Abstract Synthesis and cytotoxic activities of 32 benzhydrylpiperazine derivatives with carboxamide and thioamide moieties were reported. In vitro cytotoxic activities of compounds were screened against hepatocellular (HUH-7), breast (MCF-7) and colorectal (HCT-116) cancer cell lines by sulphorhodamine B assay. In general, 4-chlorobenzhydrylpiperazine derivatives were more cytotoxic than other compounds. In ...

Recently several hierarchical access control schemes are proposed in the literature to provide security of e-medicine systems. However, most of them are either insecure against 'man-in-the-middle attack' or they require high storage and computational overheads. Wu and Chen proposed a key management method to solve dynamic access control problems in ...

Background: Induced pluripotent stem cells (iPSCs) hold promise for a new era in treating heart failure. However, the functional microstructure of iPSC-derived cardiomyocytes (iPSC-CMs) and their ability to attach to the extracellular matrix of the recipient myocardium require further elucidation. Thus, we analyzed the functional microstructure and adhesion molecules of iPSC-CM. ...

One of the lesser known clinical manifestations of Crohn's disease is the formation of small-bowel enteroliths. These concretions precipitate in the setting of small-bowel stasis within the alimentary tract and are associated with a variety of disease states causing strictures or diverticula. In the acute setting, patients typically present with ...
