Bimetallic Au-based nanoparticles (Au-M where M = Pt, Pd, Cu, Ni), synthesized by simultaneous reduction of the Au salt with noble/non-noble metal salts, exhibit a high activity for the aminoalkene (2,2-diphenylpent-4-en-1-amine) hydroamination affording the 5-membered Markovnikov product. Even though the particle size and morphology of Au-M nanoparticles are comparable to the corresponding mon...

Abstract. Recent results on high transverse momentum (pT ) hadron production in p+p, d+Au and Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) are reviewed. Comparison of the nuclear modification factors, RdAu(pT ) and RAA(pT ), demonstrates that the large suppression in central Au+Au collisions is due to strong final-state effects. Theoretical models which incorporate jet quenchi...

BACKGROUND CXCR4 chemokine receptor is constitutively expressed on normal and malignant B lymphocytes derived from patients with B-cell lymphoproliferative disorders and has a significant role in cell migration to lymph nodes and bone marrow. Non-Hodgkin's lymphomas (NHL) constitute a heterogeneous group of lymphoproliferative diseases, which can localize not only to lymph nodes, but also can m...

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.
