Clinical and laboratory alterations in horses during immunization with snake venoms for the production of polyvalent (Crotalinae) antivenom
(1997-01)
Six horses were immunized with the venoms of Bothrops asper, Crotalus durissus durissus and Lachesis muta stenophrys for the production of polyvalent (Crotalinae) antivenom. During the immunization, clinical and laboratory ...
Immunochemical properties of the N-terminal helix of myotoxin II, a lysine-49 phospholipase A2 from Bothrops asper snake venom
(2001)
Myotoxic class II phospholipases A2 from snake venoms can be divided into Asp49 and Lys49 types. The latter, including
Bothrops asper myotoxin II, exert membrane damage despite lacking catalytic activity. A heparin-binding, ...
Inhibitory effect of fucoidan on the activities of crotaline snake venom myotoxic phospholipases A2
(2003)
Myotoxic phospholipases A2 account for most of the muscle necrosis that results from envenenomation by crotaline snakes. In this study,
we investigated the protective effect of fucoidan, a natural sulfated polysaccharide ...
Método para la producción de formulaciones inyectables de productos proteicos hemoderivados y productos obtenidos utilizando dicho método
(2011-04-08)
The invention relates to a method for producing injectable pharmaceutical formulations of blood-derived protein materials, including the steps of fractioning the source material in a polymer/salt aqueous two-phasesystem ...
Characterization of a basic phospholipase A2-homologue myotoxin isolated from the venom of the snake Bothrops neuwiedii (yarará chica) from Argentina
(1999)
A basic protein was isolated by CM-Sephadex C-25 chromatography from the venom of
Bothrops neuwiedii from Argentina, and named B. neuwiedii myotoxin I. This protein
exerted local myotoxic and edema-forming e ects in mice, ...
Comparative study of the cytolytic activity of snake venoms from African spitting cobras (Naja spp., Elapidae) and its neutralization by a polyspecific antivenom
(2011-11)
Venoms of several Naja species found in Sub-Saharan Africa, and commonly known as "spitting cobras", induce a predominantly cytotoxic pattern of envenomings that may evolve into tissue necrosis and gangrene. Cytotoxic ...
Isolation and characterization of myotoxin II from Atropoides (Bothrops) nummifer snake venom, a new Lys49 phospholipase A2 homologu
(2000)
Myotoxic phospholipases A2 of class II are commonly found in the venoms of crotalid snakes. As an approach to
understanding their structure±activity relationship, diverse natural variants have been characterized ...
An overview of Lysine-49 phospholipase A2 myotoxins from crotalid snake venoms and their structural determinants of myotoxic action
(2003)
In 1984, the first venom phospholipase A2 (PLA2) with a lysine substituting for the highly conserved aspartate 49 was
discovered, in the North American crotalid snake Agkistrodon p. piscivorus [J. Biol. Chem. 259 (1984) ...
Screening for target toxins of the antiophidic protein DM64 through a gel-based interactomics approach
(2017-01)
DM64 is a glycosylated protein with antivenomactivity isolated fromthe serum of the opossumDidelphis aurita.
It binds non-covalently to myotoxins I (Asp49) and II (Lys49) from Bothrops asper venom and inhibits their
myotoxic ...
Synthetic peptides derived from the C-terminal region of Lys49 phospholipase A2 homologues from Viperidae snake venoms: biomimetic activities and potential applications
(2010)
Lys49-phospholipase A2 homologues constitute a large family of toxins present in the venoms of viperid snake species, which
despite lacking catalytic activity, cause significant skeletal muscle necrosis. The main structural ...
