transfer catalysis (PTC) system. Silica nanoparticle modified by alkyl polyoxyethylene ether and tetrabutylammonium bromide (TBAB) is the highly efficient thermo-responsive Pickering emulsifier to stabilize the diisopropyl ketone-in-water emulsion. PEs can keep stable at room temperature for 3 days and demulsify only in the condition of elevated temperature and agitation, which causes the easy product separation
This invention relates to orally available compositions which deliver an amount of butyrate or a butyrate analogue effective to ameliorate &bgr;-hemoglobinopathies, such as &bgr;-thalassemia and sickle cell anemia, cystic fibrosis, cancer and other diseases which are known to be treatable with butyrate. The invention also relates to methods of treating these diseases with such low dose oral compositions.
