Recently, the state-of-the-art nano-imaging technique (e.g. scattering-type scanning near-field optical microscope) has visualized various types of polaritons and revealed the physical mechanism behind them. The nanometer-resolution imaging not only deepens our understanding of fundamentals of polaritons but also promotes the studies of polariton manipulation and applications. In this review paper, we systematically summarize the recent near-field study of polaritons. Rather than other previous reviews focusing on polaritons in two-dimensional materials, our review extends the polaritonic systems to multiple dimensions (3D/2D/1D), at the same time we also collect the latest progress of polaritons in anisotropic systems. Moreover, we show the recent study of polariton manipulation and their corresponding applications, e.g. sub-diffractional imaging, focusing, optical modulator, nanostructure diagnosis and molecular sensing. Our review also look forward to future opportunities of polaritonics and its nanophotonic applications.

Electrical control of magnetism of two-dimensional (2D) antiferromagnetic (AFM) materials combines the advantages of controlling magnetism by purely electrical means, compatibility with semiconductor process, low energy consumption, heterogeneous integration of 2D materials with van der Waals (vdW) interface, and AFM materials with no stray field, resistance to external magnetic field interference, and high intrinsic frequency, and thus becomes a research focus in the field. The carrier concentration control is the main mechanism of electrical control of magnetism, and has been proved to be an effective way to control the magnetic properties of materials. The intralayer-antiferromagnetic materials have net-zero magnetic moments, and it is a challenging task to measure their regulated magnetic properties. Therefore, there is limited research on the electrical control of magnetism of intralayer-antiferromagnetic materials, and their potential mechanisms are not yet clear. Based on the diversity of organic cations, the present work systematically modulates the carrier concentrations of 2D intralayer-antiferromagnetic materials MPX3 (M = Mn, Fe, Ni; X = S, Se) by utilizing organic cations intercalation, and investigates the influence of electron doping on their magnetic properties. Phase transitions between AFM-ferrimagnetic (FIM)/ferromagnetic (FM) depending on carrier concentration changes are observed in MPX3 materials, and the corresponding regulation mechanism is revealed through theoretical calculations. This research provides new insights into the carrier-controlled magnetic phase transition of 2D magnetic materials, and opens up a pathway for studying the correlation between the electronic structure and magnetic properties of 2D magnets, and designing novel spintronic devices as well.

The nuclear pore complex (NPC) regulates the selective transport of large biomolecules through the nuclear envelope. As a model system for nuclear transport, we construct NPC mimics by functionalizing the pore walls of freestanding palladium zero-mode waveguides with the FG-nucleoporin Nsp1. This approach enables the measurement of single-molecule translocations through individual pores using optical detection. We probe the selectivity of Nsp1-coated pores by quantitatively comparing the translocation rates of the nuclear transport receptor Kap95 to the inert probe BSA over a wide range of pore sizes from 35 nm to 160 nm. Pores below 55 ± 5 nm show significant selectivity that gradually decreases for larger pores. This finding is corroborated by coarse-grained molecular dynamics simulations of the Nsp1 mesh within the pore, which suggest that leakage of BSA occurs by diffusion through transient openings within the dynamic mesh. Furthermore, we experimentally observe a modulation of the BSA permeation when varying the concentration of Kap95. The results demonstrate the potential of single-molecule fluorescence measurements on biomimetic NPCs to elucidate the principles of nuclear transport.

The adaptive dynamics of evolving microbial populations takes place on a complex fitness landscape generated by epistatic interactions. The population generically consists of multiple competing strains, a phenomenon known as clonal interference. Microscopic epistasis and clonal interference are central aspects of evolution in microbes, but their combined effects on the functional form of the population’s mean fitness are poorly understood. Here, we develop a computational method that resolves the full microscopic complexity of a simulated evolving population subject to a standard serial dilution protocol. Through extensive numerical experimentation, we find that stronger microscopic epistasis gives rise to fitness trajectories with slower growth independent of the number of competing strains, which we quantify with power-law fits and understand mechanistically via a random walk model that neglects dynamical correlations between genes. We show that increasing the level of clonal interference leads to fitness trajectories with faster growth (in functional form) without microscopic epistasis, but leaves the rate of growth invariant when epistasis is sufficiently strong, indicating that the role of clonal interference depends intimately on the underlying fitness landscape.

Glucocorticoid-induced osteonecrosis of the femoral head (GONFH) is a common refractory joint disease characterized by bone damage and the collapse of femoral head structure. However, the exact pathological mechanisms of GONFH remain unknown. Here, we observed abnormal osteogenesis and adipogenesis associated with decreased β-catenin in the necrotic femoral head of GONFH patients. In vivo and in vitro studies further revealed that glucocorticoid exposure disrupted osteogenic/adipogenic differentiation of bone marrow mesenchymal cells (BMSCs) by inhibiting β-catenin signaling in glucocorticoid-induced GONFH rats. Col2+ lineage largely contributes to BMSCs and was found an osteogenic commitment in the femoral head through 9 mo of lineage trace. Specific deletion of β-catenin gene (Ctnnb1) in Col2+ cells shifted their commitment from osteoblasts to adipocytes, leading to a full spectrum of disease phenotype of GONFH in adult mice. Overall, we uncover that β-catenin inhibition disrupting the homeostasis of osteogenic/adipogenic differentiation contributes to the development of GONFH and identify an ideal genetic-modified mouse model of GONFH.

The respiratory pathogen nontypeable Haemophilus influenzae (NTHi) is the most common cause of exacerbation of chronic obstructive pulmonary disease (COPD), of which an excessive inflammatory response is a hallmark. With the limited success of current medicines there is an urgent need for the development of novel therapeutics that are both safe and effective. In this study, we explored the regulatory potential of pomegranate-derived peptides Pug-1, Pug-2, Pug-3, and Pug-4 on NTHi-induced inflammation. Our results clearly showed that to varying degrees the Pug peptides inhibited NTHi-induced production of IL-1β, a pivotal cytokine in COPD, and showed that these effects were not related to cytotoxicity. Pug-4 peptide exhibited the most potent inhibitory activity. This was demonstrated in all studied cell types including murine (RAW264.7) and human (differentiated THP-1) macrophages as well as human lung epithelial cells (A549). Substantial reduction by Pug-4 of TNF-α, NO and PGE2 in NTHi-infected A549 cells was also observed. In addition, Pug-4 strongly inhibited the expression of nuclear-NF-κB p65 protein and the NF-κB target genes (determined by IL-1β, TNF-α, iNOS and COX-2 mRNA expression) in NTHi-infected A549 cells. Pug-4 suppressed the expression of NLRP3 and pro-IL-1β proteins and inhibited NTHi-mediated cleavage of caspase-1 and mature IL-1β. These results demonstrated that Pug-4 inhibited NTHi-induced inflammation through the NF-κB signaling and NLRP3 inflammasome activation. Our findings herein highlight the significant anti-inflammatory activity of Pug-4, a newly identified peptide from pomegranate, against NTHi-induced inflammation. We therefore strongly suggest the potential of the Pug-4 peptide as an anti-inflammatory medicine candidate for treatment of NTHi-mediated inflammation.
