14‐3‐3γ Protects Against Postoperative Cognitive Dysfunction by Regulating Tau Thr205 Phosphorylation and Synaptic Integrity

open access: yesAdvanced Science, EarlyView.
Integrative multi‐cohort analyses identify 14‐3‐3γ as a biomarker and regulator of cognitive vulnerability. Experimental studies show that 14‐3‐3γ loss is associated with Tau Thr205 phosphorylation, synaptic dysfunction, and cognitive impairment, while genetic overexpression or pharmacological stabilization of 14‐3‐3γ confers protective effects in ...

Ablative Management of Persistent Atrial Fibrillation (PeAF) with Posterior Wall Isolation (PWI): Where Do We Stand?

open access: yesJournal of Cardiovascular Development and Disease, 2023
Atrial fibrillation is a diverse clinical entity, with persistent atrial fibrillation (PeAF) being particularly challenging to manage. Through this paper, we discuss notable developments in our understanding of ablative strategies for managing PeAF, with

Catheter ablation of persistent and long-standing persistent atrial fibrillation. Strategies and results [PDF]

open access: yes, 2013
Catheter ablation for paroxysmal atrial fibrillation is a meanwhile established therapy option, which is most frequently performed using radiofrequency ablation. Mid-term success rate of 70 % are achievable with a single ablation procedure.

Proteogenomic Profiling of Idiopathic Pulmonary Arterial Hypertension Identifies Sex‐Differential Proteins and Candidate Therapeutic Targets

open access: yesAdvanced Science, EarlyView.
An integrated proteogenomic analysis of 44,137 predominantly European‐ancestry UK Biobank participants aged 40–69 years identifies 12 robust proteins associated with idiopathic pulmonary arterial hypertension. These proteins define a high‐mortality molecular endotype, support early detection and mortality prediction, reveal sex‐differential proteomic ...

The Deubiquitinase UCHL1 Drives Susceptibility to Atrial Fibrillation by Stabilizing CaMKII‐δ

open access: yesAdvanced Science, EarlyView.
UCHL1 is highly upregulated in mice and patients with AF. UCHL1 directly binds to and removes K48‐linked polyubiquitin chains from CaMKII‐δ at K251 and enhances CaMKII‐δ stability, which activates RyR2, disrupts Ca2+ handling, and promotes AF. These findings establish UCHL1 as a critical regulator of CaMKII‐δ stability and AF‐related Ca2+ handling ...

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

open access: yesAdvanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

The G protein-gated potassium current I(K,ACh) is constitutively active in patients with chronic atrial fibrillation [PDF]

open access: yes, 2005
Background— The molecular mechanism of increased background inward rectifier current (IK1) in atrial fibrillation (AF) is not fully understood. We tested whether constitutively active acetylcholine (ACh)-activated IK,ACh contributes to enhanced basal ...

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

open access: yesAGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...
