Authors: Pocaan Jordan
Published: April 2024

Study purpose. This study examines the effect of a 16-week interval progressive circuit training program on the skill and health-related fitness of overweight university students.
Materials and methods. A total of 72 university students underwent health and skill-related fitness tests before and after a 16-week progressive circuit training program. Paired sample t-tests and Wilcoxon signed-rank tests were used to determine differences between pre- and post-tests.
Results. Significant decrease in BMI, cardiovascular endurance, agility, speed and reaction time was observed after a 16 week progressive circuit training program (p ≤ 0.05). In contrast, strength, flexibility, coordination and power increased significantly (p ≤ 0.05). The 16-week interval progressive circuit training programme has a positive effect on the physical fitness among the study participants.
Conclusions. The findings encourage further research into optimized training protocols, long-term sustainability of improvements, and tailored applications for specific population groups, ultimately advancing our understanding of the multifaceted benefits of interval progressive circuit training.
A CONVIVÊNCIA HARMONIOSA NAS MUITAS DIVERSIDADES
Authors: Santos Filho Bruno Freitas
Published: April 2024

Ao se tratar das questões de diversidade que vão desde as sociais, econômicas e culturais nos reportamos a inúmeros questionamentos, tais como: O que é identidade de gênero? O que é sexualidade? O que é transsexualidade? E tantos outros questionamentos dentro dessa temática. Este artigo tem por objetivo refletir sobre essa importante temática, uma vez que é de extrema importância sua discussão de forma benéfica e construtiva, servindo de suporte para amenizar os entraves da educação na atualidade, em especial o preconceito, a discriminação e a violência nas suas mais diversas facetas.

Authors:   Qujing Medical College, Qujing, China, Ma Xiaoyu
Published: April 2024

In order to analyze the user characteristic factors that affect the accurate recommendation of digital educational resources, optimize the user model and improve the accuracy of resource recommendation. In this paper, the interpretive structure Model (ISM) technology is used to clarify the logical relations among 13 key feature factors and establish the interpretive structure hierarchy model. Then the MICMAC model is used to analyze the dependence and driving force of each characteristic factor to determine its influence degree. The results show that user resource needs, resource preference and learning style are the direct factors affecting digital educational resource recommendation service. Individual attribute, learning motivation, social attribute, interactive preference, learning emotion and learning attitude are the core factors that affect the recommendation of digital educational resources. Information literacy, knowledge level, cognitive structure and learning input are the source factors that affect the recommendation of digital educational resources. Combining ISM analysis and MICMAC classification, the stability and driving force of the model level are gradually enhanced from the surface layer to the deep layer, and the dependence is gradually weakened.
Aprovechamiento de recursos turísticos de Ecuador para su puesta en valor: el Qhapac Ñan
Authors: Guerrero María Cristina
Published: April 2024

El turismo es uno de los principales sectores con gran potencial de crecimiento en las economías andinas. Frente al desafío de llevar a cabo un proceso de transformación productiva, varios países de la Región Andina han señalado al turismo como un sector con gran potencial de desarrollo en la región. Hoy en día, este sector ha tenido solamente un rol limitado en estas economías, el cual se vio aún más reducido por la pandemia. Pese al rol limitado que ha tenido este sector, su potencial de crecimiento es importante, especialmente dado el gran capital natural y cultural que hace únicos a los países andinos. Construyendo sobre esta idea, este estudio explora cómo el sector turismo en Ecuador puede jugar un papel más prominente. Esta es una de seis notas que analizan esta cuestión para cada uno de los países de la Región Andina Bolivia, Colombia, Ecuador, Perú y Venezuela y para la región de manera agregada. Específicamente, se explora el estado del sector, el marco institucional relevante en el país, así como un estudio de caso de activos con potencial a desarrollar.
Brevity is the Soul of Fic Microfiction, Microfic, and Shakespearean Abridgement in Online Fan Fiction
Authors: Pope Johnathan
Published: April 2024

Through a focus on Shakespeare fan fiction, this article discusses ‘microfic’ – short-form fan fiction – as a unique genre of microfiction. Sometimes consisting of fewer than ten words, microfiction relies on clever twists or epiphanies rather than character or plot development for its effect. Although microfic is equally brief and compact, as a genre of fan fiction, it is always engaged in a sustained dialogue with a fan object such as Shakespeare that serves to import whole plots, characters, and metatextual debates into the text with the mention of a name or place. As such, the brevity of microfic is illusory, as it continually draws on – and contributes to – the fan object and its archive. Unlike microfiction in general, micofic is never self-contained. Through an analysis of numerous Shakespeare microfics available in the Archive of Our Own fan fiction database, this article indicates the extent to which their silences are seldom silent.

Published: April 2024

Si bien es extendida la evidencia de los beneficios de la lactancia materna, diversos son los desafíos para iniciarla y sostenerla. Las empresas productoras de fórmulas infantiles utilizan estrategias de marketing violatorias de las regulaciones existentes, contribuyendo a su temprano abandono. Exploramos la exposición al marketing digital de las fórmulas infantiles en Argentina mediante el análisis de las interacciones de la población con las marcas y las huellas de dichas interacciones en conversaciones entabladas en grupos de Facebook durante 2022, desde un enfoque cualitativo basado en la etnografía digital. Los resultados muestran que las empresas despliegan tácticas elusivas de las regulaciones y buscan el contacto con las madres. Las usuarias no interactúan con las cuentas, pero están expuestas a sus estrategias dado el correlato entre los atributos del producto presentes en la publicidad con sus motivaciones y aspiraciones. Los mediadores entre el marketing y las madres son los profesionales médicos, utilizados como recursos del marketing. Concluimos que las autoridades deben promover nuevos acuerdos sobre las prácticas de los profesionales médicos y desarrollar regulaciones teniendo en cuenta los entornos digitales.

Authors: Emami Arjomand Mansoureh , Nasoohi Negin , Shabani Mohaddeseh
Published: April 2024

Objectives: This study assessed the effect of chlorhexidine (CHX) and isopropyl alcohol (IA) on immediate and late pushout bond strength (PBS) of fiber posts to dentin.
Materials and Methods: In this in vitro study, 54 single-canal premolars were endodontically treated, and randomly assigned to 3 groups (N=18) for root dentin conditioning with distilled water (control), 2% CHX, and 70% IA after post space preparation. Fiber posts were cemented with TheraCem self-adhesive cement, and each group was subdivided into two subgroups (N=9) for PBS measurement immediately after bonding, and after  5000 thermal cycles (5-55°C). The roots were then sectioned, and their PBS was measured. The mode of failure was evaluated under a stereomicroscope at ×40 magnification. Data were analyzed by repeated measures ANOVA and Tukey’s test (alpha=0.05).
Results: The highest PBS was noted in the IA group (21.12 MPa) after 24 hours and the lowest PBS belonged to the control group after thermocycling (7.48 MPa). The immediate and post-thermocycling PBS were significantly lower in the control group than the CHX group (P<0.05). The PBS in both the control and CHX groups was lower than that in the IA group (P<0.001).  Regardless of the type of detergent, a significant reduction in PBS was observed after thermocycling (P<0.003). The PBS significantly decreased from the cervical towards the apical region in all groups (P<0.001).
Conclusion: According to the results, application of IA before the self-adhesive cement effectively improved the immediate and late PBS, and was significantly more effective than CHX.

This article presents a new extension of the three-parameter log-logistic distribution, the so-called heavy-tailed log-logistic (HTLL) distribution. Some important mathematical properties of the new HTLL distribution are calculated. In addition, some numerical results of moments for the HTLL distribution are calculated. Extensive simulations were performed to investigate the estimation of the model parameters using many established approaches, including maximum likelihood (ML), least squares (LS), weighted least squares (WLS), Cramer-von Mises (CVM), Anderson-Darling (AD), and right-tail Anderson-Darling (RTAD). The simulation results show that the AD approach has the highest efficiency among these approaches. The usefulness of the newly proposed model is demonstrated by analyzing two real data sets.

Authors: Ferreira Ayrana Gomes , Coelho George Leonardo Seabra
Published: April 2024

A crescente influência das mídias digitais em nossas vidas coloca as questões cotidianas no centro dos discursos online, dessa forma, o presente trabalho foi desenvolvido com o objetivo de apresentar uma análise do discurso de ódio. A metodologia da netnografia nos ajudou no mapeamento das dinâmicas nos processos de comunicação entre os seguidores e não seguidores das plataformas digitais, onde observamos as interações online como, por exemplo, comentários, postagens e discussões em fóruns específicos, buscando compreender a dinâmica social e cultural que alimenta a gordofobia digital. A pesquisa também investigou as políticas de moderação das plataformas e seu papel na contenção desse discurso prejudicial, bem como analisou o equilíbrio entre a liberdade de expressão e a segurança online. Os resultados obtidos demonstram a presença ubíqua das mídias digitais em nossa vida cotidiana e sua influência na amplificação de questões rotineiras. Além disso, este estudo destaca que o debate sobre o discurso de ódio não está confinado apenas ao campo jurídico, mas também é uma questão relevante na historiografia, mostrando caminhos para que tais temas sejam esmiuçados em sala de aula de acordo com Base Nacional Comum Curricular (BNCC).

Published: April 2024

As indústrias de tintas e de abate de bonvinos tem chamado atenção para as práticas de reúso em virtude da quantidade de águas residuárias geradas. Além disso, o efluente da indústria de abate de bovinos apresenta elevada carga de nutrientes, assim como, o efluente da indústria de tintas apresenta índice elevado de carbonato, uma espécie química importante para a fertilidade e adequação do pH do solo. Dessa forma, a utilização combinada desses efluentes pode ser uma alternativa viável de produzir uma água com características físico-química e microbiológicas úteis para o setor agrícola. No entanto, além da avaliação nutricional do solo após a fertirrigação, uma informação imprescindível para determinar a viabilidade desta proposta é a quantificação da sua toxicidade aos ecossistemas, o que justifica a necessidade dos ensaios ecotoxicológicos para a obtenção de dados concretos quanto a segurança ambiental para o uso combinado destes efluentes na agricultura. Desta forma, neste trabalho foi utilizado o organismo Girardia tigrina, como um bioindicador de contaminação para ecossistemas de água doce. Como resultado observou-se que um efluente combinado com 50% de efluente de abate de bovinos e 50% de efluente de indústria de tintas, apresentou uma CL50 na concentração de 80% após 24h de exposição.

Changing the Landscape of Solid Tumor Therapy From Apoptosis-Promoting to Apoptosis-Inhibiting Strategies
Authors: Mirzayans Razmik
Published: April 2024

The many limitations of implementing anticancer strategies under the term “precision oncology” have been extensively discussed. While some authors propose promising future directions, others are less optimistic and use phrases such as illusion, hype and false hypotheses. The reality is revealed by practicing clinicians and cancer patients in various online publications, one of which has stated that “in the quest for the next cancer cure, few researchers bother to look back at the graveyard of failed medicines to figure out what went wrong.” The message is clear: novel therapeutic strategies with catchy names (e.g., synthetic “lethality”) have not fulfilled their promises despite decades of extensive research and clinical trials. The main purpose of this review is to discuss key challenges in solid tumor therapy that surprisingly continue to be overlooked by the nomenclature committee on cell death and numerous other authors. These challenges include: the impact of chemotherapy-induced genome chaos (e.g., multinucleation) on resistance and relapse, oncogenic function of caspase 3, cancer cell anastasis (recovery from late stages of apoptosis), and pitfalls of ubiquitously used preclinical chemosensitivity assays (e.g., cell “viability” and tumor growth delay studies in live animals) that score such pro-survival responses as “lethal” events. Studies outline herein underscore the need for new direction in the management of solid tumors.
Optimization of Lithium Metal Anode Performance: Investigating the Interfacial Dynamics and Reductive Mechanism of Asymmetric Sulfonylimide Salts
Authors: Feng Shuang , Yin Tianxiu , Bian Letao , Liu Yue , Cheng Tao
Published: April 2024

Asymmetric lithium salts, such as Lithium (difluoromethanesulfonyl)(trifluoromethanesulfonyl)imide (LiDFTFSI), have been demonstrated to surpass traditional symmetric lithium salts with improved Li+ conductivity and the capacity to generate stable solid electrolyte interphase (SEI) while maintaining compatibility with aluminum (Al0) current collector. However, the intrinsic reductive mechanism through which LiDFTFSI influences battery performance remains unclear and under debate. Herein, the detailed SEI reactions of LiDFTFSI-based electrolytes were investigated by combining density functional theory and molecular dynamics, aiming to clarify the formation process and atomic structure of SEI. Our results show that asymmetric DFTFSI– weakens the interaction between carbonate solvents and Li+, and substantially alter the solvation structure, exhibiting a well-balanced coordination capacity to bis(trifluoromethanesulfonyl)imide (TFSI–). Nanoseconds hybrid molecular dynamics simulation further reveals that the preferential decomposition of LiDFTFSI produces sufficient LiF and Li2O to facilitate a robust SEI. Moreover, the abundant F– generated from LiDFTFSI decomposition accumulates on the Al surface and subsequently combines with Al3+ from the current collector to form AlF3, potentially inhibiting corrosion of the current collector. Overall, these findings elucidate how LiDFTFSI regulates the solvation sheath and SEI structure, advancing the development of high-performance electrolytes compatible with current collector.

Published: April 2024

In this study, low density silica nanoparticles (LDS) were synthesized and used as a heterogeneous catalyst for dye removal and nanosensors for hydrogen peroxide detection. Organosilane silica nanoparticles were produced and calcinated at 400°C to produce low density particles. SEM, FTIR, DLS, and zeta potential analysis were used to characterize the generated particles. The results confirmed that the particle size, charge, and density varied with the APTES concentration. The results showed that at lower APTES concentrations, small particles (70-75 nm) were created, but at higher concentrations, larger particles (420-430 nm) were produced. The particle density changed depending on the APTES content. The UV absorption spectra of APTES-added samples varied significantly between 440 and 480 nm.The dye removal activity was measured using crystal violet dye; under UV irradiation, the particles destroyed up to 90% of the dye within 120 minutes, and the kinetics were also detailed. HRP-coated LDS was used as a nanosensor for detecting H2O2. Results indicated linearity of 5´10-10 ~ 1´10-5 (M) (R2=0.995), and a detection limit of 5 nm mol. The milk was spiked with H2O2 at varied concentrations and used as detections for the actual sample analysis. Finally, this paper describes the simplest way for producing tailored low-density silica, which is ideal for biomedical and drug delivery applications..

Published: April 2024

The magnitude of the penetration error is critical in determining whether a high-speed railway tunnel project can effectively break through as per the project's predictions. Controlling the lateral penetration error is essential in managing the overall penetration error. Estimating the accuracy of the penetration error based on control measurement results and conducting penetration measurements after evaluation are effective measures to ensure the quality of tunnel projects. Taking the first-level risk tunnel of Luojiashan in the ZWZQ-7 section of Zhengwan High-speed Rail as an example, this paper explores methods for laying out control points outside and inside the tunnel based on measurement specifications, aiming at controlling the penetration error limit. It also discusses data processing techniques using different software and estimating tunnel penetration error accuracy based on control measurement results.

Vertical transmission, the transfer of pathogens across generations, is a critical mechanism for the persistence of plant viruses. The transmission mechanisms are diverse, involving direct invasion through the suspensor and virus entry into developing gametes before achieving symplastic isolation. Despite the progress in understanding vertical virus transmission, the environmental factors influencing this process remain largely unexplored. We investigated the complex interplay between vertical transmission of plant viruses and pollination dynamics, focusing on the common bean (Phaseolus vulgaris). The intricate relationship between plants and pollinators, especially bees, is essential for global ecosystems and crop productivity. We explored the impact of virus infection on seed transmission rates, with a particular emphasis on the bean common mosaic virus (BCMV), bean common mosaic necrosis virus (BCMNV), and cucumber mosaic virus (CMV). Under controlled growth conditions, BCMNV exhibited the highest seed transmission rate, followed by BCMV and CMV. Notably, bee-pollinated BCMV-infected plants outdoors showed a reduced transmission rate compared to self-pollinated plants. This highlights the influence of pollinators on virus transmission dynamics. The findings provide valuable insights into the species-specific nature of virus seed transmission and underscore the importance of considering environmental factors, such as pollination, in understanding and managing plant virus spread.

Purpose Given oxysterol binding protein like 10’s (OSBPL10) known involvement in lipid transport and oncogenic activity in other tumors, we aimed to elucidate the mechanism underlying its contribution to pancreatic cancer progression.
Methods We employed data from the Gene Expression Omnibus database. A series of assays, including CCK8,colony formation,wound healing and transwell, were conducted to assess the impact of OSBPL10 on the proliferation and metastatic capacities of pancreatic cancer cells. Flow cytometry was employed to evaluate the influence of OSBPL10 on macrophages. Co-immunoprecipitation , mass spectrometry, and western blot assays were utilized to investigate the potential mechanisms of OSBPL10 activity.
Results The study revealed a significant uoregulation of OSBPL10 in pancreatic cancer cells, correlating with poor prognosis. OSBPL10 knockdown attenuated pancreatic cancer cells proliferation and metastasis, while its overexpression enhanced these malignant behaviors. Notably, OSBPL10 knockdown promoted the transformation of M2 macrophages into M1 macrophages in the pancreatic cancer microenvironment. Mechanistically, hypoxia-induced upregulation of OSBPL10 through interaction with hypoxia-inducible factor 1-α in the promoter region was identified. Additionally, OSBPL10 directly bound to CNBP, mediating CNBP expression and ultimately regulating the proliferation and metastasis capacity of pancreatic cancer cells, as well as influencing macrophage polarization.
Conclusions This study provides comprehensive insights into oncogenic role of OSBPL10 in pancreatic cancer, uncovering key mechanisms involving hypoxia, HIF-α,and CNBP. The finding suggest that OSBPL10 plays s crucial role in promoting pancreatic cancer progression, making it a potential therapeutic target for intervention in this malignancy.

In the recent past, Forest fires are a severe environmental risk that occurs continually in the Mediterranean region. The province of Bejaia, located in the northeastern part of Algeria, is an illustrative example of forest fires. In this research, we used multi-source remote sensing data (MODIS and Landsat 8) and the Google Earth Engine (GEE) platform to assess the impact of forest fires in August 2021. In addition, the Differenced Normalized Difference Vegetation Index (dNDVI) and Differenced Normalized Burn Ratio (dNBR) were employed to identify fire-affected areas and estimate the degree of damage. Our results showed that 2.24% of the study area experienced high fire severity, covering 7223 hectares. This high fire sensitivity is probably due to topographic and environmental factors. This study demonstrates how Geographic Information System (GIS) and remote sensing can be valuable tools for forest managers, helping them make better decisions for sustainable forest management.

Background
Medical nutritional therapy is the basis of the treatment of type 2 diabetes mellitus. To deeply explore the nutritional literacy status and influencing factors of type 2 diabetes mellitus patients, to understand the nutritional needs of patients, and to provide a basis for strengthening the nutritional literacy level of diabetes mellitus patients in China, improving self-management, and improving the quality of life.
Methods
A phenomenological research method was used to conduct semi-structured interviews with 13 patients with type 2 diabetes mellitus and 10 healthcare professionals, and the Colaizzi 7-step method was used to analyze the data and refine the themes.
Results
Four themes and 12 sub-themes were summarized: lack of beliefs about nutrition management (ambiguity about the role of nutrition management, lack of willingness to gain in-depth knowledge about nutrition, lack of awareness of dietary nutritional risks, and poor dietary nutritional adherence); insufficient knowledge and skills in nutrition management (misconceptions about nutritional knowledge, lack of skills in nutritional combinations and food exchanges, and insufficient ability to cope with difficulties); and insufficient ability to interact with nutritional information (active less access to nutritional knowledge, limited utilization of perceived surrounding resources, transformation and utilization of nutritional information); and insufficient ability to critique nutritional information (difficulty in identifying nutritional information, selective acceptance of nutritional information).
Conclusion
The overall nutritional literacy of patients with type 2 diabetes mellitus is insufficient, the perception of nutritional management is weak, nutritional knowledge and skills are more lacking, the interactive and critical ability of nutritional information needs to be improved, and the patients are unable to carry out effective disease management; therefore, it is necessary for healthcare professionals to improve the nutritional literacy of the patients for the self-management and healthy outcomes by targeting the weak points.
