Morphology and biological aspects of Gundlachia ticaga from SE Brazil (Gastropoda: Basommatophora: Ancylidae)

Some aspects of the biology, reproduction and morphology of Gundlachia ticaga (MARCUS & MARCUS 1962) were studied and compared with literature data. A sample of similar to 100 specimens, collected in a darn in Ribeirao Preto, were maintained in Petri dishes at the laboratory during a period no longer than a month. The oviposition, number of capsules, and incubation time of eggs were registered for each individual. A morphologic study was carried out in both, alive and fixed specimens. Although some morphological discrepancies were identified, the majority of data confirms what was previously described for the species. Regarding the biology, however, the results were somewhat different from those previously reported. The incubation time of the eggs varied from 10 to 13 days, and the number of embryos in the interior of the ovigerous capsules varied from 1 to 4. In addition, each individual laid 9 eggs during the first month of the reproductive period. The formation of septa occurred in some animals and intermediary phases are figured.

Between the court and the revolution: the role of one ""merchant"" in America, capital of portuguese Empire

The article discusses the trajectory of Manuel Luis da Veiga which, as a merchant in Portugal (where he was born) invested to install a factory in Pernambuco after the arrival of Real Family in the Rio de Janeiro, considering the changes, in these days, in the Portuguese Empire. It focuses the political sociabilities, remarking the role of Veiga in the court and his writings on political economy, understanding both as two linked dimensions of his social practice. It points out that his trajectory shows a deeply changing world in terms of paradigms, impossible to be understood simply in patterns of what was old or new in the beginning of XIX century.

Alves C. J., Alcino J. F., Farias A. E. M., Higino S. S. S., Santos F. A., Azevedo S. S., Costa D. F. & Santos C. S. A. B. 2012. [Epidemiological characterization and risk factors associated with leptospirosis in the brazilian semiarid.] Caracterizacao epidemiologica e fatores de risco associados a leptospirose em ovinos deslanados do semiarido brasileiro. Pesquisa Veterinaria Brasileira 32(6): 523-528. Universidade Federal de Campina Grande, Centro de Sa de e Tecnologia Rural, Unidade Academica de Medicina Veterinaria, Av. Universitaria s/n(o), Patos, PB 58700-970, Brazil. E-mail: clebertja@uol.com.br The aim of this investigation was to determine the herd-level and animal-level prevalence of leptospirosis in sheep from the semiarid of Paraiba State, Northeast Brazil, as well as to identify risk factors. Blood samples were collected from 1,275 sheep from 117 flocks in 19 counties in the Sertao mesoregion, Paraiba. For the serological diagnosis of leptospirosis the microscopic agglutination test (MAT) using 24 Leptospira spp. serovars as antigens was carried out. Of the 117 flocks studied 33 (28.20%) presented at least one seropositive sheep, and of the 1,275 animals 69 (5.41%) were seropositive with titers ranging from 100 to 3,200. Reactant serovars were Autumnalis (49.30%), Andamana (27.53%), Sentot (17.39%), Whitcomb (4.34%) and Australis (1.44%). Herd size > 48 sheep (odds ratio = 2.26; 95% CI = 1.33-5.07; p = 0.021) and participation in animal exhibits (odds ratio = 9.05; 95% CI = 0.96-85.71; p = 0.055) were identified as risk factors. The need was suggested for studies on the isolation of the agent, characterization of its pathogenicity and its economic impact on sheep flocks of the region, and sanitary control in sheep agglomerations was recommended.

Gametic phase disequilibrium between the syntenic multiallelic HTG4 and HMS3 markers widely used for parentage testing in Thoroughbred horses

Validation of parentage and horse breed registries through DNA typing relies on estimates of random match probabilities with DNA profiles generated from multiple polymorphic loci. Of the twenty-seven microsatellite loci recommended by the International Society for Animal Genetics for parentage testing in Thoroughbred horses, eleven are located on five chromosomes. An important aspect in determining combined exclusion probabilities is the ascertainment of the genetic linkage status of syntenic markers, which may affect reliable use of the product rule in estimating random match probabilities. In principle, linked markers can be in gametic phase disequilibrium (GD). We aimed at determining the extent, by frequency and strength, of GD between the HTG4 and HMS3 multiallelic loci, syntenic on chromosome 9. We typed the qualified offspring (n (1) = 27; n (2) = 14) of two Quarter Bred stallions (registered by the Brazilian Association of Quarter Horse Breeders) and 121 unrelated horses from the same breed. In the 41 informative meioses analyzed, the frequency of recombination between the HTG4 and HMS3 loci was 0.27. Consistent with genetic map distances, this recombination rate does not fit to the theoretical distribution for independently segregated markers. We estimated sign-based D' coefficients as a measure of GD, and showed that the HTG4 and HMS3 loci are in significant, yet partial and weak, disequilibrium, with two allele pairs involved (HTG4*M/HMS3*P, D'(+) = 0.6274; and HTG4*K/HMS3*P, D'(-) = -0.6096). These results warn against the inadequate inclusion of genetically linked markers in the calculation of combined power of discrimination for Thoroughbred parentage validation.

Avaliação psicológica de pacientes com anorexia e bulimia nervosas: indicadores do Método de Rorschach

Este estudo teve por objetivo avaliar o funcionamento lógico, afetivo e a adaptação social de pacientes com Anorexia Nervosa (AN) e Bulimia Nervosa (BN). A amostra foi composta por 27 participantes. Para coleta dos dados foi utilizado o Método de Rorschach. Os dados foram codificado e interpretados segundo as normas da Escola Francesa. Os resultados indicaram que os participantes apresentam capacidade produtiva e desejo de estabelecerem relacionamentos afetivos. Todavia, são facilmente invadidos por uma carga de afetos que não conseguem modular, o que os predispõe ao isolamento social, que gera acúmulo de inquietações e ansiedades introjetadas. A incapacidade de elaborar a tensão interna resultante os leva a escoar a ansiedade pela via somática. Evidenciou-se o comprometimento das funções psíquicas dos pacientes com AN e BN, o que indica a necessidade de acompanhamento psicoterapêutico integrado à assistência da equipe multiprofissional.

Sociedade Tarja Preta: uma crítica à medicalização de crianças e adolescentes

Como breve análise do livro "Medicalização de crianças e adolescentes: conflitos silenciados pela redução de questões sociais a doenças de indivíduos", esta resenha contextualiza a importância da publicação na crítica contemporânea à invenção de (psico)patologias e tratamentos a elas destinados. O livro logra, de forma extremamente rigorosa, desconstruir as "bases científicas" que sustentam o transtorno de déficit de atenção e hiperatividade (TDAH), mostrando como a indústria farmacêutica vem ocultando sistematicamente os profundos efeitos colaterais do princípio ativo destinado a tratá-lo (o metilfenidato, presente na Ritalina® e Concerta®). Com textos de profissionais vinculados à saúde e educação, nas mais diferentes áreas do conhecimento, o livro representa uma notável coalizão de esforços em benefício da promoção dos direitos de crianças e adolescentes.

Serological, clinical and epidemiological evaluation of toxocariasis in urban areas of south Brazil.

Toxocariasis is a worldwide public-health problem that poses major risks to children who may accidentally ingest embryonated eggs of Toxocara. The objectives of this study were to investigate the occurrence of anti-Toxocara spp. antibodies in children and adolescents and the variables that may be involved, as well as environmental contamination by Toxocara spp. eggs, in urban recreation areas of north central mesoregion, Paraná State, Brazil. From June 2005 to March 2007. a total of 376 blood samples were collected by the Public Health Service from children and adolescents one to 12 years old, of both genders. Samples were analyzed by the indirect ELISA method for detection of anti-Toxocara antibodies. Serum samples were previously absorbed with Ascaris suum antigens, and considered positive with a reagent reactivity index ≥1. Soil samples from all of the public squares and schools located in the four evaluated municipalities that had sand surfaces (n = 19) or lawns (n = 15) were analyzed. Of the 376 serum samples, 194 (51.6%) were positive. The seroprevalence rate was substantially higher among children aging one to five years (p = 0.001) and six to eight years (p = 0.022). The clinical signs and symptoms investigated did not show a statistical difference between seropositive and seronegative individuals (p > 0.05). In 76.5% of the investigated recreation places, eggs of Toxocara were detected in at least one of the five collected samples. Recreation areas from public schools were 2.8 times more contaminated than from public squares. It is important to institute educational programs to inform families and educators, as well as to improve sanitary control of animals and cleaning of the areas intended for recreation in order to prevent toxocariasis.
