  • Water Content and Scatterers Dispersion Evaluation in Colorectal Tissues

    • Authors: Isa Carneiro, Sónia Carvalho, Rui Henrique, Luís Oliveira, Valery V. Tuchin
      First page: 040301
      Abstract: Optical clearing treatments reduce light scattering in biological tissues. Due to the heterogeneous composition of tissues, such high scattering is created by the refractive index mismatch between tissue fluids and scatterers. With the objective of collecting experimental data to predict and characterize the magnitude of the refractive index matching in optical clearing treatments, a series of studies were performed with colorectal tissues. The free water content in normal mucosa, muscle and pathological colorectal tissues was estimated, showing similar values for normal tissues and about 5% more in pathological tissue. The refractive index of the tissues was measured at various wavelengths between UV and NIR. This data was used to estimate the refractive dispersion curves for the various tissues, which were then combined with the free water contents to calculate the dispersion of scatterers in these tissues. These dispersions remain unchanged during optical clearing and by obtaining such spectral data, it is possible to quantify and characterize the refractive index matching mechanism in any optical clearing treatment to be applied in these tissues. The differences obtained between the experimental data of healthy and pathological tissues can also be used as a marker for cancer progression in ex vivo analysis.

  • Laser Speckle Modeling and Simulation for Biophysical Dynamics: Influence
           of Sample Statistics

    • Authors: Kosar Khaksari, Sean J. Kirkpatrick
      First page: 040302
      Abstract: Laser speckle is a statistical phenomenon and should be treated as such when establishing experimental parameters for using laser speckle techniques to infer information about the dynamics of a coherently illuminated medium, such as biological tissue. Herein, we demonstrate that when sampling (imaging) speckle patterns, it is critical that the sampled speckle patterns are unbiased estimators of the underlying random speckle field. If this condition is not met, the quality of the results will be compromised. Specifically, this study examines the effects of first and second order spatial statistics of speckle intensity images on laser speckle contrast imaging results. Finally, it is recommended that when using speckle techniques such as laser speckle contrast imaging, investigators should examine the first and second order spatial statistics of a speckle image prior to collecting actual data. If this examination reveals that the imaged speckle intensity image is not an unbiased estimator of the underlying random speckle field, then adjustments should be made to ensure that the images taken are unbiased estimators of the true speckle field.

  • Reversible photobleaching of photoconvertible SAASoti-FP

    • Authors: Ilya D. Solovyev, Alexandra V. Gavshina, Alexander P. Savitsky
      First page: 040303
      Abstract: SAASoti is a green fluorescent protein suitable for use in super-resolution microscopy as it can be photoconverted to red fluorescence under 405 nm illumination. The green fluorescence of V127T SAASoti variant is reversibly photobleached under exposure to 470 nm light without photoconversion to the red form. The phenomenon can be explained by chromophore protonation that was confirmed by an increase in absorption at 400 nm (chromophore protonated form) and a decrease at 509 nm (anionic form). This light-induced photoswitching can be repeated with the same sample several times without loss of the initial fluorescence intensity. Subsequent sample exposures result in the same fluorescence recovery process. By changing the content of the H-form one can control photoswitching as only the protonated SAASoti may be converted to the red form. This property is extremely important for sub-diffraction microscopy.

  • Study of the Changes of Gastric Wall Mucosa Optical Properties under the
           Impact of Aqueous Solutions of Haemoglobin and Glucose for Improving
           Conditions of the Laser Coagulation

    • Authors: Alexey N. Bashkatov, Elina A. Genina, Veniamin A. Grishaev, Sergey V. Kapralov, Vyacheslav I. Kochubey, Valery V. Tuchin
      First page: 040304
      Abstract: The paper presents the results of ex vivostudies of the possibility to control the absorption and scattering properties of the human gastric wall mucosa. For the first time we obtained the increase of the tissue absorption coefficient in the range 350-1250 nm by 2-4.5 times under the injection of haemoglobin solution with the concentration of 70 g/L into the mucosa. The observed increase of the absorbed energy fraction by nearly 65-90% was accompanied by almost 50-60% decrease of the penetration depth at the wavelengths of the sources widely used for laser ablation and coagulation of gastric mucosa paraplasms. Under the injection of 40% glucose solution into the mucosa, we observed the reduction of the absorption coefficient in the spectral region of water absorption bands approximately by 20% and the reduction of the transport scattering coefficient by nearly 24-27% in the spectral range 350-2500 nm. Increasing of the depth of laser radiation penetration in this case amounted to 15-17% in the range 800-1100 nm. The performed studies show the possibility in principle to control the optical parameters of the gastric wall tissues from the point of view of both varying the laser radiation penetration depth and regulating the tissue absorbance and, hence, the power of laser radiation, which, in turn, will allow more safety and less invasion in the course of laser therapeutic procedures.

  • Macro and micro spectroscopy parameters of cancerous and healthy
           gastrointestinal tissues

    • Authors: Tsanislava Genova, Ekaterina Borisova, Oksana Semyachkina-Glushkovskaya, Dmitry Gorin, Daniil Bratashov, Ivan Terziev
      First page: 040305
      Abstract: New more sensitive diagnostic modalities, for either analysis of biopsy tissue samples or on site, in vivo microscopy tissue examination, emerge to aid the detection and accurate diagnosis of gastrointestinal cancer. One of the most intensively investigated techniques is the fluorescence spectroscopy approach.We present our investigation of the detailed macro and micro fluorescence characteristics of ex-vivo fresh and fixed tissue samples. The fluorescence spectra of unprocessed cancerous and healthy gastrointestinal (GIT) tissue, obtained with two approaches fluorescence and synchronous fluorescence spectroscopy were compared with microspectroscopy performed with laser scanning confocal fluorescence microscopy (LSCFM) system in Lambda-scan regime over fixed tissue samples.The evaluated optical macro- and micro- spectroscopy characteristics are presented and disscused in order to improve the current understanding of the origin of autofluorescence contrast between healthy and cancerous tissues and its application for improvement of the existing diagnostic modalities.

  • Fluorescent diagnostics of benign breast diseases and breast cancer

    • Authors: Valeriya S. Maryakhina, Yulia S. Korneva, Igor V. Chekurov, Oksana A. Shisterova
      First page: 040306
      Abstract: In the study the spectra of fluorescence excitation and autofluorescence of histological sections with different pathological processes in breast were measured. Additionally, element composition of the tissues was investigated by scanning electron microscopy. It has been shown that spectra of fluorescence excitation of benign breast diseases (fibroadenoma and fibrocystic breast disease) have low maximum at 232 nm and high maximum at 260 nm. Also, fluorescence spectra of histological samples change during tumor growth and have two maxima (335 and 420 nm). The registered spectra are result of emission of such fluorophores as fatty acids, tryptophan, NADH, vitamin B6, collagen and bilirubin. The obtained spectral data correlate well with data of element analysis. Selenium status of the tissues was investigated by scanning electronic microscope. High concentration if selenium was detected only in fibroadenoma. In breast cancer samples and fibrocystic breast disease low selenium content was detected. It may confirm higher risk for malignant transformation of fibrocystic breast disease than fibroadenoma. Our results may be helpful for cancer diagnostics and for prognosis prediction.
