13. In vivo antithrombotic properties of a heparin from the oocyte test cells of the sea squirt Styela plicata(Chordata-Tunicata)
In the ascidian Styela plicata, the oocytes are surrounded by two types of accessory cells named follicle cells and test cells. A heparin-like substance with an anticoagulant activity equivalent to 10% of mammalian heparin and about 5% as potent as the mammalian counterpart for the inhibition of thrombin by antithrombin was isolated from the oocyte test cell

14. Macrozooplâncton da Zona Econômica Exclusiva do Nordeste do Brasil (segunda expedição oceanográfica - REVIZEE/NE II) com ênfase em Copepoda (Crustacea)
Objetivando-se caracterizar a densidade, abundância relativa, freqüência de ocorrência, diversidade específica e associação de espécies do macrozooplâncton oceânico da "Zona Econômica Exclusiva" foi realizado o presente estudo. A região prospectada encontra-se localizada entre os paralelos 7º28'56"S - 34º32'45"W, referente a segunda expedição

15. Biodiversidade e Biomassa do MacrozooplÃncton, com Ãnfase nos Copepoda (Crustacea), na Plataforma Continental Norte Brasileira
Estudos sobre a influÃncia da pluma estuarina do rio Amazonas na comunidade macrozooplanctÃnica foram desenvolvidos visando conhecer a biodiversidade e o gradiente de densidade. A Ãrea estudada està inserida na Zona EconÃmica Exclusiva (ZEE) brasileira e mais especificamente na Plataforma Continental Norte Brasileira (PCNB), tendo sido subdividida em tr

16. "Ascidiacea (Chordata: Tunicata) from brazilian tropical coast" / "Ascidiacea (Chordata: Tunicata) do litoral tropical brasileiro"
Embora tenham sido muito estudadas em diversos pontos do globo, as ascídias do litoral brasileiro são pouco conhecidas. A maior parte do litoral brasileiro está incluída na região tropical, para qual as informações são mais escassas. Com o intuito de se conhecer a fauna de ascídias do litoral tropical brasileiro foram realizadas diversas coletas em

17. MacrozooplÃncton da zona econÃmica exclusiva do Nordeste do Brasil (revizee neii e neiii) com Ãnfase em Copepoda
The macrozooplankton from the Economic Exclusive Zone of Northeastern Brazil (7O28â56âS - 34O32â45âW ; 7O30â30âS - 34O29â08âW) was studied to assess its diversity and distribution. Samples were collected at 44 stations from 31/01 to 07/02/92(NE-II) and from 11 to 16/05/98 (NE-III by the Oceanographic Ship Antares from the Brazilian Navy. A bongo net

18. Evolution of the chordate body plan: New insights from phylogenetic analyses of deuterostome phyla
The deuterostome phyla include Echinodermata, Hemichordata, and Chordata. Chordata is composed of three subphyla, Vertebrata, Cephalochordata (Branchiostoma), and Urochordata (Tunicata). Careful analysis of a new 18S rDNA data set indicates that deuterostomes are composed of two major clades: chordates and echinoderms + hemichordates. This analysis strongly

19. Update of AMmtDB: a database of multi-aligned Metazoa mitochondrial DNA sequences
The AMmtDB database (http://bio-www.ba.cnr.it:8000/srs6/ ) has been updated by collecting the multi-aligned sequences of Chordata mitochondrial genes coding for proteins and tRNAs. The genes coding for proteins are multi-aligned based on the translated sequences and both the nucleotide and amino acid multi-alignments are provided. AMmtDB data selected throug

20. Update of AMmtDB: a database of multi-aligned Metazoa mitochondrial DNA sequences
The AMmtDB database (http://bighost.area.ba.cnr.it/mitochondriome) has been updated by collecting the multi-aligned sequences of Chordata and Invertebrata mitochondrial genes coding for proteins and tRNAs. Links to the multi-aligned mtDNA intraspecies variants, collected in VarMmtDB at the Mitochondriome web site, have been introduced. The genes coding for p

21. Transmission Genetics of Allorecognition in Hydractinia Symbiolongicarpus (Cnidaria: Hydrozoa)
Allorecognition is ubiquitous, or nearly so, amongst colonial invertebrates. Despite the prominent role that such phenomena have played both in evolutionary theory and in speculations on the origin of the vertebrate immune system, unambiguous data on the transmission genetics of fusibility (i.e., the ability of two individuals to fuse upon tissue contact) is

22. Transcript Mapping and Genome Annotation of Ascidian mtDNA Using EST Data
Mitochondrial transcripts of two ascidian species were reconstructed through sequence assembly of publicly available ESTs resembling mitochondrial DNA sequences (mt-ESTs). This strategy allowed us to analyze processing and mapping of the mitochondrial transcripts and to investigate the gene organization of a previously uncharacterized mitochondrial genom

23. DoOP: Databases of Orthologous Promoters, collections of clusters of orthologous upstream sequences from chordates and plants
DoOP (http://doop.abc.hu/) is a database of eukaryotic promoter sequences (upstream regions) aiming to facilitate the recognition of regulatory sites conserved between species. The annotated first exons of human and Arabidopsis thaliana genes were used as queries in BLAST searches to collect the most closely related orthologous first exon sequences from Chor

24. Capture of heat-killed Mycobacterium bovis bacillus Calmette-Guérin by intelectin-1 deposited on cell surfaces
Intelectin is an extracellular animal lectin found in chordata. Although human and mouse intelectin-1 recognize galactofuranosyl residues included in cell walls of various microorganisms, the physiological function of mammalian intelectin had been unclear. In this study, we found that human intelectin-1 was a serum protein and bound to Mycobacterium bovis ba
