    • A "minimal" sodium channel construct consisting of ligated S5-P-S6 segments forms a toxin-activatable ionophore 
      Chen, Zhenhui; Alcayaga, Carmen; Suárez Isla, Benjamín; O'Rourke, Brian; Tomaselli, Gordon; Marbán, Eduardo (2002)
      The large size (six membrane-spanning repeats in each of four domains) and asymmetric architecture of the voltage-dependent Na+ channel has hindered determination of its structure. With the goal of determining the minimum ...
    • Activation of calcium channels in sarcoplasmic reticulum from frog muscle by nanomolar concentrations of ryanodine 
      Bull, Alan; Marengo, Juan José; Suárez Isla, Benjamín; Donoso P., Gonzalo; Sutko, J. L.; Hidalgo Tapia, María Cecilia (1989)
      Sarcoplasmic reticulum vesicles isolated from fast-twitch frog skeletal muscle presented two classes of binding sites for ryanodine, one of high affinity (Kd1 = 1.7 nM, Bmax1 = 3.3 pmol per mg) and a second class with lower ...
    • Comparison of AOAC 2005.06 LC official method with other methodologies for the quantitation of paralytic ... 
      Turner, Andrew D.; Hatfield, Robert G.; Rapkova, Monika; Higman, Wendy; Algoet, Myriam; Suárez Isla, Benjamín; Córdova, Marco; Cáceres, Catherine; Riet, Jeffrey van de; Gibbs, Ryan; Thomas, Krista; Quilliam, Michael A.; Lees, David N. (Springer, 2011)
      A refined version of the pre-column oxidation liquid chromatography with fluorescence detection (ox-LCFLD) official method AOAC 2005.06 was developed in the UK and validated for the determination of paralytic shellfish ...
    • Contrasting Physiological Responses of Two Populations of the Razor Clam Tagelus dombeii with Different ... 
      Navarro, Jorge M.; González, Katerina; Cisternas, Bárbara; López Contreras, Jorge; Chaparro, Óscar R.; Segura, Cristian J.; Córdova, Marco; Suárez Isla, Benjamín; Fernández Reiriz, María J.; Labarta, Uxio (PLOS One, 2014)
      This study describes the physiological performance of two populations of the razor clam Tagelus dombeii from two geographic areas with different histories of exposure to paralytic shellfish poisoning (PSP) linked to the ...
    • Desarrollo de un sistema de trazabilidad para mitílidos de cultivos en Chile 
      Arriagada Acevedo, Gabriel Alejandro (Universidad de Chile, 2006)
      El cultivo de mitílidos en Chile ha experimentado un fuerte crecimiento en sus exportaciones en los últimos 15 años, transformándose en la segunda actividad acuícola de mayor importancia en el país, luego de los salmones. ...
    • Functionally heterogenous ryanodine receptors in avian cerebellum 
      Sierralta, Jimena; Fill, Michael; Suárez Isla, Benjamín (1996)
      The functional heterogeneity of the ryanodine receptor (RyR) channels in avian cerebellum was defined. Heavy endoplasmic reticulum microsomes had significant levels of ryanodine and inositol 1,4,5-trisphosphate binding. ...
    • Identification and characterization of potentially algal-lytic marine bacteria strongly associated with the ... 
      Amaro, Ana M.; Fuentes, María S.; Ogalde, Sandra R.; Venegas, Juan A.; Suárez Isla, Benjamín (2005)
      The toxic dinoflagellate Alexandrium catenella isolated from fjords in Southern Chile produces several analogues of saxitoxin and has been associated with outbreaks of paralytic shellfish poisoning. Three bacterial strains, ...
    • Investigations into matrix components affecting the performance of the official bioassay reference method ... 
      Turner, Andrew D.; Dhanji-Rapkova, Monika; Algoet, Myriam; Suárez Isla, Benjamín; Córdova, Marco; Cáceres, Catherine; Murphy, Cory J.; Casey, Melanie; Lees, David N. (Elsevier, 2012)
      Significant differences previously observed in the determination of paralytic shellfish poisoning toxins (PSTs) in oysters using official method AOAC 2005.06 and 959.08 were investigated in detail with regard to possible ...
    • Modal gating in neuronal and skeletal muscle ryanodine-sensitive Ca2+ release channels 
      Armisen Yáñez, Ricardo; Sierralta, J.; Vélez, P.; Naranjo, D.; Suárez Isla, Benjamín (1996)
      The bursting behavior of ryanodine-sensitive single Ca2+ release channels present in chicken cerebellum endoplasmic reticulum (ER), rat hippocampus ER, and frog and rabbit skeletal muscle sarcoplasmic reticulum was ...
    • A Roadmap for Hazard Monitoring and Risk Assessment of Marine Biotoxins on the Basis of Chemical and ... 
      Daneshian, Mardas; Botana, Luis M.; Dechraoui Bottein, Marie-Yasmine; Buckland, Gemma; Campàs, Mònica; Dennison, Ngaire; Dickey, Robert W.; Diogène, Jorge; Fessard, Valérie; Hartung, Thomas; Humpage, Andrew; Leist, Marcel; Molgó, Jordi; Quilliam, Michael A.; Rovida, Costanza; Suárez Isla, Benjamín; Tubaro, Aurelia; Wagner, Kristina; Zoller, Otmar; Dietrich, Daniel (Spektrum Akademischer Verlag-Springer-Verlag Gmbh, 2013)
      Aquatic food accounts for over 40% of global animal food products, and the potential contamination with toxins of algal origin - marine biotoxins - poses a health threat for consumers, The gold standards to assess toxins ...
