Medicinal plants with inhibitory properties against snake venoms
(2005)
Envenomations due to snake bites are commonly treated by parenteral administration of horse or
sheep-derived polyclonal antivenoms aimed at the neutralization of toxins. However, despite the widespread
success of this ...
Increased Infectivity of Staphylococcus aureus in an Experimental Model of Snake Venom–Induced Tissue Damage
(2007-09-01)
Soft-tissue infection is commonly found in patients bitten by Latin American Bothrops snakes. Staphylococcus aureus, which is not present in the mouth of the snake, is frequently isolated from these infections. The effects ...
Pathological changes induced by BaH1, a hemorrhagic proteinase isolated from Bothrops asper (Terciopelo) snake venom, on mouse capillary blood vessels
(1994-08)
The pathological changes induced in capillaries by BaH1, a hemorrhagic metalloproteinase isolated from the venom of Bothrops asper, were studied after i.m. injection in mouse gastrocnemius. Hemorrhage was observed ...
Unresolved issues in the understanding of the pathogenesis of local tissue damage induced by snake venoms
(2018-06)
Snakebite envenoming by viperid species, and by some elapids, is characterized by a complex pattern of
tissue damage at the anatomical site of venom injection. In severe cases, tissue destruction may be so
extensive as ...
Hemorrhage induced by snake venom metalloproteinases: biochemical and biophysical mechanisms involved in microvessel damage
(2005-06-15)
Zinc-dependent metalloproteinases are responsible for the hemorrhagic activity characteristic of viperid snake venoms. Snake venom metalloproteinases (SVMPs) are classified in various groups (P-I–IV), according to their ...
Inhibitory effects of Piper umbellatum and Piper peltatum extracts towards myotoxic phospholipases A2 from Bothrops snake venoms: isolation of 4-nerolidylcatechol as active principle
(2005)
Phospholipases A2 (PLA2) are important constituents of snake venoms, being responsible for several of their toxic actions.
Extracts from plants used in folk medicine were screened for inhibition of the enzymatic activity ...
Strategies in 'snake venomics' aiming at an integrative view of compositional, functional, and immunological characteristics of venoms
(2017-04)
This work offers a general overview on the evolving strategies for the proteomic analysis of snake venoms, and
discusses how these may be combined through diverse experimental approaches with the goal of achieving a
more ...
Exploration of immunoglobulin transcriptomes from mice immunized with three-finger toxins and phospholipases A2 from the Central American coral snake, Micrurus nigrocinctus
(2017)
Snakebite envenomings represent a neglected public health issue in many parts of the
rural tropical world. Animal-derived antivenoms have existed for more than a hundred
years and are effective in neutralizing snake venom ...
N-terminal peptide of myotoxin II from Bothrops asper venom enhances the activity of endothelin converting enzyme and neprilysin
(2016)
Neprilysin (NEP) and endothelin converting enzyme-1 (ECE-1) are two enzymes that degrade amyloid
beta in the brain. Currently there are no molecules to stimulate the activity of these enzymes. Here
we report, the discovery ...
From Fangs to Pharmacology: The Future of Snakebite Envenoming Therapy
(2016)
The snake is the symbol of medicine due to its association with Asclepius, the
Greek God of medicine, and so with good reasons. More than 725 species of venomous
snakes have toxins specifically evolved to exert potent ...
