    Microbiota gastrointestinal y síndrome de intestino irritable por García Mazcorro, José Francisco, Cruz Valdez, Julio César, Marroquín Cardona, Alicia Guadalupe, Sánchez Casas, Rosa María

    Publicado 2014
    “…And finally, we agree that our already extensive review fell short of analyzing the use of probiotics, prebiotics, and even synbiotics, in the treatment of IBS, but we felt these topics should be the subject of another review. As a matter of fact, a very recent systematic review of the literature has reported that probiotics were superior to placebo due to a lower frequency of IBS symptom persistence (55.8% vs. 73.1%).4 In addition, probiotics were shown to be superior to placebo in the improvement of overall symptoms, abdominal pain, subjective abdominal bloating, and flatulence. …”

    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

    Publicado 2013
    “…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. …”
