The futuristic manifolds of REM sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...

Pacemaker Arrhythmias and Electrocardiographic Recognition of Pacemakers

, 1973
Adequate interpretation of pacemaker arrhythmias requires a thorough knowledge of the clinical situation in which they appear, the type of pacemaker, and modality of stimulation used, as well as knowledge of the corresponding electronic specifications ...

Cardiac Implantable Electronic Device Infection: Nationwide Trends in Extraction Utilization and In‐Hospital Outcomes

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Introduction Contemporary, real‐world adherence to guideline‐directed transvenous cardiac implantable electronic device (CIED) extraction for patients with CIED infections in the US remains incompletely characterized. As such, we sought to evaluate national trends in CIED extraction and identify factors associated with extraction and in ...

Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Modeling experiments on pacemaker interactions in scyphomedusae [PDF]

, 2009
Scyphozoan jellyfish are free-swimming gelatinous organisms whose nervous system includes a motor nerve net that controls swimming. Swim contractions originate in a network of distributed pacemakers found in the marginal rhopalia, which are located ...

Novel volume‐electron microscopic ultrastructural analysis of gastrointestinal excitability associated with calcium–activated chloride channels

The Journal of Physiology, EarlyView.
Abstract figure legend Immunohistochemistry, electrophysiology and pharmacology are useful tools for understanding protein and channel expression and physiological reactions of calcium‐activated chloride channels (CaCCs). Conventional transmission electron microscopy has provided useful 2‐D information on organelle arrangement, localization and ...

TMEM16A Ca2+‐activated Cl− channel: Functional interactions with cytoskeletal and membrane‐associated proteins

The Journal of Physiology, EarlyView.
Abstract figure legend The calcium‐activated chloride (ClCa) channel TMEM16A (also known as ANO1) plays critical roles in ion transport, neurotransmission and smooth muscle contraction. Dysregulation of TMEM16A channel activity contributes to the development and progression of various diseases.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Comparison of Benefits from Cardiac Resynchronization Therapy between Patients with Ischemic Cardiomyopathy and Patients with Idiopathic Dilated Cardiomyopathy [PDF]

Journal of Tehran University Heart Center, 2009
Background: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with moderate to severe heart failure. However, 20-30% of patients remain non-responders to CRT.
