The protein expression profiles and antigenicities of both culture filtrates (CF) and cellular extracts (CE) of Mycobacterium paratuberculosis were compared by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), one-dimensional electrophoresis (1-DE) and 2-DE immunoblotting, and enzyme-linked immunosorbent assay (ELISA). The CF proteins were harvested from supernatants of stat...

The reactivity of a series of organometallic rare earth and actinide complexes with hemilabile NHC-ligands towards substrates with acidic C-H and N-H bonds is described. The synthesis, characterisation and X-ray structures of the new heteroleptic mono- and bis(NHC) cyclopentadienyl complexes LnCp2(L) 1 (Ln = Sc, Y, Ce; L = alkoxy-tethered carbene [OCMe2CH2(1-C{NCHCHN(i)Pr})]), LnCp(L)2 (Ln = Y)...

Reaction of the rodent carcinogen acrylonitrile (AN) at pH 7.0 for 10 and/or 40 days with 2'-deoxyadenosine (dAdo), 2'-deoxycytidine (dCyd), 2'-deoxyguanosine (dGuo), 2'-deoxyinosine (dIno), and thymidine (dThd) resulted in the formation of cyanoethyl and carboxyethyl adducts. The adducts isolated were 1-(2-carboxyethyl)-dAdo (1-CE-dAdo), N6-CE-dAdo, 3-CE-dCyd, 7-(2-cyanoethyl)-Gua (7-CNE-Gua),...

This paper proves that a connected matroid M in which a largest circuit and a largest cocircuit have c and c∗ elements, respectively, has at most 1 2 cc∗ elements. It is also shown that if e is an element of M and ce and ce are the sizes of a largest circuit containing e and a largest cocircuit containing e, then |E(M)| ≤ (ce−1)(ce−1)+1. Both these bounds are sharp and the first is proved using...

The redox potential (E) of the couple Ce 4 + /Ce 3 + has been determined up to 368 K by means of cyclic voltammetric measurement in aqueous H C 1 0 4 solutions with cHC104 decreasing from 7.45 to 0.023 mol kg" 1 . A constant potential of (1.741 V)2 9 8 K , resp. (1.836 V) 3 6 8 K , indicating the existence of pure unhydrolysed Ce 4 + was obtained at c H c l 0 4 > 6.05 m. At lower HC10 4 concent...

OBJECTIVES This study compares the long-term performance of the Carpentier-Edwards (CE) porcine bioprosthesis and the CE pericardial bioprosthesis for aortic valve replacement (AVR). BACKGROUND With new bioprostheses on the horizon, there is renewed interest in how the long-term durability of current pericardial bioprostheses compares with the traditional porcine bioprosthesis. METHODS We r...

Capillary electrophoresis–electrospray ionization-mass spectrometry (CE-ESI-MS) has emerged as a powerful tool for the analysis of charged compounds in biological samples [1–3]. CE–MS can be used for the characterization of a wide variety of analytes, e.g., metabolites, peptides, glycans and intact proteins [4–6]. So far, the co-axial sheath–liquid interface has been primarily used for the coup...

Résumé. Ce papier présente une nouvelle approche de cartographie des connaissances stratégique/métiers guidée par apprentissage automatique en vue de définir la stratégie de gestion des connaissances à engager. La démarche que nous avons expérimentée s’appuie sur une nouvelle méthode cellulaire d’extraction de règles à partir des données nommée CASI (Cellular Automaton for Symbolic Induction). ...
