| Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and... |

| Foram estudados 24 cavalos atletas hígidos, machos, adultos, da raça Puro Sangue Lusitano, submetidos a esforço físico de trote e galope de rotina do animal, com o objetivo de avaliar a configuração do traçado do eletrocardiograma (ECG) em repouso, mediante eletrocardiografia computadorizada, bem como os efeitos do exercício físico sobre os parâmetros clínicos e eletrocardiográficos destes animais. Foram avaliados exame físico e ritmo cardíaco antes e imediatamente após o exercício físico, assim como as distintas configurações de ondas p e complexos QRS, obtidas ao ECG de repouso. Após o treinamento, ocorreram taquicardia e taquipneia. O ritmo predominante no repouso foi o sinusal e, após o exercício, a taquicardia sinusal. Na morfologia das ondas,... |

| When compared to other model organisms whose genome is sequenced, the number of mutations identified in the mouse appears extremely reduced and this situation seriously hampers our understanding of mammalian gene function(s). Another important consequence of this shortage is that a majority of human genetic diseases still await an animal model. To improve the situation, two strategies are currently used: the first makes use of embryonic stem cells, in which one can induce knockout mutations almost at will; the second consists of a genome-wide random chemical mutagenesis, followed by screening for mutant phenotypes and subsequent identification of the genetic alteration(s). Several projects are now in progress making use of one or the other of these... |
