2. Ediacaran emerald mineralization in Northeastern Brazil: the case of the Fazenda Bonfim Deposit
Abstract The Fazenda Bonfim emerald deposit lies within the Seridó Belt. It is a classic example of deposit formed through metasomatic interactions between Be-rich granite intrusions and Cr(± V)-rich mafic-ultramafic rocks. The setting of the emerald mineralization was built under strong strike-slip dynamics, which produced serpentinization and talcificati

4. USE OF VIRGINIAMYCIN AND SALINOMYCIN IN THE DIET OF BEEF CATTLE REARED UNDER GRAZING DURING THE RAINY SEASON: PERFORMANCE AND RUMINAL METABOLISM
Resumo O rúmen é o órgão mais estudado no que se refere à interação simbiótica entre hospedeiro e a microbiota do trato digestivo dos ruminantes. Assim, objetivou-se avaliar os efeitos da inclusão de virginiamicina e de salinomicina ao suplemento para bovinos de corte com dieta de gramínea tropical no período das águas. Foram constituídos três

6. Efficacy of sertraline against Trypanosoma cruzi: an in vitro and in silico study
Abstract Background: Drug repurposing has been an interesting and cost-effective approach, especially for neglected diseases, such as Chagas disease. Methods: In this work, we studied the activity of the antidepressant drug sertraline against Trypanosoma cruzi trypomastigotes and intracellular amastigotes of the Y and Tulahuen strains, and investigated its

7. Sporotrichosis: an update on epidemiology, etiopathogenesis, laboratory and clinical therapeutics
Abstract: In the late 90's there was a change in both the route of transmission and the people at risk for sporotrichosis. This zoonotic cat-man alternative transmission route elicited changes in strategies to control the epidemic. There was a progressive increase in the number of cases involving especially children and the elderly. In addition to becoming h

8. Protection mediated by chemokine CXCL10 in BALB/c mice infected by Leishmania infantum
BACKGROUND Visceral leishmaniasis (VL) caused by Leishmania infantum is characterised by the loss of the ability of the host to generate an effective immune response. Chemokines have a direct involvement in the pathogenesis of leishmaniasis, causing a rapid change in the expression of these molecules during infection by Leishmania. OBJECTIVES Herein, it

9. Electronic Effect of V, Ti, and Sc Impurities on the Hyperfine Interactions of Fe Atoms in α-Fe: A First Principles Study
The Linearized Augmented Plane Wave method, as implemented in the Wien2k computational code, was used to investigate the effects of the 3d transition metals (TM) Sc, Ti, and V impurities on the hyperfine interaction of iron atoms in α-Fe. The calculation results of this study suggest that the introduction of a TM (TM = Sc, Ti, and V) impurity into α-Fe inc

10. Osteogenic potential of periodontal ligament stem cells are unaffected after exposure to lipopolysaccharides
Abstract Periodontitis develops as a result of a continuous interaction between host cells and subgingival pathogenic bacteria. The periodontium has a limited capacity for regeneration, probably due to changes in periodontal ligament stem cells (PDLSCs) phenotype. The aim of this study was to evaluate the effects of lipopolysaccharides from Porphyromonas gin

11. Fluorescent membrane markers elucidate the association of Borrelia burgdorferi with tick cell lines
This study aimed to describe the association of Borrelia burgdorferi s.s. with ixodid tick cell lines by flow cytometry and fluorescence and confocal microscopy. Spirochetes were stained with a fluorescent membrane marker (PKH67 or PKH26), inoculated into 8 different tick cell lines and incubated at 30°C for 24 h. PKH efficiently stained B. burgdorferi with

12. Size and flight ability of Telenomus remus parasitoids reared on eggs of the factitious host Corcyra cephalonica
ABSTRACT In two independent bioassays, size and flight ability of parasitoids reared on eggs of Corcyra cephalonica for 19 generations and parasitoids reared on a natural host (Spodoptera frugiperda eggs) for 250 generations were compared as fast quality control procedures for insect rearing. The size of parasitoids was examined by morphometric analysis usin
