Force stimulation promotes nerve regeneration by restoring cellular energy

BMEMat, EarlyView.
Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

In vitro ultrastructure and biodegradation of activated plasma albumin gel derived from human samples: A prospective observational study

Clinical Advances in Periodontics, EarlyView.
Abstract Background In soft tissue regeneration, the clinical efficacy of fibrin membranes has been a pressing concern. The key to this efficacy lies in the stability of membrane and its controlled absorption. Human serum albumin, with its influence on the formation and stability of fibrin networks, could hold the key to developing a more stable ...

Initial rotor position estimation method for aircraft wound‐rotor synchronous starter/generators

The Journal of Engineering, 2018
An initial rotor position estimation method which is independent of the magnetic saliency is proposed for the main generator (MG) of aircraft three‐stage wound‐rotor synchronous starter/generators. Voltage signals are injected into the stator of the MG and the field current response of the MG is evaluated in this method.

Antidiabetic Potential of Ligands from NEIST_PMIB_06, Bacterium Associated with Hawaijar (Fermented Soy Food): Insight from in Vitro and in Silico Studies

ChemFoodChem, EarlyView.
ABSTRACT In this study, a bacterium (NEIST_PMIB_06) was isolated from Hawaijar, a fermented soy food from Manipur, Northeast India. The bacterium was inoculated and incubated to isolate bioactive compounds. Liquid‐liquid extraction was performed to obtain extracts (cell‐free and cell‐based), and their efficacy was evaluated.
