In vivo measurements of cutaneous melanin across spatial scales: using multiphoton microscopy and spatial frequency domain spectroscopy.
The combined use of nonlinear optical microscopy and broadband reflectance techniques to assess melanin concentration and distribution thickness in vivo over the full range of Fitzpatrick skin types is presented. Twelve patients were measured using multiphoton microscopy (MPM) and spatial frequency domain spectroscopy (SFDS) on both dorsal forearm and volar arm, which are generally sun-exposed ...
متن کاملIn vivo isolation of the effects of melanin from underlying hemodynamics across skin types using spatial frequency domain spectroscopy.
Skin is a highly structured tissue, raising concerns as to whether skin pigmentation due to epidermal melanin may confound accurate measurements of underlying hemodynamics. Using both venous and arterial cuff occlusions as a means of inducing differential hemodynamic perturbations, we present analyses of spectra limited to the visible or near-infrared regime, in addition to a layered model appr...
متن کاملSpatial ecology across scales.
The international conference 'Models in population dynamics and ecology 2010: animal movement, dispersal and spatial ecology' took place at the University of Leicester, UK, on 1-3 September 2010, focusing on mathematical approaches to spatial population dynamics and emphasizing cross-scale issues. Exciting new developments in scaling up from individual level movement to descriptions of this mov...
متن کاملCombining Information Across Spatial Scales
Spatial and spatial-temporal processes in the physical, environmental, and biological sciences often exhibit complicated and diverse patterns across different spacetime scales. Both scientific understanding, often reflected in computer models, and observational data vary in form and content across scales. We develop and examine a Bayesian hierarchical framework by which the combination of such ...
متن کاملIn vivo spatial frequency domain spectroscopy of two layer media.
Monitoring of tissue blood volume and local oxygen saturation can inform the assessment of tissue health, healing, and dysfunction. These quantities can be estimated from the contribution of oxyhemoglobin and deoxyhemoglobin to the absorption spectrum of the dermis. However, estimation of blood related absorption in skin can be confounded by the strong absorption of melanin in the epidermis and...
