Characterization of trehalase from Acyrthosiphon pisum for the design of new insecticides
SummaryAphids are major pests in agriculture, causing direct damage to plants and acting as vectors for phytopathogenic viruses. Conventional insecticides are widely used to control them, but their toxicity and efficacy pose problems in terms of the environment, human health and the emergence of resistance to these compounds. New alternatives are therefore needed, such as biological control using predators or parasitoids. However, these methods are not always economically viable on a large scale. As part of this thesis, another approach is being explored which involves developing new insecticides targeting the biochemical functions of aphids.The project aims to discover new inhibitors of trehalase, an enzyme essential for insect energy metabolism. Inhibition of this enzyme could disrupt vital insect functions without affecting mammals. This research involved several stages: the purification and complete characterization of trehalase from Acyrthosiphon pisum (the model for this study), the in vivo, in vitro and in silico analysis of commercial inhibitors on this enzyme, before moving on to the search for new inhibitors. Two points of integrated insect management were explored, biological and chemical control.The biological side saw the study of a strain of Streptomyces naturally producing trehalase-inhibiting metabolites, notably validamycin A, a molecule recognized in the literature as one of the best inhibitors, but not applicable as an insecticide. Other molecules appear to have interesting features, but we have not been able to isolate and characterize them.The chemical side has enabled us to create a pharmacophore hypothesis based on experimental results on molecules obtained by virtual screening. Although these molecules are not usable as insecticides as they stand, this hypothesis provides a better understanding of trehalase inhibitors in general and can be used to refine future analyses.

CHITEL 2024 - Congress of Theoretical Chemists of Latin Expression
Initiated in 1969 by Pullmann and Del Re, the congress is an annual meeting to promote collaboration and friendship between Latin-speaking theoretical chemists. In its early years, European researchers were the main contributors. Subsequently, the Latin American community has made a major contribution, with the emergence of teams whose international reputation now extends far beyond our own community.We are delighted to be holding this meeting at the University of Namur, 55 years after the first CHITEL was organised in Paris, France. We are sure that this 2024 edition will once again be an opportunity to take advantage of the good humour and dynamism of Latin to encourage, develop and strengthen scientific exchanges.We look forward to welcoming you at the University of Namur,The CHITEL 2024 Local Organising Committee.

And the light will be: Yves Caudano's ambitious goal
While still only a dream, the quantum computer is the subject of intense research. The Artemis project, funded by the European Union (EU) and involving UNamur, aims to develop new sources of single photons, and thus lay the technological foundations. A member of the project, physicist Yves Caudano hopes, at the same time, to further explore the foundations of quantum physics.

ECOBAT: Innovative materials to challenge the limitations of lithium-ion batteries
ECOBAT is an EOS project (FNRS/FWO) that brings together four universities: UCLouvain, KULeuven, the University of Bonn (Germany), and the University of Namur. This consortium currently mobilizes some twenty researchers at all levels (Masters, PhD students, post-docs, promoters), including Dr. Pierre Beaujean, under the supervision of Professor Benoît Champagne..

Is there a doctor in the village? Analysis by a sociologist
The lack of primary care is a major public health issue. In 2022, it was estimated that 52 municipalities in French-speaking Belgium were facing a severe shortage of general practitioners. This is a worrying situation that the University Observatory for Rural Medicine (OUMRu) has been addressing since 2023, with the aim of identifying concrete solutions. Working alongside a doctor and a health geographer, Amélie Pierre, a sociologist and lecturer at the Faculty of Economics, Management and Communication SciencesPo (EMCP), is studying the factors that influence access to healthcare, particularly from the patients' point of view. She emphasizes the need to take into account the realities experienced by vulnerable groups.

DCF, a molecular weapon against bacterial defenses
At a time when bacterial resistance to antibiotics is a public health problem, Professor Stéphane Vincent's team is currently developing dynamic constitutional frameworks (Dynamic Constitutional Frameworks, DCF): a molecular system that would be able to break down certain resistances and thus deliver antibiotics as close as possible to pathogens.

Citizens' assemblies: gimmicks or levers for change?
For the past fifteen years or so, participatory and deliberative democracy mechanisms have been multiplying: participatory budgets, popular consultations, citizens' panels, and so on. Vincent Jacquet, a political scientist and coordinator of the European research project Citizen Impact (ERC project, European Research Council), studies the impact of these devices from the point of view of governors and citizens.

Methods" seminar | Computational approaches to meaning change
Semantic change, i.e. the evolution of word meanings over time, offers crucial information about historical, cultural and linguistic processes. Language acts as a mirror of societal change, reflecting evolving values, norms and technological advances. Understanding how the meaning of words evolves enables us to trace these transformations and gain a deeper understanding of our distant and recent past.This seminar explores how computational methods are revolutionizing our ability to analyze semantic change in historical texts, addressing a major challenge in the field of digital humanities. While advanced computational methods enable us to analyze vast datasets and uncover previously inaccessible patterns, few natural language processing algorithms fully take into account the dynamic nature of language, particularly semantics, which is essential for research in the humanities. As AI systems develop to better understand the historical context and dynamics of language, human annotation and interpretation remain essential to capture the nuances of language and its cultural context.In this presentation, I will show how computational and human-centered approaches can be effectively combined to examine semantic change and its links to cultural and technological developments. I will present examples illustrating how semantic change can be analyzed across temporal, cultural and textual dimensions."Methods "seminarsThe Methods Seminar is a series of seminars organized at the University of Namur with the aim of fostering interdisciplinary collaboration and knowledge exchange.
