Nasal Tuft Cell Markers Are Predictive of Overall Survival in Sinonasal Neuroendocrine and Sinonasal Undifferentiated Carcinomas

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinonasal neuroendocrine carcinoma (SNEC) and sinonasal undifferentiated carcinoma (SNUC) are rare aggressive malignancies with no established prognostic markers. Because features of POU2F3+ small cell lung carcinomas have been identified in both tumors, we evaluated immunostaining for POU2F3, a tuft cell transcription factor, and ...

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Serum Chitotriosidase Links to Activated Glia at Chronic Active Lesion Rims in Multiple Sclerosis Brain

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to explore the association between 18 kDa translocator protein (TSPO)‐positron emission tomography (PET)–measurable glial activation and serum chitotriosidase (CHIT1) in people with multiple sclerosis (pwMS), and its expression in postmortem MS brain tissue.

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

open access: yesAdvanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

Switching ATP‐Forming Phosphoryl‐Transfer Chemistry With a Restricted Set of Amino Acids

open access: yesAngewandte Chemie, EarlyView.
Constraints on amino acid composition relevant to prebiotic chemistry reshape enzyme chemistry by replacing the canonical mechanism within a conserved protein fold with a distinct ATP‐forming reaction, ADP disproportionation. Such constraints generate alternative catalytic solutions not observed in modern enzymes and point to chemically plausible early
