This study was conducted to investigate the blood serum and diet levels of copper, zinc and iron in Holstein dairy cattle kept under industrial farming in Isfahan province, Iran. A total of 240 blood serum samples and 24 diet samples were collected from industrial dairy cattle farms. The Cu, Fe and Zn contents were assessed in samples using atomic absorption spectrophotometer. In serum samples,...
Background: BIV is a well-known bovine immunosuppressive cause, but its pathogenesis has not been well characterized. In recent years, it has been hypothesized that infection with BIV might predispose cattle to be infected by other agents. OBJECTIVE: This study was performed to investigate of BIV and Brucella co-infection so that in the future more studies will be done on the issue of predispos...
A fast and simple modified QuEChERS extraction method was developed for determination of Benzo[a]pyrene (BaP) in 137 traditional (Sangak), semi-industrial (Sangak) and industrial bread samples using spiked calibration curves by GC/MS. Sample preparation includes extraction of BaP into acetone followed by cleanup with dispersive solid phase extraction. The limit of detection and limit of quantif...

Background and Objectives: Changes in lifestyles and food patterns and consumption of ready-to-eat and fried foods have increased probability of chronic non-communicable diseases (NCDs). Studies have illustrated associations between salt, total fat, saturated fatty acid and trans fatty acid contents of the industrial and guild fried products in Iran. Materials & Methods: In this study, 69 sam...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
