Published: August 2024

Blockchain and the Internet of Things (IoT) are becoming pivotal in the IT industry, finding applications in sectors like supply chain, logistics, and the automotive industry. IoT devices often have limited processing and storage capabilities, leading to the centralization of user medical data in third-party repositories or cloud environments. Blockchain offers decentralized processing and storage for IoT data, making it an attractive option for creating decentralized IoT-enabled e-healthcare systems. This chapter begins with an overview of blockchain technology, followed by a discussion of prominent consensus algorithms within the context of e-health. It also evaluates various blockchain platforms for their suitability in IoT-based e-healthcare systems. Several case studies are presented methodically to demonstrate the utilization of IoT and blockchain core features in enhancing healthcare services and ecosystems.

Authors: Abad-Segura Emilio , Castillo-Díaz Francisco José , Batlles-delaFuente Ana , Belmonte-Ureña Luis J.
Published: August 2024

The purpose of accounting ethics is to ensure honest and transparent financial information for sustainable decision making. Recent accounting scandals have resulted in regulatory changes to limit the influence of lobbies on regulators and the accounting profession. This study aims to examine the link between accounting ethics and sustainable decision making, based on an analysis of 343 articles. The findings show that research on accounting ethics has increased steadily, but its connection with sustainable decision making remains limited. While various topics have been studied, there are gaps in the research, including a lack of critical analysis of accounting frauds that pose risks to the accounting profession and, consequently, sustainable decisions. The chapter suggests future research directions, including interdisciplinary approaches focusing on earnings transparency, the value relevance of accounting, ethical blockchain technology, and epistemic responsibility. It also questions the opacity of research on accounting ethics and its implications for sustainable decision making.
Experimental Determination of Tensile Stress Concentration Factors of 3D-Printed PLA Polymers: Fillet Radius, Hole Diameter, and Infill Density
Authors: Zabihollah Abolghassem , Bardowell Stephen , Does Bryan , Vuddandam Rajesh
Published: August 2024

3D-printing technology is being used as a regular approach in prototyping and the production of machine components. However, despite their metallic counterparts, there are many issues including infill pattern, density, and stress concentration coefficient in 3D printing that are not well-defined. The infill density plays a significant role in the printing time and mechanical properties of the printed objects. On the other hand, like metallic materials, changing geometry, such as fillet radius and hole alters the strength of the printed elements. In this work, experimental works have been conducted to determine the effect of infill density on the tensile strength of 3D printed elements. Furthermore, various standard specimens for tensile testing have been prepared to investigate the effects of fillet radius and in-plane hole diameters on the tensile strength of PLA 3D-printed elements with different infill density. Using the experimental results, the tensile stress concentration coefficients as a function of fillet radius, hole diameters, and infill density have been determined. The results of the present work can be used as a guideline for analytical design and manufacturing 3D printing objects.

Published: August 2024

Resistance to ultraviolet light is an essential factor that coating materials must possess, especially for outdoor applications. In this study, the effect of ultraviolet light exposure on the properties of polyurethane coating with the addition of chlorinated rubber was systematically examined. The ultraviolet light exposure was performed using an ultraviolet weathering tester for 500 hours. The samples were investigated through mechanical testing, complemented by scanning electron microscope and Fourier transform infrared spectroscopy. The increase in the tensile strength and elongation at break of the polyurethane coating with the addition of chlorinated rubber was observed and compared to the pristine sample. In the beginning of the ultraviolet exposure, the tensile strength increased 486% and 114% for pristine polyurethane and polyurethane/chlorinated rubber until of 80 hours ultraviolet exposure, indicating repolymerization during the ultraviolet exposure. It was confirmed by the Fourier transform infrared spectra which showed an increase in peak intensity at wave number of 1712 cm־ˡ which indicated C=O bond in the polyurethane. The surface morphology showed micro-cracking caused by ultraviolet exposure. Finally, it was concluded that the addition of chlorinated rubber improved the resistance to ultraviolet light.
Oxidizing Effect of Corn Starch by Oxidizing with Hydrogen Peroxide Purpose Obtaining its Basis Adhesive Materials
Authors: Sharipov Muzafar Samandarovich , Tillayeva Dildora Murodilloyevna , Panoyev Nodir Shavkatovich
Published: August 2024

Currently, native starch as a binder and sizing component is used extremely rarely due to its inherent disadvantages. It has been replaced everywhere with modified starches of various kinds. Studies have shown that polyelectrolyte flocculants can be created on the basis of starch if ionizable groups are introduced into the macromolecules of amylose and amylopectin. At the same time, it was found that the treatment of starch with oxidizing agents (of various natures and activities) can significantly improve the functional properties of native starch when gluing, used for surface sizing, and as a binder for corrugated cardboard. In this work, we also obtained oxidized starch in order to create an adhesive binder on its basis, and only local raw materials were used. It is shown that this method makes it possible to regulate the number of functional groups (oxidizing effect, or OE) in oxidized starch and its paste viscosity within a wide range. This is achieved by changing the molar ratio of the catalyst and oxidizer. During the oxidation process, it is possible to vary the concentration ratios of the oxidizer, catalyst, and conditions. Using FeSO4 as a catalyzer, the oxidized starch pastes show a less pronounced pseudoplasticity and are characterized by reduced viscosity. The analysis showed that during the oxidation of corn starch with hydrogen peroxide, changes in the supramolecular structure of starch are insignificant: a certain repeated decrease in the level of crystallinity takes place, which leads to a decrease in the gelatinization temperature and also the viscosity of starch pastes.

Published: August 2024

A 29-year-old man presented to the emergency department with haemoptysis and thoracic pain. His vital signs and blood tests were normal, except for increased C-reactive protein levels. Fibrolaryngoscopy and esophagogastroduodenoscopy results were negative. Computed Tomography of the chest revealed abundant pneumomediastinum, air dissection along the peribronchovascular sheaths of the left lower lobe and a vegetating lesion completely occluding the distal extremity of the left main bronchus. After complete bronchoscopic excision of the lesion, histological examination revealed a carcinoid tumour not otherwise specified. After hospital discharge, 18F-fluorodeoxyglucose and 68Ga-DOTANOC positron emission tomographies ruled out distant metastases. A sleeve resection of approximately 20 mm of the distal extremity of the left main bronchus and a circumferential anastomosis between the left main bronchus and ipsilateral lobar bronchi were performed. Several bronchoscopic follow-ups did not show anastomotic dehiscence or tumour relapse.
Psychological interventions in the Italian national health system: appropriateness and accountability
Authors: Ridolfi Alessandro
Published: August 2024

In the field of clinical governance, the search for progressive high-quality health interventions is accompanied by the different health values they assume for the different stakeholders involved. With increasing frequency, the value of clinical psychology and psychotherapy interventions in the public service is also supported by their ability to be appropriate and measurable in terms of their effectiveness. As such, their expected future is one of systematic inclusion within increasingly defined and specific care pathways. The challenge that this evolution poses is complex from an epistemologicalmethodological point of view because it must include the various perspectives from which one looks at the nature of these interventions. Clinical appropriateness, as a meta-level variable, and accountability go beyond the simplistic/generic cost-benefit assessment of services and are proposed as a necessary conceptual framework for an adequate determination of outcomes.

Published: August 2024

Background: Activation of the mitogen-activated protein kinase (MAPK) pathway induces uncontrolled cell proliferation in response to inflammatory stimuli. Adriamycin (ADR)-induced nephropathy (ADRN) in rats triggers MAPK activation and pro-inflammatory mechanisms by increasing cytokine secretion, similar to chronic kidney disease (CKD). Activation of the vitamin D receptor (VDR) plays a crucial role in suppressing the expression of inflammatory markers in the kidney and may contribute to reducing cellular proliferation. This study evaluated the effect of pre-treatment with paricalcitol on ADRN in renal inflammation mechanisms. Methods: Male Sprague-Dawley rats were implanted with an osmotic minipump containing activated vitamin D (paricalcitol, Zemplar, 6 ng/day) or vehicle (NaCl 0.9%). Two days after implantation, ADR (Fauldoxo, 3.5 mg/kg) or vehicle (NaCl 0.9%) was injected. The rats were divided into four experimental groups: control, n = 6; paricalcitol, n = 6; ADR, n = 7 and, ADR + paricalcitol, n = 7. Results: VDR activation was demonstrated by increased CYP24A1 in renal tissue. Paricalcitol prevented macrophage infiltration in the glomeruli, cortex, and outer medulla, prevented secretion of tumor necrosis factor-α, and interleukin-1β, increased arginase I and decreased arginase II tissue expressions, effects associated with attenuation of MAPK pathways, increased zonula occludens-1, and reduced cell proliferation associated with proliferating cell nuclear antigen expression. Paricalcitol treatment decreased the stromal cell-derived factor 1α/chemokine C-X-C receptor type 4/β-catenin pathway. Conclusions: Paricalcitol plays a renoprotective role by modulating renal inflammation and cell proliferation. These results highlight potential targets for treating CKD.
Local dimer dynamics in higher dimensions
Authors: Hartarsky Ivailo , Lichev Lyuben , Toninelli Fabio Lucio
Published: August 2024

We consider local dynamics of the dimer model (perfect matchings) on hypercubic boxes

[n]^{d}

. These consist of successively switching the dimers along alternating cycles of prescribed (small) lengths. We study the connectivity properties of the dimer configuration space equipped with these transitions. Answering a question of Freire, Klivans, Milet, and Saldanha, we show that in three dimensions any configuration admits an alternating cycle of length at most 6. We further establish that any configuration on

[n]^{d}

features order

n^{d-2}

alternating cycles of length at most

4d-2

. We also prove that the dynamics of dimer configurations on the unit hypercube of dimension

d

is ergodic when switching alternating cycles of length at most

4d-4

. Finally, in the planar but non-bipartite case, we show that parallelogram-shaped boxes in the triangular lattice are ergodic for switching alternating cycles of lengths 4 and 6 only, thus improving a result of Kenyon and Rémila, which also uses 8-cycles. None of our proofs make reference to height functions.
Morse subsets of injective spaces are strongly contracting
Authors: Sisto Alessandro , Zalloum Abdul
Published: August 2024

We show that a quasi-geodesic in an injective metric space is Morse if and only if it is strongly contracting. Since mapping class groups and, more generally, hierarchically hyperbolic groups act properly and coboundedly on injective metric spaces, we deduce various consequences relating, for example, to growth tightness and genericity of pseudo-Anosovs/Morse elements. Moreover, we show that injective metric spaces have the Morse local-to-global property and that a non-virtually cyclic group acting properly and coboundedly on an injective metric space is acylindrically hyperbolic if and only if contains a Morse ray. We also show that strongly contracting geodesics of a space stay strongly contracting in the injective hull of that space.

Pretreatment can alleviate programmed cell death in mesenchymal stem cells
Authors: Wan Xin-Xing , Hu Xi-Min , Zhang Qi , Xiong Kun
Published: August 2024

In this editorial, we delved into the article titled “Cellular preconditioning and mesenchymal stem cell ferroptosis.” This groundbreaking study underscores a pivotal discovery: Ferroptosis, a type of programmed cell death, drastically reduces the viability of donor mesenchymal stem cells (MSCs) after engraftment, thereby undermining the therapeutic value of cell-based therapies. Furthermore, the article proposes that by manipulating ferroptosis mechanisms through preconditioning, we can potentially enhance the survival rate and functionality of MSCs, ultimately amplifying their therapeutic potential. Given the crucial role ferroptosis plays in shaping the therapeutic outcomes of MSCs, we deem it imperative to further investigate the intricate interplay between programmed cell death and the therapeutic effectiveness of MSCs.

Published: August 2024

In regenerative medicine, the isolation of mesenchymal stromal cells (MSCs) from the adipose tissue’s stromal vascular fraction (SVF) is a critical area of study. Our review meticulously examines the isolation process of MSCs, starting with the extraction of adipose tissue. The choice of liposuction technique, anatomical site, and immediate processing are essential to maintain cell functionality. We delve into the intricacies of enzymatic digestion, emphasizing the fine-tuning of enzyme concentrations to maximize cell yield while preventing harm. The review then outlines the filtration and centrifugation techniques necessary for isolating a purified SVF, alongside cell viability assessments like flow cytometry, which are vital for confirming the efficacy of the isolated MSCs. We discuss the advantages and drawbacks of using autologous vs allogeneic SVF sources, touching upon immunocompatibility and logistical considerations, as well as the variability inherent in donor-derived cells. Anesthesia choices, the selection between hypodermic needles vs liposuction cannulas, and the role of adipose tissue lysers in achieving cellular dissociation are evaluated for their impact on SVF isolation. Centrifugation protocols are also analyzed for their part in ensuring the integrity of the SVF. The necessity for standardized MSC isolation protocols is highlighted, promoting reproducibility and successful clinical application. We encourage ongoing research to deepen the understanding of MSC biology and therapeutic action, aiming to further the field of regenerative medicine. The review concludes with a call for rigorous research, interdisciplinary collaboration, and strict adherence to ethical and regulatory standards to safeguard patient safety and optimize treatment outcomes with MSCs.

Evaluation of Ozonated Water as a Potential Intervention to Reduce Salmonella and Indicator Organisms on Raw Chicken Wing Sections
Authors: Cano Carmen , Sullivan Gary A. , Chaves Byron D.
Published: August 2024

The objective of this study was to evaluate the effective-ness of ozonated water to reduce Salmonella and aerobic plate counts (APCs) on raw chicken wing sections. Sam-ples were inoculated with a cocktail of five poultry-borne Salmonella strains (mean 6.3 ± 0.3 log10 CFU/ml rinsate). The chicken wing sections (51.3 ± 12.4 g) were treated with ozonated water at three concentrations (2.5, 5.0, and 10.0 ppm) and three exposure times (15, 30, and 45 s) by either immersion or direct application (directly from a hose). Tap water was used as control, and the experi-ments were performed in triplicate with three wings per treatment. Salmonella reductions with ozonated water ranged from 0.3 ± 0.1 to 0.7 ± 0.1 log10 CFU/ml rinsate. APC reductions with ozonated water ranged from 0.3 ± 0.1 to 1.8 ± 0.7 log10 CFU/ml rinsate. Reductions were numerically higher, although not significantly, with ozonat-ed water than with tap water. Ozone concentration had a significant effect (P = 0.003) on Salmonella reductions in immersion treatment. Although Salmonella reductions on chicken wing sections were considered marginal, future work should focus on evaluating longer exposure times and ozone concentrations on the microbiological quality of raw chicken parts, possibly as part of a multihurdle antimicro-bial approach.

Published: August 2024

The aim of this study was to investigate current practices in the food industry regarding the development and implementation of food safety management systems, with a focus on employee health policies. Specifically, this study assessed written employee health policies and practices that retail food establishments used to mitigate the risk of foodborne illnesses. Surveys were distributed, and 14% (76/538) of the surveys were returned by senior food safety leaders, representing 336,268 restaurant, grocery, and convenience store outlets. The majority of participants represented larger franchises or chains. Results showed most participants (98.4%) reported having written employee health policies, with most policies based on the U.S. Food and Drug Administration’s Model Food Code and Annex. Most participants (98.3%) agreed that their employee health policy stipulated exclusions and restrictions for food employees based on their health and activities as they relate to diseases transmitted through food; however, fewer (87.7%) policies had provisions for removing such exclusions and restrictions. The survey also revealed the use of novel approaches to promote handwashing and the frequency with which conditional employees are made aware of reporting requirements. Taken as a whole, the survey highlights opportunities to improve employee health policies and increase awareness of reporting requirements for employees in the retail food industry.
Sodium-dependent glucose transporter 2 inhibitors effects on myocardial function in patients with type 2 diabetes and asymptomatic heart failure
Authors: Grubić Rotkvić Petra , Rotkvić Luka , Đuzel Čokljat Ana , Cigrovski Berković Maja
Published: August 2024

BACKGROUND

Sodium-dependent glucose transporter 2 inhibitors (SGLT2i) have shown efficacy in reducing heart failure (HF) burden in a very heterogeneous groups of patients, raising doubts about some contemporary assumptions of their mechanism of action. We previously published a prospective observational study that evaluated mechanisms of action of SGLT2i in patients with type 2 diabetes who were in HF stages A and B on dual hypoglycemic therapy. Two groups of patients were included in the study: the ones receiving SGLT2i as an add-on agent to metformin and the others on dipeptidyl peptidase-4 inhibitors as an add-on to metformin due to suboptimal glycemic control.

AIM

To evaluate the outcomes regarding natriuretic peptide, oxidative stress, inflammation, blood pressure, heart rate, cardiac function, and body weight.

METHODS

The study outcomes were examined by dividing each treatment arm into two subgroups according to baseline parameters of global longitudinal strain (GLS), N-terminal pro-brain natriuretic peptide, myeloperoxidase (MPO), high-sensitivity C-reactive protein (hsCRP), and systolic and diastolic blood pressure. To evaluate the possible predictors of observed changes in the SGLT2i arm during follow-up, a rise in stroke volume index, body mass index (BMI) decrease, and lack of heart rate increase, linear regression analysis was performed.

RESULTS

There was a greater reduction of MPO, hsCRP, GLS, and blood pressure in the groups with higher baseline values of mentioned parameters irrespective of the therapeutic arm after 6 months of follow-up. Significant independent predictors of heart rate decrease were a reduction in early mitral inflow velocity to early diastolic mitral annular velocity at the interventricular septal annulus ratio and BMI, while the predictor of stroke volume index increase was SGLT2i therapy itself.

CONCLUSION

SGLT2i affect body composition, reduce cardiac load, improve diastolic/systolic function, and attenuate the sympathetic response. Glycemic control contributes to the improvement of heart function, blood pressure control, oxidative stress, and reduction in inflammation.
Nomogram predicting the cardiovascular disease mortality for older patients with colorectal cancer: A real-world population-based study
Authors: Tan Jia-Yu , Shen Shuo-Hao
Published: August 2024

BACKGROUND

Cardio-oncology has received increasing attention especially among older patients with colorectal cancer (CRC). Cardiovascular disease (CVD)-specific mortality is the second-most frequent cause of death. The risk factors for CVD-specific mortality among older patients with CRC are still poorly understood.

AIM

To identify the prognostic factors and construct a nomogram-based model to predict the CVD-specific mortality among older patients with CRC.

METHODS

The data on older patients diagnosed with CRC were retrieved from The Surveillance, Epidemiology, and End Results database from 2004 to 2015. The prognostic factors and a nomogram-based model predicting the CVD-specific mortality were assessed using least absolute shrinkage and selection operator and Cox regression.

RESULTS

A total of 141251 eligible patients with CRC were enrolled, of which 41459 patients died of CRC and 12651 patients died of CVD. The age at diagnosis, sex, marital status, year of diagnosis, surgery, and chemotherapy were independent prognostic factors associated with CVD-specific mortality among older patients with CRC. We used these variables to develop a model to predict CVD-specific mortality. The calibration curves for CVD-specific mortality probabilities showed that the model was in good agreement with actual observations. The C-index value of the model in the training cohort and testing cohort for predicting CVD-specific mortality was 0.728 and 0.734, respectively.

CONCLUSION

The proposed nomogram-based model for CVD-specific mortality can be used for accurate prognostic prediction among older patients with CRC. This model is a potentially useful tool for clinicians to identify high-risk patients and develop personalized treatment plans.

The wavelet transform and its multiple versions in many aspects of the spectral analysis, the wavelet transform, likewise its relation with other transforms and special functions, needs a special treatment due to that in last years the developments in quantum electronics and recognition of signals in the frequency domain, likewise exploration profuse on new research in advanced materials like special semiconductors or fine devices in medicine, where the research is more detailed and majorly more specific in different applications. Likewise we have the wavelet transform of special function where each one can establish of very useful way the creation and design of special signal filters used in the modern industry in electronics, data processing analysis or even in the configuration of the advanced electronic equipment. Also the interphase between reception-emission devices with sensorial parts of the human body, in biomedical engineering. A version is interesting like the quantum wavelet transform which is very useful in the spectral study of traces of particles, for example studied from atomic accelerator. Finally are given general results to the discrete study of signal, which is analyzed to the wavelet transform and its spectra.

This study aims to understand the relationship between corporate social responsibility and the financial performance of companies in the healthcare sector in Vietnam. The sample size of the study is 242, including data collected from 22 listed companies in the healthcare industry in Vietnam, during the period from 2012 to 2022. By using Stata software research methods and tests, research results show that corporate governance, human rights, and community have a significant impact on the financial performance of healthcare businesses in Vietnam, while employee relations and environment have no impact on financial performance. From there, this study makes several recommendations that healthcare companies should have reasonable regulations to adjust the gender balance on the board of directors and develop a code of ethics on human rights associated with CSR activities, thereby implementing training programs to improve the quality of human resources, and needing to allocate investment costs in production technologies appropriately to optimize operating performance and profits of the business.

This article delves into the intricacies of managerial innovation within Moroccan public organizations, focusing on the challenges and enablers that shape its adoption. By drawing upon Imam Ali's Letter 53, a seminal work in governance, the study underscores the necessity of a gradual and culturally attuned approach to introducing new managerial practices. The findings reveal that, despite its critical role in enhancing organizational performance, managerial innovation is often underutilized, hindered by resistance to change and the apprehension of disrupting established norms. Letter 53 provides timeless principles that address these challenges, advocating for the careful and respectful integration of innovations while upholding local cultural and ethical values. The study further emphasizes that managerial innovations which are congruent with cultural traditions and benefit all stakeholders are more likely to flourish. Moreover, it highlights the pivotal role of transparent communication and employee involvement in the change process as essential factors in mitigating resistance and fostering acceptance of new practices.

La espondiloartritis axial (EspAax) es una enfermedad crónica inflamatoria que incluye a la espondiloartritis radiográfica (EspAax-r) (anteriormente conocida como espondilitis anquilosante [EA]) y a la espondiloartritis axial no radiográfica (EspAax-nr). Los pacientes con EspAax-nr pueden tener compromiso inflamatorio espinal detectado por resonancia magnética (RM) pero, a diferencia de los pacientes con EA, no tienen evidencia de daño estructural radiográfico suficiente para cumplir los criterios de New York modificados. Ambos fenotipos generan un importante impacto en la calidad de vida, el estado global de salud y la productividad laboral si no son tratados en forma oportuna y adecuada.
Si bien existen guías de tratamiento para EspAax, como las de la American College of Rheumatology/Spondyloarthritis Research and Treatment Nework (ACR/SPARTAN), de la Panamerican League of Associations of Rheumatology (PANLAR) y del Assessment in SpondyloArthritis International Society/European Alliance of Associations for Rheumatology (ASAS/EULAR), las diferencias clínicas y los diversos contextos socioeconómicos justifican el desarrollo de guías nacionales.
En los últimos años se logró un gran avance tanto en el conocimiento de la fisiopatología como en el desarrollo farmacológico para el tratamiento de la EspAax, lo que nos permite tomar decisiones terapéuticas más dirigidas y personalizadas. Hasta el momento, no se han desarrollado guías de recomendaciones para el tratamiento de la EspAax en Argentina. Existe evidencia que muestra que uno de los factores más importantes para la adecuada implementación de las guías en países de bajos ingresos es el esfuerzo para adaptarlas desde la perspectiva de los proveedores de atención médica por lo que consideramos de suma importancia el desarrollo de las mismas localmente.
Por lo tanto, el objetivo del Grupo de Estudio de la Sociedad Argentina de Reumatología (SAR) de EspAax y Artritis Reactiva (GESAR EspAax-ARe) fue confeccionar recomendaciones para el manejo terapéutico de pacientes adultos con EspAax en nuestra población.
Explorando os memes

O artigo aborda a transformação no ensino da Língua Portuguesa, iniciada na década de 1980 com a ascensão da linguística textual, que deslocou o foco do estudo gramatical do texto para uma abordagem centrada na linguagem como forma de interação social. Destaca-se a Base Nacional Comum Curricular (BNCC, 2017) por refletir essa mudança, ao incorporar os gêneros textuais digitais no contexto do ensino da língua materna, reconhecendo o texto como expressão viva da linguagem. O estudo discute sobre o ensino da leitura de gêneros textuais digitais para alunos do 8º e 9º anos do Ensino Fundamental, alinhado com as diretrizes da BNCC. Inspirado na teoria de Bakhtin (2003), debruçando-se sobre os aspectos denominados conteúdo temático, composição estrutural e estilo dos gêneros digitais, especificamente, do meme. O objetivo deste trabalho é possibilitar aos professores o desenvolvimento de habilidades de leitura crítica em seus alunos, visando a uma comunicação eficaz no ambiente digital, a fim de promover uma compreensão mais contextualizada e atualizada do ensino da Língua Portuguesa.

Published: August 2024

Este artigo é um recorte advindo de pesquisa realizada no âmbito do mestrado PROFLETRAS/UFPB e apresenta uma proposta de leitura didática problematizadora do racismo no Brasil. As atividades foram desenvolvidas em roda de conversa, mediada por tirinhas que trazem à tona estereótipos raciais como uma forma de desconstruir o racismo sobretudo em espaço escolar. Para tanto, baseamo-nos nas discussões a partir de Orlandi (2020) para versar sobre a leitura de abordagem discursiva; em Almeida (2021) para tratar do racismo; e em Brasil (2018), para abordar acerca das políticas públicas educacionais. Nossa metodologia parte da pesquisa qualitativa, sendo os dados gerados por meio de questionários e analisados pelos estudos discursivos materialistas. Como resultado, percebemos gestos de leitura que compreenderam os ditos e os não-ditos possíveis às condições de produção das tiras trabalhadas.
