Exploring the Immobilization Strategies of Lewis Bases on Lignocellulosic Bamboo Shavings and their Applications in Cycloaddition of CO2 and CO2 Derivatives

open access: yesAdvanced Sustainable Systems, EarlyView.
Biobased bamboo shavings are used to immobilize Lewis base catalysts for CO2 valorization. Two methods are investigated for immobilization of catalysts: covalent isocyanate coupling and silane condensation. The isocyanate method achieves 100% conversion of cyclic carbonate starting from epoxides, whereas the silane method yields glycerol carbonate with

Multiomics Analyses Reveal an Essential Role of Tryptophan in Treatment of csDMARDs in Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
Rheumatoid arthritis is a disease characterized by joint inflammation. Approximately 50% of patients show insufficient response to traditional synthetic disease‐modifying antirheumatic drugs. This study aims to elucidate differential molecular profiles of the mechanisms underlying drug responses through multi‐omics strategy.

Genome‐Wide by Lifetime Environment Interaction Studies of Brain Imaging Phenotypes

open access: yesAdvanced Science, EarlyView.
This study explores genome‐wide by lifetime environment interactions on brain imaging phenotypes. Gene‐environment interactions explain more phenotypic variance than main effects, pinpoint regulatory variants, and reveal exposure‐specific biological pathways.
