Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

The Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Improving tumor marker comparability: A case series on harmonizing carbohydrate antigen 19‐9 and carbohydrate antigen 15‐3 measurements across diverse measurement systems

VIEW, EarlyView.
CA19‐9 and CA15‐3 measurements from seven contemporary immunoassay systems were compared using 464 and 499 native serum samples, respectively. Inter‐system correlations were higher for CA15‐3 than for CA19‐9, and only a limited number of systems met biological variation‐derived bias criteria.

Interlaboratory performance testing on EPIC v2.0 CNS tumor profiling demonstrates high reproducibility of tumor classification but reveals the need for harmonized copy number variation reporting

Brain Pathology, EarlyView.
Using the Infinium MethylationEPIC v2.0 array and Heidelberg Brain Tumor Classifier v12.8, 24 international laboratories achieved highly reproducible CNS tumor classification (97.9% correct; median β‐correlation r = 0.99), while copy number variation interpretation showed substantial interlaboratory variability, highlighting the need for harmonized CNV

Associations between prior wasting malnutrition and indices of insulin secretion and sensitivity among six cohorts from Asia and Africa: The SAMPA study

Diabetic Medicine, EarlyView.
Abstract Aims The role of prior wasting malnutrition (PM) in determining insulin sensitivity and secretion in low‐ and middle‐income countries (LMICs) remains unclear. We investigated associations of insulin indices with PM and whether these were modified by current body mass index (BMI).

Bringing Gene Therapy Into Real World Clinical Practice

Haemophilia, EarlyView.
ABSTRACT Introduction Adeno‐associated virus (AAV)‐based gene therapy for haemophilia has shifted therapeutic paradigms by enabling hepatic gene transfer, restoring endogenous clotting factor expression, and reducing reliance on conventional prophylactic treatments. Two products, valoctocogene roxaparvovec (haemophilia A) and etranacogene dezaparvovec (
