Developmental morphology of mouthparts and foregut of the larvae and postlarvae of Lepidophthalmus siriboia Felder & Rodrigues, 1993 (Decapoda: Callianassidae)

A morfologia dos apêndices bucais e o estômago de larvas e pós-larvas de Lepidophthalmus siriboia cultivados em laboratório foi investigada. Os apêndices bucais (maxilas e maxilípedes) durante os estágios zoeae apresentam número reduzido de cerdas e espinhos, ou mesmo, ausentes em alguns indivíduos. O estômago aparece pouco desenvolvido, com poucas cerdas pequenas nas câmaras cardíaca e pilórica. Contrariamente, após a metamorfose para o estágio megalopa, todas estas estruturas bucais possuem muitas cerdas, e o estômago apresenta um moinho gástrico bem desenvolvido com dois fortes dentes laterais. No estágio juvenil ocorre incremento de cerdas e espinhos em todas estruturas bucais e o estômago torna-se mais especializado. Estas observações sugerem fortemente que as zoeae de L. siriboia têm desenvolvimento lecitotrófico, mas que as megalopae e juvenis passam a ingerir alimentos exógenos.

Soroprevalência de infecções por vírus da hepatite B e vírus da hepatite C em indivíduos do Estado do Pará

As hepatites B e C continuam sendo um importante problema de saúde pública no Brasil. Neste estudo, determinou-se a prevalência de marcadores sorológicos para as hepatites B e C em indivíduos do Estado do Pará, atendidos no Laboratório Central de Saúde Pública do Pará, no período de janeiro de 2002 a dezembro de 2005. Foram realizados 11.282 exames para a pesquisa do HBsAg, 2.342 para o anti-HBc e 5.542 para o anti-vírus da hepatite C. A prevalência de HBsAg foi de 3,6% e predominou na faixa etária de 20 a 29 anos, enquanto que o anti-HBc foi observado em 37,7% dos indivíduos. A prevalência do antivírus da hepatite C foi de 3,6% e predominou entre indivíduos acima de 50 anos. Assim, as freqüências dos marcadores encontradas no Pará foram mais altas que em vários outros estados do país, sugerindo a necessidade de medidas de saúde publica mais eficazes no combate a estes agravos na região.

Divergent evolution and purifying selection of the H (FUT1) gene in New World monkeys (Primates, Platyrrhini)

In the present study, the coding region of the H gene was sequenced and analyzed in fourteen genera of New World primates (Alouatta, Aotus, Ateles, Brachyteles, Cacajao, Callicebus, Callithrix, Cebus, Chiropotes, Lagothrix, Leontopithecus, Pithecia, Saguinus, and Saimiri), in order to investigate the evolution of the gene. The analyses revealed that this coding region contains 1,101 nucleotides, with the exception of Brachyteles, the callitrichines (Callithrix, Leontopithecus, and Saguinus) and one species of Callicebus (moloch), in which one codon was deleted. In the primates studied, the high GC content (63%), the nonrandom distribution of codons and the low evolution rate of the gene (0.513 substitutions/site/MA in the order Primates) suggest the action of a purifying type of selective pressure, confirmed by the Z-test. Our analyses did not identify mutations equivalent to those responsible for the H-deficient phenotypes found in humans, nor any other alteration that might explain the lack of expression of the gene in the erythrocytes of Neotropical monkeys. The phylogenetic trees obtained for the H gene and the distance matrix data suggest the occurrence of divergent evolution in the primates.

Os cursos de Pedagogia da Universidade Estadual Paulista e a Educação Inclusiva

Inclusive education is seen as quality education that should be provided by the educational system for all children, young people and adults. In order to put such a proposal into effect, qualified personnel are needed who are equipped to face such a challenge. This paper aims to examine the curriculum matrices of Pedagogy courses of the Universidade Estadual Paulista - UNESP that intend to prepare future teachers to follow an inclusive perspective. To this end, the political-pedagogical projects of six Pedagogy courses, the University resolutions that regulate the courses and excerpts taken from interviews carried out with course coordinators were analyzed. In order to analyze the curriculum matrices, the required subjects were distributed on a table according to the following categories: 1) specific subjects related to inclusive education, 2) number of hours of each subject related to inclusive education, 3) specific subjects related to special education and 4) amount of time scheduled for each subject related to special education. Among the six Pedagogy courses, five had subjects that focused on issues related to inclusive education, with varying time allotments, and four had subjects focusing on specific issues related to special education.

Prevalence of antibodies against Toxoplasma gondii and Neospora caninum in dogs

Toxoplasmosis and neosporosis are parasitic diseases of global importance. The present study had the objective to determine the influence of age, sex and breed in the prevalence of antibodies against both diseases in dogs from Brotas city, São Paulo State, Brazil. Blood samples of 342 dogs were collected, and the age, sex and breed of each animal were recorded. The serological diagnosis for toxoplasmosis and neosporosis were performed using the immunofluorescent antibody test (IFAT). The Fischer's test was used to calculate the association probability of the variables, with a = 5%. For toxoplasmosis the prevalence of antibodies was 26.9% (CI 95% 22.4-31.8%), and for neosporosis 4.97% (CI 95% 3.1-7.8%). The statistical analysis revealed a higher risk of infection for T. gondii in dogs with more than five years.
