Systolic ejection murmurs and the left ventricular outflow tract in boxer dogs [PDF]

open access: yes, 2007
Turbulence of various genesis in the left ventricular outflow tract (LVOT) causes systolic ejection murmurs. The prevalence of murmurs in adult boxer dogs is 50-80%, the majority of which are of low intensity.

Low‐Temperature Remote Plasma Synthesis of Highly Porous TiO2 as Electron Transport Layers in Perovskite Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
This work presents low‐temperature (<200 °C) TiO2 electron transport layers synthesized via plasma polymerization and etching of a Ti phthalocyanine precursor. The resulting nanostructured films enhance the optical and electronic properties of halide perovskite solar cells, achieving an efficiency of 14.6%. This method provides a scalable, eco‐friendly

Radical Retention and Functional Stability of Plasma‐Polymerized Nanoparticles for Long‐Term Biofunctionalization

open access: yesAdvanced Materials Interfaces, EarlyView.
Plasma polymerized nanoparticles (PPNs) offer a solvent‐free route to functional nanocarriers with long‐lived radicals. This study establishes design principles for long‐term storage of PPNs, demonstrating that dry‐phase storage retains radical content, covalent reactivity, and bioactivity over extended periods. These findings advance the translational

Antithrombotic Therapy in Patients with Prosthetic Heart Valves [PDF]

open access: yesLibyan Journal of Medicine, 2009
Patients with mechanical valve prostheses require a lifelong anticoagulant treatment. The combined use of Warfarin and low-dose aspirin appears to reduce the risk of valve thrombosis and systemic embolism at a low risk of bleeding.

A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...
