About half of the thiamin in the U.S. diet comes from foods that naturally contain thiamin; the remainder comes from foods to which thiamin has been added . Heating foods containing thiamin can reduce their thiamin content.
Plasma technology is based on a simple physical principle. Matter changes its state when energy is supplied to it: solids becomes liquid, and liquids becomes gaseous. If even more energy is supplied to a gas, it is ionized and goes into the energy-rich plasma state, the fourth state of matter.
BACKGROUND: A photochemical treatment (PCT) process has been developed to inactivate pathogens and white blood cells (WBCs) in therapeutic plasma. Process validation studies were performed in three European blood centers under routine operating conditions. STUDY DESIGN AND METHODS: Each center prepared 30 apheresis and 30 to 36 whole bloodâderived plasma units for PCT. Each whole bloodâderived plasma unit contained a mixture of two to three matched donations.
