The H-NS protein has emerged as one of the leading causes of transcriptional repression in Gram-negative bacteria. In a paper published in this issue, De la Cruz and colleagues shed new light on the role of DNA curvature in the repressive mechanism, using a porin gene promoter from the human pathogen Salmonella Typhi as their experimental system (De la Cruz et al., 2009). Their data help to dee...

Antibodies Tiam1 antibodies were purchased (Santa Cruz) or generated by immunizing rabbits with GST-Tiam1 PDZ (aa 840–1025). Specificity of the Tiam1 antibodies was tested with peptide competition experiments (data not shown) and confirmed with RNAi (Figures 4A and 7B). Antibodies against pPak were generated previously (Shamah et al., 2001). Antibodies against the following proteins were purcha...

This article follows the career of the Brazilian physician Henrique da Rocha Lima, one of the first to join the group of young researchers working at the Instituto Soroterápico de Manguinhos (Instituto Oswaldo Cruz). It describes his first voyage to Germany where he specialized in microbiology and pathological anatomy, training that shaped his subsequent professional identity. The tensions and ...

In the Materials and Methods section, there is an error in the fifth and sixth sentences of the section titled “Flow cytometry.” This sentence should read: 2), PE-Cy5-conjugated anti-TCRβ (BioLegend, San Diego, CA), PE-Cy7-conjugated ant-NK1.1 (BioLegend), PE-Cy7-conjugated anti-CD8a (BioLegend), PE-CF594-conjugated anti-CD4 (BD Biosciences), and GPR30 (N15)-R Antibody (Santa Cruz Biotechnology...

We calculate the O(αs) corrections to the charged Higgs mediated inclusive semi-tauonic B decay. By working in the Landau gauge, we demonstrate how to obtain the charged Higgs contributions (both direct and interference terms) from the known QCD corrections to t → bH+. Combining our results with O(1/mb) corrections to the spectator model and comparing the theoretical prediction with the recent ...

Triatoma jatai sp. nov. is the first new species of triatomine to be described in the state of Tocantins, in the northern region of Brazil. It was caught on rock outcrops in the wild environment and, more recently, invading homes. While T. jatai sp. nov. is morphologically similar to Triatoma costalimai, it is distinguished by its general colouring, differences in the blotches on the connexivum...

This paper presents, from the perspective of technological development and production, the results of an investigation examining 61 clinical studies with vaccines conducted in Brazil between 1938-2013, with the participation of the Oswaldo Cruz Institute (IOC) and the Oswaldo Cruz Foundation (Fiocruz). These studies have been identified and reviewed according to criteria, such as the kind of va...
