    Evaluation of hemoglobin performance in the assessment of iron stores in feto-maternal pairs in a high-risk population: receiver operating characteristic curve analysis by Jaime Pérez, José Carlos, García Arellano, Gisela, Méndez Ramírez, Nereida, González Llano, Óscar, Gómez Almaguer, David

    Published 2015
    “…Receiver operating characteristic curve analysis was applied to select the cut-off points that better reflected iron stores. Results: The Hb cut-off point selected by receiver operating characteristic curve analysis in women was <11.5 g/dL (sensitivity: 60.82, specificity: 53.33%, Youden Index: 0.450). …”

    Análisis de expresión de genes de Mycobacterium tuberculosis durante la infección a macrófagos by Barrios García, Hugo Brígido

    Published 2006
    “…THP-1 cells monolayers differentiated to macrophages by phorbol myristate acetate (PMA) were infected with M. tuberculosis strains CDC1551, H37Rv and DR689 with a variable multiplicity of infection (MOI): 10:1, 1:1 and 0.1:1 (bacteria:macrophage) and incubated at various time points. Cytotoxicity was observed as areas of clearing and cell agglomeration and the effect was dependent on bacilli inoculum and incubation time. …”

    Electrochemical Noise Analysis of Nickel Based Superalloys in Acid Solutions by Gaona Tiburcio, Citlalli, Aguilar M, M.R, Zambrano Robledo, Patricia del Carmen, Estupiñan López, Francisco Humberto, Cabral Miramontes, José Ángel, Nieves Mendoza, Demetrio, Castillo González, E., Almeraya Calderón, Facundo

    Published 2013
    “…In this paper we study the corrosion behavior of nickel-based superalloys (Inconel 690, Inconel 718, Incoloy 800, Incoloy 825), compared with commercial steels (carbon Steel 1018 and stainless steel 304), in acid (10% H2SO4 and 10 % CH3COOH) and H2O at room temperature, by electrochemical noise technique, with sampling 1024 points per second. Statistical analysis of electrochemical noise technique yielded LI localization index, the type of corrosion and the noise resistance as well as the corrosion rate. …”
