High hydrostatic pressure
The use of high pressure processing (HPP) in the food industry was developed as an alternative to common thermal processes, such as pasteurization and sterilization, to produce a microbiologically safe food while avoiding and reducing undesirable changes in sensory, physiochemical and nutritional properties of foods. The use of high pressure at high temperatures as a tool for sterilization (hig...
متن کاملRenal Interstitial Hydrostatic Pressure During Pressure Natriuresis
Pressure natriuresis may be mediated through increases in inner medullary vasa recta blood flow (QvR). By means of acute renal decapsulation to prevent increases in renal interstitial hydrostatic pressure (RIHP), the effect of increases in QVR in the presence and absence of changes in RIHP in the natriuretic and diuretic responses to increases in renal perfusion pressure (RPP) was evaluated. Bl...
متن کاملThe Dependence of T c on Hydrostatic Pressure in Superconducting MgB
The dependence of Tc on pure hydrostatic pressure has been determined for the first time on the recently discovered superconductor MgB2 . Using a He-gas apparatus, we find that Tc decreases under pressure to 0.5 GPa at a significantly smaller rate, dTc/dP ≃ −1.11± 0.02 K/GPa, than found in other studies under less hydrostatic pressure conditions. The value of the logarithmic volume derivative, ...
متن کاملHydrostatic pressure dependence of isoelectronic bound excitons in beryllium-doped silicon.
Photoluminescence ~PL! from the recombination of excitons bound to isoelectronic Be2 dopants in bulk silicon is measured for pressures up to 60 kbar and temperatures down to 9 K. PL from excitons bound to this Be2 trap is analyzed by using the Hopfield-Thomas-Lynch model, extended to treat more complex isoelectronic dopants, and several different binding potentials. This modified model describe...
متن کاملHydrostatic pressure influences histone mRNA.
Exposure of HeLa S3 cells to high hydrostatic pressure (6.89 x 10(3) to 6.89 x 10(4) kPa: 1000 to 10,000 lbfin-2) reduced core and H1 histone mRNA levels as determined by hybridization to specific histone DNA probes. At 4.14 x 10(4) kPa for 10 min core histone and H1 histone mRNA levels were reduced 32-38% and 56%, respectively. At 30 min postdecompression core mRNA levels returned to atmospher...
