Spectrophotometric Analysis of Different Polymethyl Methacrylate Filters and their Importance in the Implantation of Corneal Rings.

Purpose: This study evaluated the luminous behavior applied to materials used in intraocular surgeries.

Methods: Discs of the different products were delivered in 19.00 mm × 3.

The use of the sodium fluorescein and YELLOW 560 nm filter for the resection of pediatric posterior fossa lesions.

Purpose: This study aimed to verify the feasibility, safety, and benefit of using fluorescein sodium (FL) and a YELLOW 560 nm filter in posterior fossa tumors in children.

Methods: All cases of pediatric posterior fossa tumors that have undergone surgery using fluorescein (2018-2022) have been included and were examined retrospectively. In those cases where resection of the tumor was planned, a blinded neuroradiologist distinguished gross total resection and subtotal resection according to the postoperative MRI findings.

Preoperative Assessment of Language Dominance through Combined Resting-State and Task-Based Functional Magnetic Resonance Imaging.

Brain lesions in language-related cortical areas remain a challenge in the clinical routine. In recent years, the resting-state fMRI (RS-fMRI) was shown to be a feasible method for preoperative language assessment. The aim of this study was to examine whether language-related resting-state components, which have been obtained using a data-driven independent-component-based identification algorithm, can be supportive in determining language dominance in the left or right hemisphere.

Piezoelectric 3D bioprinting for ophthalmological applications: process development and viability analysis of the technology.

Piezoelectric inkjet 3D bioprinting technology is a viable technique for ophthalmological applications. It provides versatility, high sensibility and accuracy, required in ophthalmological procedures. A process flow for biofabrication was described in detail and validated, using piezoelectric inkjet technology, for ophthalmological applications, in vitro and in situ, based on complex images.
