Endocarditis due to Trichosporon beigelii 11 years after mitral valve replacement.

Trichosporon beigelii is a non-pathogenic fungus that can however become an opportunist agent of disseminating and potentially fatal infections, especially in immunocompromised patients. In the literature, there are only 11 published cases of infective endocarditis due to T. beigelii.

Characterization of a new Acidobacteria-derived moderately thermostable lipase from a Brazilian Atlantic Forest soil metagenome.

A clone (LP001) expressing a new lipase gene was isolated from a metagenomic library of the Brazilian Atlantic Forest soil. The DNA insert of LP001 was fully sequenced, and 38 ORFs were identified. Comparison of ORFs, %G + C content and gene organization with sequenced bacterial genomes suggested that the fosmid DNA insert belongs to an organism of the Acidobacteria phylum.

Identification and characterization of a new true lipase isolated through metagenomic approach.

Background: Metagenomics, the application of molecular genomics to consortia of non-cultivated microbes, has the potential to have a substantial impact on the search for novel industrial enzymes such as esterases (carboxyl ester hydrolases, EC 3.1.1.

[Agenesis of the right superior vena cava associated with total heart block].

The superior left vena cava with the absent superior vena cava is a rare abnormality, especially when associated with total heart block. We report a case of a patient in which the presence of superior left vena cava and the absence of the superior vena cava was detected during the implantation of a pacemaker for the correction of a total heart block, which led us to use a different technique for the fixation of the ventricular electrode. To confirm the supposed absence, several image exams were made showing the difficulty on the diagnosis of the described syndrome.

Spontaneous coronary dissection: case report.

The purpose of the paper is to demonstrate the case of a 62-year-old man, with spontaneous coronary dissection of the left circumflex artery, treated surgically by myocardial revascularization. The successfully accomplished surgery demonstrates, in this case, to be the only possible way of a cure.

Purification and characterization of the bifunctional uridylyltransferase and the signal transducing proteins GlnB and GlnK from Herbaspirillum seropedicae.

GlnD is a bifunctional uridylyltransferase/uridylyl-removing enzyme that has a central role in the general nitrogen regulatory system NTR. In enterobacteria, GlnD uridylylates the PII proteins GlnB and GlnK under low levels of fixed nitrogen or ammonium. Under high ammonium levels, GlnD removes UMP from these proteins (deuridylylation).
