Kidney Ultrasound for Nephrologists: A Review

Kidney Medicine, 2022
Ultrasound imaging is a key investigatory step in the evaluation of chronic kidney disease and kidney transplantation. It uses nonionizing radiation, is noninvasive, and generates real-time images, making it the ideal initial radiographic test for ...

Analytical Approximations for Calculating the Escape and Absorption of Radiation in Clumpy Dusty Environments [PDF]

, 1999
We present analytical approximations for calculating the scattering, absorption and escape of nonionizing photons from a spherically symmetric two-phase clumpy medium, with either a central point source of isotropic radiation, a uniform distribution of ...

Nonthermal Food Processing Technologies: A Comprehensive Review

Future Postharvest and Food, EarlyView.
The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Femoral Skeletal Growth in Early Infancy Assessed by Radiofrequency Echographic Multi‐Spectrometry

Journal of Clinical Ultrasound, EarlyView.
Radiofrequency echographic multi‐spectrometry (REMS) acquisition of raw ultrasound radiofrequency signals from neonatal bone. Signals undergo preprocessing and frequency‐domain analysis to extract spectral features reflecting bone properties. A software‐guided procedure then identifies and selects standardized regions of interest (ROIs).

A Genetic Reporter for Visualizing Nitroreductase Activity Using Magnetic Resonance Imaging

Chemistry–Methods, Volume 6, Issue 5, May 2026.
We introduce a reporter gene technology to noninvasively visualize bacterial nitroreductase activity. Our method utilizes a magnetic resonance imaging (MRI) reporter based on aquaporin, which is fused to a destabilizing domain, resulting in their degradation (off‐state).
