Unlabelled: To develop multi-antioxidant systems for the preservation of meat products, mixtures of essential oils or plant extracts were investigated for their antioxidant interactions. The combinatorial study revealed that the chemical diversity of both major and minor components of these ingredients contributed to the antioxidant interactions. A shift from antagonistic or additive interaction to synergistic one was achieved by modulating the ratio of mono-components of multi-antioxidant systems. Mixtures containing oregano/thyme (25/50 of IC50), thyme/clove (25/100) and thyme/cinnamon (50/25) oils as well as cranberry/rosemary (25/25), cranberry/green tea (25/25), cranberry/apple (25/25), rosemary/apple (50/25) and grapeseed/cranberry (50/50) extracts have shown synergistic antioxidant effects. Among the investigated systems, thyme/clove oils and oregano/thyme oils/grape-seed extract systems have extended, in situ the shelf-life of chicken and ground pork products stored at 4 °C by 2 to 4 folds. The sensory acceptability of treated samples was rated to be moderately better than control. This study lays the ground for the development of efficient natural multi-antioxidant systems.

Excessive reactive oxygen species (ROS) can lead to the imbalance of antioxidant system in the body and cause oxidative damage to cells. It is imperative to rationally design nanomaterials with high catalytic activity and multiple antioxidant activities. Here, line peppers-derived carbon dots (CDs) is encapsulated into zeolitic imidazolate framework-8 (CDs@ZIF-8) to achieve enhanced antioxidant activities for improved protective effect on cells.

Stroke is a major contributor to global mortality and disability. While reperfusion is essential for preventing neuronal death in the penumbra, it also triggers cerebral ischemia-reperfusion injury, a paradoxical injury primarily caused by oxidative stress, inflammation, and blood-brain barrier disruption. An oxidative burst inflicts marked cellular damage, ranging from alterations in mitochondrial function to lipid peroxidation and the activation of intricate signalling pathways that can even lead to cell death.

With the aim to develop essential oil (EO) multi-antioxidant systems, combinatorial interactions of selected phenol and terpene-rich EOs (from Pimento Berry, Ceylon Cinnamon, Clove, Sage, White thyme; Oregano) enriched with individual polyphenols, crude plant extracts, and mixtures of their major polyphenols were investigated using single electron transfer (SET)-based DPPH and hydrogen atom transfer (HAT)-based ORAC assays. Polyphenols that enriched Eos the most favorably were rosmarinic acid (IC of 0.0891-0.

Infertility is defined as a couple's inability to conceive after at least one year of regular unprotected intercourse. This condition has become a global health problem affecting approximately 187 million couples worldwide and about half of the cases are attributable to male factors. Oxidative stress is a common reason for several conditions associated with male infertility.
