Matériaux -- FatigueIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : In this part of the paper we try to define the influence of leather compactness in four topographic areas tested in an electron scanning microscope, namely, neck, croupon, butt and belly, on a behaviour of pigskin leather under wear conditions. Fatigue tests in the range 0-20 % extensions and apparent density tests were performed. Total compactness of the structure was defined for tested topographic areas by means of loosening ability. It was found that the butt, commonly considered to be the most compact region of pigskin, shows the highest ability to loosening (apart from belly parts) under wear conditions. Lesser ability to loosening shows neck area and the least, croupon area. The results of apparent density tests confirmed the compactness of structure defined by fatigue tests in several topographic locations.

Microbiote cutané -- AnalyseIndex. décimale : 668.5 Parfums et cosmétiques Résumé : BASF explores two new biotic active ingredients derived from the Lactobacillus crispatus bacterium.
Care products with biotic ingredients have gained enormous popularity since they are known for improving health and wellness and are associated with eco-friendliness. More specifically, consumers are seeking products that naturally target the biological ageing process of the skin. Two new biotic active ingredients derived from the Lactobacillus crispatus (LC) bacterium are supporting cosmetics manufacturers in successfully responding to this trend.Note de contenu : - Lactobacillus crispatus : a youth bacterium

EpigénétiqueL'épigénétique (mot-valise de "épigenèse" et "génétique") est la discipline de la biologie qui étudie la nature des mécanismes modifiant de manière réversible, transmissible (lors des divisions cellulaires) et adaptative l'expression des gènes sans en changer la séquence nucléotidique (ADN)
"Alors que la génétique correspond à l'étude des gènes, l'épigénétique s’intéresse à une "couche" d’informations complémentaires qui définit comment ces gènes vont être utilisés par une cellule ou… ne pas l'être".
"C'est un concept qui dément en partie la "fatalité" des gènes".

Régénération (biologie)Index. décimale : 668.5 Parfums et cosmétiques Résumé : To explore the field of epigenetics in greater detail, BASF researchers have joined forces and established an interdisciplinary innovation platform. Together with experts from public and private research institutions, they are exploring how modulations to our gene expression, caused by either chronological aging or environmental factors, can be mapped and controlled. New anti-aging active ingredients harness the platform's findings. Dermagenist®, an extract of Origanum majorana leaves, is the first active ingredient that re-activates fibroblasts by protecting them from epigenetic modifications and stimulating their vitality through LOXL1 promoter re-activation. A clinical study demonstrated an 18 % improvement in skin density after tvvo months of application, and a 15% improvement in skin firmness after three months. RNAge®, an extract of Hippophae rhamnoides seeds, fights chronological microRNA Let-7b dysregulation. Researchers has demonstrated that Let-7b is involved in epigenetic regulation and the balancing of proteins in both the extracellular matrix and the proteoglycan network required for a well-balanced dermal structure. RNAge inhibited Let-7b expression by 39 % versus the untreated control. The skin rebuilds from deep within, recovering its density (+26%) and firmness (+18.5%) for a healthy and youthful appearance.
