Objective:To establish a spatial geo-database for scorpions in Iran,and to identify the suitable ecological niches for the most dangerous scorpion species under different climate change ***:The spatial distribution of six poisonous scorpion species of Iran were modeled:Hemiscorpius lepturus,Androctonus crassicauda,Mesobuthus eupeus,Hottentotta saulcyi,Hottentotta zagrosensis,and Odontobuthus(O.)doriae,under RCP2.6 and RCP8.5 climate change *** Max Ent ecological niche model was used to predict climate suitability for these scorpion species in the 2030 s and 2050 s,and the data were compared with environmental suitability under the current bioclimatic ***:A total of 73 species and subspecies of scorpions belonging to 19 genera in Iran were *** Province has the highest species diversity with 34 species and *** most poisonous scorpion species of Iran are scattered in the semi-arid climates,at an altitudinal range between 11 m and 2954 m above sea *** is projected that ***,Androctonus crassicauda and Mesobuthus eupeus species would be widely distributed in most parts of the country,whereas the most suitable ecological niches for the other species would be limited to the west and/or southwestern part of ***:Although the environmental suitability for all the species would change under the two climate change scenarios,the change would be more significant for *** under RCP8.5 in the 2050 *** findings can be used as basis for future studies in the areas with the highest environmental suitability for the most dangerous scorpion species to fill the gaps in the ecology of scorpion species in these areas.

The Interesting of Antifungal Effects of Novel In Vitro Fabrics of Stabilized ZnO Nanofluids

Advances in Nanoparticles 2016年第4期5卷 206-223页

According to the extent of fungal infections, to be chronic these such diseases and recently the emerging issue of increased antibiotic resistance in fungal infections, most of scientists are going to find a proper way to replace antibacterial agent by significant semiconductor ZnO nanoparticles (NPs). They are well known to be one of the most important and special metal oxide nanoparticles in pharmaceutical against the most common fungi. ZnO nanoparticles were synthesized using sol-gel, hydrothermal and functionalized surface methods and formulated in water solutions as nanofluids. XRD, FTIR and SEM techniques and UV-Vis absorbance spectroscopy characterized their ZnO modified nanostructures. Also antimycotic potential according to generally tests such as: (MIC) minimum inhibitory concentration, (MFC) minimum fungicidal concentration and normally well diffusion method with standard strains fungi were performed. Among five common fungi strains using in this research, new various ZnO nanofluids showed noticeable results for dermatophyte fungi like Trichophyton mentagrophytes, Microsporum gypseum, Microsporum canis, Candida albicans and Candid tropicalis which had un growth zones in order 70, 40, 35, 30 and 30 mm in comparing with Clotrimazole reference reagent: 30, 25, 25, 18 and 20 mm by well method. The performance of MIC for ZnO nanofluids on fungi was determined to be equal to 0.35, 3.12, 6.25, 6.25 and 6.25 μgr/ml and MFC of nanoproducts showed the 1.5, 12.5, 25, 25 and 25 μgr/ml. Therefore, the designed ZnO nanofluids could reveal the most effect on fungi which cause dermal (ringworm), mucosal (thrush) and vaginal infections, so we are able to apply these surface high energetic ZnO water-based nanofluid formulations as in vitro nanomedicine and nanohygiene for the first time.
