Lipopeptide production by Bacillus subtilis R1 and its possible applications

Braz. j. microbiol; 47 (4), 2016
Abstract The possible application of a bacterial strain - Bacillus subtilis R1, isolated from an oil contaminated desert site in India, as biocontrol agent and its biosurfactant in microbial enhanced oil recovery are discussed. The biosurfactant production in minimal medium was carried out at different t...

Endocarditis infecciosa por Abiotrophia defectiva diagnosticada por espectrometría de masas (MALDI-TOF MS) en Argentina

Rev. chil. infectol; 33 (6), 2016
We report the case of a 63-year-old woman with congestive heart failure due to a bicuspid aortic valve and severe aortic stenosis. The patient had a febrile syndrome with positive blood cultures for Abiotrophia defectiva, Transesophageal echocardiogram revealed the presence of paravalvular abscess, which...

Osteomielitis crónica por Corynebacterium striatum en una adolescente

Rev. chil. infectol; 33 (6), 2016
A case of a girl with chronic posttraumatic osteomyelitis of the right tibia with microbiological isolation of Bacillus spp. by conventional methods and confirmation by mass spectrometry MALDI-TOF (matrix-assisted laser desorption/ionization time-of-flight mass) of Corynebacterium striatum is presented. ...

Matrix Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry for identification of Clostridium species isolated from Saudi Arabia

Braz. j. microbiol; 47 (2), 2016
Abstract The aim of this study was to identify different Clostridium spp. isolated from currency notes from the Ha’il region of Saudi Arabia in September 2014 using MALDI–TOF-MS. Clostridium spp. were identified by Bruker MALDI–TOF-MS and compared with VITEK 2. The confirmation of the p...

Análise in situ de proteínas diferencialmente expressas em carcinomas epidermoides penianos por espectrometria de massas utilizando Matrix-Assisted Laser Desorption/Ionization (MALDI)

O carcinoma de pênis (CaPe) corresponde a uma doença maligna mutilante do homem. É mais frequente em regiões economicamente desprivilegiadas, como o Norte/Nordeste do Brasil, onde frequentemente é diagnosticado como doença mais avançada. Assim, novos marcadores diagnósticos, prognósticos e predi...

Evaluación de la espectrometría de masas: MALDI-TOF MS para la identificación rápida y confiable de levaduras
Evaluation of mass spectrometry: MALDI-TOF MS for fast and reliable yeast identification

Rev. argent. microbiol; 47 (2), 2015
La espectrometría de masas, conocida como matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), es una técnica utilizada en la identificación de microorganismos mediante la creación de un espectro basado en el perfil de proteínas, que es único para una especie...

Metodología de pre-procesamiento de datos adquiridos por MALDI-MSI en muestras de tejidos
Pre-processing methodology of acquired data by MALDI-MSI in tissue samples

En la última década, la Imagenología por Espectrometría de Masas MALDI (MALDI-MSI) ha demostrado su potencial en el campo de la proteómica. Debido a la alta dimensionalidad de los conjuntos de datos obtenidos en los experimentos de MADI-MSI y las variabilidades inherentes al proceso de adquisición,...

Proteomic analysis of the regenerating liver following 2/3 partial hepatectomy in rats

Biol. Res; 47 (), 2014
BACKGROUND: Liver regeneration (LR) after 2/3 partial hepatectomy (PH) is one of the most studied models of cell, organ, and tissue regeneration. Although the transcriptional profile analysis of regenerating liver has been carried out by many reserachers, the dynamic protein expression profile during LR ...

Synthesis and MALDI-ToF characterization of dendronized poly(ethylene glycol)s

Braz. j. pharm. sci; 49 (spe), 2013
Well-defined hybrids of linear poly(ethylene glycol)s (PEGs) and dendritic polyesters were prepared via the dendronization of the alcohol end groups of the mono and difunctional linear PEGs. Though useful for rudimentary product characterization, GPC and NMR could not verify the overall structural purity...
