Effect of Fertilization Regime of Common Wheat (Triticum aestivum) on Flour Quality and Shelf-Life of PDO Tuscan Bread

The shelf-life of bread is influenced by flour components, such as starch, composed of amylose and amylopectin. The aim was to test the effect of different balances of N (45, 90, 135 kg/ha) and P (48, 96 kg/ha) fertilizers on the flour characteristics and consequently the shelf-life of PDO Tuscan bread, stored in different modified atmosphere packaging (Ar, N2, Air). The amylose and phytochemical compounds were increased by N and decreased by the addition of P, but excessive doses of N (135 kg/ha) had a negative effect on flour quality. In the bread, the study highlighted the tendency of N2 and Ar, as storage filler gases, to reduce water loss, slow down the staling process, and prolong shelf-life. However, the most significant influence on shelf-life was related to the different fertilizations of wheat. In fact, when N was present in equal dose to P (90/96 or 45/48 kg/ha) or slightly higher (90/48 kg/ha), the bread tended to last longer over time. Instead, when these ratios were unbalanced in favor of N (135/48 or 135/96 kg/ha) and in favor of P (45/96 kg/ha), the shelf-life decreased considerably

Health Through a Human Right Lens at the US-Mexico Border: Increasing Access to Healthcare for Central American Immigrants

The number of immigrants seeking entry into the U.S. through asylum requests or through irregular means is increasing, and most come from the Northern Triangle of El Salvador, Guatemala, and Honduras. Immigrants come fleeing extreme poverty, violence, health and social inequities, and drastic climate changes. Most had limited access to healthcare at home, and even more limited care along the journey. Those that are allowed entry into the U.S., are confronted with feeling unwelcome in many communities, having to navigate an array of local, state, and federal laws that regulate access to healthcare. We need immigration policies that preserve the health, dignity with a multinational policy for provision of healthcare through a human rights lens from point of origin to point of destination

Projeto Licenciar Biologia: Educação em Saúde no Ensino de Ciências

O Ensino de Ciências e a Educação em Saúde têm um importante papel na educação básica, principalmente em tempos de pandemia e desinformação. O objetivo deste trabalho é relatar e divulgar as ações desenvolvidas no âmbito do Projeto “Licenciar Biologia: Educação em Saúde no Ensino de Ciências” da Universidade Federal do Paraná – Setor Palotina. O projeto teve como objetivo construir propostas teórico-metodológicas e materiais didáticos interdisciplinares para a Educação em Saúde no Ensino de Ciências, na escola. Para tanto, foram desenvolvidos materiais didáticos que podem ser utilizados como estratégias educacionais: um jogo educacional digital, uma história em quadrinhos e um vídeo animado sobre vacinas. Todos os materiais desenvolvidos tiveram como foco a Educação em Saúde sob uma perspectiva pedagógica, fundamentada pela alfabetização científica no Ensino de Ciências. No decorrer das atividades do projeto, percebeu-se que as estratégias utilizadas para o desenvolvimento dos materiais didáticos configuraram-se como um espaço-tempo destinado à formação de professores, favorecendo a construção de conhecimentos profissionais docentes dos participantes. 

Sealability of MTA and calcium hydroxidecontaining sealers

OBJECTIVES: The aim of this study was to evaluate the apical sealability of Fillapex(®), Endo-CPM-Sealer(®) and Sealapex(®). MATERIAL AND METHODS: Ninety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite. The teeth were randomly divided in groups of 10 specimens each according to the sealer, and the canals were filled using the single cone technique and one of the sealers. Four additional teeth were used as controls. The teeth were submitted to dye leakage with Rhodamine B for 24 h but using vacuum on the initial 15 min. Thereafter, they were cut longitudinally and the leakage was measured in a linear fashion from apex to crown. Data were analyzed by ANOVA and Tukey's tests at 5% significance level. RESULTS: Fillapex(®) and Sealapex(®) showed significantly less dye leakage than Endo-CPM-Sealer(®) (p<0.05). CONCLUSIONS: It was concluded that Fillapex(®) and Sealapex(®) were able to prevent apical dye leakage differently from Endo-CPM-Sealer(®)
