And the stratum corneum, the outermost layer of human epidermis, plays a central role in the interaction between the cutaneous tissue and the external environment. The horny layer, and more generally the whole skin layers, avoid the penetration of harmful exogenous agents, produce molecules named anti-microbial peptides which impact the composition of the cutaneous microbiota, regulate the internal corporal temperature, avoid the water loss from the inside of the body and constitute an incredible efficient anti-oxidant network. Nevertheless, nowadays, the skin is more and more solicited by the different elements of the cutaneous exposome, including atmospheric pollution and solar radiations, which can cause a dramatic acceleration of the skin ageing process. As a consequence, due to the multifunctional protective role of the skin, during the recent decade the cosmetic industry invested massively in the development of new raw materials and end-products (dermo-cosmetics) able to preserve an optimal state of the skin regarding the external environment. Based on their physical-chemical properties thermal spring waters, which are extremely rich in inorganics ions, are interesting and powerful candidates to be part, as integral component, of new efficient dermo-cosmetic formulations dedicated to protect the skin from the external stimuli. The aim of the present work was to investigate and characterize the activity of Jonzac thermal spring water on the skin. Using different models, we proved for the first time that Jonzac thermal spring water reinforces the barrier function of the skin by modulating the expression of key markers including filaggrin and human beta defensin 2 on ex vivo human skin. The ex vivo and in vivo hydration activity, by Raman spectroscopy and corneometry respectively, has been also demonstrated. We have also shown that Jonzac thermal spring water ameliorates significantly the cutaneous microrelief in vivo. To conclude, we characterize the soothing effect of Jonzac thermal spring water by the analysis of histamine release in Substance P treated skin explants and by measuring the redness of the skin following UV exposure of the skin in vivo. We observed that both parameters decreased following a preventive treatment of the skin with Jonzac thermal spring water.

文摘Seaweed was fermented using Bifidobacterium,and its high-density fermentation conditions were investigated through single-factor experiments.The optimized fermentation conditions were determined as follows:Ulva powder as the fermentation algal body,Ulva powder addition at 2%,fermented nitrogen source as 1%soy peptone,fermentation time of 26 h,and fermentation temperature of 37℃.The Ulva powder ferment broth was subjected to the Hen’s Egg Test-Chorioallantoic Membrane(HET-CAM)assay and acute cell toxicity testing to evaluate its irritancy and safety.Additionally,cell-based experiments for firming and anti-wrinking efficacy,soothing effect,whitening potency,and antioxidant activity were conducted to assess its cosmetic functionalities.The results indicated that the obtained Ulva powder ferment broth was non-irritating and exhibited a high non-cytotoxic concentration.A 5%concentration of the Ulva powder ferment broth promoted the upregulation of Type Ⅰ collagen by 32.58%±1.33%.A 10%concentration of the ferment broth achieved relative inhibition rates of 67.64%±3.99%for nitric oxide(NO)and 55.76%±0.11%for melanin,respectively.Furthermore,a 6.25%concentration of the ferment broth demonstrated an ABTS radical scavenging rate of 58.29%±4.92%.These findings suggest that the Ulva powder ferment broth is a fermentation product characterized by high safety,excellent anti-wrinking,soothing,and whitening efficacies,along with potent in vitro antioxidant capacity.This study demonstrates its value-added development and significant potential for application in industries such as cosmetics and food.
文摘BACKGROUND Perimenopausal women are prone to anxiety and depression due to fluctuating hormone levels,which significantly impair their quality of life.The current treatments have certain limitations.In traditional Chinese medicine,liver-soothing formulas are commonly prescribed for mood-related disorders,but their overall efficacy in perimenopausal anxiety and depression remains uncertain and requires verification through meta-analysis.AIM To provide evidence-based support for clinical decision-making and research,a meta-analysis was conducted to evaluate the effectiveness of liver-soothing formulas in treating perimenopausal anxiety and depression.METHODS Relevant studies published up to April 2025 were retrieved from ClinicalTrials.gov,PubMed,Web of Science,EMBASE,and the Cochrane Library.Eligible studies were screened according to predefined inclusion and exclusion criteria.Data were extracted and analyzed using the Stata 12.0 software.RESULTS After searching and screening,12 articles involving 1798 patients(922 in the treatment group and 876 in the control group)were included in the analysis.Meta-analysis showed that the standardized scores for anxiety[standardized mean difference(SMD)=-0.71,95%confidence interval(95%CI):-1.06 to-0.36]and depression(SMD=-0.67,95%CI:-1.06 to-0.27)of the treatment group were lower than those of the control group.Subgroup analysis results revealed that for anxiety,liver-soothing formulas used alone(SMD=-0.34,95%CI:-0.50 to-0.18)or in combination(SMD=-0.88,95%CI:-1.43 to-0.34)both significantly reduced scores compared with the control group.For depression,monotherapy of liversoothing formulas showed no significant statistical difference between the treatment and control groups(SMD=-0.47,95%CI:-1.11 to 0.17),whereas combination therapy produced significantly lower standardized scale scores in the treatment group than in the control group,with a statistically significant difference(SMD=-0.83,95%CI:-1.39 to-0.28).Regarding Greene scores,no statistically significant difference was observed with monotherapy(SMD=0.87,95%CI:-0.32 to 2.06),whereas combination therapy had significantly lower Greene scores(SMD=-0.24,95%CI:-0.44 to-0.04).No statistically significant difference was found between the groups in the occurrence of adverse reactions(odds ratio=0.90,95%CI:0.57-1.43).However,liver-soothing formulas did not affect estrogen levels in perimenopausal women.CONCLUSION Compared with placebo,conventional Western medicine,or other interventions,the monotherapy of liver-soothing formulas demonstrates superior efficacy in treating perimenopausal anxiety.When used as an adjuvant,they exert a synergistic effect in alleviating negative emotions and improving overall perimenopausal symptoms.
文摘To investigate the mechanisms of apigenin(API)and proanthocyanidins(PC)in soothing sensitive skin(SS),a mast cell degranulation model was established by stimulating RBL-2H3 cells with the calcium ionophore A23187.Based on the combinatorial experiments,it was found that when API and PC were combined at the molar ratios of 4∶1 and 2∶1,they exhibited the antagonistic effects on histamine release(combination index CI>1);when they are combined at the molar ratios of 1∶1,1∶2 or 1∶4,they showed the synergistic effects on histamine release(CI<1).Among them,the combination of API and PC at a molar ratio of 1∶1 showed the better potent synergistic antihistamine release effect(CI=0.70).Histamine is a hallmark of the mast cell degranulation,consequently,the combination of API and PC at a molar ratio of 1∶1 yields the better efficiency in inhibiting the mast cell degranulation with the lowest IC_(50)value.Compared to the utilization of API or PC alone,the IC_(50)value was reduced by 11.150 and 6.503μmol/L,respectively.Compared to the positive control paeonol(PA),the treatment with the combination significantly reduced theβ-hex secretion,decreased the F-actin cytoskeleton rearrangement,and markedly suppressed the release of TNF-α,IL-4,and MCP-1.Further studies on the signaling pathways related to the mast cell degranulation indicated that the combination effectively inhibited the intracellular Ca^(2+)influx and significantly suppressed the phosphorylation of calmodulin-dependent protein kinase(CaMK)and phospholipase C/protein kinase C(PLC/PKC).In summary,the combination of API and PC at a molar ratio of 1∶1 exhibited the better synergistic antagonistic effect on the histamine release,inhibited the mast cell degranulation model activation by reducing Ca^(2+)influx and inhibiting the activation of Ca^(2+)/CaMK and PLC/PKC pathways,stabilized the cell membranes,regulated the inflammatory factor secretion,and exerted an effect in alleviating sensitive skin.
文摘Objective:When the skin is exposed to external stimuli such as ultraviolet radiation,it can lead to dryness and sensitivity,highlighting the importance of skincare.Maintaining skin homeostasis for healthy complexion requires not only controlling the inflammatory response,but also protecting the skin barrier.The study aimed to explore the potential of fermented oats(FO)as an innovative ingredient in skin care products,focusing on its capacity to alleviate inflammation and repair the skin barrier.Methods:The present study aimed to characterize the active composition and skin care effects of FO,which underwent enzymatic hydrolysis followed by fermentation with Saccharomyces cerevisiae.To evaluate the antiinflammatory properties of FO,we performed experiments to inhibit TNF-α/TNFR1 binding,nitric oxide(NO)release in RAW264.7 macrophage cells and neutrophil aggregation in zebrafish embryos.Additionally,the study evaluated the secretion of inflammatory factors,skin barrier function and moisturizing effects using a UVBirradiated skin model as a surrogate for photodamaged skin.Results:This study reveals that the fermentation process involving Saccharomyces cerevisiae significantly enhances amino acids and their derivatives in FO.Specifically,β-glucan,total protein,and flavonoids in FO increased by 14.78%,39.13%,and 600%,respectively.FO achieved a 79.87%inhibition rate of TNF-α/TNFR1 binding.It also reduced lipopolysaccharide(LPS)-induced NO release in RAW264.7 cells and inhibited neutrophil recruitment in zebrafish embryos.In a capsaicin(CAP)-stimulated skin model,3.5%FO suppressed TRPV1 expression.In a UVB-irradiated 3D skin model,FO decreased the secretion of pro-inflammatory cytokines(IL-1α,IL-6,COX2,NF-κB)and significantly upregulated loricrin(128.57%),filaggrin(336.36%),transglutaminase 1(70.97%),and caspase-14(217.65%).Additionally,FO enhanced moisturizing efficacy by increasing skin moisture content and AQP3 levels.Conclusion:As a novel fermentation ingredient,FO inhibits the expression of inflammatory factors,improves skin tissue morphology,and enhances hydration,achieving multi-faceted soothing and repairing effects.These findings suggest that Saccharomyces cerevisiae-fermented oat extracts hold promise as an innovative ingredient with anti-inflammatory and skin-protective benefits.
文摘A cytotoxicity study based on keratinocytes was carried out to determine the safe dosing concentration of plant extract formulation(hereinafter referred to as the MOSOGY).On this basis,the 3D epidermal skin model(Epikutis^(®),which is abbreviated as Epikutis later)was stimulated with anionic surfactant sodium lauryl sulfate(SLS)was used to construct an in vitro 3D epidermal skin injury model and detect the proinflammatory factor(IL-1α)after MOSOGY acted on the 3D epidermal skin model.Additionally,capsaicin(CAP)was used to stimulate the 3D epidermal skin model(EpiKutis)to detect changes in the content of transient receptor potential vanilloid 1(TRPV1)after MOSOGY treatment.The hydration levels of the stratum corneum were tested using the 3D epidermal skin model.A hyaluronidase(HAase)inhibition experiment was conducted to assess the soothing effect of BSBE.The experimental results showed that MOSOGY exhibited no significant cytotoxicity within the concentration range of 0~2.50%At a concentration of 2.00%,the inhibition rates of IL-1αand PGE2 were 15.71%and 19.00%respectively.At a concentration of 5.00%,MOSOGY exhibited inhibition rates of 43.76%for TRPV1 and 11.11%for IL-1α.MOSOGY at concentrations of 1.00%and 5.00%showed inhibition rates of 76.50%and 86.50%for HAase,respectively.The moisturizing efficacy test showed that at the concentration of 5.00%,the water content of the stratum corneum of the 3D epidermal skin model increased by 31.91%.In addition,the 3D epidermal skin model used in this experiment has the characteristics of layered structure,physiological and metabolic functions that are highly similar to natural human skin.The above research shows that MOSOGY at a certain concentration effectively inhibits IL-1α,PGE2,TRPV1 and HAase in human skin,especially the inhibition rate of HAase is more than 70.00%,indicating that BSBE have strong anti-allergic effect,and skin hydration of the 3D epidermal skin model also has a significant increase.The results indicate that MOSOGY exhibits inhibitory effects on IL-1α,PGE2,TRPV1,and HAase,achieving significant soothing and reparative effects through the inhibition of multiple targets.Additionally,it demonstrates good moisturizing efficacy and safety,making it suitable for use in cosmetics with corresponding efficacy claims.

文摘The skin is a formidable physical and biological barrier which communicates continuously with the outside of the body. And the stratum corneum, the outermost layer of human epidermis, plays a central role in the interaction between the cutaneous tissue and the external environment. The horny layer, and more generally the whole skin layers, avoid the penetration of harmful exogenous agents, produce molecules named anti-microbial peptides which impact the composition of the cutaneous microbiota, regulate the internal corporal temperature, avoid the water loss from the inside of the body and constitute an incredible efficient anti-oxidant network. Nevertheless, nowadays, the skin is more and more solicited by the different elements of the cutaneous exposome, including atmospheric pollution and solar radiations, which can cause a dramatic acceleration of the skin ageing process. As a consequence, due to the multifunctional protective role of the skin, during the recent decade the cosmetic industry invested massively in the development of new raw materials and end-products (dermo-cosmetics) able to preserve an optimal state of the skin regarding the external environment. Based on their physical-chemical properties thermal spring waters, which are extremely rich in inorganics ions, are interesting and powerful candidates to be part, as integral component, of new efficient dermo-cosmetic formulations dedicated to protect the skin from the external stimuli. The aim of the present work was to investigate and characterize the activity of Jonzac thermal spring water on the skin. Using different models, we proved for the first time that Jonzac thermal spring water reinforces the barrier function of the skin by modulating the expression of key markers including filaggrin and human beta defensin 2 on ex vivo human skin. The ex vivo and in vivo hydration activity, by Raman spectroscopy and corneometry respectively, has been also demonstrated. We have also shown that Jonzac thermal spring water ameliorates significantly the cutaneous microrelief in vivo. To conclude, we characterize the soothing effect of Jonzac thermal spring water by the analysis of histamine release in Substance P treated skin explants and by measuring the redness of the skin following UV exposure of the skin in vivo. We observed that both parameters decreased following a preventive treatment of the skin with Jonzac thermal spring water. Taken together our results indicate that Jonzac thermal spring water is a promising and powerful dermo-cosmetic which can be used to preserve an optimal state of the cutaneous tissue.
