Bis(tetra-butyl-ammonium) tetra-chlorido-manganate(II) di-chloro-methane disolvate.

The title compound, (CHN)[MnCl]·2CHCl, is an ionic organic-inorganic hybride compound consisting of a tetra-butyl-ammonium cation and a tetra-chlorido-manganate(II) anion in a 2:1 stoichiometric ratio. The cation contains a central nitro-gen atom bonded to four -butyl groups in a tetra-hedral arrangement, while the anion contains a central Mn atom tetra-hedrally coordinated by four chlorido ligands. It co-crystallized with two equivalents of di-chloro-methane solvent, CHCl, to give the following empirical formula: [(CH)N][MnCl]·(CHCl).

Analytical Methods for Pesticide Residues in the Water Environment.

A review of literature published in 2014 focusing on analytical methods for pesticides in the water environment is presented here. The review includes publications on extraction methods and on analytical methods such as biochemical assays and immunoassays, electrochemical methods, chromatographic or mass spectrometric techniques, spectrophotometric techniques, fluorescence, and chemiluminescence techniques.

Survivorship of the native hip joint after percutaneous repair of acetabular fractures in the elderly.

Our purpose was to examine survivorship of the native hip joint in patients ages 60 and over who underwent percutaneous reduction and fixation of acetabular fractures. A retrospective review at a University Level I Trauma Center was performed. Our institutional trauma database was reviewed.

Cephalomedullary nails in the treatment of high-energy proximal femur fractures in young patients: a prospective, randomized comparison of trochanteric versus piriformis fossa entry portal.

Objective: The purpose of this study is to compare a cephalomedullary nail that uses a piriformis fossa starting point to one that uses a trochanteric starting point, in the treatment of high-energy proximal femur fractures in young patients. Our hypothesis was that a nail that uses a trochanteric starting point would result in less blood loss than a nail that uses a piriformis fossa starting point.

Design: Prospective, randomized.
