A Framework for Emergency Department-Integrated Hepatitis C Test-and-Treat in the United States. [PDF]
J Viral HepatABSTRACT Despite the availability of curative, direct‐acting antiviral therapy, hepatitis C virus elimination remains incomplete. Losses across the care cascade continue to limit impact, from initial diagnosis to sustained virologic response. Fewer than 1/3 of individuals ultimately achieve cure. These gaps reflect a delivery system that does not align

Mesenchymal Stem Cell-Derived Apoptotic Micro-Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis. [PDF]
Adv Healthc MaterHUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

Molecular dynamics simulation of non-azeotropic refrigerants separation in auto-cascading refrigeration [PDF]
E3S Web of Conferences, 2019 The core problem of auto-cascading refrigeration is the separation of non-azeotropic refrigerants. The separation effect of mixed refrigerant directly determines the refrigeration effect of auto-cascading refrigeration system and the value of COP. The microscopic molecular dynamics simulation method is applied to the refrigeration system, and the ...
