Alterations in Beta Cell Identity in Type 1 and Type 2 Diabetes حسب Abu Saleh Md Moin (6189512)

"…In diabetes, (1) endocrine identity recapitulates the less mature/less-differentiated fetal/neonatal cell type, possibly representing an adaptive mechanism; (2) residual β cells may be altered in their subtype proportions or other molecular features; (3) in humans, “altered identity” is a preferable term to dedifferentiation as their cellular fate (differentiated cells losing identity or progenitors becoming more differentiated) is unclear as yet.…"

Credit bureaus and financial constraints do corruption matter? حسب Mohamed Sami Ben Ali (14152038)

"…Our findings suggest that curbing corruption creates more efficient credit bureaus that, in turn, decrease financial constraints for firms. The subsample estimations confirm these findings and show that the higher and longer-term corruption in MENA countries than in Eastern European countries make credit bureaus’ less effective, imposing more financial constraints. …"
