Evidence-Based Complementary and Alternative Medicine, Volume 2020, Issue 1, 2020., 2020 Purpose. Retinal ischemia is a medical condition associated with numerous retinal vascular disorders, such as age‐related macular degeneration, glaucoma, and diabetic retinopathy. This in vitro cell and in vivo animal study investigated not only the protective effect of S‐allyl L‐cysteine (SAC, an active component of garlic) against retinal ischemia ...

Journal of Materials Research and Technology, 2021 Soft zone formation in dissimilar Cr–Mo welding occurs during post weld heat treatment that could compromise the integrity of the weldment. The decomposition of martensite could cause this formation at the weld heat affected zone adjacent to the fusion boundary. There could not yet determine the actual width of this zone.
