Evidence for detrimental cross interactions between reactive oxygen and nitrogen species in Leber's hereditary optic neuropathy cells [PDF]
, 2015 Here we have collected evidence suggesting that chronic changes in the NO homeostasis and the rise of reactive oxygen species bioavailability can contribute to cell dysfunction in Leber’s hereditary optic neuropathy (LHON) patients.We report that ...

Nanoelectrodes for intracellular measurements of reactive oxygen and nitrogen species in single living cells [PDF]
Current Opinion in Electrochemistry, Elsevier, 2020, 22, pp.44-50, 2020 Reactive oxygen and nitrogen species (ROS and RNS) play important roles in various physiological processes (e.g., phagocytosis) and pathological conditions (e.g., cancer). The primary ROS/RNS, viz., hydrogen peroxide, peroxynitrite ion, nitric oxide, and nitrite ion, can be oxidized at different electrode potentials and therefore detected and ...

Granzymes in health and diseases: the good, the bad and the ugly
Frontiers in ImmunologyGranzymes are a family of serine proteases, composed of five human members: GA, B, H, M and K. They were first discovered in the 1980s within cytotoxic granules released during NK cell- and T cell-mediated killing.

Formation and Stabilization of Ground and Excited State Singlet O$_2$ upon Recombination of $^3$P Oxygen on Amorphous Solid Water [PDF]
J. Phys. Chem. Lett. 2020, 11, 6, 2171-2176, 2019 The recombination dynamics of $^3$P oxygen atoms on cold amorphous solid water to form triplet and singlet molecular oxygen (O$_2$) is followed under conditions representative for cold clouds. It is found that both, formation of ground state ($X ^3 \Sigma_{g}^{-}$) O$_2$ and molecular oxygen in the two lowest singlet states ($a ^1\Delta_g$ and $b ^1 ...

Non-lethal exposure to H2O2 boosts bacterial survival and evolvability against oxidative stress [PDF]
, 2020 Unicellular organisms have the prevalent challenge to survive under oxidative stress of reactive oxygen species (ROS) such as hydrogen peroxide (H2O2). ROS are present as by-products of photosynthesis and aerobic respiration.
