Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Systematic Review of Patient‐ and Observer‐Reported Outcomes of Fatigue in Pediatric Neuromuscular Disorders

Muscle &Nerve, EarlyView.
ABSTRACT Fatigue is a burdensome symptom for pediatric populations with neuromuscular disorders, often assessed using patient‐ and observer‐reported outcomes. The three aims of this systematic review are to: (1) explore, summarize and critically appraise primary studies that measure fatigue in pediatric neuromuscular disorders using patient‐ and ...

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape

A Possible Case of Temporomandibular Joint Dislocation, Trepanation, and Metabolic Bone Disease in a Young Adolescent From North‐Central Myanmar (1000–700 bce)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT This osteobiography explores the life history of an adolescent who lived during the early‐mid Bronze Age (c. 1000–700 bce) and was buried at Nyaung'gan, a site in north‐central Myanmar. Burial 3b had multiple skeletal lesions, and their bones were covered in well‐remodeled subperiosteal new bone.
