Defect‐Functionalization‐Mediated Tunneling Drives Nonlinear Photoemission in Perovskites

Advanced Science, EarlyView.
This cover illustration depicts CsPbBr3 perovskite nanocrystals embedded with functionalized defect vacancies, where electrons migrate through defect‐mediated pathways and emit as lightning‐like beams. The imagery visualizes the core discovery of our work—defect‐functionalization‐mediated tunneling enabling nonlinear photoemission, where deep‐level ...

Particularities of rhythm and conduction disorders in heart failure patients with preserved ejection fraction admitted to a rehabilitation hospital [PDF]

Balneo and PRM Research Journal
(1) Background: The mortality and prognosis of patients with heart failure with preserved ejection fraction have shown minimal improvement over the past 20 years, possibly since this condition is often accompanied by various other cardiovascular risk ...

The year in cardiology: heart failure 2014 [PDF]

, 2017
The year 2014 has become a remarkable year for heart failure. A bad start was caused by the publication of TOPCAT, showing that spironolactone did not prove to be beneficial for the treatment of patients with heart failure and preserved ejection fraction

Heart rate response and functional capacity in patients with chronic heart failure with preserved ejection fraction [PDF]

, 2018
Aims: The mechanisms of exercise intolerance in heart failure with preserved ejection fraction (HFpEF) are not yet elucidated. Chronotropic incompetence has emerged as a potential mechanism.

Biomimetic Bone Marrow Monocyte Membrane‐Fused Extracellular Vesicles for Targeted Therapy of Myocardial Infarction

Advanced Science, EarlyView.
This study develops a biomimetic delivery system (M‐hEV) by fusing monocyte membranes with extracellular vesicles for targeted therapy of damaged cardiac tissue. The system homes to injured myocardium through specific molecular pathways. In a myocardial infarction model, M‐hEV effectively accumulates in the heart, reduces infarct size, alleviates ...

Early Outcomes After Total Arch Replacement With Frozen Elephant Trunk in Elderly Patients With Acute Type A Aortic Dissection

AGING MEDICINE, EarlyView.
Across seven centers (2015–2023), we studied 1634 ATAAD patients undergoing TAR+FET and, after propensity matching (n = 699), compared elderly (≥ 60) versus non‐elderly (< 60) outcomes. Elderly patients had higher 30‐day mortality and complications (log‐rank p = 0.002), supporting individualized hybrid strategies, organ‐protective perioperative care ...

Interleukin-1 blockade in heart failure with preserved ejection fraction: rationale and design of the Diastolic Heart Failure Anakinra Response Trial 2 (D-HART2) [PDF]

, 2017
Heart failure with preserved ejection fraction (HFpEF) now accounts for the majority of con-firmed HF cases in the United States. However, there are no highly effective evidence-basedtreatments currently available for these patients.

Autonomous Machine Learning‐Based Classification and Arrangement of Submillimeter Objects Using a Capillary Force Gripper

Advanced Intelligent Discovery, EarlyView.
This study presents an automated system integrating a capillary force gripper and machine learning‐based object detection for sorting and placing submillimeter objects. The system achieved stable and simultaneous manipulation of four object types, with an average task time of 86.0 seconds and a positioning error of 157 ± 84 µm, highlighting its ...

Axial Muscle Size as a Strong Predictor of Death in Subjects With and Without Heart Failure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background The impact of skeletal muscle size, quantified using simple noninvasive images routinely obtained during cardiac magnetic resonance imaging studies on mortality in the heart failure (HF) population is currently unknown.
