We performed two types of conventional triaxial experiments on fluid-saturated sand aggregates under room temperature conditions: Two hydrostatic tests (OS-04 and OS-17) were done at P c up to 55 and 105 MPa, respectively. Decane-saturated test OS-04 was performed at fixed confining pressure steps of 2.5 MPa, while during each step, the …

The FTIR spectra of TTR 105–115 samples that had been allowed to aggregate for longer periods of time have a more prominent band at ∼1624 cm −1, similar to that in the spectrum of the sample after aggregation for one day following pressure treatment.On day 4 of the aggregation process AFM shows an abundance of fibrils …

High pressure homogenization at 15 and 30 kpsi caused the dissociation of the large protein aggregates (>1 μm) into supramolecular aggregates and 11S, which may unmask the hydrophobic regions buried inside the …

P22 tailspike protein was reduced from 41% to 18% by pressure treatment of a 100 ptg/ml solution (28). However, pressure has not been used as a tool to obtain native protein from insoluble aggregates at relatively high protein concentrations, with high yields, nor from covalently crosslinked aggregates or inclusion bodies.

High pressure processes have been used in the food industry for over 50 years and large scale (300 L) systems are commercially available, enabling production of proteins on the kilogram scale. This review summarizes the utility of high pressure refolding to remove and refold protein aggregates, enhance therapeutic proteins, and facilitate ...

Quinoa protein isolates treated with pH 12 and high-pressure homogenization increased the solubility from 7.85% to 78.97%, creating quinoa protein isolate nanoaggregates with an average size around 54 nm. The quinoa isolate aggregates were used to produce oil-in-water nanoemulsions, which demonstrated the good stability …

Higher pressure (400–600 MPa) caused small particles to aggregate and form larger aggregates. Additionally, HPP treatment regulates aggregation behavior …

Furthermore, in situ high pressure UV spectroscopic studies show that the local environment of Trp residues in rhGH, which is perturbed in aggregates, becomes native-like at high pressures, at a rate greater than the rate of aggregate dissolution. Thus, under high hydrostatic pressure, proteins can be both disaggregated and refolded.

Characterization of protein aggregates in cream and skimmed human milk after heat and high-pressure pasteurization treatments Food Chem. 2023 Dec 15 ... insoluble protein aggregates at milk fat globule membrane (MFGM) were formed by disulfide and non-covalent bonds, but insoluble skim milk protein aggregates were only …

High pressure and heat-induced potato protein aggregates: A comparison of aggregation kinetics, structure modifications, and protein interactions. - ScienceDirect. Abstract. Food …

The utility of high pressure refolding to remove and refold protein aggregates, enhance therapeutic proteins, and facilitate manufacturing improvements at industrial scales is summarized. Non-denaturing pressures of around 2000 bar are effective for eliminating and refolding protein aggregates and may be applicable in various phases of protein …

Micromechanics of High-Pressure Compaction in Granular Quartz Aggregates. Suzanne J. T. Hangx, Nicolas Brantut. First published: 04 June 2019. https://doi/10.1029/2018JB016494. Citations: 10. Sections. PDF. Tools. Share. Abstract.

High pressure prevents protein reaggregation during refolding since aggregates can be dissociated and refolded at conditions that favor the native protein conformation, inhibiting the formation of ...

Abstract. Lightweight aggregate concrete (LWAC), characterized with low density and high crushing strength to apparent density ratio, is a potential construction material for modern concrete structures. However, experiences in pumping LWAC to high-rise buildings are insufficient and the pumping pressure of fresh concrete may differ from …

The observed effect of DHP treatment on the surface properties of thermal pea albumin aggregates showed that high-pressure treatment had little impact on the ing properties of these aggregates at low pH but considerably enhanced them at the neutral pH . DHP treatment has also been used to increase the solubilities of heated …

To add water (hydrogen), high-pressure annealing experiments were performed at the pressure of 4.0 GPa and temperature of 1373 K, where the annealing time is 3 hr and the oxygen partial …

Higher pressure (400–600 MPa) caused small particles to aggregate and form larger aggregates. Additionally, HPP treatment regulates aggregation behavior mainly by affecting the higher-order structure (tertiary and quaternary structures) of MRJPs, rather than by altering its secondary structure.

Breaking the initial aggregates and establishing new rearrangements and interactions within the protein clusters would extensively hide the hydrophobic groups and would slightly decrease the SS and increase the SH F content. A high microfluidization pressure (130 MPa) had a weaker effect on H o compared with a pressure of 70 MPa. …
