ABSTRACT
RESUMO No Nordeste do Brasil é bastante comum e variado o uso da coroa-de-frade (Melocactus spp.). Assim, o objetivo deste estudo foi realizar diversas análises em cladódios de coroa-de-frade [Melocactus zehntneri (Britton & Rose) Luetzelburg], para que possamos compreender as razões estes usos. Os cladódios foram coletados na cidade de Campina Grande e levados ao Laboratório de Engenharia de Alimentos da Universidade Federal de Campina Grande, onde foram feitas as seguintes análises: peso, altura, diâmetro, cor, umidade, acidez, pH, ácido ascórbico, carotenoides, flavonoides e compostos fenólicos, tanto na epiderme quanto no parênquima aquífero. Os resultados mostraram que a epiderme tem uma acidez elevada e mais ácido ascórbico, e um pH mais baixo em comparação com o parênquima aquífero. O conteúdo de carotenoides, flavonoides e compostos fenólicos, foram diferentes nas partes estudadas. A epiderme apresentou sempre maiores quantidades de carotenoides, flavonoides e compostos fenólicos em relação ao parênquima aquífero, nas três plantas estudadas, indicando que a maior parte da defesa da planta acontece neste tecido. Mais estudos são necessários com técnicas mais precisas, para identificar os componentes bioativos desta espécie.
ABSTRACT In Northeast Brazil, the use of melon cactus (Melocactus spp.) is quite common and varied. Thus, the present study aimed to perform various analyzes in cladodes of melon cactus [Melocactus zehntneri (Britton & Rose) Luetzelburg], to understand the reasons for the use of this species. The cladodes were collected in the city of Campina Grande and taken to the Food Engineering Laboratory of the Federal University of Campina Grande, where we performed the following analyses: mass, height, diameter, color, moisture, acidity, pH, ascorbic acid, carotenoids, flavonoids and phenolic compounds, both in the epidermis and in the aquifer parenchyma. The results showed that the epidermis has a higher acidity, ascorbic acid content and lower pH compared to the aquifer parenchyma. The contents of carotenoids, flavonoids and phenolic compounds, were different from the both parts analyzed. The epidermis always had greater quantities of carotenoids, flavonoids and phenolic compounds than the aquifer parenchyma for the three plants, showing that most of the plant defense takes place in this tissue. Further studies, with more accurate techniques, are needed to identify the bioactive components of this species.

Objetivo Evaluar la reproducibilidad intra e interevaluador de la Escala Motriz del Infante de Alberta (AIMS), Canadá, aplicada por fisioterapeutas en formación de último nivel. Materiales y métodos Se realizó un estudio de evaluación de pruebas diagnósticas en 21 infantes clínicamente sanos de ambos géneros, entre 0 y 18 meses residentes de la ciudad de Bucaramanga, Colombia. La evaluación fue realizada por 12 evaluadores, 11 fisioterapeutas en formación de último nivel y un fisioterapeuta con experiencia en el área pediátrica, con un intervalo de una semana y mediante vídeo. El análisis de reproducibilidad intra y entre evaluadores se estableció con el coeficiente de correlación intraclase (CCI) y adicionalmente se calculó el error estándar de la medición (EEM), considerando un α=0,05.ResultadosSe encontró una muy buena reproducibilidad interevaluadores para el puntaje total de la escala (CCI>0,98) y para la subescala en sedente (CCI>0,97). El análisis para las otras subescalas mostró CCI moderados entre 0,54 y 0,64. La reproducibilidad intraevaluador registró coeficientes entre bajos y excelentes. El EEM fue bajo para las subescalas de pie, en prono y el puntaje total (0,20-0,77).Conclusiones La AIMS es un instrumento reproducible, que puede ser utilizado en nuestro contexto por fisioterapeutas en formación para la evaluación del desarrollo motor en niños clínicamente sanos (AU)
Objective To evaluate the intra- and inter-rater reliability of the Alberta Infant Motor Scale (AIMS) applied by final level undergraduate physiotherapy students. Materials and methods An assessment of evaluation of diagnostic tests was done in 21 clinically healthy infants of both genders, aged 0 to 18 months, residents at Bucaramanga, Colombia. The evaluation was conducted by 12 raters, 11 physiotherapy students in final level and a physiotherapist with experience in pediatrics. The assessments were performed with an interval of one week and by video. An Intraclass Correlation Coefficient (ICC) was applied for the reliability analysis and Standard Error of Measurement (SEM) was obtained, considering an α=0.05.ResultsA very good inter-rater reliability for the total score (ICC>0.98) and the sitting subscale (ICC>0.97) were registered. The other subscales showed moderate reliability, ICC between 0.54 and 0.64. Intra-rater reliability showed low to excellent ICC. The SEM was low for the standing, prone subscales and total score (0.20 to 0.77).Conclusions The AIMS is a reliable tool that can be used in our context by undergraduate physical therapy students in their year of study in order to assess motor development in clinically healthy children (AU)
