Physiologic digital twins for decision support in multi-day ex vivo organ perfusion
Abstract Many potentially recoverable donor livers are discarded because current paradigms prioritize preservation and viability assessment over prolonged stabilization and rehabilitation. Multi-day normothermic ex vivo perfusion creates a therapeutic window but shifts the challenge from sustaining circulation to interpreting evolving physiologic trajectories without native homeostatic regulation.
How microrobots should be translated: A clinical and value‐centered readiness framework
1 INTRODUCTION Robotic surgery was once a futuristic idea whose time may never come; today it shapes minimally invasive care.
The Significance of Circulating Basophils as Predictors of Tumor Aggressiveness in Clear‐Cell Renal Cell Carcinoma
Our aim was to investigate the value of basophils in predicting tumor aggressiveness in clear-cell renal cell carcinoma (ccRCC). Baseline characteristics of 183 patients were recorded. Receiver operating characteristic (ROC) curve analysis was performed to calculate the cut-off value for basophil count in predicting the presence of perirenal and/or renal sinus fat involvement, as well as a high-grade WHO/ISUP score.

Elucidating the interaction dynamics between microswimmer body and immune system for medical microrobots
INTRODUCTION Untethered medical mobile robots on the size scale of a single cell can leverage minimally invasive targeted therapies at hard-to-reach, tight, and delicate body sites, such as the central nervous system, vascular system, and fetus (1–3).
Translational prospects of untethered medical microrobots
Untethered mobile microrobots have the potential to transform medicine radically. Their small size and wireless mobility can enable access to and navigation in confined, small, hard-to-reach, and sensitive inner body sites, where they can provide new ways of minimally invasive interventions and targeted diagnosis and therapy down to the cellular length scales with high precision and repeatability.
Intracellular Accumulation of Gold Nanoparticles Leads to Inhibition of Macropinocytosis to Reduce the Endoplasmic Reticulum Stress
Citrate-capped AuNPs with ca. 12?nm size (12.2?±?1.0?nm by transmission electron microscopy and 11.8?±?2.3?nm by dynamic light scattering) were synthesized by using Turkevich method (Fig. 2B and Figure S1A). The UV-Vis spectrum of citrate-capped AuNPs displayed a distinct surface plasmon resonance peak (SPR) at 518?nm (in ultrapure water).
Mobile Microrobots for Bioengineering Applications
Untethered micron-scale mobile robots can navigate and non-invasively perform specific tasks inside unprecedented and hard-to-reach inner human body sites and inside enclosed organ-on-a-chip microfluidic devices with live cells. They are aimed to operate robustly and safely in complex physiological environments where they will have a transforming impact in bioengineering and healthcare.
The amount of water in our dams has decreased
Browse Articles » Home & Family » The amount of water in our dams has decreased by Hakan Ceylan manager The amount of water in our dams has decreased Turkey is a country that suffers from water scarcity. Although the country's annual water requirement is 150 billion cubic meters, annual water collection is only 110 billion cubic meters. For this reason, dams were built to meet Turkey's water needs. Dams are used to collect rain and snow water.
