Characterization of Social Isolation and Perception of Loneliness in a Group of Chilean Older People Post-Pandemic

Published in Alzheimers & Dementia: Public Health, 2025

This study examines the impact of social isolation and perceived loneliness on self-sufficient older adults in post-pandemic Santiago, Chile. Utilizing validated scales, we analyze gender differences and correlations with psychiatric symptoms, highlighting key findings on social vulnerability and mental health.’

Antiguas placas, antiguos nombres: Crónica de un intento de memoria en las calles de Santiago

Published in Cuadernos de Beauchef Chapter: 7(2), 2024

Esta búsqueda comenzó lúdicamente, a partir de una inquietud compartida, hace diez años y en este breve periodo de tiempo podemos comprobar que hay algunas de estas placas que ya no existen y algunas de las calles han tenido otro cambio de nombre.

Cochlear dysfunction as an early biomarker of cognitive decline in normal hearing and mild hearing loss

Published in Alzheimers & Dementia: Diagnosis, Assessment & Disease Monitoring (DADM), 2024

This paper explores the connection between cochlear dysfunction and the risk of cognitive decline in older adults with normal hearing or mild hearing loss. The authors propose using otoacoustic emissions (DPOAEs) as a sensitive tool to estimate said risk. The results suggest that DPOAEs could be an early non-invasive biomarker to detect neurodegeneration and cognitive impairment in early stages.

VolumePeeler: a novel FIJI plugin for geometric tissue peeling to improve visualization and quantification of 3D image stacks

Published in BMC Bioinformatics, 2023

This paper introduces VolumePeeler, a versatile FIJI plugin designed for virtual 3D “peeling” of image stacks. The plugin incorporates spherical and spline surface projections, and we utilized it to conduct peeling on 3D images of both spherical embryos and non-spherical tissue layers. The resulting images enhance the visualization of 3D volumes, facilitating the analysis and quantification of microscopy datasets with complex geometric structures.

3D Nuclei Segmentation through Deep Learning

Published in 2023 IEEE Conference on Artificial Intelligence (CAI), 2023

This study presents a novel approach to Drosophila 3D nuclei segmentation. Our method involves a pipeline that identifies nuclei centers and segments each detected nucleus individually, employing distinct 3D U-net models for the detection and segmentation steps. Remarkably, our technique emerged as one of the top three performers in the Cell Tracking Challenge segmentation benchmark for the Light Sheet Microscopy Drosophila dataset, achieving an impressive final score of 0.827.
