CaATPase enzyme activities and lipid and protein oxidations of grass carp (Ctenopharyngodon idellus) stored at 4 °C for 30 min under electromagnetic fields.

This study evaluated 12 mT electromagnetic fields (100–400 Hz) applied during 30 minutes of cold storage (4 °C) of grass carp. EMF exposure was associated with increased CaATPase activity and frequency-dependent changes in protein and lipid oxidation. NMR results suggested altered water–protein interactions, and the…

Extremely low frequency electromagnetic fields promote mesenchymal stem cell migration by increasing intracellular Ca and activating the FAK/Rho GTPases signaling pathways in vitro.

This in vitro study exposed human bone marrow-derived mesenchymal stem cells to extremely low frequency EMF (7.5–70 Hz, 1 mT) generated by Helmholtz coils. The authors report increased MSC migration across all tested frequencies. Mechanistically, the effect is described as dependent on intracellular calcium and…

Gerontechnologies for Older Patients with Heart Failure: What is the Role of Smartphones, Tablets, and Remote Monitoring Devices in Improving Symptom Monitoring and Self-Care Management?

This review-style article discusses gerontechnologies—mobile applications on smartphones/tablets and remote monitoring systems—for outpatient symptom monitoring and self-care management in older adults with heart failure. It frames these tools as potentially cost-effective and accessible when designed for older…

[Treatment of benign prostatic hyperplasia by radiofrequency (TUNA): a monocentric study of 28 cases treated in ambulatory surgery].

This monocentric study evaluated outpatient feasibility and outcomes of radiofrequency transurethral needle ablation (TUNA) for benign prostatic hyperplasia in patients who did not respond to medical therapy. In the outpatient subgroup, urinary symptom scores, quality of life, flow measures, and residual urine…

In vivo quantification of contrast agent concentration using the induced magnetic field for time-resolved arterial input function measurement with MRI.

This Medical Physics article presents a phase-based MRI method to quantify paramagnetic contrast agent concentration by inverting susceptibility-induced magnetic field shifts, aiming to improve arterial input function (AIF) measurement in DCE-MRI. After in vitro validation, the approach was applied in vivo in 14…
