7-Dehydrocholesterol, an immediate metabolic predecessor of cholesterol, can accumulate in tissues due to some metabolic abnormalities, causing an array of symptoms known as Smith-Lemli-Opitz syndrome. Enrichment of cellular membranes with 7-dehydrocholesterol interferes with normal cell-signaling processes, which involve interaction between

The effects of nanoparticle (NP) properties, such as size, shape and surface charge, on their efficacy and toxicity have been studied extensively. However, the effect of controlled drug release on NP efficacy and toxicity has not been thoroughly evaluated in

These studies show that single-walled carbon nanotubes (SWNTs) can be effectively modified using phospholipids. Using a simple surface modification of SWNTs, followed by deposition of 1,2-bis(10,12-tricosadiynoyl)-sn-glycero-3-phosphoethanolamine (DCPE) phosphipid, results in stable water-dispersible SWNTs with highly uniform thickness.
