Germanium is known to occupy tetrahedral sites by substituting silicon in germanosilicate zeolites. In this study, we present pioneering findings regarding the synthesis of zeolites with an MFI structure (GeMFI) incorporating a high germanium amount (16% Ge). Remarkably, the germanium atoms feature a slight electron deficiency with respect to GeO, and the typical coordination number of 4, as usually reported for the germanosilicate zeolites, is exceeded, giving rise to Ge dimers in a double-bridge configuration.

Background: Therapeutic outcomes for patients infected by genetically divergent HIV-1/O are not well-known due to scarce data and the lack of an appropriate comparison with patients infected by pandemic HIV-1/M. We aimed to compare the immunological and virological response to cART between HIV-1/O and HIV-1/M patients followed in France.

Methods: All naïve HIV-1/O subjects initiating cART in France in ANRS-ORIVAO study were compared to naïve HIV-1/M subjects initiating cART in ANRS-COPANA cohort.

Geriatrics Department, Fernand Widal Lariboisière University Hospital, GHU APHP.Nord, Paris, France; Paris-Cité University, Inserm U1144, Paris, France; Paris-Cité University, Inserm U1153, Paris, France.

Background: The use of cerebrospinal (CSF) biomarkers in the diagnosis of Alzheimer's disease (AD) has been gaining interest in clinical practice. Although their usefulness has been demonstrated, their potential value in older patients remains debated.

Objectives: To assess whether knowledge of the results of CSF AD biomarkers was associated with the same gain in diagnostic confidence in older adults > 80 than in younger patients.

A New Three-Hit Mouse Model of Neurodevelopmental Disorder with Cognitive Impairments and Persistent Sociability Deficits.

Brain Sci

Department of Health, Normandie Université, UNICAEN (Université de Caen Normandie), INSERM (Institut National de la Santé et de la Recherche Médicale), UMR (Unité Mixte de Recherche) 1075 COMETE, Campus 5, CYCERON, FHU (Fédération Hospitalo-Universitaire) A2M2P, CHU (Centre Hospitalo-Universitaire) Caen, 14000 Caen, France.

Background/objectives: Cognitive deficits and negative symptoms associated with schizophrenia are poorly managed by current antipsychotics. In order to develop effective treatments, refining animal models of neurodevelopmental disorders is essential.

Methods: To address their multifactorial etiology, we developed a new three-hit mouse model based on the hypoglutamatergic hypothesis of the pathology combined with early stress, offering strong construct validity.

Background: Proton therapy (PRT) is an innovative radiotherapeutic modality for the treatment of cancer with unique ballistic properties. The depth-dose distribution of a proton beam reduces exposure of healthy tissues to radiations, compared with photon-therapy (XRT). To date, only few indications for proton-therapy, like pediatric cancers, chordomas, or intra-ocular neoplasms, are reimbursed by Health systems.

Background: Medulloblastoma (MB) is one of the most prevalent embryonal malignant brain tumors. Current classification organizes these tumors into four molecular subgroups (WNT, SHH, Group 3, and Group 4 MB). Recently, a comprehensive classification has been established, identifying numerous subtypes, some of which exhibit a poor prognosis.

Are causing recurrent cystitis just ordinary uropathogenic (UPEC) strains?

Virulence

December 2025

Department of Infectious Diseases, Univ Rouen Normandie, Université de Caen Normandie, INSERM, Normandie Univ, DYNAMICURE UMR 1311, CHU Rouen, Rouen, France.

Specific determinants associated with Uropathogenic (UPEC) causing recurrent cystitis are still poorly characterized. Using strains from a previous clinical study (Vitale study, clinicaltrials.gov, identifier NCT02292160) the aims of this study were (i) to describe genomic and phenotypic traits associated with recurrence using a large collection of recurrent and paired sporadic UPEC isolates and (ii) to explore within-host genomic adaptation associated with recurrence using series of 2 to 5 sequential UPEC isolates.

For several years, our society has been experiencing an aging of the population. Concurrently, there has been an observable increase in the population of nursing homes (EHPAD). The context of a global epidemic and the public health measures implemented to address it have underscored the vulnerability of our elderly population and the need for remote consultations to ensure continuity of care.

Maintaining physical function is crucial for independent living in older adults, with gait speed being a key predictor of health outcomes. Blood biomarkers may potentially monitor older adults' mobility, yet their association with slow gait speed still needs to be explored. This study aimed to investigate the relationship between blood biomarkers and gait speed using the Midlife in the United States (MIDUS) study biomarker dataset.

Université de Caen Normandie, INSERM, Normandie Université, COMETE UMR-S 1075, GIP Cyceron, Caen, F-14000, France.

This review attempts to analyze the relationship between the vestibular system and the circadian timing system. The activity of the biological clock allows an organism to optimally perform its tasks throughout the nychtemeron. To achieve this, the biological clock is subjected to exogenous factors that entrain it to a 24h period.

  • The study aimed to analyze characteristics of healthy children with obstructive sleep apnea (OSA-I) and those with OSA and non-syndromic obesity (OSA-II) in France who were treated with CPAP or NIV in 2019.
  • Data from a national survey focused on CPAP/NIV initiation criteria, duration, age at initiation, equipment used, settings, and compliance were examined.
  • Results showed that OSA-II patients were older at initiation and treated longer than OSA-I patients, with both groups mainly using CPAP, but having similar compliance rates.

Exposure and Sensitivity of Terrestrial Vertebrates to Biological Invasions Worldwide.

Glob Chang Biol

December 2024

Université Paris-Saclay, CNRS, AgroParisTech, Ecologie Systématique et Evolution, Gif-sur-Yvette, France.

While biological invasions continue to threaten biodiversity, most of current assessments focus on the sole exposure to invasive alien species (IAS), without considering native species' response to the threat. Here, we address this gap by assessing vertebrates' vulnerability to biological invasions, combining measures of both (i) exposure to 304 identified IAS and (ii) realized sensitivity of 1600 native vertebrates to this threat. We used the IUCN Red List of Threatened Species to identify species threatened by IAS, their distribution, and the species' range characteristics of their associated IAS.
