Adhesive dentistry has undergone remarkable advancements since its inception, fundamentally transforming restorative dental care. Initially marked by the development of early resins and etching techniques, adhesive dentistry has evolved to incorporate sophisticated materials and innovative techniques that significantly enhance clinical outcomes. The introduction of Bis-GMA resins in the 1960s improved mechanical properties and reduced polymerization shrinkage, paving the way for modern composite resins. These composites, enhanced by nanotechnology and advanced filler technology, provide superior strength, wear resistance, and esthetic qualities. Techniques such as selective enamel etching and multi-layering of adhesive systems have further improved bond strength and reduced technique sensitivity. The clinical applications of adhesive dentistry are extensive, ranging from direct and indirect restorations to cosmetic procedures and preventive measures. Direct composite restorations offer minimally invasive solutions with excellent esthetics, while indirect restorations such as inlays, onlays, and veneers benefit from strong, reliable bonds and improved durability. Cosmetic procedures, including veneers, achieve dramatic esthetic improvements with long-lasting results. Preventive applications, such as sealants, effectively protect against caries, especially in pediatric and high-caries-risk patients. The continuous refinement of materials and techniques has led to better clinical outcomes, increased patient satisfaction, and reduced need for invasive procedures. Advances in adhesive materials and methods have ensured that restorations not only mimic natural tooth structures but also maintain their integrity under functional forces. As research and development in adhesive dentistry continue to progress, the field is poised to offer even more innovative and effective solutions, further enhancing the quality of dental care. Overall, the evolution of adhesive dentistry underscores its pivotal role in modern dental practice, providing durable, esthetic, and reliable restorative options that meet the diverse needs of patients.

Tres encuentros textuales de Hero y Leandro
Authors: Navarrete Beltrán Daniel
Published: July 2024

Hero y Leandro es una de las pocas historias de ficción de la tradición grecolatina que, más que un mito, resulta ser una leyenda: una narración que, al tener elementos concretos de tiempo y espacio, es más verosímil para sus lectores o auditorio que otro tipo de relatos. Si bien varios autores griegos y latinos aludieron a ella, solamente tres obras la abordaron propiamente en la época antigua: en latín, dos de las Heroidas de Ovidio (XVIII y XIX); en griego, un epilio escrito por Museo en los límites de la Antigüedad y la Era Bizantina. Habrá que esperar hasta el Renacimiento para que otro gran poeta, Christopher Marlowe, sin duda inspirado en ellos dos, emprenda un nuevo tratamiento formal y original de la historia. Este artículo explora algunas características y problemas textuales de estas tres versiones.

The representation of disability in the Italian media: The case of Ansa
Authors: Melchior Claudio
Published: July 2024

The representation of disability in the media significantly influences the social perception of disability among the general population, as well as among individuals with disabilities themselves. This study focuses on the case of Ansa, the primary Italian press agency, to examine its portrayal of disability and persons with disabilities in the year 2022. Through the content analysis of a corpus comprising 1692 articles collected via keyword search, the research aims to draw a ‘map’ that can describe the disability narrative conveyed by Ansa. Key findings highlight Ansa’s narrative as displaying a form of under-representation of disability. Physical and mobility disabilities dominate the discourse, adhering to the common mediatic ‘hierarchy of disabilities’. But even more clearly, Ansa’s representation tends to be generic, abstract and lacking in specificity, thus presenting disability as a depersonalised and collective label. The narratives predominantly revolve around political interventions, funding, and institutional aid, with limited attention given to personal life stories that rarely attain national news status. Ultimately, the agency’s portrayal appears as a narrative of disability without the disabled persons, representing the phenomenon as a systemic issue that can be resolved through public frameworks and policies, with no direct involvement of those affected. This reinforces the notion that disability is a depersonalised problem that always needs external solutions.

Effect of Pit and Soil Types on Growth and Development, Nutrient Content and Fruit Quality of Pomegranate in the Central Deccan Plateau Region, India
Authors: Vadivel Rajagopal , Reddy Kotha Sammi , Singh Yogeshwar , Nangare Dhananjay D.
Published: July 2024

To enhance pomegranate production on marginal gravelly lands, standardized planting techniques were evaluated in an 8-year-old orchard. Trenching, wider pit excavation, pit digging, and auger digs with dimensions of 1 and 2 m were employed. Utilizing native soil from barren land, with or without spent wash, and mixing it with black soil up to 1 m deep, growth parameters, leaf nutrients, fruit production, and fruit quality were assessed. The trench and wider pit methods outperformed others, yielding greater above-ground biomass (>70.3 kg tree−1), root biomass (>24.5 kg, tree−1), and cross-sectional area (>3.30 m² tree−1). These methods also produced longer roots (>4.0 m tree−1) and higher leaf phosphorus (>0.28%) and potassium (>1.81%) levels, fruit juice content (>48.50%), and total soluble solids (>16.05°) compared to other planting methods. This resulted in higher and more sustainable fruit yield production under the trench and wider pit planting methods (>7.21 t ha−1). Similarly, the native and black soil mixture produced healthy fruit trees, improved fruit quality, and sustainably higher fruit yield over the native soil alone. In summary, the trench and wider pit methods (2–3 m³), combined with a soil mixture, are recommended for sustainable, high-quality fruit production in shallow gravelly terrains, thereby improving food security and the livelihoods of farmers in arid regions.
Targeting the Hippo-YAP/TAZ Signaling Pathway in Primary Liver Cancer Therapy
Authors: Wang Yina , Rui Liangyou
Published: July 2024

Liver cancer imposes a pervasive global health challenge, ranking among the most prevalent cancers worldwide. Its prevalence and mortality rates are on a concerning upward trajectory and exacerbated by the dearth efficacious treatment options. The Hippo signaling pathway, originally discovered in Drosophila, comprises four core components: MST1/2, WW45, MOB1A/B, and LATS1/2. This pathway regulates the cellular localization of the transcriptional coactivator YAP/TAZ (Yes-associated protein/PDZ-binding motif) through a series of enzymatic reactions. The Hippo/YAP/TAZZ pathway maintains a balance between cell proliferation and apoptosis, regu-lates tissue and organ sizes, and stabilizes the internal environment. Abnormalities of any genes within the Hippo signaling pathway, such as deletion or mutation, disturb the delicate balance between cell proliferation and apoptosis, creating a favorable condition for tumor initiation and progression. Mutations or epigenetic alterations in the Hippo signaling pathway components can lead to its inactivation. Consequently, YAP/TAZ becomes overexpressed and activated, promoting excessive cell proliferation and inhibiting apoptosis. This dysregulation is closely associated with the development of liver cancer. This review discusses the pivotal role of the Hippo signaling pathway in the pathogenesis and progression of liver cancer. By elucidating its mechanisms, we aim to offer new insights into potential therapeutic targets for effectively combating liver cancer.

New homogeneous bilayer membranes with a thin anion-exchange layer have been developed based on the copolymer of N,N-diallyl-N,N-dimethylammonium chloride (DADMAC) and ethyl methacrylate (EMA) on the surface of a membrane substrate made from polyfluorosulfonic acid (PFSA). The overall and partial current-voltage characteristics, as well as external and internaldiffusion limiting currents, were theoretically and experimentally investigated. Parameters such as specific conductivity, sorption, and diffusion permeability of individual membrane layers were determined, along with effective transport numbers and specific permselectivity of the bilayer homogeneous membranes in mixed solutions of calcium chloride and sodium chloride. It was found that applying a thin anion-exchange layer of DADMAC and EMA to the homogeneous membrane allows for the creation of a charge-selective bilayer membrane with enhanced selectivity towards monovalent metal cations. The specific selectivity of the bilayer membrane for sodium cations increases more than 6-fold (from 0.8 to 4.8). Verification of the obtained experimental data was performed within a four-layer mathematical model with quasi-equilibrium boundary conditions for the diffusion layer (I)/modifying layer (II)/membrane substrate (III)/diffusion layer (IV) in ternary NaCl+CaCl2 solutions.

Authors: Sun Guojin , Xu Linqian , Wang Qi
Published: July 2024

This study explores the impact of carbon fiber length and content on the rheological properties and performance of coatings used in lost foam casting. The investigation encompassed fiber lengths of 1 mm, 3 mm, and 6 mm, and fiber contents of 0.2%, 0.5%, and 0.8%. The effects on coating viscosity, shear stress, coating weight, and surface morphology were meticulously evaluated. The results demonstrate that incorporating carbon fibers significantly enhances coating viscosity and shear stress compared to fiber-free coatings, with more pronounced effects observed at higher fiber contents and longer fiber lengths. Nevertheless, excessive fiber content and length can lead to agglomeration, negatively impacting coating uniformity. Optimal fiber length and content were identified, striking a balance between improved rheological properties and coating performance. These findings provide critical insights for the development and industrial application of high-performance coatings in lost foam casting.

Published: July 2024

Background: Young people with intellectual developmental disabilities have a persistent delay in the development of executive functions. Virtual reality (VR) is increasingly being used as a cognitive intervention tool, with significant effectiveness demonstrated in different types of populations. Methods: This pilot study aims to investigate the impact of a cognitive training program utilizing VR on young adults diagnosed with intellectual developmental disability (IDD). The participants (N=15) served as their own control group and were assessed three times: weeks 0, 8 and 16, with a rest period (0-8 weeks) and an intervention period (8-16 weeks). The assessments included measures of cognitive function, provided by E-Prime®. Results: Overall, an improvement in working memory and inhibitory control was found after the intervention, but not in sustained attention. Conclusions: These findings suggest that VR-based cognitive training holds promise as an effective intervention for enhancing cognitive abilities in young adults with intellectual developmental disability.

Published: July 2024

As environmental and health concerns increase, the trend of sustainable agriculture moves toward using biological agents. About 60% of all biological fungicides have Trichoderma species as the active ingredient, with T. harzianum as the most common species in these products. However, the name T. harzianum has often been incorrectly used in culture collections, databases, and the scientific literature due to the division of the Harzianum Complex Clade (HCC) into more than 95 cryptic species with only one being named T. harzianum. In this study, strains previously identified as T. harzianum in three surveys of Trichoderma species from soils in South and Central America were reanalyzed using phylogeny based on tef1α, rpb2, and ITS loci and combined with the corresponding species in two other studies, where the species were correctly identified. Based on the results of the five surveys, T. afroharzianum, T. lentiforme, T. endophyticum followed by T. azedevio and T. harzianum were found to be the dominant species of the HCC in South and Central America. This is the first report of identifying dominant Trichoderma species within the HCC in South and Central American soil based on multiple studies, which will be useful in selecting strains within the complex clade for formulation of biocontrol and biofertilizer products in the continent.

Introduction: Laeverin is an extravillous trophoblast marker playing a significant role in the trophoblast migration. The purpose of this study was to evaluate the association between the amniotic and serum laeverin concentrations at 16-22 weeks of gestation and the fetal and placental ultrasound measurements in healthy, unaffected pregnancies. Materials and methods: This was a prospective cross-sectional study. Pregnant women with singleton pregnancies undergoing amniocentesis were recruited consecutively. Fetal structural malformations and/or aneuploidy were exclusion criteria. Fetal biometric parameters and placental growth/perfusion were measured in 44 high-risk pregnancies who had no pregnancy complication and any other chronic disease. Maternal serum and amniotic levels of laeverin were essayed with sandwich enzyme-linked immunosorbent assay. Results: Serum laeverin levels are decreasing slightly with the maternal age in mid-gestation. Serum laeverin level correlated negatively slightly with head size of the fetus with the gestational length at delivery (β=-0.38, 95% confidence interval (CI) -0.03-0.01), while the amniotic laeverin level correlated strongly with the abdominal circumference of the fetus (β=-0.64, 95% CI: -0.03-0.01). Furthermore, laeverin level in the amnion correlated moderately and positively with the placental volume (β=0.46, 95% CI: 0.01-0.08). Conclusions: Laeverin levels detected in the serum and in the amniotic fluid denotes the fetoplacental growth in uncomplicated high-risk pregnancies.
