A long-standing question in evolutionary studies of snake venoms is the extent to which phylogenetic divergence and diet can account for between-species differences in venom composition. Here we apply phylogeny-based comparative methods to address this question. We use data on venom variation generated using proteomic techniques for all members of a small clade of rattlesnakes (Sistrurus sp.) a...
UNLABELLED Snake venoms undergo ontogenetic shifts in biochemical and pharmacological activities. This may be related to variation in venom components associated with the ontogenetic shift in diet. We used the short-tailed pit viper Gloydius brevicaudus that displays ontogenetic shifts in diet to examine whether the species displays a neonate-to-adult transition of snake venomics. Venoms from n...
BACKGROUND Snake bite causes greater mortality than most of the other neglected tropical diseases. Snake antivenom, although effective in minimizing mortality in developed countries, is not equally so in developing countries due to its poor availability in remote snake infested areas as, and when, required. An alternative approach in this direction could be taken by making orally deliverable po...
Introduction: Venoms are a mixture of proteins and peptides which can be used for fighting cancers. They can affect the exposed fibers and the muscles directly or through motor nerves, causing neuromuscular intoxication. ICD-85 is a combination of three poly-peptides derived from the venoms of an Iranian brown snake and a yellow scorpion. Materials and Methods...
The antivenom properties of methanolic extract of Ficus iteophylla miq and Borassus aethiopum plants were investigated against the venom of Naja mossandica snake. Both plant extracts effectively reduced the Naja mossandica venom induced hemolytic activity. The result reveals that hemolysis due to venom was 81.5% without extract but the heomolytic activity was drastically reduced by Ficus iteoph...
The enzyme L-Amino Acid Oxidase (LAAO) is widely distributed in snake venoms, contributes a reasonable toxicity to the venoms. However LAAO from Indian cobra (Naja naja ) snake venom has not yet isolated previously. In the present study LAAO from Indian cobra (Naja naja ) snake venom was purified by sequential steps of cation exchange chromatography (CM-Sephadex C-25; CM-52 cellulose), followed...
In vitro activity of isolated fractions from Iranian cobra snake venom against Plasmodium falciparum
Australia is the stronghold of the front-fanged venomous snake family Elapidae. The Australasian elapid snake radiation, which includes approximately 100 terrestrial species in Australia, as well as Melanesian species and all the world's sea snakes, is less than 12 million years old. The incredible phenotypic and ecological diversity of the clade is matched by considerable diversity in venom co...
The snake venom´s thrombin-like enzymes comprise a number of serine proteases, which are functionally and structurally related to thrombin. Purification and partial characterization of a thrombin-like enzyme from the venom of the Iranian snake, Agkistrodon halys, was the aim of this study. Purification was carried out by a combination of variety of chromatographic methods that included: gel...
BACKGROUND Snake bite is a neglected public health problem in communities in rural areas of several countries. Bothrops jararaca causes many snake bites in Brazil and previous studies have demonstrated that the pharmacological activities displayed by its venom undergo a significant ontogenetic shift. Similarly, the venom proteome of B. jararaca exhibits a considerable variation upon neonate to ...
