The difference between serum and plasma potassium concentrations is well known, but we believe the clinical significance of the intra-and interindividual variability of the difference is not fully appreciated. This variability differs between types of blood collection tubes, possibly because of the extent of clot retraction induced by the surface of the tube or the clotting accelerator. Even fo...

statement of problem: bioglasses are a series of biocompatible dental materials, which are considered as light conducting inserts in resin composite restorations. consequently, their chemical stability is more essential when they are used in conjunction with resin composite. objectives: the aim of this study was to evaluate and compare the chemical stability of bioglass with dental porcelain an...

The pharmacokinetic (PK) and pharmacodynamic (PD) profile of an antimicrobial agent provides important information that can be used to maximize bacteriologic and clinical efficacy, minimize selective pressure for the development of antimicrobial resistance, and determine an optimal dosing regimen. Judicious selection of an antimicrobial based on local susceptibility data and PK and PD parameter...

Gastrointestinal symptoms (discomfort, mucosal lesions and sometimes ulceration) have been seen in healthy subjects taking some forms of potassium supplements (e.g. slow-release, wax matrix formulations) with doses ranging from about 1 to 5 g potassium per day, or more, but incidence and severity seem to be more dependent on the formulation than on dose. In healthy adults administration of sing...
