three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (wssv) and transcription of antioxidant enzyme genes in pacific white shrimp litopenaeus vannamei. each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...

objective: sleep complaints are common among iranian chemically-injured veterans. the growing body of research has investigated (in) equalities between such subjective complaints and objective sleep records. moreover, sleep complaints are associated with depressive symptoms. depressive symptoms, also, have been frequently reported in chemically-injured veterans. therefore, the purpose of this p...

there are 3700 wells in tehran city, of which 850 are deep wells. to determine tehran ground water quality, as a pretest we selected 102 wells by simple random sampling; water analyses were made according to the latest edition (1985) of the standard methods. comparisons of the obtained results with who standards show that only 0.98% of the samples go beyond the maximum desirable concentration o...

the research focused to evaluate physical, chemical, and sensory properties of raw, blanched, and 2, 4, and 6% osmotically salt treated mandarin (citrus reticulata) peel powder. the yields of mandarin peel powder (mpp) were found in the range of 29.1 to 30.4% (db) for different treatments, which were not significantly different. the bulk density and solubility were found in the range of 1,267-1...

Water quality directly influences individual and public health. Monitoring of water supplies and their sanitation is of paramount importance.
