phosphate (p) is one of the key substrates in energy metabolism and biosynthesis of nucleic acids and membranes. in order to identify molecular mechanisms involved in rice adaptation to p deficiency, we applied a proteomic approach to compare a rice parental line, nipponbare (sensitive), and its near isogenic line (nil6-4) (resistant). the experiment was conducted using a completely randomized ...

background: bone morphogenetic proteins (bmps) belong to the transforming growth factor-β (tgf-β) superfamily, and play an important role in bone metabolism. recombinant forms of bmp-2 and bmp-7 are the only bmps used clinically. in this study the mature part of human bone morphogenetic protein-7 (bmp-7) was engineered through substitution of the bmp-7 n-terminal sequence by heparin-binding sit...

introduction: suspension of isolated hepatocyes is now being used in an increasing number of biochemical investigations, including drug metabolism and toxicity studies. isolated hepatocyes, retain many of the essential properties of the intact tissue including permeability charactreristics. material and methods: in this method at first liver is subjected to a nonrecirculating perfusion with cal...
