The Eu ion, with the 4f5d electronic configuration, is one of the most important activated ions due to its symmetry-allowed 4f → 5d electron transition. Herein, we successfully prepared a new type of blue phosphor, NaCsMg(PO):Eu (NCMP:Eu), in which Eu occupies the Na sites of the host lattice. Under 395 nm light excitation, a broad emission band from 410 to 550 nm can be seen, peaking at 458 nm, due to the 5d → 4f transition of Eu.

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.

A new stibium phosphate, lithium barium bis(antimony oxide) tris(phosphate), LiBa(SbO)(PO), was prepared by the molten salt method with LiF as the flux. The crystal structure consists of an original three-dimensional anionic framework of [(SbO)(PO)] built from PO tetrahedra sharing their corners with SbO octahedra. This framework delimits one-dimensional tunnels where the lithium(I) and barium(II) ions are located.

MiRNA-335 is a classic tumor suppressor, yet its expression pattern and biological role in MM is unclear. The aim of the present study was to determine the expression pattern, biological role, and mechanism of miR-335 in MM.

The changes in the molecular structure of HEC treated with enzymatic approach in comparison to the native HEC were studied through nuclear magnetic resonance (NMR), fourier transform infrared spectra (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques and kinetics of degradation was studied by viscometry. The cleavage of HEC chains could be observed from FTIR and kinetics results.

Objective: We aimed to quantitatively evaluate the effect of green tea on glucose control and insulin sensitivity.
Design: We performed a strategic literature search of PubMed, EMBASE, and the Cochrane Library (updated to January 2013) for randomized controlled trials that evaluated the effects of green tea and green tea extract on glucose control and insulin sensitivity.

Objective: To study the differential microRNAs expression between patients with essential hypertension and healthy controls.
Methods: Whole blood from 15 hypertensive patients and 5 controls healthies were separated into plasma at 3000 rpm for 10 minutes. MicroRNAs were harvested using kit, and stored at -80°C.
