Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling

strands to be sequenced preferably. The combination of metagenomics and adaptive sampling could allow to circumvent the isolation but also the enrichment of the food sample. Materials and Methods As ...

Safety assessment of titanium dioxide (E171) as a food additive.

With respect to genotoxicity, the Panel concluded that TiO particles have the potential to induce DNA strand breaks and chromosomal damage, but not gene mutations. No clear correlation was observed ...

effects. With respect to genotoxicity, the Panel concluded that TiO2 particles have the potential to induce DNA strand breaks and chromosomal damage, but not gene mutations. No clear correlation was observed ...

Increased surface area of halloysite nanotubes due to surface modification predicts lung inflammation and acute phase response after pulmonary exposure in mice

by the alkaline comet assay as DNA strand breaks in BAL cells, lung and liver tissue. The etched HNT (NN-etched) had 4–5 times larger BET surface area than the unmodified HNT (NN). Instillation of ...

Toxoplasma gondii in stranded marine mammals from the North Sea and Eastern Atlantic Ocean: Findings and diagnostic difficulties

Toxoplasma gondii in marine mammals remains a poorly understood phenomenon. In this study, samples from 589 marine mammal species and 34 European otters (Lutra lutra), stranded on the coasts of Scotland, ...

Small RNA deep sequencing identifies viral microRNAs during malignant catarrhal fever induced by alcelaphine herpesvirus 1.

a lymphoblastoid cell line propagated from a calf infected with AlHV-1 and developing MCF. Among the sequenced candidate miRNAs, 32 were expressed on the reverse strand of the genome in two main clusters. The ...

Study of the virulence of serotypes 4 and 9 of African horse sickness virus in IFNAR(-/-), Balb/C and 129 Sv/Ev mice.

Interferon-alpha mice Mice, Inbred BALB C Mice, Knockout Receptor, Interferon alpha-beta RNA, Double-Stranded Serogroup virulence Abstract: African horse sickness virus (AHSV) is a double-stranded RNA virus which ...

Development of giant bacteriophage phiKZ is independent of the host transcription apparatus

strand of the genome. Early transcription does not require phage or host protein synthesis. Transcription of middle and late genes is dependent on protein synthesis and mediated by poorly conserved middle ...

Belgian recommendations on ANA, anti-dsDNA and anti-ENA antibody testing704

nuclear antigens, i.e. antinuclear antibodies (ANA), antibodies to double-stranded DNA (dsDNA) and extractable nuclear antigens (ENA), are useful as diagnostic markers for a variety of autoimmune diseases. ...
