A simple, label-free method for the detection of thrombin has been developed based on the conformational transition of aptamer in the presence of the target by using a molecular light switch, Ru polypyridine complex, and quantum dots as novel fluorescence probes in aqueous solution.

A new lipophilic Ru salen complex with cholesterol groups can be efficiently incorporated into liposome bilayers, allowing the photoinduced release of nitric oxide (NO) and the membrane transport of NO to coexisting liposomes.

The crystal structure of the dinuclear arene ruthenium title complex, [Ru2(C6H5OS)(C7H7S)2(C10H14)2]BF4, shows the two Ru(II) atoms to be bridged by two benzyl-thio-pheno-late units and one 4-hy-droxy-thio-pheno-late unit, with the remaining three coordination sites of each Ru(II) atom being occupied by p-cymene ligands, completing the typical piano-stool coordination geometry. The BF4 (-) coun...

Insight into how H2 O is oxidized to O2 is envisioned to facilitate the rational design of artificial water oxidation catalysts, which is a vital component in solar-to-fuel conversion schemes. Herein, we report on the mechanistic features associated with a dinuclear Ru-based water oxidation catalyst. The catalytic action of the designed Ru complex was studied by the combined use of high-resolut...

The first series of cyclometalated ruthenium complexes with a CCC-pincer bis-carbene ligand have been obtained as bench-stable compounds. Single-crystal X-ray analysis of one of these complexes with 4'-di-p-anisylamino-2,2':6',2''-terpyridine is presented. The Ru(II/III) redox potentials and MLCT absorptions of these complexes can be varied by attaching an electron-donating or -withdrawing grou...

Aimed at creating a true photoswitchable energy transfer system, four dinuclear complexes containing ruthenium(II) and osmium(II) metal centers bridged by spiropyran-type linkers were designed and investigated. The bridge in its closed spiropyran form was shown to be a good insulator for energy transfer between the Ru-bpy donor and the Os-bpy acceptor (bpy = 2,2'-bipyridine). On the basis of pr...

This Article contains an error in Figure 2c, where the y-axis 'μ g [Ru]/mg [cell protein]' is incorrectly labelled as 'ng [Ru]/mg [cell protein]'. The correct Figure 2c appears below as Figure 1.

This speech addressed itself to the variety of achievement motivations that can be critically different for men and women. The author, impressed by the different wars people cognitively define and experience a successful accomplishment, developed a taxonomy of psychological 'cues which people might use in defining their success. Six varieties of achievement motivation were reviewed: (1) autonom...

Assume that a1j 6= 0 for j = 2 . . . n. Then the (1, 1) element of A∗A is equal to a11+a12+. . .+a1n. The (1, 1) element of AA∗ is equal to a11. Since A is normal, a 2 11 + a 2 12 + . . . + a 2 1n = a 2 11 and, therefore, a1j = 0 for j = 2 . . . n. Now assume that a2j 6= 0 for j = 3 . . . n. Using the above proven fact that a12 = 0 we can compare the (2,2) entries of A∗A and AA∗ to show that al...

OBJECTIVES To evaluate the micro-tensile bonding strength (muTBS) of three luting resins to human regional dentin. METHODS Dentin disks from non-carious third molars were prepared from different regions (s, superficial dentin; d, deep dentin; c, cervical dentin), and divided into groups based on anatomical locations and luting resins (Super-Bond C&B: SB; Panavia F 2.0: PF; RelyX Unicem: RU): ...
