Donation after circulatory death (DCD) livers face increased risks of critical complications when preserved with static cold storage (SCS). Although machine perfusion (MP) may mitigate these risks, its cost and logistical complexity limit widespread application. We developed the Dynamic Organ Storage System (DOSS), which delivers oxygenated perfusate at 10°C with minimal electrical power requirement and allows real-time effluent sampling in a portable cooler.

Background: An unmet need exists when clinically assessing retinal and layer-based features of retinal diseases. Therefore, quantification of retinal-layer-thicknesses/fluid volumes using deep-learning-augmented platforms to reproduce human-obtained clinical measurements is needed.

Methods: In this analysis, 210 spectral-domain optical coherence tomography (SD-OCT) scans (30 without pathology, 60 dry age-related macular degeneration [AMD], 60 wet AMD, and 60 diabetic macular edema [total 23,625 B-scans]) were included.

To capture the dominant interactions (surface-mediated and through-space) in catalytic hydrodeoxygenation systems, coverage-dependent mean-field models of aromatic adsorption are developed on Pt(111) and Ru(0001). We derive three key insights from this work: (1) we can universally apply mean-field models to capture the coverage-dependent behavior of oxygenated aromatics on transition-metal surfaces, (2) we can deconvolute surface-mediated and through-space interactions from the mean-field model, and (3) we can develop relatively accurate models that predict the adsorption energy of aromatics on transition-metal surfaces for the full coverage range using the work function at the lowest modeled coverage. Our approach enables the rapid prediction of the coverage-dependent behavior of oxygenated aromatics on transition-metal surfaces, reducing the computational cost associated with these studies by an order of magnitude.

Article Synopsis
  • Right heart failure is a leading cause of death in pulmonary hypertension, and lung transplants are limited due to the lack of donor lungs, highlighting the need for mechanical support for the right heart.
  • A study involved six sheep with chronic right heart failure using a wearable mechanical support system that combined a blood pump and a gas exchange unit, allowing some animals to move around freely while receiving support.
  • The system was effective, achieving similar blood flow levels to the heart and maintaining balanced blood gas levels, demonstrating potential for portable solutions in managing right heart failure.
