    "Limited attention has been given to the presence of fungi in the aquatic environment when compared to other microorganisms such as bacteria and virus. Our previous research showed that fungi occur widely in drinking water sources and described many fungi species that have not been previously reported in the aquatic environment. Moreover, many filamentous fungi species present in water were found to be able to grow at high temperatures and have conidia measurements lower than 5 ¬Ķm, being therefore considered as potential pathogenic species to humans and animals.

    Among the different nuts grown worldwide, hazelnut (Corylus avellana L.) is considered one of the most popular and consumed. Hazelnut is mainly used by the food industry in chocolates, cakes and desserts, with only a small part of the world’s produc"on being consumed as table hazelnut. Hazelnut is considered to be a highly nutri"ous food, providing macronutrients (fat, protein and carbohydrates), micronutrients (vitamins and minerals) and several bioac"ve phytochemicals, including phenolic acids, flavonoids, tannins and phytosterols, among others. Despite presen"ng a high content in fat, hazelnut lipids mainly include monounsaturated fa$y acids (MUFA), which have been associated with beneficial health effects, par"cularly regarding the cardiovascular system. Moreover, different interes"ng proper"es, such as an"oxidant, an"-inflammatory, an"-prolifera"ve and hipocholesterolemic ac"vi"es have been ascribed to several micronutrients and phytochemicals present in hazelnuts. To date, some studies have shown that the consump"on of hazelnuts can have a beneficial effect on health, namely by reducing the risk of cardiovascular diseases. Therefore, its inclusion has been recommended as part of a healthy-diet.Os autores agradecem o financiamento da Fundação para a Ciência e a Tecnologia (FCT) através do projeto UID/ QUI/50006/2013 - POCI/01/0145/FEDER/007265 com apoio financeiro da FCT/MEC através de fundos nacionais e cofinanciamento FEDER.info:eu-repo/semantics/publishedVersio

    For a healthy pregnancy, it is recommended to create healthy lifestyles. Daily physical activity and a proper and balanced diet are considered essential for the well-being of both pregnant and baby. In this sense, appears the project " Sporty Belly ", which consists in development a program of support and encouragement for pregnant women from Guimar√£es, through exercise classes and moments of sharing information about most appropriate living habits in this phase. In this paper we aim to present the exercise program that is being carried out and characterize the initial profile of the participants involved in this project , namely the level of physical activity when started the program , BMI before pregnancy and smoking habits. The exercise program is held three times a week, one of which on the aquatic environment and can be attended at any gestational age provided there are no medical or obstetrical contraindications to physical exercise. The classes consist of performing aerobic exercise, strength, balance and stretching. Participated in this intervention program 102 pregnant women aged between 24 and 42 years old, with a mean (standard deviation) 31.91 (3.65). ). Gestational age at begining of the program is 17.22 (5.45) weeks. Before pregnancy n (%) 19 (19.4) were overweight and obese, 71 (69.6) practiced regular exercise before pregnancy and only 6 (5.9) have smoking habits. As regards the level of physical activity, the mean (SD) of the weekly energy expenditure was 159.76 Met- h.wk -1 (89.27), and most is spent in sedentary activities or light intensity (71, 9%).CIEC ‚Äď Research Centre on Child Studies, IE, UMinho (FCT R&D unit 317), Portugal; National Funds through the FCT (Foundation for Science and Technology) and co-financed by European Regional Development Funds (FEDER) through the Competitiveness and Internationalization Operational Program (POCI) through CIEC (Research Centre on Child Studies, of the University of Minho) with the reference POCI-01-0145-FEDER-00756

    A disciplina de Educa√ß√£o F√≠sica tem um forte efeito socializador entre os jovens e dever√° ter um papel primordial no combate aos problemas de viol√™ncia, indisciplina e bullying que preocupam a escola atual. Esta investiga√ß√£o pretende analisar as interinflu√™ncias entre a Educa√ß√£o F√≠sica e o comportamento bullying e compreender em que medida este problema prejudica as finalidades relacionais, humanistas e √©ticas desta disciplina. Estudo anal√≠tico de delineamento transversal realizado numa amostra de 1818 alunos de escolas portuguesas, com uma m√©dia de idades de 12,8 anos. Conclu√≠mos que as atitudes e opini√Ķes dos alunos com experi√™ncias de bullying, em rela√ß√£o √† participa√ß√£o na aula de Educa√ß√£o F√≠sica, s√£o distintas das dos restantes alunos: os alunos que assumiram ter agredido/bullied, manifestam maior concord√Ęncia com opini√Ķes prepotentes e injustas do que os alunos que n√£o agrediram/bullied e os alunos que foram v√≠timas de bullying sentem mais dificuldades e constrangimentos na sua participa√ß√£o na aula de EF do que os colegas que nunca foram vitimados; comprovou-se igualmente que os alunos com experi√™ncias de bullying (seja vitimiza√ß√£o ou agress√£o) t√™m expectativas mais reduzidas em rela√ß√£o √†s aprendizagens nesta disciplina. Finalmente confirmou-se que um aproveitamento insatisfat√≥rio nesta disciplina constituiu um significativo fator de risco relativamente √† probabilidade de um aluno ser v√≠tima de bullying pelos seus pares.The discipline of Physical Education has a strong socializing effect on young people and should have a major role in the struggle against violence, indiscipline and bullying related problems that concern today‚Äôs school community. This research aims to analyse the interaction between Physical Education and bullying behaviour and to understand to what extent this problem undermines the relational, humanistic and ethical purposes of this school subject. Cross-sectional analytical study conducted in a sample of 1818 students from portuguese schools, with a mean age of 12.8 years. We conclude that the attitudes and opinions of students with experiences of bullying, relatively to participation in physical education classes, are distinct from other students‚Äô: students who have bullied someone show better agreement with arrogant and unjust opinions than those didn‚Äôt and students who were victims of bullying experience more difficulties and constraints towards their participation in physical education class, than their colleagues who were never victimized; it was also confirmed that students with who have experienced bullying (either victimization or aggression) have lower expectations regarding learning in this course. Lastly it was confirmed that a negative assessment in this discipline was a significant risk factor for a student‚Äôs probability of being bullied by his or her peers.CIEC - Centro de Investiga√ß√£o em Estudos da Crian√ßa, UM (UI 317 da FCT
