Temperature dependence of HCN channel kinetics: A systematic comparison across mammalian isoforms and species

open access: yesExperimental Physiology, EarlyView.
Abstract Hyperpolarization‐activated, cyclic nucleotide‐gated (HCN) channels are important regulators of cardiac pacemaking and neuronal excitability, yet their temperature dependence has not been compared systematically across mammalian isoforms and species in standardized experimental conditions. Here, we performed a standardized electrophysiological

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

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

open access: yesThe 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

open access: yesThe 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.

Removal of Transvenous Pacemaker Electrodes under Cardiopulmonary Bypass [PDF]

open access: yes, 1998
We report a patient in whom removal of transvenous pacemaker electrodes under cardiopulmonary bypass was successfully performed. The patient was a 75-year-old man who had undergone unsuccessful surgical treatments eight times followed by development of ...

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

open access: yesThe 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.

Cardiac Device Algorithms for Optimal Outcomes in Patients with Sick Sinus Syndrome [PDF]

open access: yes, 2013
Sick sinus syndrome (SSS) is a relatively common chronic condition affecting the electrical conduction system of the heart. In the absence of any reversible cause of SSS, the most effective treatment is implantation of a permanent pacemaker to maintain ...

Pancreatic Cancer Early Detection Biomarkers for High‐Risk Individuals: Insights From the PRECEDE Consortium

open access: yesInternational Journal of Cancer, Volume 159, Issue 8, Page 1873-1883, 15 October 2026.
ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers due to its asymptomatic progression, late‐stage diagnosis, and treatment resistance. Efforts in early detection have centered on identifying imaging features and liquid biopsy biomarkers capable of detecting PDAC and its high‐grade precursors before clinical symptoms ...

Survey of ST-Segment Changes due to Active Lead Fixation during Permanent Pacemaker Device Implantation as a Prognostic Indicator of its Performance

open access: yesمجله دانشکده پزشکی اصفهان, 2017
Background: Active lead implantation can create injury in myocardium that may be associated with a ST-segment elevation. This ST-segment elevation may be correlated with changes in other parameters such as threshold, sense, amplitude, impedance, and ...
