the aim of this study was to investigate the rheological behavior and mucoadhesive nature of saliva substitutes, by incorporating various mucoadhesive polymers into an artificial saliva pump spray formulation. for this purpose various mucoadhesive polymers including cellulosic polymers in the range of 0.1-1.0% and carbomers such as c974p, c971, c934p and c971 in the range of 0.01-0.1% were adde...

Purposes: Propranolol HCl is a beta blocker commonly used worldwide; however, it shows a low bioavailability due to its extensive first-pass metabolism. To solve this problem, a novel drug delivery system such as buccoadhesive system might be helpful. The aim of the present investigation is to prepare the buccoadhesive tablet of propranolol HCl using different mucoadhesive polymers. Method: Buc...

Ludwig Wittgenstein said that almost all arguments were due to a failure to agree on the meanings of the terms being used. This certainly applies in the health service where discussions roam aimlessly over topics such as efficiency or equity or quality when it is quite obvious that all those involved are using a term with a different meaning. Where a term has a relatively sharply defined, techn...

Psychologists often speak about language and meaning in terms of individual "words" that label "things" in the world. Such expressions emerge not only in casual speech, but also pervade the scholarly literature. Influential works such as Roger Brown's (1958) Words and Things lend support to this tendency in their titles, if not always in their detailed argu ments. Speaking in this way perpetuat...

denotation is defined as being a sign of something, as smoke denotes fire. however, literal denotation is used where meaning of a word takes shape in the mind because of conception of the word. taking shape of meanings of words in man’s mind may be caused by such variety of causes as structure of the word, role of the word in a phrase, using a dictionary, circumstances of utterance of the word,...
