Effect of oxidation treatment on the adsorption and the stability of mercury on activated carbon.

Oxidation treatment on the adsorption and the stability of Hg on activated carbon (AC) was inrestigated. Both MnO2-AC and FeCl3-AC were produced during oxidation treatment. The measurement of modified AC's mercury adsorption capacity was conducted in a simulated coal-fired flue gas by adsorbing test apparatus.

Effects of transforming growth factor-beta1 and signal protein Smad3 on rat cardiomyocyte hypertrophy.

Background: SMAD proteins have recently been identified as the first family of putative transforming growth factor-beta1 (TGF-beta1) signal transducers. This study was to investigate the effects of TGF-beta1 and signal protein Smad3 on rat cardiac hypertrophy.

Methods: The incorporation of [(3)H]-leucine was measured to determine the hypertrophy of cardiomyocyte incubated with different doses of TGF-beta1 in cultured neonatal cardiomyocytes.
