PREDAÇÃO DE FRUTOS E DE LAGARTAS ARTIFICIAIS COMO PROPOSTA DE ATIVIDADE PRÁTICA PARA O ENSINO DE CIÊNCIAS

Aulas de Ciências incorporam uma motivação natural pelas vivências práticas que conduzem à investigação dos diversos aspectos da natureza. As atividades práticas contribuem para aproximar o conhecimento com as experiências vividas, além de despertar a curiosidade e o sentimento crítico. No entanto, a aplicação dessas atividades também envolve as condições de infraestrutura da escola e da própria dinâmica do experimento, idealmente optando por materiais acessíveis e não restritivos a grupos etários para maior viabilidade e visibilidade. Assim, propomos um experimento de Ciências sobre predação de frutos e de lagartas artificiais utilizando massa de modelar a base de cera. Buscamos sugerir uma alternativa prática de fácil obtenção e manipulação e com variada possibilidade didática

Consumo de suplementos nutricionais por praticantes de musculação da cidade de São Carlos-SP

Introdução: Alimentação adequada é fator determinante à qualidade de vida e melhora do desempenho físico. A falta de conhecimento sobre os SAs associados à prescrição por profissionais não habilitados, autoprescrição ou indicação de amigos são fatores preocupantes podendo estar em risco à saúde do indivíduo. Objetivo: Investigar o consumo e o conhecimento sobre SAs de indivíduos que realizam treinamento de musculação na cidade de São Carlos-SP. Material e Métodos: Estudo transversal com análise descritiva dos dados, onde foram analisados o consumo e o conhecimento sobre SAs por 400 indivíduos que praticam musculação do município de São Carlos-SP. Resultados: A média de idade entre os participantes foi de 27,9anos (±9,66). 54,5% dos entrevistados possuem ensino médio completo e 31,8% ensino superior completo. 64% relataram consumir SAs, independente do tipo, classe ou objetivo do consumo. Em relação à avaliação da quantidade de SAs consumidos 64,1% dos indivíduos afirmaram que consomem de 1 a 3 tipos. Os SAs mais consumidos foram os proteicos, com destaque para Whey Protein (84%) e Brached-Chain Amino Acids (57%). Foi possível perceber uma diferença entre os gêneros em relação ao terceiro suplemento mais consumido, pois entre os homens foi creatina e entre as mulheres foi cafeína. Conclusões: A maioria dos praticantes de musculação jovens adultos consome SA. Prevalece a prescrição dos mesmos por profissionais não qualificados, fato que demonstra a demanda aumentada por profissionais habilitados e qualificados em nutrição esportiva para orientar, prescrever e supervisionar de forma adequada a suplementação alimentar nos ambientes esportivos.  ABSTRACTNutritional Supplements consumption by bodybuilders of Sao Carlos-SPIntroduction: Adequate nutrition is a determining factor for good life quality and improved physical performance. The lack of knowledge about Nutritional Supplements (NS) associated with prescription not qualified professionals, self prescription or indication friends are worrying factors may be at risk to the health of the individual. Objective: To investigate the use and knowledge of NS to individuals who perform strength training in São Carlos-SP. Results: The mean age of the participants was 27.9 years (± 9.66). 54.5% of respondents have completed secondary education and 31.8% university degree. 64% reported consuming the NS, regardless of the type and class or purpose of consumption. It was observed that consumption was 77% higher among men compared to women. Regarding the assessment of the amount of consumed NS, 64.1% of subjects reported consuming 1-3 types. The most consumed NS were protein, especially whey protein (84%) and Chain Amino Acids-Brached (57%), less than half of the volunteers reported consuming Creatine (44%) and maltodextrin (28%). It was possible to notice a difference between the genders regarding the third most consumed supplement because among men was creatine and among women was caffeine. Discussion and Conclusion: Most young adults bodybuilding practitioners consumes SA. The prescription of these is still performed by unqualified practitioners. Which demonstrates the increased demand for skilled and qualified professionals in sports nutrition to guide, prescribe and supervise adequately the food supplementation in sports environments.

Evaluation Of Hypoxia Inducible Factor Targeting Pharmacological Drugs As Antileishmanial Agents

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)To evaluate whether hypoxia inducible factor (HIF-1 alpha) targeting pharmacological drugs, echinomycin, resveratrol and CdCl2, which inhibit HIF-1 alpha stimulation, and mimosine, which enhances the stability of HIF-1 alpha present antileishmanial properties. Methods: The leishmanicidal effect of drugs was evaluated in mouse macrophages and Balb/c mouse model for cutaneous leishmaniosis. Results: Resveratrol and CdCl2, reduced the parasite load [IC50, (27.3 +/- 2.25) mu M and (24.8 +/- 0.95) mu M, respectively]. The IC50 value of echinomycin was (22.7 +/- 7.36) mu M and mimosine did not alter the parasite load in primary macrophages. The macrophage viability IC50 values for resveratrol, echinomycin and CdCl2, and mimosine were >40 mu M, >100 mu M > 200 mu M and>2 000 mu M, respectively. In vivo no differences between cutaneous lesions from control, resveratrol- and echinomycin-treated Balb/c mice were detected. Conclusions: Resveratrol, echinomycin and CdCl2, reduce parasite survival in vitro. The HIF-1 alpha targeting pharmacological drugs require further study to more fully determine their anti-Leishmania potential and their role in therapeutic strategies.97633638Fundacao de Amparo a Pesquisa do Estado de Sao Paulo, BrazilConselho Nacional de Desenvolvimento Cientifico e Tecnologico, Brazil [2009/10771-9]Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior, Brazil [301052/2009-3]Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

Secular trends in body image dissatisfaction and associated factors among adolescents (2007–2017/2018)

Objective To assess secular trends in body image dissatisfaction and associated factors among adolescents over a 10-year period (2007-2017/2018). Methods The sample included 1,479 (2007, n = 531; 2017/2018, n = 948) high school adolescents of both sexes, aged 14 to 18 years, of schools in a city in southern Brazil, in 2007 and 2017/2018. Data were collected on sex, age, physical activity (IPAQ, short form), anthropometric measurements (body weight, height, and triceps and subscapular skinfolds), and body image dissatisfaction (figure rating scale). The variables were compared with Independent samples t-test and Mann–Whitney U-test. The associations between sex and other variables were examined with chi-square test, and the factors associated with body image were identified with multinomial logistic regression. Results Most adolescents were dissatisfied with their body image in 2007 (65,2%) and 2017/2018 (71,1%). The prevalence of body dissatisfaction increased by 9.2% over the 10-year period, particularly dissatisfaction with thinness (21.3%). After stratification by sex, in 2017/2018 sample, dissatisfaction with overweight was 46.1% greater in boys, and dissatisfaction with thinness was 66.9% greater in girls. Factors found to be significantly associated with body image dissatisfaction were physical activity level, and body adiposity. Conclusions There was a secular trend toward increased body image dissatisfaction in both sexes. Future efforts should go beyond scientific production, in public and private environments aimed at increasing awareness of health issues related to body care in the physical, psychological, and environmental domains
