Sensitivity of inhalation anesthetics isoflurane and sevoflurane for the drug-induced QT-interval prolongation in guinea pigs

Journal of Pharmacological Sciences, 2020
We investigated effects of isoflurane and sevoflurane on sparfloxacin-induced QT-interval prolongation in guinea pigs under the monitoring of electrocardiogram and monophasic action potential (MAP), which was compared with those of halothane or non ...

Effect of Hydroxychloroquine and Azithromycin on QT Interval Prolongation and Other Cardiac Arrhythmias in COVID-19 Confirmed Patients

Cardiovascular Therapeutics, 2021
Background. Hydroxychloroquine with or without azithromycin was one of the common therapies at the beginning of the COVID-19 pandemic. They can prolong QT interval, cause torsade de pointes, and lead to sudden cardiac death.

Epicardial adipose tissue predicted prolonged QTc interval in patients with arterial hypertension

Clinical and Experimental Hypertension, 2021
Introduction: It is important to identify those at higher risk for ventricular arrhythmia among hypertensive patients. Epicardial adipose tissue (EAT) leads to electromechanical changes in the heart by endocrine and paracrine effects with cytokines and ...

Photoactivated Proximity Protein Labeling Reveals Enhanced Tumor Retention of a D‐Peptide‐Ruthenium Prodrug Conjugate

Advanced Healthcare Materials, EarlyView.
Six stereoisomeric ruthenium‐peptide conjugates were synthesized and characterized, which showed high potential in photoactivated chemotherapy (PACT) and proximity protein labeling. Abstract Amino acid chirality is known to influence the biological properties of peptide‐containing prodrugs.

Multimodal Luminescence from LaAlO3:Eu3+ via Trap Modulation for High‐Temperature Applications

Advanced Photonics Research, EarlyView.
LaAlO3:Eu3+ (LAO:E) phosphor exhibiting multimode luminescence enabled by multilevel traps spanning shallow to deep states is reported. These traps ensure controlled charge storage and release at room and elevated temperatures. Experimental studies and theoretical calculations reveal the trapping–detrapping mechanism, highlighting LAO:E as a promising ...
