Abstract

Studies on the interaction of DNA with vitamin B(6) were carried out with a DNA-modified electrode by electrochemistry and Ultraviolet-visible spectroscopy. The results showed that there exists the supra-molecule interaction between base groups on DNA and vitamin B(6) by forming hydrogen binding, the binding equilibrium constant of the interaction is equal to 115.3 M(-1), the binding ratio of nucleotide to vitamin B(6) is 5:1. Based on the electrochemical and Ultraviolet-visible spectrum studies the interaction mode of DNA with vitamin B(6) was explored.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
