    Artificially disordered birefringent optical fibers por Herath, S., Puente, N. P., Chaikina, E. I., Yamilov, A.

    Publicado 2012
    “…Complete mode mixing in a segment of fiber as short as ∼ 10cm after 3.6dB insertion loss is experimentally observed. Equal excitation of all modes in such a multi-mode fiber creates the conditions to maximize the information capacity of the system under e.g. multiple-input-multiple-output (MIMO) transmission setup.…”

    Effect of Glycine on Lead Mobilization, Lead-Induced Oxidative Stress, and Hepatic Toxicity in Rats por Alcaraz Contreras, Yolanda, Garza Ocañas, Lourdes, Carcaño Díaz, Katya, Ramírez Gómez, Xóchitl Sofía

    Publicado 2011
    “…The effect of these treatments on parameters indicative of oxidative stress (glutathione and malondialdehyde levels), the activity of blood δ-aminolevulinic acid dehydratase, and lead concentration in blood, liver, kidney, brain, and bone were investigated. Liver samples were observed for histopathological changes. Glycine was found to be effective in (1) increasing glutathione levels; (2) reducing malondialdehyde levels; (3) decreasing lead levels in bone with the highest dose. …”
