Many research programs focus on the molecular dynamics of living cells. This research requires cells to be adhered to a substrate while retaining the innate motility of their surface molecules. Lipid bilayer-based systems fulfill this requirement, although current methods are complicated and their utility is limited. We developed a simple and rapid method for reproducible preparation of homogeneous glass-supported lipid bilayers. Our method provides a facile means for bioimaging and analysis of molecular dynamics in living cells.

Controlling intermolecular interactions, such as triplet-triplet annihilation (TTA) and triplet-polaron annihilation (TPA), is crucial for achieving high quantum efficiency in organic light-emitting diodes (OLEDs) by suppressing exciton loss. This study investigates the molecular design of tetradentate Pt(II) complexes used for singlet exciton harvesting in fluorescent OLEDs to elucidate the relationship between the chemical structure of the ligands and exciton quenching mechanisms. It was discovered that the bulkiness of substituents is pivotal for maximizing quantum efficiency in these devices.

Objective: Previous experiments have demonstrated that BGM0504, a GLP-1R/GIPR dual agonist drug by molecular dynamics-guided optimization, had enhanced agonistic activity compared to tirzepatide. This study aims to investigate its safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) in Chinese healthy volunteers.
Methods: A randomized, double-blind, placebo-controlled and dose-escalation Phase I study was conducted as follows: a single dose (2.

A full-scale structural search was performed using density functional theory calculations and a universal structural prediction evolutionary algorithm. This produced a lowest energy two-dimensional (2D) CoB structure. The CoB-1 global minimum structure has unusual inverse double sandwich features.

Preimplantation embryonic development is orchestrated by dynamic changes in the proteome and transcriptome, regulated by mechanisms such as maternal-to-zygotic transition. Here, we employed label-free quantitative proteomics to comprehensively analyze proteome dynamics from germinal vesicle oocytes to blastocysts in mouse embryos. We identified 3490 proteins, including 715 consistently detected across all stages, revealing stage-specific changes in proteins associated with translation, protein modification, and mitochondrial metabolism.

A combination of femtosecond stimulated Raman scattering and surface-enhanced Raman scattering, termed surface-enhanced stimulated Raman scattering (SE-FSRS), was proposed to leverage both temporal precision and sensitivity for advanced molecular dynamics analysis. During the initial successful implementations of this approach, unexpected spectral distortions were observed, and several potential explanations were proposed. Further progress in this novel technique and its broader implementation requires a profound understanding of the factors influencing the shape of the registered spectra and the underlying mechanisms.
