Defective blue titanium oxide induces high valence of NiFe-(oxy)hydroxides over heterogeneous interfaces towards high OER catalytic activity.

Nickel-iron (oxy)hydroxides (NiFeOH) have been validated to speed up sluggish kinetics of the oxygen evolution reaction (OER) but still lack satisfactory substrates to support them. Here, non-stoichiometric blue titanium oxide (B-TiO) was directly derived from Ti metal by alkaline anodization and used as a substrate for electrodeposition of amorphous NiFeOH (NiFe/B-TiO). The performed X-ray absorption spectroscopy (XAS) and density functional theory (DFT) calculations evidenced that there is a charge transfer between B-TiO and NiFeOH, which gives rise to an elevated valence at the Ni sites (average oxidation state ∼ 2.

Volatile Versus Total Intravenous Anesthesia on Postoperative Delirium in Adult Patients Undergoing Cardiac Valve Surgery: A Randomized Clinical Trial.

Background: The effect of anesthesia regimens on postoperative delirium after on-pump cardiac valve surgery is yet undetermined. This study aimed to evaluate the effect of volatile anesthesia compared with propofol-based total intravenous anesthesia (TIVA) on the occurrence of delirium after on-pump cardiac valve surgery.

Methods: This randomized clinical trial was conducted at a university academic hospital in China, from February 2019 to January 2021.

Effect of Volatile Anesthesia Versus Total Intravenous Anesthesia on Postoperative Pulmonary Complications in Patients Undergoing Cardiac Surgery: A Randomized Clinical Trial.

Objectives: The purpose of this study was to evaluate the effect of volatile anesthesia and propofol-based total intravenous anesthesia (TIVA) on postoperative pulmonary complications (PPCs) among patients undergoing cardiac surgery.

Design: Parallel-group, randomized controlled trial.

Setting: Single-center tertiary care hospital.

polysaccharides inhibit ischemia/reperfusion-induced myocardial injury via the Nrf2 antioxidant pathway.

Oxidative stress is considered to be one of main pathophysiological mechanisms in myocardial ischemia/reperfusion (I/R) injury. polysaccharides (LBP), the main ingredient of , have potential antioxidant activity. We aimed to investigate the effects of LBP on myocardial I/R injury and explore the underlying mechanisms.

The Effect of Propofol Versus Volatile Anesthetics on Persistent Pain After Cardiac Surgery: A Randomized Controlled Trial.

Objectives: Sternal incisions can generate persistent and intense post-sternotomy pain. Propofol has been shown to improve postoperative analgesia, but the preventive effect on persistent pain after cardiac surgery is unknown. The hypothesis of the present study was that intraoperative propofol-based anesthesia compared with volatile anesthesia could reduce the risk of chronic pain after cardiac surgery.

Comparison of low and high inspiratory oxygen fraction added to lung-protective ventilation on postoperative pulmonary complications after abdominal surgery: A randomized controlled trial.

Study Objective: Intraoperative lung-protective ventilation strategy has been recommended to reduce postoperative pulmonary complications (PPCs). However, the role of inspiratory oxygen fraction (FiO) in this protection remains highly uncertain. We aimed to evaluate the effect of intraoperative low (30%) versus high (80%) FiO in the context of lung-protective ventilation strategy on PPCs in patients undergoing abdominal surgery.

PROtective Ventilation with a low versus high Inspiratory Oxygen fraction (PROVIO) and its effects on postoperative pulmonary complications: protocol for a randomized controlled trial.

Background: Postoperative pulmonary complications (PPCs) are the most common perioperative complications following surgical site infection (SSI). They prolong the hospital stay and increase health care costs. A lung-protective ventilation strategy is considered better practice in abdominal surgery to prevent PPCs.
