Ladder-like poly(methacryloxypropyl)-silsesquioxanes (LPMASQ) are photocurable Si-based gels characterized by a double-stranded structure that ensures superior thermal stability and mechanical properties than common organic polymers. In this work, these attractive features were exploited to produce, in combination with alumina nanoparticles (NPs), both unmodified and functionalized with methacryloxypropyl-trimethoxysilane (MPTMS), LPMASQ/AlO composites displaying remarkable thermal conductivity. Additionally, we combined LPMASQ with polybutadiene (PB) to produce hybrid nanocomposites with the addition of functionalized AlO NPs.

The frontal sinus is one the most complex of the paranasal sinuses, its proximity to the cranial vault and the orbit cause that frontal sinus pathologies can progress to involve these structures and lead to significant morbidity, or even death. Surgical management of the frontal sinus is technically challenging, the most commonly used surgical approaches are coronal, butterfly, gullwing and suprabrow. The purpose of this article is to propose the C-S approach, an interesting alternative to the gullwing approach for the managing of median and paramedian frontal sinus lesions or isolated displaced fractures of the anterior wall.

The disorder is usually diagnosed in the neonatal period and the first two years of life. This anomaly has been described in association with bronchopulmonary sequestration, extralobar intra-abdominal sequestration or bronchial atresia in live and stillborn babies.
