Leishmania (Viannia) lainsoni: occurrence of intracellular promastigote forms in vivo and in vitro
Corrêa, José R;Soares, Maurilio J;
Memórias do Instituto Oswaldo Cruz , 2006, DOI: 10.1590/S0074-02762006000800016
Abstract: experimental chronic (45-day-old) skin lesion in hamster hind foot induced by leishmania (viannia) lainsoni infection showed the presence of promastigote forms in the tissue, inside parasitophorous vacuoles, as assessed by transmission electron microscopy. experimental in vitro interaction (24 and 48 h) between leishmania (v.)lainsoni and j774-g8 macrophage cells also demonstrated the same profile. this morphological aspect is unusual, since in this parasite genus only amastigote forms have been described as the resistant and obligate intracellular forms.
Leishmania (Viannia) lainsoni (Kinetoplastida: Trypanosomatidae), a divergent Leishmania of the Viannia subgenus: a mini review
Corrêa, José R;Brazil, Reginaldo P;Soares, Maurilio J;
Memórias do Instituto Oswaldo Cruz , 2005, DOI: 10.1590/S0074-02762005000600014
Abstract: leishmania (viannia) lainsoni is the leishmania species that presents the most distinct biological (morphology, growth in axenic culture medium), biochemical (enzymatic electrophoresis profile), and molecular biology characteristics, when compared to other species of the viannia subgenus. development of promastigote forms of this parasite attached to the wall of the pyloric and hind gut regions of sand fly vectors is a solid characteristic that allows its positioning in the viannia subgenus. however, taxonomic data from biochemical and molecular techniques on this leishmania species are still not conclusive. it is evident the difficulty in taxonomically positioning this borderline leishmania species. in this review we present the data accumulated since l. (viannia) lainsoni has been described and we discuss its position in the viannia subgenus.

Abstract:
Transferrin uptake may occur through detergent-resistant membrane domains at the cytopharynx of Trypanosoma cruzi epimastigote forms
Corrêa, José R;Atella, Georgia C;Vargas, Camila;Soares, Maurilio J;
Memórias do Instituto Oswaldo Cruz , 2007, DOI: 10.1590/S0074-02762007005000117
Abstract: uptake of transferrin by epimastigote forms of the protozoan trypanosoma cruzi occurs mainly through a cytostome/ cytopharynx, via uncoated endocytic vesicles that bud off from the bottom of the cytopharynx. we have here examined whether detergent-resistant membrane (drm) domains might be involved in this process. purified whole cell membrane fractions were assayed for cholesterol levels and used in dot blot analyses. detergent-resistant membrane markers (cholera b toxin and anti-flotillin-1 antibody) presented positive reaction by dot blots in cholesterol-rich/ protein-poor membrane sub-fractions. the positive dot blot fraction was submitted to lipid composition analysis, showing composition similar to that of raft fractions described for other eukaryotic cells. immunofluorescence assays allowed the localization of punctual positive signal for flotillin-1, matching the precise cytostome/ cytopharynx location. these data were confirmed by immunofluorescence assays with the co-localization of flotillin-1 and the transferrin uptake site. our data suggest that drm domains occur and are integrated at the cytostome/ cytopharynx of t. cruzi epimastigotes, being the main route for transferrin uptake.
Characterization of TcSTI-1, a homologue of stress-induced protein-1, in Trypanosoma cruzi
Schmidt, Juliana C;Soares, Maurilio J;Goldenberg, Samuel;Pavoni, Daniela Parada;Krieger, Marco A;
Memórias do Instituto Oswaldo Cruz , 2011, DOI: 10.1590/S0074-02762011000100012
Abstract: the life cycle of the protozoan trypanosoma cruzi exposes it to several environmental stresses in its invertebrate and vertebrate hosts. stress conditions are involved in parasite differentiation, but little is known about the stress response proteins involved. we report here the first characterization of stress-induced protein-1 (sti-1) in t. cruzi (tcsti-1). this co-chaperone is produced in response to stress and mediates the formation of a complex between the stress proteins hsp70 and hsp90 in other organisms. despite the similarity of tcsti-1 to sti-1 proteins in other organisms, its expression profile in response to various stress conditions, such as heat shock, acidic ph or nutrient starvation, is quite different. neither polysomal mrna nor protein levels changed in exponentially growing epimastigotes cultured under any of the stress conditions studied. increased levels of tcsti-1 were observed in epimastigotes subjected to nutritional stress in the late growth phase. co-immunoprecipitation assays revealed an association between tcsti-1 and tchsp70 in t. cruzi epimastigotes. immunolocalization demonstrated that tcsti-1 was distributed throughout the cytoplasm and there was some colocalization of tcsti-1 and tchsp70 around the nucleus. thus, tcsti-1 associates with tchsp70 and tcsti-1 expression is induced when the parasites are subjected to stress conditions during specific growth phase.

Abstract:


In this study, the essential oils extracted from the peels of Citrus aurantifolia, Citrus limon and Citrus sinensis were chemically characterized and quantified. These essential oils and their standards limonene, citral and limonene + citral were evaluated (at concentrations ranging from 500 to 3.91 mL·mL-1) regarding their anti-trypanosome, antifungal and antibacterial activities. The chemical identification and quantification (by GC/FID and GC/MS) displayed the limonene as the major component of the three essential oils. It did not verified anti-trypanosome activity for all treatments. Regarding antimicrobial activity, the results were satisfactory against Gram-negative bacteria (Staphylococcus aureus, Listeria. monocytogenes and Salmonella cholerasuis) and funghi

Forma e ethos do trabalho: ensaio sobre a reformula??o de uma ideologia
Botelho, Maurilio Lima;
Revista Katálysis , 2009, DOI: 10.1590/S1414-49802009000200009
Abstract: this essay explores the changes in the so-called ideology of labor, from the classic protestant work ethic, passing through the hedonism of consumer society to the current reformulation of this ideology in a society in crisis. it emphasizes that the modifications occur both in the form and content of this ideology, which stimulates an analysis of its relationship with social reality.
