Three new findings are reviewed that help to understand the mechanisms of action of antirheumatic Au(I) drugs, such as disodium aurothiomalate (Na(2)Au(I)TM): (i) We found that Na(2)Au(I)TM selectively inhibits T cell receptor (TCR)-mediated antigen recognition by murine CD(4+) T cell hybridomas specific for antigenic peptides containing at least two cysteine residues. Presumably, Au(I) acts as...

A theoretical study on the nature of Au-XO(0,-1,+1) (X=C, N, O) interaction is carried out in order to provide a better understanding on the adsorption process of XO molecules on Au surfaces or Au-supported surfaces. The effect of the total charge as well as the presence of an external electric field on the formation processes of the Au-XO complex are analyzed and discussed using DFT (B3LYP) an...

OBJECTIVE To evaluate the effect of adalimumab on the frequency of anterior uveitis (AU) flares in patients with active ankylosing spondylitis (AS). METHODS We determined the history of ophthalmologist-diagnosed AU in 1250 patients with active AS who were enrolled in a multinational, open-label, uncontrolled clinical study of treatment with adalimumab, 40 mg every other week for up to 20 week...

In the title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], the Au(I) atom has a near-linear geometry, defined by an S,P-donor set [S-Au-P = 175.09 (5)°]. The proximity of the meth-oxy O atom to Au may be responsible for the deviation from linearity [Au⋯O = 2.959 (4) Å].

A series of coordination polymers containing Cu(II) and [Au(CN)(2)](-) units has been prepared. Most of their structures incorporate attractive gold-gold interactions, thus illustrating that such "aurophilic" interactions can be powerful tools for increasing structural dimensionality in supramolecular systems. [Cu(tren)Au(CN)(2)][Au(CN)(2)] (1, tren = tris(2-ethylamino)amine) forms a cation/ani...

The use of nanowires (NWs) for labeling, sensing, and sorting is the basis of detecting biomolecules attached on NWs by optical and magnetic properties. In spite of many advantages, the use of biomolecules-attached NWs sensing by photoelectrochemical (PEC) study is almost non-existent. In this article, the PEC study of dye-attached single-stranded DNA on Au NWs and Au-Ni-Au multilayer NWs prepa...

A new series of solids with ligand-unsupported Au(I) chains with short Au...Au contacts were synthesized; as Ag compounds with the same structure are known, the new phases now allow unbiased comparison of Ag...Ag and Au...Au metallophilic bonds not supported by bridging ligands, which shows the latter to be consistently shorter by 0.03-0.04 A.

Clusters of noble metals, particularly gold, with precise nuclearity (number of atoms) and overall molecular composition continue to be a topic of intense experimental and theoretical research endeavors. These efforts aim at understanding the basic factors, such as electronic structure, atomic packing, and adsorbed layers that underlie the appearance of certain structural motifs and control the...

Measurements of identified particle production with the PHENIX experiment at RHIC have reached a mature state, where a multitude of nuclear systems at different colliding energies have been studied. The discovery configurations of √ sNN = 130 and 200 GeV Au+Au collisions have now been supplemented by additional Au+Au and Cu+Cu configurations at various energies, along with baseline p+p and d+Au...
