We investigate the effect of focused-ion-beam (FIB) irradiation on spin waves with sub-micron wavelengths in Yttrium-Iron-Garnet (YIG) films. Time-resolved scanning transmission X-ray (TR-STXM) microscopy was used to image the spin waves in irradiated regions and deduce corresponding changes in the magnetic parameters of the film. We find that the changes of Gairradiation can be understood by assuming a few percent change in the effective magnetizationof the film due to a trade-off between changes in anisotropy and effective film thickness.

In recent years, the health challenges linked to frailty in the elderly, particularly those worsened by cigarette smoke, have become more pronounced. However, quantitative studies examining the impact of smoking dosage on frailty in this population remain limited. To address this gap, we developed a model using smoke-exposed elderly mice.

Based on our previous work, a series of imidazole-based small molecules were designed and synthesized as HDAC3 inhibitors. Among them, compound showed selective HDAC3 inhibition activity with an IC of 53 nM (SI = 75 for HDAC3 over HDAC1). Further studies revealed that could dose-dependently induce the expression of PD-L1 in MC38 cells by activating the PD-L1 transcription.

The aim of the study was to evaluate the anxiolytic effect of GB-115 as a tablet form with subchronic oral administration in comparison with phenazepam in nonhuman primates.
Materials And Methods: The study was conducted on four male rhesus monkeys (Macaca mulatta) aged 5.
