Continuum Robots in Surgery: From Engineering Design to Clinical Practice

Advanced Robotics Research, EarlyView.
The hyper‐redundant nature of continuum robot structures enables near‐infinite degrees of freedom leading to immense potential for medical applications. This review provides a historical background of continuum robots and novel ideas shaping their progress to current structural design, sensing technology, modeling techniques, and control methods.

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Transition from Hepatopulmonary Syndrome to Portopulmonary Hypertension: A Case Series of 3 Patients

Case Reports in Pulmonology, 2013
Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPHTN) are the two major pulmonary vascular complications of liver disease. While HPS is characterized by low pulmonary vascular resistance, PPHTN is defined by the presence of elevated ...

Functional Disorder at the Neural Interface: How Disordered Nanostructures Promote Proper Growth and Differentiation in In Vitro Neural Cultures

Advanced Science, EarlyView.
This work provides a practical guide for neuroengineers to design advanced neural interfaces, embracing and tailoring the concept of functional disorder. By bridging 2D and 3D in vitro models, this work highlights how non‐periodic, spatially heterogeneous, multiscale nanotopography can enable more physiologically relevant platforms for studying neural ...

The correlations between luminal areas of the pulmonary arteries, the obstruction ratio and pulmonary vascular resistance.

, 2015
(A) The luminal areas of pulmonary arteries were negatively correlated with the mean obstruction ratio (n = 17, r = -0.836, p = 1.6×10−5). (B) The luminal area were negatively correlated with the follow-up pulmonary vascular resistance (PVR) (n = 16, r =

Pulmonary arterial hypertension with below threshold pulmonary vascular resistance

, 2020
Pulmonary vascular resistance (PVR) >3 Wood units is a criterion of the haemodynamic definition of pulmonary arterial hypertension (PAH). However, this cut-off is conservative and arbitrarily defined.

Changes in pulmonary arterial pressure and pulmonary vascular resistance.

, 2013
Pulmonary arterial pressure and vascular resistance rose in controls with lactic acid infusions and remained elevated throughout the study. The increase in both parameters was blunted with sabiporide. All values are the mean ± SD.
