El envejecimiento modifica la expresión de genes de respuesta antioxidante en Yarrowia lipolytica. by Miranda Roblero, Hipólito Otoniel

“…Las ERO están controlados finamente por las enzimas antioxidantes: catalasas (Cat), superóxido dismutasas (Sod) y glutatión peroxidasas (Gpx); sin embargo, cuando se rompe el equilibrio redox entre las enzimas antioxidantes y los niveles de las ERO, las ERO reaccionan con macromoléculas (hidratos de carbono, lípidos, proteínas y ácidos nucleicos) oxidándolas y ocasionando daño celular a mayor escala que converge en estrés oxidativo (EO). …”

Zirconia doped with La Fe synthesized by sol gel, used in the trichloroethylene catalytic combustion by Rivera de la Rosa, Javier, Hernández, Araceli, Ledezma Sánchez, Juan José, Rojas, Fernando, Goller, Gülteking

“…The sol-gel method has attracted considerable attention for the preparation of metallic catalysts, since the constituents are mixed in an atomic scale and this generates a uniform distribution of active metals upon the support [4]. …”

Bacterial Exopolysaccharides as Reducing and/or Stabilizing Agents during Synthesis of Metal Nanoparticles with Biomedical Applications by Escárcega González, Carlos Enrique, Garza Cervantes, Javier Alberto, Vázquez Rodríguez, Augusto, Morones Ramírez, José Rubén

“…Recently, synthesis and stabilization of metal nanoparticles have been of interest because their usefulness for many biomedical applications, such as antimicrobials, anticancer drugs, antioxidants, drug delivery systems, chemical sensors, contrast agents, and as catalysts. In this context, bacterial EPSs have been explored as agents to aid in a greener production of a myriad of metal nanoparticles, since they have the ability to reduce metal ions to form nanoparticles and stabilize them acting as capping agents. …”

Rapid NO conversion with an enhanced Sm+3-TiO2 photocatalyst by Alviz Meza, A., Sierra González, X., Martínez de la Cruz, A., Colina Marquez, J.A.

“…The acidic pH favored the presence of the anatase crystalline phase, the most photoactive and interesting for photocatalytic applications. Furthermore, these catalysts were evaluated in a lab-scale UV photoreactor following the NO conversion via chemiluminescence, according to the ISO standard 22197–1. …”

Metal Complexes Containing Natural and Artificial Radioactive Elements and Their Applications by Kharissova, Oxana Vasilievna, Méndez Rojas, Miguel Ángel, Kharisov, Boris I., Méndez, Ubaldo, Martínez, Perla

“…On the basis of their properties, several mono-, bi-, tri-, tetra- or polydentate ligands have been designed for specific recognition of some particular radionuclides, and can be used in the processes of nuclear waste remediation, i.e., recycling of nuclear fuel and the separation of actinides and fission products from waste solutions or for analytical determination of actinides in solutions; actinide metal complexes are also usefulas catalysts forcoupling gaseous carbon monoxide,as well as antimicrobial and anti-fungi agents due to their biological activity. …”
