Antenna complexes protect Photosystem I from Photoinhibition

BMC Plant Biology, 2009
Background Photosystems are composed of two moieties, a reaction center and a peripheral antenna system. In photosynthetic eukaryotes the latter system is composed of proteins belonging to Lhc family. An increasing set of evidences demonstrated how these

Photoprotection of the future: challenges and opportunities [PDF]

, 2020
The use of sunscreens is an important and essential component of photoprotection. Since their introduction during the first half of the last century, sunscreens have benefited enormously from major technological advances such as the development of novel ...

Systemic Photoprotection in Skin Cancer Prevention: Knowledge among Dermatologists

Biomolecules, 2021
Background: Systemic photoprotection (i.e., administration of substances such as nicotinamide, carotenoids, and vitamin D) may be important to reduce photocarcinogenesis or to support long-term protection against UV irradiation.

Manganese Oxide Nanoclusters for Skin Photoprotection

, 2019
An ultraviolet (UV) filter is the core component of sunscreen and protects skin from various photo damages. Current UV filters are hampered by skin penetration, poor photostability, photocatalytic generation of harmful reactive oxygen species (ROS), and ...

Widening the landscape of transcriptional regulation of algal photoprotection

, 2022
Availability of light and CO 2 , substrates of microalgae photosynthesis, is frequently far from optimal. Microalgae activate photoprotection under strong light, to prevent oxidative damage, and the CO 2 Concentrating Mechanism (CCM) under low CO 2 , to ...

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

Advanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.

Investigating isomer specific photoprotection in a model plant sunscreen

, 2018
International audienceSinapate esters are used throughout the plant kingdom, for example in photoprotection from ultraviolet radiation. Sinapate esters are naturally produced in their E-isomeric form; however, upon exposure to ultraviolet radiation ...

Sodium Ascorbate‐Accelerated Gelling Hydrogels With Rapid Self‐Mineralized Capacity for Chronic Wounds

Advanced Science, EarlyView.
An immunoregulatory hydrogel based on sodium ascorbate (SA)‐accelerated gelation and in situ self‐mineralization is prepared here. Such a hydrogel is constructed by mixing benzaldehyde‐ and cyanoacetate‐functionalized dextran with silver nitrate (AgNO3) and SA, enabling the ultrafast solidification and in situ self‐mineralization of silver ...
