Dr. Jinsong Zhang is an associated professor in University of Science and Technology of China. He and his colleagues found and elucidated nano red elemental selenium (Nano-Se). Their finding challenges longheld dogma that elemental selenium is biological inert and shows this kind of selenium in nano size is highly active with lower toxicity. In this talk, Dr. Zhang explain why selenium is extraordinary, essential, and enigmatic,also he describe his experience of Nano-Se research and novel properties of Nano-Se.
Up to 70% adult is in the subhealth state. It is essential to guarantee the antioxidantive balance and prevent selenium deficiency. NANO-Se is the high-efficient and high safe red nano selenium synthesized by nanotechnology. That is to say, a low dosage supplementation is equivalent to higher dosage in other forms, meanwhile avoids unnecessary side effect.
Selenium is a promising agent for chemoprevention and chemotherapy of cancer. However, present research data indicate the supranutritional dose and even higher level are necessary for better efficacy. These doses approaches toxic dose. The dilemma in selenium argues the exploration of novel selenium form with lower toxicity and higher biological functions is urgent. The long-held opinion is elemental selenium is biological inert. We show that elemental in nano particles has high bioavailability and substantial low toxicity, indicating its promising application in chemoprevention and chemotherapy.
This review analyzes the research data of selenium in liver diseases conducted by China scientists in recent years. It is found from these researches that suboptimal selenium in serum is a common phenomenon of liver diseases, the severer, the more deficient; supplementation of selenium in nutritional level is beneficial for diseases control and better recovery of drug treatments; selenium may inhibit hepatitis virus by adjusting immunity,increasing antioxidant defense, and suppressing mutation; selenium at nutritional level could prevent liver fibrosis in rats models as well as liver cancer in either animal models or human beings
