Parameters of ventricular repolarization in patients with autoimmune hepatitis

Türk Kardiyoloji Derneği Arşivi, 2017
Objective: Autoimmune hepatitis (AIH) is a liver disorder that affects both children and adults. It is characterized by inflammatory liver histology, elevated transaminase level, circulating nonorgan-specific autoantibodies, and increased level of ...

Heritability of Tpeak-Tend interval and T-wave amplitude: a twin study [PDF]

, 2011
Background— Tpeak-Tend interval (TpTe) and T-wave amplitude (Tamp) carry diagnostic and prognostic information regarding cardiac morbidity and mortality. Heart rate and QT interval are known to be heritable traits.

The effects of peritoneal dialysis on QT interval in ESRD patients

BMC Nephrology, 2022
Background Patients with chronic kidney disease (CKD) are at a high risk of fatal arrhythmias. The extended corrected QT (QTc) interval is a hallmark of ventricular arrhythmias and sudden cardiac death.

Effect of QT interval-prolonging drugs taken in pregnancy on the neonatal QT interval

Frontiers in Pharmacology, 2023
Introduction: Acquired QT interval prolongations due to drug side effects can result in detrimental arrhythmia. Maternal use of placenta-permeable drugs may lead to fetal exposure, thus leading to an increased risk of neonatal QT prolongation and ...

Pharmacogenetics of Drug-Induced QT Interval Prolongation: An Update [PDF]

, 2015
A prolonged QT interval is an important risk factor for ventricular arrhythmias and sudden cardiac death. QT prolongation can be caused by drugs. There are multiple risk factors for drug-induced QT prolongation, including genetic variation.

Thoracic epidural analgesia prolongs postoperative QT interval on electrocardiogram in major non-cardiac surgery: a randomized comparison and a prospective cohort analysis

Frontiers in Pharmacology, 2023
Introduction: Prolongation of QT interval on electrocardiogram can be associated with perioperative lethal arrhythmia. Epidural analgesia is a commonly used modality to relieve surgical pain by blocking sensory nerves, which also blocks the autonomic ...

QT PRODACT: In Vivo QT Assay With a Conscious Monkey for Assessment of the Potential for Drug-Induced QT Interval Prolongation

Journal of Pharmacological Sciences, 2005
In safety pharmacology studies, the effects on the QT interval of electrocardiograms are routinely assessed using a telemetry system in cynomolgus monkeys. However, there is a lack of integrated databases concerning in vivo QT assays in conscious monkeys.

Trigger versus Substrate: Multi-Dimensional Modulation of QT-Prolongation Associated Arrhythmic Dynamics by a hERG Channel Activator [PDF]

, 2017
Background: Prolongation of the QT interval of the electrocardiogram (ECG), underlain by prolongation of the action potential duration (APD) at the cellular level, is linked to increased vulnerability to cardiac arrhythmia.

Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

Advanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.
