the present study evaluated the effect of packaging (air, vacuum) with or without addition of sodium acetate (2% w/v) on shelf-life extension of rainbow trout (oncorhynchus mykiss) under refrigeration, for a period of 18 days. four different treatments were tested: cap: control air pack; saap: sodium acetate treated aerobic packaging; vp: vacuum packaging in the absence of sodium acetate; and s...

preparation of tretinoin-containing microspheres with the aim of reducing undesirable skin reactions towards trans retinoic acid (tra) and thus, improving patient compliance is of particular interest. these microspheres have to be smaller than 30 m m to avoid causing gritty feel when applying on the skin, and slow the release of drug to minimize its skin side effects. following preliminary eval...

The effect of acetate ion introduced to aqueous solutions was investigated for the extraction/separation of Ni and Co from a dilute sulfate media. The separation of Co and Ni was improved by introducing acetate to aqueous media. By the use of the slope analysis method,the stoichiometric coefficient of the extractant was found to be 4 for cobalt and 3.5 or 4 for nickel depending on the aceta...

in order to increase the productivity of human interleukin-2 (il-2) as a model protein in the recombinant e.colibl21 (de3), the effect of magnesium acetate and manganese acetate was studied based on full factorial design experiments magnesium acetate and manganese acetate and their interaction exhibited an increasing effect on il-2 expression level upto 25.24%, 16.80% and 23.30%, respectively, ...

abstract wind erosion of soils and suspended particles in iran is one of the serious environmental and agricultural problems which affect agricultural lands, water reservoirs, irrigation canals, drains and etc. therefore wind erosion control needs attention specially in arid and semi-arid regions. although in recent years, some polymeric materials have been used for improvement of structural st...

background and aims . the aim of this study was to evaluate the clinical desensitizing effects of potassium nitrate and strontium acetate in reduction of hypersensitivity. materials and methods . thirty eight patients who presented dental hypersensitivity were selected and randomly allo-cated into two groups. group i: patients who were treated by potassium nitrate 5% foam, and group ii: patient...
