In silico approaches of gandarusa (Justicia gendarussa Burm. f.) potential for osteoporosis prevention via EGF pathway [PDF]

Journal of Pharmacy & Pharmacognosy Research
Context: On a cellular level, osteoporosis is a metabolic bone disease caused by osteoclastic bone resorption that is not offset by osteoblastic bone synthesis. This increases the risk of fractures by making bones weak and brittle.

Solid‐State ¹⁷O NMR Reveals Hydrogen‐Bonding Energetics: Not All Low‐Barrier Hydrogen Bonds Are Strong

Angewandte Chemie International Edition, 2017
AbstractWhile NMR and IR spectroscopic signatures and structural characteristics of low‐barrier hydrogen bond (LBHB) formation are well documented in the literature, direct measurement of the LBHB energy is difficult. Here, we show that solid‐state 17O NMR spectroscopy can provide unique information about the energy required to break a LBHB.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient
