Micro ‐computed tomographic assessment of quality of obturation in the apical third with continuous wave vertical compaction and single match taper sized cone obturation techniques
Summary
The aim of the present micro‐computed tomography (Micro‐CT) analysis was to compare the quality of obturation in the apical third of the root with the warm vertical compaction (WVC) and single matching taper sized cone (SMTSC) techniques. Mesial roots of 16 freshly extracted mandibular first molar teeth (with a total of 32 canals) were used. Canals in each mesial root were shaped to a size F3 Protaper and were randomly assigned to either continuous wave vertical compaction or single match tapered size cone technique. Volume of voids and gaps in the obturated roots were measured using micro‐CT scanning at 1, 3...

Apigenin induced apoptosis in esophageal carcinoma cells by destruction membrane structures
Summary
Apigenin has shown to have killing effects on some kinds of solid tumor cells. However, the changes in cell membrane induced by apigenin on subcellular‐ or nanometer‐level were still unclear. In this work, human esophageal cancer cells (EC9706 and KYSE150 cells) were employed as cell model to detect the cytotoxicity of apigenin, including cell growth inhibition, apoptosis induction, membrane toxicity, etc. MTT assay showed that apigenin could remarkably inhibit the growth and proliferation in both types of cells. Annexin V/PI‐based flow cytometry analysis showed that the cytotoxic effects of apigenin in KYSE1...

Optical and surface properties of optically transparent Li3PO4 solid electrolyte layer for transparent solid batteries
In this study, optical and surface properties of the optically transparent Li3PO4 solid electrolyte layer for transparent solid battery have been investigated for the first time. To determine the optical properties, transmittance, absorbance, reflection, refractive index spectra, and optical band gap were determined by UV‐Vis spectrophotometer and optical interferometer. The surface property of the transparent Li3PO4 solid electrolyte was analyzed using atomic force microscopy. One another important parameter is contact angle (CA) surface free energy (SFE). CA and SFE were determined by optical tensiometer. These values ...

Effect of self‐assembling peptide P11‐4 on enamel erosion: AFM and SEM studies
Summary
The aim of the present in vitro study was to evaluate the protective effect of self‐assembling peptide P11‐4 (Curodont™ Protect/Credentis) on enamel erosion produced by a soft‐drink, by using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). Thirty human incisors were equally and randomly assigned to 6 groups. Group 1: intact enamel, group 2: soft drink, group 3: Curodont™ Protect applied, group 4: Curodont™ Protect applied + soft drink, group 5: soft drink + Curodont™ Protect applied, group 6: soft drink + Curodont™ Protect applied + soft drink. Specimens were ob...

Imaging normal and cancerous human gastric muscular layer in transverse and longitudinal sections by multiphoton microscopy
Summary
Multiphoton microscopy (MPM) based on two‐photon excited fluorescence (TPEF) and second harmonic generation (SHG) has been widely used for imaging microstructure of biological tissues. In this article, we used MPM to investigate the microstructure changes of normal and cancerous human gastric muscular layer in transverse and longitudinal sections. The results displayed different patterns of microstructure changes of smooth muscular tissue, cell morphology and interstitial fibers in transverse and longitudinal sections, being similar to standard histopathological images but without the need for tissue processing. ...
