A modified CO2/O2 Guedel airway improves capnographic accuracy compared with a CO2/O2 nasal cannula: An infant manikin study. [PDF]

, 2018
BACKGROUND Capnography via a CO2/O2 nasal cannula is commonly used for respiratory monitoring during sedation. However, signal disturbances are frequently encountered, especially in young children.

Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

Advanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

Advanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

VlPAG/DRN Microglia Drive Neuropathic Pain‐Induced Depression via a Defined Neuroimmune Axis

Advanced Science, EarlyView.
Peripheral nerve injury (SNI) induces neuropathic pain, activates midbrain microglia, and triggers an NLRP3–IL‐1β–dependent inflammatory cascade. IL‐1β signals through IL‐1R1 on vlPAG/DRN VGLUT2+ neurons (vlPAG/DRNGlu), inducing hyperexcitability and driving the vlPAG/DRNGlu→BNSTGABA circuit to produce the affective component of neuropathic pain ...

The effect of internal profile on cannula outflow [PDF]

, 2014
One of the medical devices used during the open heart surgery in cardiopulmonary bypass (CPB) is the aortic curve-tip cannula. The aortic curve-tip cannula is also used in the extracorporeal membrane oxygenator (ECMO) to support patient in intensive care
