Assessing radiofrequency safety of active implants by measuring induced radiofrequency currents using MRI

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 868-880, February 2026.
Abstract Purpose During MRI in the presence of active wire‐like implants, such as deep brain stimulation leads, there is a risk of thermal lesions in tissues adjacent to implant contacts due to radiofrequency currents induced in the wire. Currently, there is no established method to evaluate the radiofrequency (RF) safety of an implant in situ, due to ...

Missense Variants in the Second Transmembrane Domain of TMEM17 Disrupt Its Stability and Function and Lead to a Wide Phenotypic Spectrum of Ciliopathies

Clinical Genetics, Volume 109, Issue 2, Page 305-315, February 2026.
Missense variants in TMEM17 disrupt its localization and function at the ciliary transition zone, leading to a wide range of ciliopathy phenotypes, from OFD6 and Joubert syndromes to Meckel syndrome. ABSTRACT Ciliopathies are rare genetic disorders characterized by significant genetic and phenotypic variability.

A Cytochrome c‐Containing Periplasmic Nitrate Reductase in the Acetogen Sporomusa ovata

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Sporomusa ovata, a cytochrome‐containing, acetogenic bacterium, conserves energy by reduction of carbon dioxide to acetate. Nitrate serves as additional electron acceptor and is reduced to ammonium, resulting in increased growth and reduced acetate production.
