Vibrational circular dichroism studies of exceptionally strong chirality inducers in liquid crystals.

2021

7,7′-Disubstituted 2,2′-methylenedioxy-1,1′-binaphthyls are highly efficient chirality inducers in nematic liquid crystals. The absolute configuration of these compounds is, however, hard to determine as they only crystallize as racemic mixtures. In this work a Vibrational Circular Dichroism (VCD) study is reported that provides an unambiguous determination of the absolute configuration of these compounds. An in-depth General Coupled Oscillator (GCO) analysis of the source of the VCD signal reveals that the unusual structure of these binaphthyl compounds inherently leads to strong and robust VCD bands. Combined with linear transit calculations, our VCD studies allow for the determination of…

Evolving Risk Factors for Mortality after Lung Transplantation over the Last 10 Years: Insights from a Single-Centre Database

2016

s S233 218 (82%) patients received pooled platelet transfusion -median (IQR) 1(1-2) U. 209 (79%) and 129 (49%) patients received fresh frozen plasma (FFP) and cryoprecipitate with a median (IQR) of 3(2-4) and 0(0-0) U respectively. Conclusion: Rate and volume of transfusion of blood products compare favourably with centres performing surgery off CPB or on ECMO. Requirement for ECMO particularly for BTT, but also PGD is associated with high transfusion requirements.
