Effects of a myotoxic phospholipase A2 isolated from Bothrops asper venom on skeletal muscle sarcoplasmic reticulum
(1987)
The myotoxin from B. asper snake venom inhibited Ca-ATPase activity of rabbit sarcoplasmic reticulum after incubation in vitro. Inhibition was non-competitive and albumin enhanced the effect of the toxin. Furthermore, B. ...
Niveles de inmunoglobulinas séricas (IgG, IgA e IgM) en adultos jóvenes sanos, por el método de inmunodifusión radial
(1985)
Se determinó la concentración de IgG, IgA, e IgM en el suero de 49 estudiantes universitarios normales, de 18 a 25 años. Para esto se empleó el método de inmunodifusión radial, en placas comerciales. Los resultados fueron ...
Edema-forming activity of bushmaster (Lachesis muta stenophrys) and Central American rattlesnake (Crotalus durissus durissus) venoms and neutralization by a polyvalent antivenom
(1985)
The edema effect induced in mice by venoms of Crotalus durissus durissus and Lachesis muta stenophrys was studied . Minimum edema-forming doses were 11 and 5 ug, respectively . Edema developed very rapidly after injections ...
Porcentaje y cifra absoluta de linfocitos T en sangre periférica por el método de rosetas E: estudio de cuarenta adultos sanos
(1985)
Se realizó la determinación del porcentaje y cifra absoluta de linfocitos T en sangre periférica a un grupo de 40 adultos sanos costarricenses, seleccionados de un grupo inicial de 58 voluntarios. Se utilizó un método de ...
Producción de placas de inmunodifusión radial para la cuantificación de IgG humana
(1985)
Se describe un método para la preparación de placas de inmunodifusión radial para la cuantificación de la lgG humana. El método se basó en las siguientes etapas: (1) aislamiento de lgG de suero normal
mediante cromatografía ...
DNase activity in Costa Rican crotaline snake venoms: quantification of activity and identification of electrophoretic variants.
(1991)
DNase activity of Costa Rican crotaline snake venoms from the genera Bothrops, Crotalus and Lachesis was quantified by an enzymodiffusion method on agarose/DNA gels containing ethidium bromide. The reaction is detected as ...
Isolation from a polyvalent antivenom of antibodies to a myotoxin in Bothrops asper snake venom
(1985)
Antibodies against Bothrops asper rmyotoxin were purified from a polyvalent antivenom by affinity chromatography . These antibodies neutralized most of the myotoxic activity of crude B. asper venom, as judged by histologic ...
Zika Virus (ZIKV): A New Emerging Pathogen Transmitted by Aedes Mosquitoes (Diptera: Culicidae) in the Latin American Subcontinent
(2016-03-11)
Aedes aegypti and Aedes albopictus (Diptera: Culicidae) are two
species of synanthropic mosquitoes that are common in outdoor
and indoor domiciliary environments in tropical countries. Their
vectorial competence and ...
Global genetic diversity of Aedes aegypti
(2016-11)
Mosquitoes, especially Aedes aegypti, are becoming important models for studying invasion biology. We characterized genetic variation at 12 microsatellite loci in 79 populations of Ae. aegypti from 30 countries in six ...
N-Formyl-Perosamine Surface Homopolysaccharides Hinder the Recognition of Brucella abortus by Mouse Neutrophils
(2016-06)
Brucella abortus is an intracellular pathogen of monocytes, macrophages, dendritic cells, and placental trophoblasts. This bacterium
causes a chronic disease in bovines and in humans. In these hosts, the bacterium also ...
