Necesidad de tratamiento ortodóntico y prevalencia de caries en comunidad indígena de Chiapas y estudiantes de Monterrey. by Palafox Ibarra, Edgar Alejandro

“…We believe that, in the case of the need for orthodontic treatment, the prevalence in Monterrey is greater due to various factors such as the amount of pollutants in the air, more people with allergic problems and the type of mestizo race present in the area. Regarding the caries index, the caries index in Chiapas was higher, this seems to be due to the lack of knowledge about oral hygiene, its consequences, and the little importance given to it in the Chiapas area; as well as the type of diet to which they are subjected, which is high in carbohydrates.…”

Silver Nanoparticles Synthesized through Green Methods Using Escherichia coli Top 10 (Ec-Ts) Growth Culture Medium Exhibit Antimicrobial Properties against Nongrowing Bacterial Str... by Baltazar Encarnación, Esther, Escárcega González, Carlos Enrique, Vasto Anzaldo, Ximena G., Cantú Cárdenas, María Elena, Morones Ramírez, José Rubén

“…Here, after characterization of the different silver nanoparticles produced with the different media, we demonstrated that the LB culture-conditioned media was the most suitable to produce them since they displayed the most narrow size distribution, with an average 10.6 nm in diameter, a relatively low standard deviation of 5.5 nm, and a narrow UV-vis spectrum absorption peak at 420 nm. The other methods presented larger nanoparticle sizes and broader size distributions. …”
