Orthotopic liver transplantation (OLT) is the only proven effective treatment for both end-stage and metabolic liver diseases. Hepatocyte transplantation is a promising alternative for OLT, but the lack of available donor livers has hampered its clinical application. Hepatocyte-like cells (HLCs) differentiated from many multi-potential stem cells can help… (More)
BACKGROUND Myofibroblastic conversion of mesothelial cells is proposed to play an important role in pathological changes following serosal membrane injury. METHODS Human peritoneal mesothelial cells (HPMCs) were isolated and maintained in culture. The gene expression was assessed by RT-PCR. Activation of signal transduction was determined by western blot… (More)
Ipomoea trifida (H.B.K.) G. Don. is the closest wild relative of cultivated sweet potato (I. batatas). The diploid I. trifida is important for sweet potato breeding and construction of transgenic systems. It can also be used to discover functional genes, particularly stress tolerance genes which had been lost during the domestication of sweet potato.… (More)
A graph X is max-λ if λ(X) = δ(X). A graph X is super-λ if X is max-λ and every minimum edge-cut set of X isolates one vertex. In this paper, we proved that for all but a few exceptions, the mixed Cayley graph which is defined as a new kind of semi-regular graph is max-λ and super-λ.
