Rojas, Eduardo; Vergara, Víctor; Soto Bertrán, Rodrigo (Elsevier Ltd, 2019)A discrete element method is designed to evaluate the relative wear on hoppers caused by friction during operation in an open-pit mine. The results of the model show good agreement with measurements on real industrial ...

Luxoro Mariani, Mario; Nassar-Gentina, Verónica; Rojas, Eduardo (1997)We report here that exposing cultured chromaffin cells to a low ionic strength medium (with sucrose in place of NaCl to maintain osmolarity) can induce a marked elevation in cytosolic Ca 2+ concentration ([Ca 2+](i)) and ...
-
Rojas, Eduardo; Hidalgo Tapia, María Cecilia (1968)Labelled Ca `,+ were incorporated into giant axons froln the squid Dosidicus gigas by immersing them in sea water containing 4'5Ca'-' ~. The washout technique was used and two kinetics for 4SCa2+ outflow were demonstrated ...

Barrera Arriagada, Christian Felipe; Astorga, César; Atwater, Illani; Rojas, Eduardo; Mears, David; Caviedes, Raúl; Caviedes, Pablo (2007)The CNh and CTb cell lines are derived from the cerebral cortex of normal and trisomy 16 mice, an animal model of human trisomy 21, Down syndrome (DS), and represent in vitro models to study cellular events associated with ...

He, Li Ping; Mears, David; Atwater, Illani; Rojas, Eduardo; Cleemann, Lars (2003)1 We have investigated the effects of loperamide on intracellular Ca2+ stores and membrane K+ channels in insulin-secreting hamster insulinoma (HIT-T15) cells. 2 In cell-attached patch-clamp mode, loperamide (3 – 250 mM) ...

Santis, Marcella; Rojas, Eduardo (1969)The main purpose of this work has been to study further the association of cations and anions with cell membrane lipids, in particular with phosphatidylcholine. The adsorption of Ca2+ or SO4 2- to phosphatidylcholine ...

Mears, David; Rojas, Eduardo (Society of Biology of Chile, 2006)We used the single-microelectrode voltage-clamp technique to record ionic currents from pancreatic β-cells within intact mouse islets of Langerhans at 37C, the typical preparation for studies of glucose-induced "bursting" ...
-
Rojas, Eduardo; Soto Bertrán, Rodrigo; Clement, Eric; Trulsson, Martin; Andreotti, Bruno (EDP Sciences, 2017)A numerical model of granular material at different packing fractions and under steady shear is submitted to a sudden shear reversal. We monitor consequences of the strong density and shear rate spatiotemporal heterogeneities, ...

Mears, David; Zimliki, Charles L.; Atwater, Illani; Rojas, Eduardo; Glassman, Mirta; Leighton, Ximena; Pollard, Harvey B.; Srivastava, Meera (2012)Insulin secretion from the pancreatic β-cell is controlled by changes in membrane potential and intracellular Ca2+. The contribution of intracellular Ca2+ stores to this process is poorly understood. We have previously ...
