Sympathy or strategy?
Authors: Dhaenens Laurens
Published: November 2023

The paper explores two Belgian art exhibitions that took place in Buenos Aires in 1946 and 1948: the Exposición de arte belga moderno and the Exposición de arte belga contemporáneo. Although these exhibitions appear to be part of the same cultural initiative showcasing Belgian art in Argentina after World War II, a closer examination reveals that they were distinct endeavors with differing institutional frameworks and objectives. The study offers a detailed analysis of the institutional context and discourse surrounding both exhibitions from a Belgian viewpoint. Specifically, it delves into the roles of Louis Piérard, the Argentine Commission for Intellectual Cooperation, the Belgian community in Buenos Aires, and the Belgian ministries of Foreign Affairs and Public Education. As such, it unravels the meaning and impact of the exhibitions in a post-war context. Ultimately, the paper demonstrates how these exhibitions reflect Belgium's evolving approach to international cultural diplomacy.

Radiological assessment and follow-up of a nonsurgically treated odontoid process fracture after a motor vehicle accident in Egypt: a case report
Authors: Abodahab Ahmad Mokhtar
Published: November 2023

An odontoid process fracture is a serious type of cervical spine injury. This injury is categorized into three types based on the location of the fracture. Severe or even fatal neurological deficits can occur due to associated cord injury, which can result in complete quadriplegia. Computed tomography is the primary diagnostic tool, while magnetic resonance imaging is used to evaluate any associated cord injuries. These injuries can occur either directly from the injury or during transportation to the hospital if mishandled. There are two main treatment approaches: surgical fixation or external nonsurgical fixation, with various types and models of fixation devices available. In this case study, computed tomography follow-up confirmed that external fixation can yield successful results in terms of complete healing, even in cases complicated by other factors that may impede healing, such as pregnancy.

Ion transport, mechanical properties and relaxation dynamics in structural battery electrolytes consisting of an imidazolium protic ionic liquid confined into a methacrylate polymer
Authors: Pipertzis Achilleas , Abdou Nicole , Xu Johanna , Asp Leif E. , Martinelli Anna , Swenson Jan
Published: November 2023

The effect of confining a liquid electrolyte into a polymer matrix was studied by means of Raman spectroscopy, differential scanning calorimetry, temperature-modulated differential scanning calorimetry, dielectric spectroscopy, and rheology. The polymer matrix was obtained from thermal curing ethoxylated bisphenol A dimethacrylate while the liquid electrolyte consisted of a protic ionic liquid based on the ethyl-imidazolium cation [C2HIm] and the bis(trifluoromethanesulfonyl)imide [TFSI] anion, doped with LiTFSI salt. We report that the confined liquid phase exhibits the following characteristics: (i) a distinctly reduced degree of crystallinity; (ii) a broader distribution of relaxation times; (iii) reduced dielectric strength; (iv) a reduced cooperativity length scale at the liquid-to-glass transition temperature (T g); and (v) up-speeded local T g-related ion dynamics. The latter is indicative of weak interfacial interactions between the two nanophases and a strong geometrical confinement effect, which dictates both the ion dynamics and the coupled structural relaxation, hence lowering Tg by about 4 K. We also find that at room temperature, the ionic conductivity of the structural electrolyte achieves a value of 0.13 mS/cm, one decade lower than the corresponding bulk electrolyte. Three mobile ions (Im+, TFSI-, and Li+) contribute to the measured ionic conductivity, implicitly reducing the Li+ transference number. In addition, we report that the investigated solid polymer electrolytes exhibit the shear modulus needed for transferring the mechanical load to the carbon fibers in a structural battery. Based on these findings, we conclude that optimized microphase-separated polymer electrolytes, including a protic ionic liquid, are promising for the development of novel multifunctional electrolytes for use in future structural batteries.

Published: November 2023

Background: Women had better dental and oral health than men because women had better fine motor skills and manual dexterity than men. Dental and oral health problems commonly found in adolescents were caused by plaque. Plaque is a soft layer tightly attached to the tooth’s surface. Plaque could be cleaned mechanically and chemically by brushing teeth using toothpaste. Toothpaste was divided into two types, namely herbal and non-herbal toothpaste which had ingredients that were efficacious for dental health. Purpose: Analyzing the differences in the effectiveness of herbal and non-herbal toothpaste against decreasing plaque index in adolescent women around 11-19 years at the Aisyiah Hikmah Zam-Zam Orphanage and Harapan Ibu Orphanage, Banjarmasin. Methods: This study used the true experimental method with a pre-and post-test control group design, using simple random sampling. Result: The Wilcoxon test in the herbal toothpaste group obtained a significant value of 0.001 (<0.05) which meant that there was a significant difference between the plaque index before and after using herbal toothpaste, while in the non-herbal toothpaste group a significant value of 0.124 (>0.05) which meant that there was no significant difference between the plaque index before and after using non-herbal toothpaste. The significance of the Mann-Whitney test in the herbal and non-herbal toothpaste group was 0.037 (<0.05), which meant that there were differences in the effectiveness of herbal and non-herbal toothpaste in adolescent women. Conclusion: Toothpaste with herbal content was more effective in lowering plaque index in adolescent women compared to non-herbal toothpaste. Keywords: Adolescent, Herbal Toothpaste, Nonherbal Toothpaste, Plaque Index

Published: November 2023

Background: Epulis is an epithelial tumor that is non-osteogenic. Epulis can be found in the oral cavity both on the gingiva and in the alveolar mucosa. Epulis is a benign enlargement of soft tissue. Granulomatous epulis is one type of epulis that is often found. This granulomatous epulis is a granulative tissue reaction with the characteristics of bleeding easily and having a reddish color. This epulis can disturb the patient both psychologically because there is a large mass in the oral cavity, causing it to be unaesthetic if it occurs in the anterior teeth area, disrupting the chewing process and even disrupting the speech process if it is in the posterior teeth.  Apart from causing discomfort to the patient, there are several types of epulis that can cause pain. Objective: To find out how to make a diagnosis of granulomatous epulis accompanied by treatment using a laser. Case: A 45 year old female patient came with complaints of enlarged gums since 1 year ago.  The patient initially used dentures, but currently the dentures cannot be used and the patient feels uncomfortable because he cannot chew food due to a large lump in the oral cavity. Case Treatment: At the first visit, an etiotropic phase is carried out in the form of elimination of local factors, then the patient is referred for supporting examinations in the form of panoramic radiography and FNA-B examination.  This examination functions to determine whether there is malignancy or not.  After the results showed no malignancy, we continued with the surgical phase in the form of excision of granulomatous epulis using a laser. Conclusion: Granulomatous epulis therapy using laser accompanied by removal of remaining tooth roots shows satisfactory therapeutic results. Keyword: Epulis, Epulis Granulomatosa, Excision, Laser

Health Communication plays an important role in the success of programs and policies implemented by the government. The rise of health conditions in the community, especially the stunting condition, which is worrying at this time, is a program that is carried out and implemented by the government to reduce the level of stunting conditions, especially in children. Considering that stunting is a government program that must be implemented by all health offices without exception. Therefore, to reduce stunting, the government, especially the puskesmas, must take part in this program so that it can reduce stunting. The purpose of this study was to find out the health communication strategy implemented by the puskesmas for the community, and how successful the program's policies were in reducing stunting rates. The research method used is a qualitative descriptive approach. The data collection techniques used in this study were in two ways, namely in-depth interviews, and documentation through observation with informants from the Head of Teluk Tamba Village, the Chairperson of the PKK in Teluk Tamba Village, and 6 parents of toddlers who experienced stunting. Data analysis techniques with observation and interviews. The results of the study show that the role of the puskesmas is very much needed for the success of the program's policies and that health communication between the puskesmas and the community runs very well and smoothly.

Cancer remains a significant global health challenge with limited treatment options beyond systemic therapies, such as chemotherapy, radiotherapy, and molecular targeted therapy. Immunotherapy has emerged as a promising therapeutic modality but the efficacy has plateaued, which therefore provides limited benefits to patients with cancer. Identification of more effective approaches to improve patient outcomes and extend survival are urgently needed. Drug repurposing has emerged as an attractive strategy for drug development and has recently garnered considerable interest. This review comprehensively analyses the efficacy of various repurposed drugs, such as transforming growth factor-beta (TGF-β) inhibitors, metformin, receptor activator of nuclear factor-κB ligand (RANKL) inhibitors, granulocyte macrophage colony-stimulating factor (GM-CSF), thymosin α1 (Tα1), aspirin, and bisphosphonate, in tumorigenesis with a specific focus on their impact on tumor immunology and immunotherapy. Additionally, we present a concise overview of the current preclinical and clinical studies investigating the potential therapeutic synergies achieved by combining these agents with immune checkpoint inhibitors.
pertenencia a organizaciones de autorregulación publicitaria como estrategia de relaciones públicas
Authors: Meléndez Ordóñez Javier Andrés
Published: November 2023

En el contexto de la publicidad y las relaciones públicas, se ha explorado el papel de la autorregulación y el cumplimiento voluntario de normas y regulaciones legales como estrategias para generar confianza y credibilidad en las organizaciones. Este documento presenta una revisión de artículos académicos recientes que examinan la relación entre la autorregulación publicitaria, el cumplimiento voluntario y la generación de confianza como una estrategia para crear relaciones positivas con los stakeholders organizacionales. Se destaca la importancia de la confianza como una emoción clave en la comunicación y se discuten los mecanismos mediante los cuales la autorregulación publicitaria puede influir en su generación, como la transparencia y la responsabilidad social. Los hallazgos sugieren que la autorregulación publicitaria y el cumplimiento voluntario pueden ser estrategias efectivas para fomentar la confianza y credibilidad en las organizaciones y mejorar su imagen ante los stakeholders. Sin embargo, no es un tema recurrente en las discusiones académicas actuales, particularmente en América Latina.
WITHDRAWN: Feasibility of using Gag proteins to reawaken dormant HIV infection based on bioinformatics analysis
Authors: Chen S.
Published: November 2023

By analyzing the effects of LRAs under epigenetic constraints and considering the variability in NF-κB sites, it is evident that the activation of NF-κB alone is not sufficient to trigger latent HIV. The author used bioinformatics methods to analyze the viral proteins and their PBS. The results show that the amino acid sequence ARG of Gag proteins of HTLV-1, HTLV-2, STLV-1 and STLV-2 match their PBS GGGGGCTCG in the 3'-to-5' direction and that the amino acid sequence SPR of Gag proteins of HIV-1, HIV-2, SIV and FIV match their PBS GGCGCCCGA in the 3'-to-5' direction. Related studies have shown that the genomic Gag/Gag-Pol complex recruits the LysRS/tRNA complex. The selective packaging of the tRNA primer requires HIV-1 Gag and Gag-Pol, and an interaction between LysRS and Gag is observed in vitro. In HIV-1, Gag/LysRS interaction depends on Gag sequences within the CTD of CA around amino acids 283-363 and motif 1 of LysRS around amino acids 208-259. It should be noted that the amino acid sequence SPR of the Gag protein is located at amino acids 148-150 within the NTD of CA, specifically at the NTD-NTD interface 1. This study demonstrates the NTD of CA of the Gag protein matching with PBS, while relevant studies have shown interactions between the CTD of CA of the Gag protein and PBS. Currently, it can be confirmed that the CA of the Gag protein interacts with PBS, providing new options for future treatment approaches beyond LRAs.
Plasma Powder Transferred Arc Additive Manufacturing of ((Fe,Ni)-Al) intermetallic alloy and resulting properties
Authors: Treutler Kai
Published: November 2023

Intermetallic alloys such as iron aluminides are of increasing interest for high-temperature applications due to their properties. However, their application potential is restricted by their limited machinability with conventional manufacturing methods such as milling. Arc-based additive manufacturing offers an approach to produce these materials to final contour or with very little post-processing. However, the properties of many intermetallic alloys, such as low toughness, require a special manufacturing process. Using a selected iron-nickel-aluminum intermetallic compound as an example, a possible process, including a subsidiary heat treatment, for the arc-based additive manufacturing of materials based on brittle intermetallic materials is presented. This process route could enable the production of structural components. In addition, some basic mechanical properties that can be achieved in a component are shown proportionally. These properties include initial investigations into the wear resistance of this kind of compounds. It is shown that these intermetallic compounds have a superior wear resistance compared tocommonly used co-base alloys but have a lower density compared to cobalt-basis alloys.
