This article analyses the emergence and development of social policies for children and adolescents attendance that are in line with the development process of the Brazilian social protection system, focusing on some of the main representations attributed to childhood, according to the historical and political periods. It seeks to present the notion of childhood instituted under the constitution of the Brazilian welfare state, in such a way as to place it within the broader context of the historical and political transformations that involved the emergence and consolidation of the social policies directed towards children and adolescents in Brazil in the 20th century and the beginning of the 21st.

Chemical research in Brazil has grown significantly in the past 20 years, largely thanks to the Brazilian S&T Development Program of the federal government (PADCT). However, the newly achieved levels of highly qualified manpower and research infra-structure require new research organization frameworks to make science, technology and innovation really useful and meaningful for the citizens. The current requirements for creating viable networks of academic and industry researchers are presented and discussed as well as some structural and procedural bottlenecks that have to be eliminated, to achieve maximum high-quality science, technology and relevant innovation output.

The Jaguariaiva region is located at Parana State, southern Brazil, and it keeps up the last remnants of savanna vegetation in the State. Thus, it should be considered a mark of the meridional distribution limit of this vegetation type in Brazil. The Parque Estadual do Cerrado (24º09' S; 50º18' WG), whose vegetation is not solely composed by savanna forms, was the object of this study that analysed the vegetation of two dominant savanna physiognomic types (cerrado sensu stricto and campo cerrado). Twenty quadrats of 200m² (20 x 10m) were sistematicaly established in each physiognomic unit, and all the individuals having Basal Perimeter (BP) over 15 cm were sampled. The survey results indicated a low number of woody species in both units (33 species in cerrado sensu stricto and 18 in campo cerrrado). Most important species were virtually the same for both units, specially Byrsonima coccolobifolia, Acosinium subelegans, Couepia grandiflora and Stryphnodendron adstringens. The total density, total dominance and diversity were higher in cerrado sensu stricto. Moreover. there was apparently a higher lloristic resemblance with savannas of São Paulo State, specially those located in the South of thc State.

We estimate litter production and leaf decomposition rate in a cerradão area, physiognomy little studied and very threatened in São Paulo State. During the period of study, litter production was 5646.9 kg.ha-1.year-1, which the 'leaf' fraction corresponded to 4081.2 kg.ha¹.year¹; the 'branch' fraction, to 1066.1 kg.ha-1.year-1; the 'reproductive structures' fraction, to 434.1 kg.ha-1.year-1; and the 'miscellaneous' fraction to 65.5 kg.ha-1.year-1. Litter production was highly seasonal and negatively correlated with relative humidity and air temperature. Leaf production was negatively correlated with relative humidity, rainfall, and air temperature. There was no significant difference between litter production found in this study and those in two other sites with cerradão and semideciduous forest, but these physiognomies differed significantly from the cerrado sensu stricto. Leaf decomposition rate (K) was 0.56. Half-life of the decomposing material was 1.8 years and turnover time was 2.3 years.

In 2004, Costa-Santos and cols. reported 24 patients from 19 Brazilian families with 17α-hydroxylase deficiency and showed that p.W406R and p.R362C corresponded to 50% and 32% of CYP17A1 mutant alleles, respectively. The present report describes clinical and molecular data of six patients from three inbred Brazilian families with 17α-hydroxlyse deficiency. All patients had hypogonadism, amenorrhea and hypertension at diagnosis. Two sisters were found to be 46,XY with both gonads palpable in the inguinal region. All patients presented hypergonadotrophic hypogonadism, with high levels of ACTH (> 104 ng/mL), suppressed plasmatic renin activity, low levels of potassium (< 2.8 mEq/L) and elevated progesterone levels (> 4.4 ng/mL). Three of them, including two sisters, were homozygous for p.W406R mutation and the other three (two sisters and one cousin) were homozygous for p.R362C. The finding of p.W406R and p.R362C in the CYP17A1 gene here reported in additional families, confirms them as the most frequent mutations causing complete combined 17α-hydroxylase/17,20-lyase deficiency in Brazilian patients.
