(2019-01)El libro 'Reflexiones desde la academia. Universidad, ciencia y sociedad' recoge reflexiones relacionadas con la situación actual de las universidades públicas en América Latina y las encrucijadas por las que atraviesan ... -
Regional warming and the thermal regimes of American crocodile nests in the Tempisque Basin, Costa Rica
(2016-06-11)Spatial variation in global climate change makes population-specific responses to this enigmatic threat pertinent on a regional scale. Organisms with temperature-dependent sex determination (TSD) potentially possess a ... -
Relation of atrophic gastritis with Helicobacter pylori-CagA+ and interleukin-1 polymorphisms
(World Journal Gastroenterol 14(42), 2008-11-14)AIM: To determine the association of Helicobacter pylori (H pylori) CagA+ infection and pro-inflammatory polymorphisms of the genes interleukin (IL)-1RN and IL-1B with the risk of gastric atrophy and peptic ulcers in a ... -
Resistencia a insecticidas en cepas de Aedes aegypti (Diptera: Culicidae) de tres distritos de la Región Pacífico Central de Costa Rica
(2018-12-30)Introducción: Aedes aegypti es vector de virus dengue, chikungunya y Zika en Costa Rica. Su alta incidencia y carencia de vacunas hacen del control vectorial, incluyendo el químico, la única alternativa para disminuir su ... -

Resurrexit, sicut dixit, alleluia. Snake venomics from a 26-years old polyacrylamide focusing gel
(2012)A 26-year-old dried polyacrylamide gel, cast in presence of an immobilized pH gradient and containing focused proteins from the venoms of a northern black-tailed rattlesnake (Crotalus molossus molossus), and of a western ... -
Rickettsia felis in Ctenocephalides felis from Guatemala and Costa Rica
(2012)Rickettsia felis is an emerging human pathogen associated primarily with the cat flea Ctenocephalides felis.In this study, we investigated the presence of Rickettsia felis in C. felis from Guatemala and Costa Rica. ... -
Role of collagens and perlecan in microvascular stability: exploring the mechanism of capillary vessel damage by snake venom metalloproteinases
(2011-12-08)Hemorrhage is a clinically important manifestation of viperid snakebite envenomings, and is induced by snake venom metalloproteinases (SVMPs). Hemorrhagic and non-hemorrhagic SVMPs hydrolyze some basement membrane (BM) and ... -
Role of cyclooxygenases in oedema-forming activity of bothropic venoms
(2007-04)The venoms of Bothrops asper (BaV) and Bothrops jararaca (BjV), two of the most medically important poisonous snakes of Latin America, cause pronounced oedema in the victims through poorly understood mechanisms. In the ... -
Role of enzymatic activity inmuscle damage and cytotoxicity induced by Bothrops asper Asp49 phospholipase A2 myotoxins: are there additional effector mechanisms involved?
(Peer Journal 2:e569; DOI 10.7717/peerj.569, 2014-09-16)Viperid venoms often contain mixtures of Asp49 and Lys49 PLA2 myotoxin isoforms, relevant to development of myonecrosis. Given their difference in catalytic activity, mechanistic studies on each type require highly ... -
