Located in the outermost layers, the primary structures and components responsible for the skin’s barrier function are susceptible to environmental variables, dermatological conditions, and the aging process. The ensuing alterations to structure, composition, and organizational attributes of the epidermal barrier can impact its integrity and functionality. The aim of this study was to assess the effect of a novel complex composed of a ceramide, energizing peptide, and Camu Camu extract (SUPCERAT<sup>TM</sup> complex) on specific markers of epidermal barrier integrity, as well as epidermal and dermal function. All the experiments were conducted on fresh human abdominal skin explants. Intradermal production of hyaluronic acid, epidermal claudin-1, and ceramide synthase 3 expressions, as well as epidermal lipids content were assessed using specific fluorescent stainings on ex vivo skin after the application of the complex or placebo. Additionally, dermal elastase and collagenase activities were assessed using in tubo enzymatic assays. Lastly, the effect of a cosmetic cream containing SUPCERAT<sup>TM</sup> complex was assessed using subjective Global Aesthetic Improvement Scale (GAIS) in a small cohort of patients after 60 days of use. The application of the SUPCERAT<sup>TM</sup> complex on ex vivo skin led to significant increase in dermal hyaluronic acid content and epidermal activity of claudin-1, ceramide synthase 3 and epidermal ceramide content. Furthermore, in tubo enzymatic assays demonstrated inhibition of both dermal elastase and collagenase activities. In addition, the patient-reported results indicated significant improvements in skin quality and appearance. .展开更多

The effects of operational conditions of the cloud point extraction(CPE) on the polyphenol recovery and volumetric ratio were investigated. The results showed a maximum recovery of 95.71% that was obtained using 7.0 wt% Triton X-114, native pH(3.25), and 80 wt%polyphenol extract at 30 °C. The use of cloud point extraction was successful to recover the polyphenols from agroindustrial residue since it is a simple as well as of low-cost technique.展开更多

The patient was reported to have taken a spoon of a preparation containing camu-camu (myrciaria dubia) a day. He took no other drugs and did not drink alcohol or use illicit substance. Laboratory studies reveiled an elevated aspartate transaminase of 403 U/L, and alanine transaminase of 1185 U/L, alkalinephosphatase of 335 U/L, gamma glutamyl transpeptidase of 300 U/L, and elevated total bilirubin of 142 μmol/L. His complete blood count was normal. Tests for viral, metabolic or autoimmune causes of liver injury were negative. Liver biopsy demonstrated centrilobular hepatocellular damage was compatible with drug toxicity which was not of very recent origin. Clinical and laboratory signs of liver injury gradually improved and the patient was discharged. Myrciaria dubia is used as a dietary supplement with antioxidant properties. To our knowledge, this is the first report of liver injury probably related to use of camu-camu. Exclusion of other causes and the histological diagnosis were compatible with drug toxicity render camu-camu which was most likely as the cause of acute heaptitis most likely. It is important to increase the awareness of both clinicians and patients about the potential dangers of herbal remedies in absence of reliable studies of clinical efficacy and benefit-risk assessment.展开更多
