A structure-based proposal for a comprehensive myotoxic mechanism of phospholipase A2-like proteins from viperid snake venoms
(Biochimica et Biophysica Acta - Proteins and Proteomics 1844(12):2265-2276, 2014-12)
Envenomation via snakebites is an important public health problem in many tropical and subtropical countries that, in addition to mortality, can result in permanent sequelae as a consequence of local tissue damage, which ...
Mortality due to snakebite envenomation in Costa Rica (1993–2006)
(2008-09-01)
The mortality due to snakebite envenomation in Costa Rica for the period 1993–2006 was investigated by a retrospective analysis. There were 48 fatalities due to snakebites during this period. Mortality rates ranged from ...
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. ...
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 ...
Increments in serum cytokine and nitric oxide levels in mice injected with Bothrops asper and Bothrops jararaca snake venoms
(2000-09)
Changes in serum levels of several cytokines and nitric oxide were studied in BALB/c mice injected intraperitoneally with one median lethal dose (LD(50)) of the venoms of Bothrops asper and Bothrops jararaca, two of the ...
Detection of rickettsiae in fleas and ticks from areas of Costa Rica with history of spotted fever group rickettsioses
(2016-10)
Outbreaks of spotted fevers have been reported in Costa Rica since the 1950s, although vectors responsible for transmission to humans have not been directly identified. In this study, species of Rickettsia were detected ...
Isolation and characterization of four medium-size disintegrins from the venoms of Central American viperid snakes of the genera Atropoides, Bothrops, Cerrophidion and Crotalus
(2014-12)
Four disintegrins were isolated from the venoms of the Central American viperid snakes Atropoides mexicanus (atropoimin), Bothrops asper (bothrasperin), Cerrophidion sasai (sasaimin), and Crotalus simus (simusmin). ...
Evaluación de la capacidad de cuatro antivenenos comerciales para neutralizar el veneno de la serpiente Bothrops asper (terciopelo) de Costa Rica
(1995-09)
We studied the ability of four commercially available antivenoms to neutralize several toxic and enzymatic activities of Bothrops asper (terciopelo) venom from Costa Rica. Experiments with preincubation of venom and antivenom ...
Pharmacokinetic-pharmacodynamic relationships of immunoglobulin therapy for envenomation.
(2003-07)
Parenteral administration of horse- and sheep-derived antivenoms constitutes the cornerstone in the therapy of envenomations induced by animal bites and stings. Depending on the type of neutralising molecule, antivenoms ...
