TL;DR: In this article, an 81% absolute agreement rate was reached when assessing the phase of Aβ, i.e. phase 1, which is defined as the phase when Aβ is removed from the neocortex, phase 2, phase 3, phase 4, phase 5, and phase 6 in the cerebellum.

TL;DR: Findings suggest that autologous ASC transplantation can enhance skin graft survival in diabetic rats through differentiation, vasculogenesis, and secretion of growth factors such as VEGF and TGF-&bgr;3.

TL;DR: HIF‐1α expression may be used to refine the prognostic information provided by grade in patients with diffuse astrocytomas, and its adverse prognostic effect is most likely mediated by hypoxia, the driving force for HIF‐ 1α accumulation.
