ACTIONS OF SCORPION VENOM ON SKELETAL MUSCLE [PDF]

open access: yesBritish Journal of Pharmacology and Chemotherapy, 1959
A protein‐like constituent of scorpion venom produced effects on the skeletal muscle fibre resembling those of citrate, lack of calcium or veratrine. These effects could be diminished by the addition of calcium. They do not appear to be due to the formation of a non‐ionized complex with calcium.

The unfulfilled promises of scorpion insectotoxins

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2015
Since the description and biochemical characterization of the first insect-specific neurotoxins from scorpion venoms, almost all contributions have highlighted their potential application as leads for the development of potent bioinsecticides.

Endangered Saudi Arabian plants having ethnobotanical evidence as antidotes for scorpion envenoming

open access: yesClinical Phytoscience, 2020
Scorpion sting envenoming in Saudi Arabia posed major public health problems. Conventional treatment with antivenom with its limitations and hazards called for the use of support remediation like prazosin therapy and phytotherapy as alternative solutions

Geographic Range Size Predicts Butterfly Species' Tolerance to Heavy Metals More Than Evolutionary History With Toxic Larval Diets

open access: yesEvolutionary Applications, Volume 18, Issue 5, May 2025.
ABSTRACT Some organisms appear to thrive in contaminated environments, while others are more sensitive, though the causes of this variation are unclear. The toxin coevolution hypothesis posits that an evolutionary history with natural toxins preadapts species to deal with novel toxins, while the range‐size‐tolerance hypothesis posits that a larger ...

Danger versus fear: A key to understanding biophobia

open access: yesPeople and Nature, Volume 7, Issue 4, Page 847-859, April 2025.
Abstract Which animals do people fear most, and why? Exploring animal fears in humans is crucial for understanding reactions in the face of danger, addressing both innate and learned determinants. Because of the central role they are thought to have played in primate evolution, most studies have focused on the fear of snakes.
