Published: June 2024

Psoriasis is an immune-mediated disease (a disease with an unclear cause that is characterized byinflammation caused by dysfunction of the immune system) that causes inflammation in thebody.This study included 100 patients and 50 healthy.Aquestionnaire was included sex and age ofpsoriatic patients and healthy subjects, also, psoriatic patients were distributed according to theperiod of infection, family history, severity of psoriasis, and comorbidities of psoriasis. Enzymelinkedimmunosorbent assay (ELISA) used to measure the concentration levels of cytokinesinterleukin-17 (IL-17) and interleukin-4(IL-4) in the serum of the studied samples from both groups.The present results showed no significant differences between psoriatic patients and healthy subjectsaccording to age(P=0.247) andsex (P=0.643), while asignificant differences was observedbetweenpsoriatic patients inperiod of infection (P=0.000), family history (P=0.001), severity ofpsoriasis (P=0.000) and comorbidities of psoriasis (P=0.000), as well, the current results indicated anincrease in the concentration level of IL-17 in psoriatic patients (150.61±55.7 pg/mL) compared withits concentration levels in healthy individuals (96.55±34.pg/mL), with significant difference (P=0.00)at (P≤0.05). Adecrease in the concentration levels of IL-4 in psoriatic patients (136.8±51.9 pg/mL)was observed in this study compared with its concentration levels in healthy individuals(193.84±69.10 pg/mL) with a significant difference between the two groups (P=0.002). It can beconcluded that there is an immunologic imbalance of T cells in psoriasis, which is associated with theupregulation of IL-17 and the downregulation of IL-4 in the circulation. This immune dysregulation,which plays a key role in the disease progression.

Cryptographic Key Exchange Using Blockchain Technology
Authors: Muhsin Naeem Fatima , H. Alibraheem Kadhim
Published: June 2024

Abstract:Cryptographic key management systems (KMS) are an important component of secure communications systems and organisations must protect sensitive information by maintaining confidentiality, integrity, and reliability. In this paper, we create an efficient cryptographic key management application that uses blockchain technology (BC) and fingerprint biometrics to meet this demand. A private network of ten authorised users is created according to the Fingerprint Verification Competition 2000 (FVC2000)database. They create and exchange encrypted keys according to security standards that include confidentiality, authenticity, trust, and limited access to the system. The system requires each authorized user to log in using their email and password, in addition to their fingerprint. The fingerprint is converted to binary if it is grayscale. If the fingerprint already exists in binary format, the system will extract the fingerprint features in matrix form by processing any missing or incorrect information with an emphasis on accurate representation. A 256-bit encrypted key is produced from this matrix after feature retrieval, by converting the feature matrix into a long string which is then fed through the secure hash algorithm 256 (SHA256) function. The app uses blockchain technology to encrypt the key, apply additional encryption, and associate it with a unique hash. The encrypted key is contained within a block. Users then securely exchange this encrypted block. The application strictly accepts authorised users and rejects unauthorised users. The encryption KMS application provides a high level of security and reliability for organizations looking to protect their encryption keys by combining the use of fingerprint biometrics and BC technology.

Authors: M. Essaa Wageeha , M. Taher Al-Asad Widad
Published: June 2024

Abstract It is known that some plants, especially trees, have a chemical antagonistic effect on plants growing under them by not growing their seeds or not reaching the flowering stage. Therefore, this study showed this effect, as the effect of some concentrations of Calotropis procera plant extract was studied on some indicators of Catharanthus roseus (L.) G.Don growth. and its chemical characteristics, as it was noticed that the plant decreases with growth and the formation of lateral branches whenever the concentration increases compared to the control samples that were irrigated with water. Also, the number of flower buds decreases with increasing concentrations of C. procera plant extract , the concentrations used for the extract affected the height of C. vinca plant , while the leaf area also decreased with increasing concentration. The number of active chemical compounds in C. vinca plant was also affected by C. procera extract compared with the control sample, as it was noted that the highest number of compounds was 32 in the samples that were not treated with the extract, while the highest concentration of the extract was 2.5 ppm, so the number of compounds was 25.The concentrations of compounds in the C. vinca plant differed from one concentration to another compared to the control samples, some of which decreased, some increased, some disappeared, and some concentrations appeared, new compounds that were not present in the control plant, and most of these compounds have an important medical, therapeutic or industrial effect.
Image Segmentation and Grouping Using Graph Method (SLIC Algorithm)
Authors: N. manea Intisar
Published: June 2024

AbstractThis paper provides a comprehensive review of graph-based image segmentation methods. Various graph-based algorithms and their applications are explored, including multiple surface segmentation, saliency detection, and colour-texture segmentation. This work introduced a superpixel algorithm and Simple Linear Iterative Clustering (SLIC) algorithm to segment an image using a graph representation. The results show that graph-based methods like SLIC can effectively model images as graphs and optimize segmentation to group visually coherent pixels while respecting intensity variations and spatial proximity between pixels. The key concepts, importance of image segmentation, and challenges are also discussed. While the demonstration provides basic validation of graph-based principles, opportunities remain for improvement such as incorporating edge features and neural networks to address oversegmentation issues. Overall, the review and experimental results highlight the effectiveness of graph-based segmentation methods in computer vision domains.

Authors: Alaa khadim Mohammed1  , Salam Jasim Majeed
Published: June 2024

This paper centers on an eco-epidemiological predator-prey model that accounts for hunting cooperation among predators and prey shelter and fear in afflicted prey. The objective is to investigate the effects of parameter factors on the model's bifurcation behavior. Theoretical part of this study demonstrate that a transcritical bifurcation can result from infection rate and refuge rate. Furthermore, fear rate can cause a Hopf-bifurcation to arise close to the positive equilibrium point. The presence of local bifurcations close to the non-trivial equilibrium points is verified by numerical analysis, which also guarantees the veracity of the theoretical results.

Ibero Gutiérrez: el valor de la Palabra, o la impronta heideggeriana de una época
Authors:   Universidad Nacional del Sur, Ferreira Peñaflor Sebastián
Published: June 2024

El presente trabajo se propone aportar a una genealogía filosófica del pensamiento de Ibero Gutiérrez. Los estudios dedicados a quien es considerado por algunos el mayor exponente de la generación del año 68 en el Uruguay, han puesto de relieve exclusivamente elementos de carácter estético y político. Por contraposición a la recepción predominante en la lectura del joven escritor, asesinado a los 22 años por un grupo parapolicial, se pone de relieve la influencia de Martin Heidegger en un creador emblemático de la izquierda histórica del Uruguay. Se desglosa la lectura que hace Gutiérrez de Heidegger, no sólo presente en la temática de su obra, sino también a través de distintas notas al margen que se encuentran en la biblioteca personal del joven creador, acervo que hoy forma parte del Museo de la Memoria de Montevideo. La plena inscripción de esa influencia heideggeriana contribuye asimismo, a restituir los marcos de referencia filosóficos de la Facultad de Humanidades y Ciencias, de la que Gutiérrez fue estudiante. La conclusión del trabajo se dirige a subrayar la integración del pensamiento filosófico europeo en el Uruguay de los años sesenta e inicios de los setenta y la impronta que inscribe en la propia genealogía intelectual de sectores políticos insurgentes.

Actualidad en la Escuela de Frankfurt: crítica al tecnoceno
Authors:   Tecnológico de Monterrey CEM, Gómez Vargas Christian Guillermo
Published: June 2024

El artículo examina la posible aproximación entre la Dialéctica de la Ilustración y el fenómeno del tecnoceno, desde la perspectiva crítica de la Escuela de Frankfurt. El artículo se centra en la exploración de la forma en que la razón instrumental está implicada desde los orígenes del pensamiento moderno, basada en un modelo de expropiación de la naturaleza y dominio del mundo que, bajo la impronta de un paradigma económico fundado en el capitalismo, este se cristaliza en la noción de crecimiento ilimitado. La razón deviene únicamente un instrumento, correlato de los mecanismos de generación de valor económicos; tal como había concluido la Dialéctica de la Ilustración. El estudio busca comprender las implicaciones de estas dinámicas en la articulación de la subjetividad, asimismo, en la concreción de instituciones, Estado, dispositivos de sentido y de generación de valor económico, y de qué manera estos confabulan a la crisis ecológica global. A través de un enfoque interdisciplinario que combina la filosofía crítica de la Escuela de Frankfurt, con análisis contemporáneos sobre tecnología, sociedad y el medio ambiente, se revisarán textos clave de autores como Horkheimer y Adorno, junto con investigaciones recientes sobre la denominada época del tecnoceno, concepto que no representa más que una especificación que dota de mayor precisión al de Antropoceno. Se pretende ofrecer una reflexión actualizada sobre la relevancia de la crítica frankfurtiana en el siglo XXI, destacando su potencial para promover sociedades más justas, democráticas y sostenibles en un mundo caracterizado por la omnipresencia tecnológica y desafíos ambientales.
Influencia de la filosofía del romanticismo en el arte contemporáneo
Authors:   Universidad de Guadalajara, González Ramírez Luna
Published: June 2024

El texto aborda la influencia de la filosofía estética del romanticismo en el arte contemporáneo. Múltiples obras de arte contemporáneo son criticadas fuertemente por ser conceptuales, feas o egoístas. Estas categorías estéticas no surgen de la nada, ya que fueron trabajadas durante el romanticismo. En esta época se puede apreciar en la filosofía un pensamiento radical al respecto de la obra de arte que motivó nuevas formas de producción y expandió el criterio mediante el cual una pieza podía ser considerada una obra de arte. La influencia filosófica de Hegel, Rosenkranz y Schopenhauer sigue siendo vigente en el siglo XXI, por lo que es fundamental evidenciar los aspectos en los que sus filosofías coinciden con obras de arte contemporáneas.

Authors: Legasari Leni , Wati Ambar , Yani Dwi Fitri
Published: June 2024

Areca catechu L. has been widely used as a traditional medicine in medicinal practices in various countries around the world. Areca nut contains secondary metabolite compounds such as alkaloids, flavonoids, triterpenoids, steroids, and tannins so it has great potential to be developed as a medicine. The use of anti-inflammatory drugs from natural ingredients is widely developed because synthetic non-steroidal anti-inflammatory drugs cause side effects to the body such as nausea, diarrhea, headaches, and stomach ulcers. This study aims to determine the content of secondary metabolites and determine the anti-inflammatory activity of ethanol extracts of young and old areca nut seeds. Old areca nut seeds used are areca nut fruits that have an orange color while young areca nut seeds are areca nut fruits that have a green color. The anti-inflammatory activity test method was carried out using the protein denaturation inhibition method at 5, 10, 15, and 20 ppm extract concentrations. The results of this study indicate that young and old areca nut seeds positively contain alkaloids, flavonoids, tannins, and saponins and negatively contain steroids. The results of anti-inflammatory activity testing show that ethanol extracts of young and old areca nut seeds have the potential as anti-inflammatory because they have a percentage value of protein denaturation inhibition greater than 20%. A comparison of anti-inflammatory activity between areca nut seeds can be seen from the IC50 value of ethanol extract. The IC50 results show that young areca seeds have an IC50 value of 7.42 ppm which is higher than the old areca seeds of 11.52 ppm

Cancer is a disease caused by unnatural cell growth in the body. It has become a disease with a high mortality rate in the world. Several therapies have been developed for cancer treatment, one of which is the exploration of the bioactivity of compounds contained in potentially medicinal plants. One of the potential medicinal plants that grows in Central Kalimantan province is L. leucocephala. In this study, the potential of L. leucocephala leaf extract was explored through phytochemical tests and molecular docking approaches. Based on the phytochemical test, it was found that L. leucocephala leaf extract contains flavonoids, terpenoids, and steroids. Based on the test results, a literature study was conducted on the flavonoids and terpenoids content in L. leucocepala leaf extract and molecular docking studies were conducted. Seven dominant compounds of L. leucocephala consisting of flavonoids and terpenoids were tested for their potential as inhibitors of receptor tyrosine kinase. The molecular docking results showed that flavonoid ligands (1-6) had more negative binding affinity values compared to the drug sunitinib, a common drug for cancer therapy, while terpenoid ligand (7) had less favorable binding energy.

This study aims to analyze the link between Perceived Volatility Reduction (PVR), Risk Perception, Stablecoin Usage Frequency, Market Confidence, and Stablecoin Adoption (SA). The primary goal is to determine if and to what degree these variables impact stablecoin adoption. We created a questionnaire to gather information from 198 Malaysians. To analyze the research model and test the hypotheses, the Structural Equation Modeling-Partial Least Squares (SEM-PLS) method was utilized. According to the findings, there is a strong and positive association between Perceived Volatility Reduction (PVR) and Stablecoin Adoption (SA). Market players are more likely to adopt stablecoins if they perceive them as useful instruments for mitigating the severe price volatility inherent in traditional cryptocurrencies. This finding emphasizes the importance of risk perception and market stability in driving market behavior. Trust in stablecoin systems, transparency, and regulatory, compliance influenced PVR and SA. The study's findings underscore the significance of perceived volatility reduction (PVR) in driving stablecoin adoption (SA), highlighting the importance of risk perception and market stability. Trust in stablecoin systems, transparency, and regulatory compliance emerge as crucial factors influencing PVR and SA. These insights offer valuable guidance for investors navigating the cryptocurrency market, governments managing stablecoin supply, and scholars studying trust dynamics in the cryptocurrency ecosystem.

Published: June 2024

Global bond market attention is starting to witness very interesting developments in the development of Sukuk. However, the academic literature on the determinants of the development of the Sukuk market is still new and very limited. Using the Vector Autoregression (VAR)/Vector Error Correction Model (VECM) method, this study examines how the financial risk component influences the development of the Indonesian sovereign Sukuk market. Data was collected from Bank Indonesia and Indonesia’s Directorate General of Financing and Risk Management on the External Debt Statistics database for ten years from 2013Q1-2023Q1. The results of this study indicate that the foreign Debt Service Ratio (DSR) and Exchange Rate (EXC) significantly affect the development of the sovereign Sukuk Market. The foreign DSR has a negative effect, while the EXC positively affects the development of the sovereign Sukuk market. Meanwhile, the ratio of foreign debt to Gross Domestic Product (GDP) has an insignificant effect on the development of the sovereign Sukuk Market. The findings advocate policymakers in Indonesia on the importance of strengthening financial stability and regulating the issuance of Sukuk in accordance with the associated financial risks to develop the Sukuk market properly.

Introdução: O excesso de peso está associado ao desequilíbrio energético provocado pela alta ingestão calórica e pela baixa atividade física. O jogo interativo é uma proposta de intervenção, sobretudo entre o público jovem, na promoção da atividade física. Objetivo: Testar a hipotese do impacto da atividade física com uso de videogame ativo sobre o perfil glicêmico de adolescentes com excesso de peso. Métodos: Estudo de intervenção controlado realizado no segundo semestre de 2018. A amostra foi composta por 70 adolescentes com excesso de peso, distribuídos nos grupos controle e experimental, com idade entre 10 e 16 anos, matriculados entre o 5º e o 9º ano do ensino fundamental II de escolas públicas do município de Campina Grande/ PB. Foram estudadas variáveis sociodemográficas, de estilo de vida, estado nutricional e bioquímicas. A resistência insulínica foi determinada através do índice TyG: (triglicerídeos-glicemia: ([triglicerídeos de jejum (mg/dL) x glicemia de jejum (mg/dL))]/2. Para realização da intervenção foi utilizada a plataforma XBOX 360, com o acessório Kinect (Microsoft®). Foi aplicado um formulário geral, aferido o peso; a estatura e a circunferência abdominal e realizada coleta sanguínea. Para aumentar o engajamento dos adolescentes na atividade de intervenção adotou-se uma estratégia de gamificação. Os dados foram analisados no SPSS 22.0 e adotou-se nível de significância de 5% nos testes estatísticos. Para testar o efeito da intervenção sobre o perfil glicêmico foi aplicado o teste do qui-quadrado. Para avaliar o efeito da intervenção sobre a adiposidade abdominal foi aplicado o teste t- pareado. Resultados: A intervenção melhorou o IMC e reduziu a adiposidade abdominal dos adolescentes, mas não causou alterações significativas sobre o perfil glicêmico. Conclusão: O uso do videogame ativo para aumentar a atividade física em adolescentes com excesso de peso em ambiente escolar é uma ferramenta eficaz para melhorar o estado nutricional de adolescentes. Intervenções com maior tempo de duração necessitam ser avaliadas para verificar os possíveis efeitos no perfil glicêmico. Está é uma intervenção viável, de baixo custo e aproveita recursos tecnológicos em sintonia com interesse da população alvo.
