deproteinisation with acetonitrile (along with methanol or other reagents) is a useful and rapid technique in analysis of drugs or their metabolites in human serum. in this paper application of this simple technique in biopharmaceutical analysis using capillary electrophoresis (ce) is evaluated. some drugs with different ionic and protein binding properties were selected and dissolved in human ...

AIMS To investigate the prognostic significance of macular capillary drop-out and previous panretinal laser photocoagulation in diabetic macular oedema treated with intravitreal ranibizumab. METHODS Retrospective observational case series. Treatment-naive patients with diabetic macular oedema that had been treated with intravitreal ranibizumab as per the RESTORE study protocol for at least 12...

The amplified fragment-length polymorphism (AFLP) technology is a recently introduced method to investigate genomes of different complexity, from microbial to higher organisms. It is applied to purposes as diverse as identification of species, strain and varieties, investigation of genetic diversity within and between populations, simple and complex trait mapping, and construction of linkage an...

Background A decline in executive function could have a negative influence on the control of actions in dynamic situations, such as sports activities. Mouth rinsing with a carbohydrate solution could serve as an effective treatment for preserving the executive function in exercise. The purpose of this study was to examine the effects of mouth rinsing with a carbohydrate solution on executive fu...

AIM Jack Pro Spülung Plus (also available as "rheodol-Spülung plus") is recommended to mechanically maintain oral hygiene as part of an overall oral hygiene concept. Because Jack Pro Spülung Plus contains the active agents polihexanide and tosylchloramide sodium in concentrations below microbicidal efficacy, this study tested the hypothesis that the combination of mechanical rinsing and bacteri...

AIM This was to compare the salivary fluoride levels following tooth brushing with amine fluoride toothpastes containing three different concentrations of F (250 ppm F, 500 ppm F and 1250 ppm F) and to evaluate the effect of rinsing with water on the oral fluoride levels up to 90 min. METHODS A double blind randomised six-arm crossover study was conducted with 32 child participants. Patients ...

BACKGROUND Inhaled corticosteroids have dose related systemic effects determined by oral (swallowed or oropharyngeal absorption) and lung bioavailability. A study was undertaken to evaluate the significance of oropharyngeal absorption for fluticasone propionate. METHODS Sixteen healthy volunteers of mean age 29.3 years were studied using an open randomised, placebo controlled, four way crosso...

Background: Stevia is a natural, non-caloric sweetener with antimicrobial, antioxidant and anti-cariogenic properties. Aim was to assess compare the effect of 4.7% stevia solution, sucrose solution distilled water mouth rinsing on salivary pH. Methods: Randomized controlled trial latin square design followed involving 15 female participants aged 20-23 years. Participants were randomly allocated...
