Figure 4
Synchrotron WFUV allows detection of CaOx microcrystallites in kidney biopsies. The bright spot in the 412–438 nm channel (A), indicated by the arrowhead, corresponds to a focal shadow in the 327–353 nm channel (B) resulting in a strong yellow spot after signal subtraction (C). (D) Frequency of the semi-quantitative microcrystal score [0: no crystal; 1: scarce crystals (<3 per map); 2: few crystals (3–10 per map); 3: numerous microcrystals (>10 per map)] in PHO, SHO and KLTPHO and control biopsies. *** p < 0.001; ** p < 0.01; * p < 0.1. |
