Published: Jan. 25, 2023

Amyloid fibrils have generated steadily increasing traction in the development of natural and artificial materials. However, it remains a challenge to construct bulk amyloid films directly from due their intrinsic brittleness. Here, facile general methodology fabricate macroscopic tunable via fast electrostatic self-assembly at air-water interface is introduced. Benefiting excellent templating properties for nanoparticles (such as conductive carbon nanotubes or magnetic Fe3 O4 nanoparticles), multifunctional with are constructed. As proof-of-concept demonstrations, magnetically oriented soft robotic swimmer well-confined movement trajectory prepared. In addition, smart sensor high sensitivity external fields fabricated combination films. This strategy provides convenient, efficient, controllable approach preparation amyloid-based related devices.

The objective of this work was to investigate the impact calcium hydrogen phosphate (CHP), curdlan gum (CUR), and TGase (TG) on digestion absorption surimi gel. In study, an vitro model combined with C57BL/6 mice used analyze digestive absorbed juices comprehensively. results showed that addition CHP CUR products a decreasing trend in α-helix content secondary structure substrate proteins after digestion, which slowed down digestibility gel by 4.27% 9.07% (p < 0.05). However, there no significant difference TG compared control group. Digested did not cause any nutritional loss. can effectively lipid accumulation improve their growth performance. All three additives promote release peptides, small peptide intestinal chyme group significantly increased 317.33 µg·mL-1 This study provides theoretical basis guidance for producing higher value.

Magnetic Fields Reduce Apoptosis by Suppressing Phase Separation of Tau-441

Research, Journal Year: 2023, Volume and Issue: 6

Published: Jan. 1, 2023

The biological effects of magnetic fields (MFs) have been a controversial issue. Fortunately, in recent years, there has increasing evidence that MFs do affect systems. However, the physical mechanism remains unclear. Here, we show (16 T) reduce apoptosis cell lines by inhibiting liquid-liquid phase separation (LLPS) Tau-441, suggesting MF effect on LLPS may be one mechanisms for understanding "mysterious" magnetobiological effects. Tau-441 occurred cytoplasm after induction with arsenite. phase-separated droplets recruited hexokinase (HK), resulting decrease amount free HK cytoplasm. In cells, and Bax compete to bind voltage-dependent anion channel (VDAC I) mitochondrial membrane. A number molecules increased chance binding VDAC I, leading Bax-mediated apoptosis. presence static MF, was marked inhibited recruitment reduced, an probability I decreased thus reducing Our findings revealed new from perspective LLPS. addition, these results potential applications environments, such as this study, treatment LLPS-related diseases.
