Investigation of the interaction of the water oxidising manganese complex of photosystem II with the aqueous solvent environment.

abstract：:We established a medium-scale real-time RT-PCR system focusing on transcription factors and applied it to their expression profiles in the adult mouse 11 brain regions (http://genome.gsc.riken.jp/qRT-PCR/). Almost 90% of the examined genes showed significant expression in at least one region. We successfully extracted...

abstract：:Human red cells suspended in lead-citrate buffers (2.6 microM Pb2+) take up much less Pb than predicted from studies of equilibrium binding of Pb to haemolysates. Pb uptake is increased by ATP depletion, or by loading at 0 degrees C. Tracer studies with 203Pb indicate that the low uptake at 37 degrees C in the presenc...
