Effect of the Microstructures Formed in Cements Modified by Limestone Agave Bagasse Ash, Fly Ash, Geothermal Nano-SiO2 Waste and Silica Fume on Chloride Ion Penetration Resistance por Puente Ornelas, Rodrigo, Chávez Guerrero, Leonardo, Fajardo San Miguel, Gerardo, Rodríguez, E. A., Trujillo Álvarez, Alejandro, Rivas Lozano, Hugo E., Delgadillo Guerra, Herlinda María

“…It is also worth mentioning that a the pastes experienced a higher densification value, mainly due to the addition of GNW, which promotes the development of a matrix with reduced porosity when compared with values measured at 100% OPC. The chlorine ion penetration ratio had also low values giving an ion penetration resistance around 57 % less. …”

Evaluación in vitro, ex – vivo e in silico de nuevos derivados de 1,4-naftoquinonas sobre epimastigote y tripomastigote de Trypanosoma cruzi por Becerra Ramos, Nohemi Alejandra

“…The evaluation of cytotoxicity was carried out in 2 cell lines, in both it was observed that there is no cytotoxicity at different concentrations, in the compound Ce-Q8 in line of hepatocytes in the 3 concentrations shared a toxicity not greater than 25% and as a complement was decided make in silico trials using the pharmacophoric model, where the two halogenated groups (Bromine and chlorine) favored their activity, possibly benefiting the lipophilicity of the compound. …”

Inactivación de norovirus mediante compuestos naturales. por Sotolongo Rodríguez, Dianelys

“…At present, no effective treatment has been developed against this disease since sanitization based on chlorine solutions used in the food industry, as well as handwashing with soap and water, have been inefficient in achieving the total removal of the pathogen.; in addition there are no efficient vaccines due to their great genetic variability and the lack of a robust study model. …”
