Magnetic Isotope Effect in the Uranium Isotopes Separation [PDF]

open access: yesarXiv, 2018
When uranyl nitrate is photolysed in the water solution, light isotope ${}^{235}{\rm U}$ is separated from isotope ${}^{238}{\rm U}$ ; an enrichment factor $K = 1.04$ . The initial samples were depleted by a light isotope of uranium ${}^{235}{\rm U}$ (degree $\beta = 0.00455$). Regenerated uranyl nitrate was enriched by an isotope of uranium ${}^{235}{\

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Bacterial nitrate reductases: Molecular and biological aspects of nitrate reduction

open access: yesJournal of Inorganic Biochemistry, 2006
Nitrogen is a vital component in living organisms as it participates in the making of essential biomolecules such as proteins, nucleic acids, etc. In the biosphere, nitrogen cycles between the oxidation states +V and -III producing many species that constitute the biogeochemical cycle of nitrogen.

Does a glycine sodium nitrite crystal exist? [PDF]

open access: yesarXiv, 2015
The glycine sodium nitrite crystal reported by Khandpekar and Pati in the paper entitled, Synthesis and characterisation of glycine sodium nitrite crystals having non linear optical behaviour, Opt Commun 285, 2012 288-293 is actually gamma-glycine. In addition, we show that glycine barium ammonium nitrate, glycine sodium zinc sulfate, glycine barium ...
