Sulfated polysaccharides (SPs) are abundant in seaweed and have several industrial and biomedical applications, but their renal effects remain unclear. This study evaluated the effects of total sulfated polysaccharides (TSPs) from Gracilaria cornea u...
Anecdotal reports have recently circulated suggesting that intramuscular injection of bacteriostatic saline (BS)—which contains benzyl alcohol (BnOH)—can reverse botulinum toxin type A (BoNTA)-induced brow ptosis. Given the well-establish...
Scorpion venoms contain a wide range of toxins that interact with a variety of target molecules (ion channels, receptors and enzymes) associated with synaptic transmission, action potential propagation, cardiac function, hemostasis and other physiolo...
The puff adder (Bitis arietans) is a clinically relevant viper species found throughout Africa, and it is responsible for a greater incidence of health-related envenomations than all other snake species on the continent combined. Unresolved skeletal...
Alexandrium spp. blooms produce a range of toxins, including spirolides, goniodomins, and paralytic shellfish toxins (PSTs). Of these, PSTs are the most impactful due to their high affinity for voltage-gated sodium ion channels in nerve cell membrane...
Plant-derived toxins such as ricin and abrin represent some of the most potent biological agents known, posing significant threats to public health and security due to their high toxicity, relative ease of extraction, and widespread availability. The...
