    • Acute Copper and Ascorbic Acid Supplementation Inhibits Non-heme Iron Absorption in Humans 
      Olivares Grohnert, Manuel; Figueroa Donoso, Constanza; Pizarro Aguirre, Fernando (Humana Press, 2016)
      The objective of the study is to determine the effect of copper (Cu) plus the reducing agent ascorbic acid (AA) on the absorption of non-heme iron (Fe). Experimental study with block design in which each subject was his ...
    • Effect of various calcium salts on non-heme iron bioavailability in fasted women of childbearing age 
      Candia, Valeria; Ríos Castillo, Israel; Carrera Gil, Frank; Vizcarra, Berta; Olivares, Manuel; Chaniotakis, Sotiris; Pizarro Aguirre, Fernando (Elsevier, 2018)
      Introduction: Micronutrient deficiencies are one of the most important public health issues worldwide and iron (Fe) deficiency anemia is the most prevalent micronutrient deficiency. Iron deficiency often coexists with ...
    • Effects of acute dietary iron overload in pigs (sus scrofa) with induced type 2 diabetes mellitus 
      Espinoza, A.; Morales, S.; Arredondo Olguín, Miguel (Springer, 2014)
      Epidemiological studies have reported an association between high iron (Fe) levels and elevated risk of developing type 2 diabetes mellitus (T2D). It is believed that the formation of Fe-catalyzed hydroxyl radicals may ...
    • Effects of High Iron and Glucose Concentrations over the Relative Expression of Bcl2, Bax, and Mfn2 in MIN6 Cells 
      Fuentes, Marcela; Andrews, Mónica; Arredondo Olguín, Miguel Armando (Springer Science+Business Media, 2013)
      Type 2 diabetes is characterized by hyperglycemia and oxidative stress. Hyperglycemia is linked to mitochondrial dysfunction and reduced β-cell mass due to the reduced expression of genes such as Mfn2 as well as ...
    • Exploratory study: excessive iron supplementation reduces zinc content in pork without affecting iron and copper 
      Middleton Santibáñez, Maureen; Olivares Grohnert, Manuel Alonso; Espinoza, Alejandra; Arredondo Olguín, Miguel Armando; Pizarro Aguirre, Fernando Dagoberto; Valenzuela Venegas, Carolina Paz (MDPI, 2021)
      Currently, all pigs raised on intensive farms develop iron-deficiency anemia if they do not receive supplemental iron at birth. Weaning diets commonly contain high concentrations of iron, and the effect on the copper and ...
    • 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 ...
    • High Levels of Iron Status and Oxidative Stress in Patients with Metabolic Syndrome 
      Leiva, Elba; Mujica, Verónica; Sepúlveda, Pablo; Guzmán, Luis; Núñez, Sergio; Orrego, Roxana; Palomo, Iván; Andrews, Mónica; Arredondo Olguín, Miguel Armando (Springer, 2013)
      Studies concerning oxidative stress (OxE) parameters have increased, mainly because of its important role in cardiovascular diseases and diabetes complications. The main objective of this study was to evaluate iron ...
    • One-month of calcium supplementation does not affect iron bioavailability: A randomized controlled trial 
      Ríos Castillo, Israel; Olivares Grohnert, Manuel; Brito, Álex; López de Romaña, Daniel; Pizarro Aguirre, Fernando (Elsevier, 2014)
      Objectives: Calcium (Ca) and iron (Fe) are essential minerals for normal growth and development. Although previous studies have shown that Ca inhibits acute Fe absorption, there is no evidence of the possible long- or ...
    • Prevalence of Anemia in Latin America and the Caribbean 
      Mujica Coopman, María; Brito, Alex; López de Romaña, Daniel; Ríos Castillo, Israel; Cori, Héctor; Olivares, Manuel (SAGE, 2015)
      Background: In Latin America and the Caribbean, anemia has been a public health problem that affects mainly women of childbearing age and children under 6 years of age. However, the current prevalence of anemia in this ...
