Tumor Implantation into the Intrahepatic Bile Duct after Percutaneous Ethanol Injection Therapy for Hepatocellular Carcinoma

open access: yesCase Reports in Gastroenterology, 2009
A 74-year-old man who had undergone transcatheter arterial embolization for hepatitis C virus-related hepatocellular carcinoma (Couinaud’s segment III/IV) in April 2003 and percutaneous ethanol injection for recurrence at the same site in February 2006 ...

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Morphology of the patent arterial duct : features relevant to treatment [PDF]

open access: yes, 2008
Patent ductus arteriosus (PDA), one of the most common congenital heart defects, is an abnormal persistence of a patent lumen in the arterial duct due to an arrest of the natural process of closure after it has served its function as a vital channel ...

Air-Sea Interaction and the Spatial Variability of the Surface Evaporation Duct in a Coastal Environment

open access: yes, 2000
Aircraft observations are presented of the horizontal variability in the depth of the surface evaporation duct and the relationship with the mesoscale structure of air-sea interaction processes. The 2-dimensional fields of near-surface wind, stress, wind-

Charge‐Reversed Lipid Nanoparticles Enable Encapsulation of Pt2L4 Nanocages for In vivo Anti‐Cancer Treatment

open access: yesAdvanced Materials, EarlyView.
Charge‐reversed lipid nanoparticles (revLNPs) enable efficient encapsulation and delivery of cationic Pt2L4 nanocages. Encapsulation preserves potent anticancer activity while improving circulation, reducing vascular leakage, and promoting favorable biodistribution in vivo.

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

open access: yesAdvanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Effect of Air-Ducted Blade Design on Horizontal Axis Wind Turbine Performance

open access: yesEnergies, 2020
Wind turbines without pitch control are more preferable from economical point of view but aerodynamic stall affects them more and after a critical wind speed local boundary layer separation occurs.

In‐House Manufacturing of 3D ECM Culture Chips via Vacuum Thermoforming for Enhanced Imaging Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Desktop vacuum thermoforming enables rapid, low‐cost fabrication of 96‐channel polystyrene culture chips with very thin imaging interfaces. The resulting platform supports cell lines, primary cells, and patient‐derived organoids, and enables high‐resolution confocal microscopy and single‐cell visualization, providing an accessible approach for advanced

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

open access: yesAdvanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in
