The confocal microscope, based on the principle of confocal imaging, is a recently introduced and invaluable tool for high-resolution fluorescence microscopy. It has gained popularity in the scientific and industrial communities since its inception. Although the application of confocal microscopes in dentistry started as early as 1994, the practical usage of this device in our country is just g...

background  to report normal variations of the limbal structures using in vivo laser scanning confocal microscopy. methods: this was a retrospective study of fourteen eyes from 11 healthy individuals. confocal imaging of cornea and limbus was performed using heidelberg retina tomograph iii rostock corneal module. results: the typical structure of the palisades of vogt (pov) was detected in 57% ...

background: the aim of this study was to evaluate and compare the in vitro biofi lm forming capacity of enterococcus faecalis on gutta-percha points disinfected with four disinfectants. materials and methods: a total of 50 gutta-percha points used in this study were divided into four test groups based on disinfectant (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, 20% neem, 13% benzalko...

Abstract Raman spectroscopy combined with confocal imaging, i.e. microscopy (CRM) is a relatively new technique huge potential for high-resolution chemical mapping of phase composition and spatial distribution in cement-based materials. However, the effects sample preparation various operating parameters on quality has not been systematically studied. This paper optimises CRM spectral carbonate...

The local authority Social Services Departments are going to get a bad press during the next year or two This seems quite certain, because of the attitudes and activities of certain Members of Parliament. There appears to be quite a vogue nowadays for Members to open debates, ask questions and make speeches not so much for their impact on the floor of the House as for the amount of press covera...

the relationship between qt dispersion and myocardial ischemia is still controversial. therefore, we aimed to investigate the relationship between qtd and the severity and extent of myocardial ischemia. in this cross-sectional study, 141 patients having symptoms of cad who referred to our medical center during 2009-2010, and were examined with myocardial isotope scan and ecg, were enrolled. bas...

reverse redistribution pattern is defined as decreased activity in the myocardium in the rest phase of the myocardial perfusion scan in comparison with the stress images. there are many studies concerning the etiology and clinical significant of this phenomenon in nuclear medicine literature. the dominant idea about etiology of reverse redistribution is early wash out of the radiotracer from th...
