ROS (H2O2 in particular) are ubiquitous because they are metabolic by-products of cellular oxygen respiration, mostly through the accidental auto-oxidation of non-respiratory flavoproteins and the turnover of committed oxidases, in addition to those coming from environments2,3,4. To cope with ...
Reaction of the Oxygen Molecule at the Si(100)-SiO2 Interface During Silicon Oxidation Using constrained ab initio molecular dynamics, we investigate the reaction of the O2 molecule at the Si(100)-SiO2 interface during Si oxidation. The reaction proceeds sequentially through the incorporation of the...
The oxidation behavior of Nb held at a temperature of 725 °C and an air pressure of 1 × 10−4 Torr for 1 – 100 h was investigated. The changes of the oxygen solute concentration, the lattice parameter, the Vicker's microhardness and the bend ductility during the oxidation were ...
Oxidation Resistance 1(OXR1) gene is a highly conserved gene of the TLDc domain-containing family. OXR1 is involved in fundamental biological and cellular processes, including DNA damage response, antioxidant pathways, cell cycle, neuronal protection, and arginine methylation. In 2019, five patients...
In oxygen-deficient sea- water, nitrate is generally believed to be reduced in a stepwise manner to N2O or N2 (2NO3À-2NO2À- 2NO-N2O-N2) for the respiratory oxidation of organic matter. Known as heterotrophic denitrifica- tion, this process has been considered an important factor in...
Since Al Fata, Georgé, André, and Renard (2017) showed that a temperature over 100 °C is needed for vitamin C dehydration to become significant, the oxidation-reductive pathway was only considered. Moreover, the oxygen concentration was assumed constant at each temperature and therefore, not ...
Not only are vitamins involved in over 30 metabolic reactions, but they also play key roles in managing internal cellular stress, immunological defense systems and the overall health of animals.2 So, although they make up less than 1 percent of the diet,
Nitrogen fertilization is a key input in increasing rice production in East, South, and Southeast Asia. The introduction of high-yielding varieties has greatly increased the prospect of increasing yields, but this goal will not be reached without great increases in the use and efficiency of N on...
While reversible oxygen oxidation is an exciting direction to create high-capacity materials, high levels of oxygen redox can trigger oxygen loss from the Li-excess materials2, 8,9,10. The cations left behind by this process create cation-densified surface phases with poor Li-transport kinetics ...
Niemann-Pick type C disease is a rare neurodegenerative disorder mainly caused by mutations in NPC1, resulting in abnormal late endosomal/lysosomal lipid storage. Although microgliosis is a prominent pathological feature, direct consequences of NPC1 loss on microglial function remain not fully characte...
