DNA barcoding of Brazilian sea turtles (Testudines)

Five out of the seven recognized species of sea turtles (Testudines) occur on the Brazilian coast. The Barcode Initiative is an effort to undertake a molecular inventory of Earth biodiversity. Cytochrome Oxidase c subunit I (COI) molecular tags for sea turtle species have not yet been described. In this study, COI sequences for the five species of sea turtles that occur in Brazil were generated. These presented widely divergent haplotypes. All observed values were on the same range as those already described for other animal groups: the overall mean distance was 8.2%, the mean distance between families (Dermochelyidae and Cheloniidae) 11.7%, the mean intraspecific divergence 0.34%, and the mean distance within Cheloniidae 6.4%, this being 19-fold higher than the mean divergence observed within species. We obtained species-specific COI barcode tags that can be used for identifying each of the marine turtle species studied

Adequação de recursos humanos ao PSF: percepção de formandos de dois modelos de formação acadêmica em odontologia The Family Health Program (FHP) and human resources: perceptions of students from two different dentistry schools

O Programa Saúde da Família - PSF foi instituído pelo governo federal objetivando reverter o modelo assistencial. Os recursos humanos envolvidos devem estar preparados para alcançar os objetivos que o PSF propõe. O propósito desse artigo foi avaliar os desejos, percepções e preparo de acadêmicos de Odontologia, em relação aos princípios do PSF, de duas diferentes Faculdades de Odontologia, aqui denominadas Faculdades 1 e 2. Buscou-se ainda analisar se as faculdades tiveram potencial transformador sobre os acadêmicos, graduando-os com compromisso social e sensibilidade humanitária, considerados importantes para aqueles que querem trabalhar no PSF. Questionários individuais foram aplicados por um único pesquisador. As respostas foram analisadas pelo programa Epi-Info. Os resultados mostraram que prevalece entre os acadêmicos o desejo de trabalhar no PSF por razões ligadas às dificuldades do mercado de trabalho e os mesmos citam freqüentemente a técnica como a principal característica necessária a um dentista para que o mesmo atue no PSF. Por outro lado, diferenças estatisticamente significativas foram encontradas entre os acadêmicos, apontando uma provável influência do Estágio Supervisionado, ministrado sob a forma de internato rural, sobre a formação do acadêmico da Faculdade 1, possivelmente habilitando-o melhor para o PSF.<br>The purpose of this study was to evaluate the perceptions and opinions of dental students from two different Dentistry Schools in Brazil, both known here as Dentistry Schools 1 and 2 about the Family Health Program - FHP. The study analyzed if the Dentistry Schools had any influence on the students, graduating professionals with humanitarian and social sensibility, which are considered very important prerequisites for those who wish to work on this governmental health program, as well as searching for professional expectation of the students. Individual questionnaires were applied by only one researcher among the students who took part in the study. Answers were analysed by the Epi-Info program and results showed that difficulties related to the job market may be influencing students to join the FHP. Results also reveal that students consider technician an important prerequisite for dentists who wish to work on this governmental program. Significant statistical differences between the students were found: those who were graduating in Dentistry School 1 seemed more adequate to FHP and the reason for this difference may be the Supervised Training Program, a unit available on this Dentistry School that enables the students face the reality of FHP, as well the social and economical reality of the families assisted by this program
