Article Abstract
Composite polymers have become widely used in industries such as the aerospace, automobile, and civil construction industries. Continuous monitoring is essential to optimize the composite components' performance and durability. This paper describes the concept of a distributed fiber optic smart textile (DFOST) embedded into a composite panel that can be implemented during the fabrication process of bridges, planes, or vehicles without damaging the integrity of the composite. The smart textile used an embroidery method to create DFOST for easy installation between composite laminates. It also allows different layout patterns to provide two- or three-dimensional measurements. The DFOST system can then measure strain, temperature, and displacement changes, providing critical information for structural assessment. The DFOST was interrogated by using an optical frequency domain reflectometry (OFDR). It could measure strain variation during the dynamic and static test with a spatial resolution of 2 mm and a minimum strain resolution of 10 μϵ. This paper focuses on the study of strain measurement.

Background: Early diagnosis of cholangiocarcinoma (CCA) remains challenging, but liquid biopsy is emerging as a promising detection strategy. Here, we identified a novel bile biomarker for CCA and developed an optic fiber biosensor integrated with digestive endoscopy for real-time diagnosis in vivo.
Methods: A total of 583 subjects and two proteomic analyses were used to screen and validate biomarkers for CCA, and then the corresponding antibodies were generated to construct a surface plasmon resonance (SPR)-based optic fiber biosensor.

Introduction: The definition of Leber's hereditary optic neuropathy (LHON) does not take into account a preclinical phase during which the thickness of retinal nerve fiber layer (RNFL) is increased, prior to optic nerve atrophy, reducing the chances of visual recovery.
Objectives: Search for a metabolomic signature characterizing this preclinical phase and identify biomarkers predicting the risk of LHON onset.
Methods And Results: The blood and tear metabolomic profiles of 90 asymptomatic LHON mutation carriers followed for one year will be explored as a function of RNFL thickness and compared to those of a healthy control.

Fiber-optic bronchoscopy (FOB) plays a crucial role in the diagnosis and management of various pulmonary diseases by offering direct visualization of the airways and enabling targeted sampling for microbiological and histopathological evaluation. This study aimed to assess the clinical, radiological, microbiological, and histopathological profiles of patients undergoing FOB. A retrospective analysis of 103 participants who underwent the procedure over one year was conducted.
