Wehave developed a facile low-temperature synthetic method for the preparation of NaMnF3 nanocubes with Er 3+ and Yb ions homogeneously incorporated in the host lattice. The effects of the reaction temperature, and the volume ratio between ethanol and DI water on themorphology of NaMnF3 nanocubes are systematically investigated. The NaMnF3 nanocubes can be produced in the low temperature range ...

Mass selection by independent culling levels (YB subline) for below-average birth weight (BWT) and high yearling weight (YWT) was compared with single-trait mass selection (YW subline) for high YWT in the inbred population of Line 1 Hereford cattle at Miles City, Montana. There were 4.2 generations of selection in YB and YW. Heritability estimates for the base population derived from multiple-t...

The translocation liposarcoma protein TLS has recently been shown to function as an adapter molecule coupling gene transcription to RNA splicing. Here we demonstrate that YB-1, a protein known to play important roles in transcription and translation, interacts with the COOH-terminal domains of TLS and the structurally related Ewing's sarcoma protein EWS. Through this interaction, YB-1 is recrui...

We have isolated a Yb-subunit cDNA clone from a GSH S-transferase (GST) cDNA library made from rat liver polysomal poly(A) RNAs. Sequence analysis of one of these cDNA, pGTR200, revealed an open reading frame of 218 amino acids of Mr = 25,915. The deduced sequence is in agreement with the 19 NH2-terminal residues for GST-A. The sequence of pGTR200 differs from another Yb cDNA, pGTA/C44 by four ...

Amplification of the Neu (ErbB-2 or HER-2) receptor tyrosine kinase occurs in 20 to 30% of human mammary carcinomas, correlating with a poor clinical prognosis. We have previously demonstrated that four (Y1144 Y1201, Y1227 and Y1253) of the five known Neu autophosphorylation sites can independently mediate transforming signals. The transforming potential of two of these mutants correlates with ...

The [Yb(5,7ClQ)(2)(H5,7ClQ)(2)Cl] (1) complex, that exhibits dual-luminescence in the visible (ligand-centered) and in the NIR (Yb-centered), has been incorporated into a silica sol-gel glass obtaining 1-doped glassy material which is optically transparent and homogeneous and with good mechanical properties. The doped sol-gel glass can be considered a "solid state solution" and photophysical st...

The asymmetric unit of the title compound, [Yb(4)Zn(4)(C(4)H(5)O(2))(20)(C(10)H(8)N(2))(2)(H(2)O)(4)], contains half of a centrosymmetric octa-nuclear mol-ecule in which each Zn(II) ion is four-coordinated by three O atoms from three 2-methyl-prop-2-enoate (L) ligands and one N atom from a 4,4'-bipyridine (bipy) ligand in a distorted pyramidal geometry. The two independent Yb(III) ions, each co...

Reaction of [M(NacNac)I(THF)]n (M = Mg, Ca or Yb; n = 1 or 2) with KFp gave Mg(NacNac)Fp(THF) (, Mg-Fe = 2.6326(4) Å) or [M(NacNac)(μ-Fp)(THF)]2 (M = Ca or Yb (10), no M-Fe bonds); reaction of with [YbFp2(THF)3]2 gave [{Yb(NacNac)(THF)}2(μ-YbFp4)] (Yb-Fe = 2.9758(5)-3.1702(5) Å) containing the first example of a lanthanide bound solely to four transition metals; reaction of with TolNCNTol gave ...

We have successfully loaded a magneto-optic trap for Yb atoms from a thermal source without the use of a Zeeman slower. The source is placed close to the trapping region so that it provides a large flux of atoms that can be cooled and captured. The atoms are cooled on the 1S0 ↔ 1P1 transition at 398.8 nm. We have loaded all seven stable isotopes of Yb into the trap. For the most abundant isotop...

YB-1, a multifunctional DNA- and RNA-binding nucleocytoplasmic protein, is involved in the majority of DNA- and mRNA-dependent events in the cell. It consists of three structurally different domains: its central cold shock domain has the structure of a β-barrel, while the flanking domains are predicted to be intrinsically disordered. Recently, we showed that YB-1 is capable of forming elongated...
