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% ...

In this study, thermal simulation experiments under different austenitization temperatures and different stress states were conducted. High-temperature laser scanning confocal microscopy (LSCM), thermal dilatometry, and scanning electron microscope (SEM) were used to quantitatively investigate the effects of the uniaxial compressive stress on bainitic transformation at 330 ̋C following differen...

It is often anticipated that two-photon excitation (TPE) laser scanning microscopy should improve cell survival and tissue penetration relative to conventional one-photon excitation (OPE) confocal scanning laser microscopy (CLSM). However few studies have directly compared live cell imaging using one- vs two-photon laser scanning microscopy. We have used calcein-loaded in situ chondrocytes with...

Current musculoskeletal imaging techniques usually target the macro-morphology of articular cartilage or use histological analysis. These techniques are able to reveal advanced osteoarthritic changes in articular cartilage but fail to give detailed information to distinguish early osteoarthritis from healthy cartilage, and this necessitates high-resolution imaging techniques measuring cells and...

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...

In recent years, image-scanning microscopy (ISM, also termed pixel-reassignment microscopy) has emerged as a technique that improves the resolution and signal-to-noise compared to confocal widefield by employing detector array at image plane of laser scanning microscope. Here, we present k-space analysis coherent ISM, showing ISM is equivalent spotlight synthetic-aperture radar (SAR) analogous ...
