Phosphatemia is an Independent Prognostic Factor in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to evaluate the prognostic value of several muscle damage biomarkers. Methods Data from Piemonte and Valle d'Aosta Amyotrophic Lateral Sclerosis (PARALS) were considered for this study. Survival was defined as the time from diagnosis to death, tracheostomy, or the censoring date.

New Transferrin Receptor‐Targeting Conjugate Effectively Delivers DNA to Mouse Brain

open access: yesAngewandte Chemie, EarlyView.
We present a novel RNA aptamer targeting the transferrin receptor (TfR), conjugated with DSPE lipid, which achieves remarkably efficient brain uptake, reaching brain‐to‐serum ratios as high as 6.5. Through fluorescence imaging and polymerase‐chain reaction analyses, we verify that this new conjugate successfully delivers a substantial amount of DNA ...

Ribozyme‐Catalyzed Site‐Specific Labeling of RNA Using O6‐alkylguanine SNAP‐Tag Substrates

open access: yesAngewandte Chemie, EarlyView.
SNAPR is a ribozyme that repurposes O6‐benzylguanine SNAP‐tag substrates for site‐specific labeling of RNA with bioorthogonal alkyne and azide functional groups, fluorophores or photocrosslinkers. The N1A‐alkylated RNA products were converted to N6A‐modified RNA by Dimroth rearrangement.

Roadmap to Nanomedical Applications: Nanotoxicology and In Vitro Guidelines for Lanthanide‐Doped Luminescence Nanothermometers

open access: yesAdvanced NanoBiomed Research, EarlyView.
Lanthanide‐based luminescence nanothermometry holds multifaceted potential for nanomedical applications, yet despite significant research advances, clinical translation of the engineered nanomaterials is still controversial and widely disputed. This is related to crucial nanotoxicological aspects that must be addressed at the preclinical level ...

Structural Basis for the Catalytic Mechanism of ATP‐Dependent Diazotase CmaA6

open access: yesAngewandte Chemie, EarlyView.
Several diazotases have been reported in recent years, but the detailed catalytic mechanism is unclear. From X‐ray crystallography and Cryo‐EM analysis, we obtained the structure of a diazotase CmaA6, which synthesizes 3‐diazocoumaric acid. Kinetic analysis and computational analysis indicated that CmaA6 catalyzes diazotization via an unprecedented ...
