Nicotinamide Adenine Dinucleotide (NAD+) Improves Lung Function in Rat Lung Ex-Vivo Lung Perfusion Model

Ex vivo lung perfusion in Brazil

OBJECTIVE To evaluate the use of ex vivo lung perfusion (EVLP) clinically to prepare donor lungs for transplantation. METHODS A prospective study involving EVLP for the reconditioning of extended-criteria donor lungs, the criteria for which include aspects such as a PaO2/FiO2 ratio < 300 mmHg. Between February of 2013 and February of 2014, the lungs of five donors were submitted to EVLP for u...

Comparison of lung preservation solutions in human lungs using an ex vivo lung perfusion experimental model

OBJECTIVE Experimental studies on lung preservation have always been performed using animal models. We present ex vivo lung perfusion as a new model for the study of lung preservation. Using human lungs instead of animal models may bring the results of experimental studies closer to what could be expected in clinical practice. METHOD Brain-dead donors whose lungs had been declined by transpla...

New perspectives in lung transplantation: from conventional preservation to ex vivo lung perfusion and lung reconditioning.

Inhibition of rat liver nicotinamide adenine dinucleotide kinase by reduced nicotinamide adenine dinucleotide phosphate.

Rat liver NAD kinase (ATP : NAD 2’-phosphotransferase, EC 2.7.1.23) was purified about 70-fold. The MichaelisMenten constants (Km) for NAD and ATP were 8 x 10e4 M and 2 x low3 M, respectively. NAD kinase activity was markedly inhibited by NADH and also NADPH. The Ki of NADH was approximately 1 X 10q4 M, and that of NADPH was approximately 5 X 10M5 M. Both inhibitions were competitive with NAD, ...

Ex vivo lung perfusion in clinical lung transplantation--state of the art.

Ex vivo lung perfusion (EVLP) has emerged as a new technique for assessing and potentially reconditioning human donor lungs previously unacceptable for clinical transplantation with the potential to dramatically push the limits of organ acceptability. With the recent introduction of portable EVLP, a new era in lung preservation may be upon us with the opportunity to also limit organ ischaemic t...
