BACKGROUND Pediatric inflammatory bowel disease (IBD) is challenging to diagnose because of the non-specificity of symptoms; an unequivocal diagnosis can only be made using colonoscopy, which clinicians are reluctant to recommend for children. Diagnosis of pediatric IBD is therefore frequently delayed, leading to inappropriate treatment plans and poor outcomes. We investigated the use of 16S rR...
1. To test by comparison with other sites drilled during this expedition whether microbial communities, activity, and survival strategies are different in this deeply buried, organic-poor environment than those in open-ocean sediments with more organic matter or shallower burial and 2. To examine how hydrologic flow in the underlying basement affects microbial communities, microbial activities,...
Atmospheric nitrogen (N) deposition is changing in both load quantity and chemical composition. The load effects have been studied extensively, whereas the composition effects remain poorly understood. We conducted a microcosm experiment to study how N chemistry affected the soil microbial community composition characterized by phospholipid fatty acids (PLFAs) and activity indicated by microbia...
Microbial toxicity of test substances in tetrazolium assay is often quantified while referring to their IC50 values. However, the implication such an estimate very limited and can differ across studies depending on prevailing conditions. In this work, a factorial design-based end-point microbial was performed, which suggests significant interaction (P= 0.041) between inoculum dose formazan prod...
A decision making tool is proposed to evaluate assembly costs of microproducts (< 1 dm) and to compare different assembly strategies for a given product or product family. The tool takes into account equipment costs as well as running costs, for manual and automatic assembly. Its specificity lies in its ability to deal with different production mixes and production volumes over the life cycle o...
PURPOSE To determine by bacterioscopy and culture the microorganisms carried by corneal foreign body and their sensitivity to antibiotics by antibiotic sensitivity test. METHODS A prospective study was carried out and information was collected on 101 patients who presented with corneal foreign body at the São Paulo Hospital Eye Emergency Service. Prior to any treatment, a sample of the ipsila...
