    [EN] The classical methods used to teach practical subjects in today's university context mean that students are not very motivated when they come to the laboratory. This fact generates the need for teachers to look for new alternatives that can improve learning. Social networks have become very important in today's society and can be a good tool to use in university education. This research was carried out in the academic year 2021-2022 in the subject of Bromatology, which is taken in the second year of the first term of the Degree in Human Nutrition and Dietetics at the Catholic University of Valencia San Vicente M谩rtir, in a population sample of 40 students. In the practical session, a bromatological analysis of different flours was carried out. The general objective of this study was to research the use of Instagram as a tool to encourage motivation, the learning of part of the practical knowledge of the subject and to promote collaborative work. All the students stated that the incorporation of the use of the social network as a means of disseminating their photographs, and the creation of the scientific photography competition through this tool produced a high degree of motivation in them, and 96% recognised that this methodological strategy improved the assimilation of the concepts taught in the practical content of the subject and encouraged teamwork.[ES] Los m茅todos cl谩sicos utilizados para impartir las pr谩cticas de las asignaturas en el contexto universitario actual, hace que los alumnos acudan al laboratorio poco motivados. Este hecho genera la necesidad de que los docentes se planteen buscar nuevas alternativas que puedan mejorar el aprendizaje. Las redes sociales han adquirido un gran protagonismo en la sociedad actual y pueden ser una buena herramienta a utilizar en el 谩mbito educativo universitario. Esta investigaci贸n se realiz贸 en el curso acad茅mico 2021-2022 en la asignatura de Bromatolog铆a que se cursa en segundo en el primer cuatrimestre del Grado de Nutrici贸n Humana y Diet茅tica en la Universidad Cat贸lica de Valencia San Vicente M谩rtir en una muestra poblacional de 40 alumnos. En la sesi贸n pr谩ctica se realiz贸 un an谩lisis bromatol贸gico de diferentes harinas. El objetivo general que se plante贸 en este estudio, fue investigar el uso de Instagram como herramienta para incentivar la motivaci贸n, el aprendizaje de parte de los conocimientos pr谩cticos de la asignatura y fomentar el trabajo colaborativo. Todos los alumnos manifestaron que la incorporaci贸n del uso de la red social como medio de divulgaci贸n de sus fotograf铆as, y la creaci贸n del concurso de fotograf铆a cient铆fica a trav茅s de esta herramienta produjo en ellos alto grado de motivaci贸n, adem谩s el 96% reconocieron que esta estrategia metodol贸gica mejor贸 la asimilaci贸n de los conceptos impartidos en los contenidos pr谩cticos de la asignatura y foment贸 el trabajo en equipo.Sempere Ferre, F.

    El hongo pat贸geno del arroz Drechslera oryzae se inocul贸 en un mismo sustrato junto a Trichoderma harzianum en distintas condiciones medioambientales. Los mecanismos ejercidos por T. harzianum para antagonizar a D. oryzae y que en algunos casos actuaron sin茅rgicamente fueron: competencia por el espacio y los nutrientes, micoparasitismo y posible antibiosis. La capacidad antagonista de T. harzianum aument贸 con los valores de temperatura y actividad del agua.The rice pathogen Drechslera oryzae and the antagonistic fungus Trichoderma harzianum were inoculated in the same substratum at different environmental conditions. The mechanisms exerted by T. harzianum as antagonist over D. oryzae and that on some occasions acted sinergically were: competitiveness for space and nutrients, mycoparasitism and a possible antibiosis. The antagonistic capacity of T. harzianum was higher as the values of water activity and temperature were increasing.Ciencias Experimentale

    [EN] The European Union is promoting regulatory changes to ban fungicides because of the impact their use has on the ecosystem and the adverse effects they can pose for humans. An ecofriendly alternative to these chemicals to fight against fungal species with low toxicity is essential oils and their compounds extracted from aromatic plants. The purpose of this study was to evaluate the in vitro antifungal capacity of the botanical compounds eugenol, carvacrol, thymol, and cinnamaldehyde, and the synergy or antagonism of their mixtures, against Botryotinia fuckeliana and Rhizoctonia solani. Different bioassays were performed at doses of 300, 200, 150, and 100 mu g/mL using pure commercial compounds and their combination in potato dextrose agar culture medium. Growth rate and the mycelium growth inhibition parameters were calculated. Phenolic compounds and their combination inhibited the development of species at the different concentrations, with fungicidal or fungistatic activity shown under almost all the tested conditions. When comparing the growth rates of the species in the control plates and treatments, the statistical analysis showed that there were statistically significant differences. The mixture of compounds improved fungicidal activity against the studied species and at a lower concentration of monoterpenes.This research was funded by the Spanish Ministry of Economy and Competitiveness, Programme-oriented Societal Challenges 2016-2019, grant number AGL2016-76699-R-AR.Sempere-Ferre, F.; Asamar, J.; Castell-Zeising, V.; Rosello Caselles, J.; Santamarina Siurana, MP.

    This is an Accepted Manuscript of an article published by Taylor & Francis in All Life (Online) on 05 Jan 2022, available online: http://www.tandfonline.com/10.1080/26895293.2021.2022007[EN] The postharvest life of most fruit, vegetables and cereals is limited by fungal proliferation. The chemical composition of Mentha piperita, M. spicata and M. suaveolens essential oils (EO), and the antifungal activity against four pathogenic and post-harvest fungi isolated from food, were herein investigated to evaluate their potential as natural food preservatives. The EO were obtained by hydrodistillation of aerial parts leaves, stems and inflorescences (except for peppermint oil, which was purchased in a specialized store) and submitted to GC-MS and GC-FID analysis. Regarding the EO composition, carvone (41.1%) and limonene (14.1%) were the major compounds in M. spicata, menthol (47.0%) and menthone (23.1%), as well as other menthol derivatives (neomenthol -3.6%- and menthofurane -3.7%-) in M. piperita, and piperitone oxide (40.2%) and piperitenone oxide (31.4%) in M. suaveolens. Botryotinia fuckeliana was the most sensitive fungus. The three studied EO inhibited growth by 92驴100%. The highest dose of M. suaveolens EO, 400 驴g/mL, produced 100% MGI in all the studied fungi, except Fusarium oxysporum with 94.21%. The M. suaveolens EO can be considered to develop a low-risk enviro-friendly botanical biofungicide.The authors also thank the Spanish Type Culture Collection (CECT) for providing the molecular strain identification equipment.

    Fundamentos: El S铆ndrome de Phelan-McDermid es una enfermedad poco frecuente de origen gen茅tico causada por la deleci贸n del extremo terminal del cromosoma 22 regi贸n q13.3 o por mutaciones puntuales que afectan al gen SHANK3. Los objetivos de este trabajo fueron determinar la prevalencia de la enfermedad en la poblaci贸n espa帽ola, establecer la distribuci贸n geogr谩fica del s铆ndrome entre las distintas comunidades aut贸nomas, dilucidar el rango de edad en el que existen m谩s pacientes y estudiar la relaci贸n enfermedad-sexo as铆 como la edad media al diagn贸stico. M茅todos: Para la investigaci贸n se reclutaron pacientes diagn贸sticados con la enfermedad durante doce a帽os en todo el territorio espa帽ol. La informaci贸n cl铆nica de los pacientes se obtuvo de los m茅dicos de referencia mediante dos cuestionarios estandarizados completados con datos de los informes m茅dicos y la entrevista a los padres. El diagn贸stico molecular de la enfermedad se realiz贸 utilizando diferentes formatos de microarrays. Los datos se trataron utilizando Microsoft Excel y Statgraphics Centurion XVII. Resultados: Actualmente en Espa帽a existen 201 personas diagnosticadas con la enfermedad siendo su prevalencia de 4x10-4/10.000 habitantes. La comunidad con m谩s pacientes diagnosticados fue Madrid y no hubo diferencias significativas en cuanto al sexo y la enfermedad, la edad media al diagn贸stico se sit煤a en torno a los 6,67 a帽os. Conclusiones: La prevalencia de la enfermedad en Espa帽a es muy baja pudi茅ndose afirmar que es muy probable que en la poblaci贸n existan m谩s personas con este s铆ndrome.Background: Phelan-McDermid syndrome is a rare genetic condition caused by a deletion of the terminal end of chromosome 22 in the 13.3 region, as well as, by point mutations within SHANK3 gene. The aims of this research were to determine the prevalence of the disease in the Spanish population, to establish the geographical distribution of the syndrome among the different autonomous communities, to elucidate the age range that affects more patients, to study the disease-sex relationship, as well as the age at diagnosis. Methods: For the research, patients diagnosed with the disease for twelve years were recruited throughout the Spanish territory. The clinical patient information was obtained from the referral doctors using two standardized questionnaires completed with data from the medical reports and the interview with the parents. The molecular diagnosis of the disease was carried out using different formats of microarrays. Data were processed using Microsoft Excel and Statgraphics Centurion XVII. Results: Currently in Spain there are 201 people diagnosed with the disease. Currently in Spain there are 201 people diagnosed with the disease, its prevalence being 4x10-4/10,000 inhabitants. The community with the most diagnosed patients was Madrid and there were no significant differences in terms of sex and disease, the mean age at diagnosis was around 6.67 years. Conclusions: The prevalence of the disease in Spain is very low, and it can be stated that it is very likely that there are more people with this syndrome in the population.Medicin

    [EN] The term superfoods used in marketing in recent years has been used to describe foods with questionable health benefits, and there is no agreed definition. Television, internet, influencers, actors, etc. encourage and reinforce their consumption in the general population. The general objective of this project was to improve scientific knowledge of this type of food by transforming students into scientific influencers or popularisers. The experiment was carried out in the Bromatology subject of the Degree in Human Nutrition and Dietetics (Catholic University of Valencia San Vicente M谩rtir) during the 2018-2019 academic year with a population sample of 37 students. The title of the project was: "Superfoods: truth or lie? and it was subsidised by this university and awarded as good teaching practice. The project was carried out during the whole term as a group and was structured in two phases: delivery of a written document and editing of a video. The degree of participation in the work registered statistically significant differences when compared with other tasks carried out in different academic years. The implementation of this methodology contributed to the development of different competences through the learning outcomes established in the subject and the objectives initially set were met. The project improved the scientific knowledge of superfoods and led to an increase in motivation, enjoyment and involvement of the students.[ES] El t茅rmino superalimentos utilizado a nivel de marketing en los 煤ltimos a帽os, se 聽ha utilizado para describir alimentos con beneficios cuestionables sobre la salud, no existiendo una definici贸n consensuada al respecto.
