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

“…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. …”

Design for Six Sigma: Approach for reliability and low-cost manufacturing (Diseño para Seis Sigma: Enfoque para la fiabilidad y fabricación de bajo costo) por Cruz Álvarez, Jesús Gerardo

“…The aim of this study is to discuss new product development based on a traditional stage-gate process and to examine how new product development [NPD] tools, such as lean design for Six Sigma, can accelerate the achievement of the main goals of NPD: reliable product quality, cost-effective implementation, and desired time-to-market. These new tools must be incorporated into a new approach to NPD based on the Advanced Product and Quality Planning methodology. …”

Potential Mechanism of Action of 3′-Demethoxy-6-O-demethyl-isoguaiacin on Methicillin Resistant Staphylococcus aureus por Favela Hernández, Juan Manuel de Jesús, Clemente Soto, Aldo Francisco, Balderas Rentería, Isaías, Garza González, Elvira, Camacho Corona, María del Rayo

“…Results of microarray genome expression were validated by real-time polymerase chain reaction (RT-PCR). The genetic profile expression results showed that lignan 3′-demethoxy6-O-demethylisoguaiacin had activity on cell membrane affecting proteins of the ATP-binding cassette (ABC) transport system causing bacteria death. …”

Potential mechanism of action of meso-dihydroguaiaretic acid on mycobacterium tuberculosis H37Rv por Clemente Soto, Aldo Francisco, Balderas Rentería, Isaías, Rivera, Gildardo, Segura Cabrera, Aldo, Garza González, Elvira, Camacho Corona, María del Rayo

“…Therefore, in this study we carry out the gene expression from total RNA obtained from M. tuberculosis H37Rv treated with MDGA using microarray technology, which was validated by quantitative real time polymerase chain reaction. Results showed that the alpha subunit of coenzyme A transferase of M. tuberculosis H37Rv is present in both geraniol and 1-and 2-methylnaphthalene degradation pathways, which are targeted by MDGA. …”

Differences in stress and happiness between owners who perceive their dogs as well behaved or poorly behaved when they are left alone por González Ramírez, Mónica Teresa, Vanegas Farfano, Minerva, Landero Hernández, René

“…It is possible that humans with higher levels of stress do not have a relaxed relationship with their dogs, which may contribute to their annoyance about their dogs’ behavior, and they spend less time with them. This could explain why they perceived their dogs as having separation-related behavioral problems. …”
