    2. Staging of development in Terrien’s degeneration based on corneal curvatures detected by optical coherence tomography

      Staging of development in Terrien’s degeneration based on corneal curvatures detected by optical coherence tomography
      Purpose We aimed to explore a new classification system based on the change of focal corneal curvatures and corneal thickness in Terriens corneal degeneration with optical coherence tomography. Methods This was a cross-sectional study. Ninety eyes of 59 patients with Terriens degeneration were examined with slit lamp biomicroscopy, Orbscan II corneal tomography and the Visante OCT system, and were staged according to Svegess classification. Results The ratio of female to ...

    3. Effects of titanium dioxide nanoparticles coupled with diode laser on optical properties of in vitro normal and cancerous human lung tissues studied with optical coherence tomography and diffuse reflectance spectra

      Effects of titanium dioxide nanoparticles coupled with diode laser on optical properties of in vitro normal and cancerous human lung tissues studied with optical coherence tomography and diffuse reflectance spectra
      The objective is to investigate the effects of two different sized (60 and 100 nm) titanium dioxide ( TiO 2 ) nanoparticles (NPs) penetration and accumulation in in vitro human normal lung (NL) tissue, lung squamous cell carcinoma (LSCC) tissue, and 650-nm diode laser-pretreated tissue on their optical properties studied with optical coherence tomography monitoring and diffuse reflectance (DR) spectra measurement. As with TiO 2 NPs penetrating into the tissues, the intensities ...

    4. Influence of nanoparticles accumulation on optical properties of human normal and cancerous liver tissue in vitro estimated by OCT

      Influence of nanoparticles accumulation on optical properties of human normal and cancerous liver tissue in vitro estimated by OCT
      In this work, the potential use of nanoparticles as contrast agents by using spectral domain optical coherence tomography (SD-OCT) in liver tissue was demonstrated. Gold nanoparticles (average size of 25 and 70nm), were studied in human normal and cancerous liver tissues in vitro , respectively. Each sample was monitored with SD-OCT functional imaging for 240min. Continuous OCT monitoring showed that, after application of gold nanoparticles, the OCT signal intensities of normal ...

    5. Monitoring of permeability of different analytes in human normal and cancerous bladder tissues invitro using optical coherence tomography

      Monitoring of permeability of different analytes in human normal and cancerous bladder tissues invitro using optical coherence tomography
      We report our preliminary results on quantification of glucose and dimethyl sulfoxide (DMSO) diffusion in normal and cancerous human bladder tissues in vitro by using a spectral domain optical coherence tomography (SD-OCT). The permeability coefficients (PCs) of a 30% aqueous solution of glucose are found to be (7.92 0.81) 10 -6 cm s -1 and (1.19 0.13) 10 -5 cm s -1 in normal and cancerous ...

    7. Influence of different sized nanoparticles combined with ultrasound on the optical properties of invitro normal and cancerous human lung tissue studied with OCT and diffuse reflectance spectra

      Influence of different sized nanoparticles combined with ultrasound on the optical properties of invitro normal and cancerous human lung tissue studied with OCT and diffuse reflectance spectra
      The present study is concerned with the in vitro study of different sized titanium dioxide (TiO 2 ) nanoparticles' (NPs) penetration and accumulation in human normal lung (NL) tissue and lung adenocarcinoma tumor (LAT) tissue by the methods of continuous optical coherence tomography (OCT) monitoring and diffuse reflectance (DR) spectra measurement, and their evaluating the effects of TiO 2 NPs in two sizes (60nm and 100nm) and their combination with ultrasound ...

    8. Effect of differently sized nanoparticles' accumulation on the optical properties of ex vivo normal and adenomatous human colon tissue with OCT imaging and diffuse reflectance spectra

      Effect of differently sized nanoparticles' accumulation on the optical properties of ex vivo normal and adenomatous human colon tissue with OCT imaging and diffuse reflectance spectra
      Using optical coherence tomography (OCT) and diffuse reflectance spectra, we investigated the dynamics of titanium dioxide (TiO 2 ) nanoparticles, of different sizes, when penetrating and accumulating in human normal colon tissue (NC) and adenomatous colon tissue (AC). The process of nanoparticle penetration and accumulation in biotissue is accompanied by changes in the optical properties of tissue. Continuous OCT monitoring showed that, after application of TiO 2 nanoparticles, the OCT signal ...
