Evaluation report: regional training workshop on data sharing, data ownerhsip and the harmonization of survey datasets

As part of ongoing efforts to strengthen the statistical capacities of National Statistical Offices (NSOs) in the region, the Economic Commission for Latin America and the Caribbean (ECLAC) convened a two-day Regional Training Workshop on Data Sharing, Data Ownership and Harmonization of Survey Datasets on 26-27 August 2009 at the Cascadia Hotel, Trinidad and Tobago. This workshop was one of the concluding activities of the Project on Improving Household Surveys in the Caribbean which has been implemented by the ECLAC Subregional office from 2007.

Mitochondrial DNA-like sequence in the nuclear genome of Saguinus (Callitrichinae, Primates): transfer estimation

Seqüências tipo mitocondriais têm comumente sido encontradas no genoma nuclear de diversos organismos. Quando acidentalmente incluídas em estudos de seqüências mitocondriais, diversas conclusões errôneas podem ser obtidas. No entanto, estes pseudogenes nucleares tipo mitocondriais podem ser usados para a estimativa da taxa relativa de evolução de genes mitocondriais e também como grupo externo em análises filogenéticas. No presente trabalho, seqüências mitocondriais com características do tipo de pseudogene, tais como deleções e/ou inserções e códons de parada, foram encontradas em tamarins (Saguinus spp., Callitrichinae, Primates). A análise filogenética permitiu a estimativa do tempo da migração da seqüência mitocondrial para o genoma nuclear e algumas inferências filogenéticas. A escolha de um grupo externo não adequado (Aotus infulatus) não permitiu uma reconstrução filogenética confiável da subfamília Callitrichinae. A divergência bastante antiga de Cebidae (Callitrichinae, Aotinae e Cebinae) pode ter favorecido o aparecimento de homoplasias, obscurecendo a análise.

Sequence characterization of coding regions of the myostatin gene (GDF8) from Brazilian Murrah buffaloes (Bubalus bubalis) and comparison with the Bos taurus sequence

Within about 30 years the Brazilian buffalo (Bubalus bubalis) herd will reach approximately 50 million head as a result of the great adaptive capacity of these animals to tropical climates, together with the good productive and reproductive potential which make these animals an important animal protein source for poor and developing countries. The myostatin gene (GDF8) is important in the physiology of stock animals because its product produces a direct effect on muscle development and consequently also on meat production. The myostatin sequence is known in several mammalian species and shows a high degree of amino acid sequence conservation, although the presence of non-silent and silent changes in the coding sequences and several alterations in the introns and untranslated regions have been identified. The objective of our work was to characterize the myostatin coding regions of B. bubalis (Murrah breed) and to compare them with the Bos taurus regions looking for variations in nucleotide and protein sequences. In this way, we were able to identify 12 variations at DNA level and five alterations on the presumed myostatin protein sequence as compared to non double-muscled bovine sequences.

Phylogenetic relationships of Malassezia species based on multilocus sequence analysis

Members of the genus Malassezia are lipophilic basidiomycetous yeasts, which are part of the normal cutaneous microbiota of humans and other warm-blooded animals. Currently, this genus consists of 14 species that have been characterized by phenetic and molecular methods. Although several molecular methods have been used to identify and/or differentiate Malassezia species, the sequencing of the rRNA genes and the chitin synthase-2 gene (CHS2) are the most widely employed. There is little information about the beta-tubulin gene in the genus Malassezia, a gene has been used for the analysis of complex species groups. The aim of the present study was to sequence a fragment of the beta-tubulin gene of Malassezia species and analyze their phylogenetic relationship using a multilocus sequence approach based on two rRNA genes (ITS including 5.8S rRNA and D1/D2 region of 26S rRNA) together with two protein encoding genes (CHS2 and beta-tubulin). The phylogenetic study of the partial beta-tubulin gene sequences indicated that this molecular marker can be used to assess diversity and identify new species. The multilocus sequence analysis of the four loci provides robust support to delineate species at the terminal nodes and could help to estimate divergence times for the origin and diversification of Malassezia species.
