      Activation of T lymphocytes by human pathogens is a key step in the development of immune-mediated neurologic diseases. Because of their ability to invade the CNS and their increased secretion of proinflammatory cytokines, ...

      T regulatory (Treg) cells have a major role in the maintenance of immune tolerance against self and foreign antigens through the control of harmful inflammation. Treg cells exert immunosuppressive function by several ...

      En este manuscrito se analiza y evalúa el establecimiento y operación de un Teahouse de estilo contemporáneo en Santiago de Chile emulando el modelo de negocios de la cadena de Teahouse Australiana "T2" (www.t2tea.com). El ...
    • Fones, Elizabeth; Amigo, Hannelore; Gallegos, Kimie; Guerrero, Anibal; Ferreira, Jorge (1989)
      The effect of t-butyl-4-hydroxyanisole (BHA), a widely used food antioxidant additive, on the culture growth, oxygen consumption, and redox state of some electron carriers of intact TA3 and 786A ascites tumor cells has ...
    • Aldunate, Jorge; Ferreira, Jorge; Letelier Muñoz, María Eugenia; Repetto Scaramelli, Yolanda; Morello Casté, Antonio (1986)
      t-Butyl-4-hydroxyanisole, an antioxidant food additive, inhibited the growth of Trypanosoma cruzi by almost 100% at 0.5 mM concentration. This compound inhibited 70% of oxygen consumption of epimastigotes. The redox level ...
    • Ibberson, Mark R.; Copier, John P.; Llop Romero, Elena; Navarrete, Cristina; Hill, Adrian V.S.; Cruickshank, J. Kennedy; So, Alex K.L. (1998)
      Interactions involving the T-cell receptor (TCR) and major histocompatibility complex (MHC) are fundamental to the generation of a specific immune response. The study of interpopulation differences in TCR genes may identify ...
    • Aravena, Mauricio; Pérez, C.; Pérez, V.; Acuña Castillo, Claudio; Gómez, Christian; Leiva Salcedo, Elías; Nishimura, Sumiyo; Sabaj, B.; Walter, Robin Ann (ELSEVIER SCI IRELAND LTD, 2005-03)
      T-kininogen (T-KG) is a precursor of T-kinin, the most abundant kinin in rat serum, and also acts as a strong and specific cysteine proteinase inhibitor. Its expression is strongly induced during aging in rats, and expression ...
    • Pérez, Viviana; Leiva Salcedo, Elías; Acuña Castillo, Claudio; Aravena, Mauricio; Gómez, Christian; Sabaj Diez, Valeria; Colombo, Alicia; Nishimura, Sumiyo; Pérez Núñez, Claudio; Walter, Robin Ann; Sierra, Felipe (ELSEVIER, 2006-03)
      Basal proliferation of endothelial cells increases with age, and this might play a role in the etiology of age-related vascular diseases, as well as angiogenesis. Serum kininogen levels increase during aging in rats and ...
    • Leiva-Salcedo, Elias; Perez, Viviana; Acuña Castillo, Claudio; Walter, Robin Ann; Sierra, Felipe (Society of Biology of Chile, 2002)
      Serum levels of T-kininogen increase dramatically as rats approach the end of their lifespan. Stable expression of the protein in Balb/c 3T3 fibroblasts leads to a dramatic inhibition of cell proliferation, as well as ...
    • Acuña Castillo, Claudio; Aravena, Mauricio; Leiva Salcedo, Elías; Pérez, Viviana; Gómez, Christian; Sabaj Diez, Valeria; Nishimura, Sumiyo; Pérez Núñez, Claudio; Colombo, Alicia; Walter, Robin Ann; Sierra, Felipe (ELSEVIER, 2005-12)
      Plasma levels of kininogens increase with age in both rats and humans. Kininogens are inhibitors of cysteine proteinases, and filarial cysteine proteinase inhibitors (cystatins) reduce the proliferation of T cells. We ...

    • Bruhn, Henning; Stein, Maya (SIAM PUBLICATIONS, 2010)
      A connected graph G is called t-perfect if its stable set polytope is determined by the non-negativity, edge and odd-cycle inequalities. More- over, G is called strongly t-perfect if this system is totally dual inte- gral. ...
