Laboratoire d’Informatique et Systèmes PhD Students Day !

We are pleased to share that Chandrasekar Subramani Narayana recently participated in the LIS (Laboratoire d’Informatique et Systèmes) PhD Students Day on June 7, 2024. He presented his work titled “Counting Phage: Decoding Antibody & Antigen Kinetics Behavior,” which focuses on the counting task in fluorescence microscopy images and count-guided localization using deep learning and computer vision.

The event offered a valuable opportunity for sharing scientific interests and knowledge while discovering the diverse range of topics being explored by other PhD students and research teams.

17th International Toxoplasmosis Conference Participation

We are excited to announce that Aurélien Dumètre and Jana El Husseiny recently attended the 17th International Toxoplasmosis Conference in Berlin, Germany. This event covered various aspects of Toxoplasma research, ranging from molecular biology to clinical disease and epidemiology.

Before the main conference, they participated in the 3rd Environmental Toxoplasmosis Meeting, co-organized by Aurélien Dumètre and other experts in the field. This meeting focused on advancing the understanding of the environmental aspects and public health implications of Toxoplasmosis. Additionally, they attended a joint session with the ToxoDB workshop, which aimed to enhance participants skills and knowledge in using the ToxoDB database for research and data analysis.

Aurélien gave a talk at the workshop titled “Eimeria acervulina, a Promising Surrogate for the Study of Toxoplasma gondii Oocyst Inactivation.” Jana showcased her PhD project at both the workshop and the conference, delivering a talk at the workshop and presenting a turbo talk and a poster on her research titled “Unraveling Morphological and Biomechanical Responses to Harsh Environmental Conditions in Coccidian Oocysts.”

We are proud of their contributions and the recognition of their work at these significant scientific gatherings.

A new article on AI Tools for Immunofluorescence-Based Diagnostics

We are excited to share our latest research published in the International Journal of Molecular Sciences: “Comparison of the Capacity of Several Machine Learning Tools to Assist Immunofluorescence-Based Detection of Anti-Neutrophil Cytoplasmic Antibodies.”

This work was conducted in collaboration with Daniel Bertin and Nathalie Bardin, both members of the Immunology Laboratory of Marseille Hospitals, and Pierre Bongrand from LAI.

This study addresses a current challenge of using artificial intelligence to perform biomedical tasks without any human intervention, which might result in lower cost, increased availability and increased rapidity. Here, we compared the capacity of several widely available machine learning tools to analyze microscopic images in order to diagnose some autoimmunity diseases. The paper described preliminary results obtained with a dataset of 1,733 cell images.

Transforming Cell Assays: Bridging Science and Hospital Needs

Annual scientific day of Aix-Marseille University Imaging Institute took place February 23rd. Laureates of the 2023 call for interdisciplinary projects presented the progress of the past year of their respective projects. Among them, a collaborative project gathering Julien Lumeau, Fabien Lemarchand, Antonin Moreau from Fresnel Institute in Marseilles and Marie-Pierre Valignat, Olivier Theodoly and Philippe Robert from LAI was presented. It focuses on coupling micropatterned cellular assays from LAI to anti-reflexive surfaces produced by Fresnel Institute to detect protein secretion by cells, to obtain marker-less, manipulation-less and real-time assays adapted to routine hospital use.
