We describe the female and male of the Neotropical fungus-growing ant Mycerarotes carinatus, hitherto only known from type locality, Rio de Janeiro state, Brazil, based on samples of workers. The sexual forms were obtained from a nest maintained in the laboratory. The samples found in Minas Gerais state, expand the geographic distribution of the species. We illustrate the external architecture ...
چکید ه سابقه و هدف زهر مار جعفری ( Echis carinatus ) مخلوط پیچیده‌ای از مواد سمی است . این زهر شامل متالوپروتئازهایی است، که فعال‌کننده قوی پروترومبین هستند. این ترکیبات بر سیستم انعقاد خون اثر دارند و باعث ایجاد لخته خون می‌شوند. در این مطالعه، مکانیسم اثر سم مار جعفری ایرانی روی پروتئین‌های پلاسمای انسان (پروترومبین یا فیبرینوژن) و اثر انعقادی آن مورد بررسی قرار گرفت. هدف از این مطالعه،...
The antibacterial activities of eight snake crude venom (Macrovipera lebetina obtusa, Pseudocerastes persicus, Pseudocerastes urarachnoides, Echis carinatus sochureki, Gloydius halys caucasicus, Naja (naja) oxiana, and two species of true sea snakes Enhydrina schistose and Hydrophis cyanocinctus) were assessed against five important standard pathogenic bacterial strains (Escherichia coli, ...

Background: Venom variation occurs at all taxonomical levels and can impact significantly upon the clinical manifestations and efficacy of antivenom therapy following snakebite. Variation in snake venom composition is thought to be subject to strong natural selection as a result of adaptation towards specific diets. Members of the medically important genus Echis exhibit considerable variation i...
Viperbite is often associated with severe local toxicity, including progressive hemorrhage and myotoxicity, persistent even after the administration of anti-snake venom (ASV). In the recent past, investigations have revealed the orchestrated actions of Zn2+ metalloproteases (Zn2+MPs), phospholipase A2s (PLA2s) and hyaluronidases (HYs) in the onset and progression of local toxicity from the bitt...
BACKGROUND AND OBJECTIVES We evaluated a new test, based on prothrombin activation by Echis Carinatus snake venom in the absence/presence of unfractionated heparin, in patients with venous thromboembolism (VTE). DESIGN AND METHODS The test (activated prothrombin heparin-inhibition test) was performed in 555 unselected, unrelated patients who had suffered from at least one objectively confirme...
In recent years, use of biodegradable polymers based nanoparticles has received highinterest in the development of vaccines delivery vehicles. The aim of study was to preparechitosan nanoparticles (CS NPs) for loading Echis carinatus (EC) venom and evaluate theirpotential as an adjuvant and antigen delivery system on a pilot scale. CS NPs were preparedusing ionic gelation method, and their char...
