background and objectives: anaplasma phagocytophilum is a zoonotic, tick borne rickettsial pathogen. a. phagocytophilum has been detected in north america, europe, africa and asia by molecular methods. in iran we have little information about the distribution of this agent in human and animals. materials and methods: from march 2007 to july 2007, one hundred and fifty blood samples and correspo...

background: anaplasmosis belongs to the complex of several tick-borne diseases and can cause diseases in the livestock with high economical losses. cattle that recover from acute infection become carriers and the parasite can persist most probably for the lifetime in the blood. the aim of the present study was the determination of the persistently infected cattle in a region of iran with the pr...

liposomes have attracted great interest as efficient carriers for nutrients, drugs and other bioactive agents as well as ideal models for biological membranes. this article intends to provide an overview of liposomes and nanoliposomes definition as well as their properties and preparation methods. also it elaborates on various applications of nanoliposomes in nanotherapy including diagnostics, ...

the aim of present study was to prepare gelatin nanoparticle for drug and gene delivery applications. these nanoparticles were prepared by two-step desolvation method. the body distribution of colloidal drug delivery systems was mainly influenced by two physicochemical properties namely particle size and surface characteristics. the influence of several factors on the fabrication process includ...

germanium nanowires (genws) were synthesized using chemical vapor deposition (cvd) based on vapor–liquid–solid (vls) mechanism with au nanoparticles as catalyst and germanium tetrachloride (gecl4) as a precursor of germanium. au catalysts were deposited on silicon wafer as a thin film, firstly by sputtering technique and secondly by submerging the silicon substrates in au colloidal solution, wh...

this paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. with regard the increasing importance of lng carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...
