Left ventricular systolic function evaluated by strain echocardiography and relationship with mortality in patients with severe sepsis or septic shock. a systematic review and meta-analysis [PDF]

open access: yes, 2018
Sepsis-induced myocardial dysfunction is associated with poor outcomes, but traditional measurements of systolic function such as left ventricular ejection fraction (LVEF) do not directly correlate with prognosis.

Computational Analysis of a GST‐Based Long‐Wave Infrared Microring Resonator on a ZnSe Platform as a Photonic Sensor

open access: yesAdvanced Photonics Research, EarlyView.
A Ge2Sb2Te5 (GST)‐based microring resonator is designed and simulated on a ZnSe‐platform that operates in the long‐wave infrared (LWIR) wavelength of 8 μm. The structure demonstrates strong power confinement and high Q‐factor. GST resonator is used for gas and biosensing applications.

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

open access: yesAdvanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

F‐Box and Leucine‐Rich Repeat Protein 4 (FBXL4) Maintains Sarcomere Integrity and Cardiac Function by Enhancing K48‐Linked Ubiquitinated Degradation of Profilin‐1 (PFN1)

open access: yesAdvanced Science, EarlyView.
Schematic diagram depicting the proposed signaling mechanisms underlying the effects of FBXL4 in the setting of cardiac hypertrophy. Under hypertrophic stimulation, cardiomyocytes‐specific overexpression FBXL4 maintains sarcomere integrity and cardiac function by enhancing K48‐linked ubiquitinated degradation of PFN1 at the K70 site.
