ERMP1 as a newly identified ER stress gatekeeper in chronic kidney disease.

Am J Physiol Renal Physiol

January 2025

Department of Cell Physiology and Metabolism, Faculty of Medicine, University of Geneva, Geneva, Switzerland.

ERMP1 is involved in the Unfolded Protein Response (UPR) pathway in response to endoplasmic reticulum (ER) stress. Given the pivotal role of ER stress in the pathogenesis of acute and chronic kidney diseases, we hypothesized that ERMP1 could be instrumental in the development of renal injury. analysis of RNA sequencing datasets from renal biopsies were exploited to assess the expression of ERMP1 in the kidney under normal or pathological conditions.

Stomata control plant water loss and photosynthetic carbon gain. Developing more generalized and accurate stomatal models is essential for earth system models and predicting responses under novel environmental conditions associated with global change. Plant optimality theories offer one promising approach, but most such theories assume that stomatal conductance maximizes photosynthetic net carbon assimilation subject to some cost or constraint of water.

Unlabelled: Bone is the major connective tissue maintaining the structural integrity of the human body. However, fracture and many skeletal degenerative diseases can compromise this function. Thus, therapeutics related to bone degeneration are of significant research interest and require good in vitro models for such therapeutic evaluation.

Nebulized aminoglycosides for ventilator-associated pneumonia: Methodological considerations and lessons from experimental studies.

J Intensive Med

January 2025

Department of Pneumology, Institut Clinic del Tórax, Hospital Clinic of Barcelona - Institut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), University of Barcelona - SGR 911- Ciber de Enfermedades Respiratorias (Ciberes), Barcelona, Spain.

Aminoglycosides are concentration-dependent antibiotics exerting a bactericidal effect when concentrations at the site of infection are equal to or greater than 5 times the minimum inhibitory concentrations (MIC). When administered intravenously, they exhibit poor lung penetration and high systemic renal and ototoxicity, imposing to restrict their administration to 5 days. Experimental studies conducted in anesthetized and mechanically ventilated sheep and pigs provide evidence that high doses of nebulized aminoglycosides induce a rapid and potent bacterial killing in the infected lung parenchyma.

Metabolic reprogramming in inflammaging and aging in T cells.

Life Metab

October 2023

Department of Fundamental Oncology, University of Lausanne, 1007 Lausanne, Switzerland.

Aging represents an emerging challenge for public health due to the declined immune responses against pathogens, weakened vaccination efficacy, and disturbed tissue homeostasis. Metabolic alterations in cellular and systemic levels are also known to be cardinal features of aging. Moreover, cellular metabolism has emerged to provide regulations to guide immune cell behavior via modulations on signaling cascades and epigenetic landscape, and the aberrant aging process in immune cells can lead to inflammaging, a chronic and low-grade inflammation that facilitates aging by perturbing homeostasis in tissues and organs.

Objectives: Bacille Calmette-Guérin (BCG) vaccination has off-target effects on disease risk for unrelated infections and immune responses to vaccines. This study aimed to determine the immunomodulatory effects of BCG vaccination on immune responses to vaccines against SARS-CoV-2.

Methods: Blood samples, from a subset of 275 SARS-CoV-2-naïve healthcare workers randomised to BCG vaccination (BCG group) or no BCG vaccination (Control group) in the BRACE trial, were collected before and 28 days after the primary course (two doses) of ChAdOx1-S (Oxford-AstraZeneca) or BNT162b2 (Pfizer-BioNTech) vaccination.

Pragmatic realism: towards a reconciliation of enactivism and realism.

Phenomenol Cogn Sci

February 2024

Department of Philosophy, University of Geneva, 5 rue De-Candolle, Genève, 1211 Switzerland.

This paper addresses some apparent philosophical tensions between realism and enactivism by means of Charles Peirce's pragmatism. Enactivism's Mind-Life Continuity thesis has been taken to commit it to some form of anti-realist 'world-construction' which has been considered controversial. Accordingly, a new realist enactivism is proposed by Zahidi ( (3), 461-475, 2014), drawing on Ian Hacking's 'entity realism', which places subjects in worlds comprised of the things that they can successfully manipulate.

Introduction: Novel technologies have enabled the decentralization of many aspects of clinical trials, but little research has been done on the impact of these changes on the participant experience, trial operations, or the environment.

Methods: A fully decentralized clinical trial conducted in Singapore is used as a case study to evaluate the operational outcomes, environmental impact (via life cycle assessment), and participants experience (qualitative interviews) of the decentralized model compared to a traditional study with in-person visits.

Results: The decentralized study achieved high participant retention rates (97%) and high completion rates for clinical data, even for biological samples.

Machine learning Hubbard parameters with equivariant neural networks.

NPJ Comput Mater

January 2025

Theory and Simulation of Materials (THEOS), and National Centre for Computational Design and Discovery of Novel Materials (MARVEL), École Polytechnique Fédérale de Lausanne (EPFL), Lausanne, Switzerland.

Density-functional theory with extended Hubbard functionals (DFT +  + ) provides a robust framework to accurately describe complex materials containing transition-metal or rare-earth elements. It does so by mitigating self-interaction errors inherent to semi-local functionals which are particularly pronounced in systems with partially-filled d and f electronic states. However, achieving accuracy in this approach hinges upon the accurate determination of the on-site and inter-site Hubbard parameters.

Unlabelled: The development and improvement of advanced intestinal in vitro models has received increasing attention in recent years. While the availability of relevant in vitro models is pivotal to advance the replacement and reduction of animal use in research, their robustness is a crucial determinant for intra- and interlaboratory reproducibility. We have developed a standard protocol to build a triple culture model combining two types of human intestinal epithelial cells (Caco-2, HT29-MTX-E12) and macrophages (THP-1), which was tested for transferability and reproducibility between three laboratories.

Background: As Compassionate Communities (CCs) are developing worldwide, there is a growing need to systematically assess if they are having the expected effects on the community. Although having a single strategy would be ideal in terms of standardization and comparison, due to the inherent heterogeneity of CCs, it is not known how feasible this would be.

Objectives: To assess the feasibility of creating a general strategy, based on the results of a series of focus groups conducted across three diverse CCs, to guide the evaluation of already existing programs and the development of new ones.

Evaluating the effectiveness of prompt engineering for knowledge graph question answering.

School of Engineering, Institute of Computer Science, Intelligent Information Systems Research Group, Zurich University of Applied Sciences, Winterthur, Switzerland.

Many different methods for prompting large language models have been developed since the emergence of OpenAI's ChatGPT in November 2022. In this work, we evaluate six different few-shot prompting methods. The first set of experiments evaluates three frameworks that focus on the quantity or type of shots in a prompt: a baseline method with a simple prompt and a small number of shots, random few-shot prompting with 10, 20, and 30 shots, and similarity-based few-shot prompting.

Modulation of microtubule dynamics by monovalent ions.

PNAS Nexus

January 2025

Department of Biochemistry, University of Geneva, 1211 Geneva, Switzerland.

The microtubule cytoskeleton is a dynamic network essential for many cellular processes, influenced by physicochemical factor, such as temperature, pH, dimer concentration, and ionic environment. In this study, we used in vitro reconstitution assays to examine the effects of four monovalent ions (Na, K, Cl, and Ac) on microtubule dynamics, uncovering distinct effects for each ion. Na was found to increase microtubule dynamicity by raising catastrophe frequency, polymerization and depolymerization speeds, and ultimately reducing microtubule lifetime by 80%.
