The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Comprehensive effect of Al2O3 content and binary basicity on the enrichment mechanism of phosphates in quenched steelmaking slags

open access: yes工程科学学报, 2016
A comprehensive effect of Al2O3 content and binary basicity B on the enrichment behavior of phosphates in rapidly quenched CaO-SiO2-FeO-P2O5-Fe2O3-Al2O3 steelmaking slags was investigated through thermodynamic calculations and experimental determination.

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Effect of Basicity of Tundish Covering Flux on Metallurgy Quality of Ferrite Stainless Steel

open access: yesTeshugang, 2013
In accordance with inclusion defects occurred on cold rolled sheet of 430, 0C113R, 409 etc. ferrite stainless steels, the effect of basicity (1. 10 ~ 5. 98) of tundish covering flux on cleanliness of steel is studied, and the change of basicity, Al2O3and

Thermodynamic analysis of the relationship between refining slag composition and inclusion type in bearing steel

open access: yes工程科学学报, 2016
In order to control large calcium aluminate inclusions in bearing steel, the quantitative relationship between refining slag composition and inclusion type is discussed by calculating the formation thermodynamics of MgO·Al2O3 and CaO·6Al2O3 in ...

Precipitated K-promoted Co-Mn-Al mixed oxides for direct NO decomposition: Preparation and properties [PDF]

open access: yes, 2019
Direct decomposition of nitric oxide (NO) proceeds over Co-Mn-Al mixed oxides promoted by potassium. In this study, answers to the following questions have been searched: Do the properties of the K-promoted Co-Mn-Al catalysts prepared by different ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

INFLUENCE OF THE RATIO OF CALCIUM OXIDE AND SILICA ON MINERALOGICAL AND PHASE CHANGES OF SINTER FROM LIMONITE ORE

open access: yesJournal of Sustainable Technologies and Materials
Improving the quality of iron ore sintering and adding specific components has positive effects on blast furnace productivity. Optimizing basicity in the blast furnace charge is one way to improve all indices of production processes.
