Venoms of several animals have been used to study various physiopathologic processes, and also to offer opportunity to design and develop new therapeutic drugs. We briefly review certain wasp venom components and their biological effects,... more
As viper snake bites are the most important cause of snake-bite mortality in several places of the world, the present study spotlighted this type of snake bites among snakebites patients received at the Poison Control Center, Ain Shams... more
Cnidarian envenomations are the leading cause of severe and lethal human sting injuries from marine life. The total amount of venom discharged into sting-site tissues, sometimes referred to as " venom load " , has been previously shown to... more
The LD50 is an important metric for venom studies and antivenom development. It has been shown that several variables in the protocol influence the LD50 value obtained, such as venom source, extraction and treatment and administration... more
Cubozoa-class cnidarian (box jellyfi sh) envenomations constitute a complex medical challenge and public health threat. There are currently no validated standards of care for life-threatening stings. Increasing numbers and reported... more
A host-specific wasp parasitising the redback spider implies that the spider is native to Australia
Toxins and venom components that target voltage-gated sodium (NaV) channels have evolved numerous times due to the importance of this class of ion channels in the normal physiological function of peripheral and central neurons as well as... more
Ecuador harbors one of the most diverse Neotropical scorpion faunas, hereby updated to 47 species contained within eight genera and five families, which inhabits the “Costa” (n = 17), “Sierra” (n = 34), “Oriente” (n = 16) and “Insular” (n... more
Enzyme-cleaved antibodies are used widely for the treatment of envenoming. Such products should comprise only ‘highly pure’ immunoglobulin fragments since Fc or other contaminating protein fragments or their aggregates may lead to side... more
While snake venoms have been the subject of intense study, comparatively little work has been done on lizard venoms. In this study, we have examined the structural and functional diversification of anguimorph lizard venoms and associated... more
A B S T R A C T A paradigm of venom research is adaptive evolution of toxins as part of a predator-prey chemical arms race. This study examined differential co-factor dependence, variations relative to dietary preference, and the impact... more
Centruroides tecomanus is a medically important scorpion of the state of Colima (Mexico). This communication reports the identification of venom components of this scorpion with biological activity over insects/crickets (Acheta... more
The use of California harvester ants (Pogonomyrmex californicus) for visionary and therapeutic ends was an important but poorly-documented tradition in native south-central California. In this brief report, a confirmation of the... more
The Asian genus Boiga (Colubridae) is among the better studied non-front-fanged snake lineages, because their bites have minor, but noticeable, effects on humans. Furthermore, B. irregularis has gained worldwide notoriety for successfully... more
Toxic weaponry in the form of venom and poison has evolved in most groups of animals, including all four major lineages of tetrapods. Moreover, the evolution of such traits has been linked to several key aspects of the biology of toxic... more
