E-cigarette flavoring chemicals and vehicles adversely impact the functions of pigmented human retinal ARPE-19 cells [PDF]

open access: yesToxicology Reports
Electronic cigarettes (ECs) have been shown to adversely impact the human eye's retinal pigment epithelium (RPE). Flavored e-liquids induced cytotoxicity in unpigmented human ARPE-19 cells independent of nicotine's presence in my previous study.

Isolation and characterization of melanin from black garlic and sepia ink

open access: yesLWT - Food Science and Technology, 2019
Abstract Melanin was isolated from a plant source (black garlic: BG) and characterized and compared with melanin obtained from an animal source (sepia ink: SI). SEM observations showed that both melanins were spherical with the diameter of 100–1200 nm and 100–200 nm for BG and SI melanin, respectively.
