Frecuencia de Maloclusión Dental en Escolares y su Relación con la Edad, el Sexo y la Escuela de Procedencia

Objetivo: Evaluar la frecuencia y distribución de maloclusión dental y su asociación con la edad, sexo y escuela de procedencia. Material y Métodos. Se llevó a cabo un estudio epidemiológico de carácter descriptivo, transversal y prolectivo, en el cual fueron examinados 399 escolares entre ocho y once años previa autorización de sus padres. La calibración del examinador se realizó para minimizar la variabilidad intra examinador y se observó un coeficiente de kappa de 0,997 para la valoración del tipo de oclusión de acuerdo a los criterios de Angle, Dewey y Anderson, valor que refleja un alto grado de confiabilidad. Resultados. El 75.7% mostró algún tipo de maloclusión dental, no mostrando asociación alguna con la edad, el sexo o la escuela de procedencia. La Clase I de acuerdo con Dewey-Anderson los tipos 1 y 2 fueron los más presentes. Conclusión. Se observó la posibilidad de que el nivel educativo sobre la maloclusión dental sea un factor más determinante en comparación con el poder adquisitivo de las familias de los niños, como factor de riesgo para desarrollar cualquier tipo de maloclusión dental. Objective: This paper focuses on evaluating the frequency and distribution of dental malocclusion and its association with age, sex, and school of origin. Material and Methods: A cross-sectional study was carried out on a sample of 399 schoolchildren between eight and eleven years old, and they were examined with the prior authorization of their parents. The examiner's calibration was performed to minimize intra-examiner variability. A kappa coefficient of 0.997 was observed for the assessment of the type of occlusion according to the criteria of Angle, Dewey and Anderson, which is a value that reflects a high degree of reliability. Results: 75.7% presented some type of dental malocclusion, showing no association with age, sex, or school of origin. Class I according to Dewey-Anderson types 1 and 2 were mostly present. Conclusion: In conclusion, it was observed that the educational level on dental malocclusion is a more decisive factor compared to the purchasing power of children's families. This, however, is considered as a risk factor for the development of some type of dental malocclusion

Innovative Crop Productions for Healthy Food: The Case of Chia (Salvia hispanica L.)

Chia (Salvia hispanica L.) is an ancient crop from Central America which has been recently rediscovered as a source of ω-3 and nutraceuticals in seeds. Besides traditional seed consumption, innovative uses of the plant seeds and leaves have been proposed based on the high protein content and the production of mucilage which lends itself to a range of applications. This chapter reviews research on the plant’s genetics and breeding, quality, and uses. Agronomic studies which have only recently started worldwide are also presented along with results from case studies in Basilicata

SCIPP: An Expanded Community of Practice - Community Publishing

SCIPP redefines and expands the existing notions about what makes for a vibrant and robust community of practice by partnering CSUSB students and professors with K-12 students, parents, and educators, along with committed community partners. SCIPP encourages curiosity in ways that leads to critical thinking, exploration, risk taking , confidence building, open-mindedness, and other personal traits that equip them with the softskills to be active, critical, and creative contributors to our communities. SCIPP pedagogy embraces our students\u27 collective wisdom and focuses on relational building where multi-directional communication is promoted and students are viewed as equal stakeholders in their own educations. SCIPP puts collaboration into action which in turn fosters community-based lifelong learning. SCIPP provides the open intellectual space for future university students (our K-12 students) to engage with existing university students in meaningful ways so as to sustain interconnected partnerships facilitating community engagement. It supports parents as experts in the education of their children and acknowledges parents as the first conduits to spark their children’s imagination while they actively participate in education enriching activities and programs. Everyone involved is committed to creating a secure and open atmosphere for dreaming, sharing, and learning. Together we explore the aspects of community publishing through collaborative learning in formal and informal settings relating to digital and printed medias

Effect of Pluronic P103 Concentration on the Simple Synthesis of Ag and Au Nanoparticles and Their Application in Anatase-TiO₂ Decoration for Its Use in Photocatalysis

Silver and gold nanoparticles were synthesized under environmentally-friendly reaction conditions by using a biodegradable copolymer and water as a solvent. The triblock copolymer Pluronic P103 was utilized as a stabilizing agent or soft template to produce Ag and Au nanoparticles (NPs) of different sizes. Moreover, in the synthesis of Au NPs, the polymer acted as a reducing agent, decreasing the number of reagents used and consequently the residues produced, hence, rendering the procedure less complicated. It was observed that as the concentration of the polymer increased, the size of the metallic NPs augmented as well. However, AgNPs and AuNPs prepared with 1 and 10 wt% Pluronic P103, respectively, showed a significant decrease in particle size due to the presence of polymeric soft templates. The hybrid materials (metal/polymer) were characterized by UV-Vis spectroscopy, DLS, and TEM. The pre-synthesized nanoparticles were employed to decorate anatase-TiO2, and the composites were characterized by DRS, XRD, BET surface area measurements, the TEM technique with the EDS spectrum, and XPS spectroscopy to demonstrate NPs superficial incorporation. Finally, methylene blue was used as a probe molecule to evidence the effect of NPs decoration in its photocatalytic degradation. The results showed that the presence of the NPs positively affected methylene blue degradation, achieving 96% and 97% removal by utilizing TAg0.1 and TAu10, respectively, in comparison to bare anatase-TiO2 (77%)
