in this study, the trace amounts of erythrosine, as a food dye is determined by cloud point extraction-scanometry (cpe-scanometry) as a new, facile, available, fast, sensitive, and low cost method. the method is based on the cpe of analyte from aqueous solution, diluting the extracted surfactant-rich phase with ethanol, transfer to plexiglas®cell and scanning the cells containing the analyte so...

lithium is widely used in medicine as an anti-depressive drug. in spite of abundant literature, questions on the side effects of lithium ions are far from being answered. in this study, the effects of lithium on biochemical parameters related to lipid metabolism were investigated. male wistar rats were treated with different doses of lithium for a period of up to 60 days. blood samples were col...

co2+ & er3+ co-doped zno nanocrystals were synthesized by the hydrothermal method at 180°c and ph= 12 for 48 h. powder xrd patterns indicate that the zn1-2xerxcoxo crystals (0.00

background: vancomycin is used abundantly in patients undergoing hsct, especially during neutropenic fever. despite its widespread use little is known about vancomycin pharmacokinetics in hsct patients. we conducted this study to investigate vancomycin pharmacokinetic parameters in our hsct patients and to evaluate current dosing regimen based on trough vancomycin concentrations measurement. me...

the aim of the present study was to estimate the genetic parameters and genetic trends of somatic cell score (scs) in the first 3 lactations of iranian holstein cows by random regression (rr) animal model by using restricted maximum likelihood (reml) method. the data set used in this analysis included observations of 340318 test-day records of 41526 cows in 288 herds; 89969 test-day of 11750 co...

an essential requirement for an operating pem fuel cell is providing proper water content in the membrane. to avoid water flooding an appropriate water balance is required. here, an analytic model of a planar membrane humidifier for pem fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. a n...
