Highly individual patterns of virus‑immune IgG effector responses in humans
(2016-05-18)t IgG responses are fundamental to adaptive immunity and document immunological memory of previous pathogen encounter. While specific antigen recognition is mediated by the variable F(ab′)2 domain of IgG, various effector ... -
Hiperfibrinólisis: mecanismos fisiopatológicos, métodos diagnósticos y tratamiento
(2021-07)En las últimas décadas, con el incremento de los procedimientos médicos mayores como cirugías cardíacas, trasplantes de órgano sólido, y de los accidentes en carretera, la importancia de la hiperfibrinólisis se ha hecho ... -
Histopathological and biochemical alterations induced by intramuscular injection of Bothrops asper (terciopelo) venom in mice
(1989)The local and systemic pathological changes induced by an i.m. injection of 100 micrograms of Bothrops asper venom in mice were studied histologically and by following the changes in serum levels of enzymes, proteins, ATP ... -
La Homocisteína como nuevo factor de riesgo cardiovascular
(2004)En la actualidad se tiene un amplio conocimiento de los factores de riesgo asociados con esta enfermedad. Sin embargo, las causas que inducen el inicio del proceso patológico aún son motivo de discusión. Los factores de ... -
Homogenates of skeletal muscle injected with snake venom inhibit myogenic differentiation in cell culture
(2013-02)Introduction: Viperid snakebite envenomings are characterized by muscle necrosis and a deficient regenerative response. Methods: Homogenates from gastrocnemius muscles of mice injected with the venom of the snake Bothrops ... -
Horse IgG isotypes and cross-neutralization of two snake antivenoms produced in Brazil and Costa Rica
(2000-05)Horse IgG isotypes and cross-neutralization of two snake antivenoms produced in Brazil and Costa Rica. Toxicon 000–000. This work compared the specificity, ELISA titers and IgG subclass content of the polyvalent antivenom ... -
Horse immunization with short-chain consensus α-neurotoxin generates antibodies against broad spectrum of elapid venomous species
(2019)Antivenoms are fundamental in the therapy for snakebites. In elapid venoms, there are toxins, e.g. short-chain α-neurotoxins, which are quite abundant, highly toxic, and consequently play a major role in envenomation ... -
Host response to Bothrops asper snake venom: analysis of edema formation, inflammatory cells, and cytokine release in a mouse model
(1993)As part of tle characterization of the host reactivity to the venom of Bothrops asper, we investigated the inflammatory responses in the mouse footpad model. The subcutaneously iniected venom induced a rapid increase of ... -
Host-Feeding Patterns of the Mosquito Assemblage at Lomas Barbudal Biological Reserve, Guanacaste, Costa Rica
(2021-07)Mosquito-borne pathogens have spread throughout tropical regions of the Western Hemisphere causing increased burden of disease in the region. Outbreaks of dengue fever, yellow fever, chikungunya, West Nile, and Zika have ... -
Human Cytomegalovirus Fcγ Binding Proteins gp34 and gp68 Antagonize Fcγ Receptors I, II and III
(2014-05-15)Human cytomegalovirus (HCMV) establishes lifelong infection with recurrent episodes of virus production and shedding despite the presence of adaptive immunological memory responses including HCMV immune immunoglobulin G ... -
Human heterophilic antibodies against equine immunoglobulins: assessment of their role in the early adverse reactions to antivenom administration
(2008)The presence of human heterophilic antibodies against horse immunoglobulins (HHA-HI) was determined by ELISA in sera from healthy volunteers and from patients who received equine antivenom for therapy of snake bite ... -
Hybrid mathematical modeling decodes the complexity of sphingolipid pathway to predict chemosensitivity
(2017)Sphingolipid (SL) signaling pathway is a complex biological system able to integrate different types of cellular stress signals related to induction of cell death pathways with special interest in cancer. This makes of ... -
Hydrocarbon Degrading Microflora in a Tropical fuel-Contaminated Aquifer: Assessing the Feasibility of PAH Bioremediation
(2012-01)An aquifer located within a petroleum processing plant in Moín, Costa Rica, suffers hydrocarbon pollution. This study aimed to determine the ability of indigenous microorganisms from this site to degrade polycyclic ... -
Hydrology Affects Environmental and Spatial Structuring of Microalgal Metacommunities in Tropical Pacific Coast Wetlands
(2016-02-22)The alternating climate between wet and dry periods has important effects on the hydrology and therefore on niche-based processes of water bodies in tropical areas. Additionally, assemblages of microorganism can show spatial ... -
Hyperalgesia induced by Asp49 and Lys49 phospholipases A2 from Bothrops asper snake venom: pharmacological mediation and molecular determinants
(2003-05)The ability of Lys49 and Asp49 phospholipases A2 (PLA2), from Bothrops asper snake venom, to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of both toxins (5–20 μg/paw) ... -
