Advanced Healthcare Materials, EarlyView.The use of organ‐on‐a‐chip (OOC) microfluidic platforms is expanding in biomedical research. While this emerging technology is becoming increasingly accessible, the stability of long‐term functional cultures remains a critical challenge to address. This study presents a straightforward, one‐step method for the functionalization of polydimethylsiloxane ...

Ensemble Kalman Filters for reliability estimation in perfusion inference [PDF]
arXiv, 2018 We consider the solution of inverse problems in dynamic contrast-enhanced imaging by means of Ensemble Kalman Filters. Our quantity of interest is blood perfusion, i.e. blood flow rates in tissue. While existing approaches to compute blood perfusion parameters for given time series of radiological measurements mainly rely on deterministic ...

Advanced Healthcare Materials, EarlyView.Short‐chain fatty acids modulate anti‐ROR1 chimeric antigen receptor (CAR) T‐cell function in an intestinal adenocarcinoma‐on‐chip model. Butyrate and propionate reduce cytotoxicity, cytokine release, and infiltration by inducing a regulatory T‐cell phenotype and T‐cell exhaustion via histone deacetylase inhibition.

Advanced Healthcare Materials, EarlyView.Melanoma cell spheroid engraftment is optimized in the chicken chorioallantoic membrane overcoming the complexity of other in vivo models. Using this model, greater penetration of cerium oxide nanoparticles (nanoceria) functionalized with heparin in spheroids is observed via enhancement of vascularization than nanoceria alone.

Normothermic Perfusion is Superior to Cold Perfusion in Porcine Ex Situ Lung Perfusion
Transplantation ProceedingsCold ex situ lung perfusion (ESLP) has demonstrated improved preservation in small animal ESLP compared to normothermic ESLP and cold static preservation. We hypothesized that cold negative pressure ventilation (NPV)-ESLP would improve graft function in a porcine transplantation model.Four perfusate temperatures were examined with 12 hours NPV-ESLP in ...
