TTP as Tumor Suppressor and Inflammatory Regulator in Oral Carcinogenesis.

The stability of messenger RNA (mRNA) is controlled by proteins that bind to adenosine-uridine-rich sequences (AREs) in their 3' untranslated regions (3'UTR), known as AU-binding proteins. One of these proteins is tristetraprolin (TTP; encoded by ), which promotes degradation of mRNAs with AREs in their 3'UTR. TTP accelerates the decay of its target transcripts, many of which encode proinflammatory mediators that promote tumorigenesis.

NO Activation and NO Adsorption Control the Simultaneous Conversion of NO and NO Using NH over Fe-ZSM-5.

Fe-exchanged zeolites are heterogeneous catalysts that can potentially ensure simultaneous conversion of nitrous oxide (NO) and nitric oxide (NO) using ammonia (NH) as a selective reducing agent through their selective catalytic reduction reaction (NO-NO-SCR). In this study, we rationalize the origin of the beneficial effect of NO on the NO conversion by combining catalytic experiments with characterization and in X-ray absorption spectroscopy (XAS) and infrared spectroscopy in diffuse reflectance mode (DRIFTS) on a series of Fe-ZSM-5 catalysts where we attempted to control Fe speciation at constant Fe content. The catalytic activity data revealed that NO can promote NO conversion at different temperatures and to different extents.

Elucidation of site-specific red-ox kinetics in the CO-assisted NO decomposition over Fe-ferrierite by combining modulation excitation with EPR spectroscopy.

The catalytic conversion of NO over Fe-exchanged zeolites is an essential process for controlling its anthropogenic emissions and detrimental environmental impact. In the present study, we monitored an industrial Fe-ferrierite catalyst under conditions of CO-assisted decomposition of NO using electron paramagnetic resonance (EPR) spectroscopy within the modulated excitation (ME) paradigm. Exploiting this approach, we demonstrated that NO decomposition occurs reversible Fe/Fe transitions localized exclusively on isolated Fe centers located in the β-cationic position, successfully distinguished among various spectator species.

Leading through gaze: Enhanced social attention in high-rank members of a large-scale organization.

Human attention is naturally directed where others are looking. Primate research indicates that this phenomenon is influenced by the social rank of the gazer. Whether this applies to human societies remains underexplored.
