  1. Comparative role of betalains and other key antioxidant metabolites in the photoprotection against acute exposure to UV-B radiation in Chenopodium quinoa and C. berlandieri seedlin... por Causin, Humberto F., Cá, Federico D., Spotorno, Viviana Graciela, Palacios, María B., Martínez Tosar, Leandro, Burrieza, Hernán F., Tossi, Vanesa E.

    Publicado 2025
    “…In the present work we aimed to determine whether UV-B radiation induces the production of betalains, and evaluated the role of these pigments and other key antioxidants in preventing oxidative damage, in seedlings of C. quinoa (ecotypes CICA and Villarrica) and its close relative C. berlandieri Moq., grown in darkness and after exposure to an acute pulse of UV-B radiation (24 h, 2.5 W m−2). UV-B significantly increased MDA accumulation and induced the production of betalains (particularly betacyanins), polyphenols and UV-B-absorbing compounds in all seedlings tested. …”

  2. Influence of agricultural practices on nitrogen-cycling microbial communities and their interaction with mycorrhizae in Argentine Puna soils por Hernandez Guijarro, Keren, Covacevich, Fernanda, Caruso, Graciela, Castro, Dario Carlos, Feingold, Sergio Enrique

    Publicado 2025
    “…This study aimed to investigate the impact of agricultural practices on N-cycling microorganisms and arbuscular mycorrhizal fungi (AMF) interactions in Abra Pampa soils, located 3487 m above sea level. We conducted three annual samplings during the summers of 2020, 2021, and 2022 across four treatments: two agricultural plots (A1 and A2) amended with llama manure, each under different crop rotations - A1: Andean potato-quinoa-mallow and A2: quinoa-triticale-mallow; one soil under decomposing llama manure (BG) adjacent to agricultural plots; and a pristine control soil covered with native vegetation. …”

  4. Changes in the aerobic vaginal flora after treatment with different intravaginal devices in ewes por Manes, Jorgelina, Fiorentino, María Andrea, Kaiser, German Gustavo, Hozbor, Federico Andres, Alberio, Ricardo, Sánchez, Esteban O., Paolicchi, Fernando

    Publicado 2019
    “…At device withdrawal, each ewe was treated with 200 IU eCG i.m. Standard bacteriological procedures were performed on vaginal mucus samples obtained before the introduction of the devices, at device withdrawal and on the day of AI in all groups. …”
