    • Batch reactor performance for the enzymatic synthesis of cephalexin: influence of catalyst enzyme loading and particle size 

      Valencia, Pedro; Flores, Sebastián; Wilson, Lorena; Illanes, Andrés (Elsevier, 2012-01)
      A mathematical model is presented for the kinetically controlled synthesis of cephalexin that describes the heterogeneous reaction–diffusion process involved in a batch reactor with glyoxyl-agarose immobilized penicillin ...
    • Calcium does not inhibit the absorption of 5 milligrams of nonheme or heme iron at doses less than 800 milligrams in nonpregnant women 

      Gaitán, Diego; Flores, Sebastián; Saavedra, Pía; Miranda, Constanza; Olivares, Manuel; Arredondo, Miguel; López de Romaña, Daniel; Lönnerdal, Bo; Pizarro Aguirre, Fernando (2011)
      Calcium is the only known component in the diet that may affect absorption of both nonheme and heme iron. However, the evidence for a calcium effect on iron absorption mainly comes from studies that did not isolate the ...
    • The Effect of Plant Proteins Derived from Cereals and Legumes on Heme Iron Absorption 

      Weinborn, Valerie; Pizarro Aguirre, Fernando; Olivares Grohnert, Manuel; Brito, Alex; Arredondo Olguín, Miguel; Flores, Sebastián; Valenzuela Venegas, Carolina (MDPI AG, 2015)
      The aim of this study is to determine the effect of proteins from cereals and legumes on heme iron (Fe) absorption. The absorption of heme Fe without its native globin was measured. Thirty adult females participated in two ...
    • The effect of proteins from animal source foods on heme iron bioavailability in humans 

      Pizarro Aguirre, Fernando; Olivares Grohnert, Manuel; Valenzuela Venegas, Carolina; Brito, Alex; Weinborn, Valerie; Flores, Sebastián; Arredondo Olguín, Miguel (Elsevier, 2016)
      Forty-five women (35-45 year) were randomly assigned to three iron (Fe) absorption sub-studies, which measured the effects of dietary animal proteins on the absorption of heme Fe. Study 1 was focused on heme, red blood ...
    • Heme oxygenase 1 overexpression increases iron fluxes in Caco-2 cells 

      Mendiburo, María José; Flores, Sebastián; Pizarro Aguirre, Fernando; Arredondo Olguín, Miguel Armando (2006)
      Heme oxygenase-1 is a microsomal enzyme that, when induced by stress, protects the cells from oxidative injury. Heme oxygenase-1 participates in the cleavage of the heme ring producing biliverdin, CO and ferrous Fe. The ...
    • Metodología de Cálculo de Valores de Inversión para Sistemas de Subtransmisión 

      Campos Flores, Sebastián Enrique (Universidad de ChileCyberDocs, 2011)
      De acuerdo a la legislación vigente en Chile cada cuatro años se deben realizar estudios para determinar el valor anual de los sistemas de subtransmisión (VASTx), a modo de mantener una tarificación adecuada para el sistema ...
    • Mouse divalent metal transporter 1 is a copper transporter in HEK293 cells 

      Arredondo Olguín, Miguel; Mendiburo Seguel, María José; Flores, Sebastián; Singleton, Steven T.; Garrick, Michael D. (Springer Science+Business Media, 2014)
      Divalent Metal Transporter 1 (DMT1) is an apical Fe transporter in the duodenum and is involved in endosomal Fe export. Four protein isoforms have been described for DMT1, two from mRNA with an iron responsive element ...
    • Pectin esterification degree in the bioavailability of non heme iron in women 

      Jaramillo, Angela; Molina Carrasco, Paulina; Briones, Lautaro; Flores, Sebastián; Olivares, Manuel; Pizarro Aguirre, Fernando (Springer, 2018)
      Pectins are a type of soluble fiber present in natural and processed foods. Evidence regarding the effect of esterification degree of pectins on iron absorption in humans is scarce. In the present study, the effect of ...
    • Pectin Esterification Degree in the Bioavailability of Non-heme Iron in Women 

      Jaramillo, Angela; Molina, Paulina; Briones, Lautaro; Flores, Sebastián; Olivares, Manuel; Pizarro, Fernando (Humana Press Inc., 2018)
      © 2017, Springer Science+Business Media New York. Pectins are a type of soluble fiber present in natural and processed foods. Evidence regarding the effect of esterification degree of pectins on iron absorption in humans ...
