Background: Scorpionism is a public health problem in some provinces in Iran. The present study aimed to assess the clinical manifestations of scorpion envenomation in Shiraz and determine a clinical severity grading for Iranian scorpion envenomation in order to suggest a treatment guideline for emergency physicians.

Fluorophores from the hemolymph of yellow sac spiders (Cheiracanthium mildei) have been characterized using excitation emission matrix (EEM) fluorescence spectroscopy. This approach provides characterization of fluorophores present in the organism without having to isolate pure samples. Minimal variation occurs between individual samples and each EEM has two distinct peaks, suggesting two fluor...

Introduction: Scorpion bite is one of the major health problems in most countries. Lordegan is one of the areas where several reports of Scorpion bite occur. The purpose of this study was to describe the epidemiological and demographic characteristics of selected scorpions for preventive measures. Methods: This descriptive cross-sectional study was conducted to collect information about all th...

Scorpion envenomation is a public health problem in tropical and subtropical countries. The majority of scorpion sting cases present with local pain at the site of sting and follow a benign clinical course. Severe intoxication may include cardiac and respiratory dysfunc-tion, leading to multi-system organ failure and death (1, 2). The deaths in scorpion sting envenomation (SE) are attributed to...

Objective: Scorpion stings are common in tropical regions of Iran. Hemiscorpius enischnochela are distributed in southern part of Iran. The venom of this scorpion causes severe hemolysis, hemoglobinuria, and occasionally death.Case Presentation: This report describes the clinical manifestations of envenomation by H. enischnochela in a 3-year-old boy from Ruydar city in south of Iran.<br /...

Scorpions (order Scorpiones) are unusual among arthropods, both for the extreme heteronomy of their bauplan and for the high gene family turnover exhibited in their genomes. These phenomena appear to be correlated, as two scorpion species have been shown to possess nearly twice the number of Hox genes present in most arthropods. Segmentally offset anterior expression boundaries of a subset of H...

Scorpions are among the oldest terrestrial arthropods and they have passed through small morphological changes during their evolutionary history on land. They are efficient predators capable of capturing and consuming large preys and due to envenomation these animals can become a human health challenge. Understanding the physiology of scorpions can not only lead to evolutionary insights but als...

Temperature can profoundly affect many physiological processes, including muscle performance. Many ectotherms appear sensitive to this relationship, choosing times and locations of activity permitting high body temperatures and, thus, quick escape from predators. High body temperatures, however, can lead to dehydration, which in turn affects muscle performance. Striped bark scorpions Centruroid...
