Non-contrast quantitative study of brain perfusion changes in multiple sclerosis [PDF]
Digital DiagnosticsBACKGROUND: Non-contrast magnetic resonance perfusion can identify areas of cerebral perfusion changes in patients with multiple sclerosis, even in the absence of focal lesions [1]. This technique offers several advantages, including non-invasiveness [2]

Phantoms for performance assessment of optical coherence tomography systems [PDF]
, 2012 In this paper, we describe the procedures to make epoxy resin and agarose phantoms designed using Mie scattering calculations. The phantoms are constructed to be used in the estimation of point spread function (PSF) of an optical coherence tomography ...

Nicotinamide adenine dinucleotide reduced (NADH) is a natural UV filter of certain bird lens
Scientific Reports, 2022 In this work, we for the first time report the identification of UV filters in the bird eye lens. We found that lenses of some raptors (black kite, common buzzard) and waterfowl (birds from Podicipedidae family) contain unusually high levels of reduced ...
