With the rising demand for sustainable proteins, edible insects such as silkworm pupae are gaining recognition for their high-quality protein and essential nutrients. Advanced technologies like high hydrostatic pressure (HHP) processing have the potential to enhance the functional properties of insect proteins. This study investigated the application of HHP to silkworm pupa protein, focusing on its effects on physicochemical properties, functional characteristics, and bioactivity. HHP treatments at 400 and 600 MPa significantly enhanced emulsifying and foaming capacities, as well as antioxidant activity. Furthermore, HHP-assisted extraction facilitated protein unfolding and increased the exposure of hydrophobic groups on the protein surface, which likely contributed to improvements in protein solubility and antioxidant function. These findings provide valuable insights into the potential of HHP to enhance the quality of edible insect proteins for food applications.

Background: The peritoneal dialysis (PD) regimes should be individualized based on clinical tolerance and adequacy. Routine hydrostatic intraperitoneal pressure (IPP) measurements have been suggested to define optimal intraperitoneal dialysate volume (IPV), data on applicability and variability in clinical routine are few.
Methods: We retrospectively analysed 655 IPP measurements monthly performed in 21 children on stable automated PD.

Transition metal dichalcogenides display a high technological potential due to their wide range of electronic ground states. Here, we unveil that by tuning hydrostatic pressure P, a cascade of electronic phase transitions can be induced in the few-layer transition metal dichalcogenide 1T'-WS. As P increases, we observe the suppression of superconductivity with the concomitant emergence of an anomalous Hall effect (AHE) at GPa.

In this work, the high-temperature and high-pressure ferroelectric, structural, and electrical transport properties for CuInP2Se6 upon compression and decompression under different hydrostatic environments were comprehensively studied via Raman spectroscopy, electrical conductivity, and high-resolution transmission electron microscopy observations. Upon non-hydrostatic pressurization, CuInP2Se6 experienced two successive phase transitions at 5.4 and 14.

Introduction: Glioblastoma (GBM) is the most malignant of the astrocytomas, primarily involving the cerebral hemispheres and cerebral cortex. It is one of the fatal refractory solid tumors with a 5-year survival rate of only 5% in adults. Cells in biological tissues are subjected to mechanical forces, including hydrostatic pressure, shear stress, compression and tension.
