An untargeted LC-MS-based metabolomics analysis was performed on a set of 30 wines classified as "Provence," "Non-Provence," and "Provence imitations.

[Frequency of incidentalomas on computed tomography scans in the hospitalised elderly].

Introduction: Incidentaloma is the result of the medical problem created by the development of imaging. Without a universal definition, incidentaloma describes any incidental finding revealed by a medical examination performed for another indication, and which will be the origin of a questioning intended to give it a clinical meaning. The frequency of incidentalomas is very variable depending on the imaging technique, the organ affected and the definition used.

Single-Cell Confinement Methods to Study Plant Cytoskeleton.

Progress in cytoskeletal research in animal systems has been accompanied by the development of single-cell systems (e.g., fibroblasts in culture).

Identification of Modulators of the Aryl Hydrocarbon Receptor and Characterization of Transcriptomic and Metabolic AhR-1 Profiles.

The Aryl hydrocarbon Receptor (AhR) is a xenobiotic sensor in vertebrates, regulating the metabolism of its own ligands. However, no ligand has been identified to date for any AhR in invertebrates. In  , the AhR ortholog, AHR-1, displays physiological functions.

FERONIA and microtubules independently contribute to mechanical integrity in the Arabidopsis shoot.

To survive, cells must constantly resist mechanical stress. In plants, this involves the reinforcement of cell walls, notably through microtubule-dependent cellulose deposition. How wall sensing might contribute to this response is unknown.

Combined grade and nuclear grade are prognosis predictors of epithelioid malignant peritoneal mesothelioma: a multi-institutional retrospective study.

Epithelioid mesothelioma is the most prevalent subtype of diffuse malignant peritoneal mesothelioma. A recently described nuclear-grading system predicted survival in patients with epithelioid malignant pleural mesothelioma. The present study was undertaken to validate this grading system in epithelioid malignant peritoneal mesothelioma (EMPM) and to compare to combined grade, including nuclear atypia, mitotic count, and tumor necrosis.

Tertiary lymphoid structures in epithelioid malignant peritoneal mesothelioma are associated with neoadjuvant chemotherapy, but not with prognosis.

Epithelioid mesothelioma is the most prevalent subtype of diffuse malignant peritoneal mesothelioma. The relationship between a strong adaptive immune response and a better prognosis in malignant solid tumors is widely known. Due to the low incidence of epithelioid malignant peritoneal mesothelioma (EMPM), very little is known about their immune micro-environment.

Endothelial S1P Signaling Counteracts Infarct Expansion in Ischemic Stroke.

Rationale: Cerebrovascular function is critical for brain health, and endogenous vascular protective pathways may provide therapeutic targets for neurological disorders. S1P (Sphingosine 1-phosphate) signaling coordinates vascular functions in other organs, and S1P (S1P receptor-1) modulators including fingolimod show promise for the treatment of ischemic and hemorrhagic stroke. However, S1P also coordinates lymphocyte trafficking, and lymphocytes are currently viewed as the principal therapeutic target for S1P modulation in stroke.

Cortical tension overrides geometrical cues to orient microtubules in confined protoplasts.

In plant cells, cortical microtubules (CMTs) generally control morphogenesis by guiding cellulose synthesis. CMT alignment has been proposed to depend on geometrical cues, with microtubules aligning with the cell long axis in silico and in vitro. Yet, CMTs are usually transverse in vivo, i.

Initial experience of pressurized intraperitoneal aerosol chemotherapy (PIPAC) in a French hyperthermic intraperitoneal chemotherapy (HIPEC) expert center.

Background: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a new intraabdominal technique to approach non-resectable peritoneal carcinomatosis (PC). PIPAC can be performed alone or alternated with systemic chemotherapy to increase tumor regression. We describe our initial experience performed in an expert hyperthermic intraperitoneal chemotherapy (HIPEC) French center to demonstrate the safety and the feasibility of PIPAC.

Acceptability of oral liquid pharmaceutical products in older adults: palatability and swallowability issues.

Background: In institutional care, oral liquid pharmaceutical products are widely prescribed for older patients, especially for those with swallowing disorders. As medicines acceptability is a key factor for compliance in the older population, this study investigated the acceptability of oral liquid pharmaceutical products in this targeted population.

Methods: An observational, multicenter, prospective study was conducted in eight geriatric hospitals and eight nursing homes in France.

Dosage form suitability in vulnerable populations: A focus on paracetamol acceptability from infants to centenarians.

Introduction: Medicine acceptability is a multi-faceted concept driven by both product and user characteristics. Although a key factor for treatment effectiveness, especially in vulnerable populations, knowledge of those medicine features that best promote individual user acceptability remains fragmented. Focusing on paracetamol, this study has explored the appropriateness of pharmaceutical products in different dosage forms to achieve adequate patient acceptability from infants to centenarians.

Outcome of children with Shiga toxin-associated haemolytic uraemic syndrome treated with eculizumab: a matched cohort study.

Background: Treatment with eculizumab in Shiga toxin-associated haemolytic and uraemic syndrome (STEC-HUS) remains controversial despite its increasing utilization. The aim of our study was to evaluate the outcomes of children treated with eculizumab for STEC-HUS in a single-centre matched cohort study.

Methods: Data were retrospectively collected from medical records of children diagnosed with STEC-HUS.

Immunosuppressive Tumor Microenvironment Status and Histological Grading of Endometrial Carcinoma.

The recent successes of new cancer immunotherapy approaches have led to investigate their relevance in the context of the Endometrial Carcinoma (EC). These therapies, that take the tumor-induced immunosuppressive microenvironment into account, target the tumor immune escape, in particular the inhibitory receptors involved in the regulation of the effector T cells' activity (immune checkpoints). The aim of this study was to identify, in ECs, differences in intergrades immune status that could contribute to the differences in tumor aggressiveness, and could also be used as theranostic tools.

Assessing the benefit of the 72-hour antibiotic therapy reassessment documentation.

Objectives: To assess the documentation of the 72-hour antibiotic therapy reassessment in medical records.

Methods: One-day prevalence evaluation of curative antibiotic therapies≥72hours. The documentation of the reassessment was defined according to three criteria: (1) "clear" documentation (clinical or microbiological comment associated with a comment on the need to adjust the antibiotic therapy or on the lack of need); (2) "tacit" documentation (only based on a clinical or microbiological comment); (3) no documentation.

A Decision Support Tool Facilitating Medicine Design for Optimal Acceptability in The Older Population.

Purpose: Medicine acceptability, which is of the utmost importance for vulnerable patients' adherence, is driven by both user and product characteristics. Herein, a novel multivariate approach integrating the many aspects of acceptability is used to discriminate positively and negatively accepted medicines in the older population.

Methods: An observational study was carried out in eight hospitals and eight nursing homes to collect a large set of real-life data on medicines uses in older patients (≥65 years).

Involvement of Aryl hydrocarbon receptor in myelination and in human nerve sheath tumorigenesis.

Aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor involved in xenobiotic metabolism. Plexiform neurofibromas (PNFs) can transform into malignant peripheral nerve sheath tumors (MPNSTs) that are resistant to existing therapies. These tumors are primarily composed of Schwann cells.

AhR-deficiency as a cause of demyelinating disease and inflammation.

The Aryl hydrocarbon Receptor(AhR) is among the most important receptors which bind pollutants; however it also regulates signaling pathways independently of such exposure. We previously demonstrated that AhR is expressed during development of the central nervous system(CNS) and that its deletion leads to the occurrence of a congenital nystagmus. Objectives of the present study are to decipher the origin of these deficits, and to identify the role of the AhR in the development of the CNS.

Papillomavirus genotyping on formaldehyde fixed paraffin-embedded tissues in vulvar intraepithelial neoplasia.

Purpose: Few studies have described the epidemiology of human papillomavirus (HPV) in vulvar intraepithelial neoplasia (VIN). The aim of this study was to genotype HPV on formalin fixed paraffin-embedded tissues in VIN lesions.

Methods: A 5-year retrospective study was conducted by including all patients attending the teaching hospital of Nice with a diagnosis of VIN between 1st January 2010 and 31st December 2014.

This study aimed at assessing the fulfillment of those recommendations and the possible impact on the liver dysfunction at supra-therapeutic doses of acetaminophen.

Methods: This study was performed one day in 9 services.

Regulation of Aquaporin 3 Expression by the AhR Pathway Is Critical to Cell Migration.

The regulation of cell migration is a key factor for the dissemination of metastatic cells during tumor progression. Aquaporins are membrane channels which allow transmembrane fluxes of water and glycerol in cells in a variety of mammalian tissues. Here, we show that AQP3, which has been incriminated in cancer progression, is regulated by the AhR, or dioxin receptor.
