objective(s) the aim of this study was to investigate the possibility of production of ibuprofen pellets with high amount of rate retarding polymer by aid of peg400 as plasticizer. materials and methods polyethylene glycol (peg400) in concentrations of 1, 3 or 5% w/w with respect to eudragit rl was used in production of pellets containing 60% ibuprofen and 40% excipient (2% polyvinylpyrrolidone...

We have previously reported that the addition of para-phenylenediamine (PPD) to the glycerol used for mounting preparations stained for immunofluorescence with FITC conjugates results in a marked retardation of the fading that occurs during fluorescence microscopy. Studies of the kinetics of this photo-bleaching performed by microfluorimetry and on FITC conjugate in solution and the effects of ...

A previous article in this journal (Coelen and Sullivan, 1981) reported new evidence that many State hospital prospective reimbursement (PR) programs have been successful in reducing hospital cost inflation. Limiting proliferation of redundant technologies and community services may be one method of reducing this cost inflation. Data compiled from a sample of over 2,500 hospitals in 15 rate-set...

The State of Florida has a draft radon standard for new construction. This study was conducted to evaluate the effectiveness of two slab types (monolithic and slab-in-stem wall) in retarding radon entry in new houses built in accordance with the proposed standard over high radon potential soils. Fourteen houses were monitored during their construction on sites whose soil gas radon concentration...
