Influencia del tipo de registro (unipolar o bipolar) en las características espectrales de los registros epicárdicos de la fibrilación ventricular. E…
2007
Introduction and objectives. The aim of this study was to examine the hypothesis that the recording mode (ie, unipolar or bipolar) affects the information obtained using spectral analysis techniques during ventricular fibrillation by carrying out an experiment using epicardial electrodes. Methods. Recordings of ventricular fibrillation were obtained in 29 isolated rabbit hearts using a multipleelectrode probe located on the left ventricular free wall. The parameter values obtained in the frequency domain (by Fourier analysis) using unipolar or bipolar electrodes, different interelectrode distances, and different orientations (ie, horizontal, vertical, or diagonal) were compared. Results. Ch…

Possible Roles of Mannoproteins in the Construction of Candida Albicans Cell Wall
1993
The shape of Candida albicans cells depends on their cell walls and some of their mannoproteins may act as modulators of the final molecular architecture. If that were the case, the wall mannoproteins might form part of what could be called a “morphogenetic code”.
Role of biomarkers in monitoring antiblastic cardiotoxicity
2016
Early detection of anticancer drug-induced cardiotoxicity (CTX) has been evaluated by most international scientific cardiology and oncology societies. High expectations have been placed on the use of specific biomarkers. In recent years, conventional biomarkers and molecules of more recent interest have been tested and compared in the context of anticancer drug-related CTX. Encouraging results were obtained from studies on molecules of myocardial damage, such as troponin and markers of myocardial wall stress, including circulating natriuretic peptides, as well as from the assessment of the products of inflammation or circulating levels of free radicals. However, clear guidelines on their se…
Operazioni di pagamento tramite wallet e responsabilità da omessa applicazione della strong customer authentication
2022
Lo scritto commenta una recente decisione del Collegio di Coordinamento ABF a proposito del riparto di responsabilità tra intermediario emittente una carta di pagamento e cliente, in caso di operazioni abusivamente realizzate da terzi tramite «wallet». Il Collegio, analizzando la disciplina in tema di servizi di pagamento elettronici e di « Strong Customer Authentication », precisa come l’indagine del caso vada in primo luogo condotta verificando che l’intermediario abbia fornito la prova della corretta applicazione dell’autenticazione forte in ogni fase delle transazioni abusivamente compiute. Ove tale prova non sia fornita, egli dovrà restituire quanto dal cliente abusivamente versato. Th…
α-L-rhamnosidases: Old and New Insights
2007
L-Rhamnose is a component of plant cell wall pectic polysaccharides (Mutter et al., 1994; Ridley et al., 2001), glycoproteins (Haruko and Haruko, 1999) and secondary metabolites such as anthocyanins (Renault et al., 1997), flavonoids (Bar-Peled et al., 1991) and triterpenoids (Friedman and McDonald, 1997). It has also been found in bacterial heteropolysaccharides (Hashimoto and Murata, 1998), rhamnolipids (Ochsner et al., 1994) and in the repeating units of the O-antigen structure of the lipopolysaccharide component of bacterial outer membranes (Chua et al., 1999). Some rhamnosides are important bioactive compounds, e.g. cytotoxic saponins (Bader et al., 1998; Yu et al., 2002), antifungal p…
Patterns of wall synthesis inSaccharomyces cerevisiae
1979
Wall formation inSaccharomyces cerevisiae seems to be the result of two main patterns of wall material deposition: (i) around the whole periphery of the cell in nonbudding ones, and (ii) mainly at the tip of the daughter cell or at the cross wall that separates dividing cells. This interpretation has been obtained following experiments in which RNA or protein synthesis has been inhibited. Under these conditions, glucan formation takes place, and wall thickening is probably due to the accumulation of this polysaccharide. Furthermore, once a pattern of wall deposition has been established, it is not modified by inhibition of RNA or protein synthesis.
Relationships Between Dimorphism, Cell Wall Structure, and Surface Activities in Candida albicans
1991
Most cells are covered with a complex network of interacting molecules that form the extracellular matrix. These molecules (proteins and polysaccharides) are secreted locally and interact among themselves to form an organized structure outside the cell plasma membrane. In unicellular eukaryotic organisms and plant cells, this structure is reinforced to withstand osmotic changes in the external environment, giving rise to the so-called cell wall.
Role of glycosylation in the incorporation of intrinsic mannoproteins into cell walls of Saccharomyces cerevisiae.
1989
Cell wall mannoproteins from Saccharomyces cerevisiae are completely or partially incorporated into their final location when N-glycosylation is inhibited by tunicamycin. These include a 90–100 kDa species still containing O-linked oligomannose chains, derived from a N-glycosylated material larger than 120 kDa; and a 30.5 kDa peptide lacking mannose residues, derived from a 33 kDa species. For both species, the growth temperature influences the level of incorporation of the non N-glycosylated molecules. Secretion of the peptides lacking N-linked saccharide chains follows the route defined by sec mutants.
