Nucella lapillus L. imposex levels after legislation prohibiting TBT antifoulan...

Nucella lapillus (dog whelk) imposex levels were assessed along the mainland Portuguese coast in 2006 and 2008 and were compared with available data from 2003 for the same area. Given that specimen size has been described as a factor inducing variation in some of the imposex assessment indices, and thus resulting in less reliable results, new monitoring and data analysis procedures are described and applied to ...

Biological upgrading of wastes from the pulp and paper industry

A process for biological upgrading of recycled paper sludge (RPS) was developed based on the enzymatic hydrolysis of major sludge components (cellulose and xylan) with commercial enzymes and fermentation of the resulting sugars into ethanol or lactic acid with adequate microbial strains. The process was implemented performing both steps sequentially (SHF) or simultaneously (SSF). Cellulosic and hemicellulosic f...

Neonatal bronchoscopy: a retrospective analysis of 67 cases and a review of the...

The availability of newer, more sophisticated and versatile bronchoscopes has expanded the spectrum and scope of the indications for bronchoscopy in the newborn infant both for diagnostic and therapeutic purposes. The aim of this study was to carry out a retrospective analysis of the bronchoscopies performed on newborn infants, and to review the indications of this procedure in this age group. Sixty-three patie...

Optimization study of Escherichia coli TB1 cell disruption for cytochrome b5 re...

The recovery of a recombinant intracellular protein, cytochrome b5, from Escherichia coli TB1 cells was carried out by bead mill disintegration in a discontinuous smallscale instrument. This process was optimized by the use of experimental factorial design. Several parameters were studied: operating time, amount and size of beads, cellular suspension concentration, and presence of toluene and lysozyme. For the ...

The rare metastasis of osteosarcoma of a long bone associated with von Reckling...

We report a case of femoral osteosarcoma with brain metastases in a female patient with longstanding von Recklinghausen disease. Osteosarcoma of a long bone has not yet, to our best knowledge, been reported in association with type I Neurofibromatosis. Central nervous system metastases occur very rarely in osteosarcoma. ; We report a case of femoral osteosarcoma with brain metastases in a female patient with l...
