Mechanical Characterization and Computational Analysis of TPU 60A: Integrating Experimental Testing and Simulation for Performance Optimization.

This study investigates the mechanical properties of thermoplastic polyurethane (TPU) 60A, which is a flexible material that can be used to produce soft robotic grippers using additive manufacturing. Tensile tests were conducted under ISO 37 and ISO 527 standards to assess the effects of different printing orientations (0°, 45°, -45°, 90°, and quasi-isotropic) and test speeds (2 mm/min, 20 mm/min, and 200 mm/min) on the material's performance. While the printing orientations at 0° and quasi-isotropic provided similar performance, the quasi-isotropic orientation demonstrated the most balanced mechanical behavior, establishing it as the optimal choice for robust and predictable performance, particularly for computational simulations.

Assessment of orbital volume in frontofacial advancements.

Objectives: The objective of this study was to evaluate the variation of the orbital volume and the correlation with the magnitude of craniofacial advances as well as demonstrate its effectiveness through comparisons with normal levels of orbital volumes.

Introduction: Syndromic craniofacial synostosis is characterized by cranial morphological alterations and hypoplasia of the midface that may result in obstructive sleep apnea and exorbitism; these effects are indications of surgical treatment. The gradual advancement of tissues is the surgical treatment to correct accentuated exorbitisms and jaw retrusions.

Importance of early diagnosis of Stickler syndrome in newborns.

Objective: The study aims to investigate a possible correlation between the main clinical and ophthalmological characteristics, age and Robin sequence in patients with the Stickler syndrome.

Introduction: The Stickler syndrome is an autosomal dominant genetic disorder, characterised by ocular, orofacial and skeletal anomalies and/or auditory loss. Patients with Robin sequence features and respiratory complications are frequently diagnosed with the Stickler syndrome.
