The spin Hamiltonian parameters (SHPs) of Cu2+‐doped halo‐glasses PbX2–PbO–B2O3 (X = F and Br) are investigated by means of the perturbation method where the impact of the halides and the local structure of the dopants, that is, the [CuO6]10− clusters suffering the tetragonal elongation distortions, is involved. By comparing with the obtained results of the 3d1 system (VO2+), Cu2+ and V4+ are complementary state, which show opposite distortions. Furthermore, the d‐d transition bands and the sign of anisotropy g factors also show whole opposite concentration variation trends with similar fluctuations due to the increase of non‐bridging oxygen (NBO). The values of the optical basicity Λth referring to the Pauling electronegativity, whose influence on E1 and g factors are also discussed. The above correlations would be beneficial to analyze and predict the properties of analogous borate glasses and ceramics when doped with different transition metal ions. [ABSTRACT FROM AUTHOR]

The mixed‐metal pillar‐layered metal–organic frameworks of Zn(bdc)(DABCO)0.5, Zn0.5Cu0.5(bdc)(DABCO)0.5 and Cu(bdc)(DABCO)0.5 (bdc = 1,4‐benzenedicarboxylate, DABCO = 1,4‐diazabicyclo[2.2.2]octane) are investigated for their local structures and gas adsorption properties. According to the obtained electron paramagnetic resonance (EPR) spectra, the distorted structures around Cu2+ are proposed to be tetragonally and orthorhombically elongated [CuO4N] with the well fitted high‐order perturbation formulae of the EPR parameters. Due to the doped Cu2+, the adsorption isotherms of industrially relevant gases (CO2, CO, CH4 and N2) and lower alkanes (CH4, C2H6, C3H8, C4H10 and C5H12) are different, especially at different temperatures. By combining the structural properties and adsorption isotherms, a comprehensive study suggests that the ZnDABCO series can be a controllable tool in gas storage and separation.

Objective: To investigate the relationship between partial reversed cell polarity (PRCP) and lymphatic tumor spread in invasive ductal carcinoma (IDC), not othervise specified (NOS)., Methods: Immunohistochemistry (EnVision method) was used to examine the expression of epithelial membrane antigen (EMA) and the reversed cell polarity in 199 cases of IDC., Results: Of the 199 cases, including five cases with micropapillary differentiation,30 cases with PRCP and 164 cases of IDC-NOS (without micropapillary differentiation and/or PRCP), lymphovascular invasion was seen in four (4/5), 13(43.3%) and 30 cases (18.3%) respectively; nodal metastasis was seen in four (4/5), 19 (63.3%) and 56 cases (34.1%) respectively. The rates of lymphovascular invasion and nodal metastasis were significantly higher in IDC with PRCP or IMPC than IDC-NOS (P = 0.00); there was however no significant difference between IDC with PRCP and IMPC for lymphovascular invasion and nodal metastasis (P = 0.18, P = 0.64)., Conclusions: IDC with PRCP, similar to IMPC, is more likely to show lymphovascular invasion and nodal metastasis. Complete or partial reversal of cell polarity may play a significant role in lymphatic tumor spread.

This study was conducted to clone the prolactin gene (PRL) in Eastern Zhejiang White Geese and to investigate the PRL gene expression characteristics during egg-laying, out-of-lay and incubating periods by real time PCR. Comparisons were made respectively of concentration of prolactin mRNA in the hypothalamus, pituitary gland and ovary of the adult female geese at different reproductive periods. The result indicated that there were significant differences (P<0.05) in PRL mRNA expression between different reproductive periods of the geese. The lowest level of PRL expression was found in out-of-lay geese, higher in the egg-laying geese, and the highest in incubating geese. Furthermore, the analysis of PRL expression in different tissues indicated that the highest levels of PRL was expressed in the pituitary gland, followed in hypothalamus, and the least in ovary of the geese. There were significant difference (P<0.01) expression of PRL between the pituitary gland/hypothalamus and ovary of the geese, whereas no any difference was observed between the pituitary gland and hypothalamus (P>0.05). In summary, the PRL mRNA expression had variance in different reproductive periods of the geese.
