Publication Type: Peer reviewed scientific article Authors: Eveline Verleysen; Thorsten Wagner; Hans-Gerd Lipinski; Ralf Kägi; Robert Koeber; Ana Boix-Sanfeliu; Pieter-Jan De Temmerman; Jan Mast Source: Materials, Volume 12, Issue 14 (2019) Keywords: elec ...
Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution
agents (alumina, sodium or potassium in combination with phosphate). Particle size analyses, by TEM, SEM, XDC or DC, have been carried out on five commercial brands of anatase E 171 and one of rutile E 171 ...

Establishing mono-eukaryotic Histomonas meleagridis cultures from in vivo infection contaminated with Tetratrichomonas gallinarum and Blastocystis spp.
Additionally, TEM examination and analysis by PCR amplification of the small subunit rRNA gene could exclude the co-cultivation of T. gallinarum and Blastocystis spp. Furthermore, after successful propagation and ...
Quantitative characterization of agglomerates and aggregates of pyrogenic and precipitated amorphous silica nanomaterials by transmission electron microscopy.
and agglomerates. A method based on transmission electron microscopy (TEM), to visualize the NM and on image analysis, to measure detected features quantitatively, was assessed for its capacity to ...
Determination of the volume-specific surface area by using transmission electron tomography for characterization and definition of nanomaterials.
electron microscopy (TEM) remains an important technique to investigate the size, shape and surface characteristics of particles at the nanometer scale. Resulting micrographs are two dimensional projections ...
Trends in production of extended-spectrum beta-lactamases among Enterobacteriaceae of clinical interest: results of a nationwide survey in Belgian hospitals.
Escherichia coli (49%), Enterobacter aerogenes (32%) and Klebsiella pneumoniae (9%) represented the most prevalent species. Isolates harboured predominantly TEM-24 (30.7%), CTX-M-15 (24.2%) and TEM-52 (12.1%). ...
Electron tomography of negatively stained complex viruses: application in their diagnosis.
is inherent to TEM. In selected examples, such analyses can improve diagnosis of viral agents. Health Topics: Animal health Santé animale Diergezondheid Manuscript versions: DOI: ...
Novel insertion sequence- and transposon-mediated genetic rearrangements in genomic island SGI1 of Salmonella enterica serovar Kentucky36800
the beta-lactamase bla(TEM-1) gene flanked by two IS26 elements in opposite orientations. The rightmost IS26 element was shown to be inserted into the S044 open reading frame of the SGI1 backbone. This ...
Dissemination of an extended-spectrum-beta-lactamase blaTEM-52 gene-carrying IncI1 plasmid in various Salmonella enterica serovars isolated from poultry and humans in Belgium and France between 2001 and 200536778
IM Time Factors Abstract: We report here the dissemination of a conjugative IncI1 plasmid carrying bla(TEM-52) on a Tn3 transposon conferring resistance to extended-spectrum cephalosporins in ...
