Introduction: Studies concerning the biology and ecology of scorpions in Iran are very limited , and these studies must be begun with identification of habitats and funa of scorpions of each region in the country and completed with biological and ecological charactristics .The aim of this study was to identify and determine the funa of Lorestan scorpions. Materials and Methods: In this descrip...

Scorpion primers can be used to detect PCR products in homogeneous solution. Their structure promotes a unimolecular probing mechanism. We compare their performance with that of the same probe sequence forced to act in a bimolecular manner. The data suggest that Scorpions indeed probe by a unimolecular mechanism which is faster and more efficient than the bimolecular mechanism. This mechanism i...

The phylogenetic position of scorpions within the Chelicerata has been the subject of much debate in recent years (e.g. Weygoldt & Paulus, 1979; Bergström, 1980; Van der Hammen, 1989; Shultz, 1990; Starobogatov, 1990), but it revolves around one primary question: are scorpions part of a monophyletic Arachnida, or are they “merostomes” which exhibit a terrestrial grade of existence? Inclusion of...

background: the mesobuthus eupeus scorpion venoms are known to contain α-toxin peptides, many of which interfere with k+ ion channel function. these toxin peptides have important value in  the pharmacology and physiology studies of specific k+ channel of cells. objectives: given the  lack of information of the molecular biology of peptides in the toxin of iranian scorpions, the aim of this stud...

Predators as diverse as snakes, scorpions, spiders, insects and snails manufacture venoms to incapacitate their prey. Most venoms contain a cocktail of neurotoxins and each neurotoxin is designed to target specific receptors in the nervous and muscular systems. Most neurotoxins act peripherally and interfere with the ability of the prey's nervous system to generate muscle contraction or relaxat...

Although Mesobuthus scorpions in China have become endangered in recent years, they are largely underinvestigated. Even the baseline data on their distributions are lacking. Here the geographical distributions of two Mesobuthus scorpions in China are provided through a combined study of systematic field surveys and GIS-based ecological niche modeling using 227 surveyed point occurrence data acr...

In this study, two Leiurus abdullahbayrami scorpion venoms were analyzed wif MALDI-TOFMS for teh first time and their peptide protein distributions compared. Teh total amount of was measured Nano Ready Touch device at a wavelength 280 prepared to be equal 2mg/mL concentration. Afterwards, supernatants separated by centrifugation +4 ºC 15 minutes 15,000 rpm, 250 µL matrix solution (18 mg/mL α-CH...

Scorpions are abundant in arid areas, where their population biomass may exceed that of vertebrates. Since scorpions are predators of small arthropods and feed infrequently across multi-year lifespans, a parsimonious explanation for their observed, anomalously high biomass may be a depressed metabolic rate (MR). We tested the hypothesis that scorpion MR is significantly depressed compared with ...

23 While it would appear that the decision to incorporate or subsume the Directorate of Special Operations (or Scorpions), into the South African Police Service (SAPS) is a fait accompli, the process of incorporation will not be straightforward. This is largely because the decision to disband the Scorpions is politically motivated, rather than motivated by practical concerns around the function...

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. Methods: In this analytic retrospective study, all medical charts of patients ...
