Reactive oxygen species

Did you know oxidative stress can be extremely harmful to the human? Learn all about oxidative stress and ways to prevent it.

Recently, it was proposed that there is a common mechanism behind the activity of bactericidal antibiotics, involving the production of reactive oxygen species (ROS). However, the involvement of ROS in antibiotic-mediated killing has become the subject of much debate. In the present review, we provide an overview of the data supporting the ROS hypothesis; we also present data that explain the contradictory results often obtained when studying antibiotic-induced ROS production. For this…

N6-Etheno 2'-deoxyadenosine is a reactive oxygen species (ROS)/reactive nitrogen species (RNS)-induced DNA oxidation product, used as a biomarker to evaluate chronic inflammation and lipid peroxidation in animal or human tissues. - Mechanism of Action & Protocol.

Communications between cell organelles are pivotal to resolve cellular stress and dysregulated signaling. The physiological processes inside cells generates several byproducts that may impose stress to the cells. Indeed, mitochondrial dysfunction during biochemistry of ATP synthesis generates excessive reactive oxygen species (ROS) that may cause cellular aging and disease.The mitochondrial electron transport chain (ETC) associated respiratory complexes are the major source of reactive…

Recent studies have demonstrated that ROS have key roles in seed germination particularly in the release of seed dormancy and embryogenesis.

A new study reveals just how the bacteria thrive deep in muscle tissue and cause such severe disease.

Inflammation in Alzheimer's disease. The Aβ peptide produced by APP processing, form aggregates that activate microglia through TLRs and RAGE receptors. These receptors in turn, activate NF-κ B and AP-1 transcription factors, which induce the reactive oxygen species (ROS) production and the expression of inflammatory cytokines (IL-1, IL-6, TNF). These inflammatory factors directly acting on the neurons and also stimulate the astrocytes, which amplify the pro-inflammatory signals, inducing a…
