Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus
(2022)
The subgenus Tityus (Archaeotityus) includes small variegated species considered until recently, a basal group within Tityus, one of the most diverse and medically relevant genera of scorpions in the New World. Archaeotityus ...
Neutralization of Bothrops asper venom by antibodies, natural products, and synthetic drugs: contributions to understanding snakebite envenomings and their treatment
(2009)
Interest in studies on the neutralization of snake venoms and toxins by diverse types of
inhibitors is two-fold. From an applied perspective, results enclose the potential to be
translated into useful therapeutic products ...
Venom characterization of the bark scorpion Centruroides edwardsii (Gervais 1843): composition, biochemical activities and in vivo toxicity for potential prey
(2019)
In this study, we characterize the venom of Centruroides edwardsii, one of the most abundant scorpions in urban
and rural areas of Costa Rica, in terms of its biochemical constituents and their biological activities. C. ...
Biochemical characterization of the venom of Central American scorpion Didymocentrus krausi Francke, 1978 (Diplocentridae) and its toxic effects in vivo and in vitro
(2019)
non-buthid venoms, for which knowledge is scarce. In this work, we characterized the venom of a Diplocentridae
species, Didymocentrus krausi, a small fossorial scorpion that inhabits the Tropical Dry Forest of Central ...
Comparative study of synthetic peptides corresponding to region 115-129 in Lys49 myotoxic phospholipases A2 from snake venoms
(2003)
Lys49 phospholipase A2 homologues constitute a group of catalytically-inactive proteins, present in the venoms of many
crotalid snakes, which induce myonecrosis. Current evidence supports the mapping of their toxic site ...
Isolation and characterization of basic myotoxic phospholipases A2 from Bothrops godmani (Godman's pit viper) snake venom
(1992)
Two basic myotoxic phospholipases A2 were purified to homogeneity from the venom of Bothrops godmani from Costa Rica by ion-exchange chromatography on CM-Sephadex. They have molecular weights of 14,300 (myotoxin I) and ...
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, ...
Comparison of biochemical and cytotoxic activities of extracts obtained from dorsal spines and caudal fin of adult and juvenile non-native Caribbean lionfish (Pterois volitans/miles)
(2017-10)
Pterois volitans/miles lionfish (adult and juvenile) dorsal spines and caudal fin extracts were compared in
their general composition, enzymatic activities and hemolytic and cytotoxic effects on bovine aortic
endothelial ...
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 ...
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, ...
