Enhanced Catalytic Cycle of Glucose Oxidation and Reactive Species with ROS and RHS Generation Mediated by Galvanic Engineering of Dual Atomic Sites on Covalent Organic Frameworks Demonstrating Synergistic Bimetal Tumor Treatment

open access: yesAdvanced Science, EarlyView.
A galvanic replacement is used to control dual atomic metals (Au and Ir) on a covalent organic framework (COF) nanoparticle and then coated with hyaluronic acid (HA). Under a specific bimetallic ratio (COF/Aux/Ir1‐x), the optimization can be achieved for the conversion of intracellular nutrients into reactive species (HOCl and O2• ─) and effectively ...

Conversion of Alcohols into Amides Using Alumina-Methanesulfonic Acid (AMA) in Nitrile Solvents [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 1999
The reaction of tertiary, secondary and benzylic alcohols with different nitriles in the presence of alumina-methanesulfonic acid (AMA) as a new reagent affords the corresponding amides in good yields (Table 1, 2).

Acrylamide Production Using Encapsulated Nitrile Hydratase from \u3cem\u3ePseudonocardia thermophila\u3c/em\u3e in a Sol–gel Matrix [PDF]

open access: yes, 2014
The cobalt-type nitrile hydratase from Pseudonocardia thermophila JCM 3095 (PtNHase) was successfully encapsulated in tetramethyl orthosilicate sol–gel matrices to produce a PtNHase:sol–gel biomaterial.

Dual Role of CRABP2 in Colorectal Cancer: Oncogenesis via Nuclear RB1 and Cytoplasmic AFG3L2/SLC25A39 Axis, While Limiting Liver Metastasis through Cytoplasmic AFG3L2/PINK1/Parkin‐Mediated Mitophagy

open access: yesAdvanced Science, EarlyView.
CRABP2 plays a dual role in colorectal cancer: it promotes proliferation and suppresses apoptosis through the nuclear CRABP2/RB1 axis and the cytoplasmic AFG3L2/SLC25A39 axis. Meanwhile, it inhibits colorectal liver metastasis via AFG3L2/PINK1/Parkin‐mediated mitophagy.

Wogonin Attenuates Atherosclerosis via KLF11‐Mediated Suppression of PPARα‐YAP1‐Driven Glycolysis and Enhancement of ABCA1/G1‐Mediated Cholesterol Efflux

open access: yesAdvanced Science, EarlyView.
PPARα promotes KLF11 expression and recruits KLF11 and YAP1 to form a transcription complex, where KLF11 acts as a brake in PPARα‐YAP1‐mediated glycolysis. Wogonin reshapes the metabolism of macrophages from glycolysis to fatty acid oxidation via activation of the PPARα‐KLF11‐YAP1 pathway, by which wogonin reduces inflammation and foam cell formation ...

The E3 Ubiquitin Ligase ARIH1 Facilitates Colorectal Cancer Progression by Promoting Oxidative Phosphorylation via the Mitochondrial Translocation of K63‐Linked Ubiquitinated PHB1

open access: yesAdvanced Science, EarlyView.
The RBR E3 ubiquitin ligase ARIH1, which is upregulated in colorectal cancer cells, promotes cell growth and metastasis and correlates with an unfavorable CRC prognosis. Mechanistically, ARIH1 catalyzes K63‐linked ubiquitination of PHB1, enhancing the interaction between PHB1 and Akt.

Dynamic Cap‐Mediated Substrate Access and Potent Inhibitor Design of Monkeypox Virus I7L Protease

open access: yesAdvanced Science, EarlyView.
The first crystal structure of MPXV I7L protease, revealing its unique dimeric form is resolved. The structures and MD simulations uncovered a dynamic cap region that regulates substrate access to the active site. The structural basis of substrate recognition and the catalytic mechanism are elucidated, which led to the development of a FRET‐based assay

Wide‐Temperature Electrolyte Design via Cation‐Anion Solvation Engineering for 4.6 V Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This work proposed a synergistic cation‐anion solvation engineering strategy for wide‐temperature and high‐voltage electrolytes. The superior ionic conductivity under subzero temperatures, excellent thermal stability, and induced inorganic‐rich cathode‐electrolyte interphase endow the LiCoO2 cathodes reliable performance under harsh conditions with a ...
