Effect of seasonality on physico-chemical and microbiological properties of nicastrese milk and artisanal cheese
2021
ABSTRACT Nicastrese is an indigenous Italian goat breed reared in the Calabria region under semi-extensive practices. From January to June, the milk yield of 400 multiparous Nicastrese goats was evaluated. In addition, tank milk and ripened cheese samples were subjected to physico-chemical and microbiological analyses with the aim to assess the effect of the seasonality on quality parameters. The volatile organic compounds profile of the ripened Nicastrese cheese samples was evaluated. Results showed that the seasonality had a significant effect on milk fat, lactose, urea, citric acid contents and acidity. Microbiological analysis of tank milk samples revealed variability among the differen…
Isolation and characterization of microsatellite markers in the liver fluke (Fasciola hepatica)
2004
PRIMER NOTE; International audience; Six microsatellite markers were isolated from Fasciola hepatica, a re-emerging parasite that causes important veterinary and public health problems. In a sample of 52 liver flukes from a region of hyperendemicity (Bolivian Altiplano), five microsatellite were polymorphic. Our results showed that liver flukes present important genetic variability, suggesting a preferential outcrossing reproduction mode for this hermaphroditic parasite.
Patterns of word reading skill, interest and self-concept of ability
2016
AbstractThe majority of previous research on academic skills, self-concept of ability and interest has deployed the variable-oriented approach and focused on self-concept, or ability, or interest only. This study examined the patterns and dynamics of pattern change in Finnish children’s word reading skill, self-concept of ability and interest from kindergarten to Grade 2. Six groups of children were identified by using the I-states as objects analysis (ISOA) procedure: (a) low skills, negative self-concept but high interest; (b) high skills but low interest; (c) average; (d) high skills, positive self-concept and high interest; (e) low skills, negative self-concept and low interest; and (f)…
Brain Opioid Activity and Oxidative Injury: Different Molecular Scenarios Connecting Celiac Disease and Autistic Spectrum Disorder
2020
Celiac Disease (CD) is an immune-mediated disease triggered by the ingestion of wheat gliadin and related prolamins from other cereals, such as barley and rye. Immunity against these cereal-derived proteins is mediated by pro-inflammatory cytokines produced by both innate and adaptive system response in individuals unable to adequately digest them. Peptides generated in this condition are absorbed across the gut barrier, which in these patients is characterized by the deregulation of its permeability. Here, we discuss a possible correlation between CD and Autistic Spectrum Disorder (ASD) pathogenesis. ASD can be induced by an excessive and inappropriate brain opioid activity during the neon…
Greater mitochondrial energy production provides resistance to ocean acidification in "winning" hermatypic corals
2021
Coral communities around the world are projected to be negatively affected by ocean acidification. Not all coral species will respond in the same manner to rising CO2 levels. Evidence from naturally acidified areas such as CO2 seeps have shown that although a few species are resistant to elevated CO2, most lack sufficient resistance resulting in their decline. This has led to the simple grouping of coral species into “winners” and “losers,” but the physiological traits supporting this ecological assessment are yet to be fully understood. Here using CO2 seeps, in two biogeographically distinct regions, we investigated whether physiological traits related to energy production [mitochondrial e…
In pursuit of beginning teachers'competence in promoting reading motivation: a mixed-methods study into the impact of a contunuing professional devel…
2020
As teachers’ reading motivation and self-efficacy for promoting reading motivation can be considered vital for their reading-oriented promotive teaching practices and students’ reading motivation, this study evaluated the impact of a year-long CPD program for beginning primary school teachers. A convergent parallel mixed-methods design with repeated measures was established, including a comparison and two CPD conditions (group vs. individually-oriented). Based on the quantitative results only no clear impact of and differences between the conditions could be observed. The qualitative analysis, however, showed growth in teachers’ reading motivation and self-efficacy at a different pace and l…
MOTIVACIÓN Y ESTILO ATRIBUCIONAL SOBRE EL RENDIMIENTO ACADÉMICO EN EDUCACIÓN INFANTIL
2016
El presente trabajo tiene como objetivo examinar el poder predictivo de variables del sistema motivacional sobre las habilidades iniciales de lectura y matemáticas en una muestra de niños de Educación Infantil. Participaron 209 preescolares (5-6 años) y sus maestros. Se evaluaron las habilidades matemáticas de conteo, conocimiento de los números, cálculo y resolución de problemas. Para determinar el rendimiento en lectura se administraron tareas de identificación de letras y de lectura de palabras. Respecto al sistema motivacional, se analizaron las variables de competencia-motivación, atención-persistencia y actitud hacia el aprendizaje, así como las dimensiones de internalidad, globalida…
Standardisation of methods for assessing mould germination: a workshop report.
2006
International audience; The first workshop on predictive mycology was held in Marseille, France, 2–4 February 2005 under the auspices of the French Microbiological Society. The purpose of the workshop was to list the different techniques and definitions used by scientists for assessing mould germination and to evaluate the influence of the different techniques on the experimental results. Recommendations were made when a large consensus was obtained. In order to facilitate the study of germination, alternative methods to microscopic examination were examined.
Influencia del sesgo de género en el diagnóstico de trastorno de espectro autista: una revisión
2018
espanolLa prevalencia del trastorno de espectro autista (TEA) se ha incrementado en los ultimos anos, en parte debido a las mejoras de los metodos de deteccion y en parte a las modi- ficaciones en la definicion que se han ido incorporando a los manuales diagnosticos. Este incremento ha provocado que el indice de prevalencia por genero sea en la actualidad de un 1,4/1, segun algunos autores, o hasta de un 15,7/1 segun otros, con un numero muy superior de varones que reciben el diagnostico en comparacion con el numero de mujeres que lo reciben. Las distintas explicaciones que se han dado a esta cuestion apuntan a unas determinadas diferencias de genero en las manifestaciones sintomaticas del …
Sustainability Development in Mathematics Education : A Case Study of What Kind of Meanings Do Prospective Class Teachers Find for the Mathematical S…
2019
In this article, our focus is on sustainable development in mathematics education from the point of view of teacher training. The aim was to develop prospective teachers’ content knowledge and pedagogical content knowledge of school mathematics. As a case study, we chose the mathematical symbol “a/b”, and examined how prospective class teachers in Finland connect it to the concepts of fraction, ratio, division, rational number or probability. Mathematics textbooks often have a central role in lessons, and they affect strongly how pupils understand concepts and the relationships between them. We chose languaging as a multi-semiotic approach to interpreting what kind of meanings the prospecti…
