Pancreas, Muscle, and Subcutaneous Fat Atrophy in Patients Undergoing Radiation for Neuroblastoma
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background/Objectives Radiation therapy (RT) is part of standard‐of‐care therapy in high‐risk neuroblastoma (HR‐NBL) but can significantly affect nearby tissue. The objectives of this study were (1) to characterize changes in pancreas volume after RT and (2) to characterize changes in body composition, including body weight percentile ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
