A new pulsatile flow visualization method using a photochromic dye with application to Doppler ultrasound.

Ann. Biomed. Eng. 14(3) , 203-18, (1986)

A nonintrusive method for the visualization of pulsatile flow velocity profiles is described. The method is based on the use of a photochromic dye that is added to the fluid being studied and a nitrogen laser which excites the dye producing a marker "line" wh...

Mast cells involvement in the inflammation and fibrosis development of the TNBS-induced rat model of colitis.

Scand. J. Gastroenterol. 37(3) , 330-7, (2002)

Mast cells have been implicated in chronic inflammatory conditions resulting in fibrosis, such as Crohn disease. However, a link between inflammation, fibrosis and mast cells has not been demonstrated in human or animal intestinal diseases. This work was unde...

Direct structural determination of conformations of photoswitchable molecules by laser desorption-electron diffraction.

Angew. Chem. Int. Ed. Engl. 49(37) , 6524-7, (2010)

Estimation of surface polarity of silicas by absorption spectroscopy of glycerin suspensions of adsorbed 6-nitrobenzoindolinopyran.

Pharm. Res. 4(5) , 398-401, (1987)

The title compound (6-NO2-BIPS) is adsorptiochromic, becoming colored upon adsorption to a polar surface. Powders of 6-NO2-BIPS adsorbed to silica gel or silicic acid are suspended in glycerin, and the absorption spectrum of the adsorbate is recorded by conve...

Photochromic flow visualization for the investigation of artificial heart valves.

Int. J. Artif. Organs 16(3) , 146-50, (1993)

A new method for the investigation of hydrodynamics of artificial heart valves is presented. It is a method of flow visualisation. The photochromic flow visualization method is based on activation of color tracers in originally colorless photochromic solution...
