Advanced Science, EarlyView.A covalently integrated single‐component photocatalyst is constructed by anchoring selenoviologen to platinum nanoparticles via robust N‐heterocyclic carbene ligands. The resulting Pt─C covalent bonds function dually as protective structural scaffolds and direct channels for ultrafast intramolecular electron transfer This precise interfacial ...

Metal‐Half‐Salen Chemistry for One‐Pot Mineralization on Hydrophobic Polymer Membranes
Advanced Science, EarlyView.Here we report a versatile one‐pot synthetic strategy for organic–inorganic composite membranes, which leverages a metal half‐Salen system to precisely govern the competing kinetics of coordination and hydrolysis. In contrast to conventional two‐step metal‐phenol chemistries, our integrated approach substantially simplifies the fabrication process ...

The Association of QT Dispersion and QT Dispersion Ratio with Extent and Severity of Coronary Artery Disease [PDF]
Annals of Noninvasive Electrocardiology, 2006 Background: Although prolongation of the QT intervals in acute ischemic conditions, such as acute myocardial infarction, intracoronary balloon inflation, and exercise induced ischemia, has been shown, association of rest QT intervals with extent and severity of stable coronary artery disease (CAD) has not been assessed so far.

Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]
, 2005 The dependence on heart rate of the QT interval has been investigated for many years and several mathematical formulae have been proposed to describe the QT interval/heart rate (or QT interval/RR interval) relationship. While the most popular is Bazett’s

Advanced Science, EarlyView.A high‐entropy strategy is developed to break the trade‐off between low melting point and high ionic conductivity in molten salt electrolytes. By incorporating CsBr and LiF into the LiCl‐LiBr‐KBr system, the quinary LiF‐LiCl‐LiBr‐KBr‐CsBr electrolyte achieves a record‐low melting point of 229.5°C while maintaining a high conductivity of 1.19 S cm−1 at ...

Advanced Science, EarlyView.A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

QT dispersion in the electrocardiogram in hemodialysis and peritoneal dialysis patients
Saudi Journal of Kidney Diseases and Transplantation, 2014 To evaluate QT dispersion (QTd) in dialysis patients in an analytic cross-sectional study, three groups were enrolled: Hemodialysis (HD), peritoneal dialysis (PD) and control (30 patients in each group) to study QT parameters in 12-lead ...

The Effect of Sleep Apnea on QT Interval, QT Dispersion, and Arrhythmias [PDF]
Clinical Cardiology, 2010 AbstractBackgroundQT interval (QT) and QT dispersion (QTd) are electrocardiograph (ECG) parameters for the evaluation of myocardial repolarization. The inhomogeneity of ventricular repolarization is associated with ventricular arrhythmias. An increased QT, QTd, and increased incidence of nocturnal cardiac rhythm disturbances have been described in ...
