Ratiometric fluorescent detection of dipicolinic acid as an anthrax biomarker based on a high-nuclearity Yb nanoring.

An 18-metal lanthanide nanoring [Yb(L)(HL)(OAc)(MeOH)(EtOH)(HO)] (1), which shows a ratiometric fluorescent response to DPA, was constructed through the strategy of using two types of polydentate organic ligands. The addition of DPA increases the visible ligand-centered emission, but decreases the NIR lanthanide luminescence of 1. The limit of luminescent detection of 1 for DPA is 1.

Luminescent Polynuclear Zn- and Cd-Ln Square-Like Nanoclusters With a Flexible Long-Chain Schiff Base Ligand.

Two series of Zn-Ln and Cd-Ln nanoclusters [LnZnL(OAc)(OH)] [Ln = Nd (), Yb (), and Sm ()] and [LnCdL(OAc)(OH)(OCH)] [Ln = Nd (), Yb (), and Sm ()] were prepared using a long-chain Schiff base ligand with a flexible (CH)O(CH)O(CH) chain. All these clusters show square-like structures. The Schiff base ligands show "linear" configurations in the structures of -, and the metric dimensions of Zn-Ln and Cd-Ln clusters measure ~8 × 14 × 21 and 8 × 12 × 12 Å, respectively.

[Effect of remote controlled injection manipulator system assisted percutaneous kyphoplasty for treatment of rupture of posterior vertebral osteoporotic vertebral fracture].

Objective: To evaluate the effect of remote controlled injection manipulator system (RCIM) assisted percutaneous kyphoplasty (PKP) for the treatment of rupture of posterior vertebral osteoporotic vertebral fracture by comparing with intermittent hand bolus injection of bone cement during operation.

Methods: Between September 2010 and January 2016, a retrospective analysis was made on the clinical data of 48 senile patients with single segment rupture of the posterior vertebral osteoporotic thoracolumbar fracture undergoing PKP who accorded with the inclusion criteria. Of 48 patients, 22 received intermittent hand bolus injection of bone cement in the control group, and 26 received RCIM assisted bone cement perfusion in the trial group.

Construction of luminescent high-nuclearity Zn-Ln rectangular nanoclusters with flexible long-chain Schiff base ligands.

Three Zn-Ln clusters [LnZn(L)(OAc)(O)(NO)(OH)] (Ln = Sm (1) and Nd (2)) and [NdZn(L)(OAc)(NO)(OH)] (3) were prepared using two long-chain Schiff base ligands. The Zn-Ln clusters exhibit interesting nano-square-like structures. Their visible and NIR luminescence properties were investigated.
