      The relationship between asymptomatic shedding of bacterial enteropathogens and the hygiene habits of families who have had a child with typhoid fever (TF) are investigated. The sample was made up of 80 families: 40 families ...
    • Alvarez Alvarez, Miguel Adrián; Espinoza,; Figueroa Figueroa, Mónica; Diaz, Eloisa; Wurgaft, (1991)
      We studied the relation of habits related to the fecal-oral cycle and incidence of typhoid fever in children attending the school system for 1 to 2 years and in their families. The goal was to identify a predictor to detect ...

    • Casassus Montero, Simón; Storey, P. J.; Barlow, M. J.; Roche, P. F. (WILEY-BLACKWELL, 2005-06-01)
      The core of planetary nebula NGC 6302 is filled with high-excitation photoionized gas at low expansion velocities. It represents a unique astrophysical situation in which to search for hyperfine structure (HFS) in coronal ...
    • Chedraui, Peter; Pérez López, Faustino R.; Blumel, Juan E.; Hidalgo, Luis; Barriga, José (2009)
      Background. Postmenopausal metabolic changes increase cardiovascular risk and impair quality of life (QoL). Despite this, few reports have addressed the association of these changes with female sexuality. Objective. To ...
    • Bustamante Franco, Sebastián Felipe (Universidad de Chile, 2018)
      The main focus of this thesis is the study of monochromatic cycle partitions in uniform hypergraphs. The first part deals with Berge-cycles. Extending a result of Rado to hypergraphs, we prove that for all $r,k \in \N$ ...
    • Hirsch Birn, Sandra; Maza Cave, María Pía de la; Petermann, Margarita M.; Barrera, Gladys; Gattas, Vivien; Escobar, Edgardo; Yañez, Paulina; Glasinovic, Andrea; Bunout Barnett, Daniel (2002)
      Background: The relationship between hyperhomocysteinemia and cardiovascular disease has not been totally elucidated. Hypothesis: The study aimed to verify the association between hyperhomocysteinemia and endothelial ...
    • Hirsch Birn, Sandra; Ronco Macchiavello, Ana María; Vásquez, Marcela; Maza Cave, María Pía de la; Garrido, Argelia; Barrera, Gladys; Gattas, Vivien; Glasinovic, Andrea; Leiva, Laura; Bunout Barnett, Daniel (2004)
      The mechanism by which homocysteine (Hcy) causes endothelial dysfunction is probably mediated by oxidative stress. The aim of this study was to evaluate the effect of oxidative stress on endothelial function in young and ...
    • Rojas, Cecilia V.; Neely, Alan; Velasco-Loyden, Gabriela; Palma, Veronica; Kukuljan Padilla, Manuel (1999)
      Mutations in the human skeletal muscle Na+ channel underlie the autosomal dominant disease hyperkalemic periodic paralysis (HPP). Muscle fibers from affected individuals exhibit sustained Na+ currents thought to depolarize ...
    • Bravo Silva, Jaime (Centro de Estudios Académicos en Neuropsicología, 2016)
      There is an urgent need to increase the Joint Hypermobility Syndrome (JHS) awareness, that for most authors is the same as the Ehlers-Danlos Hypermobility type (formerly called EDS type III) that is a congenital, very ...
    • Pan, Li; Pezzuti, Todd; Lu, Wei; Pechmann, Cornelia (Elsevier Inc., 2019)
      The effects of hyperopia and frugality on spending have not been directly compared. Moreover, previous research on hyperopia has focused on the avoidance of luxury spending, rather than spending on routine consumer goods. ...
