MTT Vs WST-1, efficiency, cost, time, and waste generation: evaluating the silver nanoparticles cytotoxicity by López, Israel, Balderas-Rentería, Isaías, Gómez, Idalia, González-Santiago, Omar, González-Barranco, Patricia, Garza-Ocañas, Lourdes, Ramírez-Cabrera, Mónica A

“…Por otro lado, el ensayo MTT requirió 2,5 h más y produjo más de tres veces el volumen de desechos que el ensayo WST-1.Abstract MTT and WST-1 are the cell viability assays frequently used without even considering a different choice; however, both methods require specific procedures and materials that are not common among them and thus implies a different theoretical basis, which are important aspects to denote when is necessary to choose an assay consciously. On the other hand, metallic nanoparticles, mostly synthesized by a chemical route, are studied in the health area as an alternative for therapeutic agents; however, they have proven to be toxic due to their capping environment and reaction by-products that are difficult to purify. …”

LA DIETA Y SU IMPORTANCIA EN LA CARIES DENTAL by Cisneros Estala, Martha Aidee, Tijerina González, Liliana Zandra, Cantú Martínez, Pedro César

“…The significance of these data contributes to the establishment of institutional policies specific oral health, to advocate more effectively on the health of individuals There is a positive correlation of the cariogenic potential of foods consumed and the DMFT, given the need for treatment in college students. Observational, cross-sectional descriptive and correlational study of 111 college seniors graduate, intraoral examination was performed to calculate the DMFT Index and Index of Treatment Needs by decay, to others a survey to measure risk cariogenic; to perform the statistical analysis we used Excel 2007 ®.One was that 66,67% of the population belonged to the femenine and  33,30% to the masculine, with an average of 22,09 ± 2.02 age; the 9,09% of the studied population are free of decay, the average of DMFT found in the study population was of 9,73 ± 5,16 , while only 79.1% of these pieces had no need for any treatment and 43% have a need for treatment good, only 10.8% of the population carry a low risk diet cariogenic. …”

Estimation of lower-limb joint torques from EEG signals of gait initiation movements using a machine learning scheme by Alvarado Ruiz, Lucero Esmeralda

“…However, there is still no feasible method to acquire and process these signals in a way that allows reliable estimations; moreover, there is lack of proposes for the estimation of kinetic variables of the lower limb, such as joint torques, during the execution of movements outside the gait cycle, such as gait initiation movements. Hence, this thesis presents a scheme for estimating lower-limb joint torques from EEG acquired during the execution of gait initiation movements. …”
