The Sm-Nd isotopic method in the geochronology laboratory of the University of Brasília

Anais da Academia Brasileira de Ciências, 2000
Nd isotopes represent one of the best tools to investigate the processes involved in the evolution of the continental crust and mantle. This is due mainly to the similar geochemical behaviour of Sm and Nd, both light rare earth elements, which inhibits ...

Aptamer‐Targeted PrPC Drives Colorectal Cancer Metastasis via a LYN‐STAT3 Complex and Enables Liquid Biopsy Detection

Advanced Science, EarlyView.
The aptamer WHY‐3E identifies PrPC as a CRC driver. Stabilized by USP18, endocytosed PrPC forms a LYN/STAT3 complex, upregulating MSN transcription to promote metastasis. Crucially, WHY‐3E sensitively detects PrPC‐positive circulating exosomes, establishing a robust theoretical foundation for non‐invasive clinical diagnostics.

Safety of Sodium‐Ion Batteries: Evaluation and Perspective from Component Materials to Cells, Modules, and Packs

Advanced Energy Materials, EarlyView.
This review provides a bottom‐up evaluation of sodium‐ion battery safety, linking material degradation mechanisms, cell engineering parameters, and module/pack assembly. It emphasizes that understanding intrinsic material stability and establishing coordinated engineering control across hierarchical levels are vital for preventing degradation coupling ...

Serum PFAS in Aircraft Rescue and Firefighting (ARFF) Firefighters From Six U.S. Airport Fire Departments

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Use of aqueous film‐forming foam (AFFF) is a source of exposure to per‐ and polyfluoroalkyl substances (PFAS) for firefighters working in aircraft rescue and firefighting (ARFF) settings. However, data characterizing the association between serum PFAS concentrations and exposure risk factors for ARFF firefighters are limited ...

The Critical Role of Fractionated Urine Glycosaminoglycans in the Evaluation of Mucopolysaccharidosis Type II in Four Unrelated Families

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Since 2015, Ann and Robert H. Lurie Children's Hospital has performed diagnostic testing for infants who screen positive for mucopolysaccharidosis type II (MPS II) on the Illinois newborn screen. Preliminary diagnostic testing includes measurement of plasma iduronate‐2‐sulfatase enzyme activity and urinary glycosaminoglycan analysis, followed ...
