Combined Effects of Carotenoids and Polyphenols in Balancing the Response of Skin Cells to UV Irradiation

open access: yesMolecules, 2021
Oral carotenoids and polyphenols have been suggested to induce photo-protective effects. The aim of the study was to test whether the combination of carotenoids and polyphenols produce greater protective effects from UV-induced damage to skin cells. Such

STRESS CORROSION CRACKING SAMBUNGAN LAS CDW SS 316L DAN ASTM A36 DALAM VARIASI SUHU LINGKUNGAN KOROSIF FeCl2

open access: yesRekayasa Mesin, 2023
Stress Corrosion Cracking (SCC) is known as a trigger for material failure, especially in Dissimilar Metal Welding (DMW). Although DMW promises wide application in structural design, it is found that there is high SCC mitigation making it prone to ...

The Influence of Motion and Stress on Optical Fibers

open access: yes, 2013
We report on extensive testing carried out on the optical fibers for the VIRUS instrument. The primary result of this work explores how 10+ years of simulated wear on a VIRUS fiber bundle affects both transmission and focal ratio degradation (FRD) of the

Green tea and cocoa enhance cognition in Lymnaea

open access: yesCommunicative & Integrative Biology, 2018
A flavonoid, (-)-epicatechi (Epi), enhances long-term memory (LTM) formation in Lymnaea and reverses memory obstruction caused by stress. Many foods contain substantial amounts of Epi, (e.g. green tea and cocoa).

Cell-based assays to identify novel retinoprotective agents

open access: yesMethodsX, 2020
Degeneration of the retina can lead ultimately to devastating irreversible vision loss, such as in inherited retinitis pigmentosa and age-related macular degeneration. Currently there is no cure to prevent retinal degeneration.
