Summary: Optimizing the pretreatment conditions for lignocellulosic biomass is crucial for obtaining high purity fractions, especially a lignin polymer that can be easily used for valuable applications. This study used wheat straw as a sample and pretreated it in organic acid-based organosolv medium at mild conditions. The chemical structure and kinetics of lignin were analyzed using various techniques, and the modifications during the organosolv pretreatment were quantified. The extraction kinetics of lignin were successfully assessed using a potential degree of delignification model.

Summary: This study used molecular dynamics simulations to explore the pyrolysis mechanism of wheat straw, and found that gas production increases and tar yield initially increases and then decreases with temperature. CO and CO2 molecules mainly come from the cleavage of CHO2 radicals, and a large amount of H2O molecules are generated through dehydration. In addition, phenyl rings reflect improved thermostability.

Summary: A characteristic Lignin-first strategy was developed through comprehensive investigation of the oxy-organosolv delignification processes under mild conditions. The results showed that the lignin yield could reach about 50% under the optimized process conditions. The use of oxygen induced significant lignin dissolution without affecting the carbohydrate component and lignin structure, resulting in uniform lignin degradation. Additionally, the employment of oxygen extended the lignin removal stage and increased the delignification rate compared to conventional methods.

Summary: This study investigated the role of hydrogen gas in the reductive catalytic fractionation (RCF) of wheat straw biomass. It was found that hydrogen gas can enhance lignin depolymerization and increase the yield of phenolic monomers. In the presence of hydrogen gas, the yield of phenolic monomers increased from approximately 12 wt% to 25 wt% of acid-insoluble lignin in the initial biomass. Additionally, using ethanol as a hydrogen-donor solvent resulted in the highest yield of monophenolic compounds.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
