Background Snake venoms are complex mixtures of inorganic and organic components, mainly proteins and peptides. Standardization of methods for isolating bioactive molecules from snake venoms is extremely difficult due to the complex and highly variable composition of venoms, which can be influenced by fa...
Background Phospholipases A 2 (PLA 2 s) are abundant components of snake venoms that have been extensively studied due to their pharmacological and pathophysiological effects on living organisms. This study aimed to assess the antitumor potential of BthTX-I, a basic myotoxic PLA 2isolated from Bothrops ...
Background Considering the similarity between the testis-specific isoform of angiotensin-converting enzyme and the C-terminal catalytic domain of somatic ACE as well as the structural and functional variability of its natural inhibitors, known as bradykinin-potentiating peptides (BPPs), the effects of di...
Ophidian accidents constitute a serious problem of public health in the tropical countries. In
Central and South America, most of the accidents are caused by Bothrops (90.5%), followed by the Crotalus (7.7%),
Lachesis (1.4%) and Micrurus (0.4%) genus. The aim of this work was to evaluate clinical-epidemi...
Background The search for new inhibitors of snake venom toxins is essential to complement or even replace traditional antivenom therapy, especially in relation to compounds that neutralize the local effects of envenomations. Besides their possible use as alternative to traditional antivenom therapy, some...
Background Hyaluronate is one of the major components of extracellular matrix from vertebrates whose breakdown is catalyzed by the enzyme hyaluronidase. These enzymes are widely described in snake venoms, in which they facilitate the spreading of the main toxins in the victim's body during the envenoming...
Background The testis-specific isoform of angiotensin-converting enzyme (tACE) is exclusively expressed in germ cells during spermatogenesis. Although the exact role of tACE in male fertility is unknown, it clearly plays a critical function in spermatogenesis. The dipeptidase domain of tACE is identical ...
La mordedura de serpientes constituye un problema de salubridad importante en muchos países tropicales y subtropicales, con un estimado de 2,5 millones de personas envenenadas cada año. En Colombia las especies Bothropsasper y Bothropsatrox son las causantes del 70 al 90 % de los accidentes registrados...
