Introduction: reactive oxygen species in health and disease

Physiologically induced changes in bound phenolics and antioxidants, DNA/cytoprotective potentials in pectic poly/oligosaccharides of tomato (Solanum lycopersicum)

“…Galectin‐3 is a crucial marker reported to be involved in metastasis progression of various types of cancer, while reactive oxygen species (ROS) are known to play a key role in the initiation and/or progression of various diseases such as atherosclerosis, diabetes, inflammatory injury, cancer, ulcer and cardiovascular diseases . Although several chemotherapeutic allopathic drugs are available in the market, they are prescribed only upon the onset of the disease.…”

One-pot synthesized Cu/Au/Pt trimetallic nanoparticles as a novel enzyme mimic for biosensing applications

“…This provided a sensitive colorimetric detection of H 2 O 2 which is of critical importance in the application elds of organic synthesis, food production, paper bleaching, pharmaceutical, clinical and environmental analysis 33 as well as in many biological processes like cell signaling. 34 By coupling the catalytic oxidation reaction of glucose by GOD, the colorimetric strategy was further applied for quantitative detection of glucose. The strategy showed great potentials as a universal tool for biosensing in view of the potential combination with diverse enzyme-related reactions.…”

Characteristics of the spin-trapping reaction of a free radical derived from AAPH: further development of the ORAC-ESR assay

“…The excess formation of reactive oxygen species (ROS) in the human body has been found to cause lifestyle-related disease [1,2]. Antioxidant substances, such as vitamins and polyphenols, in foods are essential to remove excess ROS and maintain a healthy life.…”
