| 2 | Pros and cons of live kidney donation in prediabetics: A critical review and way forward显示文摘There is shortage of organs,including kidneys,worldwide.Along with deceased kidney transplantation,there is a significant rise in live kidney donation.The prevalence of prediabetes(PD),including impaired fasting glucose and impaired glucose tolerance,is on the rise across the globe.Transplant teams frequently come across prediabetic kidney donors for evaluation.Prediabetics are at risk of diabetes,chronic kidney disease,cardiovascular events,stroke,neuropathy,retinopathy,dementia,depression and nonalcoholic liver disease along with increased risk of all-cause mortality.Unfortunately,most of the studies done in prediabetic kidney donors are retrospective in nature and have a short follow up period.There is lack of prospective long-term studies to know about the real risk of complications after donation.Furthermore,there are variations in recommendations from various guidelines across the globe for donations in prediabetics,leading to more confusion among clinicians.This increases the responsibility of transplant teams to take appropriate decisions in the best interest of both donors and recipients.This review focuses on pathophysiological changes of PD in kidneys,potential complications of PD,other risk factors for development of type 2 diabetes,a review of guidelines for kidney donation,the potential role of diabetes risk score and calculator in kidney donors and the way forward for the evaluation and selection of prediabetic kidney donors. | Muhammad Abdul Mabood Khalil Nihal Mohammed Sadagah Jackson Tan Furrukh Omair Syed Vui Heng Chong Salem H Al-Qurashi | 2024 | World Journal of Transplantation2024，14，1： | 0 |
| 3 | Cell-derived nanovesicles from mesenchymal stem cells as extracellular vesicle-mimetics in wound healing显示文摘Wound healing is a dynamic process that involves a series of molecular and cellular events aimed at replacing devitalized and missing cellular components and/or tissue layers.Recently,extracellular vesicles(EVs),naturally cell-secreted lipid membrane-bound vesicles laden with biological cargos including proteins,lipids,and nucleic acids,have drawn wide attention due to their ability to promote wound healing and tissue regeneration.However,current exploitation of EVs as therapeutic agents is limited by their low isolation yields and tedious isolation processes.To circumvent these challenges,bioinspired cell-derived nanovesicles(CDNs)that mimic EVs were obtained by shearing mesenchymal stem cells(MSCs)through membranes with different pore sizes.Physical characterisations and highthroughput proteomics confirmed that MSC-CDNs mimicked MSC-EVs.Moreover,these MSC-CDNs were efficiently uptaken by human dermal fibroblasts and demonstrated a dose-dependent activation of MAPK signalling pathway,resulting in enhancement of cell proliferation,cell migration,secretion of growth factors and extracellular matrix proteins,which all promoted tissue regeneration.Of note,MSC-CDNs enhanced angiogenesis in human dermal microvascular endothelial cells in a 3D PEGfibrin scaffold and animal model,accelerating wound healing in vitro and in vivo.These findings suggest that MSC-CDNs could replace both whole cells and EVs in promoting wound healing and tissue regeneration. | Yub Raj Neupane Harish K.Handral Syed Abdullah Alkaff Wei Heng Chng Gopalakrishnan Venkatesan Chenyuan Huang Choon Keong Lee Jiong-Wei Wang Gopu Sriram Rhonnie Austria Dienzo Wen Feng Lu Yusuf Ali Bertrand Czarny Giorgia Pastorin | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 0 |
