NDI based C2-symmetric Chiral Supramolecular Hydrogels Towards Enhanced Conductivity.

To comprehend the significance of improved conductive properties in C2-symmetric hydrogels, it is vital to investigate how non-gelating achiral functional group isomers influence the conductivity of such supramolecular hydrogels, whereas understanding the major driving forces behind this regulatory process is first and foremost.

Methyl Jasmonate Alleviated the Adverse Effects of Cadmium Stress in Pea ( L.): A Nexus of Photosystem II Activity and Dynamics of Redox Balance.

The accumulation of cadmium (Cd) in leaves reduces photosynthetic capacity by degrading photosynthetic pigments, reducing photosystem II activity, and producing reactive oxygen species (ROS). Though it was demonstrated that the application of Methyl Jasmonate (MeJA) induces heavy metal (HM) stress tolerance in plants, its role in adjusting redox balance and photosynthetic machinery is unclear. In this study, the role of MeJA in modulating photosystem II (PSII) activity and antioxidant defense system was investigated to reduce the toxic effects of Cd on the growth of pea ( L.

Role of Food Antioxidants in Modulating Gut Microbial Communities: Novel Understandings in Intestinal Oxidative Stress Damage and Their Impact on Host Health.

Dietary components have an important role on the structure and function of host gut microbial communities. Even though, various dietary components, such as carbohydrates, fats, proteins, fibers, and vitamins, have been studied in depth for their effect on gut microbiomes, little attention has been paid regarding the impact of several food antioxidants on the gut microbiome. The long-term exposure to reactive oxygen species (ROS) can cause microbial dysbiosis which leads to numerous intestinal diseases such as microbiota dysbiosis, intestinal injury, colorectal cancers, enteric infections, and inflammatory bowel diseases.
