Sound production in the Meagre, Argyrosomus regius (Asso, 1801): intraspecific variability associated with size, sex and context

Many fish taxa produce sound in voluntary and in disturbance contexts but information on the full acoustic repertoire is lacking for most species. Yet, this knowledge is critical to enable monitoring fish populations in nature through acoustic monitoring.Portuguese Foundation for Science and Technology: PTDC/BIA-BMA/30517/2017; SFRH/BD/115562/2016; UID/MAR/04292/2019; UID/BIA/00329/2019; PTDC/BIA-BMA/29662/2017.info:eu-repo/semantics/publishedVersio

A importância do recreio escolar na atividade física das crianças

Os benefícios da atividade física em crianças e adolescentes são bem conhecidos e estão bem fundamentados na literatura. Em idade escolar, a manutenção de níveis adequados de atividade física visa sobretudo o crescimento e desenvolvimento saudável e normal, para além da criação de hábitos de atividade física que se irão prolongar ao longo da vida. As escolas são locais com potencial para serem promovidos comportamentos saudáveis. No contexto escolar, o recreio é reconhecidamente um tempo e um espaço importante no âmbito da promoção da atividade física em crianças. Dadas as suas características o recreio apresenta-se como uma excelente oportunidade de acumular atividade física ao longo do dia, além de outros benefícios, nomeadamente de aspetos: sociais (partilha, cooperação, comunicação, resolução de conflitos, auto disciplina, etc.); emocionais (libertação do stress, auto estima, desenvolvimento do carácter, etc.); e cognitivos (criatividade, resolução de problemas e vocabulário, etc.). Resultados de diversos estudos permitem-nos concluir que as crianças beneficiam com intervenções no recreio escolar. Supervisão, encorajamento, pinturas multicolores do espaço de recreio com jogos infantis e imagens coloridas sugestivas, equipamentos móveis de jogo, e aumento do tempo passado no recreio são exemplos bem-sucedidos e com baixos custos de intervenções realizadas com o propósito de aumentar a atividade física diária das crianças. Redesenhar o espaço com pinturas multicolores e alterações estruturais do espaço físico do recreio, é outro tipo de intervenção realizada. O recreio escolar afigura-se como um espaço privilegiado de promoção de hábitos de atividade física nas crianças, não devendo por isso ser negligenciado

Waist circumference and motor coordination in Portuguese school children

Introduction: Children’s motor coordination may affect their activity pattern and thereby influence their body-fatness. The aim of this study was to analyze the relation between motor coordination and waist circumference (WC) levels, in a Portuguese sample of school children aged 8–12 years old. Methods: The sample comprised 402 urban school children (girls- 46.8%), aged 8 to 12 years old (mean 9.6 = ± 0.6 years) from North of Portugal. WC was measured with standardize protocols. Age- and sex-adjusted Z-scores were also computed for WC. Motor coordination levels were assessed with the Ko¨ rperkoordination Test fu¨ r Kinder (KTK) and children were classified according to age-and sex KTK criteria [1]. Results: In motor coordination, 27.1% girls showed disturbance of coordination; 33.5% insufficiencies of coordination; 39.4% normal coordination and 0% good coordination. Corresponding figures for boys were 7.9%; 39.3; 50.9%, and 1.9% respectively (P < 0.001). Linear regression analysis showed that Z-Scores WC were negatively associated with motor coordination (Unstandardized B = -5642 SE:0.706, P < 0.001). Conclusion: Low-motor coordination levels are negatively associated with waist circumference Z-scores. The early identification of children with poor motor coordination is crucial in order to implement and develop health-related behaviors

Waist circumference predicts poor motor coordination in Portuguese school children

Body fatness may influence motor coordination in young children. We aimed to analyze the relation between motor coordination and waist circumference (WC) and to determine the ability of WC to identify children at risk of poor motor coordination based on receiver operating characteristic curve (ROC) analysis, in a sample of Portuguese children. Methods: The sample comprised 738 urban school children (45.8% girls), aged 8 to 12 years (mean 10.2=±1.2 years) from North of Portugal. WC was measured with standardize protocols. Motor coordination levels were assessed with the Körperkoordination Test für Kinder (KTK) and children were classified according to age-and sex KTK criteria. For ROC analysis, subjects were classified in two groups: (i) disturbances and insufficiencies of coordination; (ii) normal and good coordination. Results: Linear regres- sion analysis showed that WC was negatively associated with motor coor- dination (B= - 0.553 SE:0.066, p<0.001 in boys and B= - 0.527 SE:0.084, p<0.001 in girls). ROC analysis showed that WC predicted poor motor coordination (AUC: 0.672; 95%CI: 0.623 to 0.717, p<0.001 for boys; AUC: 0.659; 95%CI: 0.606 to 0.710, p<0.001 for girls) with WC cut-off values of 71 cm for boys and of 66 cm for girls. Conclusions: Waist circumference was associated with poor motor coordination. The early identification of children with high waist circumference may be important to implement and develop health-related behaviours as well as to avoid having poor motor coordination

Citizens in the making: a contribution to children's environmental health education

As ações educativas têm especial papel na conformação do cidadão e na mudança da qualidade de vida e saúde. Apresenta-se o relato de experiência de educação em saúde, realizada no Programa de Saúde da Família por Agentes Comunitários de Saúde, tendo como alvo crianças e como tema o meio ambiente. Os objetivos são: despertar para o sentido do que é ser um cidadão, partindo da noção de direitos e deveres das crianças; convidar as crianças, de forma lúdica e prazerosa, a refletirem sobre a necessidade do cuidado com a saúde do corpo e do meio ambiente; possibilitar o conhecimento e a visualização de alguns agentes causadores de doenças comuns nas crianças da comunidade. A proposta é desenvolvida em três encontros básicos, por meio da apresentação de duas peças de teatro infantil, de um passeio à comunidade com crianças e professores e da improvisação de um laboratório para visualização de animais comuns. Os resultados apontam que pais e professores relatam mudanças de comportamento das crianças com relação ao cuidado com a higiene pessoal e com o meio ambiente, cobrando também dos adultos o mesmo cuidado. O passeio na comunidade com professores e crianças propicia um novo olhar das crianças sobre o seu entorno e, para os novos professores, muitas vezes um primeiro olhar sobre a comunidade. Recomendação: por meio da ação educativa pautada no diálogo, é possível ter uma criança capaz de modificar o meio em que vive, conhecedora de seus direitos e deveres e, sobretudo, um cidadão em formação.Educational activities have a special role in the consolidation of citizenship as well as in promoting changes in the quality of life and health. This paper presents a report on community-based health agents' experiences of environmental health education directed towards children within a Primary Health Care Center's Family Health Strategy. The objectives of this activity are to: develop a notion of children's rights and duties thus fostering awareness of citizenship; invite children, in a pleasant and playful manner, to reflect upon the need to take care of their bodies and the environment; familiarize them with and help them to visualize some of the agents that frequently cause diseases among children in their community. Description: this proposal is undertaken in three encounters, through the presentation of two children's plays, a walk with children and teachers in the community and the improvisation of a laboratory, set up so that the children can visualize small animals. As a result, parents and teachers report modifications in children's behavior concerning personal hygiene and environmental care, and the children start to demand that adults adopt similar attitudes. The walk in the community provides the children with a new perspective on their surroundings and helps new teachers to gain a perspective on the school's community. Recommendation: through educational action based on dialogue, it is possible for children to gain the capacity to modify their environment and become familiar with their rights and duties. Above all, it contributes towards their sense of citizenship

Reuse of fruits and vegetables biowaste for sustainable development of natural ingredients

Considering the annual waste in the food sector that occurs throughout the value chain, it is important to establish strategic measures to reduce, value and reintroduce them into the industrial sector. Additionally, the constant search for the development of sustainable strategies to promote safe and healthy products for consumers has gained great prominence. Biowastes from fruits and vegetables present in their composition an excellent source of compounds of interest, which can be reused in different technological routes, providing added value in the industrial, socioeconomic and therapeutic sectors. In particular, the phenolic compounds present in fruit and vegetable biowastes, have bioactive and preservative characteristics that are excellent candidates for the development of natural ingredients that can be substitutes for synthetic preservatives. As the list of identified phenolic compounds is extensive and accessible, the interest in these compounds is gaining more and more prominence, since the use of ingredients of synthetic origin is being delayed by actions harmful to the health of the consumer. Phenolic compounds, in addition to having preservative capacity, such as antioxidant and antimicrobial capacity, are also known for their anti-inflammatory, anticancer, antidiabetic, antiallergic and other biological properties, which increases the interest in their use in functional and nutraceutical preparations. Based on this, this review gathers information on the impacts that the exacerbated generation of fruit and vegetable waste can generate in the environmental, economic and social sectors, as well as lists different ways of reusing these wastes, highlighting the characteristics of phenolic compounds.The authors are grateful to the Foundation for Science and Technology (FCT, Portugal) for financial support through national funds FCT/MCTES (PIDDAC) to CIMO (UIDB/00690/2020 and UIDP/00690/ 2020) and SusTEC (LA/P/0007/2021), national funding by F.C.T. for Tatiane C.G.

Total body percentage and motor coordination among Portuguese schoolchildren

Children’s motor coordination may affect their activity pattern and thereby influence their bodyfatness. The aim of the present study was to analyse the relationship between motor coordination and total body fat percentage, in a Portuguese sample of schoolchildren aged 9–12 years. Method: The sample comprised 596 urban schoolchildren (girls 46?9%), aged 9–12 years (mean 9?61 ( SD 0?55) years) from North of Portugal. Total body fat percentage was cal- culated with Tetrapolar Bioelectrical Impedance Analysis, model Tanita TBF-300. Age- and sex-adjusted Z-scores computed total body fat percentage. Motor coordination levels were assessed with the Ko¨rperkoordination Test fu¨r Kinder (KTK) and children were classified according to age and sex KTK criteria (Schiling 1974). Date of birth, gender and school socio-economic status (eligible for benefit A, B or not eligible) were extracted from the school administrations records systems. School socio-economic status was used as a proxy measure of family socio-economic status. Results: In motor coordination, 22?4 % girls showed disturbance of coordination; 37?7 % insufficiencies of coordination; 39?5 % normal coordination and 0?4 % good coordination. Corresponding figures for boys were 7?3 %; 36?5 %; 54?3 % and 1?9 %, respectively. Linear regression analysis showed that Z-scores total body fat percentage (unstandardized B 5 20?258, SE 0?021, P , 0?001) were negatively associated with motor coordination, after adjustment for socio-economic status. Conclusions: Low motor coordination levels are nega- tively associated with total body fat percentage Z-scores. The early identification of children with poor motor coor- dination and/or high body fat percentage is crucial in order to implement and develop health-related behaviours.

Dietary inclusion of blood hydrolysates affects muscle growth in European seabass (Dicentrarchus labrax)

Dietary supplementation with hydrolysates has been suggested to influence muscle protein synthesis and fish growth. This study assessed the impact of including 3% swine blood hydrolysates (BH) in a plant-based diet on muscle cellularity and the expression of molecular markers related to muscle fibre proliferation and hypertrophic growth of European seabass. Three BH fractions were obtained by two different processes, autohydrolysis (AH-H) and enzymatic hydrolysis followed by micro- (RMF-H) and nanofiltration (RNF-H). Each BH was added to a commercial-based diet, where 50% of fishmeal was replaced by vegetable proteins (negative control, NC). A fishmeal-based diet was used as positive control, PC. The diets were fed to juveniles (12 g) during 74 days. The RMF group showed down-regulation of myod1 and fgf4, essential to myoblast proliferation and differentiation, and upregulation of mafbx, responsible for protein breakdown, resulting in impairment of muscle hyperplasic growth and the lowest muscle fibres number. However, compensatory growth mechanisms were observed through capn1 downregulation and mymk upregulation, suggesting decreased muscle proteolysis and increased myoblast fusion. Despite this, the compensatory mechanisms were insufficient as RMF group had the worst growth. RNF group had a final weight similar to the NC, but downregulation of fgf4, fgf6 and capn1 may compromise growth potential at long term. The expression of these genes in the AH group was similar to that in the FM-based diet. Despite not having demonstrated growth promotion ability, BH affect muscle growth and cellularity factors, prompting further research on commercial-sized fish to reveal their impact on important commercial traits.info:eu-repo/semantics/publishedVersio

Chemical characterization of “Alcaparras” stoned table olives from Northeast Portugal

Commercial stoned table olives named "alcaparras" from Trás-os-Montes (Portugal) were chemically characterized. During three consecutive years (2004-2006) 30 samples (10 per year) were examined for their nutritional value (moisture, crude protein, total fat, ash, carbohydrates, and energy), with a detailed report of the fatty acids and tocopherols composition. Water was the major constituent (72.5 ± 5.5%), followed by fat (14.6 ± 5.1%). The average amount of protein and ash were 1.1% and 3.4%, respectively, reporting unusual ash values for table olives, related to the technological process. One hundred grams of fresh stoned table olives presented an average energetic value of 156 kcal, lower than most table olives. The lipids are rich in oleic acid (average of 77.7 ± 2.0%), followed by palmitic acid and linoleic acid. Samples showed an average of total tocopherols of 1.2 mg/100 g of fresh weight, being α-tocopherol the most abundant. Table olives are important sources of MUFA, as olive oil, recognized as a preventive factor in diseases in which free radicals are implicated, complemented by the amounts of vitamin E, with both antioxidant and vitamin action.The authors are grateful to INTERREG III A Program, Project PIREFI for financial support of this work.info:eu-repo/semantics/publishedVersio
