FEBS Open Bio, EarlyView.Berberine–cinnamic acid co‐crystal (BBR‐CA) inhibits the phosphorylation of the phosphatidylinositol 3‐kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway, suppressing the transfer of pre‐sterol regulatory element‐binding proteins‐1 (SREBP‐1) from the endoplasmic reticulum to the nucleus. This results in a decrease in the expression level of

Revealing black holes with Gaia
, 2017 We estimate the population of black holes with luminous stellar companions (BH-LCs) in the Milky Way (MW) observable by Gaia. We evolve a realistic distribution of BH-LC progenitors from zero-age to the current epoch taking into account relevant physics,
