Empleo de Socrative para la evaluación del trabajo previo en asignaturas prácticas de laboratorio
2019
[EN] University students of experimental sciences degrees usually go to the laboratory of practices without having prepared the corresponding activity. This fact leads to a poor preparation of them translated into an effective loss of time available for experimentation, and a reduced acquisition of knowledge and skills, among other aspects. In order to solve this problem, in the present communication, the use of on-line questionnaires using the Socrative platform is described to be used as a prior evaluation system to access the laboratory. The results obtained show that the proposed didactic strategy significantly improves the preparation of the students upon arrival to the laboratory, as …
El descubrimiento de nuevos fármacos, concepto umbral en farmacología.
2021
[EN] The so-called “threshold concepts” are present in all areas of study. Its acquisition by the student represents a milestone in the advancement of the conceptual understanding of a subject. They are often difficult to learn, but when they are overcome they generate a reconceptualization that allows progress and deepening in the subject of study. We present an activity designed to develop a key threshold concept in pharmacology, the drug discovery process. To do this, we develop a practical laboratory project that will integrate both the extraction and search for active ingredients and the simulation of some aspects of their clinical trials in the phase I.
LaboratorioRPGDocente: Un game-based learning para combatir la situación causada por la COVID-19 en instituciones educativas.
2021
[EN] Due to the pandemic caused by COVID-19, several educational institutions have been forced to close their facilities, and practical courses -such as laboratory practices- were impossible to carry out. Game-based learning can be found among many different digital learning techniques, and it consists in teaching the contents as a transversal inmersive element. This work will be focused on a simulation videogame, which allows the students to understand the simulated environment and to develop certain skills based on their interaction with the game interface. One of the main characteristics of these kind of video games is their high degree of realism. More specifically, in this project, stu…
Cellusim: Un simulador 3D en entorno videojuego para la docencia del laboratorio de cultivos celulares
2018
[EN] Cell cultures allow the maintenance of living cells outside the body. This technique is fundamental to study the biological, biochemical and physiological properties of cells and can be used as an experimental model in vitro in the field of biomedical research. The teaching in the laboratory of this technique presents numerous difficulties at a practical, logistical and economic level. On the other hand, the learning of cell culture protocols is an important part of the student's training in Cell Biology. Based on the routine practices carried out within a cell culture laboratory, we have developed the virtual 3D simulator of a cell culture laboratory "Cellusim". In "Cellusim" you can …
Neonicotinoids from coated seeds toxic for honeydew-feeding biological control agents
2021
Seed coating (‘seed treatment’) is the leading delivery method of neonicotinoid insecticides in major crops such as soybean, wheat, cotton and maize. However, this prophylactic use of neonicotinoids is widely discussed from the standpoint of environmental costs. Growing soybean plants from neonicotinoid-coated seeds in field, we demonstrate that soybean aphids (Aphis glycines) survived the treatment, and excreted honeydew containing neonicotinoids. Biochemical analyses demonstrated that honeydew excreted by the soybean aphid contained substantial concentrations of neonicotinoids even one month after sowing of the crop. Consuming this honeydew reduced the longevity of two biological control …
Didattica e sviluppo delle competenze del Maestro. Docenti e studenti protagonisti in un percorso di ricerca
2010
Il volume affronta il tema dell’integrazione delle lezioni, dei laboratori e del tirocinio nella formazione dei futuri maestri, presentando concrete modalità di interazione tra le esperienze maturate dagli studenti del Corso di Laurea in Scienze della Formazione Primaria durante il percorso universitario. Nel libro sono descritte le modalità con cui durante le ore di lezione, di laboratorio e di tirocinio si è cercato di stimolare la riflessione degli studenti e di aumentare la loro consapevolezza circa i processi attivati nell’apprendimento, le motivazioni sottostanti, le situazioni contingenti e gli aspetti più favorevoli allo sviluppo della competenza professionale del maestro. La ricerc…
IPM-recommended insecticides harm beneficial insects through contaminated honeydew
2020
The use of some systemic insecticides has been banned in Europe because they are toxic to beneficial insects when these feed on nectar. A recent study shows that systemic insecticides can also kill beneficial insects when they feed on honeydew. Honeydew is the sugar-rich excretion of hemipterans and is the most abundant carbohydrate source for beneficial insects such as pollinators and biological control agents in agroecosystems. Here, we investigated whether the toxicity of contaminated honeydew depends on i) the hemipteran species that excretes the honeydew; ii) the active ingredient, and iii) the beneficial insect that feeds on it. HPLC-MS/MS analyses demonstrated that the systemic insec…
Preclinical immunomodulation by the probiotic Bifidobacterium breve M-16V in early life
2016
This study aimed to investigate the effect of supplementation with the probiotic Bifidobacterium breve M-16V on the maturation of the intestinal and circulating immune system during suckling. In order to achieve this purpose, neonatal Lewis rats were supplemented with the probiotic strain from the 6th to the 18th day of life. The animals were weighed during the study, and faecal samples were obtained and evaluated daily. On day 19, rats were euthanized and intestinal wash samples, mesenteric lymph node (MLN) cells, splenocytes and intraepithelial lymphocytes (IEL) were obtained. The probiotic supplementation in early life did not modify the growth curve and did not enhance the systemic immu…
Nei luoghi dell'accoglienza. Progetti per Lampedusa e Palermo
2014
Il libro raccoglie gli esiti della ricerca e della didattica dei Laboratori di Progettazione architettonica del terzo anno, svolti presso il corso di Laurea Magistrale in Architettura LM4 della Scuola Politecnica dell’Università degli Studi di Palermo, sul tema dell’accoglienza a Lampedusa e a Palermo. L’obiettivo è quello di presentare la composita esperienza di progetto e di ricerca prodotta intorno all’argomento e nello stesso tempo attivare un confronto sul paesaggio e sugli spazi urbani della città. Il libro cerca di sviluppare un percorso di ricognizione e di conoscenza attraverso l’elaborazione di progetti didattici in grado di produrre idee per la città e il territorio. The book con…
