n-sodium acrylate-o-carboxymethyl chitosan [cmch-g-paa(na)] bound fe3o4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. cmch-g-paa (na) was obtained by grafting of sodium polyacrylate on o-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegradability properties. a...

background: omega-3 polyunsaturated fatty acids (pufa) have beneficial effects on both specific and non-specific inflammatory reactions. the aim of this study was to evaluate the effect of dietary supplementation with fish oil in migraine prevention. methods: a 12-week, randomized, single-blind clinical trial was conducted from october 2008 to june 2009. a total of 67 patients (52 women, 15 men...

dietary factors are suggested to be involved in recent increases in the prevalence of asthma. the differences in dietary intake of 23 asthmatic and 317 non-asthmatic students were investigated, who were chosen by multistage stratified cluster sampling. the dietary data were assessed by food frequency questionnaire and a 24-h recall form. total calorie and fat intake were similar. daily intake o...

background: electroconvulsive therapy (ect) is usually given to people with severe depression which has not responded to other forms of treatment such as anti-depressants. ect may be accompanied by potentially significant medical complications including prolonged seizures, prolonged apnea, or cardiac or pulmonary complications. modification of ect with brief anesthesia and muscle relaxants shou...

in a cross section of the patients scheduled for various operations, the plausability of lidocaine as an induction agent is studied and described. the results were dismaying suggesting, henceforth, that as an induction agent, lidocaine altogether fails to accomplish the assignment assigned to this drug.

the present work investigated the preparation of biodegradable beads with alginate polymer by ionotropic gelation method to improve the control release properties of the antibiotic rifampicin. ionotropic gelation method was applied to prepare beads using calcium chloride (cacl2) as cationic component and alginate as an anionic component. in this method, adding 0.5% w/v polyvinyl alcohol (pva) t...

abstract: warfarin is the most commonly used oral anticoagulant drug in clinical practice with extreme inter and intra-individual variation in pharmacokinetic properties. na valproate, a broad spectrum anticonvulsant agent, is best known for its enzyme inhibition properties and also displacement of protein binding sites. interaction between warfarin and psychotropic drugs including valproate ar...
