The Assembly of Cerium(III)-Containing Silicotungstate with Lewis Acid-Base Sites Enables the Selective -Alkenylation of Oxindole.

A cerium(III)-containing silicotungstate, [HN(CH)]NaK[KCe(SiWO)(HO)]·18.5HO (), was successfully synthesized and characterized. Structure analysis reveals that is composed of two {SiWO} units connected by one cerium(III) cation to form a typical 1:2 sandwich structure, which is further expanding into a 1D chain linked by K ions.

Treatment of lower part of glenoid fractures through a novel axillary approach: A case report.

Background: Based on the location and size of the fracture block, open reduction and internal fixation can be employed or assisted for shoulder arthroscopy in the treatment of glenoid fractures. However, the treatment of lower part of glenoid fractures through a novel axillary approach has not been reported so far.

Case Summary: A 22-year-old right-handed man was transferred to our outpatient clinic because of right shoulder injury during a traffic accident.

[Efficacy of ultrasound-guided vacuum-assisted Mammotome excision for management of benign breast diseases: analysis of 1267 cases].

Objective: To assess the clinical value of ultrasound-guided vacuum-assisted Mammotome (MMT) system for surgical resection of benign breast disease.

Methods: This retrospective study was conducted among 1267 patients who underwent minimally invasive surgery with ultrasound-guided MMT system for benign breast disease at our center between January, 2009 and January, 2014. The resection rate, incidence of complication, recurrence rate, patients' satisfaction, clinical follow-up results and risk factors were analyzed.

Tetra-kis(1H-benzimidazole-κN)(nitrato-κO)copper(II) nitrate.

In the title salt, [Cu(NO(3))(C(7)H(6)N(2))(4)]NO(3), one nitrate anion is coordinated to the Cu(II) atom, which is also coordinated by the N atoms of four N-heterocycles. The geometry at the metal atom is a square pyramid in which the O atom of the anion occupies the apical position [Cu-O = 2.468 (5) and 2.

catena-Poly[[bis-(dimethyl sulfoxide-κO)cerium(III)]tris-(μ(2)-3,5-dinitro-benzoato-κO:O')].

The polymeric title compound, [Ce(C(7)H(3)N(2)O(6))(3)(C(2)H(6)OS)(2)](n), exists as a linear chain along [111] as the three dinitro-benzoate anions each engages in bridging adjacent dimethyl sulfoxide (DMSO) coordinated Ce(III) atoms. The metal atoms are surrounded by eight O atoms in a square-anti-prismatic environment. There are two independent formula units in the asymmetric unit.

6,6'-Dihydr-oxy-3,3'-dithio-dibenzoic acid.

In the title compound, C(14)H(10)O(6)S(2), the dihedral angle between the planes of the two phenyl-ene rings is 55.9 (1)°. Both hydr-oxy groups form intra-molecular hydrogen bonds; however, one of them also engages in inter-molecular hydrogen bonding.
