BACKGROUND De novo malignancy is a leading cause of late morbidity and mortality in liver transplant *** immunosuppression has been shown to contribute to post-transplant malignancy(PTM)*** is emerging evidence on the differential carcinogenic risk profile of individual immunosuppressive drugs,independent of the net effect of *** inhibitors such as tacrolimus may promote tumourigenesis,whereas mycophenolic acid(MPA),the active metabolite of mycophenolate mofetil,may limit tumour *** transplantation(LT)is relatively unique among solid organ transplantation in that immunosuppression monotherapy with either tacrolimus or MPA is often achievable,which makes careful consideration of the risk-benefit profile of these immunosuppression agents particularly relevant for this ***,there is limited clinical data on this subject in both LT and other solid organ transplant *** To investigate the relative carcinogenicity of tacrolimus and MPA in solid organ *** A literature search was conducted using MEDLINE and Embase databases using the key terms“solid organ transplantation”,“tacrolimus”,“mycophenolic acid”,and“carcinogenicity”,in order to identify relevant articles published in English between 1st January 2002 to 11th August *** terms,synonyms and explosion of MeSH terms,Boolean operators and truncations were also utilised in the *** lists of retrieved articles were also reviewed to identify any additional *** duplicates,abstracts from 1230 records were screened by a single reviewer,whereby 31 records were reviewed in ***-text articles were assessed for eligibility based on pre-specified inclusion and exclusion *** A total of 6 studies were included in this *** studies were large population registries or cohort studies,which varied in transplant era,type of organ transplanted and immunosuppression protocol us

An environmentally friendly method using real or artificial bovine milk permeate to both depilate and preserve sheepskins has been reported which completely and cleanly removed the wool from the hair follicle and had no detrimental effects on the skin.A proteomic analysis,assessing the relative abundance of proteins in matched permeate-depilated and chemically depilated(sulfide)sheepskins,showed variations in the levels of specific collagen types in the skin's basement membrane and other proteins associated with the *** findings were corroborated by biochemical analyses of matched permeate depilated and raw skin samples,and provide clues to the mechanism of non-invasiveand complete *** also support the observation that permeate-depilated skins were smoother than their sulfide-depilated counterparts and resulted in leather with a superior surface.
