Comparison of Centrifugal and Pulsatile Perfusion to Preserve Donor Kidneys Using Ex Vivo Subnormothermic Perfusion

open access: yesJournal of Investigative Surgery, 2022
Objective We have previously demonstrated benefits of kidney preservation utilizing an oxygenated subnormothermic ex vivo perfusion platform. Herein, we aim to compare pulsatile versus centrifugal (steady and uniform flow) perfusion with the goal of ...

Health condition assessment of centrifugal pump based on AHP-TOPSIS comprehensive evaluation method

open access: yesGong-kuang zidonghua, 2022
In view of the problem of centrifugal pump impeller wear, the existing research mostly concentrates on numerical simulation analysis, vibration signal analysis and wear detection of impeller wear. There are few studies on the working condition parameters

A Novel Centrifugal Filtration Device

open access: yesSeparations, 2022
In the proposed centrifugal filtration device, a filter is mounted in the center of the centrifugal chamber. The particles move towards the centrifuge wall away from the filter under centrifugal force, so a filtration cake is unlikely to accumulate here.

Unstable Flow Structures Present at Different Rotational Velocities of the Centrifugal Compressor

open access: yesEnergies, 2020
Unstable flow structures cause inevitable energy losses in all power energy systems, including turbomachines. In this study, a set of analyses was conducted with the use of spectral maps on the pressure signals obtained from an industrial centrifugal ...

The Human Centrifuge [PDF]

open access: yesMicrogravity Science and Technology, 2008
Life on Earth has developed at unit gravity, 9.81 m/s2, which was a major factor especially when vertebrates emerged from water onto land in the late Devonian, some 375 million years ago. But how would nature have evolved on a larger planet? We are able to address this question simply in experiments using centrifuges.

Haskap Juicing Method Effects on Haskap Juice Quality

open access: yesApplied Sciences, 2023
This research is the first study on the influence of juicing methods on the ‘Aurora’ haskap juice quality. Three common juice extraction methods, namely, using a steam juicer, a centrifugal juicer, and a bladder wine press, were applied for haskap juice ...

Aliquoting structure for centrifugal microfluidics based on a new pneumatic valve [PDF]

open access: yes, 2008
We present a new microvalve that can be monolithically integrated in centrifugally driven lab-on-a-chip systems. In contrast to existing operation principles that use hydrophobic patches, geometrically defined capillary stops or siphons, here we present ...

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
