Revista de Saúde Pública: 50 years disseminating the knowledge in nutrition

ABSTRACT This work describes and comments on articles in the area of Public Health Nutrition published in Revista de Saúde Pública (RSP – Public Health Journal) from 1967 to 2016. We searched in the PubMed database restricted to the periodical “Revista de Saúde Pública” and using terms related to key topics in the area of Public Health Nutrition. We retrieved 742 articles and, after exclusion of duplicates and articles unrelated to the subject, we analyzed 441 articles, grouped according to subject: dental caries, anemia, hypovitaminosis A, macro/micronutrients, malnutrition, nutritional assessment, overweight/obesity, food consumption, low birthweight, and breastfeeding. We observed significant increase in the number of articles published and diversification of subjects addressed over the 50 years, representing the consistent development of the scientific field of Nutrition in Brazil. Since its inception, RSP has played an important role in the dissemination of knowledge about the main nutritional issues in Brazil

A Preliminary and Qualitative Metallomics Study of Mercury in the Muscle of Fish from Amazonas, Brazil

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)This paper presents preliminary findings for a metallomics study of mercury in the muscle of the fish species from Amazonas, Brazil, after protein separation by two-dimensional polyacrylamide gel electrophoresis and subsequent evaluation of mercury by synchrotron radiation X-ray fluorescence. The fluorescence spectra revealed mercury in two protein spots. The mercury-containing protein spots showed molecular weights of 20.8 +/- 0.7 and 19.8 +/- 0.5 kDa and isoelectric points of 5.6 +/- 0.2 and 7.5 +/- 0.3, respectively.15041699195199Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FAPESP [2010/51332-5, 2009/54856-8

Genetic parameter and correlation estimates of processing traits in half-sib progenies of tropical-adapted carrot germplasm Parâmetros genéticos e correlações entre características para processamento em progênies de meios-irmãos de germoplasma de cenoura tropical

The estimate of the genetic parameters associated with processing (fresh-cut) traits, including root length (RL), is crucial for carrot breeding programs in tropical areas. The cultivar Alvorada is an important germplasm due to its resistance to nematodes, leaf blight, heat-tolerance, and high carotenoid content. Seventy-four 'Alvorada' half-sib progenies were evaluated during the summer of 2005 in the Federal District, Brazil, in a randomized complete block design with three replications. Thirteen competitive plants in each block were randomly selected and evaluated and/or classified for RL and for number of leaves (NL), leaf length (LL), root tip type (RT), root mass (RW), crown shape (CS), root diameter (RD), and xylem diameter (XD). The Pearson's correlation coefficients and the heritability values were estimated for all traits. The path analysis was also used considering the RL trait as dependent variable. The heritability for RL ranged from 12 to 44%. For the other traits, the values ranged from 3% (RD) to 79% (LL). Phenotypic and genotypic correlations among all traits were low to intermediate. Path analysis indicated positive direct relationship between RL and RW, whereas RD and XD displayed negative direct effect on RL. Longer roots had narrow diameter and narrow XD. Recurrent selection based upon either half-sib or S1 families would be more effective than mass phenotypic recurrent selection in increasing RL and to develop populations expressing multiple desirable processing traits in tropical-adapted carrot germplasm.<br>A estimativa de parâmetros genéticos associados com caracteres de processamento industrial, incluindo comprimento de raiz (RL), é crucial para programas de melhoramento de cenoura para áreas tropicais. A cultivar Alvorada é um importante germoplasma devido à sua resistência a nematóides e queima-das-folhas, tolerância ao calor e alto conteúdo de carotenóides. Setenta e quatro progênies meio-irmãs derivadas de 'Alvorada' foram avaliadas durante o verão de 2005 no Distrito Federal (DF), em blocos casualizados com três repetições. Treze plantas competitivas em cada bloco foram selecionadas ao acaso e avaliadas ou classificadas para RL, número de folhas (NL), comprimento de folhas (LL), tipo de ponta de raiz (RT), massa de raiz (RW), formato do ombro da raiz (CS), diâmetro da raiz (RD) e diâmetro do xilema (XD). Foi estimada a correlação de Pearson entre os caracteres, realizada a análise de trilha considerando RL como a variável dependente; o coeficiente de herdabilidade e outros parâmetros genéticos. Os valores de herdabilidade para RL variaram entre 12 e 44%. Para os outros caracteres, os valores variaram de 3% (RD) a 79% (LL). Os valores observados para as correlações fenotípicas e genotípicas entre todos os caracteres variaram de baixos a intermediários. A análise de trilha indicou efeito positivo para a relação entre RL e RW, muito embora RD e XD tivessem efeitos diretos negativos em RL. Maiores raizes apresentaram menores diâmetros e menores XD. Métodos de seleção recorrente baseados em meio-irmãos ou famílias S1 podem ser mais efetivos que seleção recorrente fenotípica massal no aumento de RL e no desenvolvimento de populações com caracteres desejáveis para o processamento em germoplasma de cenoura tropical
