Challenges of human platelet lysate production: Results of an International Survey of the ISBT Working Party on Cellular Therapies

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Global demand is rising for human platelet lysate (HPL) in the manufacture of cell‐based medicinal products, but platelet resources are scarce. As protocols for the production process and quality testing are heterogeneous, the Working Party on Cellular Therapies of the International Society of Blood Transfusion (ISBT)

Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 10, Page 3664-3674, October 2026.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Consensus Guidelines for Diagnosis and Management of Pyruvate Dehydrogenase Complex Deficiency

Journal of Inherited Metabolic Disease, Volume 49, Issue 6, November 2026.
ABSTRACT Primary pyruvate dehydrogenase complex deficiency (PDCD) comprises a group of monogenic disorders caused by pathogenic variants in genes encoding subunits of, or regulatory components affecting, the pyruvate dehydrogenase complex. The clinical phenotype spans a broad continuum, ranging from early onset congenital lactic acidosis to infantile ...

Noise‐Limited Bit Precision in Ferroelectric Synaptic Transistors for High‐Resolution Neuromorphic Computing

Advanced Functional Materials, Volume 36, Issue 84, 19 October 2026.
Low‐frequency noise spectroscopy defines the resolvable conductance states of synaptic FeFETs by coupling read‐current fluctuation with usable dynamic range. The resulting noise‐limited bit precision establishes a universal, device‐agnostic reliability metric beyond the memory window, enabling quantitative benchmarking and rational design of high ...
