We report the synthesis of an acyl-anchored superhydrophilic polymer (SHP) for external surface modification of liposome surface. N¹-(2-aminoethyl)-N⁴-hexadecyl-2-tetradecylsuccinamide conjugated with SHP (HDAS-SHP) was synthesized and used for modifying the liposome surface. Unlike polyethylene glycol (PEG)-phospholipids, which are commonly used for...

The presence of mixed disaccharides (maltose and isomaltose) in plasma from uremic patients has been previously investigated using gel-permeation chromatography. However, this method is unable to separate maltose (linked alpha-1-4) from isomaltose (linked alpha-1-6). We describe an alternative method using...

Circulating trimethylamine-N-oxide (TMAO) levels are strongly associated with atherosclerosis. We now examine genetic, dietary, and hormonal factors regulating TMAO levels. We demonstrate that two flavin mono-oxygenase family members, FMO1 and FMO3, oxidize trimethylamine (TMA), derived from gut flora metabolism of...

Hyperhomocysteinemia is a risk factor for atherosclerosis that is common in chronic renal failure (CRF), but its cause is unknown. Homocysteine metabolism is linked to betaine-homocysteine methyl transferase (BHMT), a zinc metalloenzyme that converts glycine betaine (GB) to N,N dimethylglycine...
