Device implantation complicated by a retrosternal goiter.

Central venous obstruction in the cardiac implantable electronic devices (CIED) population is commonly due to thrombosis and fibrosis secondary to the passage of pre-existing leads. However, vein occlusion before CIED implantation is uncommon, and one cause is retrosternal goiters. We report a case where the failure of the initial implantation of a primary CIED led to an unusual implantation route without goiter excision.

Synthesis, spectral characterization and crystals structure of some arsane derivatives of gold (I) complexes: a comparative density functional theory study.

A series of complexes of the type LAuCl where L = tris(p-tolylarsane), tris(m-tolylarsane), bis(diphenylarsano)ethane, and tris(naphthyl)arsane have been synthesized. All of the new complexes, 1-4, have been fully characterized by means of ¹H NMR and ¹³C NMR spectroscopy and single crystal X-ray crystallography. The structures of complexes 1-4 have been determined from X-ray diffraction data.

μ-1,6-Bis(diphenyl-arsan-yl)hexa-ne]bis-[chloridogold(I).

In the title compound, [Au(2)Cl(2)(C(30)H(32)As(2))], each Au atom is coordinated by As and Cl atoms in an approximately linear geometry. In the crystal, mol-ecules are linked into two-dimensional networks parallel to the ac plane via inter-molecular C-H⋯Cl inter-actions. One of the phenyl rings is disordered over two positions, with site occupancies of 0.

(Benzyl-diphenyl-phosphane)chlorido-gold(I).

In the title compound, [AuCl(C(19)H(17)P)], the Au(I) atom exists within a P and Cl donor set that constitutes an almost linear geometry. The three phenyl rings make dihedral angles of 38.33 (14), 81.

Chlorido[tris-(3-fluoro-phen-yl)phosphine]gold(I).

In the title gold complex, [AuCl(C(18)H(12)F(3)P)], the P-Au-Cl unit is nearly linear, with an angle of 178.13 (5)°. The three phosphine-substituted benzene rings make dihedral angles of 77.

A novel high performance liquid chromatographic method for simultaneous determination of ceftriaxone and sulbactam in sulbactomax.

An isocratic liquid chromatographic method with UV detection at 220 nm is described for simultaneous determination of ceftriaxone sodium and sulbactam sodium in Sulbactomax. Chromatographic separation of two drugs was achieved on a Hypersil ODS C-18 column using a mobile phase consisting of a binary mixture of acetonitrile and tetrabutyl ammonium hydroxide adjusted to pH7.0 with orthophosphoric acid in ratio 70:30.

Photocatalytic degradation of disperse blue 1 using UV/TiO2/H2O2 process.

The photocatalytic degradation of a dye derivative, C.I. disperse blue 1 (1), has been investigated under UV light irradiation in the presence of TiO2 and H2O2 under a variety of conditions.

Semiconductor-mediated photocatalysed degradation of two selected azo dye derivatives, amaranth and bismarck brown in aqueous suspension.

Semiconductor-mediated photocatalysed degradation of two selected azo dye derivatives such as amaranth (1) and bismarck brown (2) has been investigated in aqueous suspension by monitoring the change in substrate concentration employing UV spectroscopic analysis technique as a function of irradiation time. The degradation was studied under different conditions such as types of TiO(2), pH, substrate concentration, catalyst concentration, and in the presence of electron acceptors such as hydrogen peroxide (H(2)O(2)), potassium bromate (KBrO(3)) and ammonium persulphate (NH(4))(2)S(2)O(8) besides air. The degradation rates were found to be strongly influenced by all the above parameters.
