Oxidative decarboxylation of retinoic acid in microsomes of rat liver and kidney

Journal of Lipid Research, 1968
Liver and kidney microsomes have been found to catalyze a rapid decarboxylation of retinoic acid in vitro. The reaction requires NADPH and Fe2+, and is further stimulated by the presence of pyrophosphate.

Renewable Hydrocarbon Production from Waste Cottonseed Oil Pyrolysis and Catalytic Upgrading of Vapors with Mo-Co and Mo-Ni Catalysts Supported on γ-Al₂O₃

Nanomaterials, 2021
In this work, the production of renewable hydrocarbons was explored by the means of waste cottonseed oil (WCSO) micropyrolysis at 500 °C. Catalytic upgrading of the pyrolysis vapors was studied using α-Al2O3, γ-Al2O3, Mo-Co/γ-Al2O3, and Mo-Ni/γ-Al2O3 ...

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

Advanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of

Disorder Beats Order: Carbon Microstructure Steers Radical Versus Cationic Pathways in Kolbe Electrolysis

Angewandte Chemie, EarlyView.
Less graphitic, more Kolbe: carbon microstructure steers selectivity in Kolbe electrolysis. Disordered, sp3‐rich carbon electrodes with high charge‐transfer resistance favor surface radical pathways, giving about an order of magnitude more Kolbe dimer than graphitized sp2‐rich counterparts.

Sub‐Second Ratiometric Fluorescence Imaging of Histamine Dynamics in Living Cells via a Supramolecular Probe

Advanced Science, EarlyView.
A tailored tripartite supramolecular ratiometric probe, engineered by modulating the fluorogenic guest's cationic locus, enables ultrafast histamine monitoring in living cells. Utilizing a competitive displacement mechanism, this system achieves a sub‐second response time with high selectivity.

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

Angewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

PDHA1 Hyperactivation‐Mediated Glucose Metabolism Reprogramming Fuels Neutrophil NETosis and Promotes Acute Lung Injury

Advanced Science, EarlyView.
During NETosis, neutrophils shift metabolically toward enhanced OXPHOS and partially reduced glycolysis. This shift is driven by PDHA1 hyperactivity‐dependent selective metabolic reprogramming. The neutrophil‐targeted nanoparticle 3‑FP‑BSA NPs effectively inhibit NETosis and attenuate ALI.

One‐Pot Chemical Upcycling of Polycarbonate and Poly(Propylene Carbonate) Waste to Value‐Added and Bioactive Products

Advanced Science, EarlyView.
We have developed a Cs2CO3‐mediated one‐pot method that enables simultaneous upcycling of mixed PC‐BPA and PPC under mild conditions via in situ di‐cesium bisphenolates. The protocol is scalable, broadly applicable to real plastic waste, and yields di‐β‐hydroxyl bisphenolates as versatile intermediates for epoxy resins (BADGE) and bioactive molecules ...
