background: anti-microbial agents have been used as a chemotherapeutic agent to improve oral health. this in vitro study was carried out to determine antimicrobial efficacy of different toothpastes and mouthrinses against the oral pathogens.     methods: a total of five toothpastes and five mouthrinses were tested for their antimicrobial activity against three oral pathogens namely, streptococc...

mucoadhesive polymers that bind to the gastric mucin or epithelial cell surface are useful in drug delivery for the purpose of increasing the intimacy and duration of contact of drug with the absorbing membrane. several synthetic polymers are in use for this purpose. since the biodegradability of the synthetic polymers are questionable, in this investigation, an oral mucoadhesive controlled del...

organophosphorus compounds are highly toxic chemicals that have application in production of warfare agents and agricultural pesticides. detoxification of areas that have been exposed to these types of materials is of vital importance and several approaches have been used for this purpose. biodegradation of organophosphates is one of these approaches that is in the center of attention due to it...

long protocol of gonadotropin-releasing hormone-analougue (gnrh-a) can result in the formation of ovarian cyst by the transient initial stimulatory effect which increases the levels of both follicle-stimulating hormone (fsh) and luteinizing hormone (lh). these cysts require surgical drainage or result in poor ovarian response. ovarian cyst formation can be prevented by taking oral contraceptive...

chemotherapy research highly prioritizes overcoming the multidrug resistance (mdr) in human tumors. liposomal formulation of fluoxetine, as a fourth generation chemosensitizer, was constructed and characterized for percent entrapment, release profile, morphology, particle size, zeta potential and stability. liposomes were prepared using different active loading techniques. the influence of diff...

the ever severe dynamic competitive environment has led to increasing complexity of strategic decision making in giant organizations. strategy formulation is one of basic processes in achieving long range goals. since, in ordinary methods considering all factors and their significance in accomplishing individual goals are almost impossible. here, a new approach based on clustering method is pro...
