Cytotoxicity induced in myotubes by a Lys49 phospholipase A2 homologue from the venom of the snake Bothrops asper: Evidence of rapid plasma membrane damage and a dual role for extracellular calcium
(2007-12)
Acute muscle tissue damage, myonecrosis, is a typical consequence of envenomations by snakes of the family Viperidae. Catalytically-inactive Lys49 phospholipase A2 homologues are abundant myotoxic components in viperid ...
Ten simple rules for aspiring scientists in a low-income country
(PLOS Computational Biology, vol. 4, n. 5, e1000024, 2008, 2008)
Being a scientist entails a common set of characteristics. Admiring nature and having concern for social issues; possessing a strong academic background, team work abilities, honesty, discipline, skepticism, communication ...
Toxicity of Bothrops sp snake venoms from Ecuador and preclinical assessment of the neutralizing efficacy of a polyspecific antivenom from Costa Rica
(2014-09-15)
The toxicological profile of the venoms of the snakes Bothrops asper and Bothrops atrox from Ecuador was investigated, together with the venom of a population of B. asper formerly classified as ‘Bothrops xanthogrammus’. ...
Skeletal muscle degeneration induced by venom phospholipases A2: insights into the mechanisms of local and systemic myotoxicity
(2003-12)
Local and systemic skeletal muscle degeneration is a common consequence of envenomations due to snakebites and mass bee attacks. Phospholipases A2 (PLA2) are important myotoxic components in these venoms, inducing a similar ...
Neutralization of crotaline snake venoms from Central and South America by antivenoms produced in Brazil and Costa Rica
(2000-10)
A study was performed on the ability of antivenoms, produced in Brazil and Costa Rica, to neutralize lethal, hemorrhagic and coagulant activities of the venoms of 16 species of Central and South American snakes of the ...
Evaluation of the neutralizing ability of antivenoms for the treatment of snake bite envenoming in Central America
(1996)
De nombreuses envenimations ophidiennes en Amérique centrale sont dues aux crotales (famille des Viperidae) parmi lesquels Bothrops asper est le principal responsable. Quelques accidents sont provoqués par les serpents ...
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 ...
A neutralizing recombinant single chain antibody, scFv, against BaP1, A P-I hemorrhagic metalloproteinase from Bothrops asper snake venom
(2014-09-01)
BaP1 is a P-I class snake venom metalloproteinase (SVMP) relevant in the local tissue damage associated with envenomings by Bothrops asper, a medically important snake species in Central America and parts of South and North ...
Membrane independent activation of fibroblast proMMP-2 by snake venom: novel roles for venom proteinases
(2004-12-01)
ProMMP-2 activation by Bothrops asper venom was investigated in mouse gastrocnemius muscle, mammalian cell culture and a cell-free system. Zymography revealed an increment of latent and activated forms of MMP-2 in muscle ...
Preclinical evaluation of three polyspecific antivenoms against the venom of Echis ocellatus: Neutralization of toxic activities and antivenomics
(2016-09-01)
Snakebite envenoming has a heavy burden in the public health in sub-Saharan Africa. The viperid species Echis ocellatus (carpet viper or saw-scaled viper) is the medically most important snake in the savannahs of western ...
