Preventive nasal administration of flagellin restores antimicrobial effect of gentamicin and protects against a multidrug-resistant strain of .

The increasing prevalence of multidrug-resistant (PA) is a significant concern for chronic respiratory disease exacerbations. Host-directed drugs, such as flagellin, an agonist of toll-like receptor 5 (TLR5), have emerged as a promising solution. In this study, we evaluated the prophylactic intranasal administration of flagellin against a multidrug-resistant strain of PA (PA) in mice and assessed the possible synergy with the antibiotic gentamicin (GNT).

Poly-L-Lysine to Fight Antibiotic Resistances of .

is a major hospital-associated pathogen that can cause severe infections, most notably in patients with cystic fibrosis (CF) or those hospitalized in intensive care units. Given its remarkable ability to resist antibiotics, eradication has grown more challenging. Therefore, there is an urgent need to discover and develop new strategies that can counteract -resistant strains.

"En Face" Spectral-Domain Optical Coherence Tomography versus Multifocal Electroretinogram in Hydroxychloroquine Retinopathy Screening.

Introduction: The performance of "en face" optical coherence tomography (OCT) in screening for chloroquine (CQ) or hydroxychloroquine (HCQ) retinopathy has not been largely explored. The aim of this study was to determine the concordance of "en face" OCT with multifocal electroretinography (mfERG) in screening for CQ/HCQ retinopathy.

Foveal hypoplasia in parents of patients with albinism.

Background: Albinism is a group of genetic disorders characterized by general skin and retinal hypopigmentation. It is in most cases an autosomal recessive condition. Foveal hypoplasia (FH) is one of the main criteria for the diagnosis of albinism.

Impact of water activity on the radial growth of fungi in a dairy environment.

Filamentous fungi are used in the dairy industry as adjunct cultures in fermented products, but can also lead to food spoilage, waste and economic losses. The control of filamentous fungi with abiotic factors contributes to longer food shelf life and prevention of fungal spoilage. One of the main abiotic factors for controlling fungal growth in foods is water activity (a).

Prospective longitudinal study on prognostic factors of visual recovery and structural change after a first episode of optic neuritis.

Background And Purpose: This study was undertaken to determine the role of optical coherence tomography (OCT) in predicting the final visual and structural outcome, and to evaluate the correlation between functional eye outcome and retinal changes, in patients with a first episode of optic neuritis (ON).

Methods: In this prospective study, consecutive adult patients with acute ON underwent ophthalmological evaluation at baseline and at 1 and 12 months, including OCT measurements of peripapillary retinal nerve fiber layer (pRNFL), macular ganglion cell and inner plexiform layer, and inner nuclear layer thicknesses; high- and low-contrast visual acuity; visual field assessment; and baseline brain magnetic resonance imaging. Univariate and multivariate linear regressions were used to assess predictive factors of outcome.

Eye Involvement in Wilson's Disease: A Review of the Literature.

Wilson's disease (WD) is an autosomal recessive genetic disorder due to a mutation of the ATP7B gene, resulting in impaired hepatic copper excretion and accumulation in various tissues. Ocular findings are one of the hallmarks of the disease. Many ophthalmological manifestations have been described and new techniques are currently available to improve their diagnosis and to follow their evolution.

Host succinate inhibits influenza virus infection through succinylation and nuclear retention of the viral nucleoprotein.

Influenza virus infection causes considerable morbidity and mortality, but current therapies have limited efficacy. We hypothesized that investigating the metabolic signaling during infection may help to design innovative antiviral approaches. Using bronchoalveolar lavages of infected mice, we here demonstrate that influenza virus induces a major reprogramming of lung metabolism.

One-year outcome of neovascular age-related macular degeneration patients followed-up using different optical coherence tomography modalities.

Purpose: The aim of this study is to compare the one year outcome of neovascular age-related macular degeneration (nAMD) patients treated by a PRN regimen of Anti-vascular endothelial growth factor (VEGF) intravitreal injections (IVTs), using optical coherence tomography B-scan (OCT-B) or OCT Angiography (OCT-A) imaging modalities during follow-up.

Methods: Patients older than 50 years with nAMD currently treated by PRN regimen of Anti-VEGF IVTs were recruited from Rothschild Foundation Hospital - Paris and Centre Ophtalmologique Maison Rouge - Strasbourg and followed-up for a year. Patients were randomized in two groups: one group was followed by OCT-B while the other was followed by OCT-A.

[Long-term nursing care of the adult sickle cell patient].

Sickle cell disease is a genetic and chronic disease that requires multidisciplinary care. This requires investment on the part of both the patient and the entire health care team. In most cases, the sickle cell patient is diagnosed about two months after birth.

Molecularly Imprinted Hydrogels Selective to Ribavirin as New Drug Delivery Systems to Improve Efficiency of Antiviral Nucleoside Analogue: A Proof-of-Concept Study with Influenza A Virus.

This study describes the synthesis and evaluation of different imprinted hydrogels using ribavirin as template molecule. Ribavirin serves as a model molecule because it possesses a broad-spectrum antiviral effect against RNA viruses, which are expected as emerging viruses. The choice of monomers enables to stabilize the pre-polymerization complex and to synthesize biocompatible polymers.

Kallikrein-related peptidase 5 contributes to the remodeling and repair of bronchial epithelium.

Inflammation, oxidative stress, and protease/protease inhibitor imbalance with excessive production of proteases are factors associated with pathogenesis of the chronic obstructive pulmonary disease (COPD). In this study, we report that kallikrein-related peptidase 5 (KLK5) is a crucial protease involved in extracellular matrix (ECM) remodeling and bronchial epithelial repair after injury. First, we showed that KLK5 degrades the basal layer formed by culture of primary bronchial epithelial cells from COPD or non-COPD patients.

A Bioluminescent 3CL Activity Assay to Monitor SARS-CoV-2 Replication and Identify Inhibitors.

Our therapeutic arsenal against viruses is very limited and the current pandemic of SARS-CoV-2 highlights the critical need for effective antivirals against emerging coronaviruses. Cellular assays allowing a precise quantification of viral replication in high-throughput experimental settings are essential to the screening of chemical libraries and the selection of best antiviral chemical structures. To develop a reporting system for SARS-CoV-2 infection, we generated cell lines expressing a firefly luciferase maintained in an inactive form by a consensus cleavage site for the viral protease 3CL of coronaviruses, so that the luminescent biosensor is turned on upon 3CL expression or SARS-CoV-2 infection.
