LE STUDIUM Multidisciplinary Journal. This is the final version of the article, which has been published in final form at http://www.lestudium-ias.com/content/strategies-enhance-cosmeceuticals-vitro-cultures-herbal-plants-0; Herbal plants accumulate large amounts of phenolics and pentacyclic triterpenes. The present research project deals with the in vitro culture induction from stem and leaf explants of several medicinal plant species of Centre-Val de Loire under various plant growth regulators (PGRs) for the production of antioxidant and anti-ageing compounds. Among all the tested PGRs, auxins and cytokinins used alone or in combination induced callogenesis in stem/leaf-derived explants. Callus culture displayed feasible total phenolic content and antioxidant activity under optimum hormonal combination. HPLC analysis revealed the presence of plectranthoic acid, oleanolic acid, betulinic acid, caffeic acid and rosmarinic acid. Complete antioxidant and anti-aging potential of extracts with very contrasting phytochemical profiles were investigated. Correlation analyses revealed rosmarinic acid as the main contributor for antioxidant activity and anti-aging hyaluronidase, advance glycation end-products inhibition and SIRT1 activation, whereas, pentacyclic triterpenoids were correlated with elastase, collagenase and tyrosinase inhibition. Altogether, these results clearly evidenced the great valorization potential of herbal plants from CVL for the production of antioxidant and anti-aging bioactive extracts for cosmetic applications.

2017yCat..17929031L - publié 2014ApJ...792L..31L; Shortly after the detection of 55 Cnc e's transit was announced, we requested four spectroscopic time series on HARPS (Prog. ID 288.C-5010; PI: Triaud) as Director Discretionary Time. HARPS is installed on the 3.6 m telescope at the European Southern Observatory on La Silla, Chile (Mayor et al. 2003Msngr.114...20M). The position of 55 Cnc in the sky-RA(J2000)=08:52:35.81, DE(J2000)=+28:10:50.95-is low as seen from La Silla. The target remains at a zenith distance of z<2 for only ~2.5 hr per night, with a transit duration of about 1.5 hr having to fit within this tight window. This constraint on the airmass, essential to obtain precise radial velocities (RVs), is set by the instrumental atmospheric dispersion corrector. We used the ephemeris by Gillon et al. (2012, J/A+A/539/A28), then at an advanced stage of preparation, to schedule our observations. In total, we gathered 179 spectra on the nights starting on 2012 January 27, 2012 February 13, 2012 February 27, and 2012 March 15 UT.

2017arXiv170100366R - submitted to the European Space Agency 2017; The European Far-Infrared (FIR) Space Roadmap focuses on fundamental, yet still unresolved, astrophysical questions that can only be answered through a far-infrared space mission and gives an overview of the technology required to answer them. The document discusses topics ranging from Solar System and Planet Formation, Our Galaxy and nearby Galaxies and Distant Galaxies and Galaxy Evolution. The FIR Roadmap was open to comments from the wider astronomical community following a presentation during EWASS 2016.
