The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, EarlyView.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

Green‐lighting biofuels from microalgal lipids: A review of strategies to integrate stress into continuous cultures

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 1196-1210, March/April 2026.
Abstract The vision of using microalgae to obtain organic chemicals in a carbon‐neutral manner is intriguing. It promises to produce various substances including biofuels by photosynthesis, without competing with agricultural land. Processes have been established whereby microalgae undergo a growth phase followed by a stress phase, which induces lipid ...

Hydrolytic efficiency and isomerization during de-esterification of natural astaxanthin esters by saponification and enzymolysis

Electronic Journal of Biotechnology, 2018
Background: Astaxanthin from natural sources is typically esterified with fatty acids; hence, it must be hydrolyzed to remove esters before identification and quantification by conventional HPLC.
