Initiation Kinetics of Latent Olefin Metathesis Precatalysts

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Ready, set, go: Initiation of several latent olefin metathesis precatalysts was measured both by light and heat activation. Sulfur‐chelated ruthenium precatalysts were initiated more efficiently when thermally activated, while the precatalysts with phosphite ligands were more responsive to photochemical stimulation. The initiation results were compared

Facile synthesis of two-photon absorbing polymers through radical copolymerization

open access: yeseXPRESS Polymer Letters, 2007
A two-photon absorbing polymer has been prepared through radical copolymerization of methyl acrylate and a synthesized monomer containing a two-photon absorbing chromophore (E,E,E)-1,3,5-tristyrylbenzene (1), under conventional radical polymerization ...

T Cell Glycoengineering to Modulate Immune‐Tumor Crosstalk: A Universal Non‐Genetic Strategy for Enhanced Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study describes a T cell surface engineering strategy that integrates polymer materials with tumor immunology, aiming to achieve broad‐spectrum anti‐tumor applications of glycopolymer‐engineered T (G‐T) cells via non‐genetic modification. Glycopolymer engineering generally modulates immune‐tumor crosstalk through specific cell‐cell interactions ...

Cyclic polyesters prepared by poly(oxypropylene oxymaloyl) ring-chain reactions

open access: yeseXPRESS Polymer Letters, 2007
The synthesis of cyclic polyesters of poly(oxypropylene oxymaloyl) from a ring-chain reaction was carried out at 40°C with 'Maghnite' an acid exchanged montmorillonite as acid solid ecocatalyst (Mag–H+).

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental
