CD20 expression in B-cell precursor acute lymphoblastic leukemia is common in Mexican patients and lacks a prognostic value por Solano Genesta, Manuel, Tarín Arzaga, Luz, Velasco Ruiz, Ileana, Lutz Presno, Julia A., González Llano, Óscar, Mancías Guerra, Consuelo, Rodríguez Romo, Laura, Ruiz Delgado, Guillermo J., Ruiz Argüelles, Guillermo José, Jaime Pérez, José Carlos, Gómez Almaguer, David

“…There was no correlation between CD20 expression and age, white blood cell count, or cytogenetic abnormalities. Despite the fact that CD20-positive ALL patients had a tendency toward a worse outcome, there was no significant difference between patients with and without CD20 expression in 3-year overall survival 65 vs. 82% (P = 0.14), and cumulative incidence of relapse 36 vs. 18% (P = 0.3) in pediatric patients and 51 vs. 53% (P = 0.31) and 35 vs. 38% (P = 0.6) in adults, respectively. …”

Spatial technologies to evaluate vectorial samples quality in maps production por Cárdenas Tristán, Abraham, Treviño Garza, Eduardo Javier, Aguirre Calderón, Oscar Alberto, Jiménez Pérez, Javier, González Tagle, Marco Aurelio, Némiga, Xanat Antonio

“…Despite significant progress in recent years, the methodological conceptualization for assessing quality of vectors that integrate digital mapping is still a complicated task. Due to the fact that there is not an official scheme in Mexico to evaluate vectorial cartographic quality, an alternative methodology is proposed for assessing vectorial quality through analysis of samples at various vectorial scales from the Mexican Republic coverage. …”

Gender bias in education opportunities for population aged 12-18 in Mexico: 1992-2004 por Aguayo Téllez, Ernesto, Chapa Cantú, Joana Cecilia, Rangel González, Erick, Treviño Villarreal, María de Lourdes, Valero Gil, Jorge Noel

“…Using an OLS-Robust model and a ML-Random Effects model for the years 1992, 1998 and 2004 of ENIGH, we did not find enough statistical evidence to support the idea that poor families, nether in rural nor in urban areas, provide more education to their 12 to 18 years old sons or daughters. In fact, contrary to the common belief, we found that non-poor families, invest more in the education of their daughters, especially in the urban areas. …”
