Purine Metabolism and Dystonia: Perspectives of a Long‐Promised Relationship

open access: yesAnnals of Neurology, Volume 97, Issue 5, Page 809-825, May 2025.
Purine pool imbalance in purine metabolism disorders, such as Lesch–Nyhan disease, intersects with dystonia pathogenesis. The recent discovery of gain‐of‐function IMPDH2 pathogenic variants in patients with prominent dystonic manifestations provides new insights into the link between dystonia and purinergic system defects.

Neural canal ridges: A novel osteological correlate of postcranial neuroanatomy in dinosaurs

open access: yesThe Anatomical Record, Volume 308, Issue 5, Page 1349-1368, May 2025.
Abstract In this article, we document the widespread presence of bony ridges in the neural canals of non‐avian dinosaurs, including a wide diversity of sauropods, two theropods, a thyreophoran, and a hadrosaur. These structures are present only in the caudal vertebrae.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.
