Digital twin modeling: A comparison of current approaches
Authors: Sommer Lutz
Published: March 2024

Background The implementation of digital twins is of growing importance due to increasing interest. Various procedural models are used or are currently being developed in theory and practice. However, there is no generally accepted model. The aim of the present study is to record and analyze existing models and from the perspective of deriving development trends. Method In the first step, a systematic literature search is carried out; in the second step, the results are subjected to a comparative analysis. Results The study provides an overview of common process models for implementing Digital Twins. Fifteen approaches were selected for a detailed analysis. 1/3 are hybrid process models (i.e. a combination of several models), sequential and evolutionary models still dominate, and the phase length is between 5 – 10 phases. In other words, the majority of the existing process models analysed surprisingly follow a more sequential approach. Discussion Process models with a sequential character - with and without accompanying project management - dominate, but hybrid approaches are increasing in importance: (a) on the one hand as an integrated project management component, i.e. a combination of agile and classic project management, since these meet the digital twin requirements in terms of hardware (= rather classic approach), software (= more agile approach) and data management; (b) on the other hand, the merging or mutual supplementation of existing data science approaches - such as data mining with CRISP-DM - with the above project management approaches is to be expected.
Diriliş: Resurrection theme in the populist regime of ‘New Turkey’
Authors: Aydin Hazal
Published: March 2024

Populism has become the pillar of contemporary right-wing politics, and it has a large discursive toolkit, varying in different geopolitical contexts but always drawing its references from existing narratives, myths, affects, and cosmologies of a given public. The success of populist regimes lies particularly in their ability to harness existing imaginaries and turn them into political currency. Turkey’s Justice and Development Party (AKP) is no exception to this trend through its constant cultivation of antagonistic themes and manufacture of new hostilities. To get a better grasp of the ways in which this is accomplished, this report focuses on one of the most appealing, popular, and political themes in Turkish-Islamist politics: Diriliş (Resurrection). One can come across this theme in national politics, foreign policy, popular media, or the Islamist intellectual realm. Starting out as a Turkish Sunni Islamist philosophy in the Islamist intellectual realm, the diriliş theme proliferated over the years, subsequently with the rise of political Islam, and became a building block of Turkish-Islamist populist discourse in Turkey. With a close focus on various Islamist journals in İslamcı Dergiler Projesi (Islamic Journals Project) database and media, popular culture, and politics, this report charts the trajectory of the diriliş theme from the 1960s until today. I show its popularization process, its politicization throughout decades, and its gendered foundation. Diriliş theme appears and disappears at significant political moments in Turkey, and it successfully appeals to Turkish-Islamist groups while converting feelings of oppression to power and domination. Its loaded history makes diriliş a very powerful instrument for AKP’s populism.
Better treatment response in people with obsessive-compulsive disorder is associated with more use of a planning-focused coping style
Authors: Kirkham Elizabeth , Cao Yintao , Król Martyna
Published: March 2024

Background Obsessive-compulsive disorder (OCD) is a common and highly disabling mental health condition. Although effective treatments such as cognitive behavioural therapy are available, a substantial minority of patients do not respond to treatment, and those who do often experience relapse. There is an urgent need to understand more about the psychological factors involved in response to OCD treatment. Prior literature suggests that poorer treatment response may be related to higher levels of early life stress and experiential avoidance, while better treatment response may be related to positive coping styles (planning; active coping). Methods Individuals with OCD (n = 202) took part in an online survey in which they reported what OCD treatment they had received, and how their OCD symptoms at the time of the survey compared to their OCD symptoms before they had received any treatment. They also completed measures of OCD severity, early life stress, experiential avoidance, planning and active coping. Depression and anxiety were measured as control variables. Results It was found that more severe OCD symptoms were associated with higher levels of early life stress and more use of experiential avoidance, but were unrelated to planning or active coping. On the other hand, a better self-reported response to OCD treatment was associated with more use of the planning style of coping, but was not associated with early life stress, experiential avoidance or active coping. Conclusions The present study highlights planning-focused coping as a possible modifiable factor in maximising treatment response in people with OCD. Given that sustained recovery from OCD is relatively rare, research that focuses on how to maximise the benefit of existing treatments could have a significant impact on individuals living with the condition.
Chemicals regulation and non-animal methods: displacing the gold standard
Authors: Carusi Annamaria
Published: March 2024

Regulating industrial chemicals in foodstuffs and consumer products is a major aspect of protecting populations against health risks. Non-animal testing methods are an essential part of the radical change to the framework for toxicity testing that is long overdue in global economies. This paper discusses reasons why the drive to reduce animal testing for chemical safety testing is so difficult to achieve, as perceived by those who are closely involved in chemicals regulations in different capacities. Progress is slow, despite the fact that the ethico-legal conditions for a move away from animal testing are largely in place, and despite scientific arguments for a radical change in the paradigm of toxicity testing, away from reliance on animal studies. I present empirical data drawn from two studies in a European Commission context promoting non-animal methods. The aim of the paper is modest. It is to foreground the voices of those who deal with the science and regulation of chemicals on a day-to-day basis, rather than to offer a theoretical framework for what I heard from them. I offer a synthesis of the main challenges faced by non-animal alternatives, as these are perceived by people in different stakeholder groups dealing with chemicals regulation. I show where there are pockets of agreement between different stakeholders, and where the main disagreements lie. In particular there is dispute and disagreement over what counts as validation of these alternative tests, and by implication of the traditional ‘gold standard’ of animal testing. Finally, I suggest that the shift to non-animal methods in chemicals regulation demonstrates the need for the concept of validation to be broadened from a purely techno-scientific definition, and be more explictly understood as a demand for trust and acceptance, with more attention given to the complex social, institutional and economic settings in which it operates.

Toward Platform-Economy Continuity: Do Descriptive Norms and Perceived Product Attributes Matter to Youths who Use Ride-Hailing Apps?
Authors:   Department of Management, Faculty of Economics and Business, Universitas Hayam Wuruk Perbanas, Fauzi Abu Amar
Published: March 2024

Abstract. This study investigates how descriptive norms and perceived product attributes (utilitarian and hedonic benefits) influence the intention of young consumers to continue to adopt ride-hailing apps. We developed a conceptual model drawing upon the socio-technical theory by involving 333 Indonesian users of ride-hailing apps and estimating the model using the statistical tool of PLS-SEM-based software. The findings showed that social aspects (descriptive norms) and technical aspects (utilitarian and hedonic benefits) significantly influence young consumers to adopt ride-hailing apps. Intriguingly, a positive perception of the apps’ benefits is instrumental for encouraging young consumers to continue to adopt ride-hailing apps when descriptive norms appear, when peers in their social circle widely adopt similar apps. This study highlights the unique behavior of young consumers in adopting ride-hailing apps by accentuating the role of descriptive norms and perceived product attributes from the perspective of socio-technical theory. This study provides practical recommendations for digital platform providers, particularly TNCs (Transportation Network Companies), which offer ride-hailing services to address the young consumer segment with a community-based marketing approach to maintain their continued adoption.

Trust in E-government Practices: A Platform Perspective of a Postal Service Organisation
Authors:   Kwame Nkrumah University of Science and Technology, Kumasi, Ghana, Boateng Kofi Agyenim , Coffie Rosemary Boateng , Darko Peter
Published: March 2024

Abstract. E-government continues to gather research momentum from academics of diverse theoretical and practical orientations to signify the enduring significance of the concept, especially from the standpoint of digital service delivery in much of the developing world. A platformisation perspective driven by digital service delivery is teased out to make a case for this study. Dwelling on the fundamental assumptions of a positivistic research philosophy with the UTAUT epistemological model as the guiding frame to solicit responses of students in an online environment, the study employs quantitative techniques to analyse eight hypothetical scenarios. Findings suggest trust in e-government, Internet trust, social influence and performance expectancy are some of the strong predictors of intention to use e-government services. The study discusses the revelation that citizens are particularly influenced by peer pressure in their intention to use public digital services. Theoretical implications and empirical lessons of the factors that should be of significant consideration to system designers and policy makers in e-government practice have been accounted for. Future research can take the direction of qualitative efforts to bring out the underlying rationale and tensions connected with digital service acceptance in e-government practice. Keywords: Digital Service, E-government, Emerging Economies, Platformisation, Trust
The Effect Of Internship Quality Toward Self-Perceived Employability Through The Mediation of Career-Entry Worries For Final Year Student at Universitas Indonesia
Authors:   Faculty of Administrative Science, Universitas Indonesia, Sakapurnama Eko , Hasan Siti Amalia ,   KDDI Corporation Indonesia
Published: March 2024

Abstract. Competition in the world of work is getting tougher over time which triggers a sense of worry and lack of confidence to enter the world of work for young people who do not have work experience, particularly fresh graduates. It is theorized in this paper that, by participating in internship, students can increase their self-perceived employability, thereby reducing their career-entry worries. Specifically, the purpose of this study was to analyze the effect of internship quality on self-perceived employability through the mediation of reduced career-entry worries for final year students at Universitas Indonesia. This study administered online surveys (with 209 respondents) and in-depth interviews (with 3 source persons). The results show that internship quality has a positive influence on self-perceived employability and reduced career-entry worries. Further, self-perceived employability also positively affects reduced career-entry worries and reduced career-entry worries mediate the effect between internship quality and self -perceived employability. This study recommends that universities in Indonesia can implement a compulsory internship program for its students equally.
Measuring Performance of Digital Projects: Case of Swiss Medium-sized Enterprises
Authors:   Institute for Information Systems, School of Business, University of Applied Sciences and Arts Northwestern Switzerland, Klinkert Thierry André , Meyer Mona A. , Nainggolan Yunieta Anita ,   School of Business and Management Institut Teknologi Bandung
Published: March 2024

Abstract. The research objective is to understand the challenges of digitalisation of Swiss medium-sized enterprises and their satisfaction with current measurement methods, and to develop a measurement model to evaluate the performance of their digital projects. The research methodology involved a comprehensive literature review, followed by interviews with experts from 15 medium sized companies. The analysis revealed that Swiss medium sized enterprises not only lack the appropriate tools to measure their digital projects’ performance but are also facing challenges caused by the lack of financial resources and time to implement digital projects; and the difficulty of finding the right people to execute digital projects. The results from the research include a measurement model for digital projects. This model supports managers in making effective decisions regarding their digital projects, allocating resources more effectively, and enhancing overall organizational performance. The research outcomes are not necessarily generalizable to other enterprises (other size, other nations). However, they show that in the context of digital projects, Swiss medium-sized companies need a measurement model to evaluate the performance and success since such technologies/projects are associated with financial costs. For future research, the developed model should be tested with different firms in an operational handling where effective past or future projects would be measured. This could further explore the applicability of the model to different sized enterprises or those in other nations.

Abstract. The non-fungible token (NFT) is a unique token used to represent digital assets such as art, music, videos, and other collections. NFT has gained significant attention from the business and industry sectors in recent years. This study reports an increase in the number of active NFT users from 77,000 to 222,000 in early 2021. Investment in NFT has advantages and disadvantages, and one of the challenges faced by investors is that they may not have enough knowledge about investing risks and may find it difficult to recognize and evaluate potential dangers. To address this problem, this study proposes a system that provides information on NFT collection sales rankings and volume sales forecasts. The simple additive weighting (SAW) method is used to determine the NFT collection rankings, and exponential smoothing is used to forecast sales volume. The Particle Swarm Optimization (PSO) method is applied to optimize the parameter alpha of the Exponential Smoothing method. With an accuracy rate of 80.38%, the combination of using the Single Exponential Smoothing method with PSO optimization can provide good predictions for future NFT sales. The proposed system aims to provide investors with accurate information to make informed decisions when investing in NFT. Keywords: Forecasting system, pso, ranking system, saw, single exponential smoothing

Artificial intelligence has emerged as one of the biggest disruptive technologies of the new era and will continue to evolve in the future. AI takes an important role in marketing processes, and the use of AI in marketing is massively increasing and can be easily found. Beauty industry is one of the industries where most companies develop their AI technology to attract customers. This innovation utilizes AI technology in providing solutions to problems related to makeup and/or skincare as experienced by the customers. This study aims to analyze the relationship between technology readiness, technology acceptance model and subjective norm as potential factors in encouraging the customer to use AI technology in the beauty industry. The data was collected using a google form questionnaire. The sampling technique for this research was purposive random sampling. A total of 155 responses were collated and only 127 responses are qualified with the criteria ‘ever using AI Technology in the beauty industry’. The results showed that while perceived usefulness had no significant impact on the intention to utilize AI technology, perceived comfort and subjective standards did. Additionally, the perceived advantages and ease of use are affected differently by each element of technology readiness.

Retracting a ball in $\ell_1$ onto its simple spherical cap
Authors: Intrakul Jumpot , Iampiboonvatana Smith Yokpaisan
Published: March 2024

In this article, a notion and classification of spherical caps in the sequence space $\ell_1$ are introduced, and the least Lipschitz constant of Lipschitz retractions from the unit ball onto a spherical cap is defined.
In addition, an approximation of this value for the specific spherical cap, the simple spherical cap, is calculated. This approximation reveals a rough relation between these values, denoted by $\kappa(\alpha)$, and the answer of the optimal retraction problem for the space $\ell_1$, denoted by $k_0(\ell_1)$.
To be precise, there exists $-1< \mu< 0$ such that $k_0(\ell_1)\leq\kappa(\alpha)\leq2+k_0(\ell_1)$ whenever $-1< \alpha< \mu$; here $\alpha$ is the level of spherical cap.

Introduction: Periosteal chondromas are rare, slow-growing, benign cartilaginous tumors arising from the cortical surface of the bone, beneath the periosteal membrane. Typically affect young males, the most common site being the proximal humerus. There have been no reported cases of periosteal chondroma of the talus in the literature. Case Report: A 9-year-old Indian boy presented with a 1.5-year history of atraumatic right ankle pain and swelling, exacerbated by walking, with limited dorsiflexion. Physical examination revealed a firm, painless swelling on the anterior ankle’s talar region, accompanied by equinus deformity. Radiography displayed osseous masses on the anterior talus. Magnetic resonance imaging indicated well-defined osseous growths originating from the talus’s anterior aspect, likely osteochondromas, with adjacent osseous fragments in the tibiotalar joint, suggestive of loose bodies, supporting a clinical diagnosis of synovial chondromatosis. Surgical excision revealed whitish, hard, irregular tissue, confirmed as periosteal chondroma on histopathology. After 6 months, the patient is pain-free with unrestricted movement and no clinical or radiological signs of recurrence. Conclusion: This case report presents a unique instance of previously unreported talus periosteal chondroma, adding novelty to medical literature. It details the diagnostic challenges and its intricacies. It provides a comprehensive overview of clinical presentation, imaging and histopathological findings, differentials and provisional diagnosis, surgical approach, and post-operative outcomes. The successful surgical management, along with the specific details of the surgical procedure (anteromedial approach, excision, and curettage), adds practical insights for orthopedic surgeons and contributes to the existing knowledge on treatment strategies for talus periosteal chondroma. This report will serve as an excellent educational resource. Keywords: Periosteal chondroma, talus, pediatric patient, surgical management, rare case report.

Introduction: The femoral neck system (FNS) represents an emerging fixation system designed for the management of femoral neck fractures. This innovative system combines the mechanical benefits of compression and anti-rotation properties in internal fixation. Biomechanical studies have demonstrated the superior axial and rotational stability of the FNS implant when compared to traditional cannulated screws and dynamic hip screw. Despite these promising mechanical advantages, there is currently a limited body of literature addressing the factors contributing to FNS failure. A thorough assessment of the safety and outcomes associated with this novel implant is essential. Case Report: In this context, we present three cases wherein FNS failure occurred, aiming to elucidate the potential causes behind these failures, and had to undergo either an implant removal or bipolar hemiarthroplasty. Conclusion: While considering the femoral neck system as the implant of choice, we should consider the age, injury to surgery time, and the location of the fracture line . However, we cannot conclusively ascertain whether age contributes independently to the risk of failure. Keywords: Femoral neck system, neck femur fracture, limitations, subcapital fracture.

Introduction: Synovial chondromatosis (SC) is a relatively rare benign disorder characterized by developing many nodules composed of cartilage within the synovial cavities of joints. It impacts several joints, with the knee joint being the most often affected. Extra-articular involvement, such as bursae or tendon sheaths, is rare. Furthermore, the coexistence of intra- and extra-articular SC is an infrequent condition. Hence, we present a rare case of SC with intra- and extra-articular involvement. Case Presentation: The patient, a 38-year-old woman, reported experiencing progressive right knee discomfort for 2 months. In addition, a growing mass was observed on the medial aspect of the right knee that was noticeable for the past 2 months. MRI examination revealed the presence of both intra-articular and extra-articular lesions. A two-step surgical procedure, including arthroscopy synovectomy involving the debridement of the lesions and removal of the extra-articular mass through an open incision, was performed. Histopathological analysis confirmed SC. At the 1-year follow-up, the patient reported complete relief of discomfort in the right knee. Conclusion: The coexistence of extra-articular and intra-articular SC is an exceedingly rare condition. Surgical removal of the loose bodies and a synovectomy performed as thoroughly as possible constitute the mainstay of treatment in managing SC.

Introduction: Humeral shaft and distal humerus fractures have several different treatment options, including plate fixation and intramedullary nailing. Each has its own benefits, but typically, they are not used in conjunction. While nail-plate combinations (NPCs) have become more common in the lower extremity, literature on their use in upper extremity fractures remains scarce. Case Report: A 74-year-old right-hand dominant male presented after a fall with a closed left transverse midshaft humerus fracture and an associated supracondylar distal humerus fracture with intercondylar extension through a medial column. Due to the segmental nature of his injury, medial column plating was used in conjunction with a retrograde intramedullary nail to obtain anatomic reduction and fixation of the articular injury while stabilizing the midshaft humerus fracture with minimal soft tissue disruption. The patient was recommended non-weight bearing through his left arm for 6 weeks, at which point he returned to weight bearing as tolerated. He was allowed to range his left elbow after 2 weeks. His left elbow range of motion at the 4-month follow-up was 20-135 degrees, and he reported minimal pain. Conclusion: The retrograde NPC should be considered in segmental humeral fractures involving the distal articular surface and midshaft humerus fractures as it limits violation of the soft tissue while avoiding iatrogenic disruption of the articular surface at the shoulder or elbow. Keywords: Trauma, complex fracture, humerus fracture, nail-plate combination.

Introduction: Ramp lesions, often associated with anterior cruciate ligament (ACL) injuries, exhibit a varied incidence rate of 9–42%, increasing with delayed ACL reconstruction. These lesions, resulting from abnormal tibial movements and semimembranosus muscle contraction, are challenging to diagnose due to their hidden nature in standard magnetic resonance imaging and arthroscopy procedures. Case Report: This report examines the case of a ramp lesion in the context of a multi-ligament injured knee of a 34-year-old male. The patient had a complete ACL, medial collateral ligament, and avulsion of the posterior cruciate ligament with a type 1 ramp lesion. These findings were confirmed by arthroscopy and were treated with arthroscopic reconstruction of the ligament and all inside repair of the ramp lesion. We report the pertinent imaging findings relevant to the ramp lesions. Conclusion: Ramp lesions present a significant diagnostic and treatment challenge in orthopedic practice. Enhanced imaging techniques and a deeper understanding of their pathophysiology are crucial for an accurate diagnosis. Keywords: Ramp, hidden lesion, magnetic resonance imaging, arthroscopy.
Counter-Imperial Horizons in Antony and Cleopatra

Published: March 2024

Abstract: This article contests the equation of early modern understandings of world and empire by recuperating a notion of world that eludes our ability to know and possess it. It considers how Antony and Cleopatra employs the concept of the horizon to illuminate the virtues of what we cannot know—allowing us to embrace the unknown as a source of potential. Through a presencing of what might have been, the play recovers an understanding of world that exists beyond the scope of imperial authority and its historical record. Even as it closes in on an imperial history already determined, Antony and Cleopatra animates a lost horizon of possibilities and reveals the potential for multiple worlds contained in the presence of now.
Global Shakespeares: Journeys and Destinations
Authors: Singh Jyotsna G.
Published: March 2024

Abstract: This piece examines Global Shakespeares as a worldwide phenomenon today, evident in the proliferating Shakespearean adaptations and appropriations. It begins with the premise that scholars and practitioners no longer approach the contextual coordinates of individual plays only within traditional English sources and Western performance histories; instead, their interest lies in global, intertextual, and cross-cultural mediations of Shakespeare in a dazzling array of languages, aesthetic traditions, and geopolitical fault lines across boundaries of nation, race, gender, and class hierarchies. Through this process the Global Shakespeares project enables us to read global cultural difference on the stage and screen as well as in texts with contextual depth, while enabling us to draw on local non-Western cultures to reinterpret Shakespeare.
No Othello: Disidentification in Season of Migration to the North
Authors: Lee Xavier
Published: March 2024

Abstract: In this piece, I consider how Tayeb Salih's novel Season of Migration to the North uses the image of Othello from Shakespeare's eponymous play to critique colonial desire and self-making. Appropriating José Esteban Muñoz's theory of disidentification and Homi Bhabha's concept of mimicry, I argue that Season of Migration to the North models in its depictions of Mustafa Sa'eed's sexual carnage and iconographic self-making a disidentificatory critique of Othello 's sense of racial tragedy.

A mid-infrared laser-based sensor is designed and demonstrated for trace detection of benzene, toluene, ethylbenzene, and xylene isomers at ambient conditions. The sensor is based on a distributed feedback inter-band cascade laser emitting near 3.29 µm and an off-axis cavity-enhanced absorption spectroscopy configuration with an optical gain of 2800. Wavelength tuning and a deep neural network (DNN) model were employed to enable simultaneous and selective BTEX measurements. The sensor performance was demonstrated by measuring BTEX mole fractions in various mixtures. At an integration time of 10 s, minimum detection limits of 11.4, 9.7, 9.1, 10, 15.6, and 12.9 ppb were achieved for benzene, toluene, ethylbenzene, m-xylene, o-xylene, and p-xylene, respectively. The sensor can be used to detect tiny BTEX leaks in petrochemical facilities and to monitor air quality in residential and industrial areas for workplace pollution.

The laser output characteristics of Nd:Lu2O3 crystals were investigated in detail to obtain a dual-wavelength all-solid-state laser. Using 806 nm LD end-face pumped Nd:Lu2O3 crystals with lengths of 6 mm, a 1076 & 1080 nm laser outputs with a maximum output power of 3.73 W were obtained, with a slope efficiency of 30.4%, an optical-to-optical conversion efficiency of 28.5%, and a power stability of 0.41% for 4 h of continuous measurement. Furthermore, by suppressing the higher-order modes, a high beam quality laser output with beam quality factors of 2.092 and 1.589 in the x and y directions, respectively, and a maximum output power of 1.27 W were obtained. In addition, it was experimentally verified that both wavelengths of the output laser were elliptically polarized.

Published: March 2024

This paper presents the design and numerical investigation of a graphene-based switchable terahertz (THz) metasurface for ultrawideband absorption and multiband cross polarization conversion. The device’s operational mode can be altered to absorption or reflection by using the electrostatic capabilities exhibited by graphene. The numerical calculations yield results indicating that in absorption mode, it maintains a bandwidth ratio of 152% within the frequency range of 1.04–7.74 THz. In polarization conversion mode, the design demonstrates the ability to convert linearly polarized and circularly polarized waves to their respective cross-polarization states within the frequency ranges of 1.8–2.5 THz, 3.5–4.1 THz, and 5.6 THz. Moreover, calculated results indicate that linear-to-circular conversion can be realized at 2.64, 3.45, and 5.4 THz frequencies. In addition, the absorption and polarization conversion ratio parameters were analyzed using the multiple reflection theory, which demonstrated significant agreement with the simulation results. The designed metasurface exhibits significant potential in the field of terahertz devices, including stealth technology, smart switches, and other related applications.
Coherent Control of Relativistic Electron Dynamics in Plasma

Published: March 2024

Femtosecond laser pulses, amplified to ultrahigh intensities, can drive electrons in solids to relativistic energies via collective motion, paving the way for miniaturized particle accelerators and powerful extreme-ultraviolet light sources. However, precisely controlling the space-time properties of these ultra-fast electrons on sub-femtosecond timescales remains a formidable challenge due to the complex nature of interaction at such extreme fields. Here, we present a novel approach to coherently control the local fields on sub-femtosecond timescales at the interface between vacuum and spatially structured plasma generated from a periodic array of dielectric nanopillars. We experimentally demonstrate and theoretically explain that such control of fields enables enhanced acceleration and steering of relativistic electrons in a desired direction. Furthermore, our simulations predict the coherent formation of sub-femtosecond electron bunches from the nanopillars. Our research brings nanophotonics to the realm of strong-field plasma physics and represents the enabling
advancement for in-situ control of high-energy particles, paving the way for novel applications in plasma technology.

Objective

To determine the effective dose and therapeutic potential of maropitant using through expression of mediators of oxidative stress, inflammatory and of the unfolded protein response (UPR) (bio) markers on spinal cord using a model of neuropathic pain induced through chronic constriction injury (CCI) in rats.

Study design

Randomized, blinded, prospective experimental study.

Animals

98 male Wistar rats.

Methods

Rats were anesthetized with sevoflurane and after CCI, they were randomly assigned to the following groups that received: vehicle, 3, 6, 15, 30 e 50 mg/kg/24q of maropitant. The effect on inflammatory mediators (IL10, TNFα), oxidative stress (GPx, CAT, SOD), microglial (IBA-1) and neuronal (NeuN, TACR1) markers was evaluated though immunohistochemistry and expression levels of markers of hypoxia (HIF1α, Nrf2), antioxidant enzymes (Catalse, Sod1 and GPx1), and endoplasmic reticulum stress mediators (GRP78, CHOP and PERK) through qRT-PCR.

Results

Intraperitoneal injection (IP) of maropitant inhibited nociception with ID50 values of 4,1 mg/kg (5,85–19,36) in a neuropathic pain model through CCI. A dose of 30 mg/kg/24q was significantly effective in reducing mechanical allodynia 1 to 4h after treatment with nociception inhibition (145,83%). A reduction in the expression of hypoxia factors (HIF1α, Nrf2) was observed, along with an increase in antioxidant activity (CAT, SOD and GPX). Additionally, there was a reduction in inflammatory markes (IL10, TNFα), microglial (IBA-1), and neuronal markers (NeuN, TACR1).

Conclusion and clinical relevance

These findings demonstrate that the determined dose, administered daily for seven days, had an antinociceptive effect, as well as anti-inflammatory and antioxidant activity.
