57Fe Mössbauer spectroscopic results on the 2D Hofmann-like coordination polymer Fe(4-Clpy)2Ni(CN)4 (sample 1) indicate that iron(II) ions are in a high spin state both at R.T. and T = 80 K, showing that the compound exhibits no spin crossover (SCO) behavior. Mössbauer spectra at R.T. and T = 80 K show one major doublet which corresponds to the HS1 is due to high spin iron(II) sites coordinated...

Abiotic and biotic stresses have been a serious threat to crop growth productivity in the agricultural system. In this study, four strains (HS1, H30-3, KJ40, BC42), which biological activities related disease suppression or alleviation of salinity drought stresses, were tested for broad-spectrum biocontrol activity against anthracnose caused by <i>Colletotrichum orbiculare</i>, bact...

Antarctic ice cores document glacial-interglacial and millennial-scale variability in atmospheric pCO2 over the past 800 kyr. The ocean, as the largest active carbon reservoir on this timescale, is thought to have played a dominant role in these pCO2 fluctuations, but it remains unclear how and where in the ocean CO2 was stored during glaciations and released during (de)glacial millennial-scale...

The Abl-family non-receptor tyrosine kinases are essential regulators of the cytoskeleton. They transduce diverse extracellular cues into cytoskeletal rearrangements that have dramatic effects on cell motility and morphogenesis. Recent biochemical and genetic studies have revealed several mechanisms that Abl-family kinases use to mediate these effects. Abl-family kinases stimulate actin polymer...

A replication-defective recombinant retrovirus containing the human papilloma virus E6/E7 genes (LXSN-16 E6E7) was used to immortalize stromal cells from human marrow. The E6/E7 gene products interfere with the function of tumorsuppressor proteins p53 and Rb, respectively, thereby preventing cell cycle arrest without causing significant transformation. Twenty-seven immortalized clones designate...
