    Among the interventions recently developed to enhance Executive Functions (EFs) in preschoolers, Quincey Quokka’s Quest (QQQ) is an illustrated book proposing EF activities embedded within a shared reading framework (Howard et al., 2017). In the present study, the Italian version of QQQ (QQQIT) was tested in 20 typical developing 4–5 year old children. Standardized tests were used to assess EFs pre- and post- intervention. QQQIT was conducted once a week for 8 weeks in small groups. A positive trend was registered in QQQIT performances from the first to the last sessions and a significant improvement, in comparison to the control condition, was obtained in the Color and Form Game test. These results, supporting the feasibility of the QQQIT intervention and its efficacy in increasing shifting abilities, confirm the usefulness of ecological interventions to empower specific EF components in preschool contexts

    Bioreduction of substituted a-tetralones promoted by Daucus carota root

    Get PDF
    The bioreduction of a series of substituted a-tetralones, carried out using Daucus carota root (carrot), afforded the corresponding homochiral a-tetralols in variable conversions (9 to 90%) and excellent enantiomeric excesses. Two of the assayed a-tetralones were resistant to the bioreduction conditions. The absolute configurations of four a-tetralols were assigned as being (S), by comparison to the (S)-enantiomers obtained by kinetic resolution promoted by CALB-catalysed acetylation. Additionally, the new 5-methoxy-6-methyl-1-tetralone was synthesized in seven steps from 3-methylsalicylic acid.FAPESPCoordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES)CNP

    Executive functions in children with specific learning disorders: Shedding light on a complex profile through teleassessment

    Get PDF
    Executive Functions (EFs) are high-order cognitive processes relevant to learning and adaptation and frequently impaired in children with specific learning disorders (SLDs). This study aimed to investigate EFs in children with SLD and explore the role of specific EF-related subprocesses, such as stimuli processing and processing speed. Fifty-seven SLD and 114 typically developing (TD) children, matched for gender and age, completed four tasks measuring response inhibition, interference control, shifting, and updating on a web-based teleassessment platform. The results show that SLD children performed lower in all EF tasks than TD children, regardless of stimulus type and condition. Mediation analyses suggested that differences between the SLD and TD groups are mediated by EF-related subprocesses, offering an interpretative model of EF deficits in children with SLD

    Integrated didactics: an example of a curriculum model enhancing knowledge crossing

    In this paper, we introduce an innovative course in the Portuguese Context, the Master's Course in “Integrated Didactics in Mother Tongue, Maths, Natural and Social Sciences”, taking place at the Lisbon School of Education and discussing in particular the results of the evaluation made by the students who attended the Curricular Unit - Integrated Didactics (CU-ID). This course was designed for in-service teachers of the first six years of schooling and intends to improve connections between different curriculum areas. In this paper, we start to present a few general ideas about curriculum development; to discuss the concept of integration; to present the principles and objectives of the course created as well as its structure; to describe the methodology used in the evaluation process of the above mentioned CU-ID. The results allow us to state that the students recognized, as positive features of the CU-ID, the presence in all sessions of two teachers simultaneously from different scientific areas, as well as invitations issued to specialists on the subject of integration and to other teachers that already promote forms of integration in schools. As negative features, students noted a lack of integrated purpose, applying simultaneously the four scientific areas of the course, and also indicated the need to be familiar with more models of integrated education. Consequently, the suggestions for improvement derived from these negative features. The students also considered that their evaluation process was correct, due to the fact that it was focused on the design of an integrated project for one of the school years already mentioned

    Gross morphometry of the heart of the Common marmoset

      The Callithrix jacchus is a Brazilian endemic species that has been widely used asan experimental model in biomedical research. Anatomical data are necessary to support experimental studies with this species. Eleven hearts of C. jacchus from the German Primate Centre (DPZ) have been studied in order to characterize their gross morphometry and compare them with other animal models and human. Biometric data were also obtained. The mean values for morphometry of the hearts did not show any significant difference between male and female. The relative heart weight was similar to human, bovine and equine species. Considering those aspects, the C. jacchus could be used as non-human primate experimental modelfor biomedical studies on heart.

    Nosocomial diarrhoea in adult medical patients: the role of Clostridium difficile in a North Italian acute care teaching hospital

    Background. The number of patients with severe Clostrid- ium difficile-associated diarrhoea (CDAD) increases. Health care facilities are requested to establish rates of nosocomially acquired CDAD (N-CDAD) to understand the impact of control or prevention measures, and the burden of N-CDAD on health care resources. Objective. Aim of the single-center surveillance project was to establish local prevalence rates of N-CDAD in adult acute care medical patients. Methods. For a period of at least one year, all diarrhoeal stools from inpatients of a general internal medicine ward were tested for Clostridium difficile toxin A. Case record files were retrospectively analysed and questionnaires were completed for patients with positive stool assays who met the case definitions. Results and discussion. During the surveillance period, 2,610 medical patients had been acutely hospitalized. Stools had been submitted to the hospital laboratory from 163 patients (6.2%) because of diarrhoea and were screened for Clostridium difficile cytotoxin. Complete data sets were available for analysis from 150 patients. Of 137 identified potential cases, 77 (56.2%) met the case definitions for nosocomial diarrhoea. Thirteen of the patients with nosocomial diarrhoea (16.9%) were detected positive by the Clostridium difficile toxin A assay. The overall prevalence of N-CDAD among inpatients was 8.7 cases/100 diarrhoeal stools. The mean number of N-CDAD cases was 62.3 cases/100,000 patient days and 5 cases/1,000 patient admissions. The mean age of N-CDAD patients was 79.4 years (range 71 to 92). All patients were given broad-spectrum antibiotics before acute diarrhoea developed. Four patients died for reasons not directly related to N-CDAD which confirms increased disease severity as an important risk factor . Conclusions. This single-center surveillance project, which established N-CDAD rates at frequencies currently reported from international surveys, is useful as benchmark and will help in understanding patterns and impact of N-CDAD at the regional level

    Atrioventricular valve complex of 30 Jafarabadi water buffaloes, adult males were studied in this research with no heart diseases. The animals were obtained from a slaughterhouse in Brazilian State of Parana. The hearts were opened at the third portion affording access to the valve complex. The complexes had its area, number and type of tendinous cords submitted to analysis. The results showed that the complex is composed by two cusps and four accessory cusps, two or three papillary muscles in which 10-25 tendinous cords fix on the cusps that face the ventricle wall. The total area of the complex was on average 38.56cm², with a minimum of 24.96cm² and a maximum of 55.54cm². Statistically, no relation between the number of cords and the cusps' area where they are inserted or with the number of papillary muscle where they originated from was observed.Foram estudados os complexos valvares atrioventricular esquerdo de 30 búfalos da raça Jafarabadi, machos e adultos, sem alterações cardíacas, provenientes de abatedouros do Estado do Paraná.
