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 ...
An electrophoretic study on phospholipase A2 isoenzymes in the venoms of Central American crotaline snakes
(1992)
The number and isoelectric points of phospholipase A2 isoenzymes were studied in the venoms of 12 Central American crotaline snakes of the genera Bothrops, Crotalus, Lachesis and Agkistrodon. The study was carried out by ...
Neutralization of myotoxic phospholipases A2 from the venom of the snake Bothrops asper by monoclonal antibodies
(1992)
The neutralization of two myotoxic phospholipases A2 from the venom of Bothrops asper, myotoxins I and II, by two murine monoclonal antibodies is reported. The monoclonal antibodies, MAb-3 and Mab-4, recognize different ...
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 ...
Molecular Characterization of Two Major Dengue Outbreaks in Costa Rica
(2016-07)
Dengue virus (DENV) (Flavivirus, Flaviviridae) is a reemerging arthropod-borne virus with a worldwide
circulation, transmitted mainly by Aedes aegypti and Aedes albopictus mosquitoes. Since the first detection of its ...
Skeletal muscle degeneration and regeneration after injection of bothropstoxin-II, a phospholipase A2 isolated from the venom of the snake Bothrops jararacussu
(1991)
A myotoxic phospholipase A2, named bothropstoxin II (BthTX-II), was isolated from the venom of the South American snake Bothrops jararacussu and the pathogenesis of myonecrosis induced by this toxin was studied in mice. ...
Exposure of dogs to spotted fever group rickettsiae in urban sites associated with human rickettsioses in Costa Rica
(2016-07)
The zoonotic transmission cycles of Rickettsia rickettsii and other spotted fever group (SFG) rickettsiae
in Latin America have usually been associated with rural or sylvatic environments, although domestic
dogs can be ...
Ultrastructural alterations in mouse capillary blood vessels after experimental injection of venom from the snake Bothrops asper (Terciopelo)
(1992-10)
Histological and ultrastructural alterations in capillary blood vessels were studied at various time intervals after im injection of 50 micrograms of Bothrops asper snake venom in mouse gastrocnemius muscle. Hemorrhage was ...
Experimental myonecrosis induced by the venoms of South American Micrurus (coral snakes)
(1992)
Venoms from 11 taxa of Micrurus (coral snakes) from Brazil and Colombia were tested for myotoxic activity in mice. All venoms, except that of M. surinamensis, induced myotoxicity as judged by the increase in plasma creatine ...
The effect of myotoxins isolated from Bothrops snake venoms on multilamellar liposomes: relationship to phospholipase A2, anticoagulant and myotoxic activities
(1991-12)
The effect of four myotoxins isolated from Bothrops snake venoms on the release of peroxidase trapped in large multilamellar liposomes was studied and correlated to their phospholipase A2, myotoxic and anticoagulant ...
