Dual-tracer background subtraction approach for fluorescent molecular tomography.
Diffuse fluorescence tomography requires high contrast-to-background ratios to accurately reconstruct inclusions of interest. This is a problem when imaging the uptake of fluorescently labeled molecularly targeted tracers in tissue, which can result in high levels of heterogeneously distributed background uptake. We present a dual-tracer background subtraction approach, wherein signal from the ...
متن کاملQuantitative Analysis of Calcium Spikes in Noisy Fluorescent Background
Intracellular calcium signals are studied by laser-scanning confocal fluorescence microscopy. The required spatio-temporal resolution makes description of calcium signals difficult because of the low signal-to-noise ratio. We designed a new procedure of calcium spike analysis based on their fitting with a model. The accuracy and precision of calcium spike description were tested on synthetic da...
متن کاملBeating Elo
where EA and EB are the expected outcomes for players A and B, and RA and RB are their ratings. Here we designate a win by 1, a loss by 0, and a draw by 0.5. The spread of the ratings is set by Λ, which for chess ratings is usually taken to be Λ = 400/ log(10) = 173.72. The result of each game updates each player’s rating according to an update rule. The update rule is usually based on the diff...
متن کاملNon-heart beating donors.
BACKGROUND Several groups have demonstrated that non-heart beating donation is a viable source of organs for transplantation. However, the theoretically worse graft function and survival of the kidneys obtained from non-heart beating donors (NHBDs) is still a matter of debate that has led to consider them as marginal donors for kidney transplantation. METHODS In this report, we compare the ou...
متن کاملDifferentiation of Enhanced Green Fluorescent Protein-Labeled Mouse Amniotic Fluid-Derived Stem Cells into Cardiomyocyte-Like Beating Cells.
BACKGROUND Amniotic fluid-derived stem cells (AFSCs) possess optimal differentiation potential and are a promising resource for cell therapy and tissue engineering. Mouse is a good model to be studied for pre-clinical research. METHODS In this study, we successfully established enhanced green fluorescent protein mouse-derived amniotic fluid stem cells (EGFP-mAFSCs) and investigated whether EG...
