The slides were microwaved in SPOT-Light Tissue Heat Pretreatment Buffer for 10 min at 92°C and washed for 3 min twice in phosphate-buffered saline (PBS).
They were covered with 100 μl SPOT-Light Tissue Pretreatment Enzyme for 10 min at 37°C and washed for 2 min three times in PBS at room temperature.
For the determination of O2 saturation of Hb (SO2Hb) and relative Hb concentration (rHb), white-light tissue spectrometry was utilised: SO2Hb is identified by the colour of Hb, as the degree of molecular SO2Hb relates to a certain colour.
Briefly, heat pre-treatment of deparaffinised sections were incubated for 15 min at 98 °C in CISH pre-treatment buffer (SPOT-light tissue pre-treatment kit, Zymed Laboratories, San Francisco, CA, USA) and digested with pepsin for 6 min at room temperature according to the manufacturer's instructions.
Heat pretreatment of deparaffinised sections consisted of incubation for 15 minutes at 98°C in CISH pretreatment buffer (SPOT-light tissue pretreatment kit; Zymed (South San Francisco, CA, USA) and digestion with pepsin for 5.5 minutes at room temperature according to the manufacturer's instructions.
A second threshold is set to determine the area of dense tissue within the breast, which is the lightest tissue visible on the mammogram.
The numerical results support our findings based on the theoretical derivations and suggest that CH models should play a useful role in modeling light-tissue interactions.
The optical characterization (absorption coefficient, scattering coefficient and anisotropy factor) of porcine skin tissue can help in a better understanding of the light-tissue interaction, more efficient instrumental sensor designs and data modeling.
Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
Photons can be very useful things for medical applications: Photons can travel through tissues, probing the tissue through various light-tissue interactions and eventually carrying the information back to the tissue surface for subsequent optoelectronic detection.
