Summary: In this study, a two-step hydrothermal pretreatment combined with alkali extraction method was used to deconstruct poplar cell walls for enzymatic hydrolysis, resulting in the removal of a significant amount of hemicelluloses and lignin. Confocal Raman microscopy revealed that hemicelluloses were unevenly removed from cell walls, mainly originating from the secondary wall. Water-soluble hemicelluloses were found to have a more branched structure compared to alkali-soluble hemicelluloses, with a linear backbone of (1 -> 4)-beta-D-Xylp and 4-O-Me-alpha-d-GlcpA side chains identified in hemicelluloses isolated from poplar. This work provides an efficient pathway to convert poplar into fermentable sugars and hemicelluloses with significant yield.

Summary: Hemicelluloses were extracted from a softwood acid sulfite pulp in a three-step procedure, resulting in a holocellulose pulp with minimal lignin content. Various analytical techniques were employed to study the chemical compositions and structures of the extracted hemicelluloses, revealing modifications in their structure due to sulfite pulping.

Summary: The influence of oxygen on the depolymerization of hemicelluloses and the formation of acids from monosaccharides during hydrothermal treatment of spruce chips was studied. The presence of dissolved oxygen significantly enhanced the depolymerization process and acid formation. Lower amounts of oxygen resulted in faster depolymerization, while it was slower in an inert atmosphere. Decreasing pH had an autocatalytic effect on polysaccharide hydrolysis and monosaccharide reactions.

Summary: The effect of p-TsOH differentiated fractionation of poplar sawdust, eucalyptus sawdust, and rice straw below 100°C was investigated. The results showed that p-TsOH can effectively remove most lignin and hemicellulose from poplar and eucalyptus sawdust, while retaining cellulose. For rice straw, p-TsOH removed most lignin but retained most hemicellulose and cellulose under similar conditions. The structures and compositions of the pretreatment residues were characterized, and the fractionation mechanism of biomass was analyzed.

Summary: Intensively managed poplar plantations have the potential to provide renewable biomass for bioenergy production, with clonal varieties being crucial for productivity on water-limited, marginal agricultural land. While carbon isotope discrimination is commonly used for selecting drought-resistant varieties, this study found that other traits like abaxial stomatal density were more accurate predictors of varietal performance under drought stress. A composite of all nine variables proved to be the best indicator of drought resistance in hybrid poplar varieties.

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.
