Exploring the Reactivity of Perphenylheptasilanes: Synthesis of Terminally Functionalized Derivatives

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Different methods to prepare 1,7‐disubstituted tetradecaphenylheptasilanes are explored. The triflated heptasilane TfO‐(SiPh2)7‐OTf reacts with alkali metal halides to produce the 1,7‐dihalogenides X‐(SiPh2)7‐X (X = F, Cl, Br, I). The 1,7‐dihydrogen derivative H‐(SiPh2)7‐H is obtained with LiAlH4 or (i‐Bu)2AlH as reducing agents.

Multimodal Assessment of Kidney Quality During 24‐h of Normothermic Machine Perfusion

open access: yesArtificial Organs, EarlyView.
Normothermic machine perfusion (NMP) has emerged as a promising tool for assessing kidney quality prior to transplantation; however, reliable biomarkers remain to be established. In this study, thirteen porcine kidneys were perfused for 24 h using an autologous leukocyte‐filtered whole blood‐based perfusate applying urine recirculation.

Delipidisation of wool fibres and the subsequent beneficial properties of delipidised wool fibres

open access: yesColoration Technology, EarlyView.
Abstract Wool fibres are complex matrices of proteins and fatty acids/lipids found both internally and externally. 18‐methyleicosanoic acid (18‐MEA) is covalently bound to the surface of the fibre via a thio‐ester link, and is considered one of the most important lipids as it is responsible for the hydrophobic properties of wool fibres.

Fatal spinal cord compression in a horse with chronic actinobacterial cranial nuchal bursitis

open access: yesEquine Veterinary Education, EarlyView.
Summary A 14‐year‐old warmblood gelding was managed for waxing and waning cranial nuchal bursitis for 2 years. Intensive medical and surgical management was not curative, and the patient was subjected to euthanasia after becoming acutely recumbent. Ante‐mortem and post‐mortem next generation sequencing of bursal tissue and post‐mortem conventional PCR ...
