Synthesis of Arsenocholine-Type Polycation Brush and Its Hydration Structure in Aqueous Solution.

Arsenocholine-containing methacrylate (MTAsB) inspired by marine organisms was synthesized by the reaction of 2-bromoethyl methacrylate and trimethylarsine to investigate its polymerization behavior and the fundamental properties of the resulting polymer. Controlled radical polymerization of MTAsB proceeded in the presence of a copper catalyst and imidazolium chloride at 60 °C for 8 h to give a water-soluble polycation with a 94% yield. The smaller amount of nonfreezing water and intermediate water of poly(MTAsB) was observed compared with that of the ammonium-containing polycations.

Tuning anomalous Hall conductivity antiferromagnetic configurations in GdPtBi.

The magnetic, electronic, and topological properties of GdPtBi were systematically investigated using first-principles density functional theory (DFT) calculations. Various magnetic configurations were examined, including ferromagnetic (FM) and antiferromagnetic (AFM) states, with particular focus on AFM states where the Gd magnetic moments align either parallel (AFM) or perpendicular (AFM) to the [111] crystal direction. For AFM, the in-plane angles were varied at = 0°, 15°, and 30° (denoted as AFM, AFM, and AFM, respectively).

Changes in the Pannexin Channel in Ileum Myenteric Plexus and Intestinal Motility Following Ischemia and Reperfusion.

Background: Intestinal ischemia affects the functioning of the Enteric Nervous System (ENS). Pannexin-1 channel participates in cell communication and extracellular signaling. Probenecid (PB) is a pannexin-1 channel inhibitor, which can be a potential treatment for intestinal ischemia.

Quasi-One-Dimensional Spin Dynamics in a Molecular Spin Liquid System.

The molecular triangular lattice system, β^{'}-EtMe_{3}Sb[Pd(dmit)_{2}]_{2}, is considered as a candidate material for the quantum spin liquid state, although ongoing debates arise from recent controversial results. Here, the results of electron spin resonance and muon-spin relaxation measurements on β^{'}-EtMe_{3}Sb[Pd(dmit)_{2}]_{2} are presented. Both results indicate characteristic behaviors related to quasi-one-dimensional spin dynamics, whereas the direction of anisotropy found in electron spin resonance is in contradiction with previous theories.

Effects of muscle contraction induced by electrical stimulation on fascial gliding: Evaluation by ultrasonography.

Purpose: This study investigates the effects of neuromuscular electrical stimulation (NMES)-induced muscle contraction on fascial gliding between the muscle and adjacent tissues and identifies factors that affect fascial gliding.

Methods: The gliding between the epimysium of the vastus lateralis muscle and the subcutaneous tissue was measured using a diagnostic ultrasound system during the subject's knee joint was flexed passively. The deep temperature, deep blood flow, and tissue hardness of the vastus lateralis muscle were measured to identify factors contributing to the changes in fascial gliding.
