Unraveling Chronic Pain: From Mechanisms and Risks to Diagnosis and Treatment

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Chronic pain arises through distinct molecular pathways categorized into nociceptive, neuropathic, and nociplastic types. Nociceptive pain begins with TRP channel activation in peripheral nociceptors, signaling via Aδ‐ and C‐fibers through the spinal dorsal horn and spinothalamic tracts to the brain, regulated by descending inhibition and involving ...

Emerging Neural Recording and Neurostimulation Technologies Based on Brain–Computer Interface: A Promising Approach for Neuropsychiatric Disorders

open access: yesMedComm, Volume 7, Issue 4, April 2026.
This review explores brain–computer interface (BCI)–based neural recording and stimulation for treating neuropsychiatric disorders. It details three emerging technologies: endovascular BCI for minimally invasive signal acquisition, BCI‐integrated epidural spinal cord stimulation for motor restoration, and closed‐loop deep brain stimulation for adaptive

RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2331-2344, April 2026.
ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.

Hypertrophic Cardiomyopathy as a Key Feature of MRAS‐Related Noonan Syndrome: New Case and Comprehensive Literature Review

open access: yesPrenatal Diagnosis, Volume 46, Issue 4, Page 581-588, April 2026.
ABSTRACT Noonan syndrome (NS) is a rare multisystemic condition among the RASopathy group, characterized by a broad phenotypic spectrum and genetic variability. It results from pathogenic variants in genes regulating the RAS/MAPK pathway, affecting cell proliferation and differentiation.
