The sample may serve as weaning protein source and contained 52.91% protein. This species is unfortunately often found near human habitations (in cracks in walls etc. a large percentage of the species have venom which is highly toxic to humans. The Androctonus mauretanicus mauretanicus venom is one of the most toxic Buthidae venoms ever described (its median lethal dose ranges from 0.05 to 0.2 mg/kg by subcutaneous injection in mice) and immunotherapy remains the treatment of choice [ 17 ]. Scorpion venom contains various biomolecules with potential therapeutic values against different diseases, including cancer. The peptide consists of 37 amino acid residues, which include six cysteines. This species are medical important, and cause several deaths each year. The present work describes a novel Kv3.1 inhibitor peptide isolated from Androctonus australis hectorvenom. 22 The sLD of Tityus obscurus and Tityus serrulatus scorpions revealed a lesser lethal potential (3.13 and 0.99 mg/kg body weight, respectively) compared to Am and Bo venoms, 24 same for Mesobuthus eupeus venom . Androctonus australis hector (Aah) venom induces high plasma concentrations of proinflammatory cytokines including interleukin 1 beta (IL-1b), interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-a) [4], and sympathetic tone is activated by experimental envenomation [5]. Androctonus australis is a fat-tailed desert scorpion distributed over North Africa and the Middle East. It is used in Algeria to treat many diseases.

The venom of the scorpion Androctonus australis hector contains several protein neurotoxins of which structure and structure/activity relationships have been extensively studied. This toxin is a weak beta toxin because it has no effect on Nav1.2a/SCN2A voltage-dependent sodium channels when perfused at a concentration of 100 nM, but when added to the extracellular bath solution at a concentration of 1 M it shifts the voltage of activation . Rochat H, Kopeyan C, Miranda F, Lissitzky S . The present study was designed to determine the evidence of neurokinin 1 (NK1) receptor and the involvement of mast cell activation to induce pulmonary edema and to increase vascular permeability after Androctonus australis hector (Aah) venom administration. To this end, mast cells were depleted using compound 48/80 (C48/80). Typical manifestations of Aah scorpion envenomation are cardiac dysfunction, systemic inflammatory response syndrome, pulmonary edema and respiratory failure [20]. b MPO activity. Several decades of exploration have led to a comprehensive inventory of their venom components at chemical, pharmacological, and immunological levels.

Methods The cytotoxic and antiproliferative activities were estimated using MTT assay, lactate dehydrogenase release and clonogenic assays. Couldn't find anything else on other species, but maybe someone with more experience in the field can find out more about that! Scorpion venoms contain toxins that act on ion channels of excitable cells and that are likely responsible for noxious effects when people are stung [[]].The venom of the North African scorpion Androctonus australis hector contains several potent neurotoxins that act on potential-dependent sodium . On the hobby's 1 - 5 rating system, this roughly represents level 3. Envenoming by Androctonus australis hector (Aah) scorpion is characterized by various symptoms, including pain and cardiovascular and respiratory disturbances.

AaH-II was originally discovered from the venom of the scorpion Androctonus australis Hector and belongs to alpha-toxins. With a bite of androctonus, only a weak injection is felt, but its venom contains strong neurotoxins that have a toxic effect on the heart and central nervous system. They are all on the venomous side, but not to the extreme of Androctonus. (g/ml) HCV Inhibition (%) 0 20 40 60 80 100 Chemistry. Venom Androctonus Australis: in vitro and in vivo study Mohamed S.

The protein sequence data will appear in the UniProt Knowledgebase under the accession number C0HLZ5. Data Availability Statement. Toxins from scorpion venom are responsible for severe metabolic and tissue disruption and immunotherapy is the only specific treatment able to neutralize the toxic effects of scorpion venom. Introduction: The physiopathology of scorpion envenoming is very complex, and can induce several perturbations reaching different systems, including nervous, cardiovascular, immune and respiratory systems. The toxicity of the Aah scorpion venom is essentially due to the presence of three small basic toxins (7 kDa) that act on the voltage-gated sodium channels of excitable cells. In the current study, we identified one Nanobody (Nb), a single-domain antigen-binding fragment of a dromedary Heavy-chain antibody (HCAb) that recognizes specifically the Androctonus australis hector AahI' toxin. In the present study, we focused on the biochemical and pharmacological characterization of the component in AahG50 scorpion venom that potently and selectively blocks the Kv3.1 channels. In vitro, the human breast cancer MCF-7 cell line was treated with . cDNAs encoding precursors of Androctonus australis neuro- toxins. A novel type of venom peptide with six disulfide bridges, referred to as Androcin, was identified from the scorpion Androctonus bicolor using a cDNA library strategy. This toxin is active only on insects (By similarity). Laraba-Djebari F, Hammoudi-Triki D. Use of toxic fraction isolated from Algerian Androctonus australis hector scorpion venom for the assessment of anti-venom serum.

Several studies report that the sympathetic Androctonus australis A.AU3 KJ538462.1 Egypt The venom of this scorpion species living in North Africa has been extensively studied. The Am venom showed an almost similar toxicity to that of the Androctonus australis hector venom (335 g/kg body weight) via IP route. Recently, it was established that venom toxins from scorpions induced cytotoxic, antiproliferative and apoptogenic effects on cancer cells. This was comparable to the level previously . A comparison of the electrical and pharmacological properties of muscle and nerve fibres from Androctonus australis with those from the crayfish Procambarus clarkii enabled us to understand the lack of effect of scorpion venom (110-180 microg ml-1) and purified . Venom: This is one of the worldst most dangerous scorpion, with a very potent venom. In order to optimize and develop new therapeutic strategies for scorpion envenoming, a phytotherapeutic approach has been investigated. Androctonusaustralisisprimarilyinvolvedinenvenomations inNorthAfrica,notablyinTunisiaandAlgeria,andconstitutes asignificantpublichealthprobleminthisregion.Thetoxicityof the venom is mainly due to various neurotoxins that belong to two distinct structural and immunological groups, group I (the AahI andAahIII toxins) and group II (AahII). It is one of the largest scorpions in the world and lives for 6-8 years. It contains 37 amino acid residues, has a molecular mass of 3850 Da, is closely packed by three disulfide bridges and a blocked N-terminal amino acid.

In Algeria, Aah is responsible for approximately 50,000 cases of scorpion envenomation per year. In animal experiments, the venom of A. australis displayed lower toxicity than that of L. quinquestriatus, but the amounts of venom available in this large species are correspondingly larger. The first member of the -KTx 15 subfamily characterized was Aa1 from the Androctonus australis venom (3869 Da) .
