Summary of "Hydroponic growth test of maize sprouts to evaluate As, Cd, Cr and Pb translocation from mineral fertilizer and As and Cr speciation."

The present study proposes a maize sprouts hydroponic growth model to evaluate the As, Cd, Cr and Pb translocation from multinutrient fertilizer and to do speciation of As and Cr in this fertilizer and As in parts of plant in order to predict their phytoavailability. X-ray absorption near edge structure (XANES) was employed to speciate As and Cr directly on fertilizer solid sample. Arsenate (As) and a solid solution of FeCrO were the major species identified in the samples. The sprouts were hydroponically cultivated in water, fertilizer slurry and fertilizer extract media. Concentrations of As, Cd and Pb measured on leaves of maize sprouts ranged from 0.061 to 0.31 mg kg, whereas Cr was not translocated to the aerial parts of sprouts. High performance liquid chromatographic with inductively coupled plasma mass spectrometry (HPLC-ICP-MS) analysis was used to determine As speciation in maize sprouts, as well as in the fertilizer extracts and slurries. Arsenate was the only species identified in the initial fertilizer extract and this information is in agreement with the XANES results. However, the reduction of arsenate to arsenite was observed in extracts and slurries collected after sprout growth, probably due to the action of exudates secreted by plant roots. Arsenite was the predominant species identified in sprouts, the high phosphate concentration in the medium may have contributed to reduce arsenate phytoavailability.

A projective test used to evaluate a broad range of personality variables including pathology of thought and perception. The subject's responses to inkblot prints are scored along with subjective interpretation by the test administrator.

A performance test based on forced MOTOR ACTIVITY on a rotating rod, usually by a rodent. Parameters include the riding time (seconds) or endurance. Test is used to evaluate balance and coordination of the subjects, particular in experimental animal models for neurological disorders and drug effects.

A transcriptional co-repressor that contains a MYND-type zinc finger (MYND DOMAIN) at its C-terminal and functions as a homo-oligomer. It associates with DNA-binding transcription factors, other repressor proteins, and HISTONE ACETYLTRANSFERASES to repress expression of genes involved in cell growth and differentiation such as MATRIX METALLOPROTEINASE 7 and TCF12. A CHROMOSOMAL TRANSLOCATION involving the RUNX1T1 and CORE BINDING FACTOR ALPHA 2 SUBUNIT (RUNX1) genes frequently occurs in cells of leukemia patients; the resulting fusion protein (AML1-ETO or RUNX1-RUNX1T1) plays a critical role in leukemogenesis.

A test to determine the lowest sound intensity level at which fifty percent or more of the spondaic test words (words of two syllables having equal stress) are repeated correctly.
