Automated scoring to assess RAD51-mediated homologous recombination in ovarian patient-derived tumor organoids.

PARP inhibitors (PARPi) have been shown to improve progression-free survival, particularly in homologous recombination deficient (HRD) ovarian cancers. Identifying patients eligible to PARPi is currently based on next-generation sequencing (NGS), but the persistence of genomic scars in tumors after restoration of HR or epigenetic changes can be a limitation. Functional assays could thus be used to improve this profiling and faithfully identify HRD tumors.

Many strategies enabling us to optimize kidney care may also be planet-friendly.

Kidney replacement therapy (KRT) is one of the most energy-consuming and waste-producing medical treatments. Reducing the need of dialysis is therefore an environmentally friendly choice. However, preferring prevention, lifestyle-related interventions and patient education to drugs is time consuming and most physicians are already overburdened by the many demands of routine clinical practice.

Virtual reality for reduction of intraprocedural pharmacological sedation and analgesia in adult patients: A systematic review and meta-analysis.

Background: Pharmacological sedation and analgesia are used to alleviate discomfort during awake medical procedures but can cause adverse effects like apnea and hypoxemia, increasing the need for airway management and prolonging recovery. Virtual reality (VR) has emerged as a non-pharmacological intervention to reduce the need for procedural sedatives and analgesics.

Methods: A systematic review and meta-analysis were conducted, assessing the impact of VR immersion on intraprocedural sedation and analgesia usage in adults (≥ 18 years).

Tuberculosis and people who use drugs: why focus on this overlooked population is important and why adapted interventions are necessary.

People who use drugs show a higher incidence and prevalence of tuberculosis than people who do not use drugs in areas where Mycobacterium tuberculosis is endemic. However, this population is largely neglected in national tuberculosis programmes. Strategies for active case finding, screening, and linkage to care designed for the general population are not adapted to the needs of people who use drugs, who are stigmatised and difficult to reach.

Advancing long-read nanopore genome assembly and accurate variant calling for rare disease detection.

More than 50% of families with suspected rare monogenic diseases remain unsolved after whole-genome analysis by short-read sequencing (SRS). Long-read sequencing (LRS) could help bridge this diagnostic gap by capturing variants inaccessible to SRS, facilitating long-range mapping and phasing and providing haplotype-resolved methylation profiling. To evaluate LRS's additional diagnostic yield, we sequenced a rare-disease cohort of 98 samples from 41 families, using nanopore sequencing, achieving per sample ∼36× average coverage and 32-kb read N50 from a single flow cell.

Specific Rosetta-based protein-peptide prediction protocol allows the design of novel cholinesterase inhibitor peptides.

The search for novel cholinesterase inhibitors is essential for advancing treatments for neurodegenerative disorders such as Alzheimer's disease (AD). In this study, we employed the Rosetta pepspec module, originally developed for designing peptides targeting protein-protein interactions, to design de novo peptides targeting the peripheral aromatic site (PAS) of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). A total of nine peptides were designed for human AChE (hAChE), T.

Adsorption efficiency correction for Ra determination on drinking water using Ra-Nucfilm disc.

A specific goal of the French army is to ensure health protection of soldiers consuming water from overseas operations territories. To do so, the French Defence Radiological Protection Service developed a method to quantify the amount of Ra in water using Ra-Nucfilm discs. Ra analysis is achieved within less than two days and the detection limit, function of adsorption efficiency, ranges from 0.

Hepatoblastoma in a patient with neurofibromatosis type 1: A case report.

Background: Neurofibromatosis type 1 (NF1) is one of the most common genodermatoses. It can affect every organ and is associated with an increased risk of benign and malignant tumors. Most common tumoral locations involve nervous system and soft tissues but a large variety of tumors have been described.

A conceptual mechanistic model of amino acid fluxes in the small intestine, taking the example of pig.

During digestion, almost 50% of absorbed essential amino acids (AAs) are metabolised by intestinal tissue, thus not appearing directly in the portal vein. This value, which is referred to as first-pass metabolism, seems high in relation to the overall efficiency of AA use considered in growth models. Experimental studies of first-pass metabolism are complicated due to the presence of numerous metabolic fluxes in the intestine and to the dynamics of digestion and absorption.

Public value and digital health: The example of guiding values in the national digital health strategy of France.

Introduction: In the WHO European Region, 44 of 53 reporting Member States (MS) have a national digital health strategy (NDHS) or policy. Their formulation is heterogenous and evolving and should best reflect public common interest. This research aims to explore how a public value approach improves the relevance of digital health policies and services, increasing their capacity to better serve the diverse range of societal interests.

Additional value of fetal magnetic resonance imaging for prenatal diagnosis: A retrospective study.

Objective: This study aimed to evaluate the utility of fetal MRI in prenatal diagnosis.

Enhanced mechanical properties and in vitro bioactivity of silicon nitride ceramics with SiO, YO, and AlO as sintering aids.

Silicon nitride (Si₃N₄) ceramics exhibit excellent mechanical properties and biocompatibility, making them highly suitable for biomedical applications, particularly in implants. In this study, the mechanical properties and bioactivity of Si₃N₄ ceramics with varying amounts of Y₂O₃-Al₂O₃-SiO₂ sintering aids were investigated. Increasing the sintering additive content from 4 wt% to 8 wt% substantially improved the bulk density of the ceramics, leading to notable enhancements in mechanical properties.

Electrochemical pH modulator coupled with Ni-based electrode for glucose sensing.

The non-enzymatic electrochemical detection of glucose by direct oxidation using electrodes modified with suitable electrocatalysts is now well-established. However, it most often requires highly alkaline media, limiting dramatically the use of such electrodes at neutral pH. This is notably the case of Ni-based electrodes.

Development of a novel HPLC-HRMS method for quantitative analysis of resorcinol in urine: Application to hairdressers' occupational exposure.

Resorcinol is a widespread substance used in a large variety of manufacturing industries, including cosmetics, with endocrine-disrupting activity on the thyroid function. The aim of the present study was to develop and validate a sensitive, selective and robust method to quantify resorcinol in urine and thereby assess hairdressers' occupational exposure. As resorcinol is mainly excreted in urine as glucuronide or sulfate forms, the first step consisted in hydrolyzing urine samples with a β-glucuronidase-arylsulfatase enzyme for 16 h.

Development and validation of a high-performance liquid chromatography method with fluorescence detection for the quantification of the resistance protein P-gp in cancer cells.

A method using high-performance liquid chromatography coupled with fluorescence detection (HPLC-FLD) was developed and validated to quantify the innovative tool LightSpot®-FL-1, a selective permeability-glycoprotein (P-gp)-targeted fluorescent conjugate used to measure P-gp expression in cell samples. Quantifying P-gp is a major challenge in oncology as its overexpression in many cancer cells results in Multidrug Resistance (MDR) associated with chemotherapy failure. To develop the method reported herein, both sample preparation and analysis parameters were investigated.

Understanding complex volcanic hydrosystems using a multi-tracer approach.

Climate change affects groundwater availability and residence times, necessitating a thorough understanding of aquifer characteristics to define sustainable yields, particularly in regions where water is heavily exploited. This study focuses on the Volvic volcanic aquifer (Chaîne des Puys, France), where groundwater recharge has decreased due to climate change, raising concerns about water use sustainability. To address these challenges, this work proposes a multi-tracer approach, based on hydrogeological monitoring, including the estimation of groundwater ages, major elements chemistry and water stable isotopes to better characterise this resource decrease and more peculiarly its origin and its impact on the environment that has never been addressed.
