    Class 3 PI3K coactivates the circadian clock to promote rhythmic de novo purine synthesis

    Metabolic demands fluctuate rhythmically and rely on coordination between the circadian clock and nutrient-sensing signalling pathways, yet mechanisms of their interaction remain not fully understood. Surprisi...

    Phenomena at three-phase electroslag remelting

    The electroslag remelting (ESR) process is widely used to produce high-quality ingots and billets for high-alloyed steels and alloys. Both the single-phase and three-phase alternating current diagram with bifi...

    Circadian Lipidomics: Analysis of Lipid Metabolites Around the Clock

    Lipidomics has been defined as the large-scale analysis of lipids in organelles, cells, tissues, or whole organisms. Including the temporal aspects of lipid metabolic changes into this analysis allows to acces...

    MicroRNAs modulate core-clock gene expression in pancreatic islets during early postnatal life in rats

    Evidence continues to emerge detailing a fine-tuning of the regulation of metabolic processes and energy homeostasis by cell-autonomous circadian clocks. Pancreatic beta cell functional maturation occurs after...

    Comparison of ARC Slag Remelting vs. P-ESR Melting for High Nitrogen Steels

    High Nitrogen Steels with nitrogen contents above atmospheric solubility are usually melted using an advanced P-ESR process under elevated pressure. The nitrogen pick up can be controlled by Si3N4 or nitrogen gas...
