1. Antitumor effect of depsidones from lichens on tumor cell lines and experimental murine melanoma
Abstract Lichens have exhibited numerous biological activities, including growth inhibition of tumor cells. This study evaluated the antiproliferative activity of hypostictic and salazinic acids against tumor cell lines (B16-F10, PC-03, MCF7, HT-29, HEP-G2, K562 and 786-0) by the SRB assay in vitro and antitumor activity in experimental murine melanoma in vi

6. Evaluation of microorganisms with sulfidogenic metabolic potential under anaerobic conditions
The aim of this work was to identify groups of microorganisms that are capable of degrading organic matter utilizing sulfate as an electron acceptor. The assay applied for this purpose consisted of running batch reactors and monitoring lactate consumption, sulfate reduction and sulfide production. A portion of the lactate added to the batch reactors was cons

8. Correlação entre os ensaios de citotoxicidade em Artemia salina Leach e atividade antineoplásica sobre linhagens de células tumorais para algumas classes de produtos naturais / Correlation between the citotoxicity assays in Artemia salina Leach and antineoplasic activity on tumoral cell lines for some natural products groups
The aim of this study was to correlate qualitative and quantitatively the lethal concentration needed for the citotoxic test on Artemia salina with the inhibitory concentration for the growth of tumoral cell lines using ten pure substances already known. Estimates for the year 2008 and also valid for the year 2009, in Brazil, show the occurrence of 466.730 n

12. Phylogenetic Analysis Reveals Multiple Lateral Transfers of Adenosine-5′-Phosphosulfate Reductase Genes among Sulfate-Reducing Microorganisms
Lateral gene transfer affects the evolutionary path of key genes involved in ancient metabolic traits, such as sulfate respiration, even more than previously expected. In this study, the phylogeny of the adenosine-5′-phosphosulfate (APS) reductase was analyzed. APS reductase is a key enzyme in sulfate respiration present in all sulfate-respiring prokaryote
