Inversión conjunta de sísmica de refracción y sondeos eléctricos verticales utilizando programación evolutiva. por Merlo Mejía, Jorge Luis

“…The main objective of the present work is to introduce an algorithm capable of solving the joint inversion of both methods using the Evolutionary Programming technique, a variant of Monte Carlo methods inspired by the evolution of the species and the natural selection from which it was obtained an estimation of parameters quite close to those proposed in direct modeling, it was proved that it is capable of being used in synthetic data contaminated with noise, validating its effectiveness in order to be able to work with real data.…”

Efecto bactericida de nanopartículas de plata sobre microorganimos resistentes a los antibióticos in vitro por Jerez Urriolagoitia, Mónica Marcela

“…The results showed a bactercidal effect of silver nanoparticles against the four bacteria proved, this effect was independent of resistance features to antibiotics, the minimum bactericidal concentration was 25 µg/ml and 12.5 µg/ml for Gram positives and Gram negatives bacteria respectively, the antibacterial effect was dependent as the concentration of nanoparticles as number of UFC used, how was expected for fewer bacterial concentrations, fewer concentrations of silver nanoparticles were used in order to get a bactericidal effect. …”

Homogeneidad genética en mujeres con cáncer de mama en el noreste de México por Calderón Garcidueñas, Ana Laura

“…Although there are studies in the Northeast Mexico that had proved genetic homogeneity in aleatory population using blood groups, DNAmt and polymorphic markers such as D1S80 and HLA-DQA1, it is very important to establish if there is genetic homogeneity not only in general population, but also in cancer population. …”

Efecto del silenciamiento de E6 y E7 (HPV 16) sobre la expresión de MDM2 en una línea celular de cáncer cervical por Díaz García, Daniel

“…The carcinogenic potential of HPV infections is mainly due to the integration of the viral DNA into the genomic material of the host cell and the subsequent constitutive expression of the E6 and E7 genes, which have the ability of repressing tumor suppressing proteins such as P53 and Rb. It has been proved that the continuous expression of these oncoproteins is essential for the conservation of the malignant state of the transformed cells and that the repression of either, can and will induce growth arrest or apoptosis or both. …”

Ecología y fisiología en las primeras fases de crecimiento de plantas suculentas en el sur del desierto chihuahuense en México y las montañas de Córdoba en Argentina. por Pérez Sánchez, Reyes Manuel

“…Specifically, in this study we measured the variables related to chlorophyll fluorescence: Effective quantum yield of photosystem II (ΦPSII) and electron transport rate (ETR), as well as relative growth rate (RGR) and its components (net assimilation rate, NAR, and proportion of leaf or photosynthetic area, LAR), root to shoot ratio (R/S) and relative water content (RWC), for seedlings transplanted under nurse plants and seedlings transplanted under direct sunlight. It was proved that ΦPSII, LAR, R/S ratio and RWC were low, and ETR, RGR and NAR were higher for seedlings of seven succulent species common to the Southern Chihuahuan Desert (Agave lechuguilla, A. salmiana, Echinocactus platyacanthus, Ferocactus histrix, Myrtillocactus geometrizans, Stenocactus coptonogonus y Yucca filifera) grown under direct sunlight, in comparison with seedlings transplanted under nurse mezquite trees. …”
