Dry eye disease and morphological changes in the anterior chamber in people with cystic fibrosis.

Background: Cystic fibrosis (CF) is caused by variants in a gene that encodes a protein essential for water and ion transport in the epithelial cells of exocrine organs. Given the possible relationship of this protein and conjunctival and corneal epithelium, the aim of this study was to evaluate ophthalmologic alterations in people with CF.

Methods: Forty-five people with CF underwent pulmonary evaluation including inflammatory score (IS).

Influence of the Chemical Structure of Perylene Derivatives on the Performance of Honey-Gated Organic Field-Effect Transistors (HGOFETs) and Their Application in UV Light Detection.

Electronics based on natural or degradable materials are a key requirement for next-generation devices, where sustainability, biodegradability, and resource efficiency are essential. In this context, optimizing the molecular chemical structure of organic semiconductor compounds (OSCs) used as active layers is crucial for enhancing the efficiency of these devices, making them competitive with conventional electronics. In this work, honey-gated organic field-effect transistors (HGOFETs) were fabricated using four different perylene derivative films as OSCs, and the impact of the chemical structure of these perylene derivatives on the performance of HGOFETs was investigated.

Advanced fluorescence techniques in white matter fiber visualization for neurosurgical training.

Background: Neurosurgical training requires a deep understanding of brain anatomy, especially white matter fiber pathways, to enhance surgical precision. Traditional dissection techniques, such as Klingler's white matter dissection, are essential, but newer methods can provide additional clarity. This study explores the application of a fluorescent-assisted technique to improve the visualization and understanding of white matter fibers during neurosurgical training.

Application of the Technique of Inferior Temporal Gyrus Resection for Microsurgical Treatment of Arteriovenous Malformation of the Fusiform Gyrus.

Arteriovenous malformations (AVMs) consist of multiple connections between arteries and veins without a capillary bed and are characterized by an early draining vein. This pathology affects mainly young adults, and the morbimortality is caused mostly by rupture and hemorrhage. In this Video 1, we present a case of a 29-year-old female patient presenting with a sudden severe headache.
