Briefly, a bather was laid in a supine position in ceramic beads filled in a bathtab, which had been heated at around 50°C. The heated ceramic beads may radiate FIR rays, whose spectra was closely similar to those of 'black body', known to be 'perfect radiator'. Thoroughout this study, 'first-time' bathers included 31 participants. Among those, 11 individuals were further subjected to repeated sandbathing three times weekly (multi-time bathers). By re-visiting data obtained on the way of conducting that study, we re-evaluated its impacts on immunological contexts.","PeriodicalId":20060,"journal":{"name":"Photodermatology","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79224027","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 suggests that the loss of Endo180 results in the accumulation of collagen fragments in the surrounding fibroblasts and causes interference with dermal matrix remodeling via collagen fibers. The purpose of the study was to identify a mechanism by which ultraviolet B (UVB) exposure induces a loss of Endo 180 with a specific focus on the crosstalk between keratinocytes and fibroblasts.","PeriodicalId":20060,"journal":{"name":"Photodermatology","volume":"14 1","pages":"34 - 41"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73064951","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}
