During our research into novel nonlinear optical materials using 1,10-phenanthroline as an appending ligand on lanthanide iodates, crystals of an infinite layered Dy(III) iodate compound, Dy(IO(3))(3)(H(2)O)·H(2)O, were obtained under hydro-thermal conditions. The Dy(III) cation has a dicapped trigonal prismatic coordination environment consisting of one water O atom and seven other O atoms fro...

A patient with seropositive, nodular rheumatoid arthritis (RA) developed contact allergy to gold jewellery following a severe skin rash which occurred after 13 weeks of treatment with sodium aurothiomalate. Patch testing confirmed that the contact allergy was due to gold. This is the first proved case of contact allergy to gold or any other compound initiated by systemic administration of the a...

BACKGROUND The efficacy of inhaled salmeterol plus fluticasone propionate (SFC) in patients with severe or very severe COPD is well documented. However, there are only limited data about the influence of GOLD severity staging on the effectiveness of SFC, particularly in patients with milder disease. METHODS TORCH was a 3-year, double-blind, placebo-controlled trial of 6112 patients with moder...

Gold nanoparticles have particular properties distinct from those of bulk gold crystals, and such nanoparticles are used in various applications in optics, catalysis, and drug delivery. Many reports on microbial synthesis of gold nanoparticles have appeared. However, the molecular details (reduction and dispersion) of such synthesis remain unclear. In the present study, we studied gold nanopart...

The novel 5,10-dihydrophencomycin methyl ester (4) and the known microbial metabolites (2-hydroxyphenyl)-acetamide (1), menaquinone MK9 (II, III, VIII, IX-H8) (2), and phencomycin (3a) were isolated from an unidentified marine Streptomyces sp. and the structures were elucidated by NMR methods. Compound 4 shows weak antibiotic activity against Escherichia coli and Bacillus subtilis.

Anchoring a BODIPY onto Ga(III)corrole via a meso-β linkage facilitated PeT in polar solvents, which quenched the fluorescence, and is further confirmed by electrochemical studies. The triad exhibits unprecedented crystal emission, which is not known for a corrole derivative, due to unique packing. Compound 4 hosts the first example of a novel B-F∙∙∙F interaction as well.
