It is some 50 years since the first published reports appeared of ex vivo preservation of organs for transplantation. Over the intervening decades, organ preservation strategies have become one essential component of world-wide clinical transplant services. In the formative years, translational research in organ hypothermic preservation was grappling with the questions about whether static or dynamic storage was preferable, and the practical implications of those choices. Those studies were also informing the newly expanding clinical transplant services. During the middle years, both preservation modalities were practiced by individual group choices. By the 2000s, the shift in donor demographics demanded a re-evaluation of organ preservation strategies, and now a new era of research and development is promoting adoption of new technologies. In this review we outline many important academic studies which have contributed to this successful history, and give profile to the increasing innovative approaches which are being evaluated for the future.

Background: Creatinine-based estimated glomerular filtration rate (eGFR) equations are widely used in clinical practice but exhibit inherent limitations. On the other side, measuring GFR is time consuming and not available in routine clinical practice. We developed and validated machine learning models to assess the trustworthiness (i.

Myelomatous bone disease is a complication characterized by lytic bone lesions, reduced bone formation, bone pain, and increased fracture risk. Understanding these underlying mechanisms is crucial for developing effective therapeutic approaches. Here we show the role of enhancer of zeste homolog 2 (EZH2) in bone lesions induced by myeloma cells.

Chronic allograft rejection is mainly mediated by indirect recognition. Dendritic cells (DCs), as the major antigen-presenting cells in indirect recognition, exhibit an enhanced antigen-presenting ability in chronic rejection, but the specific mechanism is still unclear. Here, we found that pretreatment with high mobility group box-1 protein (HMGB1) in vivo can induce trained immunity in DCs.

This work aimed to evaluate whether supplementing the freezing extender with olive fruit extract (OFE) would improve the antioxidant defense of buffalo sperm, resulting in improved post-thaw semen quality. Ejaculates (two per 16 Murrah buffalo bulls) were split into four aliquots that were diluted in an extender supplemented with different doses of OFE (0, D50, D100, and D150, based on µM concentrations of hydroxytyrosol, the most represented polyphenol) and frozen according to standard procedures. At thawing, sperm motility, kinetics, viability, acrosome integrity, and membrane functionality were evaluated.

Background: Lung transplantation is the ultimate treatment option for patients with advanced cystic fibrosis. Chronic colonization of these recipients with multidrug-resistant (MDR) pathogens may constitute a risk factor for an adverse outcome. We sought to analyze whether colonization with MDR pathogens, as outlined in the German classification of multiresistant Gram-negative bacteria (MRGN), was associated with the success of lung transplantation.
