OBJECTIVE To assess the effectiveness of weekly and daily schemes of preventive supplementation with supplementary iron to prevent iron deficiency anemia in non-anemic infants. METHODS A prospective population study with a quantitative approach and preventive intervention was performed in the city of Viçosa, Southeastern Brazil, in 2007-8. A total of 103 non-anemic children, aged between six ...

In this paper, the wet modification method is compared with grafting to modify nano-barium sulfate. The effects of method, time, modifier dosage, temperature, and other factors on degree activation modified sulfate are investigated solve agglomeration problems make it a suitable process for industrial production. Thermogravimetric analysis, infrared spectroscopy, scanning electron microscopy us...

polybrominated diphenyl ethers (pbdes) have been widely used in many products as flameretardants, which resulted in their release into the environment. little is known about the impact of coexisting pbdes on organisms. in this study, the in vivo effects of bde-47 and bde-99 on a suite of biomarkers, acetyl cholinesterase (ache), ethoxyresorufin-o-deethylase (erod), glutathione-s-transferase (gs...

Studies pertaining to drug-DNA interactions in treating a disease efficiently have taken an important place in recent times. Murthy and colleagues were active in correlating the drug activity, with physical parameters like refractivity, susceptibility, molecular electron ionization cross-section and the dosage. The molecular polarizability, diamagnetic susceptibility and molecular electron ioni...

We agree with Dr Weinberger that ideally the starting dosage of theophylline should be small, blood levels checked, and dosage built up. However, many of our patients live some distance from the hospital and we feel that it would be impracticable to recall these children frequently to measure levels and adjust dosage. We prefer to titrate our patients by starting with a high dosage, checking le...
