(2002-06-01)Se realizó una encuesta entomológica en 157 viviendas pertenecientes a cuatro zonas de la Meseta Central de Costa Rica, donde la enfermedad de Chagas es endémica. Trece casas (8,3%) presentaron una infestación positiva por ... -
Infiltración y redistribución de agua en perfiles de la zona no saturada en la cuenca alta del río Paez, Cartago
(2022)En Costa Rica, la entrada del agua al suelo y su movimiento dentro de él ha sido poco estudiado. Esta entrada de agua puede estudiarse en un espacio geográfico claramente definido como lo es la cuenca hidrográfica. Es ... -
La inflamacion y su papel en el desarrollo del cáncer gástrico
(Acta Medica Cnstarricense Vol 51 (2):76-82, abril-junio 2009, 2009-04)La infección por Helicobacter pylori produce, en algunos pacientes, inflamación crónica en el estómago, gastritis atrófica y cáncer gástrico. Los mecanismos moleculares que conducen de la infección a la inflamación crónica ... -
Inflammation and uPAR-Expression in Colorectal Liver Metastases in Relation to Growth Pattern and Neo-adjuvant Therapy
(2015-08-14)Proteolytic activity and inflammation in the tumour microenvironment affects cancer progression. In colorectal cancer (CRC) liver metastases it has been observed that three different immune profiles are present, as well ... -
Inflammation induced by Bothrops asper venom: release of proinflammatory cytokines and eicosanoids, and role of adhesion molecules in leukocyte infiltration
(2005-12)Bothrops asper venom (BaV) causes systemic and local effects characterized by an acute inflammatory reaction with accumulation of leukocytes and release of endogenous mediators. In this study, the effects of BaV on the ... -
Inflammatory effects of BaP1 a metalloproteinase isolated from Bothrops asper snake venom: leukocyte recruitment and release of cytokines
(2006-04)The inflammatory events induced by BaP1, a 22.7 kDa metalloproteinase isolated from Bothrops asper snake venom, were studied. BaP1 i.p. injection in mice induced a marked inflammatory cell infiltrate into peritoneal cavity ... -
Inflammatory events induced by Lys-49 and Asp-49 phospholipases A2 isolated from Bothrops asper snake venom: role of catalytic activity
(2005-03)The inflammatory events induced in the peritoneal cavity of mice by two PLA2s isolated from Bothrops asper snake venom were investigated. MT-III, an Asp-49 catalytically active enzyme and MT-II, a catalytically inactive ... -
Inflammatory infiltrate in skeletal muscle injected with Bothrops asper venom
(1986)The time-course and composition of inflammatory infiltrate in mouse gastrocnemius injected with Bothrops asper venom was studied. The venom induced myonecrosis, and a prominent decrease in muscle levels of creatine kinase ... -
Influence of bitumen and aggregate polarity on interfacial adhesion
(2017)The quality of the bitumen–aggregate interface formed in an asphalt mixture is dictated by the physicochemical properties of both materials, such as surface polarity. In order to better understand the role of polarity on ... -
