Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

QT interval in healthy dogs: which method of correcting the QT interval in dogs is appropriate for use in small animal clinics?

Pesquisa Veterinária Brasileira, 2014
The electrocardiography (ECG) QT interval is influenced by fluctuations in heart rate (HR) what may lead to misinterpretation of its length. Considering that alterations in QT interval length reflect abnormalities of the ventricular repolarisation which ...

Early LQT2 Nonsense Mutation Generates N-Terminally Truncated hERG Channels with Altered Gating Properties by the Reinitiation of Translation

, 2012
Mutations in the human ether-a-go-go-related gene (hERG) result in long QT syndrome type 2 (LQT2). The hERG gene encodes a K+ channel that contributes to the repolarization of the cardiac action potential.

Clinical Pharmacogenetics Implementation Consortium (CPIC) Guideline for CYP2D6 Genotype and Use of 5‐HT3 Receptor Antagonists: 2026 Update

Clinical Pharmacology &Therapeutics, EarlyView.
5‐hydroxytryptamine type 3 (5‐HT3) receptor antagonists are used to treat nausea and vomiting and in the prevention of chemotherapy‐induced, radiation‐induced, and postoperative nausea and vomiting. Most of the 5‐HT3 receptor antagonists (i.e., ondansetron, tropisetron, dolasetron, palonosetron, and ramosetron) are metabolized by CYP2D6, but the extent

Effects of Neostigmine and Sugammadex for Reversal of Neuromuscular Blockade on QT Dispersion Under Propofol Anesthesia: A Randomized Controlled Trial

Cardiology and Therapy, 2018
Introduction Reversal of non-depolarizing neuromuscular blocking agent neostigmine is associated with QT prolongation under general anesthesia. To clarify the effects of neostigmine and sugammadex on hemodynamic status, the QT interval and QT dispersion ...

Cardiac remodeling and arrhythmia in a mouse model of Depdc5 haploinsufficiency

Epilepsia, EarlyView.
Abstract Objective Some ion channel genes linked to developmental and epileptic encephalopathy (DEE) are also linked to cardiac arrhythmia, leading to the hypothesis that predisposition to cardiac arrhythmias may contribute to the complex disease presentation of DEE and possibly to the mechanism of sudden unexpected death in epilepsy.

Altered circadian rhythmicity of the QT interval predicts mortality in a large real-world academic hospital population

Heliyon
Objective and rationale: Small studies have shown that the QT interval follows a circadian rhythm. This finding has never been confirmed in a large real-world hospital population and the clinical meaning of disrupted rhythmicity remains unknown. Methods:

Clinical cardiac electrophysiologic evaluation of the positive inotropic agent, DPI 201-106 [PDF]

, 2017
DPI 201-106 is a new positive inotropic agent. The cardiac electrophysiology of 16 patients was studied before and during DPI 201-106 administration (loading dose of intravenous DPI 201-106, 1·8 mg kg−1 h−1 administered over 10 min, followed by a ...
