Quand le protoxyde d’azote ne fait plus rire : épidémiologie, aspects analytiques, incidences clinique et médicojudiciaire

2020

Objectifs Le 11/12/2019, le Senat adoptait la proposition de loi tendant a proteger les mineurs des usages dangereux du protoxyde d’azote (N2O). Cette utilisation n’est pas recente, son abus non plus. Neanmoins, ces dernieres annees sont marquees par un regain d’interet de son usage recreatif, notamment par une population jeune, souvent en association avec d’autres substances psychoactives. Les consequences medicales et medicolegales potentiellement graves que ce detournement peut entrainer en font actuellement une preoccupation grandissante des cliniciens et toxicologues. Il s’agit ici de faire un etat des lieux de la litterature scientifique sur le sujet. Methode Differentes sources d’inf…

Inteligencia artificial, big data y aplicaciones contra la COVID-19: privacidad y protección de datos

2020

espanolEl big data y la IA han fracasado en la prevencion, pero pueden ser muy utiles frente a la COVID-19 e incluso para evitar confinamientos y otras restricciones de derechos que provoca. La IA puede ser extremadamente eficaz para integrar, estructurar y extraer informacion y conocimiento de ingente cantidad y variedad de big data para la investigacion biomedica. Tambien es util para mejorar la atencion e informacion ciudadana y de salud, la telemedicina y la mejor asignacion de los recursos humanos y materiales. Mas amenazante para la privacidad puede ser el desarrollo de apps, pasaportes biologicos electronicos o sistemas de geolocalizacion, trazabilidad y monitoreo de personas impleme…

Anti‐Toxoplasma activity and chemical compositions of aquatic extract of Mentha pulegium L. and Rubus idaeus L.: An in vitro study

2020

Abstract This study aimed to determine the chemical compositions of crude aquatic extracts of M. pulegium L. and R. idaeus L., and their anti‐Toxoplasma activity. Crude aquatic extraction of aerial parts of R. idaeus L. and M. pulegium L. was performed. GC‐MS and HTPLC analyses were carried out. MTT assay was performed on Vero cells treated by different concentrations (Log −10 from 10−1 to 10−6) of the extracts. The anti‐Toxoplasma activity of the concentrations was investigated using vital staining. Menthol (99.23%) and limonene (0.227%) were the major compounds of the aquatic extract of M. pulegium L. Phytochemical compositions of R. idaeus L. were terpenoids, esterols, and flavonoids. Th…

Urinary 1H Nuclear Magnetic Resonance Metabolomic Fingerprinting Reveals Biomarkers of Pulse Consumption Related to Energy-Metabolism Modulation in a…

2017

Little is known about the metabolome fingerprint of pulse consumption. The study of robust and accurate biomarkers for pulse dietary assessment has great value for nutritional epidemiology regarding health benefits and their mechanisms. To characterize the fingerprinting of dietary pulses (chickpeas, lentils and beans), spot urine samples from a subcohort from the PREDIMED study were stratified, using a validated food frequency questionnaire. Non-pulse consumers (≤ 4 g/day of pulse intake) and habitual pulse consumers (≥ 25 g/day of pulse intake) were analysed using a 1H-NMR metabolomics approach combined with multi- and univariate data analysis. Pulse consumption showed differences through…

2,3-Dihydrobenzofuran privileged structures as new bioinspired lead compounds for the design of mPGES-1 inhibitors

2016

International audience; 2,3-Dihydrobenzofurans are proposed as privileged structures and used as chemical platform to design small compound libraries. By combining molecular docking calculations and experimental verification of biochemical interference, we selected some potential inhibitors of microsomal prostaglandin E2 synthase (mPGES)-1. Starting from low affinity natural product 1, by our combined approach we identified the compounds 19 and 20 with biological activity in the low micromolar range. Our data suggest that the 2,3-dihydrobenzofuran derivatives might be suitable bioinspired lead compounds for development of new generation mPGES-1 inhibitors with increased affinity.

Human limbal fibroblast-like stem cells induce immune-tolerance in autoreactive T lymphocytes from female patients with Hashimoto’s thyroiditis

2017

Background Due to their “natural immune privilege” and immunoregulatory properties human fibroblast-like limbal stem cells (f-LSCs) have acquired great interest as a potential tool for achieving immunotolerance. Hashimoto’s thyroiditis (HT) is the most common thyroid autoimmune disease and cause of hypothyroidism. To date, conventional hormone replacement therapy and unspecific immunosuppressive regimens cannot provide a definitive cure for HT subjects. We explored the immunosuppressant potential of human f-LSCs on circulating lymphomonocytes (PBMCs) collected from healthy donors and female HT patients. Methods We assessed the immunophenotyping of f-LSCs, both untreated and after 48 h of pr…

Coffee silverskin extract protects against accelerated aging caused by oxidative agents

2016

Nowadays, coffee beans are almost exclusively used for the preparation of the beverage. The sustainability of coffee production can be achieved introducing new applications for the valorization of coffee by-products. Coffee silverskin is the by-product generated during roasting, and because of its powerful antioxidant capacity, coffee silverskin aqueous extract (CSE) may be used for other applications, such as antiaging cosmetics and dermaceutics. This study aims to contribute to the coffee sector’s sustainability through the application of CSE to preserve skin health. Preclinical data regarding the antiaging properties of CSE employing human keratinocytes and Caenorhabditis elegans are col…

Neuronal inhibition of the autophagy nucleation complex extends life span in post-reproductive C. elegans

2017

Autophagy is a ubiquitous catabolic process that causes cellular bulk degradation of cytoplasmic components and is generally associated with positive effects on health and longevity. Inactivation of autophagy has been linked with detrimental effects on cells and organisms. The antagonistic pleiotropy theory postulates that some fitness-promoting genes during youth are harmful during aging. On this basis, we examined genes mediating post-reproductive longevity using an RNAi screen. From this screen, we identified 30 novel regulators of post-reproductive longevity, including pha-4. Through downstream analysis of pha-4, we identified that the inactivation of genes governing the early stages of…
