As topical agents for acneic skin treatment are often irritants, dermocosmetics, may improve therapy. Thus, we developed cosmetic formulations with nicotinamide (vitamin B3), pyridoxine tris-hexyldecanoate (a vitamin B6 derivative) and zincpyrrolidone carboxylic acid (PCA) in association, and evaluated their clinical efficacy, skin compatibility, and sensory properties. The formulation (vehicle) added with vitamin B3, the vitamin B6 derivative and zinc-PCA in combination was applied twice daily for six weeks on the forehead, malar and chin skin regions of sixteen subjects. Before (pre-treatment) and after treatment, these regions were evaluated using biophysical and skin imaging techniques. Inflammatory acne lesions were reduced by 60% after application of the complete formulation. Porphyrine reduction was shown in the majority of volunteers. The results shown an improvement of inflammatory acne lesions based on porphyrine reduction, lesion counts, skin compatibility and comedogenicity testing. The skin barrier function was not impaired by the experimental formulation, which demonstrates its efficacy in acne treatment without undesirable effects. The combination of Zn-PCA and vitamins B3 and B6 vehiculated in an adequate topical formulation can be considered as a safe and effective alternative treatment for mild inflammatory acneic skin.","PeriodicalId":14771,"journal":{"name":"Journal Biomedical and Biopharmaceutical Research","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84067210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a preliminary study to identify the potential adaptations occurring in the lower limb microcirculation during loading and suspension phases of gait. Six subjects (25.8 ± 5.4) were evaluated during a protocol performed in three phases: 1 minute of both feet support, 1 minute of light steps in the same place and 1 minute similar to the initial phase. Skin microcirculation was noninvasively assessed by the Tissue Viability Imaging® System (TiVi) in both feet (expressed in AU’s). Pulse rate (PR) was measured with a photoplethysmography system (PPG). Descriptive and comparative statistics were applied, and a confidence level of 95% adopted. Our preliminary data detected a physiological variation during gait in the suspension phase of stepping, compared with the loading phase. When the foot is cyclically on the floor, the values are similar to the resting phase. Further studies are needed to look deeper into the microvascular behaviour on the lower limb during the gait cycle.","PeriodicalId":14771,"journal":{"name":"Journal Biomedical and Biopharmaceutical Research","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77585391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was also observed during massage with the contralateral limb responding similarly to the intervened limb. The present study is meant to explore this cooperation between limbs during massage, using a recently available non-contact polarized spectroscopy method. Six healthy volunteers (44.83 ± 12.64 years), both sexes, were submitted to two massage protocols applied in one random limb, using the other as control. Each protocol included three phases I rest, II massage and III recovery. Laser Doppler Flowmetry (LDF) and Tissue Viability Imager (TiVi) signals were obtained from both limbs and analyzed (p<0.05). Our results confirm previous observations where any intervention, massage included, affecting circulation in one of the lower limbs evokes a contralateral response in the non-intervened limb that seems to be part of the distal circulation regulation, affecting both limbs to maintain circulatory homeostasis.","PeriodicalId":14771,"journal":{"name":"Journal Biomedical and Biopharmaceutical Research","volume":"180 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91115453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
