Two extraction procedures, i.e. a single extraction procedure using low-molecular-weight-organic-acids (LMWOAs) as extractant and a sequential extraction procedure recommended by the European Community Bureau of Reference (BCR), were performed to extract metal fractions from wet rhizosphere soil. And the extracted soil solutions were further fractionated as colloidal and truly dissolved fractions. Heavy metals in maize roots were experimentally defined as metals adsorbed on cell wall and metals taken up by cross-membrane by washing with CaCl 2 . The correlation coefficients between extractable metals from soil and taken up by maize roots and shoots were compared between two extraction methods, and a good correlation was obtained if LMWOAs were used. In contrast, the correlation coefficients were poor when the BCR method was used.

Background: The nucleolar MSP58 protein is a candidate oncogene implicated in cellular transformation.Results: MSP58 is associated with BRG1 and induces cellular senescence through the p53/p21 pathway.Conclusion: MSP58 has both tumor-suppressing and -promoting functions.Significance: This work reveals a novel role for MSP58 in cellular senescence and suggests that MSP58 may have further prognostic and therapeutic implications.

Artificial perception learning systems and artificial neural networks based on neuromorphic devices would promote the progress of neuromorphic engineering in a great extent. Here, we propose a vision enhancement and...
