Development of Clostridium difficile R20291ΔPaLoc model strains and in vitro methodologies reveals CdtR is required for the production of CDT to cytotoxic levels [PDF]
, 2017 Assessing the regulation of Clostridium difficile transferase (CDT), is complicated by the presence of a Pathogenicity locus (PaLoc) which encodes Toxins A and B. Here we developed R20291ΔPaLoc model strains and cell-based assays to quantify CDT-mediated

Current-mode universal filter and quadrature oscillator using CDTAs
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2014 A current dierencing transconductance amplier (CDTA)-based multiple-input single-output (MISO) current- mode universal lter and a quadrature oscillator (QO) are presented in this paper. The same circuit is used in the lter and oscillator, which only consists of 2 CDTAs and 2 capacitors.

Journal of the Brazilian Chemical Society, 2006 It was investigated the kinetic of the reduction reaction of tris(oxalate)cobaltate by L-ascorbic acid, H2A, at different acidity. The Co(III) complex was monitored at 600 nm, under pseudo-first-order conditions: [H2A] = 3.0 x 10-2 mol L-1, [Co(C2O4)3]3-

Detection of the ADP-ribosyltransferase toxin gene (cdtA) and its activity in Clostridium difficile isolates from Equidae [PDF]
, 2017 Clostridium difficile is an antibiotic-associated emerging pathogen of humans and animals. Thus far three toxins of C. difficile have been described: an enterotoxin (ToxA), a cytotoxin (ToxB) and an ADP-ribosyltransferase (CDT).
