Modulating Integrin and Growth Factor Signaling With Peptides: Strategies to Synergistically Enhance Bone Tissue Regeneration

Advanced Science, EarlyView.
It has been demonstrated that, in the bone extracellular matrix (ECM), integrins and growth factor receptors (GFRs) engage in synergistic signaling to guide bone healing and regeneration. This review provides a comprehensive overview of current strategies using ECM‐derived peptides to recreate the cellular microenvironment and harness synergistic ...

ASSOCIATION OF VERTEBRAL FRACTURES AND HIP FRACTURES IN PATIENTS WITH OSTEOPOROSIS

National Journal of Medical Research, 2014
Background: Osteoporosis is quite common disease among aged in India. Studies indicate that vertebral fractures are probably the most common fragility fractures and that they are often followed by a second fracture.

Transmission of Radio‐Frequency Waves and Nuclear Magnetic Resonance in Lanthanum Superhydrides

Advanced Science, EarlyView.
1H NMR and radio‐frequency transmission measurements of lanthanum superhydrides at 165 GPa reveals a transition at 260–280 K by a strong suppression of the signal intensity, significant changes in NMR spectra, including a dramatic decrease of the relaxation rate 1/T1T, and pronounced shielding effect, which may have a superconducting nature.

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

Advanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

Advanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...
