Identification of a hippocampal lncRNA-regulating network in cognitive dysfunction caused by chronic cerebral hypoperfusion.

Cognitive dysfunction caused by chronic cerebral hypoperfusion is a common underlying cause of many cognition-related neurodegenerative diseases. The mechanisms of cognitive dysfunction caused by CCH are not clear. Long non-coding RNA is involved in synaptic plasticity and cognitive function, but whether lncRNA is involved in cognitive dysfunction caused by CCH has not yet been reported.

Identification and Validation Novel of VIM-2 Metallo-β-lactamase Tripeptide Inhibitors.

The development of novel inhibitors against metallo-β-lactamase is essential to remedy metallo-β-lactamase mediated bacterial resistance. A recently emerged metallo-β-lactamase, VIM-2, has demonstrated resistance to existing β-lactamase inhibitors in the clinic. In this study, a hybrid virtual screening protocol that combines pharmacophore modeling, molecular docking, and calculation of binding free energy was employed to screen an internal tripeptide database for novel inhibitors against VIM-2.
