    To explore the relationship between memory and early school performance, we used graph theory to investigate memory reports from 76 children aged 6–8 years. The reports comprised autobiographical memories of events days to years past, and memories of novel images reported immediately after encoding. We also measured intelligence quotient (IQ) and theory of mind (ToM). Reading and Mathematics were assessed before classes began (December 2013), around the time of report collection (June 2014), and at the end of the academic year (December 2014). IQ and ToM correlated positively with word diversity and word-to-word connectivity, and negatively with word recurrence. Connectivity correlated positively with Reading in June 2014 as well as December 2014, even after adjusting for IQ and ToM. To our knowledge, this is the first study demonstrating a link between the structure of children’s memories and their cognitive or academic performance.To explore the relationship between memory and early school performance, we used graph theory to investigate memory reports from 76 children aged 6–8 years.

    Changes in the midpalatal and pterygopalatine sutures induced by micro-implant-supported skeletal expander, analyzed with a novel 3D method based on CBCT imaging

    Abstract Background Mini-implant-assisted rapid palatal expansion (MARPE) appliances have been developed with the aim to enhance the orthopedic effect induced by rapid maxillary expansion (RME). Maxillary Skeletal Expander (MSE) is a particular type of MARPE appliance characterized by the presence of four mini-implants positioned in the posterior part of the palate with bi-cortical engagement. The aim of the present study is to evaluate the MSE effects on the midpalatal and pterygopalatine sutures in late adolescents, using high-resolution CBCT. Specific aims are to define the magnitude and sagittal parallelism of midpalatal suture opening, to measure the extent of transverse asymmetry of split, and to illustrate the possibility of splitting the pterygopalatine suture. Methods Fifteen subjects (mean age of 17.2 years; range, 13.9–26.2 years) were treated with MSE. Pre- and post-treatment CBCT exams were taken and superimposed. A novel methodology based on three new reference planes was utilized to analyze the sutural changes. Parameters were compared from pre- to post-treatment and between genders non-parametrically using the Wilcoxon sign rank test. For the frequency of openings in the lower part of the pterygopalatine suture, the Fisher’s exact test was used. Results Regarding the magnitude of midpalatal suture opening, the split at anterior nasal spine (ANS) and at posterior nasal spine (PNS) was 4.8 and 4.3 mm, respectively. The amount of split at PNS was 90% of that at ANS, showing that the opening of the midpalatal suture was almost perfectly parallel antero-posteriorly. On average, one half of the anterior nasal spine (ANS) moved more than the contralateral one by 1.1 mm. Openings between the lateral and medial plates of the pterygoid process were detectable in 53% of the sutures (P < 0.05). No significant differences were found in the magnitude and frequency of suture opening between males and females. Correlation between age and suture opening was negligible (R 2 range, 0.3–4.2%). Conclusions Midpalatal suture was successfully split by MSE in late adolescents, and the opening was almost perfectly parallel in a sagittal direction. Regarding the extent of transverse asymmetry of the split, on average one half of ANS moved more than the contralateral one by 1.1 mm. Pterygopalatine suture was split in its lower region by MSE, as the pyramidal process was pulled out from the pterygoid process. Patient gender and age had a negligible influence on suture opening for the age group considered in the study

    Qualidade Composicional do Leite de um rebanho Jersey no Sul do Rio Grande do Sul

    A qualidade do leite apresenta cada vez mais importância para o setor lácteo nacional, visando o mercado consumidor interno e externo. Conhecer a qualidade composicional do leite produzido pelo rebanho e os fatores que o influenciam pode auxiliar o produtor a obter maior remuneração pela matéria prima. O objetivo deste trabalho é avaliar a qualidade composicional e a sazonalidade do leite de um rebanho Jersey da Região Sul do Rio Grande do Sul. O estudo foi realizado no período de Janeiro a Dezembro de 2014, em um rebanho da Embrapa Clima Temperado da Estação Experimental Terras Baixas do Capão do Leão - RS. Foram utilizados os dados do controle leiteiro mensal do rebanho. Os teores médios dos componentes foram: Gordura 4,58%, Proteína Bruta 3,29%, Lactose 4,47%, Sólidos Totais 13,31% e sólidos desengordurados 8,73%. A qualidade do leite do rebanho avaliado apresentou médias adequadas aos padrões estabelecidos pela Instrução Normativa 62. As maiores variações ocorreram nos teores de gordura possivelmente devido ao estágio de lactação do rebanho

    Epidemiological situation and risk Factors to Infectious Diseases in Dairy Cattle Located in Different Mesoregions of the State of Rio Grande do Sul, Brazil, 2016/2017.

    The aim of this study was to describe the epidemiology of infectious bovine rhinotracheitis (IBR), bovine viral diarrhea (BVD), neosporosis (NEO) and leptospirosis (LEP) from the perspective of the impact these diseases have to cause reproductive problems in dairy cattle herds located in different mesoregions of Rio Grande do Sul State. The herds analysed belong to two cooperatives and an association of producers. The seroprevalences of IBR, BVD, NEO and LEP ranged from 54.4 to 60.3%, 30.0 to 42.5%, 21.8 to 35.0% and 15.8 to 27.5%, respectively. The seroprevalences of IBR show a homogeneous distribution of the disease according to the mesoregions. Nevertheless, IBR was associated with estrus recurrence and abortion in herds located in the northeast and northwest mesoregions. BVD was associated with rearing of estrus in herds located in the southeast, southwest, northeast and northwest mesoregions. NEO was associated with cases of abortion in the herds located in the northeast and northwest mesoregions. LEP was associated with miscarriages in herds located in the northwest mesoregion. It was found that the epidemiological character of the disease cases were distinct in the different mesoregions. In this way, the priorities in the control and prevention programs of these diseases are different between the mesoregions, cooperatives and association of producers. Despite that fact, common control procedures were found amongst the disease cases studied; each one of them has its peculiarity in relation to the epidemiology and consequently control and preventio

    Reading and writing habits compensate for aging effects in speech connectedness

    We investigate the association of short- and long-range recurrences (speech connectedness) with age, education, and reading and writing habits (RWH) in typical aging using an oral narrative production task. Oral narrative transcriptions were represented as word-graphs to measure short- and long-range recurrences. Speech connectedness was explained by the combination of age, education, and RWH, and the strength of RWH’s coefficient reflects the aging effect
