Scorpion venom phospholipases A2: A minireview

Toxicon, 2020
Many venomous species, including snakes, bees and scorpions, contain a variety of secreted phospholipases A2 (sPLA2) that contribute to prey digestion and venom toxicity. Based on their primary structures, the different venom sPLA2 have been classified into four groups I, II, III and IX.

Snapshots of scorpion venomics

Journal of Arid Environments, 2015
Scorpions are particularly well adapted to survival in extreme habitats (especially arid and semi-arid environments) and their ability to produce and deliver venoms is an important factor in this success. Scorpion venoms are very complex mixtures of different proteins and peptides.

Physiological Action of Scorpion Venom

The American Journal of Tropical Medicine and Hygiene, 1960
Summary Venom of the scorpion, Centruroides sculpturatus Ewing, caused hypertension, respiratory failure, and skeletal muscle stimulation in anesthetized animals. No significant action of the venom was found on isolated skeletal muscle preparations.

The effect of scorpion venom on blowfly larvae—A new method for the evaluation of scorpion venoms potency

Toxicon, 1971
The injection of small amounts of scorpion venom in blowfly larvae causes an immediate contraction and paralysis, the duration of which is dosage dependent. This response of fly larvae, considered to represent a peripheral neurotoxic effect of scorpion venoms, is suggested as a rapid and sensitive test for the quantitative estimation of the potency of ...

THE EFFECTS OF SCORPION VENOM

The Canadian Entomologist, 1901
The prevailing belief in regard to scorpion stings seems to be correct: dangerons, but seldom fatal.However, there are scorpions and scorpions. Moreover, much depends upon the season and the part stung. Generally speaking, a sting in the dry season is much worse than one in the rainy season, because the venom becomes concentrated during the period of ...

Modern Venom Profiling: Mining into Scorpion Venom Biodiversity

2014
Scorpions and their sting are infamous for causing pain, morbidity, and, in some cases, death. However, research into scorpion venoms has revealed the presence of components that potentially have beneficial properties for humans. Such components may be developed into therapeutics or bioinsecticides.
