ROS-Scavenging Nanomaterials to Treat Periodontitis [PDF]

Frontiers in Chemistry, 2020
The incidence of periodontitis is very high, and up to 45–50% of people are suffering from periodontitis. Periodontitis is caused by pathogens that invade teeth-supporting tissues such as gingiva, periodontal ligament, and alveolar bone.

Maize Peroxidase ZmPrx25 Modulates Apoplastic ROS Homeostasis and Promotes Seed Germination and Growth Under Osmotic and Drought Stresses

Antioxidants
Drought is one of the major abiotic stresses threatening maize production globally. Under drought stress, maize plants produce excessive reactive oxygen species (ROS), leading to oxidative damage.

The Nb4C3 MXenzyme Attenuates MASH by Scavenging ROS in a Mouse Model [PDF]

International Journal of Nanomedicine
The incidence of metabolic dysfunction-associated steatohepatitis (MASH) is increasing because people's dietary habits are dominated by high caloric intake and sedentary lifestyles, leading to the accumulation of lipid, reactive oxygen species (ROS) and inflammation. However, treating MASH remains a challenge.Two-dimensional (2D) niobium carbide (Nb4C3)

ROS‐Scavenging Multifunctional Microneedle Patch Facilitating Wound Healing [PDF]

Advanced Healthcare Materials
Abstract Chronic wounds often experience delayed healing due to a disrupted microenvironment marked by persistent inflammation and excessive fibrosiswhich leads to tissue dysfunction. Excessive mitochondrial reactive oxygen species (ROS) at the injury siteworsen this by hindering healing and promoting scarring.

The Role of Chalcogen in the ROS Scavenging Mechanism of Model Phenyl Compounds

Molecules
Phenolic compounds are important antioxidants with great ROS scavenging potential and the presence of the hydroxyl groups is fundamental for this chemical activity. Therefore, changing the chalcogen atom (oxygen) with any of its siblings of group 16 (sulfur, selenium and tellurium) may affect the reactivity of these compounds.

Reactive-oxygen-species-scavenging nanomaterials for resolving inflammation

Materials Today Bio, 2021
Reactive oxygen species (ROS) mediate multiple physiological functions; however, the over-accumulation of ROS causes premature aging and/or death and is associated with various inflammatory conditions.

Microvesicles: ROS scavengers and ROS producers [PDF]

Journal of Extracellular Vesicles, 2019
ABSTRACTThis review analyzes the relationship between microvesicles and reactive oxygen species (ROS). This relationship is bidirectional; on the one hand, the number and content of microvesicles produced by the cells are affected by oxidative stress conditions; on the other hand, microvesicles can directly and/or indirectly modify the ROS content in ...
