Adenylate-cyclase VI transforms ventricular cardiomyocytes into biological pacemaker cells

, 2010
When sinus node or atrioventricular (AV) node cells are damaged by disease, the implantation of an artificial cardiac pacemaker becomes necessary. In search for a biological alternative, the objective of this study was to demonstrate whether in vivo ...

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

مجله 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 ...

The Role of Neutrophils and NETosis in Diseases: The Implications for Therapy

MedComm, Volume 7, Issue 6, June 2026.
Neutrophils secrete cytokines, express specific surface proteins, increase or decrease in cell count, and their ratio to lymphocyte count can be used as biomarkers to characterize collective status and disease progression. Neutrophils can monitor and track the body's health status, “Wei Bing” status, disease status, and different times of disease ...

Quantitative T2* Magnetic Resonance Imaging for Iron Detection in Soft Tissue of the Fingers

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
T2* MRI was evaluated for detecting iron in soft tissues of the fingers. After visual inspection of dual‐colored maps, multiple regions of interest were placed in the soft tissues at areas that indicated increased susceptibility. Lower T2* values, indicative of iron deposition, were detected in patients with microvasculopathy (right panel) but not in ...

Membrane resonance in bursting pacemaker neurons of an oscillatory network is correlated with network frequency

, 2009
Network oscillations typically span a limited range of frequency. In pacemaker-driven networks, including many central pattern generators (CPGs), this frequency range is determined by the properties of bursting pacemaker neurons and their synaptic ...
