Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

High‐Temperature Persistent Luminescence and Anti‐Thermal Quenching in LiGa5O8 by Trap Engineering

Advanced Science, EarlyView.
Cu/Zn co‐doping creates deep and thermally stable traps in LiGa5O8, enabling enhanced high‐temperature persistent luminescence, anti‐thermal‐quenching emission, and dynamic blue‐to‐red color evolution. ABSTRACT High‐temperature luminescent materials are essential for applications in displays, information storage, anti‐counterfeiting, and extreme ...

Efek Resusitasi Jantung Paru Menggunakan Mechanical Chest Compressions Terhadap Keselamatan Pasien Henti Jantung

, 2020
Background: Cardiac arrest is the biggest cause of death. The number of patients who survived is low. Data in the UK shows only 7% of patients who survived. The key factor to increase the amount of survival is the quality of cadiopulmonary resuscitation (

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Mechanical versus manual chest compressions in the treatment of in-hospital cardiac arrest patients in a non-shockable rhythm: a randomised controlled feasibility trial (COMPRESS-RCT)

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2018
Background Mechanical chest compression devices consistently deliver high-quality chest compressions. Small very low-quality studies suggest mechanical devices may be effective as an alternative to manual chest compressions in the treatment of adult in ...

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...
