Background: Lung transplantation (LuTX) can be the last resort for patients with end-stage lung diseases. In the last decades, improvements were implemented in transplant medicine, from immunosuppression throughout preservation of the donor organ to enhance lung allograft survival. This retrospective study aims to illustrate the development of the LuTX-program at the University Hospital of Munich, LMU, Munich, Germany, since its launch in 1990 by depicting and comparing postoperative outcome.

Developing the mechanism for MOF formation is crucial for the rapid development of new materials. This work demonstrates that Deuterium-NMR spectroscopy is the optimal inter-laboratory methodology for understanding the in-situ kinetics of metal-organic framework (MOF) formation. This method is facile, affordable, and allows for the isolation and monitoring of individual reagents by using one deuterated component while the remaining components are protonated.

The 1,4-relationship of the functional groups requires an Umpolung strategy as one of the α-carbonyl positions has to be inverted into an electrophilic center to react with a normal enolate. We report herein the highly enantio- and diastereoselective addition of silyl ketene acetals toward electrophilic 1-azaallyl cations to furnish chiral 4-hydrazonoesters, which are masked 1,4-dicarbonyl compounds.

We report multinuclear NMR approaches successful in the easy identification and quantification of covalently-bound functional groups on the biochar surface using P{H} CPMAS NMR spectroscopy.

Assessing the quality of such SPRs is crucial, especially within the context of a systematic review. Here, we present ECR-P (Evidence Communication Rules for Policy)-a critical appraisal tool that we have developed, which can be used in assessing not only the quality of SPRs but also the quality of their evidence base and how effectively these have both been communicated.
