Lipophilicity and blood partitioning are important determinants for predicting toxicokinetics using physiologically-based toxicokinetic (PBTK) modeling. In this study, the logarithm of the -octanol:water partition coefficient (log) and the blood-to-plasma concentration ratio ( ) were for the first time experimentally determined for the pyrrolizidine alkaloids (PAs) intermedine, lasiocarpine, monocrotaline, retrorsine and their -oxides (PANOs). Validated assays for log (miniaturized shake-flask method) and (LC-MS/MS-based depletion assay) determination were compared to an ensemble of models.

Fluorine-free organic framework polyelectrolyte membranes showing near frictionless ionic conductivities are gaining cognitive insights. However, the co-precipitation of COFs in the membranes often brings trade-offs to commission long-life electrochemical energy storage solutions. Herein, a durable and ionically miscible dual-ion exchange membrane based on triazine organic framework (TOF) is designed for alkaline redox flow batteries (RFB).

Ethylene glycol (C₂H₆O₂), a toxic alcohol commonly found in automotive antifreeze, de-icing solutions, and industrial coolants, can cause severe toxicity when ingested. Due to its sweet taste, it is often consumed accidentally or intentionally, leading to life-threatening consequences such as metabolic acidosis, acute kidney injury (AKI), and mortality. Prompt diagnosis and early treatment with antidotes such as fomepizole or ethanol, combined with hemodialysis, are essential in preventing severe outcomes.

The endoplasmic reticulum (ER) is a vital organelle responsible for protein quality control, including the folding, modification, and transport of proteins. When misfolded or unfolded proteins accumulate in the ER, it triggers endoplasmic reticulum stress (ERS) and activates the unfolded protein response (UPR) to restore ER homeostasis. However, prolonged or excessive ERS can lead to apoptosis.

In nuclear wastewater treatment, ion-scavenging materials designed to trap TcO is urgently needed. However, strong acid/base, high radiation and high salt concentration of nuclear wastewater usually result in inadequate stability and adsorption capacity of the adsorbent. Herein, we report a new class of bifunctional anion-exchange olefin-linked COF (BPDC-MTMP) prepared via Knoevenagel condensation reactions, the first example exploring the synergistic integration of positively charged fragments at both nodes and linkers.
