Modifying Glucose Metabolism Reverses Memory Defects of Alzheimer's Disease Model at Late Stages

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Using spatial transcriptomics, we show that ferul enanthate (SL‐ZF‐01) reverses episodic‐like memory deficits in aged, but not young, Alzheimer’s disease (AD) mice. SL restores glucose metabolism and Glucose Transporter 1/3 expression via an ‘Aging‐AD‐Rescue’ pattern, rescuing deficits seen in aged AD mice.

Cerebrovascular Accident Caused by Embolic Atrial Myxoma [PDF]

, 2013
Background: Atrial myxomas, the most common type of cardiac tumors, can cause life-threatening complications. As most cardiac myxomas are surgically curable, early diagnosis is crucial. Cardiac tumors can present with cardiac and embolic manifestations,

EAM‐CT Merge Guiding a Safe Transeptal Puncture in Atrial Tachycardia Ablation in a Intracardiac Fontan Patient

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT A patient with tricuspid valve atresia and pulmonary artery valve stenosis underwent a total cavo‐pulmonary circulation with an unfenestrated intracardiac conduit. He experienced poorly tolerated atrial tachycardia and was referred for radiofrequency catheter ablation (RFCA). No interatrial shunt was evident.

A simple voltage/mass index increases the suspicion of amyloidotic cardiomyopathy: an electrocardiographic and echocardiographic study of 767 patients with increased left ventricular wall thickness due to different causes [PDF]

, 2015
Background-Amyloidotic cardiomyopathy (AC) can mimic true left ventricular hypertrophy (LVH), including hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD).

Right Atrial Myxoma Presenting as Fever of Unknown Origin: A Rare Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
A young male from a tropical region presented with prolonged high‐grade fever unresponsive to antimicrobial therapy. Negative infectious workup prompted evaluation for fever of unknown origin. Early echocardiography revealed a right atrial myxoma. Myxoma‐related cytokine release contributed to fever and surgical resection led to complete clinical ...

Effects of Acute Autonomic Modulation on Atrial Conduction Delay and Local Electrograms Duration in Paroxysmal Atrial Fibrillation [PDF]

, 2011
Slowed atrial conduction may contribute to reentry circuits and vulnerability for atrial fibrillation (AF). The autonomic nervous system (ANS) has modulating effects on electrophysiological properties.

Fetal Diagnosis of Hypoplastic Left Heart Syndrome With Restrictive Atrial Septum—Atrial Septal Morphology, Associated Lung Disease and Outcomes

Prenatal Diagnosis, Volume 46, Issue 2, Page 183-192, February 2026.
ABSTRACT Objective Fetuses with hypoplastic left heart syndrome (HLHS) and restrictive/intact atrial septum (RAS) have high mortality, partly due to pulmonary lymphangiectasia (PL). This study aimed to characterize atrial septal morphology in fetuses with HLHS and RAS and evaluate the impact of fetal intervention on PL and outcomes.

P3799Experimental model of interatrial block by Bachmann bundle conduction block

European Heart Journal, 2019
Abstract Background The recognition of advanced IAB is becoming an important clinical landmark due to its association with atrial fibrillation, the so-called Bayes' syndrome. The electrocardiographic (ECG) criteria of interatrial block (IAB) have been established.

Atrial detection and timing for atrioventricular synchronous pacing [PDF]

, 2013
Dual chamber pacing can be employed to restore atrioventricular synchrony in patients with heart block; and chronotropic incompetence and sinus bradycardia in those with sinus node dysfunction (SND).
