Objectives Gadolinium-based contrast agents (GBCAs) have become an integral part in daily clinical decision making in the last 3 decades. However, there is a broad consensus that GBCAs should be exclusively used if no contrast-free magnetic resonance imaging (MRI) technique is available to reduce the amount of applied GBCAs in patients. In the current study, we investigate the possibility of predicting contrast enhancement from noncontrast multiparametric brain MRI scans using a deep-learning...

Abstract Unlike eukaryotes, prokaryotes are less proficient in homologous recombination (HR) and non-homologous end-joining (NHEJ). All existing genomic editing methods for Escherichia coli (E. coli) rely on exogenous HR or NHEJ systems to repair DNA double-strand breaks (DSBs). Although an E. coli native end-joining (ENEJ) system has been reported, its potential in genetic engineering has not yet been explored. Here, we present a CRISPR-Cas9-assisted native end-joining editing...

It's better in a melt: Copolymerization with electron‐deficient monomers in a salt melt optimizes the nucleation, local packing mode, band structure, and optical properties of carbon nitride polymers. Abstract Polymeric carbon nitride (PCN) is usually synthesized from nitrogen‐rich monomers such as cyanamide, melamine, and urea, but is rather disordered in many cases. Now, a new allotrope of carbon nitride with internal heterostructures was obtained by co‐condensation of very electron poor...

No contact with the cation: The metastable [OH(OH2)3]− anion is generated by treatment of a strongly basic phosphazene (Schwesinger base) with four equivalents of water. Thermolysis under vacuum results in the decomposition of the hydroxide salt and quantitative liberation of the free phosphazene base. This process was used to synthesize the Schwesinger base on a larger scale. Abstract The reaction of a strongly basic phosphazene (Schwesinger base) with water afforded the corresponding metastable...
