Future teachers must be competent in creating educational settings, which provide tools to their students future they can develop a conscious mind, able to interpret their experiences, to make decisions and imagine innovative solutions to help you participate autonomously and responsible in society. This requires an educational system that allows them to integrate the subjective into a broader spatial and temporal context. La patrimonializatión of “Cultural artefacts” and oral history, the basis of which, are found in the active mind and links both the personal and the group experience, don’t only serve as a catalyst to achieving this goal, but rather, they facilitate the implementation of established practice in infant education. To gain this experience we offer the opportunity for students of their degree in Infant Education in the Public University of Navarre, training within the framework of social didactics, allowing students to learn about established practice from iconic, materials and oral sources in the Archive of Intangible Cultural Heritage of Navarra. The vidences points to their effectiveness and presented in a work in progress.

Treatment of emerging RNA viruses is hampered by the high mutation and replication rates that enable these viruses to operate as a quasispecies. Declining honey bee populations have been attributed to the ectoparasitic mite Varroa destructor and its affiliation with Deformed Wing Virus (DWV). In the current study we use next-generation sequencing to investigate the DWV quasispecies in an apiary known to suffer from overwintering colony losses. We show that the DWV species complex is made up of three master variants. Our results indicate that a new DWV Type C variant is distinct from the previously described types A and B, but together they form a distinct clade compared with other members of the Iflaviridae. The molecular clock estimation predicts that Type C diverged from the other variants ~319 years ago. The discovery of a new master variant of DWV has important implications for the positive identification of the true pathogen within global honey bee populations.

Introdução: Com uma consciencialização cada vez maior das populações para a preservação dos dentes naturais, a Endodontia tem assumido uma importância crescente, tendo por objectivo principal a manutenção de dentes funcionais, sem prejudicar a saúde dos pacientes. Estes devem beneficiar de um tratamento segundo o “standard of care”, proporcionado por profissionais competentes. Vários estudos demonstram que a Endodontia é considerada uma área difícil e stressante para os estudantes, exibindo um sentimento de menor confiança na prática clínica, sobretudo no que diz respeito a procedimentos mais complexos, nomeadamente, no tratamento de dentes posteriores. Em 2010, na tentativa de homogeneizar as competências adquiridas pelos Médicos Dentistas (MD), a Associação para a Educação Dentária Europeia (AEDE) definiu critérios para a sua formação pré-graduada, indicando que o MD recém-graduado deve ter adquirido competências e capacidades técnicas que lhe permita começar a sua prática clínica de forma independente. Objectivos: Analisar os conhecimentos adquiridos e as dificuldades sentidas na área da Endodontia pelos alunos do 4º e 5º anos do Mestrado Integrado em Medicina Dentária da Faculdade de Ciências de Saúde (FCS) da Universidade Fernando Pessoa (UFP), fazendo, igualmente, uma abordagem ao ensino ministrado na área da Endodontia face aos resultados obtidos. Materiais e Métodos: Este trabalho está dividido em duas partes: revisão bibliográfica e investigação científica. A revisão bibliográfica do tema engloba o ensino graduado em Medicina Dentária, o uso de isolamento absoluto (IA) na prática clínica de Endodontia, a instrumentação manual versus rotatória, a influência no sucesso do tratamento endodôntico (TE) da sua execução por estudantes do 4º e 5º ano, as Guidelines para o TE e o ensino de Endodontia na UFP. A pesquisa bibliográfica foi efectuada através da base de dados PubMed, tendo sido utilizadas, em diferentes combinações, as seguintes palavras-chave: ”Endodontics”, “teaching”; “pre-clinical”; “undergraduate”; “Clinical”; “treatment” e “Europe”. O trabalho de investigação consistiu na elaboração, aprovação pela Comissão de Ética da UFP e posterior aplicação de um questionário destinado aos alunos do 4º e 5º ano do Mestrado Integrado em Medicina Dentária da FCS-UFP. A população estimada de alunos do 4º ano foi de 190 alunos e a de 5º ano de 150 alunos, o que perfaz um total de 340 alunos. Dos inquéritos respondidos, apenas foram considerados 338, uma vez que dois foram anulados pois continham respostas inválidas. Resultados: A “condição socioeconómica do paciente” foi considerada a causa menos relevante para avaliar um caso endodôntico, tendo sido apontada por 34,3% dos alunos. Assinala-se que 92% dos alunos de 4º ano e 93,3% dos alunos de 5º ano consideram que os molares superiores são os dentes mais difíceis de tratar, sendo a visibilidade uma das principais razões para esta opinião. O grau de dificuldade para a colocação do IA é definido como “Elevado” para a maioria dos alunos de 4º ano. A maior parte dos alunos de 5º ano considera que o grau de dificuldade para a “Determinação do tipo de reconstrução/prótese fixa mais indicada” é “Elevado”. O passo do TE onde os alunos do 4º ano se sentem mais confiantes é no “Diagnóstico de cárie”, sendo que os alunos do 5º ano se sentem mais confiantes ao realizar o “TE em dentes com 1 ou 2 canais”. O “Conteúdo leccionado nas aulas teóricas” foi considerado o principal aspecto positivo do ensino endodôntico. Por outro lado, o “Número de actos clínicos realizados” foi considerado o principal aspecto negativo, tanto para alunos de 4º como de 5º ano. Em ambos os anos, os principais pontos que os alunos acham que devem ser melhorados são o “Número de pacientes nas aulas clínicas” e a “Aprendizagem da técnica de instrumentação mecanizada/obturação termoplástica”. As principais preocupações referidas, tanto por alunos de 4º como de 5º anos, foram a “Insegurança na prática clínica” e a “Dificuldade em encontrar ofertas profissionais”. Relativamente à qualidade dos seus TE existe um número significativo de alunos do 5º ano que já se auto-avaliam como “Bons” (33,6%), por comparação com os do 4º ano (21,2%), sendo a auto-avaliação de “Razoável” dominante em ambos os anos de formação. Conclusões: Conclui-se que na disciplina de Endodontia na FCS-UFP, são seguidas as Guidelines da European Society of Endodontology (ESE), sendo que estas indicam o protocolo mais correcto a seguir durante o Tratamento Endodôntico Não-Cirúrgico (TENC). Contudo, o reduzido número de actos clínicos e a consequente falta de prática faz com que os alunos se sintam pouco confiantes ao iniciar a sua actividade profissional.

Portugal, in particular, and Europe in general are paradigms of diversity in unity and of the need for intercultural mediation and social intervention policies enabling the reception, hospitality, respect for others and their training in a more inclusive society. From a research and sociological and anthropological level of knowledge, the ESECS-IPLeiria invested, in 2013, on a Master program in Intercultural Mediation and Social Intervention that is a unique example in Portugal. In this paper, in addition to present the Master’s curriculum, we invest in the distinction between preventive mediation, transformative and social empowerment, rather than focusing on solving, typical of conflict resolution, based on the questionable pillar of neutrality and impartiality.

Pyrimidine-5'-nucleotidase type I (P5'NI) deficiency is an autosomal recessive condition that causes nonspherocytic hemolytic anemia, characterized by marked basophilic stippling and pyrimidine nucleotide accumulation in erythrocytes. We herein present two African descendant patients, father and daughter, with P5'N deficiency, both born from first cousins. Investigation of the promoter polymorphism of the uridine diphospho glucuronosyl transferase 1A (UGT1A) gene revealed that the father was homozygous for the allele (TA7) and the daughter heterozygous (TA6/TA7). P5'NI gene (NT5C3) gene sequencing revealed a further change in homozygosity at amino acid position 56 (p.R56G), located in a highly conserved region. Both patients developed gallstones; however the father, who had undergone surgery for the removal of stones, had extremely severe intrahepatic cholestasis and, liver biopsy revealed fibrosis and siderosis grade III, leading us to believe that the homozygosity of the UGT1A polymorphism was responsible for the more severe clinical features in the father. Moreover, our results show how the clinical expression of hemolytic anemia is influenced by epistatic factors and we describe a new mutation in the P5'N gene associated with enzyme deficiency, iron overload, and severe gallstone formation. To our knowledge, this is the first description of P5'N deficiency in South Americans.

We describe herein a general method for the controlled Heck arylation of allylated malonates. Both electron-rich and electron-poor aryldiazonium salts were readily employed as the aryl-transfer agents in good yields and in high chemo-, regio-, and stereoselectivity without formation of decarboxylated byproducts. Reaction monitoring via ESI-MS was used to support the formation of chelated Pd species through the catalytic cycle. Additionally, some Heck adducts were successfully used in the total synthesis of pharmacologically active γ-lactones.

Excessive occlusal surface wear can result in occlusal disharmony, functional and esthetic impairment. As a therapeutic approach, conventional single crowns have been proposed, but this kind of treatment is complex, highly invasive and expensive. This case report describes the clinical outcomes of an alternative minimally invasive treatment based on direct adhesive-pin retained restorations. A 64-year-old woman with severely worn dentition, eating problems related to missing teeth and generalized tooth hypersensitivity was referred for treatment. Proper treatment planning based on the diagnostic wax-up simulation was used to guide the reconstruction of maxillary anterior teeth with direct composite resin over self-threading dentin pins. As the mandibular remaining teeth were extremely worn, a tooth-supported overdenture was installed. A stabilization splint was also used to protect the restorations. This treatment was a less expensive alternative to full-mouth rehabilitation with positive esthetic and functional outcomes after 1.5 years of follow-up.

The goal of this cross-sectional observational study was to quantify the pattern-shift visual evoked potentials (VEP) and the thickness as well as the volume of retinal layers using optical coherence tomography (OCT) across a cohort of Parkinson's disease (PD) patients and age-matched controls. Forty-three PD patients and 38 controls were enrolled. All participants underwent a detailed neurological and ophthalmologic evaluation. Idiopathic PD cases were included. Cases with glaucoma or increased intra-ocular pressure were excluded. Patients were assessed by VEP and high-resolution Fourier-domain OCT, which quantified the inner and outer thicknesses of the retinal layers. VEP latencies and the thicknesses of the retinal layers were the main outcome measures. The mean age, with standard deviation (SD), of the PD patients and controls were 63.1 (7.5) and 62.4 (7.2) years, respectively. The patients were predominantly in the initial Hoehn-Yahr (HY) disease stages (34.8% in stage 1 or 1.5, and 55.8 % in stage 2). The VEP latencies and the thicknesses as well as the volumes of the retinal inner and outer layers of the groups were similar. A negative correlation between the retinal thickness and the age was noted in both groups. The thickness of the retinal nerve fibre layer (RNFL) was 102.7 μm in PD patients vs. 104.2 μm in controls. The thicknesses of retinal layers, VEP, and RNFL of PD patients were similar to those of the controls. Despite the use of a representative cohort of PD patients and high-resolution OCT in this study, further studies are required to establish the validity of using OCT and VEP measurements as the anatomic and functional biomarkers for the evaluation of retinal and visual pathways in PD patients.

Abstract The aim of this study was to evaluate three transfer techniques used to obtain working casts of implant-supported prostheses through the marginal misfit and strain induced to metallic framework. Thirty working casts were obtained from a metallic master cast, each one containing two implant analogues simulating a clinical situation of three-unit implant-supported fixed prostheses, according to the following transfer impression techniques: Group A, squared transfers splinted with dental floss and acrylic resin, sectioned and re-splinted; Group B, squared transfers splinted with dental floss and bis-acrylic resin; and Group N, squared transfers not splinted. A metallic framework was made for marginal misfit and strain measurements from the metallic master cast. The misfit between metallic framework and the working casts was evaluated with an optical microscope following the single-screw test protocol. In the same conditions, the strain was evaluated using strain gauges placed on the metallic framework. The data was submitted to one-way ANOVA followed by the Tukey's test (α=5%). For both marginal misfit and strain, there were statistically significant differences between Groups A and N (p<0.01) and Groups B and N (p<0.01), with greater values for the Group N. According to the Pearson's test, there was a positive correlation between the variables misfit and strain (r=0.5642). The results of this study showed that the impression techniques with splinted transfers promoted better accuracy than non-splinted one, regardless of the splinting material utilized.
