Once generated, the efficient delivery of EVs to the donor organ prior to transplantation remains an issue that could be resolved through the novel organ storage method ex vivo machine perfusion (EVMP). In this review, we summarize studies that have used tolerogenic cell-derived EVs to ameliorate hepatic IRI and promote liver allograft acceptance, discuss the steps toward generation of clinical-grade EVs, and introduce EVMP as a novel method to efficiently deliver EVs. To evaluate the shade match of three composite resin restorative materials to bi-layered acrylic teeth instrumentally and visually. Three composite materials-Omnichroma [OM], Tetric EvoCeram [TE], and TPH Spectra ST [TS] were placed into occlusal preparations (5 mm diameter, 2 mm depth) on 15 bi-layered acrylic teeth per each shade A2, B1, B2, C2, and D3. The composites were placed in a single increment and cured using Bluephase G2 light. The L*, a*, and b* readings were obtained using VITA Easyshade V for the teeth and restorations; mean ΔE values were calculated and assessed using two-way analysis of variance with a test of simple effects with multiple comparisons for significance (P < .05). Three teeth were restored to anatomical form with each of the composites for the five shades and were subjectively graded by 30 evaluators as 1-best match, 2-intermediate, and 3-poorest match. In the instrumental evaluation, OM and TS showed lower ∆E values for lighter shades, whereas TE showed lower and similar ∆E values for all shades. In the visual evaluation, TE exhibited the best shade match for darker shades C2 and D3. OM and TS matched better with lighter shades. Shade matching is composite and shade-dependent. Overall, TE matched the multiple shades better than the other two materials. Sing
