Dihydrocaffeic Acid Prevents UVB‐Induced Oxidative Stress Leading to the Inhibition of Apoptosis and MMP‐1 Expression via p38 Signaling Pathway

open access: yesOxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Chronic UVB exposure promotes oxidative stress, directly causes molecular damage, and induces aging‐related signal transduction, leading to skin photoaging. Dihydrocaffeic acid (DHCA) is a phenolic compound with potential antioxidant capacity and is thus a promising compound for the prevention of UVB‐induced skin photodamage.

Does the Polymorphism in the Length of the Polyalanine Tract of FOXE1 Gene Influence the Risk of Thyroid Dysgenesis Occurrence?

open access: yesJournal of Thyroid Research, Volume 2017, Issue 1, 2017., 2017
Background. Recent data have suggested that polymorphisms in the length of the polyalanine tract (polyA) of FOXE1 gene may act as a susceptibility factor for thyroid dysgenesis. The main purpose of this study was to investigate the influence of polyA of FOXE1 gene on the risk of thyroid dysgenesis. Method. A case‐control study was conducted in a sample
