Singlet oxygen (1O2) is a biologically relevant reactive oxygen species capable of efficiently
reacting with cellular constituents. The resulting oxidatively generated damage to nucleic …

Photodynamic therapy (PDT) can be developed into an important arsenal against cancer; it
is a minimally invasive therapy, which is used in the treatment or/and palliation of a variety of …

Proteins comprise approximately 68% of the dry weight of cells and tissues and are
therefore potentially major targets for oxidative damage. Two major types of processes can …

The selective in vitro anti-tumor mechanisms of cold atmospheric plasma (CAP) and plasma-
activated media (PAM) follow a sequential multi-step process. The first step involves the …

The word “antioxidant” means different things to different people. Often (eg by food
scientists) the term is implicitly restricted to chain-breaking inhibitors of lipid peroxidation …

Nitrite and H 2 O 2 are long-lived species in cold atmospheric plasma and plasma-activated
medium. It is known that their synergistic interaction is required for selective apoptosis …

Abstract Melatonin (N-acetyl-5-methoxytryptamine), an endogenously produced indole
found throughout the animal kingdom, was recently reported, using a variety of techniques …

Although oxygen is a powerful oxidant, the triplet ground state of dioxygen constitutes a
kinetic barrier for oxidation of biological molecules, which are mostly singlet state (1) …

Catalases, heme enzymes which catalyze decomposition of hydrogen peroxide to water and
molecular oxygen, are important members of the antioxidant defense system of cells of …

Abstract Singlet oxygen (1 O 2) is believed to be generated in biological systems by a range
of endogenous processes (eg. enzymatic and chemical reactions) and exogenous stimuli …
