Designing a Polyphosphate Polymorph of CsMg(PO) as Host Lattice for Preparing Single Mn-Oxidation Doped Phosphor in the Open Environment.

Within Mn-activated phosphors, the oxidation state of Mn dopant strongly depends on the structural features of the host lattice. This paper reported a new polymorph of CsMg(PO) (CMP) with a complicated three-dimensional (3D) framework of [Mg(PO)] that is constructed by MgO octahedra and 1D infinite [PO] chains. Then we prepared a series of red phosphors CsMg(PO):Mn (CMP:Mn) by high temperature solid state reactions in the open air.

Synthesis, crystal structure and luminescence properties of a new samarium borate phosphate, CsNaSm(BO)(PO).

A new caesium sodium samarium borate phosphate, CsNaSm(BO)(PO), has been obtained successfully by the high-temperature solution growth (HTSG) method and single-crystal X-ray diffraction analysis reveals that it crystallizes in the orthorhombic space group Cmcm. The structure contains BO, PO, NaO and SmO polyhedra which are interconnected via corner- or edge-sharing O atoms to form a three-dimensional [NaSm(BO)(PO)] network. This network delimits large cavities where large Cs cations reside to form the total structure.

KEu(PO): hydrothermal synthesis, crystal structure and photoluminescence properties.

An anhydrous orthophosphate, KEu(PO) (tripotassium pentaeuropium hexaphosphate), has been prepared by a high-temperature solid-state reaction combined with hydrothermal synthesis, and its crystal structure was determined by single-crystal X-ray diffraction analysis (SC-XRD). The results show that the compound crystallizes in the monoclinic space group C2/c and the structure features a three-dimensional framework of [Eu(PO)], with the tunnel filled by K ions. The IR spectrum, UV-Vis spectrum and luminescence properties of polycrystalline samples of KEu(PO), annealed at temperatures of 650, 700, 750, 800 and 850 °C, were investigated.

A new disordered langbeinite-type compound, KTbTaPO, and Eu-doped multicolour light-emitting properties.

For the first time, a new langbeinite-type phosphate, namely potassium terbium tantalum tris(phosphate), KTbTa(PO), has been prepared successfully using a high-temperature flux method and has been structurally characterized by single-crystal X-ray diffraction. The results show that its structure can be described as a three-dimensional open framework of [TbTa(PO)] interconnected by K ions. The Tb and Ta cations in the structure are disordered and occupy the same crystallographic sites.

Novel tantalum phosphate NaSrTa(PO): synthesis, crystal structure, DFT calculations and Dy-activated fluorescence performance.

A new tantalum phosphate, tridecasodium distrontium ditantalum nonaphosphate, NaSrTa(PO), was prepared using the high-temperature flux method. The structure can be described as a three-dimensional open framework containing isolated [Ta(PO)] units that are interlocked by Na and Sr ions. Band structure studies by the first-principles method revealed that NaSrTa(PO) is an insulator with an indirect band gap of 4.

Genetic diversity of Y-chromosome microsatellites in the Fujian Han and the Sichuan Han populations of China.

Y-chromosome short tandem repeats (STRs) are potentially useful for forensic, anthropological and evolutionary studies. In this study we chose the loci DYS 19, DYS 388, DYS 389 I, DYS 389 II, DYS 390, DYS 391, DYS 392, DYS 393, DYS 425 and DYS 426. Blood samples were taken from 46 unrelated male individuals from Fujian Han and 43 unrelated males from Sichuan Han in China.

[Establishment and preservation of immortal lymphoblastoid cell lines of the 10 ethnic groups in China].

The immortal lymphoblastoid cell lines were established by EBV transformation of B cells and addition of cyclosporin A to inhibit the activity of T cells. In the present study,549 immortal cell lines of different ethnic groups of Hazak, Manchu, Korea, Hozhe, Mongolia, Sibe, Hui, Puyi, Han in Fujian and Han in Sichuan were established. Through our research,we found it is harmful for B lymphocytes to transform if excessful leucocytes are inoculated.

[Association study of apolipoprotein e gene polymorphism and cerebral infarction in type 2 diabetic patients].

In order to explore the association of apolipoprotein E (ApoE) gene polymorphism with cerebral infarction in type 2 diabetic patients of Han nationality in Northeast China , the genotypes of ApoE gene were analyzed by polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) in the 208 cases, including 69 cases in control (CON) group and 67 in type 2 diabetes mellitus (T2DM) group as well as 72 in type 2 diabetes mellitus with cerebral infarction (T2DMCI) group. Plasma lipid content in T2DMCI was also detected for 70 cases. The distribution of genotypes in ApoE gene,epsilon(2)epsilon(3),epsilon(3)epsilon(3) as well as epsilon(3)epsilon(4) was no significant difference in three groups (epsilon(2)epsilon(3) : 13.

Objective: To analyze the genetic polymorphism of 15 single nucleotide polymorphism (SNP) loci on the nonrecombining portion of the Y chromosome in 6 populations in China.

Methods: Allelic specific polymerase chain reaction and 2% agarose gel electrophoresis and 6% PAGE were used to analyze the genetic polymorphism of 343 unrelated males, representing 6 populations in China, including Fujian Hans, Sichuan Hans, Mongolian, Hezhen, Sibo and Hui from the South, Northeast and Northwest.

Results: Thirty haplogroups were observed, and 3 of them (H15, H16, H18) were seen in all of the six populations.

[Y chromosome variations and hyplogroups from 15 biallelic markers in six Chinese populations].

By using 15 biallelic markers, 342 male individuals from six populations in China were genotyped with ASPCR (allele specific PCR). The 15 biallelic markers included M1 (YAP), M15 (9 bp insertion), M89 (C-->T), M9 (C-->G), M119 (A-->C), M50 (T-->C), M110 (T-->C), M103 (C-->T), M95 (C-->T), M88 (A-->G), M111 (2-bp deletion), M45 (G-->A), M122 (T-->C), M7 (C-->G) and M134 (1 bp deletion). The distribution of variation frequencies of 15 biallelic markers in six populations showed that with the extremely high frequencies of M9G (96.
