Network Pharmacological Analysis Identifies the Curcumin Analog CCA-1.1 Targeting Mitosis Regulatory Process in HER2-Positive Breast Cancer
Authors: Novitasari Dhania , Jenie Riris Istighfari , Kato Jun-ya , Meiyanto Edy
Published: April 2023

Recent studies present that the CCA-1.1 (a curcumin derivative) impedes the proliferation of breast cancer cells (luminal, HER2-overexpressed, and TNBC cells). Currently, we analyze the possible target of action of CCA-1.1, particularly in breast cancer cells with HER2 amplification using bioinformatics analysis. The differentially expressed genes (DEGs) of HER2-positive breast cancer were retrieved from TCGA-BRCA data (via UALCAN). We used three web-based tools (Swiss Target Prediction, BindingDB, and TargetNet) to predict the potential target of CCA-1.1 using the SMILE-similarity feature. The functional annotation and network enrichment were processed in WebGestalt. The alteration of selected genes was observed in CBioPortal. The protein-protein interaction (PPI) network was constructed in STRING, then ranked based on the degree score using Cytohubba feature in Cytoscape. The survival analysis from the hub-gene was collected in GEPIA2 with selection only for HER2-positive breast cancer cases. The correlation between the hub genes and tumor-infiltrating immune markers was determined using TIMER web tools. The pathway network analysis highlighted the cell cycle regulation in mitosis as affected signaling amid the putative CCA-1.1 targets. We denoted eight potential genes that could be responsible for inhibiting mitosis regulation upon CCA-1.1 treatment, including AURKA, AURKB, PLK1, TPX2, KIF11, MELK, CDK1, and CHEK1. Several of the potential markers (AURKB, AURKA, CDK1, and CHEK1) revealed to be correlated with the immune cells’ infiltration markers. CCA-1.1 might regulate mitosis to induce cell cycle arrest and lead to cell death. The predicted targets of CCA-1.11 gave insight into the potency of CCA-1.1 to be with immunotherapy. Further validation of the data presented in the study is essentially needed to develop CCA-1.1 for breast cancer.

Published: April 2023

In over 30 years, the forms of public legal education activities have become increasingly rich. However, with the technology refresh, the traditional public legal education model characterized by one-way communication has gradually become out of touch, which can not adapt to the return of the people’s subjectivity and meet the personalized needs of different groups of people. As an important part of advancing the Rule of Law in China, public legal education should be timely innovated with the help of new technology. By combining the knowledge graph technology in the era of artificial intelligence with the work of public legal education, this paper studies how to use the knowledge graph technology to build public legal education network platform, introduce customized legal education content, and establish a sound mechanism for intelligent public legal education work, so that users can complete the important transformation from the object of legal education to the subject of law learning. This will enrich the theoretical research results of public legal education.

Determinación anticipada de la vida útil del proyecto minero como esencial para la fijación de los límites temporales de la servidumbre legal minera y la cuantificación de las indemnizaciones a que tendrá derecho el propietario del predio sirviente
Authors: Guggiana Varela María Karina
Published: April 2023

The mining easement is essentially temporary.  It is delimited by virtue of the use made of the dominant property, so it is necessary that at the time of its constitution the useful life of the mining operation projected by the mining concessionary be determined in advance, thus allowing the identification of the temporary extension of the lien that is sought to be imposed on the servant property, as well as adequately quantify the damages that the owner of the latter will have the right to receive by way of compensation.
At present, serious adverse legal effects are generated to the interests of the owner of the servant property, since there are no legal norms that allow establishing the time limit at the time of constituting this type of easement, the transitory nature that is characteristic of them is distorted, mutating to an ineffable indeterminate extension of them, which also results in the non-specificity of the damages that must be compensated to the owner of the property.

Published: April 2023

Abstract: The modern technology has increased the standard of living for the humans. With the advancement of technology, the level of acceptance of people of all ages towards electronic gadgets is increasing steadily. Electronic gadgets such as barcode scanner smart card reader and RFID scanner are gaining more and more usage in various kinds of industries. So with the help of these we came up with this innovative project is of an automated billing system which can be placed at a side where the customer is flexible to use at any time. This automated payment system consists of a RFID reader which is controlled by Arduino. So, whenever the customer places the tag it is detected by the RFID module and is displayed on LCD along with the price of the item. As the customer goes on adding items, all items are detected by the module and therefore the price will increase accordingly. In case if customer changes his/her mind and doesn’t want any item added to the bill he/she can remove it and the price added will be deducted automatically. At the end of the entire process the total amount to be paid will be displayed. We can also pay the bill using the mobile application in the app itself. The mobile application is operated by the Wi-Fi module used in the hardware implementation. After the payment the bill will generate successfully. Hence this technique is an appropriate method to be used in places like hotels so this will help in reducing manpower and helps in making a better billing experience for customers.

Published: April 2023

Abstract: The development of advanced computer vision techniques has made it possible to perform real-time face and object detection for video surveillance applications. Video surveillance is an essential tool for monitoring public areas, buildings, and other locations for security and safety purposes. However, analyzing the vast amount of data generated by video surveillance systems can be challenging. Real-time face detection and object detection systems provide an effective solution to this problem, enabling the identification and tracking of people and objects of interest. In recent years, there has been a growing interest in incorporating age prediction and gender prediction into video surveillance systems. The ability to predict the age and gender of individuals can provide valuable insights to enhance the effectiveness of video surveillance applications. For example, age and gender prediction can be used to detect and prevent potential crimes. This research paper presents a study of a real-time face and object detection system with age and gender prediction for video surveillance applications. The proposed system utilizes deep learning and convolutional neural network techniques to achieve high accuracy in face and object detection, as well as age and gender prediction. The experimental results demonstrate the effectiveness of the proposed system in accurately detecting and tracking faces and objects while predicting their age and gender in real time. The proposed system has potential applications in various fields

Published: April 2023

Excessive noise exposure during the manufacturing process is a widespread issue. This research aimed to analyze noise exposure in the kernel recovery station in the manufacturing process of palm oil. We conduct some measurements and calculations for noise exposure analysis to get the Equivalent Noise Level (Leq) value during the daytime for each measurement point. The noise measurement was conducted on four machines, including a depericarper and polishing drum machine, ripple mill machine, silo dryer machine, and clay bath machine. In addition, this research showed noise contour mapping to define the noise distribution.  The results of this research are that only the clay bath machine had Ls below the threshold. The clay bath machine workstation has good noise levels. The Depericarper, Polishing Drum, Ripple Mill, and Silo Dryer Machine must be quieter. Thus, this research used the Hierarchy of Control Approach to reduce and control hazardous noise exposure.

Se determinó el efecto de la adición de xoconostle en la fermentación ruminal in vitro de rastrojo de maíz con objeto de reducir la emisión de metano. Estudios previos han demostrado que el xoconostle contiene compuestos bioactivos con actividad antimicrobiana potencial que mejoran la fermentación ruminal. Se adicionaron el 0.0%, 2.0%, 4.0% y 6.0% de xoconostle. Se determinó la composición química de los sustratos, compuestos fenólicos, capacidad antioxidante, desaparición in vitro de la materia seca (DIVMS), la producción de ácidos grasos volátiles (AGV) y las variables de cinética de producción de gas. El volumen de metano se midió utilizando la técnica de captura de bióxido de carbono en solución de hidróxido de sodio. Con la adición del xoconostle se incrementó significativamente (P<0.05) el contenido de proteína, extracto etéreo, fenoles totales y actividad antioxidante. La DIVMS también se incrementó con la adición del xoconostle. Respecto a la producción de ácido propiónico, ésta se incrementó significativamente (P<0.05) con el 6.0 % de xoconostle. Los parámetros cinéticos obtenidos mediante el mejor ajuste de los datos experimentales mostraron una mayor tasa de digestión y menor producción de metano con la adición del 4.0 y 6.0 % de xoconostle. El uso de xoconostle como aditivo en dietas para rumiantes disminuye la producción de metano in vitro por lo que puede ser una alternativa para mitigar el incremento del efecto invernadero y beneficiar el cultivo de un fruto comercialmente no muy apreciado.

This work determined the acaricidal effect of 18 Mexican plants against Rhipicephalus microplus. The results of the larvicidal assay revealed that 5 methanolic extracts produced high activity (86-100 % mortality), 3 extracts exhibited relatively high activity (71-85 % mortality), 2 extracts displayed moderate activity (56-70 % mortality), 2 extracts presented low activity (31-55 % mortality) and 6 extracts showed non-significant acaricidal activity (0-30 % mortality). Extracts inducing >56 % mortality were subsequently assayed against engorged ticks of R. microplus by adult immersion test at a concentration of 5.0% w/v. In general terms, the results on larvae and adult ticks indicated that the methanolic extracts of Annona globiflora, Annona scleroderma, Litchi chinensis and Azadirachta indica showed the greatest activities. The crude extract of A. indica was subjected to chromatographic purification, which has led to the isolation of 3-O-butyl-(-)-epigallocatechin (1), 3-O-butyl-(-)-epicatechin (2), (-)-epigallocatechin (3), (+)-gallocatechin (4), (-)-epicatechin (5), β-sitosterol (6), stigmasterol (7), stigmasterol glucoside (8), triolein (9), azadirachtin A (10), and the octadecanoic acid-tetrahydrofuran-3,4-vinyl ester (11). The isolated compounds' chemical structures were identified by the interpretation of NMR and HRESI-MS spectroscopic data. The isolated compounds were assayed against engorged ticks of R. microplus at a concentration of 6 mM. Based on the results obtained, it was concluded that 3-O-butyl-(-)-epigallocatechin (1), 3-O-butyl-(-)-epicatechin (2), azadirachtin A (10), and octadecanoic acid-tetrahydrofuran-3,4-vinyl ester (11) show the highest effectiveness.

Perception of impoliteness in refusal and response to it by native speakers of English and Persian
Authors: Tajeddin Zia , Rassaei Moqadam Hojjat
Published: April 2023

Impoliteness entails the employment of strategies oriented toward attacking face and bringing about social disruption. Although research on impoliteness has received great attention in the past two decades, how impolite utterances are perceived and what the recipients of impoliteness do in return has remained relatively under-addressed. The current study set out to examine native English and Persian speakers’ perceptions of and response to impoliteness in the production of the speech act of refusal. To this end, 90 native English speakers and 120 native Persian speakers were administered a written discourse completion task containing eight refusals that either observed politeness or contained various degrees of impoliteness. The results showed that native Persian speakers did not perceive any of the refusals to be impolite whereas three of the refusals were considered impolite by native English speakers. When reacting to impoliteness in refusals, native English speakers exploited a wider range of strategies than did Persian speakers. The results showed that social distance and power relations were of more significance for Persian speakers than for English speakers in perceiving the degree of impoliteness; however, in responding to an utterance perceived as impolite, English speakers were more likely to adopt offensive strategies to counter impoliteness, including positive and negative impoliteness strategies. These findings indicate both cross-cultural divergence and convergence in the perception of impoliteness and responses to impoliteness.
Identity, politeness and discursive practices in a changing world
Authors: Eslami Zohreh R. , Larina Tatiana Viktorovna , Pashmforoosh Roya
Published: April 2023

This special issue continues the discussion of the impact of culture on identity, communication, politeness, and discourse strategies (see Russian Journal of Linguistics 22 (4) 2018, 23 (4) 2019, 24 (2) 2020). The topic has become particularly relevant in the context of two multidirectional processes, i.e., globalization resulting from current geopolitical trends and technological advancements, which have encouraged the intensification of contacts between people, languages, and cultures; and deglobalization focused on the preservation of national cultures and development of a multipolar and multicultural world. In our introductory article, we attempt to trace the impact of communication technologies, language, and culture contacts on digital, face-to-face, and public communication in different settings and discourses and outline its influence on communication, language variation, and change. In this introductory article we present a summary of the contributions of our authors to the issue, which showed that the implications of globalization and language contact are multifaceted, they can have both positive and negative effects on language use, maintenance, and change, as well as on cultural identity and diversity. Pursuing these latter factors contributes to developing trends of deglobalization. Our authors invite the reader to reflect on these processes. In conclusion, we sum up their major findings and suggest a brief avenue for further research.
erros de Merkel na política externa alemã em relação à Rússia
Authors: Cunha Rael Robson
Published: April 2023

A política externa alemã voltada a Moscou durante o governo Merkel foi criticada por não ter dissuadido a Rússia a não cometer novas agressões contra a Ucrânia. O objetivo do artigo é analisar em que medida a Chanceler alemã errou na condução de sua política externa em relação à Rússia levando em consideração a Ostpolitik (uma política de Estado da Alemanha Ocidental direcionada ao Leste Europeu), a interdependência entre Alemanha e Rússia no setor de energia (com a participação de companhias de gás natural de ambos os países) e a função de ator mediador exercida por Berlim na crise de Ucrânia, com as assinaturas dos acordos de Minsk no âmbito do Grupo de Normandia. O método empregado é o process tracing, para análise da trajetória causal dos fatos ligados a Ostpolitik, a interdependência e a mediação. Conclui-se que Merkel errou em não reduzir a dependência alemã do gás natural russo, no entanto, a atuação geral da política externa da Alemanha não foi errônea ao considerar as relações com a Rússia no longo prazo, para a construção de uma arquitetura de segurança europeia mais estável.
The effect of the application of balanced performance measurement dimensions in strategic decisions in government universities
Authors: Shaheen Loona Mohammad Azmi
Published: April 2023

A balanced scorecard (BSC) with strategic decisions plays a vital role in achieving the effectiveness of business organizations. However, this paper aims to determine the impact of implementing the dimensions of the BSC on strategic decision-making in Jordanian universities. The study population included all Jordanian universities, while the sample consisted of 218 respondents from all managers working at administrative levels. The research concluded that there is a statistically significant effect on the dimensions of the BSC with its four axes (the financial axis, the beneficiaries’ axis (students, the local community), the growth and learning axis, and the internal operations axis) in making strategic decisions in Jordanian universities, where Al-Jubouri (2018), Tomizh et al. (2022) and Mazzuto et al. (2022) supported this finding. It is recommended to apply the BSC axes correctly and accurately during application in a way that clearly and comprehensively improves the strategic decision-making process.

The population in this study were manufacturing companies listed on the Indonesian stock exchange. The sample included 352 data sets from 174 companies. Secondary data utilized in this study were derived from the www.idx.co.id. Multiple linear regression for data analysis employed SPSS. This study uncovers that profitability and firm size have a positive effect on corporate philanthropy, while the audit committee has no significant effect on corporate philanthropy. This study provides implications for corporate management that increasing profitability will increase corporate philantrophy.
A Case of Acute Pulmonary Complication due to Botulinum Toxin: Patient with Central Pontine Myelinolysis Developed Acute Respiratory Distress Syndrome after Botulinum Neurotoxin Type A Injection Into Spastic Lower Extremity Muscles
Authors: Gökpınar Hasan Hüseyin , Urfalı Furkan Ertürk
Published: April 2023

Purpose Chemodenervation with botulinum neurotoxin type A (BoNTA) is the
preferred method for focal spasticity management among various treatment
options. While BoNTA injection is considered safe, its widespread use
and increasing evidence raise safety concerns. Case In this paper, we
present a patient with central pontine myelinolysis, a rare disease, who
developed Acute Respiratory Distress Syndrome (ARDS) on the third day
after BoNTA application to the spastic gastrocnemius muscle group and
required intubation in the intensive care unit due to this complication.
Conclusion To our knowledge, this is the first case reported in the
literature to develop an acute pulmonary complication after BoNTA
injection into spastic lower extremity muscles.
Will the blooming of artificial intelligence modify our approach to atrial fibrillation cure?
Authors: SCIARRA LUIGI , Scarà Antonio
Published: April 2023

Catheter ablation represents nowadays a cornerstone for the treatment of
atrial fibrillation. However, the benefit-risk ratio of this procedure
still needs to be significantly improved. Many strategies have been
proposed for this goal. Increased experience of operators and
technological advances appear to be crucial points. Very important in
this scenario is improving patients selection for ablation, as well. The
blooming of artificial intelligence and machine learning represents a
solid promise in many fields of medicine. Even in the field of atrial
fibrillation cure they could prove to have a strong impact. Further
prospective studies will surely help to define the real role of these
techonologies in the treatment of atrial fibrillation.
