| O objetivo deste trabalho foi realizar a caracterização molecular de 11 acessos de Cratylia argentea, com base no sequenciamento da região ITS (ITS1/5,8S/ITS2), bem como o estabelecimento de suas relações filogenéticas com outras leguminosas. As relações filogenéticas dessa espécie com outras 15 leguminosas foram estabelecidas com o uso de sequência do gene que codifica a subunidade 18S do rRNA (rDNA 18S). A amplificação do DNA da região ITS/5,8S dos 11 acessos revelou uma única banda de aproximadamente 650 pb. Sequências ITS/5,8S foram obtidas de todos os acessos analisados e depois alinhadas com a região ITS/5,8S da leguminosa Galactia striata. O tamanho das sequências ITS/5,8S dos acessos de C. argentea variou de 565 a 615 pb. Os conteúdos médios de G +... |

| The lectins, proteins which specifically recognize carbohydrate moieties, have been extensively studied in many biochemical and structural aspects in order to establish the molecular basis of this non-catalytic event. On the other hand, their clinical and agricultural potentials have been growing fast. Although lectins, mainly those from legume plants, had been investigated for biological properties, studies about the physiological functions of lectins are scarce in literature. Therefore, despite the accumulated data on lectins (as proteins), the role played by these signalizing molecules is poorly discussed. In the light of our accumulated results on legume lectins, specially those obtained from plants belonging to the Diocleinae sub-tribe and available... |

| Infection with both Human Immunodeficiency Virus (HIV) and Mycobacterium tuberculosis is currently the world's leading cause of death due to infectious agents. We evaluated factors related to the development of tuberculosis (TB) in HIV-infected patients who were being treated at an infectious diseases hospital in Fortaleza, Ceará, Brazil. From January 2004 to December 2005, we made an epidemiological study through the analysis of the medical records of 171 patients, who were diagnosed as having both HIV and tuberculosis. Among these co-infected patients, most (81%, p=0.0006) were male. Co-infection was more frequent (87.8%) among patients over 40 years of age and those with lower educational levels (less than eight years of schooling). Forty-one percent of... |

| Chamaecrista belongs to subtribe Cassiinae (Caesalpinioideae), and it comprises over 330 species, divided into six sections. The section Xerocalyx has been subjected to a profound taxonomic shuffling over the years. Therefore, we conducted a phylogenetic analysis using a cpDNA trnE-trnT intergenic spacer and nrDNA ITS/5.8S sequences from Cassiinae taxa, in an attempt to elucidate the relationships within this section from Chamaecrista. The tree topology was congruent between the two data sets studied in which the monophyly of the genus Chamaecrista was strongly supported. Our analyses reinforce that new sectional boundaries must be defined in the Chamaecrista genus, especially the inclusion of sections Caliciopsis and Xerocalyx in sect. Chamaecrista,... |
