The electrochemical oxidation of repaglinide has been carried out in Britton-Robinson buffer at carbon paste and glassy carbon electrodes. Repaglinide exhibits a well-defined irreversible oxidation peak over the entire pH range (2-11). Differential pulse voltammetry was used to determine repaglinide in pure form. The peak current varied linearly in the following ranges: 8.0 x 10(-7)-3.2 x 10(-6...

This article is focused on the determination of lidocaine hydrochloride as a local anaesthetic drug. A potentiometric method based on modified screen-printed and modified carbon paste ion-selective electrodes was described for the determination of lidocaine hydrochloride in different pharmaceutical preparations and biological fluids (urine and serum). It was based on potentiometric titration of...

In the design of biomaterials for therapeutic application the evaluation of cellular/tissue responses play a key role. In this study, the in vivo bone-regenerative capacity and resorption of granular BONITmatrix and a paste-like bone substitution material on the basis of BONITmatrix were investigated in a rat cranial defect model. The results obtained with both biomaterials were compared to eac...

The efficacy of an oral formulation of ivermectin plus praziquantel in the reduction of nematode and cestode egg counts in horses was assessed in 273 horses under field conditions at 15 sites in North America (n = 6) and Europe (n = 9). Horses were confirmed by fecal examination to have natural infections of strongyles (100%) and tapeworms (76%). Replicates of four horses were formed at each si...

BACKGROUND This study compared the effectiveness of a Specially Designed Paste Carrier technique with the Syringe-Spreader technique and the Syringe-Lentulo spiral technique in the intracanal placement of calcium hydroxide. METHODS Three groups, each containing 15 single-rooted human anterior teeth were prepared using standardized Mtwo rotary instruments to a master apical file size 40 with 0...

OBJECTIVES This study was aimed to investigate effects of 2% minocycline-HCl paste root conditioning on periodontal surgery. MATERIALS AND METHODS In vitro, cementum slices affected by periodontitis were randomly conditioned with 2% minocycline-HCl paste, 2% minocycline-HCl liquid, and 0.9% saline. NIH3T3 cells were cultured and attached to the each slide, and the viability and proliferation ...

AIM The aim of these case reports is to present a treatment to promote root-end growth and apexification in nonvital immature permanent teeth in children. METHODS AND MATERIALS Three cases were presented where the calcium hydroxide and iodoform paste Metapex® was placed in the root canals of immature permanent teeth using disposable plastic tips. The teeth involved were evaluated radiographic...

When programmers develop and evolve software, they frequently copy and paste (C&P) code from an existing code base, or sources such as web pages or documentation. We believe that programmers follow a small number of well defined C&P usage patterns when they program, and understanding these patterns would enable us to design tools to improve the quality of software. We conducted an ethnographic ...
