Riquelme, Gloria; Stutzin Schottlander, Andrés; Barros, Luis Felipe; Liberona Leppe, José (Mosby-Year book, 1995)OBJECTIVE: Ion channels play important roles in epithelial transport, but they are difficult to access for conventional electrophysiologic studies in intact placenta. The purpose of this work was to explore the suitability ...

Riquelme, Gloria; De Gregorio, Nicole; Vallejos, Catalina; Berrios, Macarena; Morales, Bárbara (2012)Potassium channels play important physiological roles in human syncytiotrophoblasts (hSTBs) from placenta, an epithelium responsible for maternal-fetal exchange. Basal and apical plasma membranes differ in their lipid and ...

Wyneken, Ursula; Riquelme, Gloria; Villanueva, Sergio; Orrego, Fernando (Elsevier Ireland Ltd, 1997)Postsynaptic densities (PSDs) were isolated from rat brain cortex and hippocampus, purified and incorporated into giant (5-80 μm in diameter) liposomes. Gigaohm seals were obtained with a patch-clamp pipette, and a giant ...

Jiménez, Verónica; Henríquez, Mauricio; Galanti Garrone, Norbel; Riquelme, Gloria (2011)Potassium channels (K+ channels) are members of one of the largest and most diverse families of membrane proteins, widely described from bacteria to humans. Their functions include voltage-membrane potential maintenance, ...

Errasti-Murugarren, Ekaitz; Diaz, Paula; Godoy, Valeria; Riquelme, Gloria; Pastor-Anglada, Marçal (2011)The plasma membrane distribution and related biological activity of nucleoside transporter proteins (NTs) were investigated in human syncytiotrophoblast from term placenta using a variety of approaches, including nucleoside ...

Riquelme, Gloria; Jaimovich Pérez, Enrique; Lingsch, Carlota; Behn Thiele, Claus (1982)Chemically induced shape changes of the human erythrocyte may result from cell membrane bending by surface tension changes at the lipid bilayer (Evans, E.A. (1947) Biophys. J. 14, 923-931) implicating differential expansion ...

Riquelme, Gloria; Díaz, Mario; Sepúlveda, Francisco V. (1997)We have studied the effect of intracellular pH (pH(i)) shifts on the activity of Ca2+-dependent, inwardly rectifying K+ channels of HeLa cells. Recordings of macroscopic currents in symmetrical 145 mM K+ and internal pH ...

Llanos Vidal, Paola; Henríquez, Mauricio; Minic, Jasmina; Elmorjani, Khalil; Marion, Didier; Riquelme, Gloria; Molgó, Jordi; Benoit, Evelyne (2006)Puroindoline-a (PIN-a) and α1-purothionin (α1-PTH), isolated from wheat endosperm of Triticum aestivum sp., have been suggested to play a role in plant defence mechanisms against phytopathogenic organisms. We investigated ...

Hidalgo Tapia, María Cecilia; Lecocq Parra, Claudio; Riquelme, Gloria; Jaimovich Pérez, Enrique (1986)Transverse tubule vesicles were isolated from frog skeletal muscle by a procedure initially described by Rosemblatt (J. Biol. Chem. 256, 8140-8148 (1981)) and later modified by Hidalgo (J. Biol. Chem. 258, 13937-13945 ...
