Proteomics of Wound Exudate in Snake Venom-Induced Pathology: Search for Biomarkers To Assess Tissue Damage and Therapeutic Success
(2011-02-10)Tissue damage analysis by traditional laboratory techniques is problematic. Proteomic analysis of exudates collected from affected tissue constitutes a powerful approach to assess tissue alterations, since biomarkers ... -
Protocolo nacional de vigilancia, atención y control del cólera (2022)
(2022)El cólera es una de las enfermedades más antiguas de la humanidad, pero es hasta inicios del siglo XIX que se dispone de un mayor conocimiento de sus causas, formas de transmisión y tratamiento. El mecanismo de transmisión ... -
Protocolo nacional para la vigilancia de enfermedades transmitidas por alimentos y agua
(2024)Las enfermedades transmitidas por los alimentos (ETA) constituyen un importante problema de salud a nivel mundial. Son provocadas por el consumo de agua o alimentos contaminados con microorganismos o parásitos, o bien ... -
Providing an in vitro depiction of microglial cells challenged with immunostimulatory extracellular vesicles of Naegleria fowleri
(2024)Naegleria fowleri is the causative agent of primary amoebic meningoencephalitis, a rapid and acute infection of the central nervous system with a fatal outcome in >97% of cases. Due to the infrequent report of cases and ... -
Prueba ESBL del sistema automatizado vitek®2 de Biomérieux como herramienta para la determinación del fenotipo BLEE en cepas de Enterobacter spp., Citrobacter spp., Proteus spp., Morganella spp. y Klebsiella aerogenes aisladas en el Hospital México durante el año 2021
(2023)Las betalactamasas de espectro extendido (BLEE) corresponden a enzimas catalíticas capaces de hidrolizar el enlace amídico del anillo betalactámico de penicilinas, cefalosporinas, con excepción de las cefamicinas; y los ... -
Psychosocial and sociocultural characteristics of Nicaraguan and Costa Rican students in the context of intercultural education in Costa Rica
(2018-05-31)This article examines problems and difficulties encountered by Nicaraguan migrant students in the Costa Rican educational system and contrasts their psychosocial and sociocultural well-being with their Costa Rican ... -
Pulmonary hemorrhage induced by jararhagin, a metalloproteinase from Bothrops jararaca snake venom
(2003-11-15)Jararhagin is the most important hemorrhagic component in the venom of the snake Bothrops jararaca, a species of medical importance in South America. It is a P-III zinc-dependent metalloproteinase comprising catalytic, ... -
Purification and characterization of BaH4, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(2000-01)A hemorrhagic metalloproteinase, named BaH4, was isolated from the venom of the snake Bothrops asper by a combination of ion-exchange chromatography on DEAE-Sepharose and gel filtration on Sephacryl S-200. BaH4 is a 69 kDa ... -
Purification and characterization of myotoxin IV, a phospholipase A2 variant, from Bothrops asper snake venom
(1995)A basic myotoxic protein was purified from Bothrops asper venom. Like other basic Bothrops myotoxins, myotoxin IV induces acute muscle damage after intramuscular injection in mice and disrupts negatively charged liposomes ... -
Purification of equine whole IgG snake antivenom by using an aqueous two phase system as a primary purification step
(2015-01)There is a need to introduce innovations in the manufacture of snake antivenoms to increase the supply of these products worldwide. In this work, the fractionation of equine hyperimmune plasma with a new methodology that ... -
Purification of IgG and albumin from human plasma by aqueous two phase system fractionation
(2012-08)The current shortages in human plasma products at global levels justify the development of new, cost effective plasma fractionation methods. We have developed a fractionation process to obtain immunoglobulin G (IgG) and ... -
Quantification of snake venom proteomes by mass spectrometry-considerations and perspectives.
(2023-05-08)The advent of soft ionization mass spectrometry-based proteomics in the 1990s led to the development of a new dimension in biology that conceptually allows for the integral analysis of whole proteomes. This transition from ... -
Quantitation by enzyme-immunoassay of antibodies against Bothrops myotoxins in four commercially-available antivenoms
(1991)An enzyme-immunoassay (EIA) for the quantitation of antibodies against myotoxins present in the venoms of Bothrops asper (Costa Rica), B. atrox (Colombia) and B. moojeni (Brazil), was developed. This EIA was utilized for ... -
