The disease phenotype in biliary atresia (BA) is caused by a fibro-inflammatory process leading to destruction of cholangiocytes, obstruction of ductular pathways and eventual progression to liver cirrhosis. The first line of management is a Kasai po

We demonstrate pulsed, photopumped multimode laser emission in the visible spectral range from rhodamine B dye dissolved in various solvents. The laser emission is characterized by a well-defined, low threshold pump power at which the emission spectr
