Análisis del daño al DNA de monocitos humanos infectados con Mycobacterium tuberculosis mediante la técnica de DBD-FISH.
Published 2017“…During infection, alveolar macrophages are the first cells to deal with the bacteria, but M. tuberculosis has the ability to invade and replicate itself inside other non-professionals phagocytic cells. Once the bacilli enters the macrophage, it triggers processes that may lead to cellular death, either by necrosis or apoptosis. …”

Análisis geomecánico utilizando el método RMR, de un macizo rocoso ubicado en el km 40 de la carretera Linares – Iturbide.
Published 2017“…The RMR (ROCK MASS RATING) method proposed by Bieniawski in the 80's will be used as a parameter to classify the quality of the rock mass from a geological engineer point of view, so with complementary data to establish the parameters of the rocky mass for the purpose of slope stability, determining the degree of risk and generating necessary measures to deal with possible damages that could be generated. Once the results are obtained, they will be checked to see if the stability of a rock mass is directly related to the distribution and orientation of the discontinuities, as well as its dimensions and arches, among other factors, and to see the causes of the discontinuities, which the slope is metastable.…”
