A minimal physiologically‐based pharmacokinetic modeling platform to predict intratumor exposure and receptor occupancy of an anti‐LAG‐3 monoclonal antibody

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 460-473, March 2025.
Abstract In oncology drug development, measuring drug concentrations at the tumor site and at the targeted receptor remains an ongoing challenge. Positron emission tomography (PET)‐imaging is a promising noninvasive method to quantify intratumor exposure of a radiolabeled drug (biodistribution data) and target saturation by treatment doses in vivo ...

Advances in research on layered double hydroxides for biomedical applications

Smart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Boron‐embedded multifunctional nanoplatform toward potential combined boron neutron capture therapy and immunomodulation in glioma

Smart Molecules, EarlyView.
A brain‐targeting multifunctional nanoplatform (DM&Ce6@COF‐Ang) was engineered by employing boron‐enriched APTES‐COF‐1 as both the therapeutic boron agent and the nanocarrier co‐delivery of DMXAA and Ce6. This nanoplatform achieved synergistic tumor‐specific boron delivery, real‐time pharmacokinetic monitoring, and immunomodulation.

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.
