introduction: the optimum removal of bacteria and their toxins from periodontal pockets is not always obtained by conventional mechanical debridement. adjunctive therapies may improve tissue healing through detoxification and bactericidal effects. the purpose of the present study was to evaluate the impact of adjunctive laser therapy (lt) and photodynamic therapy (pdt) on patients with chronic ...

during last two decades, polysaccharides such as alginate (alg) alone and in combination with other biopolymers are widely used in vaccine and drug delivery systems. the aim of the present work was to investigate the potential utility of microparticles made of alginate (alg) as new vehicles for improving nasal vaccine delivery. for this purpose, diphtheria toxoid (dt) was chosen as a model anti...

a method for the controllable synthesis of silver nanoparticles based on a complexing agent method was developed. citric acid was used as a complexing agent. the effect of ph (1.6 to 5.17) on the size and net height (as obtained from xrd analyses) of silver nanoparticles was investigated. the nanoparticles (10 to 40 nm) were characterized using xrd, tem, sem, edx, uv-vis spectroscopy and tg/dtg...

pulling force is one of the most important variables in pultrusion process which determines the capacity of the pultrusion machine. one of the characteristics of a desired pultrusion process is a low pulling force and a high line speed.among the important factors affecting the pulling force are the internal mold release agent (imr) and the content and particle size of the filler in resin formul...

introduction: the antibacterial effects of calcium hydroxide (ch), mineral trioxide aggregate (mta), and calcium enriched mixture (cem) cement against various spp. of microorganisms were assessed in-vitro using agar diffusion test. materials and methods: a base layer of petri plates was made using muller-hinton agar. four cavities were made in agar and filled with freshly mixed materials after ...
