Titre : The contribution of neurogenic inflammation to sensitive skin : concepts, mechanisms and cosmeceutical intervention Type de document : texte imprimé Auteurs : Antonio Ferrer-Montiel, Auteur ; M. Camprubi-Robles, Auteur ; Nuria Garcia-Sanz, Auteur ; Ana Sempere, Auteur ; Pierluigi Valente, Auteur ; Wim Van Den Nest, Auteur ; Cristina Carreno, Auteur Année de publication : 2009 Article en page(s) : p. 311-315 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Algogens Epidermis Immune system Nociceptor Sentitization Index. décimale : 668.5 Parfums et cosmétiques Résumé : Cutaneous neurogenic inflammation is emerging as an underlying mechanism for several skin conditions. The intimate cross-talk between the cutaneous immune system and the periperal nervous system is fundamental for skin biology. However, an imbalance or dysfunction results in the onset of an inflammatory state that is reinforced by the synergic and complementary action of both systems. Cumulative evidence indicates that the termoreceptor TRPV1 is a key player of neurogenic inflammation. This receptor is activated by both physical and chemical stimuli, and its activity is potentiated by pro-inflammatory mediators. An increase in TRPV1 activity results in an increment of neuronal excitability that leads to the release of proalgesic agents that stimulate the immune system. Therefore, the TRPV1 receptor is being considered as a cosmeceutical target, and agents that reduce its activity will be useful cosmeceuticals.

Titre : Specific repair of aging hair keratin Type de document : texte imprimé Auteurs : Erik Schulze zur Wiesche, Auteur ; Thomas Gassenmeier, Auteur ; Detlef Fischer, Auteur ; Elisabeth Poppe, Auteur ; Petra Somfleth, Auteur ; Karola Schäfer, Auteur ; Andrea Körner, Auteur Année de publication : 2009 Article en page(s) : p. 317-320 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Hair keratin strengthening Intermediate filament aging simulation restructuring Index. décimale : 668.5 Parfums et cosmétiques Résumé : A new method was developed to study aging effects onhuman hair keratin caused by shampooing, blow drying and sunlight. An automatic multiple process allowed reproducible simulation of the stress of approximately 100 Central European summer days in only 5 working days. Stress-strain measurements showed a significant weakening of the hair structure due to simulated aging effects. A new keratin active containing peptides identical to those in human hair was developed. The new keratin active penetrates deeply into the cortex cells, which was demonstrated by means of fluorescence microscopy. Aging damage was successfully prevented by strengthening the hair structure. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3259

Titre : Novel Retinol-Like Actives from Parrots Feathers Type de document : texte imprimé Année de publication : 2009 Article en page(s) : p. 323-330 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Anti-oxidant Radical stability Octatrienol Photoaging retinol-like Index. décimale : 668.5 Parfums et cosmétiques Résumé : several classes of pigments to become colourful. Melanin pigments most commonly appear in bird feathers and bare parts. They confer black, brown and chestnut hues. Carotenoids are a second group of colouring bio-chemicals in birds. These two types of pigment-based coloration are found in nearly every order of extant birds. In contrast, parrots harbour bright-coloured pigments in their feathers, which have different structures. As many coloured substances perform free-radicals scavenging action, and parrots have quite a long life-span, the aims of our study were to identify the structures of these substances, to try their synthesis, to study their performances and the possibility of use in cosmetics, while overcoming stability problems. Efficacy studies were also programmed, in order to compare them with known anti-age molecules. The main findings of our study concern the identification of a structural moiety that could create a new family of molecules with high functionality. This example could open up the field of research for new functional molecules derived from animal or vegetal metabolism, which so far have been neglected because of their high instability.
