Leptin in Dental Pulp and Periapical Tissues: A Narrative Review

Abstract: Leptin is a non-glycosylated 16 kDa protein synthesized mainly in adipose cells. The main function of leptin is to regulate energy homeostasis and weight control in a central manner. There is increasing evidence that leptin also has systemic effects, acting as a link between innate and acquired immune responses. The expression of leptin and its receptor in human dental pulp and periradicular tissues have already been described, as well as several stimulatory effects of leptin protein expression in dental and periodontal tissues. The aim of this paper was to review and to compile the reported scientific literature on the role and effects of leptin in the dental pulp and periapical tissues. Twelve articles accomplished the inclusion criteria, and a comprehensive narrative review was carried out. Review of the available scientific literature concluded that leptin has the following effects on pulpal and periapical physiology: 1) Stimulates odontogenic differentiation of dental pulp stem cells (DPSCs), 2) Increases the expression of dentin sialophosphoprotein (DSPP) and dentin matrix protein-1 (DMP-1), odontoblastic proteins involved in odontoblastic differentiation and dentin mineralization, 3) Stimulates vascular endothelial growth factor (VEGF) expression in human dental pulp tissue and primary cultured cells of human dental pulp (hDPCs), 4) Stimulates angiogenesis in rat dental pulp cells, and 5) Induces the expression of interleucinas 6 and 8 in human periodontal ligament cells (hPDLCs). There is evidence which suggests that leptin is implicated in the dentin mineralization process and in pulpal and periapical inflammatory and reparative responses

Analysis of the objects of learning and teaching perception of the virtual campus of the university of Extremadura

Nos encontramos en una sociedad en la que es cada vez más frecuente el uso de las tecnologías en educación. la educación superior ha evolucionado y ha extendido el paradigma del aprendizaje tradicional al uso de los campus virtuales como una herramienta de trabajo para el profesorado y el alumnado que les ayuda a tener la información disponible en tiempo real, a la vez que facilita la comunicación y el intercambio de actividades entre los miembros de la comunidad. Con nuestro estudio, nos hemos propuesto cómo objetivo analizar los objetos de aprendizaje y la percepción del profesorado sobre el campus virtual de la universidad de Extremadura a través de un diseño mixto de triangulación concurrente. la muestra ha estado compuesta por 252 docentes que nos han ayudado a observar que no existen diferencias significativas en relación al género, la edad y la rama de investigación sobre la percepción de los objetos de aprendizaje del campus virtual de la universidad de Extremadura. Se ha observado, que los principales puntos positivos del campus son que es principalmente utilizado cómo un repositorio de información y que mejora la comunicación entre alumnado y profesorado, mientras que sus principales puntos negativos son su funcionamiento y su interfazNowadays there is an intense use of technologies in education and it is raising. Higher education has evolved and extended the paradigm of traditional learning to the use of virtual campuses as a work tool for teachers and students that help them to have information available in real time, while facilitating communication and the exchange of activities among the members of the community. with our study, we have proposed how to analyze the objects of learning and the perception of the teaching staff about the virtual campus of the university of Extremadura through a mixed design of concurrent triangulation. the sample was composed by 252 teachers who have helped us to observe that there are no significant differences in relation to gender, age and the branch of research on the perception of the learning objects of the virtual campus of the university of Extremadura. It has been observed that the main positive points of the campus are that it is mainly used as a repository of information and it improves communication between students and teachers, while its main negative points are its functioning and its interfac

La búsqueda de información, la selección y creación de contenidos y la comunicación docente

The information and knowledge society has grown by leaps and bounds from the impulse of the distance education and the inclusión of the ICT in teaching. This implies that teachers must be and feel digitally competent to develop their work effectively. We have developed a study to analyze three parameters that define the digital competence in teachers of the province of Badajoz: the treatment of information, the selection and creation of content and teacher communication. Together with these variables, we have included sociodemographic parameters that help us to define the keys within the configuration of the digital teaching competence, such as the gender, the age, the experience, the máximun academic degree, the educational level of teaching and the population of the teaching municipality. The results have shown as a priority, teachers give greater importance to the treatment of information and that both the age and the academic qualifications of the teacher are fundamental variables, since as the age increases and the teacher's training improves, the variables that configure the digital competence, training teachers for a correct teaching activity in digital terms, and therefor, more adapted to the needs of the contemporary school.La sociedad de la información y del conocimiento ha crecido a pasos agigantados en la docencia a partir del auge de la educación a distancia y la inclusión de las TIC. Esto implica que los docentes deben ser, y sentirse digitalmente competentes para poder desarrollar su labor de forma eficaz. Hemos desarrollado un estudio para analizar tres de los parámetros que definen la competencia digital, en docentes de la provincia de Badajoz: el tratamiento de la información, la selección y creación de contenidos y la comunicación docente. Junto a estas variables, hemos incluido parámetros sociodemográficos que nos ayuden a definir cuáles son claves dentro de la configuración de la competencia digital docente, como son el género, la edad, la experiencia, la titulación académica máxima, el nivel educativo de docencia y la población del municipio de docencia. Los resultados han indicado que, prioritariamente, el profesorado otorga mayor importancia al tratamiento de la información y que, tanto la edad como la titulación académica del docente, son variables fundamentales, ya que, a medida que aumenta la edad y mejora la formación del docente, mejoran las variables que configuran la competencia digital, capacitando al profesorado para una labor docente correcta en términos digitales y, por ello, más adaptados a las necesidades de la escuela contemporánea

Toward Electrically Pumped Organic Lasers: A Review and Outlook on Material Developments and Resonator Architectures

Organic lasers have undergone decades of development. A myriad of materials with excellent optical gain properties, including small molecules, dendrimers, and polymers, have been demonstrated. Various resonator geometries have also been applied. While sharing the advantages of the solution processability and mechanical flexibility features of organic materials, organic optical gain media also offer interesting optical properties, such as emission tunability through chemical functionalization and inherent large optical gain coefficients. They offer prospects for different applications in the fields of bioimaging, medicine, chemo‐ and biosensing, anticounterfeit applications, or displays. However, the realization of electrically pumped organic lasers still remains a challenge due to the inherent drawbacks of organic semiconductors, e.g., modest carrier mobility, long‐lived excited‐state absorption, and extra losses which originate in the device (e.g., absorption from metal electrodes). Herein, the past developments of organic lasers are discussed, highlighting the importance of materials and cavities with regard to the goal of electrically pumped organic lasers. The latest progress and the possible ways to address the challenge are discussed

Origin of the exclusive ternary electroluminescent behavior of BN-doped nanographenes in efficient single-component white light-emitting electrochemical cells

White‐light‐emitting electrochemical cells (WLECs) still represent a significant milestone, since only a few examples with moderate performances have been reported. Particularly, multiemissive white emitters are highly desired, as a paradigm to circumvent phase separation and voltage‐dependent emission color issues that are encountered following host:guest and multilayered approaches. Herein, the origin of the exclusive white ternary electroluminescent behavior of BN‐doped nanographenes with a B3N3 doping pattern (hexa‐perihexabenzoborazinocoronene) is rationalized, leading to one of the most efficient (≈3 cd A−1) and stable‐over‐days single‐component and single‐layered WLECs. To date, BN‐doped nanographenes have featured blue thermally activated delayed fluorescence (TADF). This doping pattern provides, however, white electroluminescence spanning the whole visible range (x/y CIE coordinates of 0.29–31/0.31–38 and average color rendering index (CRI) of 87) through a ternary emission involving fluorescence and thermally activated dual phosphorescence. This temperature‐dependent multiemissive mechanism is operative for both photo‐ and electroluminescence processes and holds over the device lifespan, regardless of the device architecture, active layer composition, and operating conditions. As such, this work represents a new stepping‐stone toward designing a new family of multiemissive white emitters based on BN‐doped nanographenes that realizes one of the best‐performing single‐component white‐emitting devices compared to the prior‐art
