The power of microRNA regulation—insights into immunity and metabolism
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Determining an Efficient Solvent Extraction Parameters for Re-Refining of Waste Lubricating Oils [PDF]
Re-refining of vehicle waste lubricating oil by solvent extraction is one of the efficient and cheapest methods. Three extracting solvents MEK (Methyl-Ethyl-Ketone), 1-butanol, 2-propanol were determined experimentally for their performance based on ...

Comparison of Single-Ion Molecular Dynamics in Common Solvents [PDF]
Laying a basis for molecularly specific theory for the mobilities of ions in solutions of practical interest, we report a broad survey of velocity autocorrelation functions (VACFs) of Li$^+$ and PF$_6{}^-$ ions in water, ethylene carbonate, propylene carbonate, and acetonitrile solutions. We extract the memory function, $\gamma(t)$, which characterizes

Optimization of Anthocyanin Extraction from Saffron Petals with Response Surface Methodology [PDF]
Optimum extraction conditions of anthocyanins from petals of saffron (Crocus sativus) using acidified ethanol as the solvent were revealed. The investigated factors were solvent to sample ratio (20:1–80:1), ethanol concentration (%), extraction ...
