RAFT Copolymerization of DMAEA and AETAC Toward Charge‐Shifting Copolymers With Tunable Heparin Complexation

open access: yesMacromolecular Rapid Communications, EarlyView.
Copolymers based on charge‐shifting (DMAEA) and permanently charged (AETAC) cationic acrylates were copolymerized via the RAFT process to achieve polycations with well‐defined composition. Moderate content of AETAC did not affect hydrolysis rates but significantly enhanced heparin binding.

Impact of Monomer Purity on the Acid‐Catalyzed ROP of Sarcosine N‐Carboxyanhydrides: A Comparative Study of Phosgene‐Free Synthetic Routes toward High‐Molecular‐Weight Polysarcosine

open access: yesMacromolecular Rapid Communications, EarlyView.
A robust, phosgene‐free oxalyl chloride/silyl‐mediated route yields high‐purity sarcosine N‐carboxyanhydride (Sar‐NCA) by eliminating residual impurities that compromise polymerization control. This strategy enables well‐defined, acid‐catalyzed ring‐opening polymerization under ambient conditions, producing polysarcosine with Mn up to 186 kDa and ...

In‐frame variants in TP53 gene identified in adult leukemia samples are predominantly deleterious: a study of the TP53 Network of Education and Research Initiative on CLL

open access: yesThe Journal of Pathology, EarlyView.
Abstract The prognostic and predictive impact of TP53 variants in leukemia led to their inclusion in diagnostic and treatment guidelines, increasing the demand for rapid, reliable laboratory analysis, interpretation, and reporting. While most TP53 variants identified in tumor samples can be interpreted using data from large‐scale functional studies ...

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

Il metron della techne: apologia della diserzione

open access: yes, 2012
Moving from Roberto Marchesini’s – one of the exponent of the so called posthumanism – criticism against the dialectics “technophoby versus technomania”, this paper claims to point out and discuss the unexpressed anthropological assumption lying at the

Coupled observation‐operator approximations in outer‐loop coupling data assimilation

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We present a methodology for coupled variational data assimilation that allows the effect of coupled observation operators whilst maintaining separate minimisations across model components. This allows us to constrain the atmosphere, ocean, and sea‐ice components of our coupled model directly from satellite radiances. We illustrate the system in action
