The role of phase angle and standardized phase angle in assessing nutritional status and predicting complications in gastrointestinal cancer. [PDF]
PLoS ONEObjectiveThis study aims to look at the link between bioelectrical impedance analysis (BIA), especially phase angle (PA) and standardized phase angle (SPA), and how often postoperative infectious complications occur in patients with gastrointestinal ...

Bioimpedance basics and phase angle fundamentals
Reviews in Endocrine and Metabolic Disorders, 2023 AbstractMeasurement of phase angle using bioimpedance analysis (BIA) has become popular as an index of so-called “cellular health”. What precisely is meant by this term is not always clear but strong relationships have been found between cellular water status (the relative amounts of extra- and intracellular water), cell membrane integrity and cellular

Associations of phase angle and its change with all-cause mortality among community-dwelling older Japanese adults [PDF]
Scientific ReportsPhase angle measured by bioimpedance is considered to reflect muscle quality and nutritional status. This study investigated the associations of phase angle and its 5-year change with all-cause mortality among community-dwelling older Japanese adults.

Active limited-angle tomographic phase microscope [PDF]
Journal of Biomedical Optics, 2015 We demonstrate an active, holographic tomography system, working with limited angle of projections, realized by optical-only, diffraction-based beam steering. The system created for this purpose is a Mach–Zehnder interferometer modified to serve as a digital holographic microscope with a high numerical aperture illumination module and a spatial light ...

Impact of sarcopenia and phase angle on mortality of the very elderly
Journal of Cachexia, Sarcopenia and Muscle, 2023 Background Sarcopenia is a major component of geriatric syndrome and associated with poor clinical outcomes and mortality. However, diagnosing sarcopenia in the very elderly is difficult, and data on its epidemiology and devastating effects in this group
