ABSTRACT Outer membrane vesicles (OMVs) from Gram-negative bacteria are known to be involved in lateral DNA transfer, but the presence of these has remained difficult explain. An ultrastructural study Antarctic psychrotolerant bacterium Shewanella vesiculosa M7 T revealed that this naturally releases conventional one-bilayer OMVs through a process which outer is exfoliated and only periplasm entrapped, together with more complex type OMV, previously undescribed, on formation drag along inner...

Abstract Historically, most of the nautiloids arisen during Early Jurassic have been assigned initially to genus NautilusLinnaeus, 1758, and subsequently CenocerasHyatt, 1884. At present, a tendency rehabilitate other genera or describe new ones predominates among few authors who try classify group these problematic cephalopods. In present work, Ligeiceras has described for remarkably small involute with notably retrogressive suture lines. It smooth slightly ornamented external surface,...

Although evaluation tumour biopsy material the gold standard EGFRmutation testing, this approach remains challenging due to invasiveness procedure and intra-tumour heterogeneity. Mutation detection in circulating cell-free DNA can overcome these caveats also be used tracking dynamics Methods: Fifty-six plasma samples from 19 mutant NSCLC patients...
