Host‐Specific Interactions Between Staphylococcus aureus and Pseudomonas aeruginosa Impair Epithelial Repair in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is frequently associated with polymicrobial biofilms involving Staphylococcus aureus and Pseudomonas aeruginosa. Interactions between these organisms are thought to influence disease severity, but the epithelial effects of exoproteins derived from patient‐matched cocultures remain poorly defined ...

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

Angewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Identification of ticks from North of Italy by MALDI-TOF MS

Ticks and Tick-Borne Diseases
Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) has recently emerged as a promising method for arthropods identification. A total of 125 ticks collected from 2013 until 2023 in Italy either stored frozen at –20

Degradable Alternating Copolymers With Strained Cyclobutane Backbones via Photocontrolled RAFT Polymerization

Angewandte Chemie, EarlyView.
A photocontrolled RAFT strategy enables the alternating copolymerization of 1,3‐disubstituted bicyclo[1.1.0]butanes with electron‐deficient comonomers, affording well‐defined copolymers bearing strained cyclobutane backbones. A high degree of alternation, tunable molecular weights, and excellent end‐group fidelity are achieved through a CTA‐mediated ...

Glutathione‐Responsive Acyl‐Modifications for Targeted RNA Decaging and Prolonged Protein Synthesis

Angewandte Chemie, EarlyView.
The self‐immolation of disulfide‐based mRNA modifications in response to endogenous glutathione (GSH) promotes a gradual release of translatable mRNA within the cell, leading to improved nuclease resistance, tunable release properties, and a significant increase (up to 600%) of target protein production over time. This strategy offers an exciting proof

MALDI glycotyping of O-antigens from a single colony of gram-negative bacteria

Scientific Reports
Polypeptide-targeted MALDI-TOF MS for microbial species identification has revolutionized microbiology. However, no practical MALDI-TOF MS identification method for O-antigen polysaccharides, a major indicator for epidemiological classification within a ...

A Synthetic β‐Mannan Epitope Enables Immunization and Detection of Candida auris

Angewandte Chemie, EarlyView.
A synthetic β‐mannan epitope enables both active and passive immunization against Candida auris. Conjugation to the carrier protein CRM197 induces protective antibody responses, while monoclonal antibodies targeting the same epitope support detection using a lateral flow assay, linking glycochemistry with antifungal prevention and diagnostics ...

Optimization of MALDI Matrices and Their Preparation for the MALDI‐TOF MS Analysis of Oligonucleotides

Rapid Communications in Mass Spectrometry
ABSTRACT Rationale The reproducibility of the analysis of oligonucleotides using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOF MS) remains a significant challenge. This is mainly attributed to factors such as the choice and application of the matrix, as

Nitro Reduction‐Based RNA Control and Ultrafast Release

Angewandte Chemie, EarlyView.
A chemical RNA caging–uncaging strategy based on nitro reduction is described. Nitroaryl groups introduced via acylation temporarily block the functions of diverse RNAs in vitro and in living cells. Treatment with a diboronic acid–bipyridine mixture rapidly reduces the nitro groups, releasing RNAs and restoring their activity.

MALDI Matrix Research for Biopolymers

Mass Spectrometry, 2015
Matrices are necessary materials for ionizing analytes in matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS). The choice of a matrix appropriate for each analyte controls the analyses. Thus, in some cases, development or improvement of matrices can become a tool for solving problems.
