Bioconjugation technologies enable covalent attachment of diagnostic or therapeutic effectuators onto biological targets, allowing for the precise delivery of desired drugs to the intended targets with enhanced potency, selectivity, specificity, and prolonged duration of action. As the number of bioconjugation techniques has grown enormously, identification and in-depth characterization of in-process products play a critical role in the development of covalent drug conjugates. This is especially significant in light of the increased complexity of novel biotherapeutics derived from biological matrices.

However, the gene expression changes of these neurons remain unknown, making it difficult to determine the diagnosis or to dissect the mechanism of drug-resistant epilepsy. By integrating whole-cell patch clamp recording and single-cell RNA-seq approaches, we identified a transcriptionally distinct subset of cortical pyramidal neurons.

The impact of the interface on the electrical and optical properties of g-CN/SnS was explored using first-principles calculations in this study. The results show that, at the hetero-interface, a conventional type-II band forms, resulting in a lower band gap than that in the g-CN and SnS monolayers.

Based on studies on the balance of force couples of the rotator cuff, more scholars believe that attention should be paid to the reconstruction of the force couples of the rotator cuff. This study proposes a modified surgical approach that integrates an arthroscopic-assisted lower trapezius transfer with autologous hamstring tendon and partially augmented rotator cuff repair for irreparable massive rotator cuff tears, with a focus on restoring the anterior-posterior shoulder force couple.

TCRγδ recognizes protein/nonprotein ligands without the help of the major histocompatibility complex (MHC), especially via direct binding to protein ligands, which is dependent primarily on the δ chain complementary determining region 3 (CDR3δ). However, the mechanism of protein‒antigen recognition by human γδ TCRs remains poorly defined.

This study introduces the Fukushima Contaminated Water Risk Factor (FCWRF), which integrates three components─radionuclide diffusion, bioaccumulation, and global seafood trade─to evaluate the spatiotemporal distribution of risks based on actual discharge practices. Results suggest that comprehensive risks exceeding 2 orders of magnitude beyond the baseline will be transferred to six continents globally.
