In Vitro Durability - Pivot bearing with Diamond Like Carbon for Ventricular Assist Devices [PDF]

arXiv, 2015
Institute Dante Pazzanese of Cardiology (IDPC) develops Ventricular Assist Devices (VAD) that can stabilize the hemodynamics of patients with severe heart failure before, during and/or after the medical practice; can be temporary or permanent. The ADV's centrifugal basically consist of a rotor suspended for system pivoting bearing; the PIVOT is the ...

Injectable and Sprayable Thermoresponsive Hydrogel with Fouling‐Resistance as an Effective Barrier to Prevent Postoperative Cardiac Adhesions

Advanced Science, EarlyView.
Postoperative cardiac adhesions lead to numerous difficulties in reoperation procedures. Here, a thermo‐responsive in situ formed hydrogel is shown to can reliably cover the wounds after a convenient spraying or injection and significantly reduce adhesion formation in primary and recurrent cardiac injury adhesion models.

Locus Coeruleus Noradrenergic‐Spinal Projections Contribute to Electroacupuncture‐Mediated Antinociception in Postoperative Pain in Mice

Advanced Science, EarlyView.
How locus coeruleus noradrenergic‐spinal projections and subsequent α2A adrenoceptors‐CaMKII signaling cascades contribute to electroacupuncture‐induced antinociception in postoperative pain in mice is described. Abstract Postoperative pain remains a significant challenge in healthcare.

Aortic Pressure Forecasting with Deep Sequence Learning [PDF]

arXiv, 2020
Mean aortic pressure (MAP) is a major determinant of perfusion in all organs systems. The ability to forecast MAP would enhance the ability of physicians to estimate prognosis of the patient and assist in early detection of hemodynamic instability. However, forecasting MAP is challenging because the blood pressure (BP) time series is noisy and can be ...
