(2020)Las enfermedades gastrointestinales son una de las principales causas de morbilidad y mortalidad en países en vías de desarrollo. Las infecciones causadas por los diversos patotipos de E. coli diarreogénicas tienen alta ... -
La pertinencia de las ciencias sociales, en la investigación y la educación en salud, desde una mirada cualitativa
(2018-09)En el marco de la teoría de los intereses constitutivos de saberes de Habermas, las ciencias de la salud no han sido posicionadas, de manera formal en ella para explicar, comprender y transformar sus objetos o fenómenos ... -
Perturbation-Based Modeling Unveils the Autophagic Modulation of Chemosensitivity and Immunogenicity in Breast Cancer Cells
(2021-09-18)In the absence of new therapeutic strategies, chemotherapeutic drugs are the most widely used strategy against metastatic breast cancer, in spite of eliciting multiple adverse effects and having low responses with an ... -
Pesticide occurrence and water quality assessment from an agriculturally influenced Latin-American tropical region
(2021-01)A monitoring study was carried out in three agriculturally influenced microcatchments in Costa Rica during 2012e2014, for pesticides and water quality parameters. A total of 42 pesticides were analyzed, detecting the ... -
Pharmacokinetic-pharmacodynamic relationships of immunoglobulin therapy for envenomation.
(2003-07)Parenteral administration of horse- and sheep-derived antivenoms constitutes the cornerstone in the therapy of envenomations induced by animal bites and stings. Depending on the type of neutralising molecule, antivenoms ... -
Pharmacokinetics of whole IgG equine antivenom: comparison between normal and envenomed rabbits
(2006-09-01)Pharmacokinetics of antivenoms has been mainly studied in normal animals, whereas very little is known on pharmacokinetics in envenomed animals. The aim of this study was to compare pharmacokinetic parameters of whole IgG ... -
Pharmacological modulation of edema induced by Lys-49 and Asp-49 myotoxic phospholipases A2 isolated from the venom of the snake Bothrops asper (terciopelo)
(1998-12)The pharmacological modulation of edema-forming activity of Bothrops asper myotoxins II and III, Lys-49 and Asp-49 phospholipases A2, respectively, was studied plethysmographically in the mouse foot pad model. Myotoxin III ... -
Pharmacological modulation of hyperalgesia induced by Bothrops asper (terciopelo) snake venom
(2001-08)The ability of Bothrops asper snake venom to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of the venom (5–15 μg/paw) caused a dose and time-related hyperalgesia, which ... -
Pharmacological study of edema induced by venom of the snake Bothrops asper (terciopelo) in mice
(1995-01)The effect of several drugs on the edema-forming activity of Bothrops asper venom was studied plethysmographically using the mouse foot pad assay. Bothrops asper venom induced a dose-dependent edema which developed rapidly ... -
Phenotypes controlled by the Brucella abortus two component system BvrR/BvrS are differentially impacted by BvrR phosphorylation
(2023-04)Brucella abortus is a zoonotic pathogen whose virulence depends on its ability to survive intracellularly at the endoplasmic reticulum derived compartment. The two-component system BvrR/BvrS (BvrRS) is essential for ... -
Phenotypic and Genotypic Characterization of Multidrug-Resistant Bacteroides, Parabacteroides spp., and Pseudoflavonifractor from a Costa Rican Hospital
(2014-09)Multidrug resistance in Bacteroides spp. and related genera is uncommon and has not been described in Latin America until now. We studied phenotypically and genotypically the multidrug resistance of 10 clinical strains of ... -
Phenotypic identification of over 1000 isolates of anaerobic bacteria recovered between 1999 and 2008 in a major Costa Rican hospital
(2011-07)Because of limitations in infrastructure, the aetiology of infections caused by anaerobic bacteria is seldom determined in clinical laboratories of developing countries. This study reports on the identification of 1010 ... -
Phosphatidylinositol 3-Kinase/Akt Pathway Targets Acetylation of Smad3 through Smad3/CREB-binding Protein Interaction: Contribution to transforming growth factor 1-induced epstein-barr virus reactivation
(THE JOURNAL OF BIOLOGICAL CHEMISTRY 284(36), pp. 23912–23924, 2009-09-04)Epstein-Barr virus, a ubiquitous human herpesvirus, is associated with the development of carcinomas and lymphomas. We previously showed that transforming growth factor 1 (TGF- 1) mediated the virus to enter the lytic ... -
Phospholipase A2 and inflammation
