    • Association of anions to cationic micelles 
      Bartet, Daniel; Gamboa, Consuelo; Sepúlveda, Luis (1980)
      The relative association degrees of different anions to micelles of hexadecyltrimethylammonium bromide (CTA) were measured by spectrophotometrically determining the amounts of p-toluenesulfonate (TOS) or benzenesulfonate ...

      Díaz-Toro, Felipe; Nazzal Nazal, Carolina; Verdejo, Hugo; Rossel, Víctor; Castro, Pablo; Larrea, Ricardo; Concepción, Roberto; Sepúlveda, Luis; Sepúlveda, Luis (Sociedad Medica de Santiago, 2017)
      © 2017 Rev Med Chile. All right reserved. Background: Frailty is a geriatric syndrome characterized by a progressive impairment in the subjects’ ability to respond to environmental stress. Frailty is more commonly found ...
    • Free energies of transfer of anions from water to cationic micelles from ionic exchange measurements 
      Gamboa, Consuelo; Sepúlveda, Luis; Soto, Ramón (1981)
      Ionic exchanges for several anions in hexadecyltrimethylammonium (CTA) have been measured by ultrafiltration and by the shift in the concentration of ferric thiocyanate complex by CTA addition. The results are compared ...
    • Galectina-3: experiencia en pacientes chilenos con diagnóstico de insuficiencia cardíaca descompensada 
      Rossel Mariángel, Víctor; Díaz Toro, Felipe; Verdejo, Hugo; Concepción, Roberto; Sepúlveda, Luis; Castro, Pablo; Vukasovic, José Luis; Bernales, Angie; Bernales, Angie (Sociedad Medica de Santiago, 2017)
      Background: Galectin-3 (Gal-3) is a mediator of myocardial fibrosis involved in cardiac remodeling and a potential new prognosis marker in heart failure (HF). Aim: To measure Gal-3 at the moment of discharge in patients ...
    • High viscosities of cationic and anionic micellar solutions in the presence of added salts 
      Gamboa, Consuelo; Sepúlveda, Luis (1986)
      Viscosities of micelles of cetyltrimethylammonium salts (CTAX, X = tosylate (TOS-), Cl-, Br-, NO3 -) in the presence of Cl-, Br-, NO3 -, benzene sulfonate (BS-), and TOS-, of cetylpyridinium chloride (CpyC) in the presence ...

      Sepúlveda, Luis; Cortés, Juan (1985)
      Ionization degrees (α) of micelles of hexadecyltrimethylammonium (CTAX) and tetradecyltrimethylammonium (TTAX) (X = OH-, Br-, Cl-, NO3 -, SO4 2-, and CO3 2-) were measured by a modified free electrophoresis method and by ...
