2012) Composition and antioxidant activity of honey from Africanized and stingless bees in Alagoas (Brazil): a multivariate analysis, Journal of Apicultural Research, 51:1, 23-35 To link to this article: http://dx. SummaryThe purpose of this study was to evaluate the antioxidant activity of honey from different entomological sources which were harvested in the dry season of 2008-2009 from distinct mesoregions of the State of Alagoas in the North East of Brazil. Honey produced by five different species of bees, even from the same region and season, showed a statistically significant difference (p <0.05) in the content of phenols, flavonoids and antioxidants, with higher levels of these compounds found in honey produced by Plebeia spp. and A. mellifera. Honey from stingless bees was quite different from that of A. mellifera, especially from the Plebeia spp. A dendrogram of the five species of bees showed the formation of 3 groups, one being formed by Apis mellifera, one by the genus Melipona (M. subnitida, M. quadrifasciata and M. scutellaris) and another formed by Plebeia spp.Composición y actividad antioxidante de la miel de abejas africanizadas y sin aguijón en Alagoas (Brasil): un análisis multivariante Resumen El propósito de este estudio fue evaluar la actividad antioxidante de la miel de diferentes fuentes entomológicas que se recogieron en la estación seca de 2008-2009 de distintas mesorregiones del Estado de Alagoas en el noreste de Brasil. La miel producida por cinco especies distintas de abejas, incluso de la misma región y de temporada, mostró una diferencia estadísticamente significativa (p < 0,05) en el contenido de fenoles, flavonoides y antioxidantes, con mayores niveles de estos compuestos se encuentran en la miel producida por Plebeia spp y A. mellifera. La miel de las abejas sin aguijón era muy diferente de la de A. mellifera, especialmente de las especies de Plebeia. Un dendrograma de las cinco especies de abejas mostró la formación de tres grupos, uno de ellos formado por Apis mellifera, uno por el género Melipona (M. subnitida, M. quadrifasciata y M. scutellaris) y otro formado por Plebeia spp.M. scutellaris, this parameter varied from 4.67-52.56 mg GA equivalent / 100 g (mean 18.45 ± 11.41 mg. GA equivalent / 100 g), being lower than in honey from Apis, Fig. 1.In honey from M. quadrifasciata, M. subnitida and Plebeia spp., the antioxidants averages, according to this method were 32.96 ± 30.67, 16.19 ± 5.76 and 49.91 ± 21.36 mg GA equivalent / 100 g, respectively. Statistically significant correlations (p < 0.01) were observed between the content of total phenolics and FRAP (r = 0.814) and between the total flavonoid content and FRAP (0.795), demonstrating, again, the contribution of these compounds in the antioxidant activity of honey. There was also a statistically significant correlation between the content expressed by FRAP and the antioxidant content by DPPH expressed as GA (r = 0.584) and Q (r = 0.568), Table 2.

This study was designed to assess the predictors of a higher blood pressure (BP) in a clinical setting in a prospective cohort of normotensive children recruited in an outpatient pediatric clinical setting in Southern Brazil. The study evaluated 443 children 3–12 years of age. If the mean value of BP was greater than the 95th percentile for age, sex and height in the medical setting, children were scheduled to other two evaluations at home. The systolic BP percentile in the clinical consultation was associated with BMI and birth weight. The diastolic BP in the clinical consultation was associated with birth weight, age, and BMI. Weight excess, low birth weight and younger age were associated with a higher BP in normotensive children seen in a clinical setting. To our knowledge, this is the first study to describe the association between lower birth weight and a greater BP response to medical consultation. Our finding suggests that the tendency to higher white-coat effect is determined, at least to some extent, in intrauterine life.

BIOECOLOGY OF Goniopsis cruentata (Latreille, 1803) (Decapoda, Grapsidae) OF THE MUNDAÚ/MANGUABA ESTUARY-LAGOON COMPLEX, ALAGOAS, BRAZIL ABSTRACTConsidering the ecological importance of Goniopsis cruentata (Latreille, 1803) and the scarcity of studies about this species in the northeastern coast of Brazil, this paper aims to expand the knowledge of the bioecology of this species in the Mundaú / Manguaba Estuarine Lagoon Complex (CELMM), State of Alagoas, Brazil. The samplings of G. cruentata were monthly accomplished, in the months of September 2005 to July 2006, at four stations in CELMM. The specimens were identified, sexed and measured at carapace width (CW), carapace length (CL) and wet weight (WW). The sex ratio, the power regression correlating CL vs. CW and WW vs. CW, the catch per unit effort (CPUE) in terms of number of crabs / collector / hour, and the reproductive period of the species were obtained. A total of 585 specimens of Goniopsis cruentata were sampled, being 318 males and 267 females. The sex ratio for the total sample was 1:0.78, with males being more abundant than females. Males were significantly larger and heavier. The CPUE varied among sampling sites, being significantly lower at stations 1 and 4, the most impacted ones. The regressions between CL vs. CW and WW vs. CW revealed that the growth of males and females is allometrically positive. Ovigerous females were found in nearly all months of sampling. The present study provides evidence of environmental impacts in the population, through changes in the sex ratio and CPUE, demonstrating that this animal is a good bioindicator of impacts from deforestation and solid waste disposal.
