Signaling properties of the human chemokine receptors CXCR4 and CXCR7 by cellular electric impedance measurements. [PDF]

PLoS ONE, 2017
The chemokine receptor 4 (CXCR4) and 7 (CXCR7) are G-protein-coupled receptors involved in various diseases including human cancer. As such, they have become important targets for therapeutic intervention.

Improve the quality of "dead band" audio-frequency magnetotelluric impedance data using electric field remote reference

矿业科学学报, 2022
Magnetic remote-reference is the most practical noise suppression method in magnetotelluric data processing.In actual audio-frequency magnetotelluric (AMT) sounding observation, usually the "one with three" or "one with four" acquisition method is used ...

Do metal implants for total hip arthroplasty affect bioelectrical impedance analysis? A retrospective study

BMC Musculoskeletal Disorders, 2023
Background Evaluation of body composition after total hip arthroplasty (THA) is essential because it can be used to evaluate muscle and functional recovery. Muscle volume and degeneration are evaluated using computed tomography (CT).

Monitoring Freeze-Damage in Grapefruit by Electric Bioimpedance Spectroscopy and Electric Equivalent Models

Horticulturae, 2022
Grapefruit is a cold-sensitive citrus fruit, and freezing can spoil the harvest when the fruit is still on the tree and even later during manufacturing and transport due to inappropriate postharvest management.
