Atomic scissors: a new method of tracking the 5-bromo-2'-deoxyuridine-labeled DNA in situ. [PDF]
A new method of the light microscopy detection of BrdU-labeled DNA in situ is described. It is based on the oxidative attack at the deoxyribose moiety by copper(I) in the presence of oxygen, which leads to the abstraction of hydrogen atom from ...

Catalytic Ammonia Oxidation to Dinitrogen by Hydrogen Atom Abstraction
AbstractCatalysts for the oxidation of NH3 are critical for the utilization of NH3 as a large‐scale energy carrier. Molecular catalysts capable of oxidizing NH3 to N2 are rare. This report describes the use of [Cp*Ru(PtBu2NPh2)(15NH3)][BArF4], (PtBu2NPh2=1,5‐di(phenylaza)‐3,7‐di(tert‐butylphospha)cyclooctane; ArF=3,5‐(CF3)2C6H3), to catalytically ...

ChemInform Abstract: THE REACTION OF HYDROGEN ATOMS WITH ACETYLENE [PDF]
Abstract The addition of hydrogen atoms to acetylene has been investigated at room temperature. The relative rate constant for &H+C_2H_4→C_2H_5, \labeleq1 &H+C_2H_2→C_2H_3, \labeleq2 was found to be k1/k2=9.99±0.16.

Human cytomegalovirus infection is common in normal prostate epithelium, prostate tumor tissue, and prostate cancer cell lines. CMV promotes cell survival, proliferation, and androgen receptor signaling. Anti‐CMV pharmaceutical compounds in clinical use inhibited cell expansion in prostate cancer models in vitro and in vivo, motivating investigation ...

Valence Tautomerism in Chromium Half-Sandwich Triarylmethylium Dyads
Valence tautomerism (VT) may occur if a molecule contains two chemically different redox-active units, which differ only slightly in their intrinsic redox potential.

Chromatin, which organizes DNA, changes its structure to adapt to stress like high oxygen levels (hyperoxia), which can damage cells. Researchers developed a technique to observe these changes and found variability in how different parts of chromatin remodel.
