BACKGROUND/AIMS Endorectal endoscopic ultrasound (EUS) can provide accurate and reliable information for initial staging of locally advanced rectal cancer (LARC) in both the depth of rectal cancer penetration (T-stage) and regional lymph node involvement (N-stage). However, there is still no consensus about its accuracy in retagging LARC after neoadjuvant(More)
The ability of microorganisms to sense and respond to sudden changes in their environment is often based on regulatory systems comprising reversible protein phosphorylation. The archaellum (former: archaeal flagellum) is used for motility in Archaea and therefore functionally analogous to the bacterial flagellum. In contrast with archaellum-mediated(More)
Microbial fuel cells (MFCs) recover energy sustainably in wastewater treatment. Performance of non-noble cathode catalysts with low cost in neutral medium is vital for stable power generation. Nitrogen-doped graphene (NG) as cathode catalyst was observed to exhibit high and durable activity at buffered pH 7.0 during electrochemical measurements and in MFCs(More)
RV Armored RNA constructed in the laboratory was shown to be resistant to RNase and DNase digestion. It could remain stable at 4 °C for at least 60 days, and was much more stable than RV strain JR23 in normal human plasma. Therefore it could be used as stable, well-characterized positive control and standard for quantitative RT-PCR assay.
The majority of Crenarchaeota utilize the cell division system (Cdv) to divide. This system consists of three highly conserved genes, cdvA, cdvB and cdvC that are organized in an operon. CdvC is homologous to the AAA-type ATPase Vps4, involved in multivesicular body biogenesis in eukaryotes. CdvA is a unique archaeal protein that interacts with the(More)
Multidrug resistance (MDR) transporters are capable of secreting structurally and functionally unrelated toxic compounds from the cell. Among this group are ATP-binding cassette (ABC) transporters. These membrane proteins are typically arranged as either hetero- or homo-dimers of ABC half-transporters with each subunit consisting of a membrane domain fused(More)
