A series of NaLuF4-based hexagonal phase upconversion nanocrystals (UCNs) were synthesized by a facile solvothermal method and the properties of the UCNs were investigated. The results show that the as-prepared nanocrystals exhibit pure hexagonal lattice structures, uniform morphologies, high monodispersities and excellent upconversion luminescence. The upconversion luminescence (UCL) intensiti...
Er(3+)/Yb(3+)/Pr(3+): SrGdGa3O7 crystal was firstly grown by Czochralski method. Detailed spectroscopic analyses of Er(3+)/Yb(3+)/Pr(3+): SrGdGa3O7 were carried out. Besides better absorption characteristic, the spectra of Er(3+)/Yb(3+)/Pr(3+): SrGdGa3O7 show weaker up-conversion and near-infrared emissions as well as superior mid-infrared emission in comparison to Er(3+): SrGdGa3O7 and Er(3+)/...
Proof of Theorem 4. For wa ∈ [c + ck, rck w−c ], we have the boundary equilibrium. From its definition, yb(ξ) is decreasing in wa (that is, dyb(ξ) dwa < 0) and yb(ξ) = μ + ξ + G−1( r−c−ck r ) when wa = c + ck. The total supply chain profit at the boundary equilibrium is Πtot(yb(ξ), yb(ξ), ξ) = rEmin(μ + ξ + , yb(ξ)) − (c + ck)y(ξ) from Equations (16) and (17). This function is concave and incre...
The Y-box-binding protein 1 (YB-1), a member of the cold-shock domain RNA-and DNA-binding protein family, has pleiotropic functions such as regulation of the cell cycle. The aim of this study was to evaluate if YB-1 is a proliferative marker in breast cancer and elucidate potential downstream targets involved in YB-1-mediated cell cycle regulation using RNA interference technology. YB-1 protein...
BACKGROUND Y-Box-binding protein-1 (YB-1) acts as a transcription factor for multiple genes and is linked to DNA replication and repair, cell proliferation and resistance to cytostatic drugs. PATIENTS AND METHODS The prognostic value of YB-1 expression in primarily untreated malignant non-Hodgkin's lymphomas (NHLs) was examined using immunohistochemistry. RESULTS Expression of YB-1 was dete...
We realize simultaneous quantum degeneracy in mixtures consisting of the alkali and alkaline-earth-like atoms Li and Yb. This is accomplished within an optical trap by sympathetic cooling of the fermionic isotope ⁶Li with evaporatively cooled bosonic ¹⁷⁴Yb and, separately, fermionic ¹⁷³Yb. Using cross-thermalization studies, we also measure the elastic s-wave scattering lengths of both Li-Yb co...
The overexpression of the epidermal growth factor receptor (EGFR) and HER-2 underpin the growth of aggressive breast cancer; still, it is unclear what governs the regulation of these receptors. Our laboratories recently determined that the Y-box binding protein-1 (YB-1), an oncogenic transcription/ translation factor, induced breast tumor cell growth in monolayer and in soft agar. Importantly, ...
BACKGROUND Y-box binding factor 1 (YB-1) has been associated with prognosis in many tumor types. Reduced YB-1 expression inhibits tumor cell growth, but the mechanism is unclear. METHODS YB-1 mRNA levels were compared with tumor grade and histology using microarray data from 771 breast cancer patients and with disease-free survival and distant metastasis-free survival using data from 375 of t...
CaLa2-x(MoO4)4:Ho(3+)/Yb(3+) phosphors with the doping concentrations of Ho(3+) and Yb(3+) (x = Ho(3+) + Yb(3+), Ho(3+) = 0.05; Yb(3+) = 0.35, 0.40, 0.45 and 0.50) have been successfully synthesized by the microwave sol-gel method. The modulated and averaged crystal structures of CaLa2-x(MoO4)4:Ho(3+)/Yb(3+) molybdates have been found by the Rietveld method, and the upconversion photoluminescen...
Proteasome-mediated cleavage of the Y-box-binding protein 1 is linked to DNA-damage stress response.
YB-1 is a DNA/RNA-binding nucleocytoplasmic shuttling protein whose regulatory effect on many DNA- and RNA-dependent events is determined by its localization in the cell. Distribution of YB-1 between the nucleus and the cytoplasm is known to be dependent on nuclear targeting and cytoplasmic retention signals located within the C-terminal portion of YB-1. Here, we report that YB-1 undergoes a sp...
