Summary: Swellable poly(ionic liquid)s (SPILs) are ionic polymers with unique swelling ability, which depends on the compatibility of polymer chains with solvent molecules and the dissociation of ionic groups in solvents. Compared to non-swellable poly(ionic liquid)s, SPILs have good solvent affinity and distinctive physicochemical properties, making them widely applicable in catalysts, actuators, sensors, absorbents, and separation membranes, among others.

Summary: Besides its typical halogen donor behavior, CF3Cl is shown to reveal a new interaction site with CO2, forming a C-dot-dot-dot-Cl tetrel bond through the Cl equatorial belt. Additionally, a secondary C-dot-dot-dot-O tetrel bond and a F-dot-dot-dot-O halogen bond may also contribute to the relative orientation of the moieties in the complex.

Summary: Phosphonic acids are important organophosphorus compounds widely used in various fields. A convenient and efficient method for the preparation of phosphonic acids is silyldealkylation with bromotrimethylsilane (BTMS), followed by desilylation. We investigated microwave irradiation as an acceleration method for BTMS reactions and found that it had significant advantages over conventional heating, including higher yields and chemoselectivity. This method was also applied to the preparation of antiviral and anticancer drugs, showing great potential.

Summary: DNA cross-link (ICLs) can cause lethal events such as cancer or bone marrow failure during replication and transcription. The Fanconi Anemia (FA) pathway proteins are responsible for repairing ICLs, but the details of the pathway are not fully known. Methods to create DNA containing ICLs are crucial for further understanding cross-link repair. A major method to form ICLs in vivo is through DNA reaction with acetaldehyde from ethanol metabolism. This research presents an efficient approach using a novel N2-((R)-4-trifluoroacetamidobutan-2-yl)-2'-deoxyguanosine phosphoramidite for preparing reduced acetaldehyde ICLs. The simplicity, efficiency, and stability of this method will contribute to future studies on cross-link repair.

Summary: This study compared different life cycle stages of the red alga Gracilaria dura, focusing on morphological structures, growth performance, agarose characteristics, biochemical, and molecular profiling. Significant differences were found in growth rates and agarose yield among male gametophytes, tetrasporophytes, and cystocarpic female gametophytes. Metabolomic analysis revealed critical differences in alanine, lactate, and isethionic acid among stages, while genetic correlation analysis showed an average polymorphism of 47.02%. The study concludes that characterizing and differentiating isomorphic life phases of G. dura could be valuable for selecting appropriate cultivars for commercial farming and breeding programs.

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.
