Abstract: Methods, devices and systems for quantifying fluorescence and optical properties in a turbid medium such as tissue are disclosed. One of the methods comprises: providing fluorescence emission and reflectance wavelengths detected from a target surface where each of the detected wavelengths is associated with a respective known distance between a respective excitation source giving rise to the respective detected wavelength and a detector detecting the respective detected wavelength; and calculating the optical properties based on the detected wavelengths and the respective known distances. The known distances may be predetermined to enable calculation of a desired range of values for the optical properties. The calculation of the optical properties may be based on a model of light interaction with the turbid medium where the model limits a range of calculated values for the optical properties.

Abstract: Various embodiments are described herein for a system and a method for identifying a region of interest in tissue using mass spectrometry. An agent administration component can be provided to administer an exogenous agent to the tissue. A sampling unit can also be provided to acquire a sample from the tissue. The sample can then be provided to a high sensitivity analysis platform, such as a mass analyzer, to analyze the sample and determine a distribution of the exogenous agent or a by-product of the exogenous agent within the tissue based on the analysis. The analysis platform can then identify the region of interest based on the distribution of the exogenous agent or the distribution of the by-product.

Abstract: A locking member for a gate apparatus comprises a body mountable to a gripping array of a support, said body having a mating form mutually engageable with the gripping array, whereby axial motion of said body relative to said gripping array is inhibited. A member extends away from said body, said member defining a cross-tie mount for receiving a mating end of a cross-tie. The cross-tie mount has a cross-tie end retainer which is movable between a first position securing said cross-tie in said cross-tie mount, and a second position permitting release of said cross-tie from said cross-tie mount, whereby the cross-tie may be moved to function as a gate.
