Dead Sea Water (DSW) is well known for its dermatological benefits and has been widely used in dermatological therapy and skin care for conditions such as psoriasis, atopic dermatitis and photoaging. However, the anti-aging and rejuvenating effects of DSW and the related biological pathways involved, which have attracted increasing attention, are not fully understood. The aim of this study is to investigate the anti-aging and rejuvenating effects of DSW and to explore the related potential biological mechanisms of DSW under different environmental conditions.
- Methods : The effects of DSW were investigated using in vitro human dermal cells and reconstructed skin models. Extracellular matrix (ECM) components and the morphological changes at the dermal-epidermal junction (DEJ) in a 3D human skin model were evaluated after DSW treatment. RNA sequencing (RNA-seq) analysis of human dermal fibroblast models after DSW treatment was performed to explore the potential mechanisms of action of DSW under normal and UV stress conditions.
- Results : The novel findings in this work present the biological functions of DSW, including procollagen-1 and elastin secretion, hemidesmosome increase and the epidermal basal cell regeneration. In addition, GO, KEGG and Reactome analyses reveal the activation of pathways related to ion transmembrane transporter activity, ECM component biosynthesis, senescence-associated secretory phenotype (SASP), DNA repair and autophagy, which are associated with the anti-aging activities of DSW.
- Conclusion : Our work provides new perspectives for understanding the anti-aging and rejuvenating effects and mechanisms of DSW. The new findings also provide a theoretical basis for the further development of age-related strategies.Note de contenu : - MATERIALS AND METHODS : Normal human dermal fibroblasts (NHDFs) culture and cell viability assay - Determination of procollagen-1 and elastin in NHDFs 3D reconstructed full-thickness skin models culture Transmission electron microscope (TEM) - Immunohistochemistry (IHC) assay - Library construction and RNA sequencing of NHDFs under normal and UV conditions - Differentially expressed genes (DEGs) and pathway analysis - Statistical analysis

Peau -- Soins et hygièneTags : Anti-ageing 'Areca catechu' 'Elastase hyaluronidase' 'Phenolic substance' Index. décimale : 668.5 Parfums et cosmétiques Résumé : Nous avons au préalable testé les capacités d'inhibition de l'élastase de 150 plantes médicinales, et nous avons observé les effets inhibiteurs significatifs des extraits de Areca catechu L. sur le vieillissement et l'inflammation des tissus dermiques. Pour isoler et identifier les composés présentant une activité biologique, ils ont été purifiés par partage entre solvants, par chromatographie sur colonne de gel de silice, par CCM préparative et par HPLC en phase inverse. Les pics en HPLC coïncidant avec l'activité inhibitrice vis-à -vis de l'élastase ont été identifiés comme ceux d'une substance phénolique en utilisant diverses méthodes de colorimétrie, d'UV et d'IR. Les valeurs d'IC50 de cette substance phénolique sont de 26.9 µg.mL-1 pour l'élastase pancréatique porcine (PPE) et de 60.8 µg.mL-1 pour l'élastase neutrophile humaine (HNE). Cette substance phénolique présente une activité plus puissante que celle des composés de référence, l'acide oléanolique (76.5 µg.mL-1 pour la PPE, 219.2 µg.mL-1 pour la HNE) et l'acide ursolique (31.0 µg.mL-1 pour la PPE et 118.6 µg.mL-1 pour la HNE). D'après les tracés de Lineweaver-Burk, l'inhibition aussi bien vis-à -vis de la PPE que de la HNE par cette substance phénolique se produit par inhibition compétitive avec le substrat. La substance phénolique de A. catechu inhibe efficacement l'activité de la hyaluronidase (IC50 : 210 µg.mL-1).
Ces résultats suggèrent que la substance phénolique purifiée provenant de A. catechu montre un effet anti-vieillissement par protection des protéines des tissus connectifs.DOI : 10.1046/j.0412-5463.2001.00102.x En ligne : https://onlinelibrary.wiley.com/doi/10.1046/j.0412-5463.2001.00102.x Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=4836

Protection cutanéeIndex. décimale : 668.5 Parfums et cosmétiques Résumé : When the whole 'anti-pollution' trend ignited a couple of years ago, we could have been forgiven for wondering if it might corne and go. The reason being, targeting skin and hair damage caused by daily pollution was something many active ingredient producers focused on as far back as the late 1990s. At the time consumers did not really buy into the concept, or perhaps it was the case that brands did not convey the key messages particularly effectively.
In 2016 and 2017, 'anti-pollution' has certainly featured heavily as a trend in personal care consumer product launches, and it is a trend that is not going away any time soon. Consumer understanding and appreciation of the impact of daily pollution, and indeed différent sources of pollution (UV, Infrared light, PM2.5 and Oust, car fumes etc.), on skin and hair has increased dramatically. Ma instream and social media attention of course help to spread key messages. From a consumer product perspective, 'anti-pollution' as a trend is not exclusive to personal care, we are seeing new household electrical appliances for instance making claims about how they help to lower health damage from indoor pollution within the home.En ligne : https://drive.google.com/file/d/1uM9FsjhuXfBFG2rvPd8msG68dVFLy6aP/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28735

Toxicologie cellulaireIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Rice (Oryza sativa) bran waxes, the by-products of rice bran oil manufacturing, are widely used as inactive components in several preparations. Nevertheless, the function of rice bran waxes against skin ageing has never been reported. This study aimed to investigate thermal property and fatty acid profile of rice bran waxes, including rice bran soft (RBS) and hard (RBH) waxes, and the activities against skin ageing in cultured skin cells.
- Methods : Thermal property and fatty acid profile of rice bran waxes were analysed by differential scanning calorimetry and gas chromatography–mass spectrometry, respectively. The cytotoxicity assay of waxes was performed in B16F10 melanoma cells, human skin fibroblasts and co-culture cells of HaCaT cells and human skin fibroblasts. The non-cytotoxic concentrations of waxes were evaluated for their activities against skin ageing, including melanogenesis assay, antioxidant activity, collagen content analysis, matrix metalloproteinase-1 and matrix metalloproteinase-2 inhibitory assay and anti-inflammatory activity.
- Results : Thermal property indicated the endotherm peaks with melting temperatures at 40.89 ± 0.27°C and 69.64 ± 0.34°C for RBS and RBH, respectively. The main fatty acids in RBS were oleic (31.68 ± 0.75%) and linoleic acids (27.19 ± 0.40%), whereas those in RBH were palmitic (36.24 ± 1.08%) and stearic acids (35.21 ± 4.51%). The cytotoxicity assay in single cells and co-culture cells showed the non-cytotoxicity of RBS (0.0001–1 mg/mL) and RBH (0.0001–0.1 mg/mL). The anti-skin ageing activities of 1 mg/mL RBS and 0.1 mg/mL RBH included the melanogenesis inhibition by suppression of tyrosinase and tyrosinase-related protein-2 enzymes, the antioxidant activity by cellular protection against cell damage and cell death, the collagen stimulation, the matrix metalloproteinase-1 and matrix metalloproteinase-2 suppression and the anti-inflammation.
- Conclusions : The study results suggest that RBS and RBH can potentially be applied as the functional ingredients in formulations against skin ageing as well as provide the superior benefit on skin moisturization.Note de contenu : - MATERIALS AND METHODS : Chemicals and reagents - Analysis of thermal property - Analysis of fatty acid profile - Analysis of toxicity - Analysis of anti-skin ageing activities - Statistical analysis

GlucanesUn glucane est un polysaccharide (polymère d'oses) composé exclusivement de monomère de glucose. Ils peuvent être linéaires ou bien ramifiés.Index. décimale : 668.5 Parfums et cosmétiques Résumé : Oat beta-glucan is a water soluble, linear polymer of glucose consisting of 1,4 (70%) and 1,3 (30%) linkages with an average molecular weight of 1 × 106 Da. Scientific reports indicate beta-glucan is a film-forming moisturizer, a biological response modifier, and a promoter of wound healing. Our objective was to study the penetration of oat (1,4:1,3) beta-glucan in human skin models and to evaluate clinically its efficacy for reducing fine-lines and wrinkles. Penetration studies performed on human abdominal skin used a single application of 0.5% beta-glucan solution at a dose of 5 mg per cm2. The results showed that beta-glucan, despite its large molecular size, deeply penetrated the skin into the epidermis and dermis. A clinical study of 27 subjects was performed to evaluate the effects of beta-glucan on facial fine-lines and wrinkles. After 8 weeks of treatment, digital image analysis of silicone replicas indicated a significant reduction of wrinkle depth and height, and overall roughness.
This work is the first ex vivo and in vivo demonstration of the physiological effects of beta-glucan in the penetration and restructuring of human tissue. The study supports the use of oat beta-glucan in the care and maintenance of healthy skin and the cosmetic treatment of the signs of aging.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10463
