Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.Herein, a patient‐mounted neuro optical coherence tomography system that integrates a 5 degrees‐of‐freedom skull‐mounted robot (Skullbot) with a 0.6 mm neuroendoscope for targeted, minimally invasive deep brain imaging, is developed. The system offers high‐resolution imaging with precise deployment, demonstrated through successful tumor imaging in a ...

Dual‐Scale Transformer Fusion With Meta Learning for Micro Metastasis Detection in Thyroid Cancer
Advanced Intelligent Systems, EarlyView.A dual‐scale transformer model enhanced by meta‐learning enables accurate detection of tiny metastatic lesions in thyroid cancer. By combining cellular and tissue‐level features, the method outperforms existing models and shows strong adaptability to rare cases with limited data.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes
Advanced NanoBiomed Research, EarlyView.Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

Radioactivity in returned lunar materials [PDF]
The H-3, Ar-37, and Ar-39 radioactivities were measured at several depths in the large documented lunar rocks 14321 and 15555. The comparison of the Ar-37 activities from similar locations in rocks 12002, 14321, and 15555 gives direct measures of the ...

Analysis &Sensing, EarlyView.Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.
