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 ...

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.

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 ...

Does the use of a chest compression system in children improve the effectiveness of chest compressions? A randomised crossover simulation pilot study.

Kardiologia polska, 2016
BACKGROUND Providing high-quality chest compressions is a key element affecting the effectiveness of cardiopulmonary resuscitation (CPR). AIM To evaluate the effectiveness of standard (manual) chest compressions (Standard BLS, standard basic life ...

Performance of the Bebé VieScope Versus Direct Laryngoscopy During Pediatric Cardiopulmonary Resuscitation: A Prospective Randomized Simulation Study

Children
Background/Objectives: Effective airway management during pediatric cardiopulmonary resuscitation (CPR) is crucial but technically challenging, especially during continuous chest compressions. While direct laryngoscopy with Macintosh (MAC) or Miller (MIL)

Improved recognition of ineffective chest compressions after a brief Crew Resource Management (CRM) training: a prospective, randomised simulation study

BMC Emergency Medicine, 2016
BackgroundChest compressions are a core element of cardio-pulmonary resuscitation. Despite periodic training, real-life chest compressions have been reported to be overly shallow and/or fast, very likely affecting patient outcomes.

Comparison of the quality of chest compressions on a dressed versus an undressed manikin: A controlled, randomised, cross-over simulation study

Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, 2010
Background Undressing the chest of a cardiac arrest victim may delay the initiation of chest compressions. Furthermore, expecting laypeople to undress the chest may increase bystander reluctance to perform cardiopulmonary resuscitation (CPR).
