Apr 02, 2019 Plasma activated deionized water from a hot arc 150 W PAW synthesizer has been analyzed for nitrite, nitrate and peroxide densities. Observed nitrite and nitrate levels are impressive, reaching several millimoles per liter at few hundred kiloJoules per liter energy input. Nitrate levels appear positively influenced by the applied energy density, together with a less …

Propaedeutic study for the delivery of nucleic acid-based ...

Introduction. Nucleic acid-based drugs (NABD) represent a novel group of molecules with the potential to treat several different human diseases (Grassi et al 2004; Heidenreich 2004).Because all are constituted by either RNA, such as small interfering RNAs (Hannon and Rossi 2004) or DNA, such as DNA enzymes (Breaker 1997), NABD are rapidly destroyed in physiological fluids.
