Multifunctional Tailoring of Fertilizer Composites Directly Derived From Phosphate Rock

open access: yesAdvanced Science, EarlyView.
A novel phosphorus‑sulfur mixed acid with urea (PSU) activation system converts low‑grade phosphate rock (LPR) into multifunctional fertilizer composites (MFCs). MFCs feature porous structures, high nutrient‑activation efficiency, superior slow‑release, and enhanced crop growth, offering a sustainable solution for integrated nutrient management and ...

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

open access: yesAdvanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

QT Interval Revisited —Not Just the Matter of “Interval,” but “Dynamics, Variability and Morphology” Matter!—

open access: yesJournal of Arrhythmia, 2007
Recently, the effects of QT interval prolongation have received more attention among clinicians, industry, and official regulatory agencies. Some have advocated the total elimination or discontinuing development of drugs which prolong the QT interval. In

Microglial GPR35 Ameliorates Epileptogenesis and Neuroinflammation via PDGFA Domain 2 Signaling

open access: yesAdvanced Science, EarlyView.
Activation of microglial G protein–coupled receptor 35 (GPR35) by L‐kynurenic acid (L‐Kyna) initiates a platelet‐derived growth factor A (PDGFA)–dependent phosphoinositide 3‐kinase–protein kinase B (PI3K–AKT) signaling cascade that dampens hippocampal neuroinflammation, thereby restraining epileptogenesis, lowering seizure susceptibility, and ...

Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]

open access: yes, 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
