Antiaging Effects of Urolithin A on Replicative Senescent Human Skin Fibroblasts.

Although the health benefits attributed to urolithin A, such as anticancer, anti-inflammatory, and antioxidant effects, are based on numerous, diverse studies carried out , the biological effects of urolith A are still not entirely understood. In this study, we explored the biological effects of urolithin A using senescent human skin fibroblasts (HSFs) to determine whether urolithin A has any antiaging potential. Our results showed that urolithin A significantly increased type I collagen expression and reduced matrix metalloproteinase 1 (MMP-1) expression.

Comparison of deformation texture in FePd alloy via X-ray diffraction and electron backscatter diffraction techniques.

In this work, textures measured by electron backscatter diffraction (EBSD) and X-ray diffraction in rolled FePd alloys were compared. The effect of scanning size used for EBSD measurements was investigated. The correlation coefficient was first proposed to quantify the similarity of the orientation density profile along the α- and β-fibers after cold rolling.
