Abstract: the clinical significance of isolated anti-hbc is still a challenge. to elucidate the real importance of this finding in our blood donors, an investigation algorithm was tested. one hundred and twelve isolated anti-hbc seropositive blood donors underwent clinical evaluation and retesting of hbv markers. those who presented repeatedly reactive isolated anti-hbc, received a single dose of hepatitis b recombinant vaccine to verify anti-hbs early response. a hbv-dna determination by pcr was done for those who did not test positive to anti-hbs after vaccine. the level of anti-hbc was recorded as a ratio of the sample-to-cut-off values (s:c ratio) in 57 candidates at donation. comparing true and false-positive anti-hbc results, the different s:c ratios of them were statistically significant and when less than 2, implying in a false-positive result probability over 80%. a high percent of false-positive results (16.07%) was verified after anti-hbc retesting. hbv immunity was characterized in 49.11%, either by anti-hbs detection in retesting (15.18%), or after a single dose hbv vaccination (33.93%). hbv-dna was negative in all tested donors. in conclusion, this algorithm was useful to clarify the meaning of isolated anti-hbc in most of our blood donors.

Abstract: O objetivo do presente experimento foi avaliar a resposta ao bST de vacas mesti as (Bos taurus x Bos indicus) criadas no semi-árido do Ceará. Quinze vacas (segunda e terceira pari es; 42 a 155 dias pós-parto) receberam cinco aplica es de bST a intervalos de 14 dias e outras 15 foram utilizadas como controle. A dieta dos animais consistiu de capim-elefante e concentrado. Durante a primeira aplica o de bST, a produ o de leite dos animais tratados (12,6 kg/dia) n o diferiu dos animais controle (11,3 Kg/dia) mas, na segunda e terceira aplica es, a diferen a entre os grupos foi significativa (2,0 e 2,2 kg). Na quarta aplica o de bST, houve aumento na diferen a entre os grupos (3,0 kg) e, na quinta aplica o, esta diferen a foi de 3,4 kg (14,0 kg versus 10,6 kg/dia). A intera o tratamento com bST e estágio de lacta o n o foi significativa. As temperaturas do leite e retal foram maiores (0,6 e 0,1°C, respectivamente) nos animais tratados com bST que nos animais controles, mas estas diferen as n o foram significativas. Para o grupo de 30 animais, houve correla es entre produ o e temperatura do leite (r = 0, 38 a 0,69). Com base no cálculo do índice de temperatura e umidade, os animais estiveram submetidos a estresse térmico ameno (manh ) ou moderado (à tarde). Portanto, animais mesti os criados no semi-árido do Nordeste aumentaram a produ o de leite devido ao bST, sem, no entanto, apresentar indicativos de estresse térmico severo.

Abstract: the purpose of this study was too understand the dynamic of the social representations concerning children and adolescents, among the social representatives who participated in the 1987-88 national constitution assembly, in which children and adolescents were given their legal protection rights. the public dealings granted to the child and the adolescent, in the social brazilian history were approached as a locus of representations, spaces and social practices. the investigation advanced into its empirical universe, the national constitution assembly, which elaborated the federal constitution, with legal innovations for the child and the adolescent. the analysis lead to discoveries in a two-way direction: the distancing between the constitution process and the constitution text; the distancing of the constitution outcome and the brazilian social thoughts. brazil after the constituent assembly is updated, having as analytical reference the social representations of children and adolescents.

Abstract: the accumulated productivity (acp) is an index that takes into account the total weight of calves weaned per cow (in kg), total time required for producing the calves and age at first calving. a study was conducted to estimate the components of genetic and residual variance and estimate the heritability of acp index. data set consisted of 2,816 observations of nelore cows raised in different farms of the brazilian north and northeast. these farms participate in the genetic improvement program of the nelore breed. the observed mean and respective standard deviation for acp was 96.74 ± 46.70 kg of weaned calves/cow/year, with a coefficient of variation of 48.27%. this mean acp, however, is lower than values estimated in other herds of the nelore genetic program. also, standard nelore cows showed higher acp in comparison to cows of the nelore polled variety. estimated heritability for acp was 0.11 ± 0.06, suggesting that there is sufficient genetic variability that justify the use of acp in genetic selection. however, results of such strategy depend, mainly, on efficient herd management.

Abstract: the objective of this study was to estimate genetic and phenotypic parameters for reproductive traits of nelore cows raised in the north and northeast regions of brazil. the traits studied were age at first calving (afc), calving interval (ci), post-partum interval (ppi), number of services per conception (nsc) and gestation length (gl). the statistical analyses were done using the sas program (statistical analysis system) and variance components were estimated by restricted maximum likelihood method using the mtdfreml software. means and heritability estimates for afc, ci, ppi, nsc and gl were 45.14±10.83 months; 465.55±128.49 days; 165.76±110.29 days; 1.34±0.67 services and 295.03±5.85 days and 0.21±0.05; 0.05±0.02; 0.32±0.11; 0.05±0.04 e 0.12±0.04, respectively. the repeatability for ci, ppi, nsc and gl were, respectively, 0.05; 0.63; 0.09 and 0.22. the results suggest that despite the small genetic variability for the reproductive traits, afc and gl must be included in selection programs. the high heritability estimate for ppi is probably associated to the structure of the data, in its majority coming from the same herd. the repeatability estimate for ci suggests that female culling based on first calving interval is not accurate and there is a risk of culling animals with probable good reproductive efficiency.
