claimPlant-derived chemicals, including quinones and polyphenols, produce reactive oxygen species in microbial cells, which surpass antioxidant defenses and induce oxidative damage.
claimReactive oxygen species produced by plant-derived chemicals inflict damage on microbial DNA, proteins, and lipids, resulting in cellular apoptosis.
claimHoney flavonoids and quercetin impede the growth of Candida albicans by increasing intracellular reactive oxygen species levels.
claimBerberine induces elevated reactive oxygen species generation in Streptococcus pyogenes.
claimThe flavonoid baicalein induces reactive oxygen species buildup and consequent cell death in Candida species.
claimCatechin exhibits antibacterial efficacy against Gram-positive and Gram-negative bacteria by inducing reactive oxygen species subsequent to membrane permeabilization.
Immunity In Depth | Linus Pauling Institute lpi.oregonstate.edu 5 facts
claimVitamin C protects leukocytes from autooxidation damage caused by the reactive oxygen species they release.
claimGlutathione peroxidases (GPx) are selenoproteins that function as redox regulators and cellular antioxidants by reducing reactive oxygen species, such as hydrogen peroxide and lipid hydroperoxides, to harmless products like water and alcohols through the oxidation of glutathione.
claimSufficient iron is critical for the differentiation and proliferation of T lymphocytes and the generation of reactive oxygen species (ROS) that kill pathogens.
claimVitamin C is an antioxidant that protects cells against reactive oxygen species generated by immune cells to kill pathogens.
claimReactive oxygen species released by phagocytic leukocytes to kill pathogens can cause damage to the leukocytes themselves.
The role of light in regulating plant growth, development and sugar ... frontiersin.org Jan 6, 2025 3 facts
claimGreen light treatment in Cucumis melo seedlings regulates stomata, improves water utilization, increases plant height and fresh weight, and reduces leaf stomatal conductance and reactive oxygen species content, which improves drought tolerance.
claimPlant growth is strongest at 75% irradiation because this level increases photosynthesis, reduces the accumulation of reactive oxygen species, and maintains stomata and chloroplast structure (Ma et al., 2015).
claimPlants grown under full light conditions suffer from photoinhibition due to overlighting, while plants grown under 25% irradiance experience light deficiency, both of which cause chloroplast swelling, irregular seed shape, reduced lamellae, and disintegration of the cyst-like membrane system due to lipid peroxidation and reactive oxygen species (ROS) accumulation (Ma et al., 2015).
Research reveals devastating impact of Western diet on human health news-medical.net Jun 18, 2023 2 facts
claimThe widespread circulation of free radicals, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS), can directly damage DNA, proteins, and lipids, leading to cell dysfunction and death.
claimThe Western diet is often high in pro-oxidant compounds that increase the production of free radicals, such as reactive oxygen species (ROS) and reactive nitrogen species (RNS), leading to increased oxidative stress throughout the body.
The Role of Immune Cells in Inflammation jmolpat.com 2 facts
claimNeutrophils are highly phagocytic and engulf and kill invading pathogens through the production of Reactive Oxygen Species (ROS) and other toxic substances.
claimThe release of Reactive Oxygen Species (ROS) and other toxic molecules by neutrophils can damage nearby healthy tissues, leading to a self-amplifying cycle of tissue injury and inflammation.
Medicinal plants and human health: a comprehensive review of ... link.springer.com Nov 5, 2025 1 fact
claimEndothelial dysfunction contributes to heart failure development by disrupting endothelial nitric oxide synthase (eNOS) activity, which reduces nitric oxide availability, increases reactive oxygen species production, and activates inflammatory cascades involving NF-κb signaling and the expression of adhesion molecules ICAM1 and VCAM1.
Phytochemical and Pharmacological Studies of Traditionally Used ... heraldopenaccess.us 1 fact
claimEstragole, linalool, eugenol, and methyl cinnamate in Ocimum basilicum Linn. exhibit anti-fungal activity by reducing DNA binding formation of aflatoxins, reacting with reactive oxygen species (ROS) increased by aflatoxins, and inhibiting mycelium growth, spore germination, and germ tube elongation, according to Gucwa et al. and Nugroho et al.
Healthy vs. Infected Wounds: A Clinician's Guide - Net Health nethealth.com Jun 24, 2025 1 fact
quote“Infection at the site of the wound [results] in excessive recruitment of inflammatory cells,” and these infections “result in increased release of reactive oxygen species that are damaging to the tissue and can also result in the formation of biofilms, which contribute to poor wound healing and are caused by bacterial toxins.”
Chronic Inflammation - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 1 fact
claimNeutrophils destroy antigens through phagocytosis and the release of reactive oxygen species and cytokines, including IL-1, IL-6, and TNF-α.

referenceF. Conforti et al. published a study in 2009 in Food Chemistry regarding the protective ability of Mediterranean dietary plants against oxidative damage, specifically examining the role of radical oxygen species in inflammation and the content of polyphenols, flavonoids, and sterols.
