  • Patent number: 10920260
    Abstract: Mitochondrial function is measured. Repetitive or continuous measurements are performed of prompt red fluorescence, emerging from the skin due to PpIX build up, and/or delayed fluorescence of PpIX. An estimate of the rate of PpIX generation is used as an indicator of mitochondrial integrity and ATP availability. Mitochondrial oxygen tension is determined from the delayed fluorescence lifetime of PpIX. When blood supply to the measurement volume is interrupted or reduced, the resulting changes to the mitochondrial oxygen tension allow an estimation of information about the kinetics of oxygen consumption in the mitochondria, such as the maximum rate of oxygen consumption as well as the Michaelis-Menten constant, providing information about the oxygen affinity of the mitochondrial respiratory chain.

  • Patent number: 10531818
    Abstract: Method and instrument for analysing a tissue sample. Localized concentrations of an analyte are measured at a plurality of spaced apart locations around a controlled depth. Spatial variance of the analyte is calculated based on the measured analyte concentrations. The procedure is repeated while varying the controlled depth to obtain the spatial variance as a function of depth. Tissue at a particular depth may be evaluated as tumour tissue when the spatial variance is below the threshold. For example, a section distance is calculated between the tissue surface and a depth where the measured spatial variance crosses a predetermined threshold variance. Feedback can be provided based on a comparison between a calculated section distance and a pre-set minimum section margin.
