OBJECTIVES The purpose of this study was to compare in-vitro the amount of debris extruded apically from extracted teeth, using K3, Protaper rotary instruments and manual step-back technique. METHODS Forty five human single-rooted mandibular premolar teeth were randomly divided into 3 groups. The teeth in 3 groups were instrumented until reaching the working length with K3, Protaper rotary in...
Transcellular Ca2+ transport in the distal nephron involves passive Ca2+ influx at the apical membrane, diffusion through the cytosol and active extrusion across the opposing basolateral membrane. The molecular identity of the apical Ca2+ entry step is still elusive, but its regulatory aspects have been analyzed in the present study. To this end, rabbit connecting and cortical collecting tubula...
This study provides the first information about pHi regulatory mechanisms in human retinal pigment epithelium (RPE). The experiments were carried out on fresh explant tissues from adult donor and fetal eyes, and pHi was measured using fluorescence microscopy techniques and the pH-sensitive dye 2',7'-bis(carboxyethyl)-5(6)-carboxyfluorescein. In adult donor RPE, the resting pHi is 7.30 +/- 0.14 ...
