Regenerating the epigenome [PDF]

open access: yesThe EMBO Reports, 2011
The ability of some organisms to regenerate parts of their body has fascinated scientists for decades. The process of regeneration depends on the potential of certain cells to proliferate and contribute to the formation of new tissue. Organisms have evolved two strategies by which to achieve this: the maintenance of adult stem cells and the induction ...

Liver regeneration

open access: yesJournal of Hepatology, 2006
During liver regeneration after partial hepatectomy, normally quiescent hepatocytes undergo one or two rounds of replication to restore the liver mass by a process of compensatory hyperplasia. A large number of genes are involved in liver regeneration, but the essential circuitry required for ...

Liver regeneration [PDF]

open access: yesJournal of Cellular Physiology, 2007
AbstractLiver regeneration after partial hepatectomy is a very complex and well‐orchestrated phenomenon. It is carried out by the participation of all mature liver cell types. The process is associated with signaling cascades involving growth factors, cytokines, matrix remodeling, and several feedbacks of stimulation and inhibition of growth related ...

Improvement of technical performance of heat regenerator of GPU-3 Stirling engine

open access: yesEnergy Reports, 2023
In this paper, in order of simulate the performance of Stirling engine a novel adiabatic model (irreversible adiabatic) is proposed for the Ground Power Unit Stirling engine, which has higher accuracy than previous models of this Stirling engine.
